To the best of our knowledge, this is the first study to explore the association between HCBSs utilization and depressive symptoms among Chinese older adults using nationally representative survey data. Moreover, this study assessed the effects of individual- and provincial-level covariates on depressive symptoms among older adults. Results showed that older adults who utilized HCBSs were less likely to suffer from depressive symptoms, even after adjusting for sociodemographic characteristics, health status, lifestyle, and province-level covariates.
In the early 1980s, in the United States and Denmark, HCBSs provision systems were first established to match the demands of older adults[15, 35]. In China, the implementation of HCBSs occurred later than that in Western countries. However, since 2008, a series of policies have been implemented to not only encourage the provision of HCBSs at the national level, but also promote healthy ageing[19, 36, 37]. Due to the implementation and rapid promotion of national policies, the provision of HCBSs has increased dramatically from 26.10–62.01% in China[38]. However, the utilization rate of HCBSs was still low compared with the provision rate of HCBSs in China. This may be due to the large provision of HCBSs in the community resulting in an increase in the utilization rate; however, the provision of HCBSs cannot precisely match the demand of HCBSs for older adults, which causes the utilization rate to remain low.
The prevalence of depressive symptoms in older adults aged 60 years and above was 36.7% in 2018, which was significantly higher than that in 2015[5], despite the same measurement and cut-off points being used. In traditional Chinese society, positive family relations are beneficial to mental health and act as a social security system for older adults[39]. However, rapid industrialization and urbanization have shifted these traditional arrangements. Nowadays, older adults are less likely to live with younger generations and receive advice from them. This has direct implications on access to social care and financial security and even affects the mental health of older adults[40, 41].
The present study found that gender, marital status, educational level, residence, number of chronic diseases, SRH, and smoking might be associated with depressive symptoms, which is also in agreement with previous researches. Male participants had a lower risk of depressive symptoms compared to female participants[42]. Furthermore, older adults living with a partner were found to have a lower risk of depressive symptoms compared to older adults who were single[43]. Notably, older adults with higher educational levels[44], and living in urban areas[45] had a lower risk of depressive symptoms. Chronic diseases, in contrast, were found to increase the risk for depressive symptoms [46]. Finally, older adults with better self-rated health [47], and who were not smoking [48] had a reduced risk of depressive symptoms. Provincial factor (GDP per capita) was also found to be important factor influencing depressive symptoms in older adults in the present study, which is consistent with previous studies on the influence of provincial factors on health in older adults [49].
In other countries, the relationship between HCBSs and depressive symptoms has also been explored. As reported by one study from the United States, the utilization of outdoor HCBSs, such as church programs, transportation, and senior centers was associated with depressive symptoms, whereas the utilization of indoor HCBSs, such as home visits, personal care, and shopping assistance, was not associated with depressive symptoms[50]. Another study indicated that depressed older adults were more likely to utilize HCBSs than non-depressed older adults, which also confirmed that HCBSs will play a role in alleviating depressive symptoms in older adults[51]. In addition, a study in Germany indicated that services, such as daily care and health care, were significantly associated with depressive symptoms[52]. Finally, this study confirmed the HCBSs utilization to be a protective factor against depressive symptoms in older adults. While vigorously improving the provision of HCBSs, we should also pay attention to utilization of HCBSs to promote healthy aging.
Our findings support the hypothesis that HCBSs utilization has a positive effect on depressive symptoms in the aging population in China. First, the family’s ability to provide elderly care has been reduced following demographic shifts and socioeconomic changes[53], and older adults may feel a sense of loneliness or disappointment if they fail to receive care from their children[54]. However, the daily care services of HCBSs, such as day care centers, nursing homes, senior dining tables, etc., could be an alternative to accompanying children, reduce feelings of loneliness and marginalization, and protect older adults from depressive symptoms. Second, HCBSs include not only daily care services, but also health care services, such as regular physical examinations, onsite visits, family beds, community nursing, and health management, which are significant approaches to promote somatic symptoms and alleviate depressive symptoms in older adults to a certain extent[55]. Moreover, participation in the entertainment of HCBSs, such as Tai Chi, Table Tennis, and Mahjong, could provide an opportunity to interact with others and reduce negative affect among older adults who are alone at home[56], which is an essential protecting factor against depressive symptoms. Thus, providing targeted HCBSs at the community level could satisfy unmet elderly care needs and may reduce the incidence of adverse emotions and consequently lower the risk of depressive symptoms.
