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 …

Involving Young People In The Care And Support Of People Living With Hiv/Aids In Zambia, Eka Esu-Williams, Katie D. Schenk, Joseph Motsepe, Scott Geibel, Anderson Zulu
HIV and AIDS
The Population Council, in collaboration with CARE International and Family Health Trust, conducted a study in Zambia to determine which care and support needs of people living with HIV and AIDS and their families could be met by trained youth, and to establish whether youth engaged in formalized care and support activities would increase their adoption of protective behaviors or reduce the stigma faced by members of AIDS-affected households. Discussions with caregivers and clients demonstrated that trained youth are able to meet a range of the needs of clients and orphans and vulnerable children, and that their efforts may be …

Adherence To Antiretroviral Therapy In Adults: A Guide For Trainers, Horizons Program, International Centre For Reproductive Health, Mombasa Coast Province General Hospital
HIV and AIDS
Over the last five years, there has been a rapid change in treatment strategies for HIV infection. With the advent of newer antiretrovirals, treatment has moved from mono-therapy and bi-therapy to triple drug therapy or Highly Active Antiretroviral Therapy. One of the foremost concerns of ARV programs is the ability of people living with HIV/AIDS to maintain near perfect adherence over the long term. To achieve the goal of antiretroviral therapy (ART), undetectable levels of the virus in the blood, patients are required to maintain more than 90–95% adherence. Adherence is defined as a patient’s ability to follow a treatment …

Vulnerability And Intervention Opportunities: Research Findings On Youth And Hiv/Aids In South Africa, Population Council
HIV and AIDS
The Nelson Mandela Children’s Fund (NMCF) seeks comprehensive local solutions to address the negative effects of HIV/AIDS on children, adolescents, households, and communities. To this end, NMCF initiated the Goelama Project, which uses a community mobilization strategy to catalyze action by local organizations and government bodies to prevent HIV infection and mitigate the socioeconomic impacts of the disease, particularly as they affect orphans and vulnerable children (OVC). This brief highlights key findings from an assessment of reproductive and sexual health knowledge and behaviors among nearly 5,000 youth from eight districts in three provinces in South Africa where the Goelama Project …
Public Posting As A Strategy To Increase Walking: A Worksite Intervention, Rayleen Earney, Timothy J. Bungum
Public Posting As A Strategy To Increase Walking: A Worksite Intervention, Rayleen Earney, Timothy J. Bungum
Environmental & Global Health Faculty Research
Because most American adults do not meet recommended physical activity guidelines, the need for new and innovative strategies is apparent. The current study employed public posting in an attempt to increase walking behavior in a worksite setting. Pedometer generated data was publicly posted in a prominent location in the worksite. In our study that utilized a pre-experimental design, we found that walking steps were statistically higher during the intervention and in a post intervention period as compared to the baseline data. We conclude that the public posting of physical activity data has the potential to increase walking behavior.
Perceptions Of Pediatric Overweight And Weight Management: A Comparison Of Parents And Physicians, Lisa K. Thomason
Perceptions Of Pediatric Overweight And Weight Management: A Comparison Of Parents And Physicians, Lisa K. Thomason
Masters Theses & Specialist Projects
Pediatric overweight is of paramount importance in Kentucky, as studies show prevalence rates are higher in the state than the national average. Research suggests that comprehensive treatments involving diet training, exercise training, and psychological counseling are most effective at reducing overweight in children. Little research has been done, however, to compare parents' and physicians' perceptions of obesity, its treatment, or barriers to weight management.
The purpose of this study is to examine differences in attitudes toward pediatric obesity and weight management among parents and physicians, specifically related to the importance of diet training, exercise training, and psychological counseling. Surveys were …

HIV and AIDS
Little is known about the use of voluntary counseling and testing (VCT) by youth, a group that comprises more than half of those newly infected with HIV. An exploratory study conducted in Nairobi, Kenya, and Kampala and Masaka in Uganda revealed that young people want information, confidentiality, low-cost HIV testing, and friendly, professional counseling. Two facilities in Kampala, the AIDS Information Center (AIC) and Naguru Teenage Information and Health Center (NTIHC), implemented new youth-oriented strategies to increase VCT utilization and satisfaction with services among young people. In 2001, AIC established a youth corner behind the regular adult clinic with a …

Integrating Adolescent Livelihood Activities Within A Reproductive Health Programme For Urban Slum Dwellers In India, Mary Philip Sebastian, Monica J. Grant, Barbara Mensch
Poverty, Gender, and Youth
This project, whose collaborators included CARE, the Centre for Operations Research and Training, and the Population Council, tested the impact of economic skills training among girls in a slum in Allahabad, India. Recognizing the relative disadvantage of adolescent girls, the study aimed to build an evidence base for adolescent livelihoods programs. Participating girls and their parents welcomed the program, and the baseline survey clearly indicated the appropriateness of an intervention that addresses the capabilities and opportunities available to adolescent girls—including both vocational training and savings schemes. However, few girls turned their new skills into economic gain, in part because of …

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 …

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.

