BACKGROUND
Little is known about the progression of obesity from childhood to adolescence. This study aimed to longitudinally examine the obesity status in a cohort of children across their childhood and adolescence, and to identify the factors associated with persistent obesity.
METHODS
The study used data from School Physical Fitness Award Scheme (SPFAS), a population-based programme in Hong Kong primary and secondary schools. Students were included if they participated in the SPFAS in both 2014 (Primary 1 and 2) and 2018 (Primary 5 and 6). Their anthropometric and physical fitness parameters were analyzed.
RESULTS
A total of 18,863 students were included. The baseline prevalence of obesity was 5.7 %. After 4 years, the prevalence increased to 6.7 %. Among those with obesity at baseline, 35.3 % remained obese after 4 years. The addition of baseline physical fitness level did not improve the prediction for persistent obesity.
CONCLUSIONS
One-third of obese students in junior primary school remained to be obese into adolescence. Their baseline physical fitness level did not improve the predictive value for future obesity. Further studies should investigate the prognostic factors that may influence the natural course of childhood obesity.
背景
儿童期至青春期肥胖的进展情况鲜为人知。本研究旨在对一个儿童队列的肥胖状况进行纵向研究，观察其从儿童期到青春期的变化，并确定与持续性肥胖相关的因素。
方法
本研究使用了香港中小学校体质健康奖励计划（SPFAS）的数据。如果学生在 2014 年（小一和小二）和 2018 年（小五和小六）均参加了 SPFAS，则将其纳入研究。分析了他们的人体测量学和体能参数。
结果
共纳入 18863 名学生。基线肥胖患病率为 5.7%。4 年后，患病率上升至 6.7%。在基线肥胖的学生中，35.3%在 4 年后仍然肥胖。基线体能水平的增加并不能提高对持续性肥胖的预测。
结论
小学低年级肥胖学生中，有三分之一在青春期仍保持肥胖。他们的基线体能水平并不能提高对未来肥胖的预测价值。应进一步研究可能影响儿童肥胖自然病程的预后因素。
