ABSTRACT
Increased exposure to extreme heat from both climate change and the urban heat island effect-total urban warming-threatens the sustainability of rapidly growing urban settlements worldwide. Extreme heat exposure is highly unequal and severely impacts the urban poor. While previous studies have quantified global exposure to extreme heat, the lack of a globally accurate, fine-resolution temporal analysis of urban exposure crucially limits our ability to deploy adaptations. Here, we estimate daily urban population exposure to extreme heat for 13,115 urban settlements from 1983 to 2016. We harmonize global, fine-resolution (0.05°), daily temperature maxima and relative humidity estimates with geolocated and longitudinal global urban population data. We measure the average annual rate of increase in exposure (person-days/year-1) at the global, regional, national, and municipality levels, separating the contribution to exposure trajectories from urban population growth versus total urban warming. Using a daily maximum wet bulb globe temperature threshold of 30 °C, global exposure increased nearly 200% from 1983 to 2016. Total urban warming elevated the annual increase in exposure by 52% compared to urban population growth alone. Exposure trajectories increased for 46% of urban settlements, which together in 2016 comprised 23% of the planet's population (1.7 billion people). However, how total urban warming and population growth drove exposure trajectories is spatially heterogeneous. This study reinforces the importance of employing multiple extreme heat exposure metrics to identify local patterns and compare exposure trends across geographies. Our results suggest that previous research underestimates extreme heat exposure, highlighting the urgency for targeted adaptations and early warning systems to reduce harm from urban extreme heat exposure.

AIMS: Motile Aeromonas septicaemia (MAS) caused by motile Aeromonas species is an important disease in farmed freshwater fish due to intensification of culture and improper farm practices. This study characterized and profiled motile Aeromonas species recovered from clinically sick tilapia farmed in the Philippines, with a view to identifying targeted disease prevention and control measures against MAS in farmed tilapia species. METHODS AND RESULTS: Sixteen isolates from diseased farmed Nile tilapia were identified as Aeromonas veronii (n = 14), Aeromonas caviae (n = 1), and Aeromonas dhakensis (n = 1). Five biochemical profiles using API 20E were exhibited by the A. veronii strains giving an unreliable identification. A high level of agreement was observed in identifying the Aeromonas strains using 16S rRNA and rpoD gene sequencing, although the latter has a higher discriminatory value. Three or more virulence genes dominated by cytotoxic enterotoxin act and aerolysin aer were detected. Different genotypes based on virulence gene clustering suggested varied mechanisms used by Aeromonas to colonize and infect or to mutualistically co-exist with the fish. Acquired multiple antibiotic resistance was found in a single A. veronii isolate. All were susceptible to enrofloxacin, oxolinic acid, florfenicol, and chloramphenicol. Tetracycline and sulfonamide resistances and class 1 integron were detected in three A. veronii isolates. CONCLUSION: Several strains of motile aeromonads, especially A. veronii, which have varied genotypes based on virulence, biochemical profile, and antibiotic resistance, are involved in MAS in natural disease outbreaks in farmed Nile tilapia in the Philippines.

