RESUMO
Global environmental crises demand scaled-up investment in education about planetary health. We identified college and university programs in the United States that focus on the human-animal-ecosystem nexus by systematically searching the 2023-2024 catalogs of more than 1000 schools. We identified four frequently-used curricular models: (1) One Health programs offered by universities with veterinary and agriculture schools that emphasize zoonotic diseases, antimicrobial resistance, food safety, and wildlife conservation; (2) climate change and health (climate medicine) programs for graduate and professional students at large universities with medical and public health schools; (3) global environmental public health programs focused on pollution and other exposures; and (4) sustainability and health programs emphasizing food security, environmental justice, and other health issues that can be improved with ethical design and engineering. Highlighting the shared goals of these distinct academic models may help make planetary health a more visible area of teaching, research, and practice.
RESUMO
BACKGROUND: The 2020 World Health Organization Guidelines on Physical Activity and Sedentary Behavior are the first to provide evidence-based recommendations for reducing both dimensions of languorous behavior. The relationship between sitting time and exercise remains understudied among diverse adolescent populations worldwide. METHODS: The 2017 Sierra Leone Global School-based Student Health Survey was a nationally representative cross-sectional study of secondary school students. RESULTS: Of the 2798 participants, 82% did not engage in moderate or vigorous physical activity for at least an hour every day, 25% sat for 3 or more hours each day outside of school and homework, and 87% were physically inactive and/or sedentary based on those thresholds. Girls who never or rarely exercised tended to maintain light physical activity outside of school rather than sitting, while boys who exercised daily tended to be sedentary when they were not playing sports. IMPLICATIONS FOR SCHOOL HEALTH POLICY, PRACTICE, AND EQUITY: Students spend their waking hours doing a mix of sitting, light physical activity, and moderate or vigorous physical activity. Schools can help reduce sedentarism and increase movement among students. CONCLUSIONS: Home, school, and community health interventions may be useful for increasing energy expenditure among adolescents in low- and middle-income countries.

OBJECTIVE: To assess knowledge, attitudes, and practices (KAP) related to antimicrobial resistance (AMR) among college students. PARTICIPANTS: Undergraduate students at a large public university in the United States. METHODS: Anonymous online questionnaire completed in early 2020. RESULTS: While 82% of participants knew that resistant pathogens can spread between people, 38% believed that antibiotics weaken the immune system and 32% believed that AMR is only a problem for people who take antibiotics often. Many undergraduates have or would stop taking antibiotics before completing a full course because of side effects (44%) or feeling better (38%), and some would take (23%) or share (13%) antibiotics that had not been prescribed to the recipient. Only 57% are worried about AMR, compared to 88% who are worried about global climate change. CONCLUSIONS: Health education about antimicrobial stewardship and other global health issues must improve knowledge, perceptions, health behaviors, self-efficacy, and social norms.
RESUMO
Loiasis, also called African eye worm, is not currently on WHO's list of priority neglected tropical diseases, even though the risk that individuals with high Loa loa microfilarial densities will develop potentially fatal encephalopathy when they take ivermectin has complicated efforts to use mass drug administration for onchocerciasis (river blindness) and lymphatic filariasis control in co-endemic areas. At least 10 million residents of central and west Africa are thought to have loiasis, which causes painful and itchy subcutaneous oedema, arthralgia, and discomfort when adult helminths that are 3-7 cm in length are present under the conjunctiva of the eye. High levels of microfilaraemia are associated with renal, cardiac, neurological, and other sequelae, and an increased risk of death. The public health burden of loiasis could be greatly reduced with expanded use of diagnostic tests, anthelmintic treatment, and control of the Chrysops spp (tabanid flies) vectors that transmit the parasite. Loiasis should be added to the next revision of the WHO neglected tropical disease priority list, not merely because its inclusion will support the elimination of other skin and subcutaneous neglected tropical diseases, but also because of the complications caused by loiasis itself.

