"Journal of Clinical and Diagnostic Research is at present a well-known Indian originated scientific journal which started with a humble beginning. I have been associated with this journal since many years. I appreciate the Editor, Dr. Hemant Jain, for his constant effort in bringing up this journal to the present status right from the scratch. The journal is multidisciplinary. It encourages in publishing the scientific articles from postgraduates and also the beginners who start their career. At the same time the journal also caters for the high quality articles from specialty and super-specialty researchers. Hence it provides a platform for the scientist and researchers to publish. The other aspect of it is, the readers get the information regarding the most recent developments in science which can be used for teaching, research, treating patients and to some extent take preventive measures against certain diseases. The journal is contributing immensely to the society at national and international level."

" Journal of Clinical and Diagnostic Research (JCDR) is a multi-specialty medical and dental journal publishing high quality research articles in almost all branches of medicine. The quality of printing of figures and tables is excellent and comparable to any International journal. An added advantage is nominal publication charges and monthly issue of the journal and more chances of an article being accepted for publication. Moreover being a multi-specialty journal an article concerning a particular specialty has a wider reach of readers of other related specialties also. As an author and reviewer for several years I find this Journal most suitable and highly recommend this Journal."

Dr. Mamta Gupta,
"It gives me great pleasure to be associated with JCDR, since last 2-3 years. Since then I have authored, co-authored and reviewed about 25 articles in JCDR. I thank JCDR for giving me an opportunity to improve my own skills as an author and a reviewer.
It 's a multispecialty journal, publishing high quality articles. It gives a platform to the authors to publish their research work which can be available for everyone across the globe to read. The best thing about JCDR is that the full articles of all medical specialties are available as pdf/html for reading free of cost or without institutional subscription, which is not there for other journals. For those who have problem in writing manuscript or do statistical work, JCDR comes for their rescue.
The journal has a monthly publication and the articles are published quite fast. In time compared to other journals. The on-line first publication is also a great advantage and facility to review one's own articles before going to print. The response to any query and permission if required, is quite fast; this is quite commendable. I have a very good experience about seeking quick permission for quoting a photograph (Fig.) from a JCDR article for my chapter authored in an E book. I never thought it would be so easy. No hassles.
Reviewing articles is no less a pain staking process and requires in depth perception, knowledge about the topic for review. It requires time and concentration, yet I enjoy doing it. The JCDR website especially for the reviewers is quite user friendly. My suggestions for improving the journal is, more strict review process, so that only high quality articles are published. I find a a good number of articles in Obst. Gynae, hence, a new journal for this specialty titled JCDR-OG can be started. May be a bimonthly or quarterly publication to begin with. Only selected articles should find a place in it.
An yearly reward for the best article authored can also incentivize the authors. Though the process of finding the best article will be not be very easy. I do not know how reviewing process can be improved. If an article is being reviewed by two reviewers, then opinion of one can be communicated to the other or the final opinion of the editor can be communicated to the reviewer if requested for. This will help ones reviewing skills.
My best wishes to Dr. Hemant Jain and all the editorial staff of JCDR for their untiring efforts to bring out this journal. I strongly recommend medical fraternity to publish their valuable research work in this esteemed journal, JCDR".

"I wish to thank Dr. Hemant Jain, Editor-in-Chief Journal of Clinical and Diagnostic Research (JCDR), for asking me to write up few words.
Writing is the representation of language in a textual medium i e; into the words and sentences on paper. Quality medical manuscript writing in particular, demands not only a high-quality research, but also requires accurate and concise communication of findings and conclusions, with adherence to particular journal guidelines. In medical field whether working in teaching, private, or in corporate institution, everyone wants to excel in his / her own field and get recognised by making manuscripts publication.


