Association of Habitual Green Tea Consumption with Sarcopenia Assessed Using SARC-F in Community-Dwelling Japanese Older People: A Cross-Sectional Study.

To ascertain whether habitual green tea consumption is associated with sarcopenia among Japanese older adults, using the screening tool for sarcopenia (SARC-F). This cross-sectional study in Mukawa, Hokkaido, Japan, was conducted between June and September 2022 and included 364 Japanese participants older than 65 y. Habitual green tea consumption and energy intake were ascertained using a validated self-administered food frequency questionnaire. Sarcopenia was evaluated using the SARC-F. Multivariable logistic regression analysis was used to estimate the odds ratio (OR) and 95% confidence interval (CI) of sarcopenia risk across participant tertiles of green tea consumption, with adjustments for age, sex, body mass index, living alone, habitual exercise, walking hours, current smoking status, current alcohol consumption status, energy intake, protein intake, vegetable intake, and fruit intake. In this study of 364 participants (154 men and 210 women), the prevalence of sarcopenia risk was 9.3%. The multivariable-adjusted OR [95% CI] of green tea consumption for ≥1 cup/d compared with that of <1 cup/wk of sarcopenia was 0.312 [0.129-0.752]. Higher habitual green tea consumption was inversely associated with sarcopenia among Japanese older adults. Further longitudinal studies are required to confirm these findings.

Burden of undiagnosed depression among older adults in India: a population based study.

BACKGROUND: The study explored the levels and associated factors of undiagnosed depression among community-dwelling older Indian adults. It also identified the socio-demographic predictors of undiagnosed depression among the study population at national and state levels. METHODS: The study employed data from the Longitudinal Ageing Study in India wave-I, 2017-18. Based on the data on depression from interviewee's self-reporting and measurement on Composite International Diagnostic Interview- Short Form (CIDI-SF) and Centre for Epidemiological Studies- Depression scale (CES-D) scales, we estimated undiagnosed depression among older adults (age 60+). We estimated multivariable binary logistic regressions to examine the socio-demographic and health-related predictors of undiagnosed depression among older adults. FINDINGS: 8% (95% CI: 7.8-8.4) of the total older adults had undiagnosed depression on CIDI-SF scale and 5% (95% CI: 4.8-5.3) on the combined CIDI-SF and CES-D. Undiagnosed depression was higher among those who were widowed, worked in the past and currently not working, scheduled castes, higher educated and the richest. Lack of health insurance coverage, presence of any other physical or mental impairment, family history of Alzheimer's/Parkinson's disease/ psychotic disorder, lower self-rated health and poor life satisfaction were significant predictors of undiagnosed depression on both CIDI-SF and combined scales. CONCLUSION: To improve the health of older adults in India, targeted policy efforts integrating mental health screening, awareness campaigns and decentralization of mental healthcare to primary level is needed. Further research could explore the causal factors behind different levels of undiagnosed depression.

Changes in social care after major emergency general surgery procedures.

BACKGROUND: Emergency general surgery (EGS) is a major part of the provision of healthcare, and patients undergoing EGS are at elevated risk of morbidity and mortality. This study aimed to determine factors contributing to patients losing their independence and being discharged to residential and nursing homes having previously lived in their own residences. METHODS: Our local data uploaded to the National Emergency Laparotomy Audit (NELA) (2014-2022) were analyzed. This national database encompasses all major EGS cases undertaken in the United Kingdom. The variables considered were patient demographics, American Society of Anesthesiologists score, admission and discharge dates, presenting pathology, operation type, and discharge destination. Comparative analyses segmented patients based on postdischarge EGS destinations. Multivariable logistic regression identified factors linked to residential/nursing home placement after discharge. Significance was set at P < .05. RESULTS: Data from all patients in the NELA database (n = 1611) were analyzed. Approximately 1 in 10 patients older than 70 years never returned home. Patients requiring additional support were on average 8.6 years older (P = .008). At older than 80 years, the need for extra social support increased substantially with each increasing year in age, and those older than 85 years were more than twice as likely to require extra support than 80-year-olds (P < .001). Patients who died were 11.4 years older than those discharged without additional support (P < .001). CONCLUSION: A significant proportion of patients, particularly the elderly, do not return to their usual place of residence and require a higher level of care postemergency surgery. These important social factors need to be considered before operating given that they may have significant quality of life and economic implications.

