Outline
To analyze the impact of BMI on the prevalence of chronic diseases among adult residents and provide theoretical reference for early prevention of chronic diseases.
A multi-stage stratified random sampling method was used to select residents in Shandong for questionnaire surveys. The questionnaire included basic information, quality of life, and chronic disease prevalence. The propensity score matching method was employed to examine the effect of BMI on chronic disease prevalence.
A total of 2 451 adult residents in Shandong were surveyed. When BMI < 18.5 kg/m2, the impact of BMI on chronic disease prevalence was not statistically significant (P > 0.05). When BMI ≥ 24.0 kg/m2, the average treatment effects of BMI on chronic disease prevalence were -0.134, -0.110, and -0.113 (P < 0.05), increasing the probability of chronic diseases by 11.0%-13.4%. The balance test showed that the standard errors of all variables decreased, and no covariates were statistically significant after matching (P > 0.05). The common support test indicated that both the treatment and control groups were within the common range and relatively symmetric, with almost no systematic differences after matching, demonstrating good matching quality.
BMI ≥ 24.0 kg/m2 increases the probability of chronic diseases among residents. It is necessary to strengthen weight management and public awareness campaigns, expand coverage for key populations, clarify intergroup differences, and propose targeted health management strategies. The roles of the government, primary healthcare institutions, and family doctors should be fully utilized to improve chronic disease prevention and management, thereby enhancing residents’ quality of life.
