Dietary Carbohydrates And Breast Cancer Risk: A Prospective Study Of The Roles Of Overall Glycemic Index And Glycemic Load, Stephanie A. Navarro Silvera, Meera Jain, Geoffrey R. Howe, Anthony B. Miller, Thomas E. Rohan

Department of Public Health Scholarship and Creative Works

We examined breast cancer risk in association with overall glycemic index (GI), glycemic load (GL), and dietary carbohydrate and sugar intake in a prospective cohort of 49,613 Canadian women enrolled in the National Breast Screening Study who completed a self‐administered food frequency questionnaire between 1980 and 1985. Linkages to national mortality and cancer databases yielded data on deaths and cancer incidence, with follow‐up ending between 1998 and 2000. During a mean follow‐up of 16.6 years, we observed 1,461 incident breast cancer cases. GI, GL, total carbohydrate and total sugar intake were not associated with breast cancer risk in the total …

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 …

A Schematic For Focusing On Youth In Investigations Of Community Design And Physical Activity, Kevin J. Krizek, Amanda Birnbaum, David M. Levinson

Department of Public Health Scholarship and Creative Works

This paper provides a first step in addressing special considerations for youth in a relatively new area of physical activity research. After reviewing the urgent need for novel approaches to increasing physical activity, the growing interest in the effects of community design are discussed. Although most discussion on this topic has focused on adults, there are important differences between youth and adults that warrant a special focus on youth and need to be accounted for. This article presents a schematic that accounts for how and where youth spend their time, decomposing the day into time spent in travel and time …

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 …

It also provides formulae demonstrating the potential benefits to the standard error of the intervention effect of both adjustments for fixed and time-varying covariates, as well as correlations over time. These estimates will allow other researchers using these variables to plan their studies by …

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 …

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.

Reproductive Health

This operations research project evaluated the effect and impact of a basic education program, developed by TOSTAN, a nongovernmental organization based at Thiès, Senegal. The basic education program consisted of four modules: hygiene, problem-solving, women’s health, and human rights. Through these four themes, emphasis was placed on enabling the participants, who were mostly women, to analyze their own situation more effectively and thus find the best solutions for themselves. The GTZ Supra Regional Project for the Elimination of Female Genital Cutting funded implementation of the program in 90 villages in Kolda Region, and the Population Council’s Frontiers in Reproductive Health …

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 And Cost Of Implementing A Gender-Sensitive Reproductive Health Program In Bolivia, Erica Palenque, Lizzy Montano, Ricardo Vernon, Fernando Gonzales Salguero, Patricia Riveros, John H. Bratt

Reproductive Health

The Integral Health Coordination Program (Programa de Coordinación en Salud Integral or PROCOSI), a network of 24 Bolivian NGOs, and the Population Council’s Frontiers in Reproductive Health (FRONTIERS) program evaluated the effects of interventions on clinic clients and their partners, and estimated the costs of incorporating a gender perspective into service delivery. Results show that sexual and reproductive health service organizations can implement action plans to change organizational policies and service delivery practices and to improve their infrastructure and equipment to make them more convenient for clients. The results further show that the intervention made modest but important changes in …

Impact Of Improved Client-Provider Interaction On Women's Achievement Of Fertility Goals In Egypt, Laila Nawar, Ibrahim Kharboush, Magdi A. Ibrahim, Hesham Makhlouf, Susan E. Adamchak

Reproductive Health

A two-phase operations research study was launched in Egypt in early 2000 with the goal of demonstrating how improving the quality of client–provider interaction (CPI) could be achieved in large healthcare systems, specifically in relation to family planning. The study was designed to explore how CPI improvements could enhance family planning knowledge, method continuation rates, client satisfaction, and achievement of fertility goals. Client outcome variables were expected to improve as a result of improving client–provider interaction. The study recommends continued development and testing of innovative, attractive, and well-designed IEC messages that influence woman's fertility preferences; continuous training of health providers; …

The goal of this OR project was to test the efficacy of interventions to …

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 …

Community Approaches And Government Policy Reduce Hiv Risk In The Dominican Republic, Deanna Kerrigan, Luis Moreno, Bayardo Gomez, Hector Jerez, Ellen Weiss, Johannes Van Dam, Eva Roca, Clare Barrington, Michael D. Sweat

