RESUMO

Objectives. To estimate the impact of communicating to the public that men who have sex with men (MSM) are most at risk for mpox on potential stigmatization and risk perception. Methods. We conducted a survey experiment randomizing exposure to messages about mpox among a sample of the South Korean public (n = 1500) in July 2022. We randomized respondents to receive an informational message about mpox that was (1) a neutral informational message about mpox that did not highlight its origins or risk groups (control group), (2) a message explaining that the virus originated in Africa, or (3) a message emphasizing that MSM are most at risk. Results. We found that emphasizing that MSM are most at risk increases support for policies that would restrict lesbian, gay, bisexual, transgender/-sexual, queer or questioning-related events by about 7 percentage points compared with the control condition. However, the message describing African origins did not affect support for restricting travel from Africa. Neither changed risk perceptions or willingness to be vaccinated against mpox. Conclusions. Messages aimed at educating the public about most at-risk groups may trigger increased stigmatization of those groups in ways that could contribute to unnecessary persecution.

RESUMO

OBJECTIVES: To examine the relationship between adolescent pregnancy-prevention and sexuality and abstinence-only education funding and adolescent birthrates over time. Also, to determine whether state ideology plays a moderating role on adolescent reproductive health, that is, whether the funding has its intended effect at reducing the number of adolescent births in conservative but not in liberal states. METHODS: We modeled time-series data on federal abstinence-only and adolescent pregnancy-prevention and sexuality education block grants to US states and rates of adolescent births (1998-2016) and adjusted for state-level confounders using 2-way fixed-effects models. RESULTS: Federal abstinence-only funding had no effect on adolescent birthrates overall but displayed a perverse effect, increasing adolescent birthrates in conservative states. Adolescent pregnancy-prevention and sexuality education funding eclipsed this effect, reducing adolescent birthrates in those states. CONCLUSIONS: The millions of dollars spent on abstinence-only education has had no effect on adolescent birthrates, although conservative states, which experience the greatest burden of adolescent births, are the most responsive to changes in sexuality education-funding streams.

RESUMO

Policy Points: For more than 3 decades, international development agencies have advocated health system decentralization to improve health system performance in low- and middle-income countries. We found little rigorous evidence documenting the impact of decentralization processes on health system performance or outcomes in part due to challenges in measuring such far-reaching and multifaceted system-level changes. We propose a renewed research agenda that focuses on discrete definitions of decentralization and how institutional factors and mechanisms affect health system performance and outcomes within the general context of decentralized governance structures. CONTEXT: Despite the widespread adoption of decentralization reforms as a means to improve public service delivery in developing countries since the 1980s, empirical evidence of the role of decentralization on health system improvement is still limited and inconclusive. This study reviewed studies published from 2000 to 2016 with adequate research designs to identify evidence on whether and how decentralization processes have impacted health systems. METHODS: We conducted a systematic review of peer-reviewed journal articles from the public health and social science literature. We searched for articles within 9 databases using predefined search terms reflecting decentralization and health system constructs. Inclusion criteria were original research articles, low- and middle-income country settings, quantifiable outcome measures, and study designs that use comparisons or statistical adjustments. We excluded studies in high-income country settings and/or published in a non-English language. FINDINGS: Sixteen studies met our prespecified inclusion and exclusion criteria and were grouped based on outcomes measured: health system inputs (n = 3), performance (n = 7), and health outcomes (n = 7). Numerous studies addressing conceptual issues related to decentralization but without any attempt at empirical estimation were excluded. Overall, we found mixed results regarding the effects of decentralization on health system indicators with seemingly beneficial effects on health system performance and health outcomes. Only 10 studies were considered to have relatively low risks of bias. CONCLUSIONS: This study reveals the limited empirical knowledge of the impact of decentralization on health system performance. Mixed empirical findings on the role of decentralization on health system performance and outcomes highlight the complexity of decentralization processes and their systemwide effects. Thus, we propose a renewed research agenda that focuses on discrete definitions of decentralization and how institutional factors and mechanisms affect health system performance and outcomes within the general context of decentralized governance structures.