Agricultural production and household food security are hypothesized to play a critical role connecting climate change to downstream effects on women's health, especially in communities dependent on rainfed agriculture. Seasonal variability in agriculture strains food and income resources and makes it a challenging time for households to manage a pregnancy or afford a new child. Yet, there are few direct assessments of the role locally varying agricultural quality plays on women's health, especially reproductive health. In this paper we build on and integrate ideas from past studies focused on climate change and growing season quality in low-income countries with those on reproductive health to examine how variation in local seasonal agricultural quality relates to childbearing goals and family planning use in three countries in sub-Saharan Africa: Burkina Faso, Kenya, and Uganda. We use rich, spatially referenced data from the Performance Monitoring for Action (PMA) individual surveys with detailed information on childbearing preferences and family planning decisions. Building on recent advances in remote monitoring of seasonal agriculture, we construct multiple vegetation measures capturing different dimensions of growing season conditions across varying time frames. Results for the Kenya sample indicate that if the recent growing season is better a woman is more likely to want a child in the future. In Uganda, when the growing season conditions are better, women prefer to shorten the time until their next birth and are also more likely to discontinue using family planning. Additional analyses reveal the importance of education and birth spacing in moderating these findings. Overall, our findings suggest that, in some settings, women strategically respond to growing season conditions by adjusting fertility aspirations or family planning use. This study also highlights the importance of operationalizing agriculture in nuanced ways that align with women's lives to better understand how women are impacted by and respond to seasonal climate conditions.
ABSTRACT
The goal of this article is to consider data solutions to investigate the differential pathways that connect climate/weather variability to child health outcomes. We apply several measures capturing different aspects of climate/weather variability to different time periods of in utero exposure. The measures are designed to capture the complexities of climate-related risks and isolate their impacts based on the timing and duration of exposure. Specifically, we focus on infant birth weight in Mali and consider local weather and environmental conditions associated with the three most frequently posited potential drivers of adverse health outcomes: disease (malaria), heat stress, and food insecurity. We focus this study on Mali, where seasonal trends facilitate the use of measures specifically designed to capture distinct aspects of climate/weather conditions relevant to the potential drivers. Results indicate that attention to the timing of exposures and employing measures designed to capture nuances in each of the drivers provides important insight into climate and birth weight outcomes, especially in the case of factors impacted by precipitation. Results also indicate that high temperatures and low levels of agricultural production are consistently associated with lower birth weights, and exposure to malarious conditions may increase likelihood of nonlive birth outcomes.

OBJECTIVE: We analyze fertility preferences among women at risk of pregnancy with children ages five or younger as a function of two food security metrics: perceptions of household hunger and child stunting (height for age z scores ≤ -2.0) in order to convey a robust picture of food insecurity. METHODS: We use data from the 2016 Tanzania Demographic and Health Surveys to analyze this research question. Multinomial generalized logit models with cluster-adjusted standard errors are used to determine the association between different dimensions of food insecurity and individual-level fertility preferences. RESULTS: On average, women who experience household hunger are 19% less likely to want more children compared to women who do not experience household hunger (AOR: 0.81, p = 0.02) when controlling for education, residence, maternal age, number of living children, and survey month. Adjusting for the same covariates, having at least one child ≤ 5 years old who is stunted is associated with 13% reduced odds of wanting more children compared to having no children stunted (AOR: 0.87, p = 0.06). CONCLUSIONS FOR PRACTICE: In the context of a divided literature base, this research aligns with the previous work identifying a preference among women to delay or avoid pregnancy during times of food insecurity. The similarity in magnitude and direction of the association between food insecurity and fertility preferences across the two measures of food insecurity suggest a potential association between lived or perceived resource insecurity and fertility aspirations. Further research is needed in order to establish a mechanism through which food insecurity affects fertility preferences. SIGNIFICANCE STATEMENT: Individual fertility preferences are sensitive to dynamic multi-level factors in a woman's life. While qualitative research has explored the effect that food insecurity and associated resource constraints have on fertility preferences, results are conflicting. Here, we quantitatively examine how individual woman's fertility preferences associate with two measures of food insecurity and qualitatively compare the associations across food insecurity measures. We establish that two food insecurity measures- household hunger and child stunting- capture similar populations and have similar associations with fertility preferences. This is a critical step forward in understanding the dynamic relationship between resource availability, child well-being, and fertility preferences.

