Background: Non-adherence to lipid-lowering agents poses significant risks to patients and diminishes treatment effectiveness. Current understanding of patients' preferences regarding the characteristics of these agents is limited. This study aims to qualitatively identify the barriers to lipid-lowering medication adherence and the factors considered by patients with hypercholesterolemia when choosing lipid-lowering agents, and to inform the design of a medication preference study.

Introduction: The evolving landscape of general practice (GP)/family medicine (FM) in the post-COVID-19 era, focussing on integrating telemedicine and remote consultations requires a new definition for this specialty. Hence, a broader consensus-based definition of post-COVID-19 GP/FM is warranted.

Methods: This study involved a modified electronic Delphi technique involving 27 specialists working in primary care recruited via convenient and snowball sampling.

Article Synopsis
  • The study investigates how exposure to particulate matter (PM2.5) throughout different life stages influences the risk of developing prediabetes and diabetes in adults, highlighting the urban health challenge of air pollution.
  • It involved 4,551 participants from Taiwan and Hong Kong, assessing PM2.5 exposure using satellite data and linking it to medical visits over nearly 10 years.
  • Results showed that each increase of 10 μg/m3 in PM2.5 exposure was associated with higher odds of prediabetes/diabetes, with exposure during adulthood posing a slightly greater risk than exposure during earlier life stages.

Background: Cervical cancer is a global health threat and a manifestation of inequality, and screening is an effective intervention. However, little is known about how screening coverage and quality assurance, influence cervical cancer mortality. We aimed to investigate the association between screening coverage, screening quality assurance and cervical cancer mortality among women from countries at different developmental levels.

Pneumococcal vaccination (PV) is effective in preventing vaccine-type pneumococcal diseases. This study investigated the changes in PV uptake and its determinants before, during, and after the Coronavirus Disease 2019 (COVID-19) pandemic among community-living older adults aged ≥65 years in Hong Kong, China. Three rounds of random telephone surveys were conducted every two years from May 2019 to October 2023.

Objective: To determine a risk scoring system for predicting advanced colorectal neoplasia (ACN) within subcentimetric polyps in a large Asian population.

Methods: A retrospective study was conducted in Hong Kong SAR, China involving participants who underwent colonoscopy between 2008 and 2015. A random sample of 20 072 subjects were included as the derivation cohort to assess ACN-associated independent factors using logistic regression modeling.

Background: Most liver cancer scoring systems focus on patients with preexisting liver diseases such as chronic viral hepatitis or liver cirrhosis. Patients with diabetes are at higher risk of developing liver cancer than the general population. However, liver cancer scoring systems for patients in the absence of liver diseases or those with diabetes remain rare.

Article Synopsis
  • - The study investigates obesity prevalence among children in Hong Kong, focusing on primary and secondary school students, and aims to identify associated risk factors linked to sociodemographic and health-related behaviors.
  • - Data was gathered through self-administered surveys from nearly 5,000 students across 55 schools, revealing that obesity is more common in male students, particularly those with poor academic performance and unhealthy lifestyle habits, like high sugary drink consumption and low physical activity.
  • - Key findings suggest that male gender, inactivity, low self-esteem in academics, and poor dietary choices are significant risk factors for obesity, underlining the need for targeted interventions for at-risk youth and further research on effective solutions.

Purpose: Osteoporosis is an important public health challenge given its high prevalence in western populations and the prevalence has shown an upward trend in recent decades in Asia. However, epidemiological evidence on the association between bone mineral density (BMD) and mortality risk in the Asian population is sparse.

Methods: The Cox proportional hazards model and cause-specific hazard models were used to investigate the association of BMD with the risk of all-cause mortality and cause-specific mortality.
