title: Population-based intervention for cardiovascular diseases related knowledge and behaviours in Asian Indian women.
abstract: OBJECTIVE
  There is poor knowledge and behaviors regarding chronic diseases related nutritional and lifestyle factors among women in low income countries. To evaluate efficacy of a multilevel population-based intervention in improving knowledge and practices for related factors we performed a study in India.
  
  
  METHODS
  Population based study among women 35-70 years was performed in four urban and five rural locations. Stratified sampling was performed and we enrolled 4624 (rural 2616, urban 2008) of eligible 8000 women (58%). Demographic details, medical history, diet, physical activity and anthropometry were recorded and blood hemoglobin, glucose and total cholesterol determined. Knowledge and behaviors regarding diet in chronic diseases were inquired in a randomly selected 100 women at each site (n = 900). A systematic multilevel population based intervention (using posters, handouts, street plays, public lectures, group lectures and focused group discussions) was administered over 6 months at each site. The questionnaire was re-administered at the end in random 100 women (n = 900) and differences determined. Descriptive statistics are reported. Comparison of parameters before and after intervention was assessed using Mann Whitney test.
  
  
  RESULTS
  Prevalence (%) of chronic disease related lifestyles and risk factors in rural/urban women, respectively, was illiteracy in 63.6/29.4, smoking/tobacco use 39.3/18.9, high fat intake 93.6/93.4, high salt intake 18.2/12.6, low physical activity 59.5/70.2, overweight/obesity 22.5/45.6, truncal obesity 13.0/44.3, hypertension 31.6/48.2, hypercholesterolemia 13.5/27.7, and diabetes in 4.3/15.1 percent. Composite chronic diseases knowledge at baseline vs after intervention increased significantly in overall (32.0 vs 62.0), rural (29.0 vs 63.5) and urban (39.5 vs 60.5) groups (p < 0.001). Significant increase in knowledge regarding diet in hypertension, diabetes, heart disease and anemia as well as importance of dietary proteins, fats, fibres and fruits was observed (p < 0.001). There was insignificant change in most of the practices regarding intake of low fat, high protein, high fibre diet except sieving the flour which declined significantly (80.1 vs 53.6, p < 0.001).
  
  
  CONCLUSIONS
  A short-term multilevel population-wide intervention among women in rural and urban locations in India increased chronic disease knowledge but failed to influence practices.
