Childhood and adolescent overweight and obesity are increasing in China, but limited information is available on its secular trends in Guangzhou. In this cross-sectional study, ten-wave successive data were obtained from the physical fitness surveillance for students in Guangzhou from 2003 to 2012. A total of 2,619,154 urban students aged 7-18 years were included. The age-standardized prevalence of overweight and obesity increased significantly over the period: overweight rose from 10.15% to 14.07% in boys and 6.39% to 8.11% in girls, while obesity increased from 5.65% to 8.31% for boys and 3.43% to 4.12% for girls, respectively (P < 0.05). The increasing trend was significant across almost all age-sex-specific groups (P < 0.05), especially in the last five years. The prevalence of overweight and obesity grew continuously in both sexes, but the pace of change for boys were faster than that for girls. The highest prevalence of overweight was found among 10- to 12-year-old boys, that of obesity among 7- to 9-year-old boys and girls. In conclusion, overweight and obesity have increased significantly among urban children and adolescents in Guangzhou during 2003-2012. Further analysis of influencing factors and comprehensive interventions are urgently needed to combat the obesity epidemic among urban children and adolescents in Guangzhou.
中国儿童和青少年超重和肥胖的发生率正在增加，但关于广州这方面的长期趋势的信息却有限。在这项横断面研究中，我们从 2003 年至 2012 年广州学生体质监测中获得了十次连续的数据。共纳入了 2619154 名城市 7-18 岁学生。超重和肥胖的年龄标准化患病率在此期间显著增加：男生的超重率从 10.15%上升到 14.07%，女生从 6.39%上升到 8.11%，而肥胖率在男生中从 5.65%上升到 8.31%，在女生中从 3.43%上升到 4.12%（P<0.05）。这种增长趋势在几乎所有年龄和性别特定的群体中都非常显著（P<0.05），尤其是在过去五年中。男女超重和肥胖的患病率都在持续增长，但男孩的变化速度快于女孩。超重的最高患病率出现在 10-12 岁的男孩中，肥胖的最高患病率出现在 7-9 岁的男孩和女孩中。总之，2003-2012 年间，广州城市儿童和青少年的超重和肥胖率显著增加。需要进一步分析影响因素并采取综合干预措施，以应对广州城市儿童和青少年肥胖的流行。
