Abstract:Objective To study the influencing factors of chronic diseases among the elderly so as to provide effective advice and measures for their chronic disease prevention and treatment. Methods We sorted the data from the Fifth Health Service Survey in Heilongjiang Province, and then selected the elderly aged 60 years and above to serve as the research subjects. The influencing factors were divided into five dimensions, namely health behavior, physical function, interpersonal network, material condition and social support. Statistical analysis was performed by partial least squares structural equation modeling (PLS- SEM). Results The prevalence rate of chronic diseases in the research subjects was 56.52%. The composite reliability estimates of the measurement models were all more than 0.8, meaning the reliability of the data was good. The estimates of the factor loadings were between 0.56-0.89, showing the models were acceptable. The average variance extracted (AVE) values were more than 0.5, indicating latent variables could be well explained by the observation variables. Health behavior, physical function, material condition and social support were all negatively correlated with the occurrence of chronic diseases. The path coefficients of health behavior with chronic diseases, physical function with chronic diseases, material condition with chronic diseases, and social support with chronic diseases were -0.395, -0.306, -0.340 and -0.244 respectively. Conclusions Health behavior, physical function, material condition and social support have direct effects on chronic diseases; meanwhile, they interact with interpersonal network to build a complex path and generate the synthetic action on the chronic diseases. Among them, health behavior is the primary factor influencing chronic diseases, and the formation of health behavior is conducive to controlling the occurrence and development of chronic diseases. Degradation of body function of the elderly increases the risk of chronic diseases, but improvement of material condition and social support is helpful for lowering the prevalence rate of chronic diseases and promoting the quality of life in the elderly with chronic diseases.
