Abstract
OBJECTIVE: To assess recent trends in obesity, health beliefs, and lifestyles in Swedish schoolchildren, with focus on socioeconomic disparities. METHOD: The study was conducted in two areas with high and low socioeconomic status (SES). 340 11-12 year olds participated in three cross-sectional surveys assessing food-related behaviours, physical activity and health beliefs, together with anthropometric examinations. Comparisons were made before and after a community-based intervention (2003 versus 2008) within the low-SES school, and between the low and high-SES school (2008 only). RESULTS: In the low-SES school BMI z-score decreased over 5 years (0.80 vs 0.46) as did the percentage of children frequently consuming sweet drinks (43.5 vs 26.8%), statistically significant in girls only (p<0.05). Children increasingly perceived benefits of healthy life-styles (37 vs 55%). In 2008, consumption of breakfast, vegetables, sweets and sweet drinks differed between schools, as did screen-time and physical activity, all in favour of the high SES-school where the obesity-prevalence was significantly lower (0.8 vs 6.7%). CONCLUSION: Positive changes in diet and weight status were observed, especially in girls, within a low-income multi-ethnic community undergoing a health promotion intervention. Our results underscore the multifactorial etiology of childhood obesity and the importance of continuing tailored, gender-sensitive prevention efforts.
