Abstract
Objective: We investigated cross-sectional and longitudinal associations of diet quality with middle-aged caregiver status. Methods: Caregiving in the Healthy Aging in Neighborhoods of Diversity across the Life Span (HANDLS) study (57.7% women, 62% African American (AA)) was measured at waves 3 (2009–2013) and 4 (2013–2017) (mean follow-up time 4.1 years). Diet quality was assessed by the Healthy Eating Index 2010 (HEI-2010) derived from two separate 24 h diet recalls. Multivariable ordinary least square regression was performed for cross-sectional analyses of the association of wave 4 caregiving with wave 4 HEI-2010. Wave 3 caregiving was examined both cross-sectionally and with annual rate of change in HEI using mixed-effects linear regression Models. Multivariable models were adjusted for age, sex, and poverty status. Results: Cross-sectional analyses at wave 4 demonstrate an inverse association of frequent caregiving (“Daily or Weekly” vs. “Never”) for grandchildren with HEI-2010 total score (i.e., lower diet quality) among Whites (β = −2.83 ± 1.19, p = 0.03, Model 2) and AAs (β = −1.84 ± 0.79, p = 0.02,). The “cross-sectional” analysis pertaining to grandchildren caregiving frequency suggested that frequent caregiving (i.e., “Daily or Weekly” vs. “Never” (β = −2.90 ± 1.17, p = 0.04)) only among Whites was inversely related to HEI-2010 total score. Total HEI-2010 score was also related to caring (Model 1), for the elderly over “5 years vs. Never” among Whites (−7.31 ± 3.54, p = 0.04, Model 2). Longitudinally, we found slight potential improvement in diet quality over time (“Daily or Weekly” vs. Never by TIME interaction: +0.88 ± 0.38, p = 0.02) with frequent caregiving among Whites, but not so among AAs. Conclusions: Frequent caring for grandchildren had an inverse relationship with the diet quality of White and AA urban middle-aged caregivers, while caring for elderly was inversely linked to diet quality among Whites only. Longitudinal studies should address the paucity of research on caregivers’ nutritional quality.

Abstract
Poor diet quality (DQ) is associated with poor cognition and increased neurodegeneration, including Alzheimer's disease (AD). We are interested in the role of DQ on cognitive functioning (by sex and increasing genetic risk for AD), in a sample of African American (AA) middle-aged adults. We analysed a sub-group of participants (about 55 % women; mean follow-up time of about 4·7 years) from the Healthy Aging in Neighborhoods of Diversity across the Life Span study with a genetic risk score for AD (hAlzScore). The Healthy Eating Index-2010, Dietary Approaches to Stop Hypertension and the mean adequacy ratio computed at baseline (2004-2009) and follow-up visits (2009-2013) were used to assess initial DQ and change over time. Linear mixed-effects regression models were utilised, adjusting for select covariates, selection bias and multiple testing. DQ change (ΔDQ) was associated with California Verbal Learning Test-List A - overall (0·15 (se 0·06), P = 0·008) and in women (0·21 (se 0·08), P = 0·006), at highest AD risk, indicating protective effects over time. Greater AD risk was longitudinally associated with poorer Clock Command Test scores in men. Poor DQ was positively and cross-sectionally associated with Trails B scores, but in women only. Better-quality diet was associated with a slower decline in verbal memory among AA women, with greater AD risk. Insufficient clinical evidence and/or mixed findings dictate that more studies are needed to investigate brain morphology and volume changes in relation to DQ in an at-risk population for AD, over time.

Health economic benefits from optimized meal services to older adults-a literature-based synthesis. Eur J Clin Nutr 2020; 75:26-37. [PMID: 32801305 DOI: 10.1038/s41430-020-00700-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/12/2019] [Revised: 06/19/2020] [Accepted: 08/04/2020] [Indexed: 11/08/2022]
Abstract
Malnutrition among older adults causes health problems and economic costs. Prevention of malnutrition through meal service can reduce such costs. This study estimates potential health economic benefits to be generated through meal service to home-dwelling older adults. The study contains three components: (1) systems analysis describing the relationship between meal service, nutritional status, health risk, and health-related costs, focusing on older adults, (2) a series of literature reviews to quantify the identified elements in each stage-subject combination: (i) meal service impact on nutrition status of older adults, (ii) associations between nutrition status and health risks, (iii) health care resource needs associated with these health risks, and (3) a model synthesis of literature findings to estimate the expected economic benefit of improved health status derived from meal service enrollment, using Denmark as an example. Expected economic benefits in terms of saved direct and indirect health care costs and improved quality-of-life was estimated at an amount of €307 per year per individual enrolled, of which direct health care cost savings constituted €75, while value of improved quality-of-life and reduced mortality constituted the rest. The average health economic benefit from enrolling older adults into meal service is likely to decrease with the number of subscribers. Findings like these are important to take into consideration, when making policy decisions regarding size of the meal service capacity, although it should be noted that the presented estimates are based on a number of assumptions of which some are subject to uncertainty.