RESUMO

Exposure to nicotine alters the trafficking and assembly of nicotinic receptors (nAChRs), leading to their up-regulation on the plasma membrane. Although the mechanism is not fully understood, nicotine-induced up-regulation is believed to contribute to nicotine addiction. The effect of cotinine, the primary metabolite of nicotine, on nAChR trafficking and assembly has not been extensively investigated. We utilize a pH-sensitive variant of GFP, super ecliptic pHluorin, to differentiate between intracellular nAChRs and those expressed on the plasma membrane to quantify changes resulting from cotinine and nicotine exposure. Similar to nicotine, exposure to cotinine increases the number of α4ß2 receptors on the plasma membrane and causes a redistribution of intracellular receptors. In contrast to this, cotinine exposure down-regulates α6ß2ß3 receptors. We also used single molecule fluorescence studies to show that cotinine and nicotine both alter the assembly of α4ß2 receptors to favor the high sensitivity (α4)2(ß2)3 stoichiometry.

RESUMO

Objectives To examine relationships between parental perceptions of child weight and overall health, reported lifestyle behaviors and measured body mass index (BMI). Methods Using community-partnered methods, we surveyed families residing in a two census tract area identified for targeted interventions to decrease diabetes related disparities. The survey included demographics, child dietary and physical activity behaviors, and parental perception of child's health and weight. We measured child BMI using a standardized protocol. Results We surveyed parents of 116 children with a mean age of 7 years (range 3-15) with 51 % boys, 74 % Hispanic, and 26 % Black. Over half of the children (55 %) were overweight or obese. Half (50 %) of the parents underestimated their children's weight. Reported daily hours of walking and/or running trended higher (3.6 vs. 2.6 h, p = 0.08) for children perceived to be of normal weight. Parents who correctly estimated their child's weight status reported more hours of daily walking/running than parents who underestimated child weight status, 4.5 versus 2.4 h, p = 0.0002. Parents of healthy weight children were more likely to report that children were in excellent or very good health compared to parents of overweight/obese children, 75 versus 56 % respectively (p = 0.04). We found significant racial/ethnic differences in reported diet and physical activity behaviors and perception of overall health. Conclusions for Practice Parental perceptions of child health and physical activity level may be related to perceptions of their child's weight status. Study findings informed community-based initiatives for reducing diabetes risk among children.

RESUMO

Universal health coverage has recently become a top item on the global health agenda pressed by multilateral and donor organizations, as disenchantment grows with vertical, disease-specific health programs. This increasing focus on universal health coverage has brought renewed attention to the role of domestic politics and the interaction between domestic and international relations in the health reform process. This article proposes a theory-based framework for analyzing the politics of health reform for universal health coverage, according to four stages in the policy cycle (agenda setting, design, adoption, and implementation) and four variables that affect reform (interests, institutions, ideas, and ideology). This framework can assist global health policy researchers, multilateral organization officials, and national policy makers in navigating the complex political waters of health reforms aimed at achieving universal health coverage. To derive the framework, we critically review the theoretical and applied literature on health policy reform in developing countries and illustrate the framework with examples of health reforms moving toward universal coverage in low- and middle-income countries. We offer a series of lessons stemming from these experiences to date.

RESUMO

In May 2011, a year after the passage of the Affordable Care Act (ACA), Vermont became the first state to lay the groundwork for a single-payer health care system, known as Green Mountain Care. What can other states learn from the Vermont experience? This article summarizes the findings from interviews with nearly 120 stakeholders as part of a study to inform the design of the health reform legislation. Comparing Vermont's failed effort to adopt single-payer legislation in 1994 to present efforts, we find that Vermont faced similar challenges but greater opportunities in 2010 that enabled reform. A closely contested gubernatorial election and a progressive social movement opened a window of opportunity to advance legislation to design three comprehensive health reform options for legislative consideration. With a unified Democratic government under the leadership of a single-payer proponent, a high-profile policy proposal, and relatively weak opposition, a framework for a single-payer system was adopted by the legislature - though with many details and political battles to be fought in the future. Other states looking to reform their health systems more comprehensively than national reform can learn from Vermont's design and political strategy.

RESUMO

A new approach is presented for the application of single-molecule imaging to membrane receptors through the use of vesicles derived from cells expressing fluorescently labeled receptors. During the isolation of vesicles, receptors remain embedded in the membrane of the resultant vesicles, thus allowing these vesicles to serve as nanocontainers for single-molecule measurements. Cell-derived vesicles maintain the structural integrity of transmembrane receptors by keeping them in their physiological membrane. It was demonstrated that receptors isolated in these vesicles can be studied with solution-based fluorescence correlation spectroscopy (FCS) and can be isolated on a solid substrate for single-molecule studies. This technique was applied to determine the stoichiometry of α3ß4 nicotinic receptors. The method provides the capability to extend single-molecule studies to previously inaccessible classes of receptors.