We examine the relationships between climatic conditions, breastfeeding behavior, and maternal time use in Ethiopia. Infant feeding practices are important predictors of child nutrition that may be affected by a number of factors including mother's time engaging in agricultural labor, food security, cultural beliefs, and antenatal care. We use panel data from the Living Standards Measurement Study to investigate linkages between climatic conditions during a child's first year of life and year prior to birth and duration of exclusive breastfeeding. We then explore one potential mechanism: women's agricultural labor. Results indicate that rainfall during the primary agricultural season-kiremt-in a child's first year of life plays an important role in duration of exclusive breastfeeding. Experiencing 25 cm of average monthly kiremt rainfall, versus 5 cm, is associated with a 20-percentage-point decrease in the likelihood of being exclusively breastfed for the recommended six months. More kiremt rainfall is associated with a greater number of days that women spend planting and harvesting, and at high levels of rainfall women with infants do not engage in significantly fewer days of agricultural labor than those without infants. Lastly, we find that during the year before birth, greater rainfall during kiremt as well as the dry season is associated with a lower likelihood of six months of exclusive breastfeeding, potentially due to the early introduction of complementary foods. Our findings indicate that agricultural labor demands may in part drive breastfeeding behaviors, leading to "sub-optimal" feeding practices in the short-term, but resulting in improved household food security in the longer-term.
ABSTRACT
OBJECTIVES: To examine an association between climate variability and birth weight in Mali and Kenya in relation to the local agricultural specialization. METHODS: We combined health and sociodemographic data from the Demographic Health Surveys for Kenya (2008 and 2014) and Mali (2006 and 2012) with detailed data on precipitation, temperature, and vegetation. We analyzed the association between climate variability and birth weight by using multilevel regression models for the most common agricultural specializations: food cropping, cash cropping, and pastoralism. RESULTS: There are differences in sensitivity to climate among different agricultural communities. An additional 100 millimeters of rainfall during the 12-month period before birth was associated with a 47-gram (P = .001) and 89-gram (P = .10) increase in birth weight for food croppers in Kenya and Mali, respectively. Every additional hot month in food-cropping communities in Kenya was associated with a 71-gram decrease in birth weight (P = .030), likely because of food croppers' limited use of modern agricultural techniques. Overall, cash croppers are least sensitive to climate variability in both countries. CONCLUSIONS: Effective climate change adaptation strategies are essential for protecting and improving health outcomes and should be tailored to local households' livelihood strategies.

Poor women who live in peri-urban communities are often faced with food insecurity due to seasonal variations in food availability and accessibility. Additionally, in these communities, fertility levels are often elevated despite geographic proximity to urban areas with low cost contraception. We conducted five focus group interviews to investigate the lived experiences of childbearing in peri-urban Ouagadougou, Burkina Faso to understand the behavioral and biological determinants of fertility outcomes. In the analysis of the interviews we pay particular attention to seasonal food insecurity experiences and the biological and behavioral determinants of childbearing. Our results suggest that there are less optimal times of year for childbearing and that poor, peri-urban women adjust their behavior accordingly. The results also suggest that there remain important barriers to contraceptive use even in cases where individuals associate pregnancy and childbearing with physical and psychological risk. This paper provides greater depth in understanding the determinants of fertility in resource-poor, peri-urban communities and points to some barriers for lowering fertility in similar areas.
ABSTRACT
In some contemporary populations, fertility levels appear to plateau, with women maintaining a consistently high level of fertility for a relatively extended period. Because this plateau does not reflect the historical patterns observed in Europe, the focus of most studies on fertility patterns, mechanisms underlying the plateau and the reinstatement of a decline have not been fully explored and are not fully understood. Through the construction of fertility histories of 25,000 women using multiple years of health survey data, we analyze some of the components of stalled fertility as they pertain to Guatemala, the only Central American country to have experienced a stalled fertility decline.

Climate change and degradation of ecosystem services functioning may threaten the ability of current agricultural systems to keep up with demand for adequate and inexpensive food and for clean water, waste disposal and other broader ecosystem services. Human health is likely to be affected by changes occurring across multiple geographic and time scales. Impacts range from increasing transmissibility and the range of vectorborne diseases, such as malaria and yellow fever, to undermining nutrition through deleterious impacts on food production and concomitant increases in food prices. This paper uses case studies to describe methods that make use of satellite remote sensing and Demographic and Health Survey data to better understand individual-level human health and nutrition outcomes. By bringing these diverse datasets together, the connection between environmental change and human health outcomes can be described through new research and analysis.
ABSTRACT
Niger is highly vulnerable to rainfall variability, often with adverse socioeconomic consequences. This study examined observed subseasonal rainfall variability during Niger's monsoon season (May to September). Using k-means clustering of dekadal (ten-day) rainfall, a typology was developed for the annual evolution of the monsoon season. Year-to-year rainfall variability for each of the first few dekads of the season is modest, but the middle, or peak of the rainy season demonstrates large interannual variability. Clustering analysis of annual timeseries for each dekad of the season revealed two types of monsoon progression. The distinction between the two types is strongly dependent on differences during the latter half of the season. For the first and third ten-day periods in August, and the first ten days in September, the two groups of years are more distinct. These results imply that while reliable prediction of the timing of anomalous onsets will be challenging, due to the relatively narrow range of uncertainty historically, there are opportunities for further exploration of dynamic and or statistical predictors or precursors using this typology that could potentially provide better information for decision-makers, especially with respect to agriculture.

