Improving nutrition to support healthy ageing: what are the opportunities for intervention?

Describing Community-Based Nurses' Knowledge, Attitudes, and Practices in the Nutritional Care of Older Adults: Results of a UK Survey

PURPOSE

To ascertain current nutritional knowledge and training needs of community-based nurses caring for older adults in the United Kingdom.

METHOD

A descriptive cross-sectional, anonymized, online survey of nurses' knowledge, attitudes, and practices related to older adults' nutrition was developed. Community-based nurses working with older adults in the United Kingdom were recruited via social media and convenience sampling.

RESULTS

Responses were received from 194 community-based nurses. Nutritional care was seen as a multidisciplinary responsibility by 62% of participants. Most undertook nutrition screening (93%), were confident in providing nutritional advice (83%), and ease of identifying those in need (88%) was high. However, some aspects of nutritional knowledge were less complete, including recommended daily intakes of protein (60% unsure) and fiber (52% unsure).

CONCLUSION

High confidence in delivering nutritional advice contrasted with uncertainty around some aspects of nutritional knowledge, suggesting opportunities to improve training on the nutritional needs of older adults. [Journal of Gerontological Nursing, 50(11), 13-19.].

Health Status of People Who Are and Are Not Experiencing Homelessness: Opportunities for Improvement

This study assessed the physical and psychological health parameters of adults experiencing homelessness to inform the development and delivery of health services by comparing with a housed population in the same South Australian city. Adults experiencing homelessness, known to existing support services, were invited to participate in a comprehensive assessment of their physical and mental health using questionnaires and objective assessments. Descriptive analyses using the percentage of participants failing to attain recommended published thresholds and accumulated health deficits for 16 health assessments were compared for the young group of people experiencing homelessness (18-40 years), the middle aged and older people experiencing homelessness (40-75 years), and a housed population of the middle aged and older people (40-75 years). Those experiencing homelessness had multiple and potentially inter-related health deficits compared with a population of people not experiencing homelessness in the same city. They were significantly less likely to meet healthy population norms for clinical frailty (p < 0.001), psychological distress (p < 0.001), grip strength (p < 0.001), lung function (p < 0.001), sleep quality (p < 0.001), and pelvic floor bother (p = 0.002). Significantly more accumulated health deficits were found for people experiencing homelessness when compared with the same ages for those who were not (mean 6.5 (SD 2.4) compared with 5.0 (SD 2.1)). This considerably increased for people experiencing homelessness aged less than 40 years (mean 8.7 (1.7)). Priorities for health service provision for people of different ages experiencing homelessness, when compared with housed community dwellers, have been described. The provision of targeted health assessments and service provision that specifically address healthcare needs among people experiencing homelessness are likely to have the biggest impacts across multiple health domains.

Body Mass Index as a Determinant of Lower Limb Function and Community Well-Being in Older Adults: Analysis of 2020 National Older Korean Survey Data

This epidemiological research investigated the relationship between body mass index (BMI) and lower limb function and community well-being among the older population (≥65 years old) in South Korea. Using the 2020 National Survey of Older Koreans (N = 10 097; Mage = 73.6 ± 6.63; MBMI = 23.6 ± 2.61), the study identified underweight (2.3%), normal (72.8%), and obese (24.9%) groups. Findings revealed significant associations between BMI and lower limb function, with underweight individuals facing greater physical challenges (P < .05-.01). Underweight participants were also found to live farther from key community locations, possibly reflecting social and environmental factors (P < .01) and expressed higher dissatisfaction with community environments (Ps < .05-.01). The study emphasizes the need for tailored community planning and health care strategies, focusing on the unique needs of the underweight older adults, considering South Korea's rapidly increasing older population.

Empirical analysis of health-related behaviors among older Hakka adults: a latent class analysis

Background

Little is known about health-related behaviors of the older Hakka population in China. We aimed to explore the characteristics and correlates of health-related behaviors among older Hakka adults.

Methods

We used data from the China's Health-Related Quality of Life Survey for Older Adults 2018. Latent class analysis (LCA) defined latent classes of health-related behaviors for 1,262 older Hakka adults aged 60 and above. Generalized linear regression and multinomial logistic regression analysis were used to identify factors influencing the number and the latent classes of health-related behaviors, respectively.

