自評健康與社會資本：以國際社會調查計畫資料為本的跨國分析

Objectives: The impact of social capital on health is increasingly discussed. Many studies have highlighted the health benefits of social capital. However, most research results are affected by limitations. Failure to clarify the exogenous nature of social capital and the cross-contextual effects of social capital may limit the inferences of other research. Therefore, in this study, largescale multinational data are used to analyze the effect of individual social capital on health in various informal and formal social resource conditions. Methods: Data came from International Social Surveys, which are collected by dozens of national survey agencies worldwide. Data from the 2007 leisure life group and the 2017 network group were used for analysis. Results: Individual social trust and social participation are positively linked to health, and social participation has a more positive effect on health in countries with high social capital or in Organisation for Economic Co-operation and Development (OECD) countries. In countries with high levels of social capital, social trust exerts an additional positive effect on health, but this does not occur in OECD countries. Conclusions: This finding facilitates the reevaluation of how social capital affects health and how its effects depend on social conditions.
