Abstract 15099: Acculturation and Lifestyle Risk Behaviors in Korean Immigrants: Mediating Effects of Acculturative Stress and Body Image Discrepancy
Introduction: Due to genetic predisposition and acculturation experiences, Korean immigrants (KIs) are vulnerable to developing obesity and cardiovascular complications. However, few studies have examined indirect effects of acculturation on lifestyle risk behaviors and body mass index (BMI).
Hypothesis: We hypothesized that a latent variable of acculturation would have indirect effects on a latent variable of lifestyle risk behaviors (sedentary behavior, physical activity, dietary behavior, and sleep duration) and BMI through acculturative stress and body image discrepancy (BD=Current body image - ideal body image).
Methods: We conducted a cross-sectional study and recruited KIs aged 30 to 65 years via the internet or in person. Structural equation modeling was used with 367 KIs (mean age=41.82±10.82 years, 48.5% female, and 46.6% overweight or obesity).
Results: First, KIs’ lifestyle risk behaviors were characterized by only sedentary behavior and unhealthy dietary behavior (p<.05). Second, BD fully mediated acculturation– lifestyle risk behaviors relationship and partially mediated acculturation–physical activity and acculturation–sleep duration relationships; lower acculturation was related to more BD (p=.05) and more BD was related to greater risk of lifestyle behaviors, less physical activity, and shorter sleep duration (all p<.05). Acculturative stress partially mediated the relationship between acculturation and sleep duration; higher acculturation was related to lower acculturative stress (p<.05), which led to longer sleep duration (p<.05). Lastly, BMI was positively related to the latent variable of lifestyle risk behaviors (sedentary behavior and unhealthy dietary behavior) (p<.05).
Conclusions: Sedentary behavior and unhealthy dietary behavior primarily contributed to higher BMI in middle-aged KIs. Acculturative stress and BD play a crucial role in the relationship between acculturation and lifestyle behavior in KIs.
