To explore health professionals’ perspectives on the barriers and enablers of healthcare access for older adults in Cambodia.

A qualitative study based on semi-structured interviews conducted in Khmer, recorded, transcribed, translated into English and analysed using an abductive thematic analysis approach.

Phnom Penh, Cambodia.

A purposive sample of 11 health professionals serving in diverse roles and sectors participated in the study.

Three key barriers emerged: (1) institutional barriers, (2) patient-specific access barriers and (3) communication barriers. However, four key enablers were also identified: (1) supportive healthcare environment, (2) reaching out to improve access to health services, (3) peer and community engagement and (4) government direct support to access healthcare. Despite previous policy efforts, gaps in the implementation of healthcare services for older adults persist across all health facilities. Health professionals identified that improving healthcare access for older adults in Cambodia requires a multifaceted strategy involving proactive outreach, health promotion, financial assistance and stronger community and family support.

Effective policy implementation requires collaboration among stakeholders and the active involvement of older adults in programme design to enhance dignity and well-being in Cambodia’s ageing population.

Non-communicable diseases (NCDs), such as diabetes, cardiovascular diseases and cancer, are major global public health concerns. Diet quality—particularly the consumption of ultra-processed foods—has been associated with increased risk of NCDs. Traditional cohort studies are often expensive and logistically complex. The NutriNet-Brasil cohort leverages a web-based approach, offering a cost-effective and practical solution for comprehensive data collection and long-term follow-up.

Recruitments began in January 2020 through mass media, social media campaigns and collaborations with health organisations. Eligible participants are adults (aged ≥18 years) living in Brazil with internet access. Participants complete self-administered online questionnaires covering dietary intake, health status and other health determinants. Dietary assessment is based on the Nova classification system, which categorises foods by their level of processing.

Over 88 000 participants have completed the initial questionnaire. The cohort is predominantly women (79.9%) and highly educated (67.9% had completed higher education). The web-based design enabled the development and application of innovative dietary assessment tools, including the Nova24h and the Nova24hScreener, specifically designed to evaluate food processing levels. These tools have shown good performance in capturing dietary patterns and are central to the cohort’s aim. The online platform facilitates efficient recruitment, data collection and participant retention.

NutriNet-Brasil is pioneering the development of web-based cohort methodologies and instruments tailored to food processing research. Future work includes leveraging collaborations with national and international research centres to conduct multidisciplinary analyses and inform public health policies.

To identify effective interventions to lower cardiovascular disease (CVD) risk factors among Asian Indian (AI) immigrants.

As the second largest immigrant group in the USA, AI immigrants experience CVD prevalence rates as high as 13% among males and 4.4% among females; these rates are significantly higher than other Asian subgroups and the general US population. Despite extensive knowledge of CVD risk factors, there have been few cardioprotective interventions in this population.

Interventional studies of first-generation AI immigrants aged 18–70 years, conducted between 2000 and 2025, will be identified, including randomised controlled trials, factorial and cross-over designs, and cluster randomised trials. We will include AIs with and without a specific family history of CVD, or personal history of type 2 diabetes mellitus, hyperlipidaemia or obesity. Exclusion criteria include AIs born in the USA or visiting.

The Arksey and O’Malley methodology framework and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews will be used for analysis. A preliminary review of interventions to lower the CVD risk in AIs will guide the research questions (stage 1). Relevant articles published between 2000 and 2025 will be retrieved using electronic databases and search terms (stage 2). Two independent reviewers will select studies based on eligibility criteria (stage 3). Reviewers will determine eligibility status, screen full texts and retrieve relevant publications. Reviewers will extract data, capturing study design, sample characteristics, types of interventions, outcomes and key findings (stage 4). A summary of results will be presented (stage 5). The review will identify the most effective interventions, potential areas for future research and practical recommendations to improve CVD outcomes among AI immigrants.

Included studies will meet ethical standards in research. Findings will be disseminated through manuscripts, presentations at relevant conferences and community outreach programmes to promote effective interventions.
