简要总结
The purpose of this study is to evaluate a multilevel economic and food security program (Support to Able-Bodied Vulnerable groups to Achieve Food Security; SAFE) in rural central Malawi as implemented and assigned by CARE-Malawi on HIV vulnerability and other health outcomes.
Hypothesis: HIV vulnerability can be reduced through a coordinated set of locally tailored individual and structural interventions that reduces poverty, reduces food insecurity, strengthens community bonds, and addresses gender inequality.
详细描述
Purpose:
Poverty and lack of a predictable, stable source of food are two fundamental determinants of ill health, including HIV/AIDS. Conversely, episodes of poor health and death from HIV can disrupt the ability to maintain economic stability in affected households, especially those that rely on subsistence farming. However, little empirical research has examined if, and how, improvements in people's economic status and food security translate into changes in HIV vulnerability.
The purpose of the SAGE4Health study is therefore to evaluate a large-scale economic development program implemented by CARE-Malawi to examine mechanisms and magnitude of impact on economic livelihoods, food security, and health. Specifically, the study aims to examine how socioeconomic changes may affect vulnerability to HIV and other risks that can overwhelm rural households in subsistence environments.
To contextualize the study location, it is important to note that HIV/AIDS, poverty and food insecurity contribute substantially to morbidity and mortality in sub-Saharan Africa. The Republic of Malawi, in southeastern Africa, bears one of the heaviest HIV disease burdens globally. Poverty is endemic in Malawi; more than half of its estimated 15 million people live on less than a dollar a day. Food insecurity, defined as having uncertain or limited access to nutritionally adequate food, or being unable to procure food in socially acceptable ways, is an aggravated problem in Malawi.
To better understand the context of HIV in Malawi, and to determine potential responses, it is important to consider HIV within an ecosocial framework. Moving beyond the conventional focus on proximal factors contributing to HIV vulnerability, like individual risk behaviors, it is essential that interventions address poverty and food insecurity as interrelated distal factors in the HIV pandemic, especially in countries like Malawi. Poverty has been consistently recognized as a risk factor for food insecurity and HIV, and food insecurity a risk factor for poor HIV-related outcomes.

主要结局
Change in economic status
时间窗: Change in economic status between baseline (early stages of intervention), 18-month follow-up (end of intervention), and 36 month follow-up (post-intervention)
Change in economic status between baseline (early stages of intervention), 18-month follow-up (end of intervention), and 36 month follow-up (post-intervention), as measured by a questionnaire containing questions on sources of livelihood (formal employment/wage labor, ganyu/casual labor, crop farming, livestock farming, trading/selling, etc.); exposure and coping methods to economic crises like major illness, environmental disasters, death of household member, etc.; housing quality like roof type (thatched roof, corrugated metal roof, tile, other), floor type (earth/mud, cement, tile, other), wall type (mud, brick, etc.); household assets like ownership of a hoe, axe, sickle, chemical sprayer, treadle pump, plough, etc. and livestock assets such as cattle, dairy cow, sheep, work oxen, etc.
Change in food security
时间窗: Change in food security between baseline (early stages of intervention), 18-month follow-up (end of intervention), and 36 month follow-up (post-intervention)
