Abstract:
Objective:To explore the association between socioeconomic status (SES) and overweight/obesity in Yi people in Sichuan province.Methods:A cross-sectional study was conducted in Liangshan Yi Autonomous Prefecture in 2015. Stratified cluster sampling method was used to enroll Yi farmers and rural-to-urban Yi migrants aged 20-80 years. SES was measured by education level, personal annual income, and compound SES index. Unconditional logistic regression models were used to determine the association between SES and overweight/obesity (BMI≥24.0 kg/m 2). Results:1 894 Yi farmers and 1 162 rural-to urban migrants were included in the analysis. After adjustment for age, smoking, drinking and physical activity, compared with illiteracy, OR for farmer males with higher education level (primary or junior school, senior high school or higher) were 1.71 (95 %CI: 1.13-2.58) and 4.15 (95 %CI: 2.10-8.22). Compared with lower income group (<5 000 CNY/y), the higher income group had increased risk ( OR=1.66, 95 %CI: 1.12-2.44). For farmer males with medium and high SES level, the risk of overweight/obesity were 1.65 (95 %CI: 1.02-2.67) and 3.26 (95 %CI: 1.97-5.42) compared with low level of SES. For farmer females, the risk increased with the higher income, with OR as 1.49 (95 %CI: 1.10-2.02). Compared with low SES level, farmer females with medium level of SES was associated with 1.47 (95 %CI: 1.11-1.95) times higher risk of overweight/obesity. In Yi migrants, the association between SES and overweight/obesity was not found. Conclusion:Socioeconomic status was positively associated with overweight/obesity only in Yi farmers.
