ソーシャル・キャピタル
A growing body of research has found that the presence of social capital through social networks and communities has a protective quality on health. Social capital affects health risk behavior in the sense that individuals who are embedded in a network or community rich in support, social trust, information, and norms, have resources that help achieve health goals. For example, a person who is sick with cancer may receive information, money, or moral support he or she needs to endure treatment and recover. Social capital also encourages social trust and membership. These factors can discourage individuals from engaging in risky health behaviors such as smoking and binge drinking.