Authors are the souls of any journal, and deserve much respect. To publish a journal manuscripts are needed from authors. Authors have a great responsibility for producing facts of their work in terms of number and results truthfully and an individual honesty is expected from authors in this regards. Both ways its true "No authors-No manuscripts-No journals" and "No journalsNo manuscriptsNo authors". Reviewing a manuscript is also a very responsible and important task of any peer-reviewed journal and to be taken seriously. It needs knowledge on the subject, sincerity, honesty and determination. Although the process of reviewing a manuscript is a time consuming task butit is expected to give one's best remarks within the time frame of the journal.
Salient features of the JCDR: It is a biomedical, multidisciplinary (including all medical and dental specialities), e-journal, with wide scope and extensive author support. At the same time, a free text of manuscript is available in HTML and PDF format. There is fast growing authorship and readership with JCDR as this can be judged by the number of articles published in it i e; in Feb 2007 of its first issue, it contained 5 articles only, and now in its recent volume published in April 2011, it contained 67 manuscripts. This e-journal is fulfilling the commitments and objectives sincerely, (as stated by Editor-in-chief in his preface to first edition) i e; to encourage physicians through the internet, especially from the developing countries who witness a spectrum of disease and acquire a wealth of knowledge to publish their experiences to benefit the medical community in patients care. I also feel that many of us have work of substance, newer ideas, adequate clinical materials but poor in medical writing and hesitation to submit the work and need help. JCDR provides authors help in this regards.
Timely publication of journal: Publication of manuscripts and bringing out the issue in time is one of the positive aspects of JCDR and is possible with strong support team in terms of peer reviewers, proof reading, language check, computer operators, etc. This is one of the great reasons for authors to submit their work with JCDR. Another best part of JCDR is "Online first Publications" facilities available for the authors. This facility not only provides the prompt publications of the manuscripts but at the same time also early availability of the manuscripts for the readers.
Indexation and online availability: Indexation transforms the journal in some sense from its local ownership to the worldwide professional community and to the public.JCDR is indexed with Embase & EMbiology, Google Scholar, Index Copernicus, Chemical Abstracts Service, Journal seek Database, Indian Science Abstracts, to name few of them. Manuscriptspublished in JCDR are available on major search engines ie; google, yahoo, msn.
In the era of fast growing newer technologies, and in computer and internet friendly environment the manuscripts preparation, submission, review, revision, etc and all can be done and checked with a click from all corer of the world, at any time. Of course there is always a scope for improvement in every field and none is perfect. To progress, one needs to identify the areas of one's weakness and to strengthen them.
It is well said that "happy beginning is half done" and it fits perfectly with JCDR. It has grown considerably and I feel it has already grown up from its infancy to adolescence, achieving the status of standard online e-journal form Indian continent since its inception in Feb 2007. This had been made possible due to the efforts and the hard work put in it. The way the JCDR is improving with every new volume, with good quality original manuscripts, makes it a quality journal for readers. I must thank and congratulate Dr Hemant Jain, Editor-in-Chief JCDR and his team for their sincere efforts, dedication, and determination for making JCDR a fast growing journal.
Every one of us: authors, reviewers, editors, and publisher are responsible for enhancing the stature of the journal. I wish for a great success for JCDR."

Dr. Shankar P.R.

"On looking back through my Gmail archives after being requested by the journal to write a short editorial about my experiences of publishing with the Journal of Clinical and Diagnostic Research (JCDR), I came across an e-mail from Dr. Hemant Jain, Editor, in March 2007, which introduced the new electronic journal. The main features of the journal which were outlined in the e-mail were extensive author support, cash rewards, the peer review process, and other salient features of the journal.
Over a span of over four years, we (I and my colleagues) have published around 25 articles in the journal. In this editorial, I plan to briefly discuss my experiences of publishing with JCDR and the strengths of the journal and to finally address the areas for improvement.
My experiences of publishing with JCDR: Overall, my experiences of publishing withJCDR have been positive. The best point about the journal is that it responds to queries from the author. This may seem to be simple and not too much to ask for, but unfortunately, many journals in the subcontinent and from many developing countries do not respond or they respond with a long delay to the queries from the authors 1. The reasons could be many, including lack of optimal secretarial and other support. Another problem with many journals is the slowness of the review process. Editorial processing and peer review can take anywhere between a year to two years with some journals. Also, some journals do not keep the contributors informed about the progress of the review process. Due to the long review process, the articles can lose their relevance and topicality. A major benefit with JCDR is the timeliness and promptness of its response. In Dr Jain's e-mail which was sent to me in 2007, before the introduction of the Pre-publishing system, he had stated that he had received my submission and that he would get back to me within seven days and he did!
Most of the manuscripts are published within 3 to 4 months of their submission if they are found to be suitable after the review process. JCDR is published bimonthly and the accepted articles were usually published in the next issue. Recently, due to the increased volume of the submissions, the review process has become slower and it ?? Section can take from 4 to 6 months for the articles to be reviewed. The journal has an extensive author support system and it has recently introduced a paid expedited review process. The journal also mentions the average time for processing the manuscript under different submission systems - regular submission and expedited review.
Strengths of the journal: The journal has an online first facility in which the accepted manuscripts may be published on the website before being included in a regular issue of the journal. This cuts down the time between their acceptance and the publication. The journal is indexed in many databases, though not in PubMed. The editorial board should now take steps to index the journal in PubMed. The journal has a system of notifying readers through e-mail when a new issue is released. Also, the articles are available in both the HTML and the PDF formats. I especially like the new and colorful page format of the journal. Also, the access statistics of the articles are available. The prepublication and the manuscript tracking system are also helpful for the authors.
Areas for improvement: In certain cases, I felt that the peer review process of the manuscripts was not up to international standards and that it should be strengthened. Also, the number of manuscripts in an issue is high and it may be difficult for readers to go through all of them. The journal can consider tightening of the peer review process and increasing the quality standards for the acceptance of the manuscripts. I faced occasional problems with the online manuscript submission (Pre-publishing) system, which have to be addressed.
Overall, the publishing process with JCDR has been smooth, quick and relatively hassle free and I can recommend other authors to consider the journal as an outlet for their work."

