目的了解郴州市初中学生身体形态现状,为开展学校健康教育提供参考依据。方法选择郴州市6所学校部分初中生作为检测对象,采用2007年WHO年龄别身高筛查生长迟滞,年龄别体质指数筛查消瘦,计算两类营养不良检出率。参照国际生命科学学会中国肥胖工作组(WGOC)颁布的《中国学生超重、肥胖BMI筛查标准》,计算各年龄组男、女生超重和肥胖检出率。结果调查2566人,生长迟滞率发生为4.36%,消瘦率为6.39%,超重率为9.63%,肥胖率为2.18%。男生超重、肥胖检出率显著高于女生且差异有统计学意义(P<0.01),而在生长迟滞、消瘦发生率男女生差异则无统计学意义(P>0.05)。结论郴州市初中学生的消瘦和肥胖的检出率低于全国平均水平,但是仍需要重视生长迟滞及男生超重、肥胖的预防。
Objective To understand the physical status of middle school students in Chenzhou and to provide a reference for carrying out health education in schools. Methods Six middle school students from 6 schools in Chenzhou City were selected as the test subjects. The growth retardation was screened by the age of WHO in 2007, and the body mass index of age and body weight were screened. The detection rate of two kinds of malnutrition was calculated. According to the Chinese Students’ Overweight and Obesity BMI Screening Standards promulgated by the Chinese Obesity Working Group (WGOC) of International Life Science Society, the detection rates of overweight and obesity among men and women in each age group were calculated. Results 2566 people were surveyed, the rate of growth retardation was 4.36%, the rate of wasting was 6.39%, the rate of overweight was 9.63% and the rate of obesity was 2.18%. The detection rate of overweight and obesity in boys was significantly higher than that in girls (P <0.01), while there was no significant difference between boys and girls in the incidence of growth retardation and weight loss (P> 0.05). Conclusion The prevalence of weight loss and obesity in junior high school students in Chenzhou City is lower than the national average, but still need to pay attention to the growth retardation and the prevention of overweight and obesity in boys.
