Physical inactivity is a leading cause of premature death, disability and numerous chronic diseases. Minority and underserved populations in the United States and worldwide have a higher prevalence of physical inactivity affecting their morbidity and mortality rates. In the United States, African Americans are less physically active and have a higher proportion of many chronic diseases in comparison to Caucasians. This disparity needs to be well understood in order to design and implement effective interventions aimed at increasing physical activity levels among African Americans. In the present study, we conduct a systematic review (through 2010) of the qualitative literature pertaining to impediments and enablers to physical activity participation among African Americans. This review focuses on qualitative research due to its advantages in understanding attitudes and perceptions related to health behavior within the context of participants' natural environment. Findings are stratified by gender and age, to explore unique impediments and enablers based on age and sex and results are discussed within the socio-ecological model to account for the multi-level nature of factors affecting physical activity. Findings should be taken into account by researchers, program planners and policymakers when tailoring physical activity interventions to African American communities in the United States.

BackgroundQualitative research appears to be gaining acceptability in medical journals. Yet, little is actually known about the proportion of qualitative research and factors affecting its publication. This study describes the proportion of qualitative research over a 10 year period and correlates associated with its publication.DesignA quantitative longitudinal examination of the proportion of original qualitative research in 67 journals of general medicine during a 10 year period (1998–2007). The proportion of qualitative research was determined by dividing original qualitative studies published (numerator) by all original research articles published (denominator). We used a generalized estimating equations approach to assess the longitudinal association between the proportion of qualitative studies and independent variables (i.e. journals' country of publication and impact factor; editorial/methodological papers discussing qualitative research; and specific journal guidelines pertaining to qualitative research).FindingsA 2.9% absolute increase and 3.4-fold relative increase in qualitative research publications occurred over a 10 year period (1.2% in 1998 vs. 4.1% in 2007). The proportion of original qualitative research was independently and significantly associated with the publication of editorial/methodological papers in the journal (b = 3.688, P = 0.012); and with qualitative research specifically mentioned in guidelines for authors (b = 6.847, P<0.001). Additionally, a higher proportion of qualitative research was associated only with journals published in the UK in comparison to other countries, yet with borderline statistical significance (b = 1.776, P = 0.075). The journals' impact factor was not associated with the publication of qualitative research.ConclusionsDespite an increase in the proportion of qualitative research in medical journals over a 10 year period, the proportion remains low. Journals' policies pertaining to qualitative research, as expressed by the appearance of specific guidelines and editorials/methodological papers on the subject, are independently associated with the publication of original qualitative research; irrespective of the journals' impact factor.

IntroductionInsufficient physical activity is an established risk factor for numerous chronic diseases and for premature death. Accumulating evidence reveals that prolonged sedentary time is detrimental, independent of the protective effects of physical activity. Although studies have explored correlates of physical activity among ethnic minority populations, few have examined factors related to sedentary behavior. Therefore, we conducted a preliminary investigation into urban adults’ perceptions of sedentary behavior alongside perceived barriers and enablers to physical activity.MethodsIn-depth semi-structured interviews were used to evaluate perceptions of physical activity and sedentary behavior in a sample of low-income, ethnic minority adults. The framework approach guided researchers in analyzing the qualitative data.ResultsParticipants were well aware of the positive health benefits of physical activity. However, most admitted not regularly engaging in physical activity and cited numerous barriers to activity, such as lack of time, insufficient finances, and neighborhood crime. Enablers included weight loss, the presence of social support, and the availability of safe parks conducive to exercise. In comparison, participants were primarily unfamiliar with the term “sedentary behavior” and did not perceive a relationship between sedentary behavior and health outcomes.ConclusionOur findings illustrate the need to increase the awareness of negative health implications of prolonged sedentary time while continuing to address the multiple impediments to physical activity as a way to combat chronic disease.
