In response to the distinctive healthcare requirements of independent, healthy, community-dwelling older adults in Japan and other developed countries with aging populations, the current study examined the differences in factors associated with self-rated health (SRH) between the following two age groups: young–old (65–74) and old–old (75 and above). Age-stratified analysis was used to provide a comprehensive understanding of the unique health challenges faced by these demographic segments and to inform the development of targeted interventions and health policies to improve their well-being. The results of a cross-sectional study of 846 older adults in Yokohama, Japan, who completed self-administered questionnaires, revealed that high SRH was consistently linked with the low prevalence of concurrent medical issues in both age groups (<75 and ≥75) (β: −0.323, p < 0.001 in the <75 group; β: −0.232, p < 0.001 in the ≥75 group) and increased subjective well-being (β: 0.357, p < 0.001 in the <75 group; β: 0.244, p < 0.001 in the ≥75 group). Within the ≥75 age group, higher SRH was associated with more favorable economic status (β: 0.164, p < 0.001) and increased engagement in social activities (β: 0.117, p = 0.008), even after adjusting for age, sex, and economic status. These findings may inform the development of targeted interventions and policies to enhance the well-being of this growing population in Japan and other developed countries.

Background: Community health workers (CHWs), hailing from the general populace, play a pivotal role in fortifying healthcare systems, with a primary focus on mitigating non-communicable diseases (NCDs) and elevating overall life expectancy. To assess the aptitude of CHWs in NCD prevention, we introduced the Community Health Workers Perceptual and Behavioral Competency Scale for preventing non-communicable diseases (COCS-N). This study examines the multifaceted interplay of individual and community factors that influence CHWs’ COCS-N scores. Methods: The research design is a secondary analysis using data from a self-administered questionnaire survey of 6480 CHWs residing in municipalities across Japan, which obtained 3120 valid responses, between September to November 2020. The COCS-N was employed as the dependent variable, while the independent variables were individual-related factors, including years of community health work, health literacy, and community-related factors, such as CHWs’ sense of community. To ascertain the significance of associations between individual and community factors and CHWs’ competency, an analysis of covariance (ANCOVA) was utilized to compare the three groups Q1/Q2/Q3 by low, medium, and high scores on the COCS-N scale. Statistical significance was considered to be indicated by a p-value of less than 0.05. Results: The ANCOVA analysis revealed that three factors were significantly linked to CHWs’ competence. These comprised individual factors: “years of CHWs” (mean ± SD Q1: 6.0 ± 6.0, Q2: 7.8 ± 7.0, Q3: 8.2 ± 7.7, p < 0.001) and “health literacy” (Q1: 27.7 ± 6.6, Q2: 30.4 ± 6.9, Q3: 33.8 ± 7.8, p < 0.001), as well as a community factor: “Sense of community” (Q1: 14.8 ± 3.7, Q2: 16.5 ± 3.5, Q3: 18.2 ± 3.6, p < 0.001). Conclusions: Our finding is that a positive association was derived between COCS-N scores and certain determinants. Notably, “years of CHWs” and “health literacy” in the individual domain, along with the “Sense of community” in the communal context, were firmly established as being significantly associated with CHWs’ competency. Consequently, CHWs need training to increase their “health literacy” and “sense of community”, to acquire high competency in NCD prevention, which will lead to the empowerment of CHWs and maintain their motivation to continue.

(1) Background: Loneliness is inherently linked to social connections, with interpersonal communication playing a pivotal role. Despite this connection, limited research exists on the relationship between loneliness and communication among young adults. This study investigates the correlation between face-to-face, telephone, and online communication frequencies and loneliness among individuals in their 20s. (2) Methods: Using a dataset from a nationwide survey conducted by the Japanese Cabinet Office, this study focuses on 1812 respondents aged 20–30, selected from a random sample of 20,000 individuals aged 16 and older across Japan. (3) Results: A Multivariate Logistic Regression Analysis reveals a significant association between communication frequency and loneliness, even after adjusting for demographic characteristics. Notably, decreased communication frequency across all modalities correlated with increased loneliness. Online communication exhibited the highest impact, followed by face-to-face communication, with phone call communication ranking last. (4) Conclusions: This study emphasizes the importance of seamlessly integrating social networking service (SNS)-based communication with various forms of social interaction. A well-balanced integration of these approaches is crucial for mitigating loneliness among young individuals and promoting positive mental health outcomes.

Population aging has increased reliance on family carers, whose psychosocial burdens and support needs vary by life stage. This exploratory study aimed to compare psychosocial care burdens and support needs between middle-aged family carers (MFCs) and older family carers (OFCs) providing home-based care in Japan from a life-stage perspective. A cross-sectional survey was conducted among family carers registered with a community general support center in Sapporo, Japan. Data from 153 respondents were analyzed. Psychosocial care burden was assessed across perceived burden, underlying causes, and broader life challenges. Support needs were evaluated based on preferences for 20 types of services and supports. Overall, 60% of MFCs and 53.9% of OFCs experienced care burden. MFCs reported significantly greater burdens related to family relationships (Cramer’s V = 0.168) and work-related concerns (Cramer’s V = 0.235). They also expressed higher needs for Care Leave Accessibility, Flexible Work for Care, and Carer Job Support, with small-to-moderate effect sizes. The findings suggest that psychosocial burdens and support needs among family carers may vary across different age-defined life stages. Middle-aged carers balancing work and family responsibilities face distinct challenges, underscoring the need for targeted policies, workplace support, and life-stage-responsive, role-sensitive support systems in aging societies.