BACKGROUND: Internal migration is an important part of the transition to adulthood for many young people in sub-Saharan Africa. This study examines how migration, in relation to marriage and parenthood, impacts modern contraceptive use and health facility visits amongst young urban women. METHODS: We draw on Performance Monitoring for Action (PMA) surveys conducted in Burkina Faso, Côte d'Ivoire, Democratic Republic of Congo, Kenya, Nigeria, and Uganda (2019-2022). Our analysis is unique in being able to adjust for whether women wanted to get pregnant soon. Our sample includes women ages 15-24 years currently residing in urban areas (n = 6,225). We conducted logistic regression models clustered by village level identifier to explore the sequence of life events and the timing of migration in relation to current modern contraceptive use and recent health facility visit, a proxy for engagement with formal health services. RESULTS: The timing of migration matters more than the sequence of these life events. Young urban women who experienced both migration and a birth, regardless of the order, had increased contraceptive use and recent health facility visit, compared to women who had only experienced one event or neither. Young women who migrated in the past year had 24% lower odds of using a modern method (Odds Ratio = 0.76; 95% confidence interval 0.63, 0.91), adjusting for demographic factors and adjusting for fertility preference (Wanting to get pregnant soon). Having had a birth was highly significant for health facility visit and among women who had had a birth, those who migrated in the last year had lower odds of a recent visit (OR = 0.68, 95% CI 0.41, 0.89). Results suggest an initially disruptive effect of migration. DISCUSSION: Our results suggest young women who recently migrated to urban areas may need additional support in accessing contraception and formal health services for themselves or their children.

OBJECTIVE: The introduction of peer support in mental health teams creates opportunities and challenges for both peer and non-peer staff. However, the majority of research on mental health workers' (MHWs) experiences with peer support comes from high-income countries. Using Peer Support In Developing Empowering Mental Health Services (UPSIDES) is an international multicentre study, which aims at scaling up peer support for people with severe mental illness in Europe, Asia and Africa. This study investigates MHWs experiences with UPSIDES peer support. DESIGN: Six focus groups with MHWs were conducted approximately 18 months after the implementation of the UPSIDES peer support intervention. Transcripts were analysed with a descriptive approach using thematic content analysis. SETTING: Qualitative data were collected in Ulm and Hamburg (Germany), Butabika (Uganda), Dar es Salaam (Tanzania), Be'er Sheva (Israel) and Pune (India). PARTICIPANTS: 25 MHWs (19 females and 6 males) from UPSIDES study sites in the UPSIDES Trial (ISRCTN26008944) participated. FINDINGS: Five overarching themes were identified in MHWs' discussions: MHWs valued peer support workers (PSWs) for sharing their lived experiences with service users (theme 1), gained trust in peer support over time (theme 2) and provided support to them (theme 3). Participants from lower-resource study sites reported additional benefits, including reduced workload. PSWs extending their roles beyond what MHWs perceived as appropriate was described as a challenge (theme 4). Perceptions about PSWs varied based on previous peer support experience, ranging from considering PSWs as equal team members to viewing them as service users (theme 5). CONCLUSIONS: Considering local context is essential in order to understand MHWs' views on the cooperation with PSWs. Especially in settings with less prior experience of peer support, implementers should make extra effort to promote interaction between MHWs and PSWs. In order to better understand the determinants of successful implementation of peer support in diverse settings, further research should investigate the impact of contextual factors (eg, resource availability and cultural values).

