BACKGROUND: The HIV Infant Tracking System (HITSystem) is a web-based intervention linking providers of early infant diagnosis, laboratory technicians, and mothers and infants to improve outcomes for HIV-exposed infants. We aimed to evaluate the efficacy of the HITSystem on key outcomes of early infant diagnosis.

METHODS: We did a cluster-randomised trial at six hospitals in Kenya, which were matched on geographic region, resource level, and volume of patients (high, medium, and low). We randomly allocated hospitals within a matched pair to either the HITSystem (intervention; n=3) or standard of care (control; n=3). A random number generator was used to assign …

A Nationwide Study On The Prevalence Of Functional Gastrointestinal Disorders In School-Children., Miguel Saps, Jairo Enrique Moreno-Gomez, Carmen Rossy Ramírez-Hernández, John M. Rosen, C A. Velasco-Benitez

Manuscripts, Articles, Book Chapters and Other Papers

Introduction: Functional gastrointestinal disorders (FGIDs) are highly prevalent worldwide and are thought to result from the interplay of multiple factors that can vary from region to region. Nationwide studies can help understand the regional epidemiology and the pathogenesis of FGIDs. The objectives of this study were to determine the prevalence of FGIDs in school-children of Colombia and assess associated factors.

Methods: A cross-sectional study was carried out at twelve private and public schools in ten cities distributed through the four main geographic regions of Colombia. School-children completed a validated questionnaire to assess functional gastrointestinal disorders according to Rome III criteria. …

COMPLEMENTARY AND ALTERNATIVE MEDICINE (CAM) AND ADOLESCENT BODY MASS INDEX (BMI): A NATIONAL POPULATION-BASED STUDY

Abstract

Background

Childhood obesity rates in the United States have remained around 17% since the 1990s - this figure translates to an estimated 12.7 million obese children. Maintaining a healthy weight through adolescence may limit subsequent health risks in adulthood. Complementary and alternative medicine (CAM) encompasses a variety of non-pharmacological treatments and lifestyle choices that have been utilized in addition to or in place of typical Western medicine. The relationship between adolescent Body mass index (BMI) and the use of complementary and alternative medicine has …

This article reports on the outcomes of the Teens Eating for Energy and Nutrition at School (TEENS) study, a 2-year intervention study conducted in 16 middle schools with a goal of increasing students’ intakes of fruits, vegetables, and lower-fat foods. Despite positive interim results for students randomized to intervention schools, the positive effects of the intervention were not seen for the primary outcomes at the end of the 2nd year. Positive effects were seen only for a food choice score (suggesting that the students usually choose lower versus higher fat foods) and not for measures of food intake. Future studies …

Decreasing Barriers For Teens: Evaluation Of A New Teenage Pregnancy Prevention Strategy In School-Based Clinics, Abbey C. Sidebottom, Amanda Birnbaum, Sarah S. Nafstad

Sidebottom et al seek to evaluate the effects of the change in distribution systems on students' receipt of requested contraceptives and demand for contraceptive school-based clinics (SBC). The result of the study reveals that the average number of requests per student was higher under the voucher system, possibly as a consequence of expires vouchers resulting in repeated requests. The findings also suggest that SBCs could go a step further in reducing adolescents' barriers to accessing contraceptives by adopting an on-site direct delivery system..

Are Differences In Exposure To A Multicomponent School-Based Intervention Associated With Varying Dietary Outcomes In Adolescents?, Amanda S. Birnbaum, Leslie A. Lytle, Mary Story, Cheryl L. Perry, David M. Murray

Multicomponent interventions are recommended for health behavior change among adolescents. However, it is difficult to disentangle the effects of multiple intervention components. This article reports outcomes associated with varying levels of exposure to a school-based nutrition intervention, Teens Eating for Energy and Nutrition at School (TEENS). Four incremental exposureswere possible: (1) control group, (2) school environment interventions only, (3) classroom plus environment interventions, and (4) peer leaders plus classroom plus environment interventions. Patterns suggesting dose response were observed, with peer leaders reporting the largest increases in fruit, vegetable, and lower fat food consumption. Students exposed to classroom plus environment interventions …

Condom Availability In New York City Public High Schools: Relationships To Condom Use And Sexual Behavior., Sally Guttmacher, Lisa D. Lieberman, David Ward, Nick Freudenberg, Alice Radosh, Don Des Jarlais

Department of Public Health Scholarship and Creative Works

OBJECTIVES: This study examines the impact of the condom availability program in New York City public high schools by comparing rates of sexual activity and condom use for New York students and similar students in Chicago.

METHODS: A total of 7119 students from 12 randomly selected New York schools and 5738 students from 10 Chicago schools participated in a cross-sectional survey.

RESULTS: New York students, compared with Chicago students, reported equal rates of sexual activity but higher rates of condom use at last intercourse (odds ratio [OR] = 1.36). For higher-risk students (those with three or more sexual partners in …