The Interplay of Diet Quality and Alzheimer's Disease Genetic Risk Score in Relation to Cognitive Performance Among Urban African Americans. Nutrients 2019; 11:nu11092181. [PMID: 31514322 PMCID: PMC6769979 DOI: 10.3390/nu11092181] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/26/2019] [Revised: 09/06/2019] [Accepted: 09/08/2019] [Indexed: 12/23/2022] Open
Abstract
We examined the interactive associations of poor diet quality and Alzheimer’s Disease (AD) genetic risk with cognitive performance among 304 African American adults (mean age~57 years) from the Healthy Aging in Neighborhoods of Diversity across the Life Span (HANDLS) study. In this cross-sectional study, selected participants had complete predictors and covariate data with 13 cognitive test scores as outcomes. Healthy Eating Index-2010 (HEI-2010), Dietary Approaches to Stop Hypertension (DASH), and mean adequacy ratio (MAR) were measured. A genetic risk score for AD in HANDLS (hAlzScore) was computed from 12 selected single nucleotide polymorphisms (SNPs). Our key hypotheses were tested using linear regression models. The hAlzScore was directly associated with poor performance in verbal memory (−0.4 ± 0.2, 0.01) and immediate visual memory (0.4 ± 0.2, 0.03) measured in seconds, in women only. The hAlzScore interacted synergistically with poorer diet quality to determine lower cognitive performance on a test of verbal fluency. Among numerous SNP × diet quality interactions for models of cognitive performance as outcomes, only one passed correction for multiple testing, namely verbal fluency. Our results suggest that improved diet quality can potentially modify performance on cognitive tests of verbal fluency among individuals with higher AD genetic risk.

Abstract
It is the position of the American Dietetic Association that older Americans receive appropriate care; have broadened access to coordinated, comprehensive food and nutrition services; and receive the benefits of ongoing research to identify the most effective food and nutrition programs, interventions, and therapies across the spectrum of aging. Food and water and nutritional well-being are essential to the health, self-sufficiency, and quality of life for the fast growing, heterogeneous, multiracial, and ethnic populations of older adults. Many people, as they age, remain fully independent and actively engaged in their communities; however, others fare less well and need more support. A broad array of appropriate, culturally sensitive food and nutrition services, physical activities, and health and supportive care customized to the population of older adults are necessary. National, state, and local policies that promote coordination and integration of food and nutrition services into health and supportive systems are needed to maintain independence, functional ability, chronic disease management, and quality of life. Dietetics professionals can take the lead by researching and developing national, state, and local collaborative networks to incorporate effectively the food and nutrition services across the spectrum of aging.

Abstract
OBJECTIVE The number of remaining teeth may indicate the extent of life-long exposure to inflammation, a known risk factor for muscle loss and consequent disability. The aim was to study dental health status as a risk factor for muscle strength loss in very old people. DESIGN Cross-sectional and prospective cohort study over a 5-year follow-up. SETTING Research laboratory. PARTICIPANTS One hundred and ninety-three 80-year-old people participated in the baseline examinations. Five years later, 79 survivors were retested. MAIN OUTCOME MEASURES Number of remaining teeth, presence of periodontitis and handgrip strength. RESULTS At baseline, grip strength of men correlated positively with number of teeth but not with the presence of periodontitis. In women, the cross-sectional associations were not statistically significant. In the prospective analyses, the presence of periodontitis at baseline showed a clear association with a steeper decline in handgrip over the 5-year follow-up in both sexes. The values adjusted for gender, height, weight, number of chronic conditions and physical activity were -28.3% (SE 5.7) among those with periodontitis vs. -11.9% (SE 3.1, p = 0.015) among those with healthy gingiva. No association between the number of teeth at baseline and change in grip strength over 5 years was observed. CONCLUSIONS The presence of oral inflammation may lead to loss in muscle strength increasing the risk of disability. Therefore, good dental care throughout the life span may decrease risk of disability in old age.

Abstract
PURPOSE To evaluate whether cognitive impairment improves in elderly patients who have cataract surgery with intraocular lens (IOL) implantation. SETTING Kouki Hospital, Yamaguchi, Japan. METHODS A prospective observational study evaluated patients' scores on the Revised Hasegawa Dementia Scale (HDS-R) and the HDS-R minus 1 item regarding immediate regeneration (ie, function of vision and memory). Twenty patients (6 men, 14 women) with cognitive impairment had cataract surgery in 1 eye between March 1996 and July 2001 at Kouki Hospital, Japan. The mean age of the patients was 81.8 years (range 61 to 90 years). Twenty patients (4 men, 16 women) with cognitive impairment who did not have cataract surgery were selected as a control. The mean age in the control group was 84.3 years (range 70 to 93 years). The HDS-R was administered twice between March 1996 and July 2001. RESULTS The mean HDS-R scores in the cataract surgery group improved from 12.5 points +/- 5.3 (SD) preoperatively to 16.6 +/- 6.2 points postoperatively; the improvement was significant (t = -5.02; P<.0001). After cataract surgery, the grade of cognitive impairment improved in 12 patients (60%), was unchanged in 7 (35%), and was worse in 1 (5%). CONCLUSION Cataract surgery improved cognitive impairment in elderly Japanese patients.
