Analysis on overweight and obesity status and its influencing factors among community elderly people in Jinan city
Objective To analyze the overweight and obesity status and its influencing factors among the community eld-erly people in Jinan city,so as to provide scientific basis in conducting health interventions for the elderly.Methods From January to May 2023,a stratified random sampling method was used to select 732 elderly people aged 60 years or ol-der from communities in 6 administrative districts in the main urban area of Jinan city in 2023,and a questionnaire survey was conducted to collect information on demographic characteristics(including name,age,gender,height,body mass,liter-acy,occupation,per capita monthly household income,and whether or not they suffer from a chronic disease),living habits(including smoking,alcohol consumption,dietary habits,physical activity,sedentary time and sleep time).The body mass index(BMI)was calculated from height and body mass,and the influencing factors of overweight and obesity were ana-lyzed by logistic regression model.Results The BMI median of elderly people in Jinan city was 25.10 kg/m2,in which 24.78 kg/m2 for men and 25.39kg/m2 for women.The BMI median of the younger elderly was 25.09 kg/m2,and that of the older elderly was 26.13 kg/m2.The BMI of 70.31％(502/714)of older adults was in the abnormal range,with a ema-ciation rate of 1.96％(14/714),an overweight rate of 48.32％(345/714),and an obesity rate of 20.03％(143/714).Multi-factor logistic regression analysis showed that illit-eracy or semi-illiteracy(OR=2.821,95％CI:1.095-7.264),primary school(OR=5.529,95％CI:2.197-13.917),senior high school,technical secondary school and technical school(OR=3.080,95％CI:1.466)had a higher risk of being overweight than that of junior college or above(all P＜0.05).Also,the risk of obesity in elderly men was lower than that in women(OR=0.332,95％CI:0.175-0.632,P＜0.05).Primary school(OR=3.699,95％CI:1.167-11.721),chronic diseases(OR=2.899,95％CI:1.595-5.269),sugar addiction(OR=1.965,95％CI:1.038-3.729),meat-based diet(OR=18.906,95％CI:1.528-233.852)were risk factors for obesity in the elderly(all P＜0.05).Farmers and production personnel(OR=0.397,95％CI=0.189-0.836),low level of physical activity(OR=0.313,95％CI=0.132-0.742),sitting time≤3 h(OR=0.368,95％CI:0.140-0.972),sleeping time＜6 h(OR=0.198,95％CI:0.059-0.669)and sleeping time 6-9 hours(OR=0.151,95％CI:0.047-0.490)can predict the lower risk of obesity in the elderly(all P＜0.05).Conclu-sion The rates of overweight and obesity are high among the elderly in Jinan community,and gender,education level,oc-cupation,chronic diseases,eating habits,sugar addiction,physical activity level,sleeping time and sitting time are all influ-encing factors of overweight and obesity in the elderly.
