Abstract AIM: To assess the 5-year secular changes in sports participation, sedentary activity, and physical self-perceptions among Hong Kong adolescents. METHODS: A total of 2932 and 5692 secondary students, aged 13-18 participated in the Health Related Behavior General (HRBG) Survey in 1995-1996 and 2000-2001, respectively. Extracurricular sports participation at least weekly or as a team member (none, 1-2 events, 3 or more events), sedentary activities (0-1 h/day, 2 h/day or more) including television/video watching and homework were assessed. Additionally, physical self-perceptions, physical fitness (fit/very fit, moderately fit, unfit/very unfit) and body weight (intention to lose weight, satisfied, intention to gain weight) were reported. Secular trends of sports participation, and sedentary activities and physical self-perceptions were assessed. RESULTS: During the 5 years, the prevalence of sports participation (at least weekly or membership) decreased significantly in boys. The prevalence of both TV/video watching and homework for at least 2 h/day increased significantly in both sexes. The prevalence of being unfit/very unfit increased significantly in girls. No significant secular difference in weight perception was observed for both sexes. CONCLUSIONS: Sports participation decreased and sedentary activities increased during the 5-year period. Physical self-perceptions did not change significantly, except an increase in being physically unfit was observed in girls. © 2010 The Author(s)/Journal Compilation © 2010 Foundation Acta Paediatrica.