This study examines how trust was associated with social distancing during the early days of the COVID-19 pandemic in Burkina Faso and Kenya. It fills gaps in previous research on trust and health by 1) simultaneously considering the relationship of individual- and aggregate-level indicators of trust, and 2) evaluating trust in local government and national government separately. Performance Monitoring for Action (PMA) data on COVID-precautionary measures and individual-level trust measures were spatially linked with aggregated trust data from the Afrobarometer to create a multilevel dataset. PMA data show that women in Kenya were generally more likely to report taking COVID-precautionary measures relative to Burkinabé women, although levels of these measures were high in both countries. Hierarchical logistic models for each country show levels of interpersonal trust mattered more in Burkina Faso. Although the association between individual-level trust in government and social distancing was not statistically significant, overall levels of trust in the region where an individual lived were associated with social distancing. We found a significant interaction effect between regional trust in the national government and regional trust in local government: individuals in regions where trust was high in both national and local government were the most likely to socially distance; individuals in regions with low local government trust but high national government trust were less likely to report social distancing. We unpack possible implications of these findings; they point to the importance of a unified government front within African countries in promoting health safety measures during a pandemic.
ABSTRACT
The Trump administration reinstated and expanded the Mexico City Policy (MCP) in 2017 as the Protecting Life in Global Health Assistance (PLGHA) policy, forbidding international organizations receiving all U.S. health assistance from promoting abortion. Existing evidence suggests that abortion rates rise under the MCP, but the direct effect of U.S. funding restrictions on supply and use of family planning has received less attention. By studying PLGHA's impact on health service delivery providers and women in eight sub-Saharan African countries, we are able to fill this gap. We find that health facilities provide fewer family planning services, including emergency contraception, and that women are less likely to use contraception and more likely to have given birth recently under the policy. These findings suggest that PLGHA has important unintended consequences that are detrimental to reproductive health and the autonomous decision-making of health service providers and women.

OBJECTIVES: Despite the established evidence base for mental health peer support work, widespread implementation remains a challenge. This study aimed to explore societal and organisational influences on the implementation of peer support work in low-income and high-income settings. DESIGN: Study sites conducted two focus groups in local languages at each site, using a topic guide based on a conceptual framework describing eight peer support worker (PSW) principles and five implementation issues. Transcripts were translated into English and an inductive thematic analysis was conducted to characterise implementation influences. SETTING: The study took place in two tertiary and three secondary mental healthcare sites as part of the Using Peer Support in Developing Empowering Mental Health Services (UPSIDES) study, comprising three high-income sites (Hamburg and Ulm, Germany; Be'er Sheva, Israel) and two low-income sites (Dar es Salaam, Tanzania; Kampala, Uganda) chosen for diversity both in region and in experience of peer support work. PARTICIPANTS: 12 focus groups were conducted (including a total of 86 participants), across sites in Ulm (n=2), Hamburg (n=2), Dar es Salaam (n=2), Be'er Sheva (n=2) and Kampala (n=4). Three individual interviews were also done in Kampala. All participants met the inclusion criteria: aged over 18 years; actual or potential PSW or mental health clinician or hospital/community manager or regional/national policy-maker; and able to give informed consent. RESULTS: Six themes relating to implementation influences were identified: community and staff attitudes, resource availability, organisational culture, role definition, training and support and peer support network. CONCLUSIONS: This is the first multicountry study to explore societal attitudes and organisational culture influences on the implementation of peer support. Addressing community-level discrimination and developing a recovery orientation in mental health systems can contribute to effective implementation of peer support work. The relationship between societal stigma about mental health and resource allocation decisions warrants future investigation. TRIAL REGISTRATION NUMBER: ISRCTN26008944.