The Effect Of A Livelihoods Intervention In An Urban Slum In India: Do Vocational Counseling And Training Alter The Attitudes And Behavior Of Adolescent Girls?, Barbara Mensch, Monica J. Grant, Mary Philip Sebastian, Paul C. Hewett, Dale Huntington
Poverty, Gender, and Youth
This Population Council working paper examines whether an experimental intervention for girls aged 14–19 that provided reproductive health information, vocational counseling and training, and assistance with opening savings accounts in slum areas of Allahabad in Uttar Pradesh, India had an effect on their attitudes and behaviors. Although the livelihoods program was acceptable to parents and feasible to implement, the project had only a minimal impact on the behavior and attitudes of adolescent girls in the experimental slums. The greatest changes between the baseline and the endline surveys were found in those outcomes that most closely reflected the content of the …

Back To The Future: The Future Of Long-Term Care In Massachusetts, Deborah H. Thomson, John J. Ford
Gerontology Institute Publications
The state of Massachusetts, like the rest of the United States, is facing an approaching crisis in long-term care. Over the next few decades the number of Massachusetts residents age 65 and older will soar. As these numbers increase, so will the need for long-term care.
Massachusetts is ill prepared to provide the services that will be needed. Our current system of health care benefits leaves many elders with gaps in coverage. Those individuals who need long-term services often impoverish themselves and their spouses before the state pays for their care. Others languish on waiting lists to receive services. Our …

Human Chorionic Gonadotropin Administration Is Associated With High Pregnancy Rates During Ovarian Stimulation And Timed Intercourse Or Intrauterine Insemination, Mohamed F. Mitwally, Sonya Abdel-Razeq, Robert F. Casper
Wayne State University Associated BioMed Central Scholarship
Abstract
Background
There are different factors that influence treatment outcome after ovarian stimulation and timed-intercourse or intrauterine insemination (IUI). After patient age, it has been suggested that timing of insemination in relation to ovulation is probably the most important variable affecting the success of treatment. The objective of this study is to study the value of human chorionic gonadotropin (hCG) administration and occurrence of luteinizing hormone (LH) surge in timing insemination on the treatment outcome after follicular monitoring with timed-intercourse or intrauterine insemination, with or without ovarian stimulation.
Methods
Retrospective analysis of 2000 consecutive completed treatment cycles (637 timed-intercourse and …

Ishraq: Safe Spaces To Learn, Play And Grow: Expansion Of Recreational Sports Program For Adolescent Rural Girls In Egypt, Nadia Zibani
Poverty, Gender, and Youth
Over the past three years, the Ishraq program in the villages of northern El-Minya, Egypt, grew from a novel idea into a vibrant reality. In the process, approximately 300 rural girls have participated in a life-transforming chance to learn, play, and grow into productive members of their local communities. Currently other villages—and soon other governorates—are joining the Ishraq network. Ishraq is a mixture of literacy, life-skills training, and—for girls who have been sheltered in domestic situations of poverty and isolation—a chance to play sports and games with other girls their age and develop a sense of self-worth and mastery; the …

Rapports de recherche scientifique
Le rotamètre est un instrument de mesure fréquemment employé pour déterminer le débit d’air fourni par les pompes à air ambiant qui servent à alimenter des systèmes de protection respiratoire à adduction d’air. À priori il s’agit d’un instrument relativement simple d’utilisation pouvant être inséré soit à l’extrémité d’un réseau d’alimentation d’air ou entre les composants du réseau. Si le rotamètre est inséré dans le réseau et qu’il est soumis à des conditions d’utilisation (pression et température de ligne) différentes des conditions de référence spécifiées par le manufacturier, le débit qu’il affichera devra être corrigé théoriquement, ce qui nécessite la …

Conception Des Cheminées À Minerai Et À Stérile, John Hadjigeorgiou, Jean-François Lessard
Rapports de recherche scientifique
La manutention du minerai et du stérile dans la plupart des mines souterraines repose sur un système de cheminées à minerai. Ces cheminées ont pour but de transférer, par gravité, le minerai depuis les niveaux supérieurs de la mine jusqu'au niveau de concassage et de hissage.
L’expérience a montré que les cheminées sont fréquemment aux prises avec des problèmes d’écoulement de même qu’avec des problèmes de stabilité. Les problèmes de stabilité sont causés, entre autre, par le régime de contraintes et, principalement, par les structures en place dans le massif rocheux. Les impacts et l'usure par abrasion au niveau des …
