Awareness About Anti-Smoking Related Laws and Legislation Among General Population in Slums of Delhi, India.

Introduction: Almost 40% of Delhi's population lives in slums and is vulnerable to tobacco use. It is therefore important to assess their opinion and ensure compliance to antismoking legislation. The present study was undertaken to assess the awareness of the general public residing in slums in Delhi regarding the smoke-free initiative of 2009, 3 years after intensive implementation. Methods: It was a cross-sectional study conducted among participants selected by cluster sampling from the slums in six districts of Delhi using a pretested semistructured questionnaire. A total of 708 slum dwellers were interviewed. Results: Out of the total, only 16.1% (n = 114) of the participants had heard of The Cigarettes and Other Tobacco Products (Prohibition of Advertisement and Regulation of Trade and Commerce, Production, Supply and Distribution) Act, 2003 (COTPA), though, they were aware about some of the provisions of the COTPA. Majority (n = 529; 74.7%) perceived the smoke-free zones as the places where smoking forms of tobacco are banned. Regarding the awareness about the places designated as smoke-free zones, 82.1% (n = 581) of the respondents named educational institutions. About 61% of the people interviewed reported to have seen people smoking at public places on the day of interview while only 21.5% reported to have seen any one getting punished for smoking. Conclusions: Awareness about COTPA was low. The study respondents perceived that no action was being taken against persons acting in violation of the law. Thus, there is a need for stricter implementation of COTPA and increased spreading of awareness among the general public. Implications: While awareness about antismoking legislation among general population (particularly slums) has been studied world over, this has not been the case in India. The study depicts opinion of one of the susceptible populations regarding tobacco control legislation, which has hitherto not been studied in the Indian context. This study has an important implication as it highlights the need for stringent enforcement of antismoking legislation for tobacco control.

Issues in prevention of iron deficiency anemia in India.

Iron deficiency anemia (IDA) continues to be major public health problem in India. It is estimated that about 20% of maternal deaths are directly related to anemia and another 50% of maternal deaths are associated with it. The question, therefore, is why, despite being the first country to launch the National Nutritional Anemia Prophylaxis Programme in 1970, the problem of IDA remains so widespread. As is to be expected, the economic implications of IDA are also massive. The issues of control of IDA in India are multiple. Inadequate dietary intake of iron, defective iron absorption, increased iron requirements due to repeated pregnancies and lactation, poor iron reserves at birth, timing of umbilical cord clamping, timing and type of complementary food introduction, frequency of infections in children, and excessive physiological blood loss during adolescence and pregnancy are some of the causes responsible for the high prevalence of anemia in India. In addition, there are other multiple programmatic and organizational issues. This review, therefore, is an attempt to examine the current burden of anemia in India, its epidemiology, and the various issues regarding its prevention and control, as well as to offer some innovative approaches to deal with this major health problem.

Prevalence of low glomerular filtration rate, proteinuria and associated risk factors in North India using Cockcroft-Gault and Modification of Diet in Renal Disease equation: an observational, cross-sectional study.

BACKGROUND: Chronic kidney disease (CKD) is increasingly being recognized as an emerging public health problem in India. However, community based estimates of low glomerular filtration rate (GFR) and proteinuria are few. Validity of traditional serum creatinine based GFR estimating equations in South Asian subjects is also debatable. We intended to estimate and compare the prevalence of low GFR, proteinuria and associated risk factors in North India using Cockcroft-Gault (CG) and Modification of Diet In Renal Disease (MDRD) equation. METHODS: A community based, cross-sectional study involving multistage random cluster sampling was done in Delhi and its surrounding regions. Adults > or = 20 years were surveyed. CG and MDRD equations were used to estimate GFR (eGFR). Low GFR was defined as eGFR < 60 ml/min/1.73 m2. Proteinuria (> or = 1+) was assessed using visually read dipsticks. Odds ratios, crude and adjusted, were calculated to ascertain associations between renal impairment, proteinuria and risk factors. RESULTS: The study population had 3,155 males and 2,097 females. The mean age for low eGFR subjects was 54 years. The unstandardized prevalence of low eGFR was 13.3% by CG equation and 4.2% by MDRD equation. The prevalence estimates of MDRD equation were lower across gender and age groups when compared with CG equation estimates. There was a strong correlation but poor agreement between GFR estimates of two equations. The survey population had a 2.25% prevalence of proteinuria. In a multivariate logistic regression analysis; age above 60 years, female gender, low educational status, increased waist circumference, hypertension and diabetes were associated with low eGFR. Similar factors were also associated with proteinuria. Only 3.3% of subjects with renal impairment were aware of their disease. CONCLUSION: The prevalence of low eGFR in North India is probably higher than previous estimates. There is a significant difference between GFR estimates derived from CG and MDRD equations. These equations may not be useful in epidemiological research. GFR estimating equations validated for South Asian populations are needed before reliable estimates of CKD prevalence can be obtained. Till then, primary prevention and management targeted at CKD risk factors must play a critical role in controlling rising CKD magnitude. Cost-benefit analysis of targeted screening programs is needed.

Dietary aspects of pregnant women in rural areas of Northern India.

The aim of this article is to document the current dietary profile of pregnant women in rural areas of Delhi. In order to explore the diet the combination of quantitative (24-h recall method) and qualitative methods (food frequency method) were used. The mean intake of macronutrients and micronutrients, namely, iron, folic acid and Vitamin C which play an important role in the pathophysiology of nutritional anaemia during pregnancy was calculated from the foodstuffs, using Nutritive Value of Indian Foods. The preferences and avoidance of various foods by the pregnant women were also elicited. The data were analysed using Epi Info 3.4. The intake of calories, protein, iron, folic acid and Vitamin C was found to be less than the recommended dietary allowance in 100%, 91.2%, 98.2%, 99.1% and 65.8% of pregnant women respectively. Folic acid intakes were significantly lower in younger, primiparous and poorly educated women from low-income families. Vitamin C intake was lower among non-Hindus only. The overall data suggested the presence of food gap rather than isolated deficiency of any particular nutrient.
