A Theater-Based Approach To Primary Prevention Of Sexual Behavior For Early Adolescents, Jessica B. Janega, David M. Murray, Sherri P. Varnell, Jonathan L. Blitstein, Amanda Birnbaum, Leslie A. Lytle

Department of Public Health Scholarship and Creative Works

This article compares four mixed-model analyses valid for group-randomized trials (GRTs) involving a nested cohort design with a single pretest and posttest. This study makes estimates of intraclass correlations (ICCs) available to investigators planning GRTs addressing dietary outcomes. It also provides formulae demonstrating the potential benefits to the standard error of the intervention effect (σΔ) from adjustments for both fixed and time-varying covariates and correlations over time. These estimates will allow other researchers using these variables to plan their studies by estimating a priori detectable differences and sample size requirements for any of the four analytic options. These methods are …

School-Based Approaches To Affect Adolescents’ Diets: Results From The Teens Study, Leslie A. Lytle, David M. Murray, Cheryl L. Perry, Mary Story, Amanda Birnbaum, Martha Y. Kubik, Sherri Varnell

Department of Public Health Scholarship and Creative Works

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 …

An Assessment Of Hiv/Aids Risk In Higher Education Students In Yerevan, Armenia, Talin Babikian, Mary Catherin Freier, Gary L. Hopkins, Ralph Diclemente, Duane C. Mcbride, Matt Riggs

Faculty Publications

Armenia's current sociopolitical and economic instability and the alarming HIV incidence rates in neighboring countries amplify its risk for a national epidemic. The goals of this study were to assess HIV/AIDS knowledge and risk behaviors among higher education students in Yerevan. Knowledge of HIV transmission through sexual intercourse was markedly higher than that on intravenous transmission and prevailing myths; however, HIV/AIDS knowledge was not related to risk behaviors. Tobacco and alcohol prevalence was relatively high. Students reported risky sexual behaviors, including inconsistent condom use, casual sex, and multiple partners. In addition to descriptive statistics delineating gender differences across the target …

Encuestas De Voluntad De Pago Para Fijar Precios De Productos Y Servicios De Salud Reproductiva: Manual De Usuarios, Karen G. Fleischman Foreit, James R. Foreit

Reproductive Health

Social programs need to balance volume (coverage) and income (sustainability). The law of supply and demand states that we can not obtain coverage and support at the same time, because when prices rise, demand decreases. This manual presents willingness-to-pay (WTP) surveys that allow program managers to simulate changes in demand related to price, without actually changing prices. The Population Council with The Futures Group International developed these surveys that can be used for existing and new products and services, collect responses from clients with no formal education with sensitivity to their individual characteristics, and provide conservative estimates that accurately predict …

Medicalization Of Female Genital Cutting Among The Abagusii In Nyanza Province, Kenya, Carolyne Njue, Ian Askew

Reproductive Health

This study sought to understand the role that health providers play in the medicalization of female genital cutting (FGC) among the Abagusii community in western Kenya, among whom the practice continues to be almost universal. Interviews with service providers and their clients revealed an overwhelming belief that FGC fulfills a traditional cultural obligation among the Abagusii, and that it limits a woman’s sexual desire and confers respect on girls. New approaches are needed within this community to present FGC as violating human rights and national laws, as well as threatening girls’ and women’s health. The study recommends measures such as …

Effects Of Igss' Job Aids-Assisted Balanced Counseling Algorithms On Quality Of Care And Client Outcomes, Federico R. Leon, Carlos Brambila, Marisela De La Cruz, John H. Bratt, Gustavo Gutierrez, Veronica Davila, Carlo Boniato, Alex Rios

Reproductive Health

This study identified a need to improve the quality of care at the main maternity hospital of the Social Security Institute (IGSS) in Guatemala. Problems included very short counseling sessions, counseling not focused on clients’ needs, redundancy in the role of physicians and social workers as providers, skewed method mix, and low client return rate for method resupply. The intervention, using Balanced Counseling Algorithms, changed the counseling behavior of physicians and social workers and enhanced the quality of family planning care. The report includes recommendations for continuing these improvements: monitoring provider implementation of the job aids–assisted Balanced Counseling Algorithms, monitoring …

Strengthening Sti Treatment And Hiv/Aids Prevention Services In Carletonville, South Africa, Lewis Ndhlovu, Catherine Searle, Johannes Van Dam

HIV and AIDS

Although knowledge about HIV/AIDS is widespread in South Africa, adult HIV prevalence is high, indicating high levels of risky sexual behavior. Understanding the gap between knowledge and behavior requires an examination of the social context in which the epidemic occurs. The Horizons Program conducted an intervention study in the Carletonville area to study the social determinants of the HIV epidemic and to assess the impact of a targeted program of HIV and STI prevention and service delivery. In 1998, the Mothusimpilo (“Working together for health”) Intervention Project (MIP) was launched to reduce community prevalence of HIV and other STIs and …

Experience From A Community-Based Education Program In Burkina Faso: The Tostan Program, Djingri Ouoba, Zakari Congo, Nafissatou J. Diop, Molly Melching, Baya Banza, Georges Guiella, Inge Baumgarten

Reproductive Health

This study describes a project that tested the feasibility and effectiveness of replicating the village empowerment program (VEP) developed by the Senegalese NGO, TOSTAN, in Burkina Faso. Although originally developed for empowering women, the program implemented in Burkina Faso also involved men because of their key role in such decisions. Frontiers in Reproductive Health, with funding from USAID and the GTZ Supra Regional Project for the Elimination of FGC, supported the adaptation, implementation, and evaluation of the VEP model in 23 villages in the province of Bazega/Zoundwéogo. In the existing social climate among the Burkinabé, where there is widespread awareness …