Results

The LCA showed that the latent classes could be stratified as the risk group (14.82%), healthy group (55.71%), and inactive group (29.48%). Sex, age, years of education, current residence, living arrangement, average annual household income, and currently employed were associated with the number of healthy behaviors. Compared with the participants in the healthy group, widowed/others (OR = 5.85, 95% CI = 3.27, 10.48), had 15,001-30,000 (OR = 2.05, 95% CI = 1.21, 3.47) and 60,001 or higher (OR = 3.78, 95% CI = 1.26, 11.36) average annual household income, and currently employed (OR = 3.40, 95% CI = 1.99, 5.81) were highly associated with risk group. Additionally, the participants who are widowed/others (OR = 4.30, 95% CI = 2.70, 6.85) and currently employed (OR = 1.95, 95% CI = 1.27, 2.98) were highly associated with the inactive group.

Conclusion

This study identified factors specifically associated with older Hakka adults' health-related behaviors from an LCA perspective. The findings indicate that policymakers should give more attention to older adults living alone and implement practical interventions to promote health-related behaviors among them.

The healthy eating index for older adults: adaptation of the 2015 healthy eating index considering dietary guidelines for healthy aging

INTRODUCTION

The Healthy Eating Index (HEI) is a comprehensive measure to assess diet quality. Because of the various factors that influence the nutritional status of older adults, there is a need to adapt an index that assesses the quality of the diet considering the dietary requirements of aging and health promotion. This study aimed to adapt the HEI for older adults, considering their needs for healthy eating.

METHODS

Food consumption data was collected by means of three non-consecutive 24-hour food recalls (R24h). For the adaptation of the Healthy Eating Index for Older Adults (HEI-OA), the components and scoring methodology of HEI-2015 were maintained and Brazilian food intake recommendations for the older population were used, which are in line with international recommendations. The validity of the HEI-OA was assessed by four ideal diets, Mann-Whitney's test, Spearman's correlation analysis and Cronbach's coefficient.

RESULTS

Content validity of the HEI-OA was confirmed by the maximum score for diets recommended to older adults and by the score between groups with known differences in diet quality. The HEI-OA total score did not correlate with total energy intake (TEI - total energy value: r = -0.141, p > 0.05). The total HEI-OA score showed a statistically significant correlation with several nutrients. These correlations allowed identifying that these nutrients are closely related to the components of the HEI-OA. The internal consistency value for the HEI-OA total score was 0.327, similar to the 2005 and 2010 versions of the HEI.

CONCLUSION

The HEI was successfully adapted for use with older adults, presenting validity and reliability. The HEI-OA can be used to assess diet quality in line with international dietary guidelines for healthy aging.

Supporting each other: Older adults' experiences empowering food security and social inclusion in rural and food desert communities

Older adults vulnerable to food insecurity are at risk of poor psychological and physical health. Poor public infrastructure or proximity to food sources can exacerbate risk of food insecurity. Reduced statutory services for social care has heightened the responsibility on third sector organisations and community-led volunteering, essential to supporting healthy ageing in place and reducing the inequalities of ageing. The aim of this qualitative study was to explore how older adults' volunteering with a third sector organisation focused on food access supports food security and builds social capital for socially or economically marginalised older adults within rural and food desert communities. The study aims to bridge the knowledge gap of how volunteering in vulnerable geographies affects food insecurity and community. Semi-structured interviews were conducted with seven older (55+) volunteer 'meal makers' working with the third sector organisation Food Train and its 'Meal Makers' project. Interview recordings were transcribed and thematically analysed. Ecomap methodology was used to illustrate the lived experiences of older adult volunteers as told through the interviews. Two themes were identified by Thematic Analysis: (1) Networks, connectedness, and exposure to social capital, and (2) Supplementary support. This study finds that older adult volunteers are well placed within community interventions supporting food insecure older adults in rural or food desert communities. Ecomaps demonstrated that high social capital volunteers can mediate food access barriers and highlighted points of local knowledge and social connection. Volunteer engagement provides opportunities for food secure older adults to share local knowledge and build networks of food support and social inclusion for food insecure older adults. Older age volunteering should be advocated as a multi-faceted intervention promoting mutual health and wellbeing in volunteer and beneficiary.

