Energy balance of adolescent girls in rural area of Varanasi.

Although several studies have been undertaken on dietary intake of adolescent girls, studies on their energy expenditure and thereby energy balance are few. In order to explore these aspects, this community based cross-sectional study was done on 270 adolescent girls of a rural area of Varanasi, selected by adopting appropriate sampling technique. Nutritional status of study subjects was assessed on the basis of BMI. Their energy intake was computed by 24 hours recall oral questionnaire method. Estimation of energy expenditure was based on physical activity which was noted by 24 hours activity recall questionnaire method. Average energy intake (1609.42 +/- 528.87 kcal/day) of the study subjects was less than their mean energy expenditure (1896.19 kcal/day). Their energy expenditure was significantly influenced by several factors (e.g. age, caste, type of family, etc.) As much as 69.63%, subjects were in negative energy balance. Majority of subjects belonging to lower (79.37%) and middle (75.19%) SES were in the negative energy balance. Negative energy balance has been significantly less in subjects belonging to high SES, having main occupation of the family as business and high per capita income groups with respect to their corresponding subcategories. In all 68.52% study subjects had BMI < 18.5 kg/m2. Majority (91.11%) of adolescent girls had rate of energy expenditure > 1.4. Under nutrition was significantly (p<0.05) more in subjects with rate of energy expenditure > 1.4 (i.e. 70.33%) than in subjects with rate of energy expenditure < or = 1.4.

An epidemiological study of cannabis abuse among college students of Varanasi.

A study of 4326 students, selected by stratified random sampling and using a self administered questionnaire, revealed that overall cannabis abuse among them was 4.5%. It amounted to a considerable decline in prevalence compared to 10.2% observed in 1976. However, it was noted that this reduction was mainly in occasional users and the proportion of regular users has actually increased in 1986. The prevalence has also shown an increase among girl students. The regular users were mainly from professional colleges, hailing from metropolitan cities and with relatively higher amount of pocket money at their disposal. It was concluded that the observed trends could be due to peer pressures. It was also considered that health education of such students at entry point may help reduce the problem.
