Background: The optimal multimorbidity measures for predicting disability trajectories are not universally agreed upon. We developed a multimorbidity index among middle-aged and older community-dwelling Chinese adults and compare its predictive ability of disability trajectories with other multimorbidity measures.
Methods: This study included 17,649 participants aged ≥50 years from the China Health and Retirement Longitudinal Survey 2011-2018.
Background: Vision impairment has become a prominent public health issue worldwide. However, little is known about vision impairment prevalence trends among the oldest-old adults in China. This study aimed to examine 20-year trends in the prevalence of vision impairment among the oldest-old Chinese adults and explore the contributions of sociodemographic variables, health behaviours, and chronic conditions to the trends.

Method: A systematic search was undertaken of relevant databases for original articles published before April 2020. Random effect models were used to obtain pooled estimates of the associations between VI and cognitive outcomes (cognitive impairment and dementia) with subgroup analyses of VI measures, cross-sectional associations of VI with cognitive impairment, and longitudinal associations of baseline VI with incident cognitive impairment and dementia.
Objective: This study aimed to develop and validate a multimorbidity index using self-reported chronic conditions for predicting 5-year mortality risk.
Methods: We analyzed data from the Chinese Longitudinal Healthy Longevity Survey (CLHLS) and included 11,853 community-dwelling older adults aged 65-84 years. Restrictive association rule mining (ARM) was used to identify disease combinations associated with mortality based on 13 chronic conditions.
Article Synopsis
- This study focused on how different ways of measuring multimorbidity affect mortality rates in older Chinese adults.
- Data was collected from over 13,000 participants aged 65 and older between 2002 and 2018, analyzing factors like condition counts and patterns.
- It was found that those with multimorbidity had a higher risk of death, and trajectory-based measures were more effective for predicting mortality than simpler count or pattern measures.
Article Synopsis
- * Data from 18,002 participants indicated that 24.5% had multiple CMDs, and those with more CMDs generally experienced higher depressive symptoms, especially if they had specific conditions like stroke or diabetes.
- * The research suggests the need for personalized mental health care strategies for older adults with these conditions, focusing on both individual CMDs and their combinations to improve treatment outcomes.
A Method for Detecting and Analyzing Facial Features of People with Drug Use Disorders.
Diagnostics (Basel)
August 2021
Drug use disorders caused by illicit drug use are significant contributors to the global burden of disease, and it is vital to conduct early detection of people with drug use disorders (PDUD). However, the primary care clinics and emergency departments lack simple and effective tools for screening PDUD. This study proposes a novel method to detect PDUD using facial images.

J Med Internet Res
September 2020
Background: The World Health Organization recommended HIV self-testing (HIVST) for individuals practicing unsafe sexual behaviors; however, the adherence to HIV testing has not been reported.
Objective: In this study, we attempted to determine the adherence to HIVST among men who have sex with men (MSM), as well as the impact factors and potential effects of their adherence.
Methods: We conducted a longitudinal study among MSM in Harbin, Heilongjiang province, China from July 1, 2017 to June 30, 2018.
Background: Recently, more and more men who have sex with men (MSM) look for casual partners through online dating platforms in China. However, most are unable to know their partners' HIV and other sexually transmitted diseases (STD) statuses, leading to the rapid increase in HIV infection among Chinese MSM. Effective partner notification is urgently needed to increase the risk awareness of MSM and prevent HIV and other STDs transmission.

: Evidence on the association between physical performance and multimorbidity is scarce in Asia. This study aimed to identify multimorbidity patterns and their association with physical performance among older Chinese adults. : Individuals aged ≥60 years from the China Health and Retirement Longitudinal Study 2011-2015 ( = 10,112) were included.
View Article and Find Full Text PDFObjectives: Depressive symptoms are commonly seen among patients with multiple chronic somatic conditions, or somatic multimorbidity (SMM); however, little is known about the relationships between depressive symptoms and different SMM combinations. Our study aimed to delineate the patterns of SMM and their longitudinal associations with depressive symptoms among a nationally representative sample of middle-aged and older Chinese adults.
Design: We employed a longitudinal design.