Abstract

Background: Anaemia is one of India’s major public health problems. The prevalence of anaemia was found to range from 30% to 98% in different studies from different regions. The National Family Health Survey–3 data showed that Punjab, along with Manipur, Mizoram, Goa, and Kerala, had the lowest levels of anaemia throughout the country.

Objectives: The present study was designed to assess the prevalence of anaemia among the apparently healthy young males and females from rural Punjab.

Methods: The young population, both males (5-20 years) and females (5-30 years) from rural Punjab, was studied for the prevalence of anaemia with respect to the body mass index, the activity profile and the socio-economic status.

Results: The prevalence of anaemia in females (5-30 years) was 89.5%, which included 49.8% of mild, 38.2% of moderate and1.5% of severe anaemia cases. The prevalence of anaemia in males (5-20 years) was 89.9%, with 51.2% suffering from mild, 38% from moderate and 0.7% from severe anaemia. Both males and females who were in the younger age group, who were underweight, who belonged to a lower socio-economic status and who had a low activity life style, had a higher prevalence of anaemia.

Conclusions: The present study found a high prevalence of anaemia in both males and females in the rural population, thus indicating that the problem of anaemia was related to a wider population than the traditional groups of the pregnant and lactating females and children. More detailed studies are needed to find out the cause and the type of anaemia along with other risk factors in all the age groups, irrespective of sex.