RESUMO

Research has identified sexual concurrency as a potential underlying driver of high HIV infection levels in sub-Saharan Africa, though few studies have explicitly examined the contribution of marital concurrency. Utilizing a multi-level model of Demographic and Health Surveys with HIV-biomarkers for sixteen African countries, this study assessed the relationship between an individual's HIV serostatus and rates of formal and informal marital concurrency (% polygamous unions, % extramarital partner past year) among married men and women. Mutually exclusive regional-level variables were constructed and modeled to test the contextual risk posed by living in a region with higher levels of formal and informal marital concurrency controlling for individual sexual partnerships and other covariates. Compared with regions where monogamous unions were more prevalent, the odds of having HIV were higher among individuals living in regions with more informal marital concurrency, but lower in regions with more polygamy, even accounting for individual-level sexual behavior. These results can help inform prevention policy and practice in sub-Saharan Africa.

RESUMO

INTRODUCTION: In 2008, the New York City (NYC) health department licensed special mobile produce vendors (Green Carts) to increase access to fruits and vegetables in neighborhoods with the lowest reported fruit and vegetable consumption and the highest obesity rates. Because economic incentives may push vendors to locate in more trafficked, less produce-deprived areas, we examined characteristics of areas with and without Green Carts to explore whether Carts are positioned to reach the intended populations. METHODS: Using ArcGIS software, we mapped known NYC Green Cart locations noted through 2013 and generated a list of potential (candidate) sites where Carts could have located. We compared the food environment (via categorizing "healthy" or "unhealthy" food stores using federal classification codes corroborated by online storefront images) and other factors that might explain Cart location (eg, demographic, business, neighborhood characteristics) near actual and candidate sites descriptively and inferentially. RESULTS: Seven percent of Green Carts (n = 265) were in food deserts (no healthy stores within one-quarter mile) compared with 36% of candidate sites (n = 644, P < .001). Most Carts (78%) were near 2 or more healthy stores. Green Carts had nearly 60 times the odds of locating near subway stops (P < .001), were closer to large employers (odds ratio [OR], 6.4; P < .001), other food stores (OR, 14.1; P < .001), and in more populous tracts (OR, 2.9, P <.01) compared with candidate sites. CONCLUSION: Green Carts were rarely in food deserts and usually had multiple healthy stores nearby, suggesting that Carts may not be serving the neediest neighborhoods. Exploration of Carts' benefits in non-food desert areas is needed, but incentivizing vendors to locate in still-deprived places may increase program impact.

RESUMO

At its core, political economy analysis involves examination of the relationship between the state and the market. A number of country case studies have emerged in recent years that aim to identify political economy factors facilitating or impeding health sector reforms towards universal coverage. In this commentary, we expand Nannini and colleagues' analysis to elaborate on how political economy analyses can better inform policy design towards more successful reforms in low- and middle-income countries (LMICs) by drawing more heavily on improved research design and theory. We suggest three ways that political economy studies could make deeper claims by historicizing analyses, going comparative and/or by grounding findings more deeply in theory.

RESUMO

OBJECTIVE: To buffer the economic impacts of the pandemic-induced economic downturns, the U.S. government passed major economic stimulus bills that provided cash payments to affected citizens and a large boost to unemployment benefits. We ask what impact these enhanced safety-net policies have had on mental health and stress-induced substance use among low-income Americans, especially enhanced unemployment insurance (UI) benefits, which constituted a large economic transfer to those eligible. METHODS: Using individual fixed effects analysis of a panel of nearly 900 low-income Americans since the start of the pandemic from the Understanding America Survey, we examine how receipt of enhanced unemployment benefits has impacted the mental health burden and substance use behaviors of low-income Americans. We additionally examine the buffering effect of a set of other safety-net measures (Stimulus, Medicaid, SNAP, TANF, housing assistance, EITC, WIC, and CHIP). RESULTS: We found that job loss, regardless of benefit receipt, was associated with increased stress and decreased average substance use, driven by reduced smoking when compared with those were employed. Yet, when factoring in UI receipt we see that receiving UI was associated with reduced stress, but no impact on depression or substance use. In contrast, those who did not receive UI experienced greater stress compared with those who were employed. Overall, we found that people who remained employed used substances more than people who were unemployed regardless of UI receipt with the exception of drinking. CONCLUSIONS: We conclude that enhanced unemployment offset some of the negative mental health effects of the pandemic and did not increase routine substance use among the unemployed.