Association of Higher Mediterranean Diet Adherence With Lower Prevalence of Disability and Symptom Severity, Depression, Anxiety, Stress, Sleep Quality, Cognitive Impairment, and Physical Inactivity in Older Adults With Multiple Sclerosis

A good nutritional status and healthy diets may decelerate disease disability and symptom severity and quality of life of peoples with multiple sclerosis (MS). Mediterranean diet (MD) can prevent several chronic diseases, including neurodegenerative disease. This is an observational, cross-sectional study on 279 older adults with MS, aiming to investigate the effects of MD against several aspects of mental health. Qualified questionnaires were used to assess disability and symptom severity, depression, anxiety, stress, sleep quality, cognitive status, physical activity, and MD adherence. Multivariate analysis showed that enhanced MD adherence was independently associated with lower prevalence of disability and symptom severity (P = .0019), depression (P = .0201), anxiety (P = .0287), perceived stress (P = .0021), inadequate sleep quality (P = .0033), cognitive impairment (P = .0018) and physical inactivity (P = .0028). Adopting MD may ameliorate mental health disturbances in older adults with MS. Future public health policies should inform older adults with MS for the favorable impacts of MD in improving the mental health MS comorbidities.

Cognition of diet quality and dietary management in elderly patients with coronary and other atherosclerotic vascular disease in western China, a qualitative research study

BACKGROUND

Healthy eating is one of the most important nonpharmacologic treatments for patients with atherosclerosis(AS). However, it is unclear how elderly AS patients in western China perceive their dietary status and which type of nutritional assistance they would be willing to receive. Therefore, the primary purpose of this study was to understand the level of knowledge about current dietary habits and healthy eating habits among elderly AS patients in western China, and the secondary purpose was to identify acceptable nutritional assistance measures or pathways for those patients to help them manage disease progression.

METHODS

An implementation study approach was used to recruit elderly patients with AS-related diseases in western China for semistructured interviews.

RESULTS

14 participants were included in the study, and the following three themes were identified from the interviews:(1) the diet with regional characteristics; (2) low nutrition-related health literacy; (3) complex attitudes towards nutritional assistance. Most participants had misconceptions about healthy eating, and the sources of their knowledge might not be trustworthy. Participants expressed a preference for personalized nutritional assistance, especially that provided by medical-nursing combined institutions.

CONCLUSION

Patients in western China need nutritional assistance for their regional dietary habits; therefore, healthy dietary patterns consistent with the regional culture are proposed to improve the prevailing lack of knowledge about healthy diets, improve the dietary structure of patients, and control the development of the disease.

Exercise and Nutrition in the Mental Health of the Older Adult Population: A Randomized Controlled Clinical Trial

(1) Background: Global population aging is changing demographic structures and presents significant challenges for health systems, which must adapt to an increasingly elderly population. (2) Methods: The study employed a randomized controlled trial design with a total of 116 older adults aged 65 or older, randomly assigned to an experimental group (n = 57) undergoing a combined resistance program and Mediterranean diet program and a control group (n = 59) who did not receive any intervention. Anxiety and depression were evaluated using the Hospital Anxiety and Depression Scale (HADS), sleep quality through the Pittsburgh Sleep Quality Index (PSQI), and perceived stress using the Perceived Stress Scale (PSS). (3) Results: Statistically significant improvements (p < 0.05) were observed both within and between groups in anxiety (Cohen's d = 0.38 and 0.78, respectively), depression (Cohen's d = 0.56 and 0.18, respectively), perceived stress (Cohen's d = 0.15 and 0.39, respectively), and in the PSQI domains: subjective sleep quality (Cohen's d = 1.01 and 0.53, respectively), sleep duration (Cohen's d = 0.112 and 0.53, respectively), sleep disturbances (Cohen's d = 1.92 and 0.95, respectively), use of medications (Cohen's d = 0.34 and 0.40, respectively), and the PSQI total score (Cohen's d = 0.68 and 0.49, respectively). No significant differences were observed in sleep latency or daytime dysfunction. (4) Conclusions: The results of the present study suggest that resistance intervention may be an effective therapeutic option to improve mental health and sleep quality in older adults aged 65 or older, offering a non-pharmacological approach to improving overall well-being in this demographic.

