| Abstract | Acculturation has emerged as an independent risk factor for different health practices across immigrant groups. Prompted by evidence of increasing melanoma incidence among Latinos, the present research investigated the impact of acculturation on Latinos’ sun safety. Data from 496 Latino respondents to the 2005 Health Information National Trends Survey were analyzed with multiple linear regression and structural equation models. Sunscreen use, seeking shade and wearing protective clothing were the primary outcomes, assessed by frequency scales. Acculturation was the primary predictor, assessed by a composite index. The direct, mediated, and moderated effects of acculturation on sun-safe behaviors were investigated in three studies. Hypothesized mediators included health status, education, and social networks; hypothesized moderators included gender, age, region, and health insurance status.; In adjusted models in Study 1, increased acculturation was associated with decreased use of shade or protective clothing when outdoors (all p<0.05), across gender and region of residence. In the mediation models in Study 2, education level emerged as a potential mediator for sunscreen use and wearing protective clothing (both p<0.05). Perceived physical health status and social networks involvement showed mediating effects only for sunscreen use (p<0.05). The results of the moderated mediation analyses in Study 3 revealed that the effect of education as a mediator between acculturation and sunscreen use might be moderated by gender, with the association between education and sunscreen use being stronger among women than men (p<0.08). Also, there was evidence that the association between acculturation and social networks was stronger among insured than uninsured Latinos (p<0.08).; Despite data limitations, the findings demonstrated that acculturation has adverse effects on skin cancer risk-related practices and suggested mechanisms through which acculturation might impact different sun-safe behaviors. Regarding interventions, initiatives for low-acculturated Latinos could reinforce existing sun-safe behaviors via informal, Spanish-language strategies; initiatives for high-acculturated Latinos might require more resources due to the need for behavior modification. The mediation and moderated mediation analyses have descriptive importance and could inform intervention development as well as studies on causality. The results of this research should be replicated with large Latino samples and longitudinal datasets, encompassing a variety of psychosocial measures. |