RESUMO

The two primary narratives that have emerged to explain low COVID-19 vaccine uptake in low- and middle-income countries are constrained accessibility and vaccine hesitancy. However, it is unclear how much each issue contributes to low uptake. This article examines these twin barriers to access. Using global survey data from 15,696 respondents across seventeen Western Pacific and African countries, collected between May 2022 and January 2023, we estimated the unmet demand for vaccines and examined its predictors. We found that among unvaccinated respondents, by the time of the survey, 50 percent had unmet demand-meaning they were still willing to get vaccinated. Rates of unmet demand were highest in African countries and lowest in Western Pacific countries. The perceived accessibility of vaccines and respondents' age and sex were identified as consistent predictors of unmet demand. These issues suggest that inequitable supply continues to play a substantial role in limiting vaccine access. Targeted efforts to increase vaccination rates are necessary, particularly in countries with low coverage and high unmet demand. Policy efforts should address barriers to vaccine access, ensure accessibility and distribution of mRNA vaccines, and aim to overcome vaccine hesitancy-all critical factors in reducing unmet immunization demand and achieving higher vaccination rates across regions.

RESUMO

INTRODUCTION: It is increasingly recognized that regular boosters will be necessary for the continued management of the COVID-19 pandemic. While vaccine hesitancy in the context of the initial COVID-19 vaccinations has been extensively studied, less is known about hesitancy around boosters in the post-pandemic era, where the immediate threat of COVID-19 has diminished. METHODS: Using 5,584 survey responses from people who had received at least one COVID-19 vaccine dose based on a four-round survey between May and November 2022, we examined various factors that affect booster vaccine uptake and the willingness to take an additional shot. Ordinary least squares regressions were conducted to confirm the statistical significance of the findings. RESULTS: Nearly 99% of vaccinated respondents reported having had two COVID-19 vaccine doses, while 69% of respondents reported having received a booster shot (three or more vaccine doses) and 48% reported being willing to get another shot. Booster uptake was strongly increased along with the degree of trust in the Korean Disease Control Agency (KDCA) and was also significantly associated with older age, gender, political propensity, and household income-level. When examining willingness to get an additional shot, the predictors were similar to booster vaccine uptake. However, the effect of trust in the KDCA became more salient. CONCLUSION: The factors associated with booster uptake and willingness to continue to boost are similar to those associated with initial vaccine acceptance in the ROK, namely trust in the public health authority and older age. Despite high initial uptake in the ROK, convincing the public of the continued necessity of routine immunization against COVID-19 may pose challenges in the post-pandemic era.

RESUMO

OBJECTIVES: National political commitment is likely to become particularly crucial to sustaining antiretroviral treatment programmes in the coming decade, as donor contributions to HIV funding decreases. The objective of this study is to synthesise information on existing indicators of political commitment to respond to national HIV epidemics. METHODS: The authors describe and critically evaluate the existing indicators and propose studies to validate them. RESULTS: Several indicators have been developed to measure governments' political commitment to respond to national HIV epidemics--the AIDS Program Effort Index, the United Nations General Assembly Special Session on HIV/AIDS Declaration of Commitment Indicators and the AIDS Policy Aggressiveness Indicators--but the validity of these measures has not been systematically assessed. The indicators differ in their intended use, collection methods, content categories, data coverage, and strengths and limitations. Several types of studies could be used to test indicator validity (based on indicator content, comparisons of the same indicator using different elicitation methods, relationship patterns between indicators, relations between indicators and other variables and the consequences of using the indicators). CONCLUSIONS: The existing indicators of political commitment to respond to national HIV epidemics are useful for many purposes, including research, policymaking and advocacy. A range of studies could improve the understanding of indicator validity. New data collection and measurement approaches offer opportunities to improve how actors in the HIV community capture the complicated, multidimensional concept of political commitment.

