According to sufficiently reported outcomes , social capital interventions showed mixed effects on quality of life , well-being and self-perceived health and were generally ineffective on loneliness , mood and mortality .
Conclusions Our review highlights the lack of evidence and the diversity among trials , while supporting the potential of social capital interventions to reach comprehensive health effects in older adults
Background Observational studies show that social capital is a protective health factor .
Therefore , we aim to assess the currently unclear health impact of social capital interventions targeting older adults .
Social capital and health: Does egalitarianism matter? A literature review
The aim of the paper is to critically review the notion of  social capital  and review empirical literature on the association between social capital and health across countries . The methodology used for the review includes a systematic search on electronic data bases for peer- review ed published literature . We categorize studies according to level of analysis ( single and multilevel ) and examine whether studies reveal a significant health impact of individual and area level social capital . We compare the study conclusions according to the country 's degrees of economic egalitarianism . Regardless of study design , our findings indicate that a positive association ( fixed effect ) exists between social capital and better health irrespective of countries degree of egalitarianism . However , we find that the between-area variance ( r and om effect ) in health tends to be lower in more egalitarian countries than in less egalitarian countries . Our tentative conclusion is that an association between social capital and health at the individual level is robust with respect to the degree of egalitarianism within a country . Area level or context ual social capital may be less salient in egalitarian countries in explaining health differences across places
