Hypertension (HTN) is the primary cause of preventable cardiovascular-related deaths globally, representing the most important modifiable risk factor for preventing such deaths. Nearly 700 million of the 1.3 billion adults with HTN worldwide remain untreated, most of whom live in low-and middle-income countries, including East Africa. Barriers to the diagnosis of HTN also impact treatment adherence after diagnosis and the initiation of treatment. This scoping review used a qualitative synthesis method to describe studies examining the cultural and contextual factors influencing HTN treatment adherence in East Africa and the lived experiences of patients with HTN to gain a better understanding of these factors in the region. A total of 34 studies, 25 qualitative and 9 mixed-methods designs from five East African nations were included in the final review. Reported influencing factors are classified into individual, structural, and social factors. Lack of HTN literacy and limited risk perception were often cited as individual barriers to adherence, along with mental health challenges, including fear of stigma, while trust and HTN literacy enhanced adherence. Inconsistent healthcare delivery, lack of access, and financial constraints were the most reported structural factors. Social norms surrounding health behaviours and attitudes towards HTN treatment were identified as key determinants of adherence at the social level. The findings underscore the complex interplay of individual, structural, and social factors associated with HTN treatment adherence in East Africa, offering practical ways to enhance adherence in the region at all three levels.

Given the surging economic and health costs associated with childhood stunting, identifying its associated factors is crucial. This study therefore explores a key determinant of long-term nutritional status, women’s participation in household decision-making in the context of Pakistan. To empirically estimate this association, three-level modelling was employed by pooling the data from two recent nationally representative survey rounds PDHS 2012–13 and PDHS 2017–18. Multilevel analysis was better suited compared to traditional methods for robust estimates because of the hierarchical nature of the data. Women’s decision-making power was measured by formulating an index through factor analysis from the direct questions about women’s participation in household decisions. This study found a positive association between women’s decision-making power and children’s nutritional growth at the national level, with no significant changes across the survey years. However, this relationship was moderated by regional variations, which was more pronounced in Sindh and relatively modest in other regions. The sensitivity analysis showed that among the different decision-making domains, only women’s participation in large household purchases was significantly and positively associated with child linear growth. The insights of this research suggest that nutrition-oriented policies should also consider non-nutritional factors, like women’s decision-making power when designing projects for target population. Meanwhile, it is also crucial to recognize that decision-making power is a contextual factor and its effect on child nutritional growth may vary across regions.

Mortality trends among Indigenous peoples in Brazil remain poorly characterised. An ecological time-series study (2010–2022) was conducted, comparing Indigenous and non-Indigenous populations using nationwide open-access demographic and mortality data. Mortality was stratified by sex, age, and ICD-10 groups, populations were compared using Pearson’s chi-square test (p < 0.05), and trends were evaluated with joinpoint regression (JR) to estimate Average Annual Percentage Changes (AAPCs). Between 2010 and 2022, mortality among Indigenous peoples increased by 82.5% (from 2,927 to 5,343), compared with a 42.3% increase in the non-Indigenous population. Over 40% of deaths among Indigenous peoples occurred outside health facilities in both years, versus fewer than 30% among non-Indigenous populations. Crude mortality rates remained lower in Indigenous peoples (2010: 35.8 versus 55.9; 2022: 43.5 versus 74.8 per 10,000 population). However, age-specific differences were marked: mortality among Indigenous children and adolescents (0–19 years) was 3.3 times higher in 2010 and 3.8 times higher in 2022, while mortality among adults aged ≥40 years was approximately 2.5 times lower in both years compared with non-Indigenous populations (all p < 0.05). Mortality rates among Indigenous peoples were consistently higher for maternal, perinatal, and congenital conditions in both 2010 and 2022. JR revealed heterogeneous proportional mortality trends: significant increases in perinatal, congenital, and external causes (AAPC approximately 5.0–6.4%), as well as neoplasms, circulatory, haematological, digestive, respiratory, and endocrine/metabolic diseases (AAPC approximately 1.6–4.4%); a significant decline in infectious and parasitic diseases (AAPC −6.6%); and stability in other groups. Indigenous peoples in Brazil continued to face unfavourable mortality, particularly among children, adolescents, and maternal conditions. Many leading causes of death are preventable. Strengthening primary healthcare, expanding prenatal and perinatal services, improving vaccination and mental-health support, and adopting culturally safe, community-driven strategies to address chronic diseases are critical to reducing inequities and preventable deaths.

Loneliness and social isolation represent persisent global public health concerns, particurarly for people in later life, with extensive mental, social, and biological consequences. Both have been associated with increased risk of depression, anxiety, dementia, cardiovascular disease, premature mortality, and greater demand for health and social care services. A growing body of evidence indicates that nature-based interventions are effective in reducing loneliness, enhancing mood, and promoting overall well being, yet they still remain underutilised within health and social care strategies; particularly for older adults and those with limited mobility. One such initiative, Cycling Without Age, a grassroots programme, demonstrates the potential of nature-based interventions. Evidence across multiple contexts indicates improvements in mood, life satisfaction, and social connectedness, alongside benefits for families and care staff. Cycling Without Age illustrates a type of scalable, person-centred intervention that could be integrated into healthy ageing strategies. However, rigourous large-scale research remains scarce, which highlights the need for further evaluation to guide policy adoption and sustainable implementation. Effective responses to loneliness and social isolation require integrated support programmes that foster social connectedness and healthy ageing, delivered through coordinated efforts spanning public health, urban design, and community services.
