摘要
目的 探讨青年学生体重指数与其父母体重指数的关系,进一步了解遗传和环境因素在超重和肥胖流行中的作用,希望能为超重和肥胖的预防提供一定的指导。方法 按照中国肥胖问题工作组对中国成人体重指数(BMI)分类标准进行分组,即低BMI组(BMI<18.5),正常BMI组(BMI为18.5～23.9),超重组(BMI为24.0～27.9)和肥胖组(BMI≥28.0)。统计了505名青年学生和993名父母的BMI结果 男女学生超重肥胖者,其父母中单方也患有超重肥胖的比率从20.0％到50.0％,父母双方均患有超重肥胖的比率从6.7％到10.0％ 青年学生与其父母相比,超重肥胖率有显著性差异,女学生父母明显高于女学生,P<0.01;男学生父母也明显高于男学生,P分别小于0.01和0.05。在BMI<18.5组中,女学生明显高于父母,男学生高于其父亲,P<0.01。男女学生的父母亲比较,以及城乡比较,超重率和肥胖率无显著性差异。结论 男女学生超重肥胖者,其父母中单方也患有超重肥胖的比率平均约为30.0%,父母双方均患有超重肥胖的比率平均约为8.0%,从而证明超重和肥胖与遗传有关。但从超重和肥胖的现患率男女学生的父母亲明显高于男女学生这一事实,其差异的显著性表明,环境等因素在超重和肥胖形成中的作用可能更重要,因此,大多数超重和肥胖是可预防的。
OBJECTIVE To observe the relation of BMI between young students and their parents, the relation of heredity, environment and corpulence can be revealed and the results could do some helps to prevent the overweight and obesity. METHODS According to the criterion of Meta - analysis Group of china obesity Task Force, 505 students and their 993 parents were divided into some groups, underweight (BMI <18. 5). normal (BMI, 18.5 - 23. 9), overweight (BMI, 24-27.9), obesity (BMI 5s 28) Result: If the young students (male or female) are overweight of obesity, the percentages that one of the parents is overweight or obesity are about20. 0% - 50. 0% and both of the parents are overweight or obesity are about 6. 7% - 10. 0% . The difference is obvious. For young people, the ratio of overweight is lower than their parents (female, P <0. 01; male, P <0. 05). In the group of BMI <I8. 5. the number of the girl students is larger than their parents and so are the boy students. P <0. 01. There are no difference between their parents (boys and girls) and no difference between city and countryside. CONCLUSION In young corpulent students( male or female), the probability that one of their parents is overweight or obesity is about30. 0% and both of their parents are corpulent is nearly8. 0% . Therefore, our investigation indicates that fatness is associated with heredity. The fact that fatness of young students is lower than their parents also indicates that surroundings play an important role in overweight. Our investigation comes to the conclusion that overweight and obesity can be prevented.
