Changes in social support over time in a faith-based physical activity intervention.

African-American women report higher levels of chronic conditions and church attendance relative to the overall US population. Therefore, efforts have increased over the past decade to design church-based health promotion programs. The present study compared changes in religiosity, religious social support and general social support across time within a church-based physical activity study. In a clustered randomized controlled trial, 31 churches and ∼15 African-American women per church were recruited to participate. Churches were randomized to one of three 10-month programs to promote physical activity: faith-integrated (FI), non-faith integrated (NFI) or self-guided control program (C). Comparisons were made between baseline and 10-month time points to assess differences over time. A significant reduction in general social support was observed across all groups. Private religious practices and religious emotional support received increases in C and FI, respectively. Prior research findings and the current study highlight difficulty in demonstrating strong, unilateral changes in religiosity, social support and health. Additional research is needed to identify more accurate measures of these concepts. Findings from the current study have implications for the role of social support in future church-based health promotion studies.

Genotype-specific prevalence and distribution of human papillomavirus genotypes in underserved Latino women with abnormal Papanicolaou tests.

INTRODUCTION: Knowledge about the prevalence and distribution of human papillomavirus (HPV) genotypes in cervical premalignant and malignant lesions is crucial to guide development of clinical management strategies and prophylactic vaccines. The aim of this study was to determine HPV genotype-specific prevalence and distribution in an underserved cohort of Latino women. MATERIALS AND METHODS: From December 2009 to April 2011, 808 SurePath cervicovaginal specimens were collected from women who were referred from charity clinics for abnormal Papanicolaou tests. The patients' average age was 36.5 years (range 19-85 years). The specimens were tested for HPV genotypes by DNA microarray and sequencing assays. RESULTS: The HPV infection rate was extremely high (93% for any HPV and 64% for high-risk [HR]-HPV), with frequent multiple-strain infection (39%). Younger age (<30 years) was associated with frequent HR-HPV infection, multiple strain infections, and cytologic abnormalities. When compared with previous reports, HPV 16 remained the most common genotype (44.6%) in women with high-grade squamous intraepithelial lesion; however, a significant increase in HPV 31 (17.9%) and 45 (10.7%) and a decrease in HPV 35, 52, 33, and 66 were observed. CONCLUSIONS: The HPV genotype-specific prevalence and distribution pattern in this cohort of underserved Latino women differed significantly from previously published data in the United States. Understanding the potentially changing trends in HPV distribution pattern will help guide the development of appropriate preventive and therapeutic strategies for both underserved and general populations.