Risk Assessment and Prevention of Falls in Older Community-Dwelling Adults: A Review.

Importance: Falls are reported by more than 14 million US adults aged 65 years or older annually and can result in substantial morbidity, mortality, and health care expenditures. Observations: Falls result from age-related physiologic changes compounded by multiple intrinsic and extrinsic risk factors. Major modifiable risk factors among community-dwelling older adults include gait and balance disorders, orthostatic hypotension, sensory impairment, medications, and environmental hazards. Guidelines recommend that individuals who report a fall in the prior year, have concerns about falling, or have gait speed less than 0.8 to 1 m/s should receive fall prevention interventions. In a meta-analysis of 59 randomized clinical trials (RCTs) in average-risk to high-risk populations, exercise interventions to reduce falls were associated with 655 falls per 1000 patient-years in intervention groups vs 850 falls per 1000 patient-years in nonexercise control groups (rate ratio [RR] for falls, 0.77; 95% CI, 0.71-0.83; risk ratio for number of people who fall, 0.85; 95% CI, 0.81-0.89; risk difference, 7.2%; 95% CI, 5.2%-9.1%), with most trials assessing balance and functional exercises. In a meta-analysis of 43 RCTs of interventions that systematically assessed and addressed multiple risk factors among individuals at high risk, multifactorial interventions were associated with 1784 falls per 1000 patient-years in intervention groups vs 2317 falls per 1000 patient-years in control groups (RR, 0.77; 95% CI, 0.67-0.87) without a significant difference in the number of individuals who fell. Other interventions associated with decreased falls in meta-analysis of RCTs and quasi-randomized trials include surgery to remove cataracts (8 studies with 1834 patients; risk ratio [RR], 0.68; 95% CI, 0.48-0.96), multicomponent podiatry interventions (3 studies with 1358 patients; RR, 0.77; 95% CI, 0.61-0.99), and environmental modifications for individuals at high risk (12 studies with 5293 patients; RR, 0.74; 95% CI, 0.61-0.91). Meta-analysis of RCTs of programs to stop medications associated with falls have not found a significant reduction, although deprescribing is a component of many successful multifactorial interventions. Conclusions and Relevance: More than 25% of older adults fall each year, and falls are the leading cause of injury-related death in persons aged 65 years or older. Functional exercises to improve leg strength and balance are recommended for fall prevention in average-risk to high-risk populations. Multifactorial risk reduction based on a systematic clinical assessment for modifiable risk factors may reduce fall rates among those at high risk.

Life-Space Mobility: Normative Values From a National Cohort of U.S. Older Adults.

BACKGROUND: Life-space mobility, which measures the distance, frequency, and independence achieved as individuals move through their community, is one of the most important contributors to healthy aging. The University of Alabama at Birmingham Life-Space Assessment (LSA) is the most commonly used measure of life-space mobility in older adults, yet U.S. national norms for LSA have not previously been reported. This study reports such norms based on age and sex among community-dwelling older adults. METHODS: A cross-sectional analysis using data from the national REasons for Geographic and Racial Disparities in Stroke cohort study. LSA data were available for 10 118 Black and White participants over age 50, which were grouped by age (in 5-year increments) and sex, weighted for the U.S. national population. Correlations were calculated between LSA and measures of functional and cognitive impairment and physical performance. RESULTS: The weighted mean LSA ranged from 102.9 for 50-54-year-old males to 69.5 for males aged 85 and older, and from 102.1 for 50-54-year-old females to 60.1 for females aged 85 and older. LSA was strongly correlated with measures of timed walking, activities of daily living, cognition, depressive symptoms, and quality of life (all p < .001). CONCLUSIONS: We report U.S. national norms for LSA among community-dwelling Black and White older adults. These norms can serve as a reference tool for determining if clinical and research samples have greater or lesser life-space mobility than typical older adults in the United States for their age and sex.

Diet Quality and Multimorbidity in Older Adults: A Prospective Cohort Study.

