title: Association of obesity and physical activity in adult males of Dharan, Nepal.
abstract: OBJECTIVE
  Obesity is one of the most apparent-yet most neglected public health problems. Physical activity is a crucial element in the development of obesity but still its importance in the occurrence of obesity varies in different populations. This paper aims to study the burden of obesity and its association with physical activity was carried out in a rapidly urbanizing town.
  
  
  METHODS
  A cross-sectional study to investigate the prevalence of obesity and its association with physical activity was carried out in one thousand adult males of Dharan municipality. Tools of data collection included interview and physical measurements such as blood pressure, height and weight measurements, and waist and hip circumferences. Odds ratios (ORs) and their 95% confidence intervals for obesity were computed across various demographic and other variables without adjusting and then adjusting for physical activity.
  
  
  RESULTS
  The prevalence of overweight and obesity in the population was 32.9% and 7.2% respectively. The study showed that physical inactivity is more importantly associated with obesity in the older population. The trend of young being more obese is reversed after adjusting for physical activity so that those in the older age were more obese than the younger ones. Similarly, those in to the business, vocational and clerical works, those who were more literate and those in the higher socio-economic status were significantly associated with obesity even after correcting for physical activity.
  
  
  CONCLUSIONS
  The prevalence of overweight and obesity is high in the males of Dharan. The value and effect of physical activity seem to vary across different age-groups and socio-economic status and occupations. The young, the technical persons or businessmen and the more prosperous ones probably need to bring down their calorie intake along with emphasis on physical activity in order to bring down their weight and cardiovascular risk.
