Abstract
Introduction. Overweight and perception of being overweight, may lead adolescent to lose weight. The aim of the present study was to investigate overweight adolescents' self-perceived weight, body dissatisfaction, and weight control behaviour during 1994-2010 in Finland. Methods. The country-representative, cross-sectional data of 15-year olds were obtained from the Health Behaviour in School-aged Children (HBSC) study, conducted in 1994 (N = 1194; males: 48%), 1998 (N = 1545; 49%), 2002 (N = 1745; 50%), 2006 (N = 1670; 47%), and 2010 (N = 2082; 48%). Results. The majority of overweight boys (62-69%) and girls (89-100%) assessed themselves as too fat, and their body image was lower than in nonoverweight adolescents. The highest prevalence of current weight controlling was found in 2006 in males (18%) and in 2010 in females (39%). Conclusion. The phenomena were current and gender differences notable, but there was no statistically significant difference in overweight adolescents' self-perceived weight, body dissatisfaction, or weight control behaviour between survey years.