The effects of social pensions on nutrition-related health outcomes of the poor: Quasi-experimental evidence from Peru

This paper exploits the discontinuity around a welfare index of eligibility to assess the impact of Peru's social pension program Pension 65 on nutrition-related health outcomes among elderly poor individuals. Overall, we find evidence of how a relatively inexpensive program can produce improvements in anemia and nutrition-related mortality risk markers. The effects appear to be driven by plausible underlying mechanisms, including via improved nutritional quality as well as greater food expenditures and healthcare utilization. These positive effects are only modestly countered by tentative signs of an increased obesity risk among women in the short term (<2 years), but not beyond this term. As the program evolves further, policymakers need to confront the challenge of continuing to ensure the health benefits in terms of reducing nutritional deficits while avoiding potential undesirable side effects in terms of over-nutrition in Peru. The findings may serve to highlight the wider benefits of similar pension policies for the poor also in other middle income countries, well beyond the immediate economic welfare effects that the policies have primarily been designed for.

Cost-effectiveness of telehealth-delivered diet and exercise interventions: A systematic review

OBJECTIVES

Telehealth is a promising tool for delivering lifestyle interventions for the management of health conditions. However, limited evidence exists regarding the cost-effectiveness of these interventions. This systematic review aimed to evaluate the current literature reporting on the cost-effectiveness of telehealth-delivered diet and/or exercise interventions.

METHODS

Four electronic databases (PubMed, CENTRAL, CINAHL and Embase) were searched for published literature from database inception to November 2020. This review adhered to the preferred reporting items for systematic reviews and meta-analyses guidelines and the ISPOR Criteria for Cost-Effectiveness Review Outcomes Checklist. The quality of reporting was assessed using the Consolidated Health Economic Evaluation Reporting Standards checklist. The extracted data were grouped into subcategories according to telehealth modality, organised into tables and reported narratively.

RESULTS

Twenty-four studies of controlled trials (11 combined diet and exercise, 9 exercise-only and 4 diet-only telehealth-delivered interventions) were included for data extraction and quality assessment. Interventions were reported as cost-effective in 12 studies (50%), five studies (21%) reported inconclusive results, and seven studies (29%) reported that the interventions were not cost-effective. Telephone interventions were applied in eight studies (33%), seven studies (29%) used internet interventions, six studies (25%) used a combination of internet and telephone interventions, and three studies (13%) evaluated mHealth interventions. Quality of study reporting varied with between 54% and 92% of Consolidated Health Economic Evaluation Reporting Standards items reported.

CONCLUSIONS

This review suggests that telehealth-delivered lifestyle interventions can be cost-effective compared to traditional care. There is a need for further investigations that employ rigorous methodology and economic reporting, including appropriate decision analytical models and longer timeframes.

Association of Mediterranean diet adherence with disease progression, quality of life and physical activity, sociodemographic and anthropometric parameters, and serum biomarkers in community-dwelling older adults with multiple sclerosis: a cross-sectional study

BACKGROUND

Multiple sclerosis (MS) constitutes a chronic inflammatory and degenerative demyelinating disease, which can progressively lead to a broad range of sensorimotor, cognitive, visual, and autonomic function symptoms, independently of patient' age. However, the clinical studies that examine the role of dietary patterns against disease progression and symptomatology remain extremely scarce, especially concerning Mediterranean diet (MD) in the subgroup age of older adults with MS.

AIMS

The present study aimed to investigate the potential impact of MD compliance in disease progression and symptoms severity as well as quality of life and physical activity of community-dwelling older adults with MS.

METHODS

This is a cross-sectional conducted on 227 older adults with no history of other severe disease. Relevant questionnaires were applied to collect sociodemographic and anthropometric factors by face-to face interviews between patients and qualified personnel. Serum biomarkers were retrieved by patients' medical records.

RESULTS

Higher MD compliance was independently associated with younger patients' age, lower risk of overweight/obesity and abdominal obesity, decreased disease progression and higher muscle mass, as well as greater physical activity, better quality of life, and adequate serum ferritin and albumin levels CONCLUSIONS: MD may exert beneficial effects in older adults with MS. Future strategies and policies are highly recommended to inform both the general population and the older patients with MS for the beneficial effects of MD in preventing MS and in improving or even slowing down the disease progression and symptoms severity of MS.

