Access to antiretroviral therapy for adults and children with HIV infection in developing countries: Horizons studies, 2002-2008.
(17/30)
The Access-to-Treatment research initiative of the Population Council's Horizons program undertook 11 projects across Asia and sub-Saharan Africa from 2002 to 2008. The projects included a variety of cross-sectional exploratory studies, situation analyses, and longitudinal randomized, controlled intervention studies that examined service delivery, community awareness, health-seeking behaviors, adherence, cost, and other factors affecting treatment for adults and children infected with human immunodeficiency virus (HIV). This article summarizes the key findings and lessons learned from these projects, and examines cross-cutting issues such as stigma, quality of life, and sexual-risk behaviors among people living with HIV and acquired immunodeficiency syndrome on antiretroviral therapy. The article concludes with recommendations for evidence-based programming and future research around treatment for both children and adults. (+info)
HIV vulnerability of men who have sex with men in developing countries: Horizons studies, 2001-2008.
(18/30)
While male-to-male sexual behavior has been recognized as a primary risk factor for human immunodeficiency virus (HIV), research targeting men who have sex with men (MSM) in less-developed countries has been limited due to high levels of stigma and discrimination. In response, the Population Council's Horizons Program began implementing research activities in Africa and South America beginning in 2001, with the objectives of gathering information on MSM sexual risk behaviors, evaluating HIV-prevention programs, and informing HIV policy makers. The results of this nearly decade-long program are presented in this article as a summary of the Horizons MSM studies in Africa (Senegal and Kenya) and Latin America (Brazil and Paraguay), and include research methodologies, study findings, and interventions evaluated. We also discuss future directions and approaches for HIV research among MSM in developing countries. (+info)
Improving the lives of vulnerable children: implications of Horizons research among orphans and other children affected by AIDS.
(19/30)
From 1997 through 2007, the Horizons program conducted research to inform the care and support of children who had been orphaned and rendered vulnerable by acquired immunodeficiency syndrome in sub-Saharan Africa. Horizons conducted studies in Kenya, Malawi, Rwanda, South Africa, Uganda, Zambia, and Zimbabwe. Research included both diagnostic studies exploring the circumstances of families and communities affected by human immunodeficiency virus (HIV) and evaluations of pioneering intervention strategies. Interventions found to be supportive of families included succession planning for families with an HIV-positive parent, training and supporting youth as caregivers, and youth mentorship for child-headed households. Horizons researchers developed tools to assess the psychosocial well-being of children affected by HIV and outlined key ethical guidelines for conducting research among children. The design, implementation, and evaluation of community-based interventions for orphans and vulnerable children continue to be a key gap in the evidence base. (+info)
Park rangers as public health educators: the Public Health in the Parks Grants Initiative.
(20/30)
Federal health services grants amounted to about $1.8 billion in fiscal year 1985. The total amount was about $100 million less, about 6 percent, than in 1980. Reductions in the health planning program accounted for most of the decline in absolute dollars. The four formula grants to State agencies amounted to about $1.0 billion in 1985, about 60 percent of the total. The largest formula grants were for maternal and child health services and for alcohol, drug abuse, and mental health services. Project grants to selected State and local agencies amounted to about $.8 billion. There was 12 such grants in 1985 (compared with 34 in 1980). The largest, for community health services, equaled almost half the total. In real, inflation-adjusted dollars, the decline in Federal funds for these programs exceeded a third during the 5-year period. The overall dollar total in real terms in 1985 approximated the 1970 level. The ratio of formula grants to project grants in 1985 was similar to that in 1965. Studies of the impact of changes in Federal grants have found that while the development of health programs has been seriously constrained in most cases, their nature has not been substantially altered. In some cases broader program approaches and allocations have been favored. Established modes of operations and administration have generally been strengthened. Some efficiencies but few savings in administration have been identified. Replacement of reduced Federal funding by the States has been modest but has increased over time, especially for direct service activities. These changes reflect the important influence of professionalism in the health fields and the varying strengths of political interest and influence among program supporters. The long-term impact on program innovation is not yet clear. (+info)
An evaluation of subsidized rural primary care programs: II. The environmental contexts.
(24/30)
The placement of subsidized primary care programs in rural communities has been an important aspect of national health policy over the last decade. Using survey and secondary data from programs in over 700 counties in the United States, it was found that while about one-fourth of all counties with some rural populations have been affected by these programs, certain environmental factors are associated with more or less likelihood of placement. High levels of need and low levels of health care resources are positively associated with the presence of a program. States with health policy climates supportive of reimbursement and broader staffing of primary care programs also contained programs in a higher proportion of their rural counties. The effects of decreased federal funding, increased state responsibility, and the precarious market conditions for primary care programs are discussed with emphasis on the mechanisms for developing favorable climates for these programs.
