Introduction: Among Hispanic/Latina women, sedentary behavior is associated with adverse cardiometabolic biomarker profiles, but little is known about which variables contribute to sedentary time more. Hypothesis: We tested the hypothesis that demographic variables (e.g., education, employment status), psychosocial variables (e.g., depressive symptoms, caregiver burden), and neighborhood-environmental variables (e.g., walkability, neighborhood aesthetics) would be associated with sedentary time among women of Mexican heritage. Methods: The SOL CASITAS study assessed women of Mexican heritage residing in southern San Diego. Sedentary time was measured using an accelerometer for one week. Demographic, psychosocial, and perceived neighborhood-environment variables were assessed using surveys. 3 separate unweighted linear models were used to examine the relative contribution of each variable on the outcome variable of percent sedentary time out of total wear time. Model 1 included demographic variables only; model 2 included demographic and psychosocial variables; and model 3 included demographic, psychosocial, and neighborhood-environmental variables. Results: 358 participants were included with a mean age of 59±10.5 years. Participants averaged 11.2±1.5 hours of sedentary time per day. 17.3% of participants had obtained at least a high school diploma. Only 29.5% were employed full time. The majority (85.28%) were born outside the U.S. There were no significant associations (p < 0.05) between demographic, psychosocial, or neighborhood-environmental variables with percent sedentary time in any model. However, there were a few suggestive associations: 1) Greater than high school education was associated with 23% higher percent sedentary time compared to less than a high school education (p-value 0.08); 2) Higher caregiver burden was associated with 20% higher percent sedentary time (p-value 0.09); and 3) Higher participant-rated score of neighborhood aesthetics was associated with 7% lower percent sedentary time (p-value 0.12). Conclusions: Additional research is needed to understand correlates of sedentary time among women of Mexican heritage, and future studies should consider additional domains such as characteristics of the home environment.
