poverty effects

Andrés F Henao-Martínez, Kathryn Colborn, Gabriel Parra-Henao
Chagas disease is a complex tropical parasitic infection. It affects a significant portion of the population in Latin America, especially in areas of poverty and poor access to health care. It also affects immigrants in high-income countries who lack access to health care due to their legal status. Millions of people are at risk of contracting the disease, and approximately 30 % of chronically infected patients will develop cardiomyopathy. The cost of caring for patients that have been infected is substantial...

Interventions against neglected tropical diseases (NTD), including lymphatic filariasis (LF), scaled up dramatically after the signing of the London Declaration (LD) in 2012. LF is targeted for elimination by 2020, but some countries are considered not on track to meet the 2020 target using the recommended preventive chemotherapy and morbidity management strategies. In this Opinion article we review the prospects for achieving LF elimination by 2020 in the light of the renewed global action against NTDs and the global efforts to achieve the sustainable development goals (SDGs) by 2030...

OBJECTIVES: Research about the mental health of children in Francophone West Africa is scarce. This paper examines the relationships between adverse childhood experiences, including exposure to violence and exploitation, and mental health outcomes among children living in ultra-poverty in rural Burkina Faso. METHODS: This paper utilizes baseline data collected from 360 children ages 10-15 and 360 of their mothers recruited from twelve impoverished villages in the Nord Region of Burkina, located near the Sahel Desert and affected by extreme food insecurity...

BACKGROUND: Tooth decay is one of the greatest unmet treatment needs among children. Pain and suffering associated with untreated dental disease can lead to problems with eating, speaking, and learning. School-based dental sealant programs (SBSP) deliver a highly effective intervention to prevent tooth decay in children who might not receive regular dental care. SBSPs benefits exceed their costs when they target children at high risk for tooth decay. METHODS: CDC used data from the National Health and Nutrition Examination Survey (NHANES) 2011-2014 to estimate current prevalences of sealant use and untreated tooth decay among low-income (≤185% of federal poverty level) and higher-income children aged 6-11 years and compared these estimates with 1999-2004 NHANES data...

Many national and international institutions advocate approaching violence as a problem in public health and preventive medicine, in a manner similar to the way we address other disabling and life-threatening pathologies such as cancer, diabetes, and heart disease. Prevention by a health model requires an ecological perspective. Previous work has found evidence that economic factors, including unemployment and relative poverty, as well as political culture and values, may affect violent death rates, including homicide and suicide...

Massive slums have become major features of cities in many low-income and middle-income countries. Here, in the first in a Series of two papers, we discuss why slums are unhealthy places with especially high risks of infection and injury. We show that children are especially vulnerable, and that the combination of malnutrition and recurrent diarrhoea leads to stunted growth and longer-term effects on cognitive development. We find that the scientific literature on slum health is underdeveloped in comparison to urban health, and poverty and health...

In the first paper in this Series we assessed theoretical and empirical evidence and concluded that the health of people living in slums is a function not only of poverty but of intimately shared physical and social environments. In this paper we extend the theory of so-called neighbourhood effects. Slums offer high returns on investment because beneficial effects are shared across many people in densely populated neighbourhoods. Neighbourhood effects also help explain how and why the benefits of interventions vary between slum and non-slum spaces and between slums...

Comorbidity of internalizing and externalizing problems and its risk and protective factors have not been well incorporated into developmental research, especially among racial minority youth from high-poverty neighborhoods. The present study identified a latent comorbid factor as well as specific factors underlying internalizing and externalizing problems among 592 African American adolescents living in economically disadvantaged neighborhoods (291 male; M age = 15.9 years, SD = 1.43 years). Stressful life events and racial discrimination were associated with higher comorbid problems, whereas stressful life events and exposure to violence were associated with higher specific externalizing problems...

BACKGROUND: Health expenditure for tuberculosis (TB) care often pushes households into catastrophe and poverty. New Cooperative Medical Scheme (NCMS) aims to protect households from catastrophic health expenditure (CHE) and impoverishment in rural China. This article assesses the effect of NCMS on relieving CHE and impoverishment from TB care in rural China. METHODS: Three hundred fourty-seven TB cases are included in the analysis. We analyze the incidence and intensity of CHE and poverty, and assess the protective effect of NCMS by comparing the CHE and impoverishment before and after reimbursement...

With the exception of a few isolated populations, elevated blood pressure is a worldwide pandemic with staggering consequences for individuals, care givers, health care delivery systems, and insurers, including governments. It is well-recognized that the burden of hypertension and its adverse consequences is greater in low- and middle-income countries than economically developed countries. BP-related outcomes also differ by region, with a predominance of stroke in southeast Asian countries and a predominance of ischemic heart disease in the US and Western Europe...

