Nutrition risk is prevalent in community-dwelling older adults, and leads to increased morbidity and mortality. Understanding the factors associated with the development of high nutrition risk is crucial for the development of appropriate programs and policies to address this problem. Therefore, our objective was to identify the psychosocial factors correlated with the development of high nutrition risk, as assessed by SCREEN-8, among Canadian adults categorized by ten-year age groups (45–54, 55–64, 65–74, and 75+). We used data from 17,051 participants in the tracking cohort of the Canadian Longitudinal Study on Aging and employed multivariable binomial logistic regression to identify the social and demographic factors associated with the emergence of high nutrition risk at follow-up, three years after the baseline. Baseline data were gathered between 2011 and 2015. At baseline, 34.4% of participants across all age groups were at high nutrition risk, while 40.0% were at high risk at follow-up. Factors consistently associated with the development of high nutrition risk across all age groups included lower levels of social support, lower self-rated social standing, infrequent participation in sports or physical activities, infrequent participation in cultural or educational activities, and lower household incomes. Programs and policies addressing these factors may reduce the prevalence of high nutrition risk and the development of high nutrition risk.

Purpose: Cross-sectional analysis using open data has revealed an association between the traditional Japanese diet score (TJDS) and healthy life expectancy (HALE). This study aimed to clarify the association of the TJDS with the HALE and average life expectancy (LE) via a longitudinal analysis. Methods: Data regarding the food supply and total energy were extracted from the database of the Food and Agriculture Organization of the United Nations, and data regarding HALE and LE were obtained from the Global Burden of Disease Study 2019. The supply of items consumed frequently (rice, fish, soybeans, vegetables, and eggs) and less frequently (wheat, milk, and red meat) in the Japanese diet were scored (total: −8 to 8 points) and stratified into tertiles by country. The gross domestic product, aging rates, years of education, smoking rate, physical activity, and obesity rate were used as covariates. Longitudinal analyses were conducted for 143 countries, using the HALE and LE for each country from 2010 to 2019 as dependent variables and the 2010 TJDS as an independent variable. Results: The fixed effects (standard errors) were HALE 0.424 (0.102) and LE 0.521 (0.119), indicating significance (p < 0.001). Conclusion: The nine-year longitudinal analysis using international data suggests that the traditional Japanese diet based on rice may prolong the HALE and LE.

This article addresses selected issues concerning the formulation and implementation of public policies on aging both at the global and regional levels. Selected key initiatives undertaken by the World Health Organization (WHO), the United Nations (UN), and the European Union (EU) are discussed. The article further examines three distinct models of aging policy as exemplified by Norway, Lithuania, and Poland. These countries share commonalities, including very high rates of demographic aging and membership in the Organization for Economic Co-operation and Development (OECD). However, each nation adopts a different model of social policy, consequently reflecting diverse models of senior citizen support. The research aims to elucidate the determinants and impacts of social policies targeting a particularly vulnerable segment of the population—older adults requiring long-term services and support. Central to this investigation is the comparative analysis of general characteristics distinguishing the different national models. This was achieved through a synthesis and evaluation of selected quantitative and qualitative indicators. Methodologically, the study utilizes expert interviews, comprehensive literature reviews, secondary analyses of international and national statistical data, including data from Eurostat and OECD databases, European Commission policy documents, and an extensive review of grey literature encompassing pertinent Internet sources. Findings reveal marked differences in the design and execution of aging policies across the three countries, highlighting variations in how the welfare function of the state is operationalized in addressing the needs of the elderly.