Introduction
Anaemia is a global public health problem which affects both the developing and the developed countries and it is an indicator of poor nutrition and poor health with major consequences for human health, as well as for the social and economic development of a population. Worldwide, at any given moment, more individuals have iron-deficiency anaemia than any other health problem (1). Anaemia is the most common indicator which is used to screen for iron deficiency and so the terms anaemia, iron deficiency and iron deficiency anaemia are sometimes used interchangeably (2). Globally, anaemia affects 1.62 billion people, which corresponds to 24.8% of the population (3). Anaemia is one of the most common health problems in India which is much more prevalent in the rural than in the urban areas (4), (5). The prevalence of anaemia inpregnant and lactating females and children has been found to vary from 50-90% in different parts of India (5). The data from the District Nutrition Project (Indian Council of Medical Research) in 16 districts of 11 states of India, on the prevalence of anaemia in non-pregnant adolescent girls (11-18 years), showed rates as high as 90.1% for severe anaemia (Hemoglobin <7 g/dl) in 7.1% of the girls (6). Another report stated that over 90% of the Indian women, adolescent girls and children were anaemic (7). The National Family Health Survey-3 (8) data showed that 55% of the women and 24% of the men were anaemic and that Punjab, along with Manipur, Mizoram, Goa and Kerala had the lowest levels of anaemia throughout the country. Even in these states, however, more than 30 % of the women were found to be anaemic. Anaemia can result in maternal mortality, weakness, diminished physicaland mental capacity, increased morbidity from infectious diseases, perinatal mortality, premature delivery and low birth weight and impaired cognitive performance, motor development, and scholastic achievement in children (9). Studies have shown that infants who were born to mothers with severe anaemia had a higher risk of irreversible brain damage, lower school achievement, a reduced physical and exercise tolerance and a poor immune response (10). Anaemia in young children is a serious concern because it can result in an impaired cognitive performance, behavioural and motor development, lack of co-ordination, language development and scholastic achievement, as well as an increased morbidity from infectious diseases (8), (11). Anaemia in the school age children is associated with the retardation of growth, decreased immunity and a poor cognitive development which results in a lower Intelligence Quotient (IQ) and behavioural abnormalities (12). Moreover, studies from Egypt (13), India (14) and USA (15), (16) have conclusively shown that anaemia delays the psychomotor development and impairs the cognitive performance of infants, pre-school and school-aged children. Anaemia in childbearing women increases the maternal mortality (17), pre-natal and peri-natal infant loss and prematurity (18), (19). Studies from India have consistently shown an association between anaemia and under-nutrition (20) and the occurrence of anaemia in undernourished children and in those belonged to the poor socioeconomic status are a well documented fact (21)(22)(23). But studies have also revealed that anaemia was a major health problem among the well-nourished school children who belonged to the upper and middle socio-economic classes also (24). The low-cost food that is generally affordable to the poor is low in nutritional value and high in fats, sugars and additives and therefore, obesity is oftentimes a sign of poverty and malnutrition (25). Reports from countries such as the United States, Israel and Canada have shown that overweight and obese children had a higher prevalence of iron deficiency than the normal weight children (26), (27). Another possible reason for anaemia in the overweight and obese could be the poor bio-availability of iron in the Indian diets (23), as vegetarian diets are a poor source of iron (28). The rising trend of consuming snacks and junk foods which supply empty calories is also responsible for the so called ‘healthy’ but anaemic children. According to the classification of anaemia as a problem of public health significance, the prevalence of anaemia which was >40% was considered to be a severe public health problem, that which was <4.9% to be not a public health problem, that which was between 5.0 to 19.9% to be a mild public health problem and that which was between 20.0 to 39.9% to be a moderate public health problem (2) . India is facing a grave public health problem, since the prevalence of anaemia in India is > 40%. A vast amount of studies were done on pregnant females and young children, but reliable data on the prevalence of anaemia in the adult population (non- pregnant females and adult males) is not available (5), (29), especially among young males and females in Punjab, which was till recently considered to be a rich state. So, the present study was designed to assess the prevalence of anaemia among the apparently healthy, young males and females from the rural areas of Punjab.

Material and Methods

We studied 1221 young males (5-20 years) and 3099 females (5-30 years) from the rural areas in Punjab during the heath check up camps in villages around Bathinda and during the medicalcheck up of healthy attendants who accompanied the patients who visited the hospital for treatment.

Exclusion Criteria: The subjects below or above 5 to 20 years among the males, below or above 5 to 30 years among the females and pregnant females were not included in the study. Those suffering from any chronic disease like diabetes, hypertension, arthritis, renal disease or any gastrointestinal disease and those who were on some medication, whether desi or allopathic, were excluded from study. Only rural subjects were included in the study.

Criteria for anaemia: All the young males and females underwent haemoglobin (Hb) estimation by the Cyanmethaemoglobin Method which was used by all the studies to estimate the haemoglobin levels. The cyanmethemoglobin method is being commonly used and has been considered to be accurate as compared to the hemocue or the hematology counter (30). Anaemia was defined as an Hb of <13g/dl in males and an Hb of < 12g/dl in females. Mild anaemia was defined as an Hb of 10-12.9 g/dl in males and an Hb of 10-11.9 g/dl in females. Moderate anaemia was defined as an Hb of 7-9.9 g/dl and severe anaemia as an Hb of < 7 g/dl in both males and females.

Body mass index (BMI): All the individuals had their height and weight measured. BMI was calculated as the weight in kilograms, divided by the square of the height in meters. The BMI was further categorized into low (<18.5 kg/m2), normal (18.5-24.9 kg/m2) and high (>25 kg/m2) according to the WHO criteria (31).