Chronic kidney disease (CKD) defined as reduced estimated glomerular filtration rate (eGFR) or presence of albuminuria, progresses to end stage renal disease (ESRD), needing dialysis or kidney transplant to sustain life, and is associated with increased risks of premature cardiovascular disease (CVD) and mortality. CKD ranked 18 leading (and most rapidly rising cause of mortality by the Global Burden of Disease Study 2010. The social and economic consequences of CKD are far worse in low and middle income countries (LMICs) including India, Pakistan, Bangladesh, and Sri Lanka...

BACKGROUND: The first policy action outlined in the Sustainable Development Goals (SDGs) is the implementation of national social protection systems. This study assesses whether social protection provision can impact 17 indicators of five key health-related SDG goals amongst adolescents in South Africa. METHODS: We conducted a longitudinal survey of adolescents (10-18 years) between 2009 and 2012. Census areas were randomly selected in two urban and two rural health districts in two South African provinces, including all homes with a resident adolescent...

OBJECTIVE: Although depression among older people is an important public health problem worldwide, systematic studies evaluating its prevalence and determinants in low and middle income countries (LMICs) are sparse. The biopsychosocial model of depression and prevailing socioeconomic hardships for older people in LMICs have provided the impetus to determine the prevalence of geriatric depression; to study its associations with health, social, and economic variables; and to investigate socioeconomic inequalities in depression prevalence in LMICs...

OBJECTIVE: To determine whether race/ethnicity and socioeconomic status are associated with amyotrophic lateral sclerosis (ALS) mortality in the United States. METHODS: The National Longitudinal Mortality Study (NLMS), a United States-representative, multistage sample, collected race/ethnicity and socioeconomic data prospectively. Mortality information was obtained by matching NLMS records to the National Death Index (1979-2011). More than 2 million persons (n = 1,145,368 women, n = 1,011,172 men) were included, with 33,024,881 person-years of follow-up (1,299 ALS deaths , response rate 96%)...

Community water fluoridation is considered a significant public health achievement of the 20th century. In this paper, the hypothesis that added water fluoridation has contributed to diabetes incidence and prevalence in the United States was investigated. Panel data from publicly available sources were used with population-averaged models to test the associations of added and natural fluoride on the outcomes at the county level in 22 states for the years 2005 and 2010. The findings suggest that a 1 mg increase in the county mean added fluoride significantly positively predicts a 0...

The advent of antiretroviral therapy (ART) in 1996 brought with it an urgent need to develop models of health care delivery that could enable its effective and equitable delivery, especially to patients living in poverty. Community-based care, which stretches from patient homes and communities-where chronic infectious diseases are often best managed-to modern health centers and hospitals, offers such a model, providing access to proximate HIV care and minimizing structural barriers to retention. We first review the recent literature on community-based ART programs in low- and low-to-middle-income country settings and document two key principles that guide effective programs: decentralization of ART services and long-term retention of patients in care...

Disorderly environments are linked to disorderly behaviors. Broken windows theory (Wilson & Kelling, 1982), an influential theory of crime and rule-breaking, assumes that scene-level social disorder cues (e.g., litter, graffiti) cause people to reason that they can get away with breaking rules. But what if part of the story is not about such complex social reasoning? Recent research suggests that basic visual disorder cues may be sufficient to encourage complex rule-breaking behavior. To test this hypothesis, we first conducted a set of experiments (Experiments 1-3) in which we identified basic visual disorder cues that generalize across visual stimuli with a variety of semantic content...

Tropical wetlands are highly threatened socio-ecological systems, where local communities rely heavily on aquatic animal protein, such as fish, to meet food security. Here, we quantify how a 'win-win' community-based resource management program induced stock recovery of the world's largest scaled freshwater fish (Arapaima gigas), providing both food and income. We analyzed stock assessment data over eight years and examined the effects of protected areas, community-based management, and landscape and limnological variables across 83 oxbow lakes monitored along a ~500-km section of the Juruá River of Western Brazilian Amazonia...

OBJECTIVE: Although numerous studies have documented the effects of sleep loss on executive control (EC) and related abilities, research examining the impact of early EC on subsequent sleep problems is lacking. Therefore, the current study reports on a longitudinal investigation of EC in preschool as a predictor of sleep-wake problems and daytime sleepiness in early adolescence. PARTICIPANTS: The participants were 141 children (48.6% female) recruited from the community for a longitudinal study spanning preschool through early adolescence, with an oversampling for high sociodemographic risk (34...

PURPOSE: Neglected tropical diseases (NTDs) affect people living in the poorest regions of the world and their debilitating effects perpetuate the poverty cycle. Understanding the distribution of NTDs is crucial for effective intervention delivery. In 2012, the Global Trachoma Mapping Project (GTMP) was initiated to map >1800 suspected trachoma endemic districts by March 2015. This research was carried out to better understand the implementation experience and identify lessons which might inform the GTMP and similar initiatives...