Life After Retirement: Exploring the Survival Strategies of SSNIT Pensioners in the Greater Accra Region of Ghana

Ghana's elderly population represents about 6.7% of the national populace. They comprise persons aged sixty years and above, including retirees. The main source of income for some of these individuals, particularly those who worked in the formal sector is the monthly pension they receive as compensation for contributing to Ghana's public pension scheme known as the Social Security and National Insurance Trust (SSNIT) while they were working. However, some beneficiaries of the scheme have raised concerns about the inadequacy of the pension income. Old age is accompanied by other social, economic, and health issues that tend to be detrimental to one's well-being. In this study, the survival strategies adopted by SSNIT pensioners to assuage the challenges they encounter, mainly due to inadequate pensions were explored. The mixed-methods research design was employed to gather data from 437 respondents. Whereas the quantitative findings were analyzed via the Stata software, the framework approach was adopted to analyze the qualitative data. The majority (78.7%) of the pensioners indicated that their pensions were insufficient to meet their needs. In their quest to address the challenges confronting them, the pensioners either adopted survival strategies they considered suitable or resorted to other non-prioritized coping mechanisms perceived to be relevant only in times of urgent necessity. Based on the findings of the study, some recommendations for policy and practice were presented.

Understanding the health benefits and technological properties of β-glucan for the development of easy-to-swallow gels to guarantee food security among seniors

The world's population is growing rapidly and the number of elderly people with undernutrition and malnutrition is increasing. Common health problems among seniors are cardiovascular, inflammatory, gastrointestinal, and cognitive disorders, cancer, diabetes, psychological and dental problems. The food industry is trying to meet the demands of an aging society, but these efforts are not sufficient. New strategies are needed, and they demand foods development with modified textures that are easy to swallow, such as gels suitable for seniors. Depending on the specific needs of the elderly, bioactive compounds with health benefits should be included in food systems. Novel foods may play an important role in the prevention, maintenance, and treatment of age-related diseases. One of the most studied bioactive compound is β-glucan, a polysaccharide with approved health claims confirmed by clinical trials, such as "β-glucan contributes to the maintenance of normal blood cholesterol levels" and "the consumption of β-glucan from oats or barley contributes to the reduction of postprandial glucose spikes." In this review, the health benefits, and technological properties of β-glucan for the development of senior-friendly ready-to-swallow gels were described. In addition, some patents and studies conducted in connection with the development of the gel systems were collected.

The ability of the geriatric nutritional risk index to predict the risk of heart diseases in Korean adults: a Korean Genome and Epidemiology Study cohort

Introduction

The predictive ability of nutritional risk index on cardiovascular outcomes in middle-aged and non-hospitalized adults has not yet been reported. This study investigated whether the Geriatric Nutritional Risk Index (GNRI), an index for assessing the risk of developing malnutrition, could predict heart disease in middle-aged Korean adults.

Methods

The cohort used in this study consisted of 3,783 participants selected from 10,030 Korean adults who participated in the Ansan-Ansung cohort study as part of the Korean Genome and Epidemiology Study. The GNRI was determined based on serum albumin level, proportion of current weight, and ideal body weight. Participants were then divided into two groups: GNRI ≤98 and > 98, which corresponded to the risk of malnutrition and normal, respectively. The major outcome of this study was coronary artery disease (CAD) or congestive heart failure (CHF) during a 15-year-follow period.

Results

During the follow-up period spanning 2004-2018, 136 events of heart disease occurred. Using a Kaplan-Meier analysis, event-free rates were found to be associated with 90.5% on a GNRI ≤98 and 96.6% on a GNRI >98 (p < 0.0009). GNRI ≤98 showed a 3.2-fold (hazard ratio, 3.22; 95% credit interval, 1.49-6.96; p = 0.0029) increase in the incidence of heart disease, including CAD or CHF, compared with GNRI >98, after controlling for potential confounders.

Conclusion

Malnutrition risk confers a significantly increased risk for heart disease in middle-aged Koreans. Further studies with larger cohorts are needed to verify the efficacy of the GNRI in predicting disease risk in adults with pre-disease.

Factors associated with eating behaviors in older adults from a socioecological model perspective

BACKGROUND

The eating behaviors of older adults are associated with multiple factors. To promote older adults' healthy diets, it is imperative to comprehensively study the factors associated with the eating behaviors of the aging population group. This study aimed to probe the associated factors of older adults' eating behaviors from a socioecological model (SEM) perspective.