Socioeconomic status (SES):
The socioeconomic status was represented by the approximate monthly family income. Three groups were constituted and the subjects were categorized into low SES (<5000), middle SES (5000-15000), and high SES (15000 and above).

Physical activity:
The individuals were asked about their habitual physical activity. The questionnaire was interviewer administered, focusing on classifying the individuals as having low, moderate and high-activity levels, based on the activities which were performed. According to the Netherlands Nutrition Council (32), a low level activity was required for occupations such as clerical work, driving, shop keeping, teaching, studying, housework and all other light occupations; a middle level activity was required for occupations such as factory work, plumbing, carpentry, and farming: and a high level activity was required for occupations such as manual work, rickshaw pulling, construction work, and regular sports.

Rural/Urban Classification: Subjects who belonged to areas which were governed by panchayats were classified as rural subjects and those from areas which were governed by municipal councils or corporations were classified as urban subjects.

Statistical Analysis: The results were analyzed on a percentage scale.

Results

The prevalence of anaemia in young females in the age group of 5-30 years (n-3099) with respect to the age, BMI, activity profile and socioe-conomic status (SES) in rural Punjab has been presented in (Table/Fig 1). The prevalence of anaemia in young females in our study was 89.5%, which included 49.8% mild, 38.2% moderate and 1.5% severe anaemia cases. The prevalence of anaemia was 95.2% among younger females of the age group of 5-9 years (n-807), 87% in the age group of 10-19 years and 88.6% in the age group of 20-30 years. The prevalence of anaemia in young males in the age group of 5-20years (n-1221) with respect to the age, BMI, activity profile and socio-economic status in rural Punjab has been presented in (Table/Fig 2). Almost similar results on the prevalence of anaemia as in the females were observed in the males of the age group of 5-20 years (n-1221), that is 89.9%, with 51.2% suffering from mild, 38% from moderate and 0.7% from severe anaemia. The prevalence of anaemia in males in both the age groups of 5 to 9 years (n-822) and 10-20 years (n- 399) was almost similar, that is 90.5% and 88.7% respectively. Both males and females who were in the younger age group, who were underweight, who belonged to a low socio-economic status and who had a low activity life style, had a higher prevalence of anaemia. In general, the mild anaemia was more prevalent as compared to the moderate and severe forms of anaemia in both males and females, but in theage group of 5 to 9 years, in those with a low activity life style. In females of the lower socio-economic group, moderate anaemia was more prevalent. Similarly, the moderate anaemia was more prevalent in young males in the age group of 5 to 9 years, in the obese, low activity life style and low socio-economic groups.

