Aging in Rural Communities

Barriers to Healthcare and Social Service Utilization Among Rural Older Adults Who Use Drugs

The objective of this study was to understand barriers to healthcare and social service utilization among older adults residing in rural areas who use drugs. A cross-sectional survey of persons who use opioids or inject drugs in rural counties with high overdose rates across ten states was conducted. For this analysis, participants were restricted to only the 375 individuals aged 50 and older. They were asked about barriers to utilizing healthcare and social services. Multivariate analyses were conducted. The most common barriers were a lack of transportation and a fear of stigma. The average number of barriers was 2.53. Those who were either uninsured or homeless endorsed 37% more barriers. For every five-year increase in age, the number of barriers reduced by 15%. Efforts to reduce these barriers may include expanding eligibility for transportation and housing services and leveraging trusted community members to broker linkages to providers to overcome stigma.

Demographic Disparities in Drive Times to the Nearest Audiologist in the United States

PURPOSE

Audiological services are underused, possibly because patients need to drive long distances to see a provider. In this study, we measured the association of drive times to the nearest audiologist with population density, income, ethnicity, race, and distance to the nearest audiology graduate program.

METHOD

Drive times for each census block group to the nearest audiologist were measured using census data, the National Provider Identifier Registry, and a geographic analyzing tool called ArcGIS for all block groups within the United States. The association between drive times and population density, income, ethnicity, race, and audiology program distance was evaluated with a population density-matched case-control study and multiple linear regression analyses.

RESULTS

Approximately 5.29 million Americans need to drive at least 1 hr to visit their closest audiologist. The 10% most rural-dwelling Americans drive an average of 33.8 min. The population density-matched case-control study demonstrated that percent below poverty, percent identifying as Hispanic, and travel times to the nearest audiology program were all significantly higher in census block groups with high drive times to the nearest audiologist. An average of 7.96% of individuals in census block groups with low drive times identified as Hispanic, but 18.8% identified as Hispanic in high drive time groups. The multiple linear regression showed that the effect of demographics and distance to the nearest audiology program was highest in rural areas. In both analyses, adjusting for poverty did not drastically change the effect of percent identifying as Hispanic on drive times.

CONCLUSIONS

Long drive times restrict access to audiological care for those who live in rural areas. This restriction disproportionately affects those in rural areas who identify as Hispanic or have low income.

Family Medicine Implementation to Maternal and Child Health in Rural Japan: A Narrative Review

This research provides a critical narrative review of maternal and child health (MCH) in rural Japan, reflecting broader challenges faced by aging societies globally. The study explores the intertwined roles of professional and lay care in sustaining rural communities, emphasizing the unique position of family medicine and primary care in enhancing MCH services. The scarcity of healthcare resources, particularly the shortage of obstetricians and the weakening of traditional community support systems, underscores the challenges in these areas. Our review method involved a comprehensive search of PubMed for articles published from April 2000 to August 2024, focusing on MCH issues in rural Japan. This study highlights several critical gaps in rural MCH provision: the migration of medical professionals to urban centers, the transformation of social structures affecting traditional caregiving, and the lack of specialized MCH training among primary care physicians. We discuss potential solutions such as incentivizing obstetric care in rural areas, integrating MCH education within family medicine curricula, and revitalizing community-based support systems. By addressing these issues, the research aims to formulate actionable strategies to bolster MCH services, thus ensuring better health outcomes and sustainability of rural communities in Japan and similar settings worldwide.

Reduction in all-cause medical and caregiving costs through innovative health awareness projects in a rural area in Japan: a retrospective cohort study

BACKGROUND

This study evaluates cost reduction in participants of a health awareness program (the Center of Healthy Aging Program, CHAP) in a Japanese rural area, characterized by an annual check-up and personalized interview on health issues and related risks immediately after the check-up.

METHODS

This is a cross-sectional study using medical and caregiving costs and Japan-specific health check-up results in Hirosaki residents stored by the local government, which were individually-based linked to the CHAP information collected by Hirosaki University. This is the first study that used anonymized data with individually-based linkages to both a research institute and a local government in Japan under a strict limitation regarding linking to third-party data. We included residents who had been continuously enrolled for > 6 months as of 1 July 2015. We compared 5-year all-cause costs between three groups (with CHAP, with Japan-specific health check-up, and no check-up) using a multivariate negative binomial regression model considering risk factors including lifestyle habits and an inverse probability weight to adjust for baseline characteristics: age, sex, Charlson comorbidity index, baseline care level, and risk score of coronary heart diseases.

RESULTS

A total of 384, 9805, and 32,630 residents aged 40-74 years were included for the CHAP, Japan-specific health check-up, and no check-up groups, respectively. The Japan-specific health check-up group showed older and higher Charlson comorbidity index than the others. After inverse probability weight adjusting, the amount of all-cause medical costs was significantly lower only in the CHAP group. Faster walking speed and exercise habits were independently associated with lower all-cause medical and caregiving costs.

CONCLUSIONS

We demonstrated a 5-year all-cause cost reduction in residents who participated in the CHAP and also suggested the effect of exercise habits in Hirosaki, which indicated the significance of individually-based data linkages to external third-party data for all local governments to improve the health condition of residents.

Cointegrations in house price dynamics and ageing population risks

How does the riskiness of an ageing population change with house price dynamics of rural areas? Why do rural house prices increase faster than cities despite their ageing populations? Life cycle theory predicts working age households have higher demand for housing than retirement households. An issue that has seen much less attention in the literature is that rural house prices have been increasing despite their populations age rapidly. To answer these issues, our paper introduces an empirical cointegration-based framework designed to be flexible for empirical settings. Our cointegration framework reveals crucial information about rural housing and ageing which has not been found previously: the short-term deviation of house prices from cointegration restrictions is a strong predictor of future rural house prices and migration rate from 1 to 4 year ahead. This is not the case for urban areas nor where cointegration restrictions are being ignored. Rural house prices, not urban ones, are the key to understand this cointegration restriction. Our framework is pertinent to most ageing societies with available housing and demographic data. When a government formulates macroprudential policies internalizing these cointegration restrictions and supporting rural developments, migration into rural areas and population increases are possible. Our evidence highlights the importance of cointegration-based long-run ageing risks for rural housing markets.

Adipo-oncology: adipocyte-derived factors govern engraftment, survival, and progression of metastatic cancers

Conventional therapies for metastatic cancers have limited efficacy. Recently, cancer therapies targeting noncancerous cells in tumor microenvironments have shown improved clinical outcomes in patients. However, further advances in our understanding of the metastatic tumor microenvironment are required to improve treatment outcomes. Adipocytes are distributed throughout the body, and as a part of the metastatic tumor microenvironment, they interact with cancer cells in almost all organs. Adipocytes secrete various factors that are reported to exert clinical effects on cancer progression, including engraftment, survival, and expansion at the metastatic sites. However, only a few studies have comprehensively examined their impact on cancer cells. In this review, we examined the impact of adipocytes on cancer by describing the adipocyte-secreted factors that are involved in controlling metastatic cancer, focusing on adipokines, such as adiponectin, leptin, visfatin, chemerin, resistin, apelin, and omentin. Adipocyte-secreted factors promote cancer metastasis and contribute to various biological functions of cancer cells, including migration, invasion, proliferation, immune evasion, and drug resistance at the metastatic sites. We propose the establishment and expansion of "adipo-oncology" as a research field to enhance the comprehensive understanding of the role of adipocytes in metastatic cancers and the development of more robust metastatic cancer treatments.
