Background
Asthma remains highly prevalent, with more severe symptoms in low-income to middle-income countries (LMICs) compared with high-income countries. Identifying risk factors for severe asthma symptoms can assist with improving outcomes. We aimed to determine the prevalence, severity and ris...k factors for asthma in adolescents in an LMIC.
Methods
A cross-sectional survey using the Global Asthma Network written and video questionnaires was conducted in adolescents aged 13 and 14 from randomly selected schools in Durban, South Africa, between May 2019 and June 2021.
Results
A total of 3957 adolescents (51.9% female) were included. The prevalence of lifetime, current and severe asthma was 24.6%, 13.7% and 9.1%, respectively. Of those with current and severe asthma symptoms; 38.9% (n=211/543) and 40.7% (n=147/361) had doctor-diagnosed asthma; of these, 72.0% (n=152/211) and 70.7% (n=104/147), respectively, reported using inhaled medication in the last 12 months. Short-acting beta agonists (80.4%) were more commonly used than inhaled corticosteroids (13.7%). Severe asthma was associated with: fee-paying school quintile (adjusted OR (CI)): 1.78 (1.27 to 2.48), overweight (1.60 (1.15 to 2.22)), exposure to traffic pollution (1.42 (1.11 to 1.82)), tobacco smoking (2.06 (1.15 to 3.68)), rhinoconjunctivitis (3.62 (2.80 to 4.67)) and eczema (2.24 (1.59 to 3.14)), all p<0.01.
Conclusion
Asthma prevalence in this population (13.7%) is higher than the global average (10.4%). Although common, severe asthma symptoms are underdiagnosed and associated with atopy, environmental and lifestyle factors. Equitable access to affordable essential controller inhaled medicines addressing the disproportionate burden of asthma is needed in this setting.

The Social and Behaviour Change Communication (SBCC) Strategy for the Prevention of the Re-establishment of Malaria Transmission in Timor-Leste forms part of the National Strategic Plan (NSP) for 2021–2025. The strategy aims to support Timor-Leste's efforts to sustain malaria elimination by promot...ing responsive and preventive behaviours through targeted communication and community engagement. Created in collaboration with the Ministry of Health, the WHO, the Global Fund and other stakeholders, the SBCC strategy implements recommendations from the 2020 external review of the National Malaria Programme. Building on previous BCC initiatives (2015–2020), it emphasises surveillance, diagnosis, treatment and vector control, particularly focusing on vulnerable populations. The SBCC strategy provides partners and implementers with a dynamic guide to designing context-specific communication interventions that support malaria elimination and prevent the re-establishment of transmission.

South Africa reported it fist case of COVID-19 on 5 March 2020. While the first cases were imported, local transmission has led to a rapid increase in the number of cases. As of 21 April 2020, more than 3,400 cases and 58 deaths had been confirmed. On 15 March, President Cyril Ramaphosa declared a n...ational state of disaster, and the government has since taken several measures to curb the spread of the virus, including closing borders, implementing strict social distancing measures and a 35-day nation-wide lockdown. These measures, along with the global economic shock caused by the pandemic, are expected to generate rising needs requiring an immediate and urgent response. Although South Africa is considered an upper-middle-income country, the amount of disparities—social, economic, and gender—make the country particularly vulnerable during this emergency.

The article explores the underlying factors influencing unhealthy diets and sedentary lifestyles among adolescents in Kilifi County, Kenya. Using a qualitative approach, the study involved interviews and focus group discussions with adolescents, stakeholders, and young adults. Key findings include a... preference for unhealthy, carbohydrate-rich, and sugary foods over traditional and nutritious options, exacerbated by factors like low socioeconomic status, urbanization, and poor farming practices.
Sedentary behavior, such as gambling and extensive technology use, was prevalent, often replacing physical activity. Protective factors like school attendance, community-based services, and parental engagement were identified as mitigating risks. The study highlights the importance of ecological intervention strategies targeting intrapersonal, interpersonal, and community factors to address unhealthy behaviors and promote better health outcomes in adolescents.

Adolescence, defined as the period between 10 and 19 years of age, is a developmental stage during which many psychosocial and mental health challenges emerge. There is a well-established link between mental health and HIV outcomes. Adolescents and young adults living with HIV typically have additio...nal mental health needs linked to their experiences of living with and managing a chronic illness, along with prevailing stigma and discrimination. Mental health promotion and prevention is thus a critical priority for this group.
