Turkey has successfully introduced health system changes and provided its citizens with the right to health to achieve universal health coverage, which helped to address inequities in financing, health service access, and health outcomes. We trace the trajectory of health system reforms in Turkey, with a particular emphasis on 2003-13, which coinci...

In almost all countries, development of health systems that are responsive to the challenge of prevention and treatment of non-communicable diseases (NCDs) is a priority. NCDs consist of a vast group of conditions, but in terms of premature mortality, emphasis has been on cardiovascular disease, cancer, diabetes, and chronic respiratory diseases—di...
Article
Development assistance for health has increased every year between 2000 and 2010, particularly for HIV/AIDS, tuberculosis, and malaria, to reach US$26·66 billion in 2010. The continued global economic crisis means that increased external financing from traditional donors is unlikely in the near term. Hence, new funding has to be sought from innovat...

Background Adolescents and young adults (AYA) aged 15–24 years account for nearly half of all new HIV infections globally, with over 80% residing in sub-Saharan Africa, where AIDS is a leading cause of death. In Chad, HIV/AIDS significantly impacts AYA, despite a reduction in national prevalence from 1.6% in 2010 to 1.0% in 2022. AYA still contribu...

Introduction Stand-alone HIV clinics in sub-Saharan Africa (SSA) have effectively expanded antiretroviral therapy since the 2000s, transforming HIV from a deadly infection into a chronic condition. However, over the past decade, there has been a significant rise in the prevalence of non-communicable diseases (NCDs) globally and in SSA. People livin...

Full-text available
Despite much research on early detection of anomalies from surveillance data, a systematic framework for appropriately acting on these signals is lacking. We addressed this gap by formulating a hidden Markov-style model for time-series surveillance, where the system state, the observed data, and the decision rule are all binary. We incur a delayed...
Chapter
This second edition of the Oxford Textbook of Community Mental Health addresses recent changes and achievements, current controversies, and future challenges while emphasizing areas of convergence, where social values, health, medical sciences, and policy formation converge and meet. This edition also features a new section on global mental health,...

Background The medical literature has demonstrated that macro-variables and social factors can influence suicide rates. Additionally, social science literature has shown that women in prominent political positions (such as mayors) can influence the behavior of other women. The purpose of our work is to demonstrate that women in such positions reduc...
Article
Background The majority of countries (64%) have an Antimicrobial Resistance (AMR) National Action Plan (NAP V.1.0), but many remain unimplemented, and lack funding for interventions. Intervention selection requires a systematic approach to explain and predict progress. Looking beyond AMR is important to ensure the capture of systemic factors at the...
Article
Full-text available
Maternal mortality remains a large challenge in global health. Learning from the experience of similar countries can help to accelerate progress. In this analysis we develop a typology of country groupings for maternal health and provide guidance on how policy implications vary by country typology. We used estimates from the Global Maternal Health...
Article
Full-text available
Background Financial toxicity is the detrimental impact of health care costs that must be mitigated to achieve universal health coverage. Catastrophic health expenditure (CHE) is widely used to measure financial toxicity but does not capture patient perspectives of unaffordable health care costs. Financial hardship (FH), a patient-reported outcome...

Article
UN member states have committed to universal health coverage (UHC) to ensure all individuals and communities receive the health services they need without suffering financial hardship. Although the pursuit of UHC should unify disparate global health challenges, it is too commonly seen as another standalone initiative with a singular focus on the he...

Background Previous studies of type 1 diabetes in childhood and adolescence have found large variations in reported incidence around the world. However, it is unclear whether these reported incidence levels are impacted by differences in country health systems and possible underdiagnosis and if so, to what degree. The aim of this study was to estim...

Background Historically, the international development community has often held the view that those living in extreme poverty (at less than $1.90/day) are likely to have a low prevalence of cardiovascular disease (CVD) risk factors due to calorie scarcity, a largely plant-based diet, and physical labor. Evidence on CVD risk factor prevalence among...
