摘 要:目的 了解2007年和2011年广州市儿童少年超重和肥胖的流行情况及变化趋势.方法 资料来源于广州市中小学卫生保健所2007年和201 1年的体检数据.采用随机分层整群抽样方法,依据入校人数比例在广州市的4个行政区(天河区、越秀区、白云区和海珠区)抽取19所学校,以抽样单位内所有5 ~18岁学生作为研究对象,其中2007年27 944名,2011年38 284名.使用标准方法测量体重和身高,采用中国肥胖问题工作组推荐标准和WHO标准分别对7~18岁和5~6岁儿童少年进行超重、肥胖筛查,并分析其变化趋势.结果 7~18岁组肥胖率从2007年的5.96%(1 553/26 055)增长为2011年的6.56%(2 339/35 664),差异有统计学意义(x2=9.195,P<0.05);男生超重率[2007年为13.25%(1 766/13 329);2011年为13.87%(2 559/18 451)]和肥胖率[2007年为7.82%(1 042/13 329);2011年为8.63%(1 592/18 451)]明显高于女生[超重率:2007年为7.43%(946/12 726),2011年为8.17%(1 406/17 213);肥胖率:2007年为4.11%(523/12 726),2011年为4.48% (771/17 213)],差异有统计学意义(超重率:2007年,x2=236.123;2011年,x2=292.892;肥胖率:2007年,x2=158.533;2011年,x2=247.794.P均<0.05).2007年与2011年比较,仅16、17岁男生和12岁女生肥胖率明显增加[男生:16岁组:2007年为3.34%(64/1 919),2011年为4.98%(107/2 148),x2=6.820,P<0.05;17岁组:2007年为3.04%(58/1 908),2011年为4.38%(89/2 034),x2=4.893,P<0.05.女生:12岁组:2007年为3.13% (21/670),2011年为5.84%(43/736),x2=5.921,P<0.05].Joinpoint回归显示,男生10岁前肥胖率随年龄增长而升高[2007年年龄变化百分比(APC) =3.75,201 1年APC=1.76),10岁后年龄越高肥胖率越低(2007年10 ~18岁APC=-18.58;2011年10 ~18岁APC=-15.95).2007年女生7~9岁肥胖率呈上升趋势(APC=12.16),9~18岁肥胖率下降(APC=-17.23);2011年女生的肥胖率随年龄升高而�Objective This study aimed to explore the secular trends of overweight and obesity prevalence between 2007 and 2011 in children and adolescents in Guangzhou.Methods The data of physical examination was collected from the routine measurements carried out by the Health Care Facilities of Primary and Secondary schools between 2007 and 2011.Random stratified cluster sampling was conducted,all the students aged 5-18 yearn old form 19 primary and secondary schools from 4 districts (Tianhe district,Yuexiu district,Baiyun district and Haizhu district) were included in this survey,including 27 944 students in 2007 and 38 284 students in 2011.Body mass index reference norm established by Working Group on Obesity in China (WGOC) and the WHO cut-off criteria were employed for overweight and obesity screening,and the trend was analyzed.Results Prevalence of obesity in children and adolescents (7-18 years old) significantly increased from 5.96% (1 553/26 055) in 2007 to 6.56% (2 339/35 664) in 2011,and the difference showed statistical significance (x2 =9.195,P 〈 0.05).Overweight and obesity was more common in boys (overweight:13.25% (1 766/13 329) in 2007 and 13.87% (2 559/18 451) in 2011; obesity:7.82% (1 042/13 329) in 2007 and 8.63% (1 592/18 451) in 2011) than in girls (overweight:7.43% (946/12 726) in 2007 and 8.17% (1 406/17 213) in 2011 ; obesity:4.11% (523/ 12 726) in 2007 and 4.48% (771/17 213) in 2011),and the difference showed statistical significance (overweight:x2 =236.123 in 2007 and x2 =292.892 in 2011; obesity:x2 =158.533 in 2007 and x2 =247.794 in 2011.All P values 〈 0.05).Further analysis found that significant increases occurred in boys aged 16 and 17 years old and in girls aged 12 years old (boy:16 years old,x2 =6.820,P 〈0.05.17 years old,x2 =4.893,P 〈0.05.girl:12 years old,x2 =5.921,P 〈0.05).Results of Join-point regression showed that for boys less than 10 years old the prevalence increased with age increasi
