Multimorbidity and Mental Health: The Role of Gender among Disease Causing Poverty, Rural, Aged Households in China
(1) Background: The association between multimorbidity and mental health is well established. However, the role of gender in different populations remains unclear. Currently, China is facing an increased prevalence of multimorbidity, especially in its disease causing poverty population. The present study explores the gender based differences in the relationship between multimorbidity and mental health using data from the rural, disease causing poverty, older age population in Shandong province, China, as a case study. (2) Methods: The data were obtained from the survey on the health and welfare of disease causing poverty households in rural Shandong province. We identified 936 rural participants who were over 60 years old from disease causing poverty households. The mental health status was measured using the Kessler Psychological Distress Scale (K10) instrument. Using a multivariable linear regression model, including the interaction of gender and multimorbidity, gender differences in the association between multimorbidity and mental health were explored. (3) Results: Multimorbidity was a serious health problem in rural, disease causing poverty, older age households, with the prevalence of multimorbidity estimated as 40% for women and 35.4% for men. There was a strong association between multimorbidity and mental health, which was moderated by gender. Women had higher K10 scores than men, and the mean K10 score was highest in women with three or more chronic diseases. Compared with men, women with multimorbidity had a higher risk of mental health problems. (4) Conclusions: The prevalence of multimorbidity in older age rural disease causing poverty subpopulations is a severe public health problem in China. The association between multimorbidity and mental health differed by gender, where multimorbid women suffered an increased mental health risk compared with men. Gender differences should be addressed when delivering effective physical and mental healthcare support to disease causing poverty, older age, rural households.
