Background
As the world’s most populous country, China has a very large group of elderly population. According to data from the Seventh National Census, in 2020, the total number of people aged 65 and above in China was about 191 million, accounting for about 13.5% of the total population [
1]. Because of urbanization and industrialization, large-scale population migration movements have emerged in China since the last century [
2]. In China, there were 376 million internal migrants whose homes were not the locations of household registration (hukou) in 2020, with 249 million of them moving from rural to urban areas and 127 million from urban to urban areas, respectively [
3]. Driven by the rapid development of aging, the number of migrant elderly people in China increased year by year [
4]. The 2018 report on China’s migrant population development showed that the number of Chinese migrant elderly increased from 5.03 million in 2000 to 13.04 million in 2015 [
5]. Most Chinese elderly migrants move to cities where their children live to provide care for their grandchildren [
6]. In the current study, these elderly are referred to as the migrant older adults with children (MOAC) [
7]. In general social and cultural norms, women are primarily responsible for childcare and other family responsibilities [
8], while most grandchild care is also provided by grandmothers in current Chinese family [
9,
10], which result in more women than men among the migrant elderly in China [
11].
Loneliness has become a common problem among older people worldwide [
12]. J de Jong-Gierveld’s understanding of loneliness emphasized more on subjective feelings, and considered loneliness as an unpleasant emotional experience resulting from the perception of social isolation or lack of contact with others [
13]. Peplau et al. consider loneliness as subjective social isolation, an unpleasant experience that arises when there is a discrepancy between an individual’s desired social relationships and the reality [
14]. A study in Anhui, China showed that 78.1% of older people had moderate to severe levels of loneliness [
15]. In a study among Finland’s elderly, about 39% of the older people felt lonely [
16]. Factors associated with loneliness in older adults, such as sociodemographic characteristics [
17,
18], social participation [
19], social support [
20], smoking [
21], and physical exercise [
22] were identified in some studies. Concerning the female elderly, about half of the Indonesian older women always felt lonely [
23]. Widowhood, depression, mobility problems, and mobility reduction increased the risk of loneliness among older women in Sweden [
24]. Several studies also showed that the female elderly reported higher levels of loneliness than males [
25,
26]. Although there are more studies on loneliness among the older people, little attention has been paid to the loneliness of female migrant older adults in China.
Social integration is defined as participation in a wide range of social relationships [
27], which is an essential element of health [
28] and is considered to be related to loneliness for older people [
29]. A study in Korea showed that the migrant elderly with better social integration had lower levels of loneliness [
30]. A study on internal migrant workers in China found that the social integration of migrant workers was significantly and negatively related to loneliness [
31]. Santini’s study on older Americans showed that when older adults were more socially disconnected, they perceived higher levels of loneliness [
32]. Jang et. al’s study on Korean American older immigrants found that social integration was negatively related to loneliness [
30]. Many studies have examined the social integration of migrant populations, but there is still a lack of attention to the social integration of female migrant older adults, with some studies in China mainly focusing on their health status [
33‐
35].
Social support comes from people’s social needs, and typically refers to services, care, or encouragement provided by members of social networks [
36]. Previous studies have shown that social support was negatively related to loneliness [
37‐
39]. Among Chinese older adults, social support from family or friends could help alleviate their loneliness [
39]. Wong and Leung’s study showed that social support had a positive impact on the mental health of Chinese female migrants [
40], however, the study did not further explore the relationship between social support and other factors, such as social integration. A study of Muslim elderly in Turkey suggested that perceived social support was an important factor influencing loneliness in older adults [
38].
Social integration and social support are both important and unique aspects of social relationships. Social integration referred to the principle of how individuals related to each other at the society level, and also reflected the connection between the individual and society, the community or other units [
41]. Social support, on the other hand, emphasizes the real or perceived help and support that individuals receive from their social networks in difficult times [
42]. Social integration mainly focused on interpersonal interactions within the background of social structures, and transferring individual characteristics and behaviors to the environment or group. For example, the community, which is an important environment for people’s social integration. While social support was mostly still a concept at the individual level, focusing on interpersonal interactions only [
43,
44]. There was little research on the relationship between social support and social integration, although social support and social integration could jointly influence an individual’s health [
45,
46]. A study showed that when the old adults’ social networks were limited, the level of social support generally decreased [
47].
In summary, previous studies had explored the effect of social integration on loneliness, as well as the effect of social support on loneliness, yet none study clarified the relationship between social integration, social support, and loneliness simultaneously, not mention among the female MOAC. Thus, this study aimed to clarify the association between social integration and loneliness and the mediating role of social support between them among the female MOAC in Jinan, China.
