The Prevalence of overweight and obesity in relation to social and behavioural factors in Lithuania

Abstract

Aim: To examine the association of social and health behaviour factors with overweight and obesity among Lithuanian adult population. Methods: Since 1994 fi ve cross-sectional surveys have been conducted among adult population aged 20-64 within the international Finbalt Health Monitor project. An independent national random sample of 3000 inhabitants of Lithuania was drawn from National Population Register for each survey. The data were collected through mailed questionnaires. The logistic regression was used for analysis of the associations. Results: In 2002 the prevalence of obesity (BMI >30 kg/m2) was 16% and the prevalence of overweight (BMI >25 kg/m2) 49.1%. Since 1994 both indicators have increased in men, while in women the prevalence of overweight has decreased by 9%. A positive relationship was found between age and both indicators. Lower education was related to higher BMI in women, while in men educational level had a positive association with BMI. Women living in cities were less obese and overweight than those living in towns and villages. Obesity and overweight were less prevalent among daily smokers and physically active persons. There was no consistent association between nutrition habits and the prevalence of obesity. Conclusion: The associations between BMI and social factors as well as behavioural factors should be taken into account in the elaboration of the National obesity control programme.
