Living in High-Rise Apartments and the Frequency of out-of-Home Activities Among Community-Dwelling Older Adults
Examination of How Mall Visits Moderate the Impact of Adverse Weather on Daily Step Counts
Climate change has led to an increase in extreme weather events. Adverse weather conditions limit outdoor activities, reduce step counts, and negatively affect health. Malls offer a possible alternative for walking in such weather; however, their step-loss mitigating role remains unexplored. We analyzed data from 18,666 individuals aged ≥ 18 years (mean ± standard deviation: 48.0 ± 12.6; women: 71.5%), tracking daily step counts over a year using…
Neighborhood walkability and subsequent health and well-being in urban and rural Japan
Paradoxical effects of community social cohesion on mental health and help-seeking among older adults
There is no consensus on whether community social cohesion has positive or negative impacts on mental health. In this study, we hypothesized that strong social norms in highly cohesive communities might increase concerns about reputation, which could negatively affect mental health and help-seeking. We analyzed data from 23,672 adults aged 65 years or older from the 2019 wave of the Japan Gerontological Evaluation Study (JAGES). Cross-sectional m…
Does the neighborhood built and social environment reduce long-term care costs for Japanese older people? The Jages2010-2019 cohort study
Japan's population has been aging steadily, evidenced by it spending JPY 11 trillion (USD 110 billion) on annual long-term care (LTC) costs in 2021. In this context, understanding the factors influencing LTC costs has become increasingly vital. Although studies have reported positive relationships between neighborhood environment and health outcomes, the connection between LTC costs and neighborhood environment remains unclear. To address this ga…
Does disaster-related relocation impact mental health via changes in group participation among older adults? Causal mediation analysis of a pre-post disaster study of the 2016 Kumamoto earthquake
Optimization of social ties according to a renewal of group participation status might have protected older adults in temporary housing against depression
Association of community-level social capital with dementia
Internet use and subsequent health and well-being in older adults
The association between elder abuse and refrainment from daily activities during the Covid-19 pandemic among older adults in Japan
The risk of elder abuse increased as the number of refrained behaviors increased which suggests that refrainment from multiple behaviors may significantly increase the risk of elder abuse, compared with refrainment from a single behavior. To avoid increasing the risk of abuse in likely future pandemics, it is necessary to maintain social connections without face-to-face contact, or with adequate infection control measures
Neighborhood Beauty and the Brain in Older Japanese Adults
People have a preference for, and feel better in, beautiful natural environments. However, there are no epidemiological studies on the association between neighborhood beauty and neuroimaging measures. We aimed to determine association between neighborhood beauty and regional brain volume. Participants were 476 community-dwelling older adults from the Neuron to Environmental Impact across Generations (NEIGE) study. Subjective neighborhood beauty …
Comparison of three indices of relative income deprivation in predicting health status
Community-Level Participation in Volunteer Groups and Individual Depressive Symptoms in Japanese Older People
Older people living in areas with higher volunteer group participation had a lower risk of developing depressive symptoms regardless of whether or not they participated in a volunteer group
Assessment of Personal Relaxation in Indoor-Air Environments
The relationship between chemical concentrations in indoor air and the human sense of comfort and relaxation have been reported. We investigated the effect of the sum of volatile organic compounds (ΣVOCs; sum of 79 VOCs) on the level of relaxation in two laboratory houses with almost identical interior and exterior appearances. The electroencephalogram (EEG) was monitored to evaluate the degree of personal relaxation objectively. The experiments …
Association between Proximity of the Elementary School and Depression in Japanese Older Adults
Depression among older adults is one of the most critical public health issues. The proximity of elementary schools has been positively associated with neighborhood social cohesion and quality of life. However, no studies have identified an association between the proximity of elementary school and older adults' mental health. Therefore, this study aimed to examine the association between the proximity of elementary schools, one of the core facil…
Neighborhood farm density, types of agriculture, and depressive symptoms among older farmers
The high prevalence of depressive symptoms among farmers in neighborhoods with a low farm density may reflect a scarcity of formal and informal social support in such communities. The health effects of the neighborhood environment on farmers, such as farm density, which may vary by the type of agriculture, should be further researched
What Types of Greenspaces Are Associated with Depression in Urban and Rural Older Adults? A Multilevel Cross-Sectional Study from Jages
Depression in older adults is a public health challenge. We aimed to clarify the relationship between depression in older adults and three types of neighborhood greenspaces: trees, grasslands, and fields. We utilized data from the Japan Gerontological Evaluation Study (JAGES) performed in 2016. Multilevel logistic regression analysis was used for non-stratified and stratified analyses for the urban-rural regions. The target population comprised 1…
Concentrations of Formic Acid, Acetic Acid, and Ammonia in Newly Constructed Houses
Herein, the concentrations of formic acid, acetic acid, and ammonia in samples of indoor air for 47 new houses were measured two weeks after completion. The houses were fabricated with light-gauge steel structures. The measurements were performed in living rooms and bedrooms without furniture and outdoors. Air samples were analyzed using ion chromatography. The mean values were 28 (living room), 30 (bedroom), and 20 μg m -3 (outdoor air) for form…
Three-Year Longitudinal Association Between Built Environmental Factors and Decline in Older Adults’ Step Count
This study examined the longitudinal association between the change in the step count of older adults and the neighborhood-built environment (BE) in Yokohama, Japan. We analyzed pedometer data in March 2016 and March 2019 that were acquired from 21,557 older adults aged 65-79 years at baseline, who lived in 758 neighborhoods in Yokohama City and participated in the Yokohama Walking Point Program (YWPP). Six BE variables were computed, for each of…
Does community-level social capital mitigate the impact of widowhood & living alone on depressive symptoms
Indoor Air Quality Analysis of Newly Built Houses
Recently, people have become increasingly aware of potential health issues related to indoor environments. In this study, we measure the concentrations of various volatile organic compounds, carbonyl compounds, and semi-volatile organic compounds, as well as the ventilation rates, in 49 new houses with light-gauge steel structures one week after completion. The proper indoor air quality of new residential environments can be ensured by characteri…
Modal Shift from Cars and Promotion of Walking by Providing Pedometers in Yokohama City, Japan
Mobility management is a transportation policy aiming to change travel behavior from car use to sustainable transportation modes while increasing people's physical activity. Providing pedometers and visualizing step counts, popular interventions in public health practice, may constitute a mobility management program. However, the ease of modal shifts and changeability of walking habits differ across neighborhood environments. Using questionnaire …
Comparison of Objective and Perceived Access to Food Stores Associated with Intake Frequencies of Vegetables/Fruits and Meat/Fish among Community-Dwelling Older Japanese
This cross-sectional study aimed to compare access to the nearest food stores with perceived access associated with intake frequencies of vegetables/fruits and meat/fish among older Japanese people. We used intake frequencies of vegetables/fruits and meat/fish from a self-administered questionnaire in the Japan Gerontological Evaluation Study among 83,384 adults aged over 65 years. We defined distance over 1 km as poor objective access in communi…
Neighborhood Walkability in Relation to Knee and Low Back Pain in Older People
Few studies have focused on a relationship between the built environment and musculoskeletal pain. This study aimed to investigate an association between neighborhood walkability and knee and low back pain in older people. Data were derived from the Japan Gerontological Evaluation Study (JAGES) 2013, a population-based study of independently living people ≥65 years old. A cross-sectional multilevel analysis was performed, of 22,892 participants i…