PURPOSE: High rates of adolescent physical inactivity and sedentary behavior have been reported worldwide, but the combined prevalence of languorous behavior (physical inactivity and/or sedentary behavior) may more accurately reflect just how few adolescents meet World Health Organization recommendations. METHODS: We analyzed nationally representative data from 325,219 students in 80 countries that participated in the Global School-based Student Health Survey between 2009 and 2018. Students were classified as physically inactive if they reported engaging in moderate or vigorous physical activity less than 60 minutes daily. Students were classified as being sedentary if they sat for three or more hours per day outside of school, such as when having screen time not related to studying. Statistics for each country were generated using complex samples analysis, then the results from all countries were synthesized. RESULTS: In total, 84% of students were physically inactive, 37% were sedentary, and 91% met the definition for the concept we are calling languorous behavior. DISCUSSION: Establishing specific evidence-based guidelines for increasing physical activity and decreasing sitting time will enable progress toward reducing languorous behavior among adolescents.

The coronavirus pandemic has imposed extraordinary demands on the public and environmental health workforce, including those who work on vector-borne disease (VBD) prevention and control. In late 2021, we surveyed more than 100 applied public health professionals, academic researchers, and others working on VBDs in the United States. They reported that the supply chain disruptions and limited access to facilities that impeded laboratory work in the early months of the COVID-19 pandemic in 2020 have largely resolved. However, many public health personnel across job types and career stages are still working fewer hours on VBDs than they did before the pandemic. Many reported that they expect it to take several years for VBD specialists to fully reengage with clinicians and the public, reinvigorate their partnerships and professional networks, and recover from interruptions to work productivity and professional development. Despite these challenges, most applied and academic VBD workers remain enthusiastic about their work and eager to advance this important area of infectious disease research and practice.
RESUMO
Global health degree programs are now offered by institutions of higher education in most world regions. Based on our review of the curricula for many of these programs, we identified five domains that are central to current global health education. "Parity" emphasizes health equity as the ultimate goal of global health. "People" comprises the social, economic, cultural, and political contributors to health and access to medical care for individuals and communities. "Planet" encompasses various aspects of globalization and environmental health that affect population health. "Priorities" and "practices" include the values, data, and tools used to design, implement, and evaluate partnerships, policies, programs, and other global health interventions in countries of all income levels. The pandemic is likely to increase student demand for global health education from the undergraduate through the graduate and professional levels. Our "5 Ps model of global health education" provides a comprehensive framework for the core student learning objectives for global health today. Knowledge of each of these domains is essential for preparing students for meaningful experiential learning and skilled professional practice in global health.

Background: Anxiety disorders are common among adolescents. In high-income countries, anxiety is a known contributor to truancy and school refusal, but this association has been understudied in low- and middle-income countries (LMICs). Methods: We used complex samples analysis to examine the association between self-reported worry-induced insomnia (an indicator of anxiety) and unauthorized school absenteeism among 268,142 adolescents from 69 LMICs that participated in the Global School-based Student Health Survey (GSHS). Results: The median proportion of students who reported experiencing symptoms of anxiety most or all of the time during the previous year was 11.4% (range: 3.6%-28.2%); in 44 of the 69 countries, girls had a significantly higher prevalence of anxiety than boys. The percentage of students reporting school absence without permission during the past month was 30.2% (range: 14.7%-56.0%); in 40 countries, boys were significantly more likely than girls to report that they had missed school without permission. In 53 countries, adolescents who reported frequent anxiety were significantly more likely to miss school than adolescents reporting infrequent anxiety; in most of those countries, the association was significant for both girls and boys. Conclusion: School-based interventions that help children and adolescents learn how to manage stress and refer students with symptoms of psychiatric disorders to healthcare services that can provide formal diagnosis and clinical treatment may be useful for improving both mental health and school attendance, thus contributing to achievement of Sustainable Development Goals related to both health (SDG 3.4) and education (SDG 4.1).
RESUMO
BACKGROUND: Malaria transmission-blocking vaccines (TBVs) could help break the cycle of malaria transmission by conferring community rather than individual protection. When introducing new intervention strategies, uptake is dependent on acceptability, not just efficacy. In this exploratory study on acceptability of TBVs in Sierra Leone, it was hypothesized that TBVs would be largely acceptable to adults and health workers in areas with relatively few ongoing malaria interventions, and that (i) knowledge of malaria and vaccines, (ii) health behaviours associated with malaria and vaccines, and (iii) attitudes towards different vaccines types could lead to greater TBV acceptability. METHODS: This study used a mixed methods approach in Bo, Sierra Leone, to understand community knowledge, attitudes, and practices related to malaria and vaccination in general. This included: (i) a population-based cross-sectional survey (n=615 adults), (ii) 6 focus group discussions with parents, and (iii) 20 key informant interviews. The concept of a TBV was explained to participants before they were asked about their willingness to accept this vaccine modality as part of an integrated malaria elimination programme. RESULTS: This study found that most adults would be willing to receive a TBV vaccine. Respondents noted mostly positive past experiences with adult and childhood vaccinations for other infectious diseases and high levels of engagement in other malaria prevention behaviors such as bed nets. Perceived barriers to TBV acceptance were largely focused on general community-level distribution of a vaccine, including personal fears of vaccination and possible costs. After an explanation of the TBV mechanism, nearly all focus group and interview participants believed that community members would accept the vaccine as part of an integrated malaria control approach. Both parents and health workers offered insight on how to successfully roll-out a future TBV vaccination programme. CONCLUSIONS: The willingness of community members in Bo, Sierra Leone to accept a TBV as part of an integrated anti-malarial strategy suggests that the atypical mechanism of TBV action might not be an obstacle to future clinical trials. This study's findings suggests that perceived general barriers to vaccination implementation, such as perceived personal fears and vaccine cost, must be addressed in future clinical and implementation research studies.