BACKGROUND: The role of diet quality in the accumulation of multiple chronic conditions is mostly unknown. This study examined diet quality in association with the number of chronic conditions and the rate of multimorbidity development among community-dwelling older adults. METHODS: We used data from 2 784 adults aged ≥65 years from the Seniors-ENRICA 2 cohort. Diet quality was assessed at baseline (2015-17) with the Alternate Healthy Eating Index-2010 (AHEI-2010) and the Mediterranean Diet Adherence Screener (MEDAS). Information on medical diagnoses was obtained from electronic clinical records up to 2021. RESULTS: Higher adherence to the AHEI-2010 was associated with a lower number of total chronic conditions (ß [95% CI] quartile 4 vs 1: -0.57 [-0.86 to 0.27], p trend < .001] and cardiometabolic conditions (-0.30 [-0.44 to -0.17], p trend < .001) at baseline, while higher adherence to the MEDAS was associated with a lower number of total chronic conditions (-0.30 [-0.58 to -0.02], p trend = .01) and neuropsychiatric and neurodegenerative conditions (-0.09 [-0.17 to -0.01], p trend = .01). After a median follow-up of 5.2 years (range: 0.1-6.1 years) higher adherence to the AHEI-2010 was associated with a lower increase in chronic conditions (ß [95% confidence interval] quartile 4 vs 1: -0.16 [-0.30 to -0.01], p trend = .04) and with lower rate of chronic disease accumulation. CONCLUSIONS: Higher diet quality, as measured by the AHEI-2010, was associated with a lower number of chronic health conditions and a lower rate of multimorbidity development over time.

Serum vitamin D levels and mortality in Mexicans: results from the Mexican Health and Aging Study.

Introduction: Background: the population in Latin America is aging and elders face several obstacles for good health, including an elevated frequency of vitamin D deficiency. Thus, identification of patients at high risk to develop its negative consequences should be a priority. Objective: the objective of this analysis was to determine if levels of vitamin D lower than 15 ng/ml are associated with high mortality in Mexican elderly population, from the database of the Mexican Health and Aging Study (MHAS). Methods: prospective, population study in Mexico, that included Subjects of 50 years and older who were evaluated for Serum vitamin D levels during the year 2012 (third wave of the study). Serum 25(OH)D levels were categorized into four groups, based on cutoff points used in previous studies on vitamin D and frailty: < 15, 15-< 20, 20-< 30 and ≥ 30 ng/ml. Mortality was evaluated during 2015 (fourth wave of the study). Hazard ratio was calculated (for mortality) through Cox Regression Model, adjusted for covariates. Results: we included 1626 participants, and those with lower levels of vitamin D were older, more often women, required more aid for activities of daily living, reported higher number of chronic diseases, and lower scores on cognition. The relative risk of death was 5.421 (95 % CI 2.465-11.92, p < 0.001) for the participants with vitamin D levels < 15, which after adjusting for covariates, remained statistically significant. Conclusions: levels of vitamin D lower of 15, are associated with an increase in the rate of mortality in community-dwelling senior Mexicans.

Introducción: Introducción: la población en América Latina está envejeciendo y los adultos mayores enfrentan varios obstáculos para gozar de buena salud, incluida una frecuencia elevada de deficiencia de vitamina D. Por lo tanto, la identificación de pacientes con alto riesgo de desarrollar sus consecuencias negativas debe ser una prioridad. Objetivo: el objetivo de este análisis fue determinar si los niveles de vitamina D inferiores a 15 ng/ml están asociados con una alta mortalidad en la población adulta mayor mexicana, a partir de la base de datos del Estudio de Salud y Envejecimiento en México. Métodos: estudio poblacional prospectivo en México, que incluyó Sujetos de 50 años y mayores que fueron evaluados para los niveles de vitamina D en suero durante el año 2012 (tercera ola del estudio). Los niveles séricos de 25(OH)D se clasificaron en cuatro grupos, según los puntos de corte utilizados en estudios previos sobre vitamina D y fragilidad: < 15, 15-< 20, 20-< 30 y ≥ 30 ng/ml. La mortalidad se evaluó durante 2015 (cuarta ola del estudio). Se calculó la razón de riesgo (para la mortalidad) a través del modelo de regresión de Cox, ajustado por covariables. Resultados: incluimos 1626 participantes, y aquellos con niveles más bajos de vitamina D eran mayores, más a menudo mujeres, requerían más ayuda para las actividades de la vida diaria, informaron un mayor número de enfermedades crónicas y puntuaciones más bajas en cognición. El riesgo relativo de muerte fue de 5,421 (IC 95 % 2,465-11,92, p < 0,001) para los participantes con niveles de vitamina D < 15, que después de ajustar por covariables, se mantuvo estadísticamente significativo. Conclusiones: niveles de vitamina D inferiores a 15, se asocian con un aumento en la tasa de mortalidad en adultos mayores mexicanos residentes en la comunidad.

