Genetic and phenotypic associations of social isolation and loneliness with sarcopenia
Social isolation and loneliness are recognized risk factors for adverse aging outcomes, but their effects on sarcopenia remain understudied. This study investigated the independent and combined effects of social isolation and loneliness on the risk of incident sarcopenia in two large prospective cohorts: CHARLS (n = 8,856) and ELSA (n = 5,561), including participants aged 50 years and older free of sarcopenia at baseline. Sarcopenia was defined u…
Fatal crashes and rare events logistic regression: An exploratory empirical study
Objective: Fatal road accidents are statistically rare, posing challenges for accurate estimation through the classic logit model (LM). This study seeks to validate the efficacy of a rare events logistic model (RELM) in enhancing the precision of fatal crash estimations. Methods: Both LM and RELM were employed to examine the relationship between pertinent risk factors and the incidence of fatal crashes. Crash-injury datasets sourced from Hillsbor…
Mass Screening for Low Bone Density Using Basic Check-Up Items
Given the severe impact of low bone density (LBD) on public health, and to avoid the potential damage of X-rays-based bone density measurements, this study aimed to develop a scoring system for the mass screening for LBD in women aged 50 years or older, using the basic body check-up items as variables. Five variables, including age, body mass index (BMI), systolic blood pressure (SBP), blood glucose level, and total cholesterol level (TCL), were …
Social, lifestyle, and health status characteristics as a proxy for occupational burnout identification: A network approach analysis
This work demonstrated the feasibility of identifying people at risk of occupational burnout through an inferred colleague's social network. Encouraging staff with lower occupational burnout status to communicate with others may reduce the risk of burnout for other staff in the network
The Opportunities and Challenges of the First Three Years of Open Up, an Online Text-Based Counselling Service for Youth and Young Adults
We present the opportunities and challenges of Open Up, a free, 24/7 online text-based counselling service to support youth in Hong Kong. The number of youths served more than doubled within the first three years since its inception in 2018 in response to increasing youth suicidality and mental health needs. Good practice models are being developed in order to sustain and further scale up the service. We discuss the structure of the operation, us…
