Social isolation exacerbates physical frailty and is associated with subjective well-being. Even those with high levels of social isolation may have different health statuses depending on the type of isolation and their subjective well-being. However, the effect of subjective well-being on the relationship between social isolation and physical frailty remains unclear. This study examined whether the risk of physical frailty was the same for individuals with social isolation according to high and low subjective well-being. The study participants included 1,953 middle-aged Japanese adults aged 45 years and older. Physical frailty was assessed using a modified version of the Fried phenotype criteria. Probabilistic Latent Semantic Analysis was used to classify participants according to social isolation indicators. Subsequently, we focused on the groups with high social isolation and classified them according to whether their subjective well-being was high or low. Subjective well-being was evaluated using the Shiawase and Ikigai scales, which are concepts used in Japan. Finally, we used survival time analysis to examine the relationship between Shiawase or Ikigai and physical frailty in groups with high social isolation. The participants were classified into four groups based on their social isolation status. The physical frailty rate of the high social isolation class was 37.0%, which was significantly higher than that of the other classes. Survival time analysis revealed that among people with high social isolation, those with high Shiawase and Ikigai had a significantly lower risk of physical frailty than those with low Shiawase and Ikigai. All individuals with high social isolation are not at a high risk of physical frailty. The findings reveal that even those with high level of social isolation may have a lower risk of physical frailty if their subjective well-being is high. These results will contribute to promoting the prevention of frailty in middle-aged and older adults.

Background: Clinical situations marked by severe social withdrawal in youths are increasingly recognized as an important public health issue in European countries, while the relation with the hikikomori syndrome initially described in Japan remains poorly investigated.
Aims: This study aims to describe the sociodemographic features of adolescents and young adults with social withdrawal in French and to validate a French version of the Hikikomori Questiuonnaire-25 (HQ-25).
Method: An online questionnaire was completed by 450 participants aged 13 to 25 years.

A growing literature suggests that declines in sensory/perceptual systems predate cognitive declines in aging, and furthermore, they are highly predictive for developing Alzheimer's disease and Alzheimer's related dementias (ADRD). While vision, hearing, olfaction, and vestibular function have each been shown to be related to ADRD, their causal relations to cognitive declines, how they interact with each other remains to be clarified. Currently, there is substantial debate whether sensory/perceptual systems that fail early in disease progression are causal in their contributions to cognitive load and/or social isolation or are simply coincident declines due to aging.

Despite the recognized importance of social connections in Chinese culture, research on how childhood peer relationship deficits impact health later in life has been limited. This study aimed to investigate the association between childhood peer relationship deficits and the odds of disability among older Chinese adults and to explore the potential mediating roles of social isolation, loneliness, and cognitive function. Using the longitudinal sample of respondents aged 60 years and older in the China Health and Retirement Longitudinal Study 2013-2018 ( = 7133), the link between peer relationship deficits in childhood and disability in late life was assessed using marginal structural models, and the potential mediating effects of social isolation, loneliness, and cognitive function were examined by the inverse odds ratio weighting technique.

Background: COVID-19-related social restrictions provided an opportunity to evaluate the impact of social isolation on Parkinson's disease.
Objective: This study aimed to explore changes in social isolation and their associations with PD symptoms using the Lubben Social Network Scale-Revised (LSNS-R).
Methods: Data from 80 participants of the Early Parkinson's Disease Longitudinal Singapore cohort were collected from April 2019 to April 2023, covering the periods before and after the imposition of COVID-19 restrictions.

Objective: To evaluate the use of complementary and integrative medicine (CIM) among a low-income population with mental health diagnoses and to assess differences in social determinants of health (SDOH) on the basis of CIM use.
Patients And Methods: We surveyed patients with mental health diagnoses and/or substance use disorders during outpatient evaluations between August 11, 2020, and November 18, 2021, at a community behavioral health center in Rochester, MN. We measured knowledge of current CIM, interest in future use of CIM, and SDOH.