Domains of Frailty Predict Loss of Independence in Older Adults After Noncardiac Surgery.

IMPORTANCE: Preoperative frailty has been consistently associated with death, severe complications, and loss of independence (LOI) after surgery. LOI is an important patient-centered outcome, but it is unclear which domains of frailty are most strongly associated with LOI. Such information would be important to target individual geriatric domains for optimization. OBJECTIVE: To assess whether impairment in individual domains of the Edmonton Frail Scale (EFS) can predict LOI in older adults after noncardiac surgery. DESIGN: Retrospective Cohort Study. SETTING: One Academic Hospital. PARTICIPANTS: Patients aged 65 or older who were living independently and evaluated with the EFS during a preoperative visit to the Center for Preoperative Optimization at the Johns Hopkins Hospital between June 2018 and January 2020. MAIN OUTCOME: LOI defined as discharge to increased level of care outside of the home with new mobility deficit or functional dependence. New mobility deficit and functional dependence were extracted from chart review of the standardized occupational therapy and physical therapy assessment performed before discharge. RESULTS: A total of 3497 patients were analyzed. Age (mean±SD) was 73.4±6.2 years, and 1579 (45.2%) were female. The median total EFS score was 3 (range 0-16), and 725/3497 (27%) were considered frail (EFS≥6). The frequencies of impairment in each EFS domain were functional performance (33.5% moderately impaired, 11% severely impaired), history of hospital readmission (42%), poor self-described health status (37%), and abnormal cognition (17.1% moderately impaired, 13.8% severely impaired). Overall, 235/3497 (6.7%) patients experienced LOI. Total EFS score was associated with LOI (odds ratio: 1.37, 95% CI, 1.30-1.45, P <0.001) in a model adjusted for age, sex, body mass index, American Society of Anesthesiologists rating, congestive heart failure, valvular heart disease, hypertension diagnosis, chronic lung disease, diabetes, renal failure, liver disease, weight loss, anemia, and depression. Using a nested log likelihood approach, the domains of functional performance, functional dependence, social support, health status, and urinary incontinence improved the base multivariable model. In cross-validation, total EFS improved the prediction of LOI with the final model achieving an area under the curve of 0.840. Functional performance was the single domain that most improved outcome prediction, but together with functional dependence, social support, and urinary incontinence, the model resulted in an area under the curve of 0.838. CONCLUSION AND RELEVANCE: Among domains measured by the EFS before a wide range of noncardiac surgeries in older adults, functional performance, functional dependence, social support, and urinary incontinence were independently associated with and improved the prediction of LOI. Clinical initiatives to mitigate LOI may consider screening with the EFS and targeting abnormalities within these domains.

Evidence that dog ownership protects against the onset of disability in an older community-dwelling Japanese population.

OBJECTIVES: This study examined the association between dog and cat ownership, the onset of disability and all-cause mortality in an older population. Dog and cat owners take more regular exercise and have closer social relationships than non-owners. We further assess the beneficial effects of these moderating variables on the onset of disability and mortality. METHODS: Dog and cat ownership data were collected from 11233 community-dwelling adults age 65 years and older. These data were matched with data about the onset of disability held by the Japanese long-term care insurance system. Local registry data were used to ascertain all-cause mortality. RESULTS: During the approximately 3.5 year follow-up period, 17.1% of the sample suffered onset of disability, and 5.2% died. Logistic regression analysis indicated that, compared with a reference group of those who had never owned a dog (odds ratio fixed at 1.0), older adults who were currently dog owners had a significantly lower odds ratio of onset of disability (OR = 0.54 95% CI: 0.37-0.79). Our results further show that regular exercise interacts with dog ownership to reduce the risk of disability. The association of dog and/or cat ownership with all-cause mortality was not statistically significant. CONCLUSIONS: Dog ownership appears to protect against incident disability among older Japanese adults. Additional benefits are gained from ownership combined with regular exercise. Daily dog care may have an important role to play in health promotion and successful aging.