Acute malnutrition affects a sizeable number of young children around the world, with serious repercussions for mortality and morbidity. Among the top priorities in addressing this problem are to anticipate which children tend to be susceptible and where and when crises of high prevalence rates would be likely to arise. In this article, we highlight the potential role of conflict and climate conditions as risk factors for acute malnutrition, while also assessing other vulnerabilities at the individual- and household-levels. Existing research reflects these features selectively, whereas we incorporate all the features into the same study. The empirical analysis relies on integration of health, conflict, and environmental data at multiple scales of observation to focuses on how local conflict and climate factors relate to an individual child's health. The centerpiece of the analysis is data from the Demographic and Health Surveys conducted in several different cross-sectional waves covering 2003-2016 in Kenya, Nigeria, and Uganda. The results obtained from multi-level statistical models indicate that in Kenya and Nigeria, conflict is associated with lower weight-for-height scores among children, even after accounting for individual-level and climate factors. In Nigeria and Kenya, conflict lagged 1-3 months and occurring within the growing season tends to reduce WHZ scores. In Uganda, however, weight-for-height scores are primarily associated with individual-level and household-level conditions and demonstrate little association with conflict or climate factors. The findings are valuable to guide humanitarian policymakers and practitioners in effective and efficient targeting of attention, interventions, and resources that lessen burdens of acute malnutrition in countries prone to conflict and climate shocks.
ABSTRACT
Higher perceived social support has been shown to buffer the impact of negative stressful events like childhood abuse on health outcomes. Yet, the role of perceived social support as a mediator of the association between childhood abuse and pain-related characteristics is not well understood. The present study explored this premise. Patients (n = 1,542) presenting to a tertiary-care, outpatient pain clinic completed a cross-sectional survey consisting of regularly collected clinical data and validated measures. Path analysis suggested that the impact of childhood abuse on sensory and affective pain-related characteristics was partially explained by perceived emotional support. Survivors of childhood abuse display a more complex clinical pain phenotype and this extends to more negative perceptions of social support. Our findings may reflect processes whereby childhood abuse negatively impacts social relationships across the lifespan, and these negative social perceptions and relationships influence sensory and affective components of pain.
ABSTRACT
Community-based mental health initiatives are uniquely positioned to understand the mental health needs of their local population and provide relevant, culturally appropriate and sustainable responses. However, at the grassroots level, mental health initiatives in low- and middle-income countries face key challenges, such as inadequate funding, barriers to demonstrating impact and difficulty engaging with stakeholders. The Ember Mental Health programme establishes 12-month partnerships with community-based mental health initiatives in low- and middle-income countries to support them to address these challenges, grow and achieve sustainability. This paper outlines a longitudinal qualitative study conducted to evaluate the 2020-2021 Ember Mental Health programme. Data were collected from March 2020 to March 2021 through semistructured interviews conducted with 11 initiatives at various time points throughout their Ember Mental Health partnership. A framework approach was used to analyse all data in its original language. Findings indicated that initiatives particularly benefited from provision of side-by-side mentorship; opportunities for skills strengthening and strategic thinking; occasions to network with other like-minded initiatives and/or experts in global mental health; and support on team empowerment and well-being. Based on these findings, we put forward various recommendations for funders and other stakeholders working to support community-based mental health initiatives in low- and middle-income countries. Through establishing collaborative partnerships that challenge more top-down, traditional funder-grantee relationships, it is possible to support the rich ecosystem of initiatives working to address the mental health needs of communities.

OBJECTIVES: Current translation guidelines do not include sufficiently flexible translation approaches for different study materials. We aimed to develop a proportionate methodology to inform translation of all types of study materials in global health trials. DESIGN: The design included three stages: (1) categorisation of study materials, (2) integration of existing translation frameworks and (3) methodology implementation (Germany, India, Israel, Tanzania and Uganda) and refinement. PARTICIPANTS: The study population comprised 27 mental health service users and 27 mental health workers who were fluent in the local language in stage 7 (pretesting), and 54 bilingual mental health service users, aged 18 years or over, and able to give consent as judged by a clinician for step 9 (psychometric evaluation). SETTING: The study took place in preparation for the Using Peer Support in Developing Empowering Mental Health Services (UPSIDES) randomised controlled trial (ISRCTN26008944). PRIMARY OUTCOME MEASURE: The primary outcome measure was the Social Inclusion Scale (SIS). RESULTS: The typology identifies four categories of study materials: local text, study-generated text, secondary measures and primary measure. The UPSIDES Proportionate Translation Methodology comprises ten steps: preparation, forward translation, reconciliation, back translation, review, harmonisation, pretesting, finalisation, psychometric evaluation and dissemination. The translated primary outcome measure for the UPSIDES Trial (SIS) demonstrated adequate content validity (49.3 vs 48.5, p=0.08), convergent validity and internal consistency (0.73), with minimal floor/ceiling effects. CONCLUSION: This methodology can be recommended for translating, cross-culturally adapting and validating all study materials, including standardised measures, in future multisite global trials. The methodology is particularly applicable to multi-national studies involving sites with differing resource levels. The robustness of the psychometric findings is limited by the sample sizes for each site. However, making this limitation explicit is preferable to the typical practice of not reporting adequate details about measure translation and validation. TRAIL REGISTRATION NUMBER: ISRCTN26008944.