BACKGROUND: Rapid and sensitive diagnostics are critical tools for clinical case management and public health control efforts. Both capillary and venous blood are currently used for malaria detection and while diagnostic technologies may not be equally sensitive with both materials, the published data on this subject are scarce and not conclusive. METHODS: Paired clinical samples of venous and capillary blood from 141 febrile individuals in Bo, Sierra Leone, were obtained between January and May 2019 and tested for the presence of Plasmodium parasites using two multiplexed PCR assays: the FilmArray-based Global Fever Panel (GFP) and the TaqMan-based Malaria Multiplex Sample Ready (MMSR) assay. RESULTS: No significant differences in Plasmodium parasite detection between capillary and venous blood for both assays were observed. The GFP assay was more sensitive than MMSR for all markers that could be compared (Plasmodium spp. and Plasmodium falciparum) in both venous and capillary blood. CONCLUSIONS: No difference was found in malaria detection between venous and capillary blood using two different PCR-based detection assays. This data gives support for use of capillary blood, a material which can be obtained easier by less invasive methods, for PCR-based malaria diagnostics, independent of the platform.

Colorectal cancer (CRC) is the second most-commonly diagnosed cancer among Korean Americans after breast cancer, with incidence rates exceeding that of lung, prostate, and stomach cancers. However, CRC screening rates are lower among Korean Americans than the general U.S. population. To understand barriers to screening in this population, we conducted 11 focus groups with 51 Korean Americans ages 40+ in the Washington, DC, metropolitan area between 2011 and 2016. Our analysis used the Health Belief Model as a framework. Motivators to seek screening include a family or personal history of cancer or gastrointestinal disease (high perceived susceptibility), knowing people with CRC (high severity), favorable test results reducing worry (high benefits), and physician recommendations (cues to action). Barriers to screening include the common misperception that Korean lifestyles prevent CRC (low susceptibility), the belief that cancer is normal for older adults (low severity), the assumption that screening only benefits symptomatic people (low benefits), the costs and potential risks of testing along with a preference for traditional Korean approaches to wellness (high barriers), and lack of health insurance (low self-efficacy). Interventions seeking to increase the rate of cancer screening in the Korean American community will benefit from emphasizing the burden from CRC among Korean Americans (increasing perceived susceptibility to CRC), explaining that colonoscopies can prevent CRC rather than just diagnosing it (increasing perceived benefits of screening), reducing anxieties about test procedures and embarrassment (reducing perceived barriers to screening), and improving clinical communication (improving cues to action and self-efficacy).

