Eight years secular trends of physical self-esteem among Swedish adolescents.
The main aim of this study was to explore secular trends between 2000 and 2008 in physical self esteem by comparing cross sectional cohorts of young adolescents.


METHODS
Data of physical self esteem, mean steps per day and body mass index (BMI) were collected in comparable cohorts comprising 191 (103 girls) (2000) and 170 adolescents (101 girls) (2008) in a middle class Swedish community.


RESULTS
There was a significant higher Global Self-esteem in the cohort 2008 compared with the 2000 cohort both in boys (p = .004) and girls (p = .018). Regarding Physical Self-worth, both boys and girls reported higher mean values in 2008, which were however not significant. Boys classified overweight/obese showed a significant lower value in Global Self-esteem (p = .001) in the 2008 cohort when compared with the overweight/obese in the 2000 cohort, but all other domains showed non significant differences. Girls classified overweight/obese showed a significant lower value in Physical Strength (p = .023), in the 2008 cohort when compared with the overweight/ obese in the 2000 cohort, but all other domains showed non significant differences.


CONCLUSIONS
There was significantly higher Global Self-esteem in the cohort 2008 compared with the 2000 cohort both in boys and girls, and regarding Physical Self-worth, both boys and girls reported higher mean values in 2008 that were not significant. In the overweight/obese adolescents group, the only significant difference was a lower perceived Physical Strength in girls in 2008 and a significant lower Global Self-esteem in boys in 2008. Enhanced focus on physical activity in society and actions taken by the school might have influenced the result.
