This study quantifies excess deaths associated with heat waves in Hong Kong from 2014 to 2023. Methods Daily age- and sex-specific mortality rates and population data were obtained from the Hong Kong Life Tables and Census and Statistics Department. Temperature data came from the Hong Kong Observatory, and...

BackgroundHelmet use is a proven safety measure that reduces the risk of head injury among cyclists and e-scooter riders. Despite legal requirements for pedal bikes and e-bikes in Australia, compliance varies, particularly among users of electric vehicles. The growing popularity of e-bikes and e-scooters in urban areas presents new public health challenges, yet observational data on helmet use, behavioural determinants, and the effectiveness of safety interventions remain limited. AimPhase 3 of...

Objective: Posttraumatic stress disorder (PTSD) after a traumatic birth is a serious but overlooked maternal morbidity, affecting ~20% of women following medically complicated deliveries. PTSD can undermine maternal caregiving. Rapid screening tools suited to busy obstetric settings are lacking. We developed and evaluated a brief screener, derived from the 20-item PTSD Checklist for DSM-5 (PCL-5), to identify PTSD related to childbirth. Study Design: We enrolled 107 women with traumatic childbir...

Background: Out-of-hospital cardiac arrest (OHCA) survival depends on timely bystander cardiopulmonary resuscitation (CPR) and quick defibrillation via automated external defibrillator (AED). However, access to CPR education and willingness to intervene are not equitably distributed. Within the Muslim community, intersecting religious identity, language, immigration-related concerns, and other social determinants of health may affect CPR/AED education, bystander response, and ultimately OHCA out...

Background. Although health mediation is widely studied in the U.S. through community health worker programs, evidence on their effectiveness in promoting cancer screening in Europe is limited. Since 2022, the "13 en Sante" program has implemented a multicomponent health mediation intervention -combining educational activities, outreach strategies, and navigation support- in socioeconomically disadvantaged neighbourhoods of Marseille, France. This study evaluates the effectiveness of this progra...

Background: Type 2 diabetes is a growing challenge in low- and middle-income countries, where health systems face major capacity gaps. Participatory learning and action (PLA) has shown effectiveness in preventing type 2 diabetes in Bangladesh, but little is known about its use in other LMICs for diabetes. The EMPOWER-D (Engagement of community through Participatory learning and action for cOntrol and prevention of type 2 diabetes) trial is testing PLA for diabetes prevention in communities in Pa...

Background: In low- and middle-income countries, the burden of hypertension is increasing. Medication adherence is a critical component of reducing hypertension-related cardiovascular disease (CVD) risk and death. There are many barriers to hypertension medication adherence, including challenges with access to and possession of medication. To address these challenges, we aim to implement a strategy in rural western Kenya that combines peer delivery of medications and health information technolog...

BackgroundZero-dose children, defined as those who have not received a first dose of a diphtheria-pertussis-tetanus (DPT)-containing vaccine, represent one of the sharpest manifestations of inequity in immunisation systems. Nigeria remains one of the largest contributors to the global zero-dose burden, with North-East Nigeria facing intersecting crises of conflict, population displacement, governance fragility, and weakened primary health care. Existing research has largely focused on structural...

Wastewater-based epidemiology (WBE) is an effective surveillance approach for monitoring viruses of public health relevance at the community level, complementing clinical surveillance systems. Molecular methods such as PCR/qPCR are widely used for targeted detection, while next-generation sequencing (NGS) with targeted enrichment panels has emerged as a complementary strategy for broader viral detection and genomic characterization. This study comparatively evaluated conventional PCR/qPCR and a ...

BackgroundText messages are a low-cost digital health solution that can provide information directly to mothers. We aimed to evaluate a text message program, called Essential Coaching for Every Mother Tanzania (ECEM-TZ), designed to improve maternal access to essential newborn care education during the immediate 6-week postnatal period. MethodsA randomized controlled trial was conducted in Dar es Salaam, Tanzania. ECEM-TZ consists of standardized text messages from birth to 6 weeks postpartum t...

Students who frequently miss school are at greater risk for academic difficulty. High levels of absenteeism as early as kindergarten have been associated with long-term consequences, such as low reading proficiency in Grade 3 and low academic achievement in Grade 5, both of which have been associated with lower rates of high school graduation and enrollment in post-secondary education. The prevalence of school absenteeism has increased significantly since the COVID-19 pandemic and there have bee...

Nocturnal glucose regulation is modulated by autonomic and circadian mechanisms, yet their dynamic interplay in apparently healthy, free-living populations remains poorly studied. Here, we assessed 227,860 nights of concurrent sleep data from Ultrahuman AIR ring and M1 continuous glucose monitoring (CGM) system across 5849 adults globally to examine nocturnal cardio-metabolic coupling. We found that higher sleep consistency was inversely associated with glucose variability, and vice versa. Unsup...

BackgroundPostnatal care is crucial for assessing and improving the health of both mothers and newborns, yet its coverage remains low in Ethiopia. Timely, high-quality postnatal care, especially within the first week after birth, is essential to reduce maternal and neonatal mortality. Family-led postnatal care is an innovative model for reaching postnatal mothers and newborns during the first week after birth. Leveraging self-care principles, mothers, with the support from family and guided by a...

Despite the relevance of spatial mapping in analyzing the health situation and understanding the risk factors and determinants of leptospirosis, peripheral urban communities often remain invisible on maps, which tend to use data and methods that do not express community contribution nor promote local participation. Furthermore, in the implementation of sanitation interventions, the same happens: there is limited user participation, and a lack of identification of intervention needs based on the...

BackgroundPacked lunches are a common feature of early childhood food provision, yet evidence describing their nutritional composition in early years settings remains limited. Understanding the foods provided during this developmental period is important, given the potential influence of early dietary exposures on later health. AimTo characterise the composition, nutritional quality, cost, and dietary patterns of packed lunches brought from home in Early Childhood Education and Care settings, a...

BackgroundNewborns requiring inpatient care, particularly small and sick newborns (SSNBs), face high risk of mortality. Newborns referred from other facilities may experience worse outcomes than those born and managed within the same hospital (inborn newborns). Understanding factors contributing to this disparity in outcomes could support efforts to scale-up care and accelerate progress towards achieving Sustainable Development Goals target 3.2. MethodsData on 130,773 newborns admitted to 13 ho...
