This study aimed to determine which social network, demographic, and health-indicator variables were able to predict the development of high nutrition risk in Canadian adults at midlife and beyond, using data from the Canadian Longitudinal Study on Aging. Multivariable binomial logistic regression was used to examine the predictors of the development of high nutrition risk at follow-up, 3 years after baseline. At baseline, 35.0 per cent of participants were at high nutrition risk and 42.2 per cent were at high risk at follow-up. Lower levels of social support, lower social participation, depression, and poor self-rated healthy aging were associated with the development of high nutrition risk at follow-up. Individuals showing these factors should be screened proactively for nutrition risk.

As the number of older adults is expected to increase exponentially within the next few decades, loneliness, social isolation, and depression among seniors are growing public health concerns. Although formal treatment options, such as therapy and medication, can be helpful for depression, they can also be expensive and sometimes ineffective. It is therefore important to consider other potential treatment options and social interventions. Alternative methods for addressing mental health issues are especially important for older adults, as they may encounter barriers associated with aging such as limited mobility and decreased social networks. In these circumstances, online social networking may offer a potential “social cure” to alleviate loneliness, social isolation, and depression. The purpose of this scoping review was to gather and summarize the current literature on associations between online social networking and mental health outcomes (e.g., depression, life satisfaction, loneliness) among older adults. An initial search of 3,699 articles resulted in 52 articles that met criteria for inclusion. Five common themes were identified: (1) enhanced communication with family and friends, (2) greater independence and self-efficacy, (3) creation of online communities, (4) positive associations with well-being and life satisfaction, and (5) decreased depressive symptoms. Implications for older adults’ mental health, social connectedness, programs and policies are discussed.

The purpose of this study was to determine the key determinants of loneliness of older Canadians. We drew on the assumptions concerning the importance of person-environment fit to test the relative importance of personal characteristics, deprived living conditions, social network/social engagement, and satisfaction in explaining loneliness. Data comprised a sample of 3,799 respondents over age 65 drawn from Statistics Canada’s General Social Survey, Cycle 22. Personal characteristics, social network size and composition, and satisfaction with network contact were found to be related to loneliness, as were indicators of living in economically and socially challenging conditions. Older adults who had experienced a recent downturn in their financial situation, and who lacked the help needed to cope with a recent personal challenge, reported higher levels of loneliness. A striking feature of our findings is the relatively low scores on loneliness of older Canadians compared to older adults in other countries.

A study ofolder adults in Israel (n = 170) examined the relationship of activity level and social network characteristics to respondents' subjective well-being, controlling for background socio-demographic characteristics and extent of physical disability. Factor analysis derived three activity factors corresponding to formal, informal and solitary activity. A hierarchical regression procedure revealed that physical disability accounted for 40 per cent of the variance in the well-being measure. Extent of informal activity explained another 3 percent of the variance, but was outweighed in the final model by the addition of a social network factor – degree of network supportiveness (R2 =.48). The findings suggest that it is the social network aspect of activity that makes a difference in older persons' subjective well-being, rather than the effect of activity per se.

In this study, Weiss's (1973) theorizing about the sources of emotional and social loneliness is elaborated – with notions about the asymmetric gratifications derived from marriage, about the conflicting loyalties that result from remarriage, and about selection into marriage – in order to reach an understanding of gender differences in loneliness, both in and outside of marriage. First and subsequent marriages are considered, as well as marital disruptions and never marrying. The data (N = 3737) are from the 1992 Dutch survey on older adults' living arrangements and social networks (NESTOR-LSN). Marital-history differences emerge, not only for emotional loneliness, but also (and contrary to Weiss's theoretical conceptualizations) for social loneliness. The marital-history differences in emotional and social loneliness are greater among men than women. For men, the marriage bond appears not only to be more central to emotional well-being than is the case for women but also to play a pivotal role in their involvement with others. Marital history offers the best explanation for differences in emotional loneliness among men, but social embeddedness characteristics also account for differences in emotional loneliness among women. Apparently, whereas men are more likely to find an intimate attachment in marriage, women also find protection from emotional loneliness in other close ties. The marital-history differences in social loneliness are largely mediated by social embeddedness characteristics, partly in different ways for men and women. Involvement in activities outside the home serves as the context for sociability for men, whereas parenthood plays a more important role in women's social engagements.
