Abstract P337: Social Network Size is Associated With Healthy Lifestyle Factors: Results From the Hispanic Community Health Study/Study of Latinos (HCHS/SOL)
Background: Social ties within social networks have been shown to influence healthy lifestyles. However, little is known about the association among size of familial social networks, social network dynamics (such as frequency of contact and perceived connectedness), and healthy lifestyle factors in Hispanic/Latino adults. We examined cross-sectional associations of central family social network size, as well as frequency of contact with central family members (children, parents, in-laws) and perceived connectedness to extended family members (uncles, aunts, and other relatives), with individual healthy lifestyle factors.
Methods: Data were analyzed from 15,511 self-identified Hispanic/Latino adults ages 18-74 years from the Hispanic Community Health Study/Study of Latinos (HCHS/SOL). Size of central family, frequency of contact with central family members in past 2 weeks, and perceived connectedness to extended family, were categorized into approximate tertiles based on the distribution of the data. Healthy lifestyle factors included alcohol use (men <30g/day; women <15g/day), not currently smoking, body mass index [BMI] 18.5 to <25.0 kg/m2, physical activity in the highest sex-specific 40%, and healthy diet in the highest sex-specific 40%. Survey logistic regression was used to compute odds ratios [OR] and 95% confidence intervals [CI], with models adjusted for age, sex, education, income, Hispanic/Latino background, employment status, religion, church attendance, marital status, acculturation, and language preference.
Results: Compared to participants with a central family social network of 0-3 individuals, those with a family social network of 4-5 members were significantly less likely to have a healthy diet (OR: 0.86; 95% CI: 0.74, 0.99) or a healthy BMI (OR: 0.74; 95% CI: 0.65, 0.85). Also, those with 6-11 members were also significantly less likely to have a healthy BMI (OR: 0.58; 95% CI: 0.49, 0.69). Individuals reporting frequent contact with 3-4 and 5-11 family members were less likely to have a healthy BMI (OR: 0.76; 95% CI: 0.66, 0.87; OR: 0.60; 95% CI: 0.51, 0.72; respectively) versus those reporting frequent contact with only 0-2 family members. However, individuals who reported feeling connected to 3-5 extended family members were more likely to have a healthy diet (OR: 1.16; 95% CI: 1.00, 1.36) and healthy BMI (OR: 1.15; 95% CI: 1.00, 1.33), and those who felt connected to 6-7 extended family members were more likely to be non-smokers and to have a healthy BMI (OR: 1.16; 95% CI: 1.00, 1.34; OR: 1.20, 95% CI: 1.20; 95% CI: 1.04, 1.38; respectively) versus those who reported feeling connected to 0-2 extended family members.
Conclusions: These findings suggest that social network size and dynamics may play an important role in influencing healthy lifestyle factors among Hispanic/Latino adults. Further, specific influences may differ based on the type of relationship.
