The association of C-reactive protein and physical activity among a church-based population of African Americans.

ABSTRACT: Regular physical activity can reduce systemic inflammation and, thereby, the burden of chronic inflammatory-related conditions. This study examined whether regular physical activity, measured subjectively (Rapid Assessment of Physical Activity [RAPA]) and objectively (Bodymedia's SenseWear® activity monitor [SWA]), is associated with inflammatory or glycemic control markers.Subjects were 345 participants of the Healthy Eating and Active Living in the Spirit (HEALS) lifestyle intervention among African American (AA) churches in South Carolina from 2009 to 2012. Linear regression analyses were performed to assess the relationship between both subjectively and objectively measured physical activity and inflammatory markers including high sensitivity C-reactive protein (CRP), interleukin-6 (IL-6), and glycosylated hemoglobin (HbA1c).Those who participated in regular physical activity (from RAPA) had lower CRP values compared to those who were sedentary (2.3 vs. 3.8mg/L, p<0.01). Lower levels of CRP or IL-6 were observed among those in the highest quartile of active energy expenditure (CRP: 2.0 vs. 3.6 mg/L, p=0.01) or moderate-vigorous physical activity minutes (CRP=1.7 vs. 4.5mg/L, p<0.01; IL-6=1.5 vs. 2.1pg/mL, p=0.01) compared to their lowest respective quartiles as measured by the SWA.Physical activity may improve chronic inflammation, which is a primary pathophysiological mechanism for numerous chronic disorders, especially among minority populations.

Project description:PURPOSE:To implement a multilevel, church-based intervention with diverse disparity populations using community-based participatory research and evaluate feasibility, acceptability, and preliminary effectiveness in improving obesity-related outcomes. DESIGN:Cluster randomized controlled trial (pilot). SETTING:Two midsized (?200 adults) African American baptist and 2 very large (?2000) Latino Catholic churches in South Los Angeles, California. PARTICIPANTS:Adult (18+ years) congregants (n = 268 enrolled at baseline, ranging from 45 to 99 per church). INTERVENTION:Various components were implemented over 5 months and included 2 sermons by pastor, educational handouts, church vegetable and fruit gardens, cooking and nutrition classes, daily mobile messaging, community mapping of food and physical activity environments, and identification of congregational policy changes to increase healthy meals. MEASURES:Outcomes included objectively measured body weight, body mass index (BMI), and systolic and diastolic blood pressure (BP), plus self-reported overall healthiness of diet and usual minutes spent in physical activity each week; control variables include sex, age, race-ethnicity, English proficiency, education, household income, and (for physical activity outcome) self-reported health status. ANALYSIS:Multivariate linear regression models estimated the average effect size of the intervention, controlling for pair fixed effects, a main effect of the intervention, and baseline values of the outcomes. RESULTS:Among those completing follow-up (68%), the intervention resulted in statistically significantly less weight gain and greater weight loss (-0.05 effect sizes; 95% confidence interval [CI] = -0.06 to -0.04), lower BMI (-0.08; 95% CI = -0.11 to -0.05), and healthier diet (-0.09; 95% CI = -0.17 to -0.00). There was no evidence of an intervention impact on BP or physical activity minutes per week. CONCLUSION:Implementing a multilevel intervention across diverse congregations resulted in small improvements in obesity outcomes. A longer time line is needed to fully implement and assess effects of community and congregation environmental strategies and to allow for potential larger impacts of the intervention.