During the 2019-2020 academic year, 37 (17%) of 223 Council on Education for Public Health (CEPH) accredited or applicant schools and programs of public health offered Master of Public Health (MPH) degrees with concentrations in general global health. Concentration-specific competencies build on the foundational competencies required for all MPH students enrolled in CEPH-accredited programs. The most popular global health competencies focus on agencies and organizations, ethics and human rights, program management, social and environmental determinants of health, the global burden of disease, collaboration and partnerships, and cultural competency. There is significant overlap between the current concentration competencies and the ones recommended by the Association of Schools and Programs of Public Health in 2018. The online program descriptions for MPH concentrations in global health feature four key themes: globalization, low-income countries, social justice and equity, and culture and diversity. (1) Most programs emphasize transnational health issues and the effects of globalization on health in countries of all income levels. (2) Some programs have a special focus on preparation for serving low-income countries and other disadvantaged populations, such as refugees. (3) Most programs emphasize the social justice and equity issues underlying local and global health disparities. (4) Most programs promote development of the cultural knowledge, awareness, and skills required for serving diverse populations effectively as rising leaders in the international, national, or local public health workforce. Global health MPH programs prepare students for public health practice in resource-limited settings in their home communities as well as internationally.

INTRODUCTION: The World Health Organization recommends vaccination against hepatitis A virus (HAV) for children aged 1 year and older in areas where endemicity has shifted from high to intermediate. There are no recent comprehensive reviews of the epidemiology of HAV infection in Latin America, but seroprevalence and socioeconomic data suggest that, with improved clean water and sanitation systems, countries are transitioning to intermediate endemicity. AREAS COVERED: We conducted a systematic literature review of the epidemiology of HAV infection in 25 countries in the Latin American region, which included gray literature. We compiled data on HAV incidence and prevalence, including the identification of epidemiological changes observed in countries that established pediatric HAV vaccination programs. EXPERT OPINION: We identified 59 relevant articles, including 34 peer-reviewed seroprevalence studies (12 recent studies from Brazil), three incidence studies, and six vaccine impact studies (three from Argentina). Based on the estimated age at midpoint of population immunity in each country, most have a high-intermediate, intermediate, or low-intermediate level of HAV endemicity, suggesting that national childhood immunization may be an appropriate disease prevention strategy. However, recent data were lacking for most countries. Improved data quality and continued epidemiological surveillance are required for this region.

Background: A growing number of institutions of higher education offer undergraduate educational programs in global health. Objective: To identify all undergraduate minors in global health being offered in the United States during the 2019-20 academic year, categorize the curricula being used by secondary programs of study, evaluate the content of required foundational courses, and examine the types of experiential learning opportunities that are offered. Methods: A working group of the Consortium of Universities for Global Health (CUGH) conducted a systematic review of the websites of all accredited 4-year colleges and universities, identifying 84 institutions offering general global health minors. Findings: A typical global health minor consists of one introduction to global health course, one epidemiology or health research methods course, several additional required or selective courses, and one applied learning experience. Within this general structure, five curricular models are currently being used for global health minors: (1) intensive minors composed of specialty global health courses, (2) global public health minors built on a core set of public health courses, (3) multidisciplinary minors requiring courses in the sciences and social sciences, (4) anthropology centric minors, and (5) flexible minors. Conclusions: CUGH recommends ten undergraduate student learning objectives in global health that encompass the history and functions of global health; globalization and health; social determinants of health; environmental health; health and human rights; comparative health systems; global health agencies and organizations; the global burden of disease; global health interventions; and interdisciplinary and interprofessional perspectives.

Many jurisdictions enacted stay-at-home orders (also called shelter-in-place orders, safer-at-home orders, or lockdowns) when SARS-CoV-2 began spreading in the United States. Based on Google mobility data, every state had substantially fewer visits to transit stations, retail and recreation facilities, workplaces, grocery stores, and pharmacies by the end of March 2020 than in the previous two months. The mean decrease in visitation rates across destination categories was about 30 percent in states without stay-at-home orders and 40 percent in states with stay-at-home orders. Similarly, there were fewer routing requests received by Apple in large cities for public transportation, walking, and driving, with a 10 percentage point greater mean reduction in metropolitan areas under statewide stay-at-home orders. The pandemic led to large decreases in mobility even in states without legal restrictions on travel, but statewide orders were effective public health policy tools for reducing human movement below the level achieved through voluntary behavior change.
RESUMO
Background: There has been rapid growth in the popularity of undergraduate degrees in global and public health, but that growth has not been evenly distributed across different types of institutions of higher education. Objective: To examine the prevalence of undergraduate global and public health majors and minors and related degrees at a diversity of higher education institutions in the United States during the 2019-20 academic year. Methods: We examined curricular offerings at the top 100 national universities, national liberal arts colleges, regional universities, and regional colleges included in the 2020 U.S. News and World Report rankings. With ties, the dataset included 411 of the 1600 ranked U.S. colleges and universities. Findings: In total, 101 (25%) of the 411 schools offer a general public health, community health, or global health major, 105 (26%) a minor, and 144 (35%) a major and/or minor. When subdisciplines and other population health related programs are included, 160 (39%) offer a major, 183 (45%) a minor, and 227 (55%) a major and/or minor, including 83% of national universities, 57% of regional universities, 45% of national liberal arts colleges, and 35% of regional colleges. Global health programs, usually minors, are offered by 32% of national universities and 8% of national liberal arts colleges. Conclusions: Global and public health have become common areas of primary and secondary study at the bachelor's level at diverse schools in the United States. Although these degree pathways are especially prevalent at large urban universities, schools of all sizes, types, and locations have invested in offering educational programs in population health areas.

