    Factors influencing abstinence, anticipation, and delay of sex among adolescent boys in high-STI prevalence communities
    (Elsevier, 2014-05) Cummings, Teresa; Auerswald, Colette L.; Ott, Mary A.; Department of Pediatrics, IU School of Medicine
    Purpose Abstinence is a core pregnancy and STI prevention strategy. We explore the attitudinal, behavioral, and family contexts relating to abstinence and the decision to delay sex among adolescent boys. Methods Adolescent boys ages 14–17 were recruited from community sites using a venue-based sampling method. All eligible boys at venues were invited to participate in an electronic survey. Question items included sexual behaviors, attitudes related to sex, relationships, masculine values, and family contextual items. Results We enrolled 667 participants, age 15.7 years, of diverse ethnicity. 252 (38%) were abstinent. Abstinent participants were younger, less likely to report non-coital behaviors, and reported lower conventional masculine values. Among abstinent participants, 62% planned to delay sex, while 38% anticipated sex in the next year. Participants with lower conventional masculine values, and more religious or moral motivations for abstinence were more likely to plan to delay sex. Discussion Abstinence among boys is common, even in high STI risk communities. For these boys, abstinence appears to be a complex behavioral decision, influenced by demographic, behavioral, attitudinal and contextual factors such as age, race, non-coital sexual behaviors and masculine values. Understanding the attitudes and contexts of abstinence, including plans to delay sex, can inform the development of public health programs for early fatherhood and STI prevention.

    Lifestyle and metformin interventions have a durable effect to lower CRP and tPA levels in the diabetes prevention program except in those who develop diabetes
    (American Diabetes Association, 2014-08) Goldberg, Ronald B.; Temprosa, Marinella G.; Mather, Kieren J.; Orchard, Trevor J.; Kitabchi, Abbas E.; Watson, Karol E.; Diabetes Prevention Program Research Group; Department of Medicine, IU School of Medicine
    OBJECTIVE: We evaluate whether lifestyle and metformin interventions used to prevent diabetes have durable effects on markers of inflammation and coagulation and whether the effects are influenced by the development of diabetes. RESEARCH DESIGN AND METHODS: The Diabetes Prevention Program was a controlled clinical trial of 3,234 subjects at high risk for diabetes who were randomized to lifestyle, metformin, or placebo interventions for 3.4 years. Diabetes was diagnosed semiannually by fasting glucose and annually by oral glucose tolerance testing. In addition to baseline testing, anthropometry was performed every 6 months; fasting insulin yearly; and hs-CRP, tissue plasminogen activator (tPA), and fibrinogen at 1 year and end of study (EOS). RESULTS: CRP and tPA levels were unchanged in the placebo group but fell in the lifestyle and metformin groups at 1 year and remained lower at EOS. These reductions were not seen in those who developed diabetes over the course of the study despite intervention. Fibrinogen was lower at 1 year in the lifestyle group. Differences in weight and weight change explained most of the influence of diabetes on the CRP response in the lifestyle group, but only partly in the placebo and metformin groups. Weight, insulin sensitivity, and hyperglycemia differences each accounted for the influence of diabetes on the tPA response. CONCLUSIONS: Lifestyle and metformin interventions have durable effects to lower hs-CRP and tPA. Incident diabetes prevented these improvements, and this was accounted for by differences in weight, insulin resistance, and glucose levels.