HIV and AIDS

Effective programs that avert new HIV infections among sex workers and their partners, and hence the general population, are critical components of national HIV-prevention strategies. Prevention efforts have frequently relied on interventions that reach members of these vulnerable groups as individuals, such as condom promotion and STI management. Now, many researchers and program implementers are increasingly turning to “environmental-structural” interventions that address the physical, social, and political contexts in which individual behavior takes place. A recent Horizons study conducted jointly with two Dominican NGOs—Centro de Orientación e Investigación Integral and Centro de Promoción e Solidaridad Humana—and the National Program for …

Equitable Access To Hiv Counseling And Testing For Youth In Developing Countries: A Review Of Current Practice, Ann P. Mccauley

HIV and AIDS

While many people get HIV-related counseling and testing, only those who receive pre- and post-test counseling, and test voluntarily, are participating in voluntary counseling and testing (VCT). The high rates of HIV infection among youth make it crucial to find programs to prevent infection. Because there is evidence that many adults benefit from VCT, there is increasing interest in extending these services to young people. VCT counseling helps adolescents evaluate their own behavior and its consequences. A negative test result offers the opportunity to recognize vulnerabilities and develop risk-reduction plans to adopt safe behaviors. Young people who test HIV-positive can …

Willingness To Pay Surveys For Setting Prices For Reproductive Health Products And Services: A User's Manual, Karen G. Fleischman Foreit, James R. Foreit

Reproductive Health

Social programs need to balance volume (coverage) and revenue (sustainability). The law of demand says that we cannot get both coverage and sustainability at the same time—as prices go up, demand will come down. Client loss with increasing prices is inevitable, except in those cases where starting prices are so low or demand is so high that demand is insensitive to price changes. Willingness to pay surveys allow program managers to simulate price-related changes in demand without actually changing prices, giving them a way to make pricing decisions based on empirical information. In making pricing decisions, managers of social programs …

Integration Of Reproductive Health Services For Men In Health And Family Welfare Centers In Bangladesh, Ubaidur Rob, Sharif M.I. Hossain, M.E. Khan, Ahmed Al-Sabir, Mohammed Ahsanul Alam

Reproductive Health

Since the mid-1970s, the Bangladesh national family planning program primarily focused on motivating women to use modern contraceptive methods and encouraging them to seek services from clinics. In addition, female field workers were recruited to deliver contraceptive methods at homes. The program design facilitated women’s access to information and medical care through clinics and home visits. In the process, however, the medical needs of males were marginalized. Men generally seek services from pharmacies, private practitioners, and district hospitals, and often ignore preventive steps and postpone seeking medical care for chronic health conditions. In cases of acute illness, they often resort …

Unwanted Pregnancy And Induced Abortion In Rajasthan, India: A Qualitative Exploration, Batya Elul, Hillary J. Bracken, Shalini Verma, Rajani Ved, Rajesh Singhi, Karin Lockwood

Reproductive Health

As part of a Population Council program of research on unwanted pregnancy and induced abortion in Rajasthan, the Council and Ibtada conducted a qualitative exploration of attitudes and behaviors regarding unwanted pregnancy and induced abortion in Alwar district. The study was intended to lay the groundwork for two quantitative studies on abortion undertaken subsequently in six districts of Rajasthan. The qualitative exploration shows that women, particularly those who are poor, turn to largely untrained community-level providers for abortion services. Additionally, women use home remedies in an often unsuccessful attempt to terminate unwanted pregnancies. Women with greater financial means obtain surgical …

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 …

Understanding Induced Abortion: Findings From A Programme Of Research In Rajasthan, India, Population Council

Reproductive Health

In India, abortion has been legal for over 30 years, following the enactment of the Medical Termination of Pregnancy (MTP) Act in 1971. While the MTP Act permits abortion for a broad range of social and medical reasons, it also includes provisions regarding delivery of services that have proved to constrain access to safe and legal abortion for the great majority of women in India. Due in part to these constraints, up to 90 percent of the six million induced abortions estimated to occur annually in India are illegal—provided in uncertified settings and/or by uncertified providers. Many are unsafe and …