BACKGROUND: Loneliness is a common health problem among the elderly but is not well understood in the adolescent population, especially in low- and middle-income countries (LMICs). Adolescent loneliness can have adverse impacts on short- and long-term health status. METHODS: This study examined rates of self-reported loneliness and friendlessness among 76,982 secondary school students in 25 LMICs in Latin America and the Caribbean who participated in the Global School-based Student Health Survey (GSHS). After calculating the rates of reported loneliness and lack of close friends separately for nationally representative samples of boys and girls from each country, we used meta-analysis to pool results for prevalence rates and associations across all 25 countries and territories. RESULTS: About 1 in 6 students (18.1% [95% CI: 16.4%, 20.0%]) reported being lonely most or all of the time and/or having no close friends, including 19.9% of girls and 16.2% of boys. Girls were more likely than boys to report being lonely most or all of the time (14.6% vs. 9.2%, p < .05), but boys were more likely than girls to report that they had zero close friends (8.7% vs. 7.2%, p < .05). However, the majority of students who reported being lonely did not report having no close friends, and the majority of students who reported having no close friends did not report being lonely most or all of the time. CONCLUSIONS: Asking adolescents about both loneliness and friendships may capture the burden of social isolation among males and females better than a single question about loneliness. Successful interventions for reducing social isolation must be rooted in communities and integrated into comprehensive school and community health plans.

BACKGROUND: Malaria continues to affect over 200 million individuals every year, especially children in Africa. Rapid and sensitive detection and identification of Plasmodium parasites is crucial for treating patients and monitoring of control efforts. Compared to traditional diagnostic methods such as microscopy and rapid diagnostic tests (RDTs), DNA based methods, such as polymerase chain reaction (PCR) offer significantly higher sensitivity, definitive discrimination of Plasmodium species, and detection of mixed infections. While PCR is not currently optimized for routine diagnostics, its role in epidemiological studies is increasing as the world moves closer toward regional and eventually global malaria elimination. This study demonstrates the field use of a novel, ambient temperature-stabilized, multiplexed PCR assay in a small hospital setting in Sierra Leone. METHODS: Blood samples from 534 febrile individuals reporting to a hospital in Bo, Sierra Leone, were tested using three methods: a commercial RDT, microscopy, and a Multiplex Malaria Sample Ready (MMSR) PCR designed to detect a universal malaria marker and species-specific markers for Plasmodium falciparum and Plasmodium vivax. A separate PCR assay was used to identify species of Plasmodium in samples in which MMSR detected malaria, but was unable to identify the species. RESULTS: MMSR detected the presence of any malaria marker in 50.2% of all tested samples with P. falciparum identified in 48.7% of the samples. Plasmodium vivax was not detected. Testing of MMSR P. falciparum-negative/universal malaria-positive specimens with a panel of species-specific PCRs revealed the presence of Plasmodium malariae (n = 2) and Plasmodium ovale (n = 2). The commercial RDT detected P. falciparum in 24.6% of all samples while microscopy was able to detect malaria in 12.8% of tested specimens. CONCLUSIONS: Wider application of PCR for detection of malaria parasites may help to fill gaps existing as a result of use of microscopy and RDTs. Due to its high sensitivity and specificity, species coverage, room temperature stability and relative low complexity, the MMSR assay may be useful for detection of malaria and epidemiological studies especially in low-resource settings.
