Impact Of Household Income And Lifestyle On Chinese Adult Obesity

Objective By studying the prevalence trend of BMI(body mass index)overweight/obesity and abdominal obesity in China from 2000 to 2015,and exploring the influencing factors of BMI overweight/obesity and abdominal obesity from two dimensions of family income and life style,some suggestions should been provided for the prevention of BMI overweight/obesity and abdominal obesity,the promotion of public health and the reduction of chronic diseases.Methods In this study,the data from CHNS(China Health and Nutrition Survey)is select 2077 adult related data in 2000,2004,2006,2009,2011 and 2015.All the data are collected and analysed with sofeware Stata14.0 and SPSS 20.0.The indications of BMI overweight/obesity and abdominal obesity are measured by BMI(body mass index)and WC(Waist Circumference)respectively;the research indicator is selected in family income is the per capita income of the family,and the prices are calculated according to 2015;the research indicators selected in lifestyle are the daily living habits(whether to drink tea,whether to drink coffee,whether to smoke,whether to drink),eating preferences(snacks,fast food,fruits,vegetables,sugar drinks preferences),exercise(exercise intensity)and daily commuting (whether walking,whether taking the bus/subway,driving/taking a taxi or not),the confounding factors that may affect BMI overweight/obesity and abdominal obesity of Chinese adults are controlled,such as age,gender,education level,marital status,residence,etc,and logistic regression is used to analyze the influence of family income and lifestyle on BMI overweight/obesity and abdominal obesity in Chinese adults,and the results are verified by probit model and robustness.Results (1)The number of BMI overweight/obesity and abdominal obesity are 117 and 723 respectively among 2077 adults in China.The rate of BMI overweight/obesity and abdominal obesity are5.53%and 34.81%,respectively.The situation is grim and high;(2)The average BMI and WC of women in China are slightly higher than that of men.The average BMI and WC of young people are slightly higher than that of middle-aged and old people.The average BMI and WC increase with the increase of education level.The overall rate of overweight/obesity of women is slightly higher than that of men,and the rate of abdominal obesity of men is slightly higher than that of women;(3)The results of logistic regression after controlling confounding factors shows that the per capita family income have no significant effect on BMI overweight/obesity and abdominal obesity;tea drinking and smoking are the risk factors of BMI overweight and obesity,and the risk of BMI overweight/obesity in tea drinking and smoking group are 1.59 and 1.62 times than that in non tea drinking and smoking group; drinking tea,alcohol and fast food preference are the risk factors of abdominal obesity,the risk of abdominal obesity for those who drinking tea or alcohol are 1.59 times and 1.60 times than those who do not,and the risk of abdominal obesity for those who preferred fast food is 1.53 times than those who do not like;exercise is the protective factor of BMI overweight/obesity and abdominal obesity for adults in China,and the risk of BMI overweight/obesity and abdominal obesity for those who exercised moderately is 0.56times and 0.76 times than those who exercised mildly.The analysis results are verified by proit model which are consistent with the results of logistic regression and the results pass the robustness test.Conclusion Therefore,the relevant departments should prevent BMI overweight/obesity and abdominal obesity from the following aspects.1.Popularize health knowledge,promote health education and health promotion;2.Participate in health actions,promote healthy lifestyle,reasonable diet,scientific sports,and get healthy life;3.Provide health services,provide systematic and continuous prevention,treatment,rehabilitation,health and other integrated services;Fourth,the span of healthy life should been extended and departmental cooperation should been strengthed to improve the healthy life expectancy.