Associations of breastfeeding history with metabolic syndrome and cardiovascular risk factors in community-dwelling parous women: The Japan Multi-Institutional Collaborative Cohort Study.

OBJECTIVE: The aim of the present study was to investigate the associations between breastfeeding and the prevalence of metabolic syndrome in community-dwelling parous women and to clarify whether the associations depend on age. METHODS: The present cross-sectional study included 11,118 women, aged 35-69 years. Participants' longest breastfeeding duration for one child and their number of breastfed children were assessed using a self-administered questionnaire, and their total breastfeeding duration was approximated as a product of the number of breastfed children and the longest breastfeeding duration. The longest and the total breastfeeding durations were categorized into none and tertiles above 0 months. Metabolic syndrome and cardiovascular risk factors (obesity, hypertension, dyslipidemia, and hyperglycemia) were defined as primary and secondary outcomes, respectively. Associations between breastfeeding history and metabolic syndrome or each cardiovascular risk factor were assessed using multivariable unconditional logistic regression analysis. RESULTS: Among a total of 11,118 women, 10,432 (93.8%) had ever breastfed, and 1,236 (11.1%) had metabolic syndrome. In participants aged <55 years, an inverse dose-response relationship was found between the number of breastfed children and the prevalence of metabolic syndrome; multivariable-adjusted odds ratios for 1, 2, 3, and ≥4 breastfed children were 0.60 (95% confidence interval [CI]: 0.31 to 1.17), 0.50 (95% CI: 0.29 to 0.87), 0.44 (95% CI: 0.24 to 0.84), and 0.35 (95% CI: 0.14 to 0.89), respectively. The longest and total breastfeeding durations of longer than 0 months were also associated with lower odds of metabolic syndrome relative to no breastfeeding history in participants aged <55 years. In contrast, all measures of breastfeeding history were not significantly associated with metabolic syndrome and cardiovascular risk factors in participants aged ≥55 years old. CONCLUSIONS: Breastfeeding history may be related to lower prevalence of metabolic syndrome in middle-aged parous women.

Association of material deprivation with discharge location and length of stay after inpatient stroke rehabilitation in Ontario: a retrospective, population-based cohort study.

BACKGROUND: Low socioeconomic status is associated with increased risk of stroke and worse poststroke functional status. The aim of this study was to determine whether socioeconomic status, as measured by material deprivation, is associated with direct discharge to long-term care or length of stay after inpatient stroke rehabilitation. METHODS: We performed a retrospective, population-based cohort study of people admitted to inpatient rehabilitation in Ontario, Canada, after stroke. Community-dwelling adults (aged 19-100 yr) discharged from acute care with a most responsible diagnosis of stroke between Sept. 1, 2012, and Aug. 31, 2017, and subsequently admitted to an inpatient rehabilitation bed were included. We used a multivariable logistic regression model to examine the association between material deprivation quintile (from the Ontario Marginalization Index) and discharge to long-term care, and a multivariable negative binomial regression model to examine the association between material deprivation quintile and rehabilitation length of stay. RESULTS: A total of 18 736 people were included. There was no association between material deprivation and direct discharge to long-term care (most v. least deprived: odds ratio [OR] 1.07, 95% confidence interval [CI] 0.89-1.28); however, people living in the most deprived areas had a mean length of stay 1.7 days longer than that of people in the least deprived areas (p = 0.004). This difference was not significant after adjustment for other baseline differences (relative change in mean 1.02, 95% CI 0.99-1.04). INTERPRETATION: People admitted to inpatient stroke rehabilitation in Ontario had similar discharge destinations and lengths of stay regardless of their socioeconomic status. In future studies, investigators should consider further examining the associations of material deprivation with upstream factors as well as potential mitigation strategies.

Trends in the Use of Residential Settings Among Older Adults.

