| Objective:Investigating the prevalence of obesity among adults aged 15 and over in rural areas of Guangxi in 9 districts and counties,to explore the characteristics of obesity prevalence and its influencing factors,and to provide reference for obesity prevention and control.Methods:The multi-stage stratified random sampling method were used to extract a representative sample tribe of 17558 residents(residence time>6 months)aged 15 years old and above resident from 9 areas in Guangxi:Guiping City,Qinzhou City,Qinzhou City,Linbin City Xingbin District,Yuzhou City,Yuzhou District,Nanning City,Yongning District,Hechi City,Bama County,Guilin Yongfu County,Liuzhou City,Liujiang County,Wuming County.The questionnaire investigation and body measurement were conducted to collect relevant data.Aanalysising the influencing factors of obesity and prevention and treatment.Results:A total of 17558 residents involved in the investigation in all 9 districts and counties.Excluding material incomplete,the data unreasonable a total of 1720,and 15838 of them completed the survey.Among whom aged 15-24 years were 1186(7.49%),aged 25-34 years were 2679(16.92%),aged 35-44 years old were

is the residents of Yongfu County(2.62%).The highest prevalence of obesity is Guiping City(4.16%),the lowest is Yongfu County(2.55%)in male,The highest female is Liujiang County(8.72%),the lowest is Yongfu County(2.68%)in female.(Table 9)⑥Multivariating Logistic stepwise regression revealed that obesity was positively correlated with waist circumference(OR=3.852,95%CI:2.966～5.002)、female(OR=13.416,95%CI:9.997～18.006)、visceral fat rate(OR=1.704,95%CI:1.648～1.762)、smoking(OR=1.650,95%CI:1.217～2.237),drinking(OR=1.693,95%CI:1.275～2.246)、obesity family history(OR=3.622,95%CI:2.446～5.364)and mean SBP(OR=1.010,95%CI:1.005～1.016),overweight and obesity people increased the risk of hypertension by 1.613 times(OR=1.613,95%CI:1.39～1.867)and 2.573 times OR=2.573,95%CI:2.11～3.131).(Table 11、Table 12)Conclusion:The prevalence of obesity among rural residents in GuangXi 9 counties was 4.49%,3.61%in male while 5.28%in female.The prevalence of obesity in the area was positive related to WC、female、visceral fat rate、smoking、drinking、obesity family history and mean SBP.The risk of hypertension were increased by 1.613 times and 2.573 times in overweight and obesity. |
