Introduction:
Social connectedness (SC) is an important determinant of maintaining overall health, and the strength of connections with others may influence cardiovascular health (CVH) in part through improvement in cardiovascular disease risk factors. However, there is a lack of research on the role of SC in promoting CVH, as defined by the American Heart Association’s 2020 Impact Goals. The objective of this study is to determine the effect of SC on CVH among adults.
Hypothesis:
Higher SC will be associated with higher odds of optimal CVH, relative to inadequate CVH.
Methods:
Data are from the Community of Mine study, a cross-sectional study of 602 participants (42% Hispanic, 56% female, mean age 59 years) living in San Diego County. CVH was based on Life’s Simple 7 using six metrics including smoking, physical activity, body mass index, total cholesterol, blood pressure, and fasting glucose. A 12-point summary score was used to classify participants as having inadequate (0-6), average (7-8), or optimal (9-12) CVH. SC was assessed using a 7-item scale designed to assess social relationships and strength of connections with others (Cronbach’s alpha=0.92). A mean score across all items was generated. Multinomial logistic regression was used to estimate the association between SC and CVH. We adjusted for age, race/ethnicity, governmental cash assistance, income, education, sex, history of medical comorbidities, family history of heart disease, and depressive symptoms.
Results:
SC was independently associated with CVH (p=0.04). More specifically, a 1-unit increase in mean SC score was associated with a 46% increase in relative odds of having optimal CVH compared to inadequate CVH (OR=1.46, 95% CI: 1.07-1.98), and a 21% increase in relative odds of having average CVH compared to inadequate CVH (OR=1.21, 95% CI: 0.96-1.52).
Conclusions:
Higher social connectedness is associated with a greater likelihood of having optimal CVH. Individuals’ perceptions of the strength of their relationships could have cardioprotective benefits through promotion of favorable cardiovascular health behaviors and factors.
