Study on the relationship between number of exercise steps and central obesity among elderly residents in Shanxi Province
Objective To investigate the current status of central obesity among elderly residents in Shanxi Province and explore the association between number of exercise steps and central obesity.Methods In 2022,a survey on chronic diseases and their risk factors was conducted among permanent residents of Shanxi Province using a multi-stage stratified random sampling method.A total of 4 710 resident elderly residents(60 years old and above)were selected as the respondents.The x2test was used to analyze the influencing factors of central obesity and logistic regression model to analyze the relationship between number of exercise steps and central obesity.Results The results showed that the prevalence rates of obesity and central obesity were 17.7％and 41.3％,respectively.Number of exercise steps was identified as a impact factor affecting central obesity(P=0.004).Through the analysis of different age groups,after excluding the influence of confounding factors,the exercise step number ≤3 000 group was taken as the comparison group.The prevalence of central obesity decreased by 32.7％,43.8％and 33.9％in the 60-＜70 age group in the 3 000-6 000 steps group,6 000-10 000 steps group,and 10 000 steps and above group,respectively(OR=0.673,95％CI:0.545-0.832,P＜0.001;OR=0.562,95％CI:0.449-0.703,P＜0.001;OR=0.661,95％CI:0.497-0.878,P=0.004).In the 70-＜80 age group,the prevalence of central obesity decreased by 44.6％in the above 10 000 steps group(OR=0.554,95％CI:0.343-0.895,P＜0.001),while there was no statistical significance in other groups(P＞0.05).Conclusions The impact of number of exercise steps on reducing the prevalence of central obesity among elderly people varies by age groups.Targeted intervention measures should be taken.Encourage younger elderly individuals(aged 60-＜70)to maintain a daily number of exercise steps between 6 000 to 10 000.For middle-aged(aged 70-＜80)and older elderly individuals(aged 80 and above),the number of exercise steps should be reasonably controlled under the intensity and frequency of exercise that their physical condition can withstand,so as to improve their physical health level and prevent central obesity.
