Isotemporal Analysis of the Association of Objectively Measured Physical Activity With Depressive Symptoms: Results From Hispanic Community Health Study/Study of Latinos (HCHS/SOL).

ABSTRACT: BACKGROUND:The burden of depression among Hispanics/Latinos indicates the need to identify factors related to depressive symptoms. This paper examines the relationship of physical activity (PA) and sedentary behavior (SB) with depressive symptoms in Hispanic/Latinos. METHODS:The Hispanic Community Health Study / Study of Latinos (HCHS/SOL) is a population-based, cohort study of Hispanic/Latinos in 4 United States metropolitan areas. Objectively measured PA was coded into: sedentary behavior (SB), light-intensity (LPA), moderate-intensity (MPA), and vigorous-intensity (VPA); and the Center for Epidemiological Studies Depression Scale-10 assessed depressive symptoms. Multiple regression analysis utilizing isotemporal substitution, adjusted for relevant covariates, examined PA as predictors of depressive symptoms. RESULTS:Substitution of 1 hour of SB with VPA resulted in a significant decrease in depressive symptoms (? = -1.215, P = .021). Similar decreases were observed when VPA replaced LPA (? = -1.212, P = .021) and MPA (? = -1.50 P = .034). MPA and LPA were not associated with lower depressive symptoms. CONCLUSIONS:Previous research has focused on the relationship of MVPA on depressive symptoms. Our results suggest these constructs should be examined separately as they may have unique relationships with depressive symptoms. The association of SB with greater depressive symptoms confirms previous reports.

Project description:BackgroundSedentary behavior is recognized as a distinct construct from lack of moderate-vigorous physical activity and is associated with deleterious health outcomes. Previous studies have primarily relied on self-reported data, whereas data on the relationship between objectively measured sedentary time and cardiometabolic biomarkers are sparse, especially among US Hispanics/Latinos.Methods and resultsWe examined associations of objectively measured sedentary time (via Actical accelerometers for 7 days) and multiple cardiometabolic biomarkers among 12 083 participants, aged 18 to 74 years, from the Hispanic Community Health Study/Study of Latinos (HCHS/SOL). Hispanics/Latinos of diverse backgrounds (Central American, Cuban, Dominican, Mexican, Puerto Rican, and South American) were recruited from 4 US cities between 2008 and 2011. Sedentary time (<100 counts/min) was standardized to 16 hours/d of wear time. The mean sedentary time was 11.9 hours/d (74% of accelerometer wear time). After adjustment for moderate-vigorous physical activity and confounding variables, prolonged sedentary time was associated with decreased high-density lipoprotein cholesterol (P=0.04), and increased triglycerides, 2-hour glucose, fasting insulin, and homeostatic model assessment of insulin resistance (all P<0.0001). These associations were generally consistent across age, sex, Hispanic/Latino backgrounds, and physical activity levels. Even among individuals meeting physical activity guidelines, sedentary time was detrimentally associated with several cardiometabolic biomarkers (diastolic blood pressure, high-density lipoprotein cholesterol, fasting and 2-hour glucose, fasting insulin and homeostatic model assessment of insulin resistance; all P<0.05).ConclusionsOur large population-based, objectively derived data showed deleterious associations between sedentary time and cardiometabolic biomarkers, independent of physical activity, in US Hispanics/Latinos. Our findings emphasize the importance of reducing sedentary behavior for the prevention of cardiometabolic diseases, even in those who meet physical activity recommendations.

Project description:BackgroundCardiovascular disease (CVD) risk factor control is a cornerstone of diabetes mellitus management. Little is known about relationships of objectively measured sedentary time and physical activity with major CVD risk factor control in individuals with diabetes mellitus. We examined associations of objectively measured sedentary time and moderate-to-vigorous physical activity with reaching major CVD risk factor control goals among US Hispanic/Latino adults with diabetes mellitus.Methods and resultsThis cross-sectional analysis included 1699 participants with diabetes mellitus from the Hispanic Community Health Study/Study of Latinos (2008-2011). Logistic regression models were used to estimate the odds ratios (ORs) of meeting the following 5 major CVD risk factor control goals: hemoglobin A1c <7.0%; systolic/diastolic blood pressure <140/80 mm Hg; triglycerides <150 mg/dL; low-density lipoprotein cholesterol <100 mg/dL; and high-density lipoprotein cholesterol >40/50 mg/dL for men/women. After adjustment for covariates including moderate-to-vigorous physical activity, less sedentary time was associated with increased odds of reaching hemoglobin A1c (OR=1.76 [95% CI: 1.10, 2.82]) and triglyceride control goals (OR=2.16 [1.36, 3.46]), and reaching ≥3 CVD risk factor control goals (OR=2.08 [1.34, 3.23]) (all ORs for comparisons of extreme tertiles of sedentary time). Moderate-to-vigorous physical activity was not associated with reaching any CVD risk factor control goals. Substituting 60-min/day of sedentary time with light-intensity physical activity was associated with increased odds of reaching hemoglobin A1c (OR=1.18 [1.04, 1.35]), high-density lipoprotein cholesterol (OR=1.17 [1.04, 1.32]), and triglyceride (OR=1.20 [1.05, 1.36]) control goals.ConclusionsAmong US Hispanic/Latino adults with diabetes mellitus, less sedentary time, but not moderate-to-vigorous physical activity, was associated with improved CVD risk factor control, specifically in reaching hemoglobin A1c and triglyceride control goals.
