AIM: To explore developmental trajectories among adolescents of @entity14968 and overweight in relation to gender. METHODS: A group-based procedure was used to determine patterns of @entity132 in a school-based sample of 3020 Swedish adolescents followed from age 11 to 18. A sensitivity analysis was performed to compensate for an increasing number of missing height and weight data after grade 8. RESULTS: Six trajectories represented the best description of developmental @entity132 with the exception of @entity14968 among @entity1 , which was best described by four trajectories. Concerning @entity14968 , 5.9% of @entity1 and 4.2% of @entity1 developed this condition during the study period, while 1.9% of @entity1 and 3.0% of @entity1 recovered from their initial @entity14968 . For overweight, (including @entity28 ) 1.5% of @entity1 and 3.1% of @entity1 developed this weight disturbance during the study period, while 10.1% of @entity1 and 9.3% of @entity1 recovered from overweight/ @entity28 . Non-reporting of height and weight was biased towards an underestimation of the true prevalence of overweight and @entity28 in @entity1 and of @entity14968 in @entity1 . CONCLUSIONS: Developmental trajectories provide a novel method to describe the dynamics of @entity132 during adolescence. Similar patterns were found for overweight and @entity14968 in @entity1 and @entity1 but group sizes varied between genders. Non-reporting of height and weight was found in a gender-specific pattern.
