Many Latinx and Indigenous Mexican populations in the United States Southwest live in unincorporated communities in the US-Mexico borderlands called colonias. These environmental justice communities often lack basic infrastructure, including healthcare services, prompting many to seek services across the border. However, due to geopolitical factors more vulnerable caregivers are limited to utilize healthcare services in the US. This paper reports the experiences and healthcare decision-making of caregivers living in colonias in the US-Mexico border region who care for children with respiratory health conditions. This study was carried out from September to December 2020. Focus groups and interviews were conducted with Latinx and Indigenous Mexican caregivers of children with asthma or respiratory distress. Qualitative interviews elicited caregivers' perspectives on the environmental factors affecting children's chronic health conditions and use of healthcare services. The analysis employed the concept of structure vulnerability to theorize geography as a structural determinant of health for caregivers faced with making healthcare decisions for their suffering from respiratory health conditions. A survey was administered to collect basic sociodemographic information. A total of 36 caregivers participated in the study. Structural factors including unincorporated community status and government inaction intersected with social determinants of health to prompt caregivers to cross the US-Mexico border to access healthcare services in Mexico for their children. Yet, more vulnerable caregivers (i.e., those without documentation status in the US) and their children, accessing healthcare services in the US was not an option limiting caregivers' ability to meet their children's healthcare needs. In such cases, geography acts as a structural determinant of health. This study shows the importance of geography in health. Rural unincorporated colonias located in the borderlands are precariously located and lack basic critical infrastructure including healthcare access. Within such places, historically and socially marginalized populations become invisible, are subject to the health effects of environmental hazards, and are limited depending on their positionality and thus vulnerability to healthcare services. • Municipal unincorporation contributes to health disparities among Latinx families in US-Mexico borderlands. • Latinx children in colonias are disproportionately exposed to environmental toxins. • Geography acts as a structural determinant of health for Latinx families in colonias. • A binational approach to health services should be prioritized for families in the borderlands.

Health insurance is one of the main financing mechanisms currently being used in low and middle-income countries to improve access to quality services. Tanzania has been running its National Health Insurance Fund (NHIF) since 2001 and has recently undergone significant reforms. However, there is limited attention to the causal mechanisms through which NHIF improves service coverage and quality of care. This paper aims to use a system dynamics (qualitative) approach to understand NHIF causal pathways and feedback loops for improving service coverage and quality of care at the primary healthcare level in Tanzania. We used qualitative interviews with 32 stakeholders from national, regional, district, and health facility levels conducted between May to July 2021. Based on the main findings and themes generated from the interviews, causal mechanisms, and feedback loops were created. The majority of feedback loops in the CLDs were reinforcing cycles for improving service coverage among beneficiaries and the quality of care by providers, with different external factors affecting these two actions. Our main feedback loop shows that the NHIF plays a crucial role in providing additional financial resources to facilities to purchase essential medical commodities to deliver care. However, this cycle is often interrupted by reimbursement delays. Additionally, beneficiaries' perception that lower-level facilities have poorer quality of care has reinforced care seeking at higher-levels. This has decreased lower level facilities' ability to benefit from the insurance and improve their capacity to deliver quality care. Another key finding was that the NHIF funding has resulted in better services for insured populations compared to the uninsured. To increase quality of care, the NHIF may benefit from improving its reimbursement administrative processes, increasing the capacity of lower levels of care to benefit from the insurance and appropriately incentivizing providers for continuity of care. • The NHIF influences service coverage and quality in complex ways. • NHIF reimbursement is crucial for facilities and its delay affects inputs for quality. • Lower levels of care benefit less from NHIF. • Need to improve reimbursement process to enhance quality of care.

Abstract: In recent years, Kazakhstan has become an important destination for primarily undocumented seasonal workers from Uzbekistan. In a context of high tuberculosis (TB) incidence, TB treatment is provided free for all residents in Kazakhstan, but migrants rarely access these services. This paper reports findings from a qualitative study conducted with migrants, TB patients and health care workers between July and September 2008 to understand the mechanisms that impede migrants’ access to care. Findings describe three structural contexts – the employment, legal and health care contexts – which act in concert to render migrants vulnerable to exploitative work conditions and cause a series of barriers to health care. These conditions contribute to increased exposure to TB, heightened risk of reactivation due to weakened immunity, treatment-seeking delays, and increased severity of disease. Seasonal migration patterns also contribute to treatment interruption, which constitutes a risk for the creation of drug resistance. Using the theory of structural violence coupled with the concept of cumulative vulnerability, this paper analyzes how illegality interacts with exploitation and social marginalization to produce vulnerability to TB and restrict access to treatment.