Socioeconomic Disadvantage And Unsafe Sexual Behaviors Among Young Women And Men In South Africa, Kelly Hallman

Poverty, Gender, and Youth

This study investigates how relative socioeconomic status influences the sexual behaviors of young women and men aged 14–24 years in KwaZulu-Natal Province, South Africa—an environment characterized by high HIV prevalence and high rates of poverty and inequality. Relative economic disadvantage is found to significantly increase the likelihood of a variety of unsafe sexual behaviors and experiences. Poorer young people, especially females, also have significantly lower access to media sources for family planning information. Without sufficient attention in the design and placement of HIV prevention programs to the economic and social conditions in which individuals live, the potential effectiveness of the …

Bridging The Gap Between Evidence-Based Innovation And National Health-Sector Reform In Ghana, John Koku Awoonor-Williams, Ellie S. Feinglass, Rachel Tobey, Maya Vaughan-Smith, Frank K. Nyonator, Tanya C. Jones, James F. Phillips

Poverty, Gender, and Youth

Although experimental trials often identify optimal strategies for improving community health, transferring operational innovation from well-funded research programs to resource-constrained settings often languishes. Because research initiatives are based in institutions equipped with unique resources and staff capabilities, results are often dismissed by decisionmakers as irrelevant to large-scale operations and national health policy. This article describes an initiative undertaken in Nkwanta District, Ghana, focusing on this problem. The Nkwanta District initiative is a critical link between the experimental study conducted in Navrongo, Ghana, and a national effort to scale up the innovations developed in that study. A 2002 Nkwanta district-level survey …

Guérir Les Blessures, Faire Naître L’Espoir: Le Partenariat Tanzanien Contre La Fistule Obstétricale, Thoraya Ahmed Obaid, Erica Chong

Poverty, Gender, and Youth

This edition of Quality/Calidad/Qualité describes a partnership formed to combat obstetric fistula in Tanzania. The Bugando Medical Center, the Women’s Dignity Project, the Tanzania Midwives Association, and the government cooperated on an extensive program for surgical repair, prevention, and policy research and activities. Lessons learned: 1) Fistula programs need to address social as well as medical issues. 2) Most repairs are successful, making an enormous difference in women’s lives. 3) Relatively little funding is necessary to start up a fistula program. 4) Fistula programs are vehicles for broader conversations about gender and poverty.

Testing The Effectiveness Of Integrating Community-Based Approaches For Encouraging Abandonment Of Female Genital Cutting Into Care's Reproductive Health Programs In Ethiopia And Kenya, Jane Chege, Ian Askew, Susan Igras, Jacinta Muteshi-Strachan

Reproductive Health

CARE International, with technical support from the Frontiers in Reproductive Health Program completed a study in Ethiopia and Kenya designed to test the effectiveness of education activities using behavior change communication (BCC) approaches and advocacy activities by religious and other key leaders to abandon female genital cutting (FGC). In Ethiopia, the increased knowledge of harmful FGC effects and human rights issues translated to a positive attitude in support of FGC abandonment and an intention not to cut their daughters in the future. In Kenya, the analysis indicated mixed results in attitude and intended behavior change.

Making Motherhood Safer In Egypt, Karima Khalil, Farzaneh Roudi-Fahimi

Reproductive Health

Fewer Egyptian women die of maternal causes today than they did 10 or 15 years ago, due in large part to the national safe motherhood program. Nevertheless, maternal mortality is still relatively high, and the country faces challenges in reducing it further. Many of these challenges involve addressing the delays women face when they need essential obstetric care. In Egypt and other countries, most maternal deaths could be avoided if women had timely access to high-quality emergency obstetric services. Although Egypt’s level of maternal mortality is relatively high by international standards, recent evidence suggests that a woman’s lifetime risk of …

Forced Sexual Relations Among Married Young Women In Developing Countries, Deepika Ganju, William Finger, Shireen J. Jejeebhoy, Vijaya Nidadavolu, K.G. Santhya, Iqbal Shah, Shyam Thapa, Ina Warriner

Poverty, Gender, and Youth

Recent research in developing countries suggests that a considerable number of young women may experience forced sex within marriage, but most women may be inhibited from reporting these experiences due to shame, fear of reprisal, or deep-rooted unequal gender norms. In September 2003, a global consultative meeting on nonconsensual sex among young people in developing countries was held in New Delhi, India. The meeting was organized by the Population Council in collaboration with World Health Organization/Department of Reproductive Health and Research, and Family Health International/YouthNet. Participants included researchers, legal analysts, representatives from community-based NGOs, policy-makers, and young people themselves. Papers …

The Experience Of Adolescence In Rural Amhara Region, Ethiopia, Annabel Erulkar, Tekle-Ab Mekbib, Negussie Simie, Tsehai Gulema

Poverty, Gender, and Youth

This study aims to broaden the understanding of young lives in rural Ethiopia, specifically, Amhara Region. It finds that over half of the adolescents in the sample had never been to school. The most common reason for boys and girls not attending school was poverty, followed by early marriage for girls, and too many work responsibilities for boys. It finds that over half of the adolescents interviewed were illiterate. The study offers suggestions to address the programmatic needs of rural youth as well as neglected subgroups of adolescents.
