目的探讨7~9岁小学生肥胖与哮喘的关系,明确下一步研究的方向。方法采用整群抽样方法,随机抽取上海市6所学校的小学部,调查被抽中学校的所有1年级和2年级学生的家长,并对学生进行体格检查。率的比较采用卡方检验,学龄儿童中心性肥胖与哮喘的多因素分析采用logistic回归分析方法。结果学生肥胖率为9.40%,中心性肥胖率为16.41%,曾经患过哮喘的比例为4.37%。单因素分析中用体质指数(BMI)评价学生的营养状况,肥胖与非肥胖组比较患哮喘的比例差异无统计学意义,但是用腰围进行评价则显示腰围超标与哮喘有关。多因素分析的结果显示男生、年龄增长、周末睡眠时间少、食欲好、不挑食、饭量大、吃饭速度快是中心性肥胖的危险因素,在模型中有哮喘史是中心性肥胖的影响因素。结论 7~9岁小学生的中心性肥胖与哮喘有关,需要继续跟踪研究肥胖的影响因素,深入探讨肥胖与哮喘的相互关系,为公共卫生实践提供更多的证据。
Objective To explore the relationship between obesity and asthma in school-age children aged 7-9 years and clarify the direction of further study. Methods A cluster sampling method was used to randomly select the primary schools of six schools in Shanghai to investigate the parents of all grade one and grade two students who were drawn from secondary schools and to conduct physical examination of students. Rates were compared using chi-square test, multivariate analysis of school-age children with central obesity and asthma using logistic regression analysis. Results The student obesity rate was 9.40%, the central obesity rate was 16.41%, and the rate of suffering from asthma was 4.37%. Univariate analysis used body mass index (BMI) to evaluate the nutritional status of students. There was no significant difference in the proportion of asthma between obese and non-obese subjects. However, the assessment of waist circumference showed that excessive waist circumference was associated with asthma. The results of multivariate analysis showed that male students, age growth, less weekend sleep time, good appetite, not picky eaters, large appetite, eating fast is a central risk factor for obesity, asthma history in the model is the central obesity. Conclusions The central obesity of school-age children aged 7-9 years is related to asthma. It is necessary to follow-up and study the influencing factors of obesity and to explore the interrelationship between obesity and asthma in order to provide more evidence for public health practice.
