OBJECTIVE -Markers of hemostasis and inflammation such as plasminogen activator inhibitor-1 (PAI-1) and fibrinogen have been associated with risk of type 2 diabetes. We aimed to identify food intake patterns influencing this pathway and evaluate their association with incident diabetes.
RESEARCH DESIGN AND METHODS -The Insulin Resistance AtherosclerosisStudy cohort included 880 middle-aged adults initially free of diabetes. At the 5-year follow-up, 144 individuals had developed diabetes. Usual dietary intake was ascertained with a 114-item food frequency questionnaire. Using reduced rank regression, we identified a food pattern maximizing the explained variation in PAI-1 and fibrinogen. Subsequently, the food patterndiabetes association was evaluated using logistic regression.RESULTS -High intake of the food groups red meat, low-fiber bread and cereal, dried beans, fried potatoes, tomato vegetables, eggs, cheese, and cottage cheese and low intake of wine characterized the pattern, which was positively associated with both biomarkers. With increasing pattern score, the odds of diabetes increased significantly (P trend Ͻ 0.01). After multivariate adjustment, the odds ratio comparing extreme quartiles was 4.3 (95% CI 1.7-10.8). Adjustment for insulin sensitivity and secretion and other metabolic factors had little impact (4.9, 1.8 -13.7).CONCLUSIONS -Our findings provide support for potential behavioral prevention strategies, as we identified a food intake pattern that was strongly related to PAI-1 and fibrinogen and independently predicted type 2 diabetes.
In 2006, the Centers for Disease Control and Prevention published guidelines for routine HIV screening in healthcare settings. Feasibility studies have demonstrated that screening is effective in high-volume, urban settings, but there are no data for smaller, more rural settings. The main objective of this study was to describe a routine HIV screening program at a community health center in South Carolina serving both urban and rural populations. Margaret J. Weston Community Health Center implemented routine HIV screening using rapid tests at its three locations on December 1, 2006. All individuals utilizing this center over the age of 13 years were screened for HIV unless they opted out. Nurses completed a survey about their experiences with the program. chi(2) tests and logistic regression models were used to analyze the data. In the first 8 months, among 985 eligible visits, 574 (58%) resulted in the patient being screened. The most common reason for refusal was "doesn't think s/he is at risk." Acceptance rates differed significantly by location (p = 0.01), from 62% in the urban site to 47% in the rural site. Other significant predictors of accepting HIV testing were race/ethnicity, age, and method of payment. Three hundred twenty-four (58%) individuals who were tested reported no history of being previously tested for HIV infection. Participation in the screening program was perceived favorably by nurses. This pilot project in a South Carolina community health center demonstrates that implementation of routine HIV screening is acceptable in small healthcare settings and in smaller cities and rural communities in the South.
Rural residence is a risk factor for late HIV diagnosis. This may lead to reduced treatment response to antiretroviral medications, increased morbidity and mortality, and greater HIV transmission risks among rural residents. New testing strategies are needed that address challenges to HIV testing and diagnosis specific to rural areas.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
