Objectives: We assessed the agreement between self-reported and accelerometer-assessed physical activity (PA) in African-American adults by sex, education, income, and weight status. Methods: Participants (N = 274) completed the International PA Questionnaire short form (IPAQS), Behavioral Risk Factor Surveillance System (BRFSS) PA questions, and PA Questionnaire (PAQ) and a 7-day accelerometer protocol using a waist-worn ActiGraph GT3X accelerometer. Inter-relationships among PA measures were assessed by sociodemographics. Results: Participants consistently reported doing ≥150 minutes of moderate-to-vigorous-intensity PA (MVPA) per week via self-report measures and did 113.5±179.4 minutes of accelerometer-assessed MVPA/week. Men self-reported and did more MVPA than women (p < .01). Regardless of sex, there were low correlations between self-report and accelerometer-assessed MVPA (r = .092-.190). Poor agreement existed between self-report and accelerometry for classifying participants as meeting PA recommendations (Cohen κ = .054-.136); only half of the participants were classified the same by both self-report and accelerometry. Conclusions: There was generally poor relative agreement between self-report and accelerometer-based assessments of MVPA in this sample of African-American adults. Findings suggest that self-report measures may perform better among African-American women than men, regardless of socioeconomic or weight status. [ABSTRACT FROM AUTHOR]

Objectives. The purpose of this study was to address current gaps in the literature by examining the associations of fast food restaurant (FFR) density around the home and FFR proximity to the home, respectively, with body mass index (BMI) among a large sample of African American adults from Houston, Texas. Methods. We used generalized linear models with generalized estimating equations to examine associations of FFR density at 0.5-, 1-, 2-, and 5-mile road network buffers around the home with BMI and associations of the closest FFR to the home with BMI. All models were adjusted for a range of individual-level covariates and neighborhood socioeconomic status. We additionally investigated the moderating effects of household income on these relations. Data were collected from December 2008 to July 2009. Results. FFR density was not associated with BMI in the main analyses. However, FFR density at 0.5, 1, and 2 miles was positively associated with BMI among participants with lower incomes (P £ .025). Closer FFR proximity was associated with higher BMI among all participants (P < .001), with stronger associations emerging among those of lower income (P < .013) relative to higher income (P < .014). Conclusions. Additional research with more diverse African American samples is needed, but results supported the potential for the fast food environment to affect BMI among African Americans, particularly among those of lower economic means.

Objectives: To examine associations of the US and community subjective social status (SSS) ladders with smoking sta­tus, at-risk drinking, fruit and vegetable intake, physical activity, and body mass index among 1467 church-going African American adults from a larger cohort study. Methods: Regression analyses, adjusted for sociodemographics, exam­ined associations between SSS ladders and health behaviors. Results: The SSS-US ladder was significantly associated with fruit and vegetable consumption (p = .007) and physical activity (p = .005). The SSS-community ladder was not sig­nificantly associated with any health be­haviors. Conclusions: Among this sam­ple of African Americans, the SSS-US ladder is more predictive of some health behaviors than is the SSS-community ladder. [ABSTRACT FROM AUTHOR]