Discussion

The exact figures for the prevalence of anaemia vary from study to study, but there is no doubt that anaemia is an extremely serious public health problem in India, especially among the pregnant women and children. Our study presents the prevalence of anaemia among the rural males (5-20 years) and females (5-30 years) in Punjab. In our study, the overall prevalence of anaemia was 89.5% in females and 89.9% males, which was more than theglobal prevalence. The prevalence of anaemia in different regions of the world has been expressed in (Table/Fig 3). (Table/Fig 4) shows the global prevalence of anaemia including those in developed and developing countries and India (rural and urban), among children who were <5 years, children who were >5 years, men, women and pregnant women. (Table/Fig 5) shows the prevalence of anaemia in India according to different studies from different regions and population groups, along with the prevalence of anaemia in the present study. (Table/Fig 6) shows the prevalence of mild, moderate and severe anaemia among women (15-49 years) in some states of India,8 whereas in the present study, the prevalence of mild anaemia was 49.8%, that of moderate anaemia was 38.2% and that of severe anaemia was 1.5%, with a total prevalence of 89.5% among females in the age group of 5-30 years. Almost similar results were shown by Bulliyy et al (33)(34)(35)(36)(37), that the prevalence of mild, moderate and severe anaemia among non school going adolescent girls in three districts of Orissa were 45.2%, 46.9%, and 4.4%, while the total prevalence was 96.5%. In a study among the adolescent girls of Nepal, the prevalence of anaemia (68.8%) was found to be lower than that of the Indian females in the present study (89.5%) (38). Within India, the highest prevalence of anaemia was found in the Jharkhand State, where almost all the adolescent girls were anaemic (39), which was more as compared to the findings of our study. There is a paucity of studies which have explored the prevalence of anaemia among males in Punjab. In our study, the prevalence of anaemia among males (5-20 years) was 89.9%, which was much more as compared to a 24% prevalence of anaemia among men in the NFHS 3 data (8). In another study, the prevalence of anaemia in the 16-70 years age group among males was 44.3% (40). The present study highlights a higher prevalence of anaemia in males as compared to that in the existing data. (Table/Fig 7) shows a statewise prevalenceof anaemia among men (15-49 years), which showed a less prevalence of anaemia among males as compared to that in the present study. The prevalence of anaemia does not vary with the sex of the child and is considerably higher in the rural areas, among children of women with no education, among the scheduled castes and tribes and among children from households in the lower wealth quintiles. The anaemia status of the children is closely linked with the anaemia status of the mother (8). In the present study, the prevalence of anaemia was almost the same in 5 to 9 year old males (90.5%) as in females of the same age group (95.2%). The prevalence of anaemia decreases with an increase in the standard of living index among both males and females (15-49 years), as shown in (Table/Fig 8). A similar trend was also observed in the National Family Health Survey 2 (41) (NFHS 2) data, where the prevalence of anaemia in women (15-49 years) was 60.2% in the low, 50.3% in the medium and 41.9% in the high living index group. Aggarwal, et al (42), in a government school based study from a middle socio-economic group of North East Delhi, reported the prevalence of anaemia as 45%. A study by Jondhale, et al. (43) reported the prevalence of anaemia as 14% in adolescent girls where the household income was more than Rs. 5000 per month and as 26% where the household income was less than Rs. 5000 per month. The same trend was expressed in the present study and the prevalence of anaemia was found to be decreased with an increase in the socioeconomic status. It was 96.3% among the low socio-economic group males, 86.9% among the middle socioeconomic group males and 84.6% among the high socio-economic group males, whereas the prevalence was 98.8%, 87.6% and 89.8% among females of the low, middle and the high socio-economic group. In the literature, there is a paucity of data regarding the prevalence of anaemia with respect to the BMI in young males and females in Punjab. A study by Ramachandra et al. (44) has shown the association between the higher prevalence of anaemia and a low BMI. In the NFHS 2 study (41), it was stated that shorter women and women with a low BMI had a somewhat higher prevalence of anaemia than other women. In our study also, the prevalence of anaemia in females was found to increase with a decrease in the BMI, that is, the prevalence was 91.4% in females with low BMI, 83.6% in those with normal BMI and 73.7% in females with high BMI. Similarly, in males, the prevalence of anaemia was 91.8%, 78.2% and 90.9% in those with low, normal and high BMI respectively. The pattern of anaemia by its characteristics is similar for men and women, except for the differentials by age. Age is not an important determinant of anaemia in women, but the anaemia varies substantially by age for men. The prevalence of anaemia was more than 50% higher for men who were aged 15-19 years than for men who were aged 20-24 years. After the age of 20-24 years, the anaemia was found to increase steadily to a maximum of 33% for men who were aged 50-54 years (8). In the present study, the prevalence of anaemia was found to be consistent with the above statement and it was 90.5% in males of the younger age group (5-9 years) and 88.7% in males of the older age group (10 to 20 years). But in our study, the results showed that females in the age group of 5-9 years had a more moderate anaemia (67.7%) as compared to that in the age group of 20-30 years (42.6%). This was paradoxical, as menstruating females are more likely to be anaemic. The limitation of our study was that we did not do the sub group analysis of the correlation between BMI and anaemia, as the prevalence of severe malnutrition in females of the age group of 5 to 9 years could have been one explanation for this paradox. Another possible reason for this could have been the poor bio-availability of iron in the Indian diet (23). Another reason which we did not explore