摘要
我国肥胖率呈迅速增长的态势。为控制农村肥胖趋势,开发健康农村人力资本,促进乡村振兴,本文利用2015年中国综合社会调查数据,从热量平衡的角度构建农村肥胖居民蔬果摄入和身体锻炼频率对个人体质指数影响的理论模型。采用两阶段最小二乘法(2SLS)研究发现,肥胖村民蔬果摄入频率越高或者身体锻炼频率越高,越有助于减少肥胖率。一般情况下,肥胖村民每月几次、每星期几次、每天地食用新鲜蔬果,其体质指数(BMI)可分别平均下降3.05、4.07和5.78;每月1次或更少、每月几次、每星期几次、每天地参与锻炼身体,其体质指数可分别平均下降1.96、2.03、2.23和2.55。根据肥胖村民身体锻炼不足的实际,有关部门除了膳食引导外,还要对公众进行更多的体育锻炼教育。
The obesity rate is increasing rapidly in China. In order to control obesity in rural areas, to develop healthy rural human capital and to promote rural revitalization, a theoretical model of the impact of obese rural residents' frequency of vegetables and fruit intake and physical exercise on Body Mass Index (BMI) was constructed from the perspective of heat balance by using the Chinese General Social Survey in 2015. Using two-stage least square method (2SLS), it is found that the higher frequency of vegetables and fruit eating or the higher frequency of physical exercise was done by obese villagers, the better weight loss effect was taken. In general, if obese villagers ate fresh fruit and vegetables by several times a month, several times a week and every day, their BMI would decline by 3.05, 4.07 and 5.78 on average. If they took physical exercise by one or fewer times per month, several times per month, several times per week and every day, their BMI would drop by 1.96, 2.03, 2.23 and 2.55 on average. It was the fact that obese villagers didn't have enough physical exercise. Apart from the dietary guidance, the government should provide more physical exercise education for the public.
