Little if any cutaneous production of vitamin D3 occurs at latitudes above and below 35° N and 35° S during the winter months. It was postulated that those residing in tropics synthesize enough vitamin D3 year round. Several studies have documented the effect of latitude, season and time of the day on the cutaneous production of vitamin D3 in an ampoule model. Studies from India have shown high prevalence of vitamin D deficiency despite abundant sunshine.

Quantification of the disease burden caused by different risks informs prevention by providing an account of health loss different to that provided by a disease-by-disease analysis. No complete revision of global disease burden caused by risk factors has been done since a comparative risk assessment in 2000, and no previous analysis has assessed changes in burden attributable to risk factors over time.

Recently low dose organochlorine (OC) pesticides have been strongly linked to various chronic diseases including diabetes and cardiovascular diseases. Both field and animal studies have suggested a possibility that persistent lipophilic chemicals like OC pesticides can cause vitamin D deficiency, but there have been no human studies of exposure to any chemical as a possible cause of vitamin D deficiency. This study was performed to examine if serum concentrations of OC pesticides were associated with serum concentrations of 25-hydroxyvitamin D (25(OH)D) in the U.S. general population.

The tummy, they say, is a mirror of emotions. A stick of a girl in the outpatients department of All India Institute of Medical Sciences (AIIMS), Delhi, has a stomach issue. In that crowded OPD, where everybody befriends everybody to while away the waiting hours, she sits like a zombie, eyes fixed on the ground. Her parents don't quite know why she gets those excruciating bellyaches.

More than half a million children in the country could be suffering from rickets, a debilitating disease associated with poor nutrition and lack of sunlight, officials said quoting a recent survey.

The National Rickets Survey 2008 based its estimate on its finding that 197 out of 20,000 children (0.99 per cent) had rickets, Integrated Regional Information Networks (IRIN) reported.

So says a multi-centric study on nutrition-related diseases in women

NEW DELHI: A country-wide survey has indicated high prevalence of obesity, hypertension, diabetes and high cholesterol levels in women over 35 years of age in India.

This paper reviews recent evidence on food intake and nutrition in India. It attempts to make sense of various puzzles, particularly the decline of average calorie intake during the last 25 years. This decline has occurred across the distribution of real per capita expenditure, in spite of increases in real income and no long-term increase in the relative price of food. One hypothesis is that calorie requirements have declined due to lower levels of physical activity or improvements in the health environment.

This paper seeks to measure deprivation in terms of physical development and calorie-intake of children in two villages of Orissa.