was the type of diet which was consumed by the study population, as evidence indicated a higher prevalence of anaemia among children who had a vegetarian diet, because vegetarian diets are a poor source of iron (28), (45). Verma et al. (24) also found a higher prevalence of anaemia among the vegetarian than the non-vegetarian schoolgirls (66% vs. 38%). In developing countries such as India, the poor bio-availability of dietary iron, coupled with a low intake of iron which was derived from animal foods, is a major aetiological factor for anaemia (46). Other important reason which could not be investigated in our study was that young females may have been receiving some iron supplements from the health centers, thus leading to a lesser prevalence of anaemia in the age group of 20-30 years than in the 5-9 years age group. Although the dietary habits of the children were not studied in present study, it was likely that females of the 5-9 years age group may have taken a nutritionally deficient diet and may have been more susceptible to parasitic infestations and other chronic infections, thus leading to a higher prevalence of anaemia. However, more studies are needed to support or disapprove this observation. The prevalence of anaemia does not vary much by the work status, but women who do not work have a slightly less prevalence of anaemia than the working women (41). In the present study also, the activity profile did not correlate with any specific degree of anaemia. According to the WHO, if the prevalence of anaemia at the community levels was more than 40%, it was considered as a problem of high magnitude (2). The present study thus brings out the fact that the problem of anaemia was related to a wider population than the traditionally considered groups of the pregnant females, lactating females and children. The young male population was equally susceptible in Punjab. Studies have shown that anaemia was an indicator of poor nutrition and poor health, with major consequences on the human health as well as on the social and economic development. Anaemia was linked to a depressed mental state and motor development during infancy and early childhood, which may be irreversible (47). Anaemia during childhood also results in decreased physical activity and decreased interaction with the environment, with negative consequences on learning and school achievements (48). In economic terms, Horton and Ross estimated the magnitude of the loss of work productivity due to childhood anaemia to be 4.5% of the country’s Gross Domestic Product (GDP) (49). The estimates of the percentage of GDP which was lost to all forms of vitamin and mineral deficiencies including IDA are 1% for India, 0.9% for Bangladesh and 1.7% for Pakistan (50). Studies suggest that micronutrient deficiencies alone may cost India 2.5 billion US$ annually (51) and that the productivity losses (manual work only) from stunting, iodine deficiency and iron deficiency together are responsible for a total productivity loss of almost 3% of the GDP (52). The iron deficiency in adults has been estimated to decrease the productivity by 5-17%, depending on the nature of the work which is performed (52). The data from ten developing countries have shown that the median loss in the reduced work capacity which was associated with anaemia during adulthood was equivalent to 0.6% of the GDP, while an additional 3.4% of the GDP was lost due to the effects on the cognitive development, which was attributable to anaemia during childhood (49). Policy makers often fail to recognize the massive economic costs, service providers often fail to recognize the significant health consequences and societies are too often ignorant of anaemia’s capability to cause permanent cognitive defects, thus denying children their right to a full mental and emotional development, before they ever reach a classroom (53). That is why, we feel that the negative consequences of anaemia on the cognitive and physical development of children and on the physical performance, particularly the work productivity in adults, are of a major concern (2). The overall prevalence of anaemia in young males and females from the rural population in our study was relatively higher as compared to the national standards, thus indicating that the traditional rich state of Punjab, which was among the states with a lower prevalence of anaemia, as was documented by the NFHS-3, was in fact confronting with increasing threat of anaemia necessitates larger studies to be conducted, to know the prevalence of anaemia along with its cause, health and socio-economic implications in the rural as well as urban populations, irrespective of the age groups.

Conclusion

The present study found a high prevalence of anaemia in both males and females in the rural population of Punjab, thus indicating that the problem of anaemia was related to a wider population than the traditional groups of the pregnant and lactating females and children. Our study highlights the fact that the prevalence of anaemia was more in the younger age groups, in the low BMI groups, in the low socio-economic groups and in subjects with a sedentary life style. We suggest that there is a need for wellplanned, systematic and large-scale studies by using standardized methodologies to estimate the prevalence of anaemia as well as the causes of anaemia at the community level among males and females in all the age groups, with an accurate evaluation of the socio-economic status and the representation of the different regions of India. A comprehensive study, including anthropometric data, biochemical data, clinical signs and dietary intake data will give a better insight into the situation and more importantly, it will help in devising interventions for the prevention and the treatment of anaemia, which should be directed towards all members of the community, irrespective of age and sex.

Key Message

India is facing a grave public health problem, with the prevalence of anaemia in India being > 40%. Anaemia is an indicator of poor nutrition and poor health with major consequences for the human health, as well as for the social and economic development of a population. In our study, the prevalence of anaemia was 89.5% in females and 89.9% in males. It was more in the younger age groups, in the lower BMI groups, in the lower socio-economic groups and in those with a sedentary life style.
