  • Machine learning-based prediction of occupational exposure risks among oral healthcare workers

    Open AccessJinting Zhu, Lan Wang et al.ARTICLEFrontiers in Public Health2026

    Objective: This study aims to identify the key risk factors for occupational exposure among oral healthcare workers and develop a predictive model using machine learning algorithms to lay the foundation for early screening of high-risk populations and the formulation of preemptive intervention plans. Methods: A multicenter cross-sectional study was conducted among 367 oral healthcare workers in 27 hospitals in Tianjin, China, from January 2025 to…

  • Effectiveness of a harmonica-integrated, tele-supervised home-based pulmonary rehabilitation program on lung function and comprehensive health outcomes in patients with chronic obstructive pulmonary d…

    Open AccessQiuxuan Zeng, Xiaohong Lin et al.ARTICLEFrontiers in Public Health2025

    Introduction Harmonica playing mimics pursed-lip breathing and strengthens respiratory muscles. Combined with music therapy, it may improve both pulmonary and mental health in chronic obstructive pulmonary disease (COPD) patients, though its effects are not well understood. This protocol outlines a randomized controlled trial (RCT) to evaluate the effectiveness of integrating harmonica playing into pulmonary rehabilitation (PR) programs. Methods …

  • Alcohol use and physical functioning among older adults in China

    Yanhua Zhu, Fanghong Dong et al.ARTICLEJournal of Ethnicity in Substance…2025

    These findings indicate possible domain-specific effects of alcohol use on physical functioning. Alcohol should not be viewed as beneficial for strength. Clinicians should routinely assess older adults' alcohol use and help them with alcohol reduction. This may reduce alcohol use, improve balance in older adults

  • Cognitive frailty and pre-cognitive frailty in Chinese middle-aged and older adults

    Open AccessHongting Ning, Hui Feng et al.ARTICLECritical Public Health2025

    The age-specific prevalence, risk factors, and magnitude of the association between cognitive frailty and mortality in middle-aged and older adults remains unclear. We used baseline (2011) and follow-up wave (2013, 2015, and 2018) data from the China Health and Retirement Longitudinal Study (CHARLS). The age group was categorized as middle-aged, old, and very old. Factors associated with cognitive frailty and the associations between cognitive fr…

  • Association of Sleep and Physical Activity Among Older Adults and the Moderation of Chronotype

    Open AccessJing Huang, Mengchi Li et al.ARTICLEThe International Journal of…2023

    This study aimed to examine the associations of both subjectively and objectively measured sleep with physical activity among older adults and to explore the possible moderating role of chronotype in these associations. We included baseline data of 116 community-dwelling older adults without dementia from three prior studies. Pittsburgh Sleep Quality Index and Actigraphy were used as subjective and objective sleep measures, respectively. Physical…

  • Assisted Relaxation Therapy for Insomnia in Older Adults With Mild Cognitive Impairment

    Open AccessMiranda McPhillips, Junxin Li et al.ARTICLEThe International Journal of…2023

    Insomnia symptoms are prevalent in older adults with mild cognitive impairment (MCI) and can pose treatment challenges. We tested the feasibility, acceptability, and preliminary efficacy of assisted relaxation therapy (ART) to improve insomnia symptoms in community-dwelling older adults with MCI. In this pilot RCT, 25 participants were assigned to intervention or control groups for 2 weeks. The final sample ( n = 20) consisted of all Black, prima…

  • Electronic Wearable Device Use for Physical Activity in Older Adults

    Open AccessMengchi Li, Miranda McPhillips et al.ARTICLEWork Aging and Retirement2022References: 4

    Innovative solutions to help older adults increase physical activity are critically important. In this qualitative study, we explored older adults' acceptance, capability, and experiences of using three different types of electronic wearable devices over a period of 4-24 weeks for self-monitoring and promoting physical activity. We conducted 23 semistructured interviews with older adults who participated in three physical activity intervention st…
