Prevalence of central obesity among the elderly with different body mass indexes in Xuhui District,Shanghai
[Objective]To investigate the prevalence and influencing factors of overweight,obesity and central obesity among elderly residents in Xuhui District,and to analyze the epidemiological status of central obesity in elderly people with different body mass indexes.[Methods]The third round of health status and health service utilization monitoring data in Xuhui District was used.The information collected from questionnaire survey and physical examination were analyzed.SPSS 20.0 software was used for χ2 test,trend χ2 test and multinominal logistic regression analysis.[Results]5 096 survey subjects were included.The prevalence of overweight,general obesity,and central obesity in the residents aged 60 and above in Xuhui District were 34.3%,6.5%,and 29.2%,respectively.There was gender difference in the rates of overweight,obesity,and central obesity among the residents.The overweight and central obesity rates in males were higher than those in females,while the obesity rate was lower than that in females(P<0.05).Multinominal logistic regression analysis showed that in comparison with the normal weight non-central obesity group drinking only at party(OR=1.729,95%CI:1.184‒2.525),and hypertension(OR=1.637,95%CI:1.305‒2.053),were highly associated with normal weight with central obesity.Aged 60‒ years(OR= 1.589,95%CI:1.190‒2.120),aged 70‒ years(OR=1.763,95%CI:1.327‒2.342),male(OR=1.379,95%CI:1.134‒1.676),hypertension(OR=2.231,95%CI:1.878‒2.649),former smokers(OR=1.437,95%CI:1.027‒2.011),drinking at party only(OR=1.491,95%CI:1.107‒2.006),and drinking≥3 times per week(OR=1.611,95%CI:1.116‒2.325),were highly associated with overweight combined with central obesity.Aged 60‒ years(OR=3.817,95%CI:2.251‒6.474),aged 70‒ years(OR=3.084,95%CI:1.838‒5.175),hypertension(OR=3.683,95%CI:2.753‒4.929),diabetes(OR=2.085,95%CI:1.511‒2.878),former smokers(OR=1.835,95%CI:1.043‒3.226),were highly associated with compound obesity.Central obesity was found in the elderly residents with different BMI categories,and the rate of central obesity increased with the increase of BMI grade.[Conclusion]The prevalence of overweight,obesity and central obesity among the elderly aged 60 years and above in Xuhui District is not optimistic.Attention should be paid to the elderly under 80 years old who are with hypertension and/or diabetes,alcohol consumption,low educational level and not doing physical exercise.Especially for the central obesity population with normal BMI,measures should be taken to prevent and intervene the occurrence of obesity and related diseases.