RESUMO

Although health is generally believed to improve with higher wealth, research on HIV in sub-Saharan Africa has shown otherwise. Whereas researchers and advocates have frequently advanced poverty as a social determinant that can help to explain sub-Saharan Africa's disproportionate burden of HIV infection, recent evidence from population surveys suggests that HIV infection is higher among wealthier individuals. Furthermore, wealthier countries in Africa have experienced the fastest growing epidemics. Some researchers have theorized that inequality in wealth may be more important than absolute wealth in explaining why some countries have higher rates of infection and rapidly increasing epidemics. Studies taking a longitudinal approach have further suggested a dynamic process whereby wealth initially increases risk for HIV acquisition and later becomes protective. Prior studies, conducted exclusively at either the individual or the country level, have neither attempted to disentangle the effects of absolute and relative wealth on HIV infection nor to look simultaneously at different levels of analysis within countries at different stages in their epidemics. The current study used micro-, meso- and macro-level data from Demographic and Health Surveys (DHS) across 170 regions within sixteen countries in sub-Saharan Africa to test the hypothesis that socioeconomic inequality, adjusted for absolute wealth, is associated with greater risk of HIV infection. These analyses reveal that inequality trumps wealth: living in a region with greater inequality in wealth was significantly associated with increased individual risk of HIV infection, net of absolute wealth. The findings also reveal a paradox that supports a dynamic interpretation of epidemic trends: in wealthier regions/countries, individuals with less wealth were more likely to be infected with HIV, whereas in poorer regions/countries, individuals with more wealth were more likely to be infected with HIV. These findings add additional nuance to existing literature on the relationship between HIV and socioeconomic status.

RESUMO

Has political polarization undermined the media' informational role during the COVID-19 pandemic? Recent studies show that politicized reporting from conservative media discouraged compliance with COVID-19 guidelines in the U.S. However, greater attention to the 24-hour news cycle may make high-consumption viewers better factually informed regardless of the source. We examine how the extent of media consumption affects people's emotions, attitudes, and behaviors toward the pandemic. With an online survey of 1128 respondents, we found a strong convergence in anxiety and health-protective behaviors in more avid media viewers regardless of media outlet while finding a divergence in attitudes toward specific mitigation strategies.

RESUMO

STUDY GOAL: This study examines the sources of COVID-19 vaccine hesitancy and refusal in Americans by decomposing different forms of government trust/mistrust including trust in Trump and mistrust in public health institutions. METHODS: Using linear panel regression models with data from 5,446 US adults (37,761 responses) from the Understanding America Survey, the likelihoods of vaccine hesitancy, uptake, and trust in various information sources were examined. RESULTS AND CONCLUSION: We find that the likelihoods of hesitancy and having negative perceptions of COVID-19 vaccines were consistently much higher among PHI mistrusters, showing even a stronger hesitancy than Trump trusters. This tendency has persisted over time, resulting in only 49% of PHI mistrusters having been vaccinated in the most recent survey wave. However, a large portion of PHI mistrusters still trusted physicians, family, and friends. These findings suggest that mistrust in PHIs is a salient predictor of vaccine hesitancy and reduced uptake on its own, which is compounded by trust in Trump.

RESUMO

ABSTRACTAlthough the excess male mortality from COVID-19 is well-known, the variations in sex gaps in incidence and mortality across countries and the sources of such variations are not well understood. This study explored the patterns and the sources of variation in the sex gap in COVID-19 incidence and mortality rates across 100 countries where sex-disaggregated cases and deaths were available as of September 2020. Our results show that there is generally a male disadvantage in both incidence and mortality; however, COVID-19 incidence exhibited a lower male disadvantage (1.2 times higher risk for males) than COVID-19 mortality (1.5 times higher risk for males). The extent of male disadvantages in COVID-19 outcomes across countries varied by societal gender inequalities and behavioural factors. Greater gender equality, both socially and behaviourally, was associated with more equal COVID-19 incidence and mortality between men and women. The findings imply that male disadvantages in COVID-19 outcomes, particularly incidence, are socially determined, whereas further investigation is needed to understand behavioural and biological elements yielding a male disadvantage in mortality.

RESUMO

The relationship between intimate partner violence (IPV) and HIV risk is well documented, but few interventions jointly address these problems. We developed and examined the feasibility of an intervention to reduce HIV risk behaviors among 97 women seeking services for IPV from a community-based NGO in Johannesburg, South Africa. Two versions of the intervention (a 6-session group and a 1-day workshop) were implemented, both focusing on HIV prevention strategies integrated with issues of gender and power imbalance. Attendance was excellent in both intervention groups. Assessments were conducted at baseline, post-intervention and two-month follow-up to demonstrate the feasibility of an intervention trial. Women in both groups reported reductions in HIV misperceptions and trauma symptoms, and increases in HIV knowledge, risk reduction intentions, and condom use self-efficacy. The 6-session group showed greater improvements in HIV knowledge and decreases in HIV misperceptions in comparison to the 1-day workshop. The study demonstrated the feasibility and potential benefit of providing HIV prevention intervention to women seeking assistance for IPV.
