ABSTRACT
Objective:To analyze the correlation between recessive obesity and lifestyle in physical examination population.Methods:A total of 1 026 people with body mass index (BMI) of 18.5<-24.9 kg/m 2 who completed physical examination in the Health Management Center of Affiliated Hospital of Qingdao University from March 1, 2019 to September 31, 2019 were included in this study. Inbody770 body composition analyzer was used to check the percent body fat, and the subjects were divided into recessive obesity group (405 cases) and control group (621 cases) with the results. The results of routine physical examination were compared between the two groups. The data of five dimensions including marital status, education level, income, occupation and dietary habits were obtained with lifestyle questionnaire. The correlation between recessive obesity and lifestyle was analyzed by binary logistic regression. Results:The proportion of women, BMI, total cholesterol, low density lipoprotein cholesterol and waist-hip ratio were significantly higher in the recessive obesity group than those in the control group [65.2% vs 27.1%, (21.83±1.63) vs (21.56±1.74) kg/m2, 4.68 (4.18, 4.22) vs 4.39 (4.13, 4.83) mmol/L, 2.54 (2.08, 3.00) vs 2.24 (2.13, 2.78) mmol/L, 0.87 (0.84, 0.90) vs 0.82 (0.80, 0.86)]; while the systolic blood pressure, albumin and aspartate aminotransferase were significantly lower [(114.99±11.49) vs (118.97±11.84) mmHg (1 mmHg=0.133 kPa), (45.13±2.83) vs (46.37±2.60) g/L, 15 (12, 18) vs 16 (14, 20) U/L] (all P<0.05). Unmarried ( OR=0.200, 95% CI: 0.123-0.325), eating less white meat [occasionally eating, OR=0.565, 95% CI: 0.304-1.053; rarely eating, OR=0.186, 95% CI: 0.094-0.368], eating less spicy food (occasionally eating, OR=0.298, 95% CI: 0.171-0.519; rarely eating, OR=0.828, 95% CI: 0.487-1.408), drinking more water (1 000-2 000 ml/d, OR=0.366, 95%CI: 0.218-0.615; ≥2 000 ml/d, OR=0.176, 95% CI: 0.087-0.356) were negatively correlated with the occurrence of recessive obesity (all P<0.05). Eating takeout food frequently ( OR=4.639, 95% CI: 2.412-8.923), eating too much edible oil ( OR=10.900, 95% CI: 4.376-27.148), drinking beer ( OR=3.702, 95% CI: 2.290-5.982) and infrequent physical exercise (occasional, OR=13.417, 95% CI: 6.907-26.066; rarely, OR=28.290, 95% CI: 13.532-59.142) were positively correlated with the occurrence of recessive obesity (all P<0.05). Conclusions:There is a correlation between recessive obesity and the lifestyle in physical examination population. Attention should be paid to control the intake of white meat, spicy food, edible oil and beer, ensure the amount of drinking water, reduce the frequency of takeout food, and increase physical exercise to prevent recessive obesity.