OBJECTIVES: As the U.S. population ages, the prevalence of disability and functional limitations, and demand for long-term services and supports (LTSS), will increase. This study identified the distribution of older adults across different residential settings, and how their health characteristics have changed over time. METHODS: A cross-sectional analysis of older adults residing in traditional housing, community-based residential facilities (CBRFs), and nursing facilities using 3 data sources: the Medicare Current Beneficiary Survey (MCBS), 2008 and 2013; the Health and Retirement Study (HRS), 2008 and 2014; and the National Health and Aging Trends Study, 2011 and 2015. We calculated the age-standardized prevalence of older adults by setting, functional limitations, and comorbidities and tested for health characteristics changes relative to the baseline year (2002). RESULTS: The proportion of older adults in traditional housing increased over time, relative to baseline (p < .05), while the proportion of older adults in CBRFs was unchanged. The proportion of nursing facility residents declined from 2002 to 2013 in the MCBS (p < .05). The prevalence of dementia and functional limitations among traditional housing residents increased, relative to the baseline year in the HRS and MCBS (p < .05). DISCUSSION: The proportion of older adults residing in traditional housing is increasing, while the nursing facility population is decreasing. This change may not be due to better health; rather, older adults may be relying on noninstitutional LTSS.

Homebound status among older adult home care recipients in Ontario, Canada.

BACKGROUND: Homebound status is associated with an increased risk of morbidity and mortality in older adults, yet little is known about homebound older adults in Canada. Our objectives were to describe time trends in the prevalence of homebound status among community-dwelling long-term home care recipients and the characteristics associated with homebound status. METHODS: This was a retrospective cross-sectional and cohort study using linked health administrative data in Canada's most populous province, Ontario. We included adults aged 65 years and older who received at least one long-term home care assessment from 2006 to 2017 (N = 666,514). Homebound individuals were those who exited the home an average of 0-1 days/week over the previous 30 days; not homebound comparators exited the home 2-7 days per week. We compared baseline characteristics between groups and estimated the association between these characteristics and homebound status at baseline and over time. RESULTS: From 2006 to 2017, the annual proportion of long-term home care recipients who were homebound increased from 48% to 65%. At first assessment, 50% of the cohort (331,836 of 666,514) were homebound. Among those with a 4-12 month repeat assessment, homebound status persisted over time for 80%, and developed anew in 24%. Dependency on others for locomotion, use of an assistive device, poor access to dwelling, older age, and female sex were most strongly associated with homebound status at baseline, as well as its development and persistence over time. CONCLUSIONS: We found that half of Ontario older adult long-stay home care clients were homebound at the time of their first assessment, and that the prevalence of homebound status among home care recipients rose steadily from 2006 to 2017. This informs further research and policy development to ensure the adequacy of supports for older homebound persons.

Understanding the role of informal caregivers in postoperative care transitions for older patients.

BACKGROUND: Older adults may have new care needs and functional limitations after surgery. Many rely on informal caregivers (unpaid family or friends) after discharge but the extent of informal support is unknown. We sought to examine the role of informal postoperative caregiving on transitions of care for older adults undergoing routine surgical procedures. MATERIALS AND METHODS: We performed a retrospective cohort study using ACS NSQIP Geriatric Pilot Project data, 2014-2018. Patients were ≥65 years and underwent an inpatient surgical procedure. Patients who lived at home alone were compared with those who lived with support from informal caregivers (family and/or friends). Primary outcomes were discharge destination (home vs. post-acute care) and readmission within 30 days. Multivariable logistic regression was used to determine the association between support at home, discharge destination, and readmission. RESULTS: Of 18,494 patients, 25% lived alone before surgery. There was no difference in loss of independence (decline in functional status or new use of mobility aid) after surgery between patients who lived alone or with others (18.7% vs. 19.5%, p = 0.24). Nevertheless, twice as many patients who lived alone were discharged to a non-home location (10.2% vs. 5.1%; OR: 2.24, CI: 1.93-2.56). Patients who lived alone and were discharged home with new informal caregivers had increased odds of readmission (OR: 1.43, CI: 1.09-1.86). CONCLUSION: Living alone independently predicts discharge to post-acute care, and patients who received new informal caregiver support at home have higher odds of readmission. These findings highlight opportunities to improve discharge planning and care.

Change in central nervous system-active medication use following fall-related injury in older adults.

