Aim: To increase knowledge of self-rated health and lifestyle in relation to overweight/obesity among 13–15 year olds in northern Sweden. Methods: All 6768 13–15 year olds in nine out of 15 municipalities in Västerbotten County were asked to complete a cross-sectional school-based on-line survey in 2007. Eighty-two per cent participated in the study. Responses were considered reliable for 74% of the participants (2517 boys/2470 girls). The survey addressed demography, self-rated health, self-reported weight, height, and lifestyle characteristics. Simple and multiple logistic regression analyses were used. Results: Overweight/obesity (ISO body mass index ≥25 kg/m 2 ) was more prevalent among boys (20%) than girls (11%), but more girls (19%) than boys (9%) reported fair or bad health. Overweight/obese boys and girls were more often physically inactive. For the boys, overweight/obesity was also associated with skipping breakfast, insufficient tooth brushing, and using snuff. For the girls, overweight/obesity was also associated with living with one parent and more television watching. Boys reported healthier habits concerning sleep duration, physical activity, eating breakfast, and smoking compared to the girls. On the other hand, girls reported better dietary and tooth brushing habits. Conclusions: This study uncovered two alarming findings: a fifth of the boys were overweight/obese and a fifth of the girls reported fair or bad health. Girls living with a single parent and boys and girls with unhealthy lifestyles were more likely to be overweight. Our findings emphasise the need for developing and implementing effective health promotion strategies for school-aged children to prevent an overweight and obesity epidemic that could continue into adulthood.
