Socioeconomic Status and Theories of Health Behavior

Social factors influence health behaviors and health outcomes. Individual behaviors can significantly impact health but are shaped by social determinants such as education, income, and occupation. People from disadvantaged backgrounds tend to engage in less healthy behaviors (smoking, unhealthy diet, physical inactivity) and experience poorer health outcomes (higher mortality, chronic diseases). Social differences explain a substantial portion of this gap. This chapter explores how theories of health behavior can be instrumental in understanding and potentially alleviating these social differences in health behaviors. It examines how major health behavior theories integrate social factors. Social-cognitive theories propose that social cognitions (attitudes, beliefs, norms) influence health behaviors. Social background can shape these cognitions, potentially explaining social differences. However, the evidence for this mediation is mixed, and moderating effects of social factors have increasingly been observed as well. Stage theories suggest individuals progress through stages of behavior change (precontemplation, action, maintenance). Social status might influence the stage someone occupies, but research on this is limited. Dual-system theories propose both reflective (intentional) and non-reflective (habitual) pathways to behavior. Social factors can influence both systems. For example, socioeconomic deprivation might lead to a focus on short-term benefits, impacting temporal valuations. Additionally, limited resources can deplete self-control, making individuals more susceptible to unhealthy impulses. In addition, environmental factors have an important role in shaping behavior. Social stratification can lead to unequal access to resources and exposure to cues that influence health behaviors. Interventions to change health behaviors that rely on behavioral determinants, thus, have the potential to inadvertently increase existing differences in health behaviors and health outcomes. Understanding how social factors influence health behaviors is crucial for designing effective interventions. By considering the social determinants of health and incorporating them into behavioral theories, strategies to reduce social inequalities in health outcomes can be developed.
