Where do older adults and people with disabilities evacuate during flood disasters? A qualitative study in Japan
Incidence of depressive symptoms and their associations with lifestyle and social support networks among community-dwelling older adults
BACKGROUND: Primary prevention of depressive symptoms among independent older adults is a critical public health challenge. Lifestyle factors and social support networks are increasingly recognized as pivotal determinants of mental health in this population. However, few longitudinal studies have examined these relationships, and little attention has been directed to gender-based differences. We investigated the associations between lifestyle fac…
Social disconnection and suicide mortality among Japanese older adults
Avoidance of not only depressive symptoms, but also social disconnection including eating alone, is useful in suicide prevention among older adults
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
Family Pharmacy and Medication Adherence Among Older Adults in Japan
Older adults who "always received medicines from the same pharmacy" had a lower prevalence of unused medicines, especially those with low levels of education. Thus, "always receiving medicines from the same pharmacy" may be effective in reducing the proportion of unused medicines and improving medication adherence
Suicidal ideation and suicide attempts among older recipients of public welfare assistance in Japan
BACKGROUND: The high suicide rate among older adults is an important public health issue. Financial insecurity has been linked to suicidal behaviour. Despite this, as yet, there has been little research on suicide-related behaviours among older recipients of public welfare. This study will examine if suicidal ideation and suicide attempts are more prevalent in older recipients of public welfare assistance in Japan. METHODS: This cross-sectional s…
Physical Activity and Cumulative Long-Term Care Cost among Older Japanese Adults
This study aimed to determine the impact of physical activity on the cumulative cost of long-term care insurance (LTCI) services in a cohort of community-dwelling people (65 years and older) in Japan. Using cohort data from the Japan Gerontological Evaluation Study (JAGES) on those who were functionally independent as of 2010/11, we examined differences in the cumulative cost of LTCI services by physical activity. We followed 38,875 participants …
Associations between Healthcare Resources and Healthy Life Expectancy
Japan has the highest life expectancy in the world. However, this does not guarantee an improved quality of life. There is a gap between life expectancy and healthy life expectancy. This study aimed to reveal the features of healthy life expectancy across all secondary medical areas ( n = 344) in Japan and examine the relationship among healthcare resources, life expectancy, and healthy life expectancy at birth. Data were collected from Japan's p…
Is the Association between Green Tea Consumption and the Number of Remaining Teeth Affected by Social Networks
Consumption of green tea without sugar, as well as social networks, are associated with a lower risk of tooth loss. There is a possibility of confounding both factors because tea is often drunk with friends. Therefore, the present study aimed to examine whether green tea consumption is beneficially associated with the number of remaining teeth, while considering social networks. This cross-sectional study was based on the Japan Gerontological Eva…
Does the Association between Guardians’ Sense of Coherence and their Children’s Untreated Caries Differ According to Socioeconomic Status
Untreated caries is the most prevalent disease in the world. A sense of coherence (SOC) is believed to contribute to oral health. We aimed to clarify the association between guardians' SOC and their children's caries based on socioeconomic status (SES) in Japan. This study's subjects were Japanese public junior high schoolers (N = 1730), aged 12-15, and their guardians in Kosai City. We administered a questionnaire survey among guardians in 2016 …
Correlations between Forgetfulness and Social Participation
We analyzed the relationships between forgetfulness and social participation, social contact, and social support by municipality to develop community diagnosing indicators. The analysis subjects included 105 municipalities that agreed to provide data for the 2013 Survey of Needs in Spheres of Daily Life in Japan ( n = 338,659 people). Forgetfulness as a risk factor for dementia was used as the dependent variable. The variables of social environme…
Harmonising summary measures of population health using global survey instruments
measures of population health—health expectancies in particular—have become a standard for quantifying and monitoring population health. To date, cross-national comparability of health expectancies is limited, except within the European Union (EU). To advance international comparability, the European Joint Action on Healthy Life Years (JA: EHLEIS) set up an international working group. The working group discussed the conceptual basis of summary m…
Access Disparity and Health Inequality of the Elderly
The purpose of this study is to investigate healthcare access disparity that will cause delayed and unmet healthcare needs for the elderly, and to examine health inequality and healthcare cost burden for the elderly. To produce clear policy applications, this study adapts a modified PRECEDE-PROCEED model for framing theoretical and experimental approaches. Data were collected from a large collection of the Community Tracking Study Household Surve…
Combined effects of eating alone and living alone on unhealthy dietary behaviors, obesity and underweight in older Japanese adults
We examined whether eating alone is associated with dietary behaviors and body weight status, and assessed the modifying effects of cohabitation status in older Japanese people. Data from the 2010 Japan Gerontological Evaluation Study, with a self-reported questionnaire for 38,690 men and 43,674 women aged ≥65 years, were used. Eating status was classified as eating with others, sometimes eating alone, or exclusively eating alone. We calculated a…
Relative deprivation in income and mortality by leading causes among older Japanese men and women
BACKGROUND: Relative deprivation of income is hypothesised to generate frustration and stress through upward social comparison with one's peers. If psychosocial stress is the mechanism, relative deprivation should be more strongly associated with specific health outcomes, such as cardiovascular disease (compared with other health outcomes, eg, non-tobacco-related cancer). METHODS: We evaluated the association between relative income deprivation a…
Long-term impact of the 2011 Great East Japan Earthquake and tsunami on functional disability among older people
It has been unclear whether the prevalence of disability is higher in an area affected by natural disaster than in other areas even if more than one year has passed since the disaster. The aim of this ecological study was to examine whether the rate of increase in disability prevalence among the older population was higher in disaster-stricken areas during the 3 years after the Great East Japan Earthquake (GEJE) and tsunami. This analysis used pu…
Gender differences on the impacts of social exclusion on mortality among older Japanese
Barriers to Health Care among the Elderly in Japan
Japan is undergoing a set of health care reforms aimed at cutting rising health care costs and increasing the efficiency of health care delivery. This empirical study used a large-scale community survey on 15,302 elderly people 65 years and older (56.0% women) conducted in seven municipalities in 2006, to reveal clear-cut evidence of barriers to necessary care. The reasons for not getting health care is attributed to health care cost for the elde…
The health impact of remarriage behavior on chronic obstructive pulmonary disease
This study investigates the impact of remarriage on health outcome based on a large-scale population survey and indicates that remarriage significantly correlates with reduced risk of COPD incidence, even after adjusting smoking habit
Association between depression and socio-economic status among community-dwelling elderly in Japan
Administration of hepatitis B vaccine in winter as a significant predictor of the poor effectiveness of vaccination in rural Mongolia
Background: Universal hepatitis B (HB) immunisation is the most effective means for prevention of hepatitis B virus (HBV) infection worldwide. Maintaining the vaccine cold chain is an essential part of a successful immunisation programme. Our recent nationwide survey in Mongolia has observed significant urban–rural differences in the prevalence of HBV infection among vaccinated cohorts. Objective: To examine whether the administration of HB vacci…
