The effects of physical activity (PA) across different domains and intensities on depressive symptoms remain inconclusive. Incorporating the community-built environment (CBE) into longitudinal analyses of PA’s impact on depressive symptoms is crucial.

The association between social media usage and risk of depressive symptoms has attracted increasing attention. WeChat is a popular social media in China. It is not confirmed and conflicting that the impact of using WeChat and posting WeChat moments on the risk of depressive symptoms among community-based middle-age and elderly in China.

Although agricultural health has gained importance, to date, much of the existing research relies on traditional epidemiological approaches that often face limitations related to sample size, geographic scope, temporal coverage, and the range of health events examined. To address these challenges, a complementary approach involves leveraging and reusing data beyond its original purpose. Administrative health databases (AHDs) are increasingly reused in population-based research and digital public health, especially for populations such as farmers, who face distinct environmental risks.

Population size estimation (PSE) for key populations is needed to inform HIV programming and policy.

High response rates are needed in population-based studies as non-response reduces effective sample size and bias affects accuracy and decreases generalizability of the study findings.

India is committed to malaria elimination by the year 2030. According to the classification of malaria endemicity, the National Capital Territory of Delhi falls under category 1 with an Annual Parasite Incidence of <1 and was targeted for elimination by 2022. Among others, population movement across states is one of the key challenges for malaria control as it can result in imported malaria, thus introducing local transmission in an area nearing elimination.

Stimulants are potent treatments for Central Hypersomnolence Disorders (CHD) or Attention Deficit Disorders (ADHD/ADD) but concerns have been raised about their potential negative consequences and their increasing prescription rates.

Liver cancer continues to pose a significant burden in China. To enhance the efficiency of screening, it is crucial to implement population stratification for liver cancer surveillance.

There is limited literature available regarding the acceptance of HIV pre-exposure prophylaxis (PrEP) cascade services among men who have sex with men with sexually transmitted infections (MSM-STIs).

A recent infection testing algorithm (RITA) incorporating case surveillance (CS) with the rapid test for recent HIV infection (RTRI) was integrated into HIV testing services in Thailand as a small-scale pilot project in October 2020.

Convenience, privacy, and cost-effectiveness associated with web-based data collection has facilitated the recent expansion of online survey research. Importantly, however, practical benefits of online survey research, to scientists and participants alike, are being overshadowed by the dramatic rise in suspicious and fraudulent online survey submissions. Misinformation associated with online survey fraud compromises data quality and data integrity with important implications for scientific conclusions, clinical practice, and social benefit. Transparency in reporting on methods used to prevent and manage suspicious and fraudulent submissions is key to protecting the veracity of online survey data; yet there is limited discussion on the use of anti-deception strategies during all phases of survey research to detect and eliminate low-quality and fraudulent responses.

Prisoner health is a major global concern, with prisoners often facing limited access to healthcare and suffering from chronic diseases, infectious diseases, and poor mental health due to unsafe prison environments, unhygienic living conditions, and inadequate medical resources. In Taiwan, prison health is an increasing issue, particularly concerning urinary diseases such as urinary tract infections (UTIs). Limited access to healthcare and unsanitary conditions exacerbate these problems. Urinary disease epidemiology varies by sex and age, yet, studies in Asia are scarce, and comprehensive data on urinary diseases in Taiwanese prisons remain limited.