BACKGROUND: Central nervous system (CNS)-active medication use is an important modifiable risk factor for falls in older adults. A fall-related injury should prompt providers to evaluate and reduce CNS-active medications to prevent recurrent falls. We evaluated change in CNS-active medications up to 12 months following a fall-related injury in community-dwelling older adults compared with a matched cohort without fall-related injury. METHODS: Participants were from the Adult Changes in Thought study conducted at Kaiser Permanente Washington. Fall-related injury codes between 1994 and 2014 defined index encounters in participants with no evidence of such injuries in the preceding year. We matched each fall-related injury index encounter with up to five randomly selected clinical encounters from participants without injury. Using automated pharmacy data, we estimated the average change in CNS-active medication use at 3, 6, and 12 months post-index according to the presence or absence of CNS-active medication use before index. RESULTS: One thousand five hundred sixteen participants with fall-related injury index encounters (449 CNS-active users, 1067 nonusers) were matched to 7014 index encounters from people without fall-related injuries (1751 users, 5236 nonusers). Among CNS-active users at the index encounter, those with fall-related injury had an average decrease in standard daily doses (SDDs) at 12 months (-0.43; 95% CI: -0.63 to -0.23), and those without injury had a greater (p = 0.047) average decrease (-0.66; 95% CI: -0.78 to -0.55). Among nonusers at index, those with fall-related injury had a smaller increase than those without injury (+0.17, 95% CI: +0.13 to +0.21, vs. +0.24, 95% CI: +0.20 to +0.28, p = 0.005). CONCLUSIONS: The differences in CNS-active medication use change over 12 months between those with and without fall-related injury were small and unlikely to be clinically significant. These results suggest that fall risk-increasing drug use is not reduced following a fall-related injury, thus opportunities exist to reduce CNS-active medications, a potentially modifiable risk factor for falls.

A proinflammatory diet is associated with increased odds of frailty after 12-year follow-up in a cohort of adults.

BACKGROUND: Frailty occurs in 10-15% of community-living older adults and inflammation is a key determinant of frailty. Though diet is a modulator of inflammation, there are few prospective studies elucidating the role of diet-associated inflammation on frailty onset. OBJECTIVES: We sought to determine whether a proinflammatory diet was associated with increased odds of frailty in adults from the Framingham Heart Study (FHS). DESIGN AND METHODS: This study was nested in a prospective cohort that included individuals without frailty. Diet was assessed in 1998-2001 using a valid FFQ, and frailty was measured in 2011-2014. FFQ-derived energy-adjusted dietary inflammatory index (E-DII®) scores were computed, with higher E-DII scores indicating a more proinflammatory diet. Frailty was defined as fulfilling ≥3 of 5 Fried Phenotype criteria. Information on potential mediators, serum IL-6 and C-reactive protein was obtained in 1998-2001. Logistic regression estimated ORs and 95% CIs for E-DII (as continuous and in quartiles) and frailty onset adjusting for relevant confounders. RESULTS: Of 1701 individuals without frailty at baseline (mean ± SD age: 58 ± 8 y; range: 33-81 y; 55% female), 224 developed frailty (13% incidence) over ∼12 y. The mean ± SD E-DII score was -1.95 ± 2.20; range: -6.71 to +5.40. After adjusting for relevant confounders, a 1-unit higher E-DII score was associated with 16% increased odds of developing frailty (95% CI: 1.07, 1.25). In categorical analyses, participants in the highest (proinflammatory) compared with lowest quartile of E-DII had >2-fold increased odds of frailty (ORquartile4vs.1: 2.22; 95% CI: 1.37, 3.60; P-trend < 0.01). IL-6 and C-reactive protein were not major contributors in the pathway. CONCLUSIONS: In this cohort of middle-aged and older adults, a proinflammatory diet was associated with increased odds of frailty over ∼12 y of follow-up. Trials designed to increase consumption of anti-inflammatory foods for frailty prevention are warranted.

Metabolic syndrome is not associated to an increased risk of low bone mineral density in men at risk for osteoporosis.

