作为群体现象的独生子女(1976-2001)超重及肥胖问题研究

A Study of Only-Children's Overweight and Obesity Problem(1976-2001)

以1976-2001年出生的独生子女为主要研究对象,从体质指数出发,探索独生子女群体的健康受损可能性。研究发现独生子女群体体重过轻、超重及肥胖比例高于非独生子女,其中青少年群体与中年群体的独生子女超重及肥胖比例(分别为14. 2%、25. 6%)与同出生组非独生子女差异最显著(分别为7. 9%、20. 1%)。BMI指数随年龄增长,且独生子女高于非独生子女,尤其在青少年时期与中年时期,第一代独生子女目前承受最高的健康风险。在对超重及肥胖的影响因素分析中,发现:在年龄、受教育程度的共同影响下,整体趋势而言,不同文化程度、不同年龄段群体中独生子女超重及肥胖可能性高于非独生子女;独生子女群体内部整体呈现出受教育程度越高,超重及肥胖比例可能性越低于同龄群体;虽然超重及肥胖的可能性随年龄增长,但是非独生子女群体在中年阶段这一可能性开始呈现缓慢走低趋势,而独生子女群体除高文化程度群体外,均为持续上升趋势;第一代独生子女中高文化程度人群超重及肥胖可能性表现最突出,需要引起注意及干预。考虑到独生子女目前在我国总人口中的比重,这一群体的体重问题及其表现出的趋势可能是非常重要的公共卫生潜在危机,而其背后的深层原因需要进行更深入的研究。

Based on physical fitness index,this study researches into the possibility of health problem suffered by the only-children group born between 1976 and 2001.Our findings are as follows:The proportion of underweight,overweight and obesity in only-children's,group is higher than the non-only-children group,among whie.h the percentage of overweight and obesity in teenager and middle-age group(14.2%and25.6%respectively)is most significantly higher than the non-only-children group(7.9%and 20.1%respectively).BMI increases with age,and is higher among only-children.Also,the first generation only-children in teenager and middle age periods suffer from highest health hazard.In the factor analysis of overweight and obesity,our findings are as following:on the whole,under the influence of age and education,the proportion of overweight and obese only-children is higher than non-only-chil-dren across different educational and age groups;among the Only-children at the same age group,the higher the educational level',the lower the possibiiity of overweight and obesity;although the probability of overweight and obesity increases with age,it slows down during the middle-age period for non-only-children.Yet for only-children,this rising trend continues except for those with higher educational level;the first generation only-children of high educa-tion level are most likely to be overweight or obese,which deserves special attention or even intervention.Considering the percentage of only-children in our population,the group's weight problem and future trend could be very a very prominent potential hazard for public health,while the underlying causes need more in-depth research to reveal.
