目的通过对比不同营养状况中小学生的运动素质,探讨肥胖、营养不良与运动素质的关系。方法按分层整群抽样原则,在北京市抽取城郊7个区7~17岁6 600名中小学生,检测身高、体重、50 m跑、立定跳远、仰卧起坐/引体向上、耐力跑、坐位体前屈等指标,并对检测结果进行分析。结果中小学生肥胖检出率为13.89%,营养不良检出率7.40%。4个学段男女学生中,肥胖学生与正常学生运动成绩比较,50 m跑、立定跳远和仰卧起坐/引体向上、耐力跑成绩差异均有统计学意义(P值均<0.01),且肥胖学生成绩均低于正常学生。营养不良学生与正常学生相比,相对肥胖学生与正常学生成绩差异较小。但50 m跑、立定跳远、坐位体前屈3个项目,营养不良学生成绩均差于正常学生。结论肥胖和营养不良能引起少年儿童运动素质的降低。应尽早采取干预措施,预防和控制儿童肥胖和营养不良的发生。
Objective To compare the sports quality of primary and secondary school students in different nutritional status and to explore the relationship between obesity, malnutrition and sports quality. Methods According to the principle of stratified cluster sampling, 6 600 primary and secondary school students from 7 to 17 years old in 7 suburb districts of Beijing were sampled for height, weight, 50 m running, standing long jump, sit-ups / pull-ups, endurance running, Sitting body flexion and other indicators, and the test results were analyzed. Results The prevalence of obesity in primary and secondary school students was 13.89%, and the detection rate of malnutrition was 7.40%. Among the four sections, male and female students in obese and obese students compared with those in normal students. There was significant difference in sports scores between 50m race, standing long jump and sit-ups / pull-ups, and endurance running scores (P <0.01) Obese students score lower than normal students. Malnourished students compared with normal students, the relative obesity students and normal students the difference is small. However, 50 m ran, standing long jump, seat body flexion three projects, malnourished students were worse than normal students. Conclusion Obesity and malnutrition can cause children’s exercise quality reduced. Interventions should be taken as early as possible to prevent and control childhood obesity and malnutrition.