PURPOSE: We have recently demonstrated a significant association between osteoporosis (Op) and metabolic syndrome (MetS) in Caucasian women examined by Dual-energy X-ray absorptiometry (DXA) for suspected Op. This cross-sectional study was performed to evaluate the association between MetS and Op in Caucasian men enrolled in the same geographical area, with identical criteria and in the same time range. METHODS: Among subjects enrolled in the SIMON study, we selected the medical records of all free-living men who performed a contextual evaluation of both bone mineral density (BMD) by DXA and MetS constitutive elements (arterial blood pressure, waist circumference, serum levels of triglycerides, high-density lipoprotein cholesterol, and fasting glucose). All enrolled subjects refer to "COMEGEN" general practitioners' cooperative operating in Naples, Southern Italy. RESULTS: Overall, the medical records of 880 men were examined. No significant association between MetS and Op was observed. Among MetS constitutive elements, waist circumference was inversely related to Op risk. CONCLUSION: In Caucasian men examined by DXA for suspected Op, no significant association was observed between Op and MetS. The study results contrast to those observed in women enrolled in the same geographical area, with identical criteria and in the same time range and may be related to sexual dimorphism occurring in clinical expressiveness of both MetS and Op.

Association of Social Support With Functional Outcomes in Older Adults Who Live Alone.

Importance: Older adults who live alone are at risk for poor health outcomes. Whether social support mitigates the risk of living alone, particularly when facing a sudden change in health, has not been adequately reported. Objective: To assess if identifiable support buffers the vulnerability of a health shock while living alone. Design, Setting, and Participants: In this longitudinal, prospective, nationally representative cohort study from the Health and Retirement Study (enrollment March 2006 to April 2015), 4772 community-dwelling older adults 65 years or older who lived alone in the community and could complete activities of daily living (ADLs) and instrumental ADLs independently were followed up biennially through April 2018. Statistical analysis was completed from May 2020 to March 2021. Exposures: Identifiable support (ie, can the participant identify a relative/friend who could help with personal care if needed), health shock (ie, hospitalization, new diagnosis of cancer, stroke, heart attack), and interaction (multiplicative and additive) between the 2 exposures. Main Outcomes and Measures: The primary outcomes were incident ADL dependency, prolonged nursing home stay (≥30 days), and death. Results: Of 4772 older adults (median [IQR] age, 73 [68-81] years; 3398 [71%] women) who lived alone, at baseline, 1813 (38%) could not identify support, and 3013 (63%) experienced a health shock during the study. Support was associated with a lower risk of a prolonged nursing home stay at 2 years (predicted probability, 6.7% vs 5.2%; P = .002). Absent a health shock, support was not associated with a prolonged nursing home stay (predicted probability over 2 years, 1.9% vs 1.4%; P = .21). However, in the presence of a health shock, support was associated with a lower risk of a prolonged nursing home stay (predicted probability over 2 years, 14.2% vs 10.9%; P = .002). Support was not associated with incident ADL dependence or death. Conclusions and Relevance: In this longitudinal cohort study among older adults who live alone, identifiable support was associated with a lower risk of a prolonged nursing home stay in the setting of a health shock.

Leveraging survey and claims data to identify high-need Medicare beneficiaries in the National Health and Aging Trends Study.

BACKGROUND: Multiple algorithms have been developed to identify and characterize the high-need (HN) Medicare population. However, they vary in components and yield different populations, and were developed for varying purposes. We compared the performance of existing survey and claims-based definitions in identifying HN beneficiaries and predicting poor outcomes among a community-dwelling population. METHODS: A retrospective cohort study using Round 5 (2015) of the National Health and Aging Trends Study (NHATS) linked with Medicare claims. We applied HN definitions from previous studies to our cohort of community-dwelling, fee-for-service beneficiaries (n = 4201) using sampling weights to obtain nationally representative estimates. The Bélanger et al. (2019) definition defines HN as individuals with complex conditions, multi-morbidity, acute and post-acute healthcare utilization, dependency in activities of daily living, and frailty. The Hayes et al. (2016) definition defines HN as individuals with 3+ chronic conditions and a functional limitation. We applied each definition to survey and claims data. Outcomes were hospitalization or mortality in the subsequent year. RESULTS: The proportion of NHATS respondents classified as HN varied greatly across definitions, ranging from 3.1% using the claims-based Hayes definition to 32.9% using the survey-based Bélanger definition. HN respondents had significantly higher mortality and hospitalization rates in 2016. Although all definitions had good specificity, none were able to predict outcomes in the following year with good accuracy. CONCLUSIONS: While mortality and hospitalization rates were significantly higher among respondents classified as HN, existing claims and survey-based HN definitions were not able to accurately predict future outcomes in a community-dwelling, nationally representative sample measured by the area under the curve.