METHODS

In 2021, a cross-sectional survey was performed to recruit participants in China. The survey data were analyzed using a multivariate generalized linear model to identify the factors associated with eating behaviors in older adults. Standardized regression coefficients (β) and 95% confidence intervals (CIs) were estimated using a multivariate generalized linear model.

RESULTS

The survey contained 1147 valid older adult participants. Multivariate generalized linear model results showed that older adults with older age [aged 71-80 (β = -0.61), ≥ 81 (β = -1.12)], conscientiousness personality trait (β = -0.27), and higher family health levels (β = -0.23) were inclined to have better eating behaviors. The older adults with higher education levels [junior high school and high school (β = 1.03), junior college and above (β = 1.71)], higher general self-efficacy (β = 0.09), more severe depression symptoms (β = 0.24), and employment (β = 0.82) tended to have poorer eating behaviors.

CONCLUSIONS

This study identified factors that are specifically associated with older adults' eating behaviors from an SEM perspective. The comprehensive multiple-angle perspective consideration may be a valuable idea for studying healthy eating behaviors in older adults.

A Bioelectrical Impedance Analysis in Adult Subjects: The Relationship between Phase Angle and Body Cell Mass

The correct assessment of body composition is essential for an accurate diagnostic evaluation of nutritional status. The body mass index (BMI) is the most widely adopted indicator for evaluating undernutrition, overweight, and obesity, but it is unsuitable for differentiating changes in body composition. In recent times, bioelectrical impedance analyses (BIA) have been proven as a more accurate procedure for the assessment of body composition. Furthermore, the efficiency of bioelectrical impedance vector analyses, as an indicator of nutritional status and hydration, has been demonstrated. By applying a bioimpedance analysis, it is possible to detect fat mass (FM), fat free mass (FFM), phase angle, and body cell mass (BCM). It is important to point out that phase angle and BCM are strongly associated with health status. The aim of this research was to examine body composition and the association between the phase angle and BCM in 87 subjects (14 males and 73 females), aged between 23 and 54 years, with BMIs ranging from 17.0 to 32.0 kg/m2, according to sex. The BMI results revealed that the majority of the assessed subjects were within the normal range and had a normal percentage of FM. Our data indicate that a direct relation exists between phase angle and cellular health and that these values increase almost linearly. Consequently, a high phase angle may be related to increased BCM values.

Examining Physical Wellness as the Fundamental Element for Achieving Holistic Well-Being in Older Persons: Review of Literature and Practical Application in Daily Life

This review examines the impact of physical activity, nutrition, and sleep evaluations on the physical wellness (PW) and overall well-being of older individuals. A comprehensive search was conducted in databases like PubMed, Google Scholar, and EBSCO Information Services. The search spanned from January 2000 to December 2022, resulting in 19,400 articles, out of which 98 review articles met the inclusion criteria. Through the analysis of these articles, key characteristics of the literature were summarized, and opportunities to enhance the practical application of physical activity (PA), nutrition, and sleep evaluations in the daily lives of older persons were identified. Regular physical activity is crucial for older persons to maintain their physical, mental, and emotional well-being and prevent age-related health issues. Older persons have specific nutritional needs, including increased protein, vitamin D, calcium, and vitamin B12 intake. Poor sleep quality in older persons is associated with negative health outcomes such as cognitive decline, physical disability, and mortality. This review emphasizes the significance of considering physical wellness as a fundamental element for achieving holistic well-being in older persons and highlights the importance of physical activity, nutrition, and sleep evaluations in improving their overall health and well-being. By understanding and implementing these findings, we can enhance the quality of life and promote healthy aging in older persons.

Association between the anthropometric measurements and dietary habits on telomere shortening in healthy older adults: A-cross-sectional study

AIM

This study aimed to evaluate the effect of anthropometric measurements and dietary habits on telomere length in healthy older residents in rural and urban areas.

METHODS

This was a cross-sectional study. The study population included 81 healthy older individuals aged ≥80 years. A quantitative food frequency questionnaire was used to determine dietary habits. Anthropometric measurements were taken by researchers. The telomere length of individuals was determined from leukocytes using quantitative polymerase chain reaction.

RESULTS

Urban women had longer telomeres than rural women (P < 0.05). Rural men had significantly higher hip circumference, middle-upper arm circumference and fat-free mass than urban men (P < 0.05). It was shown that while fresh vegetable consumption was higher in rural areas, carbonated drink consumption was higher in urban areas (P < 0.05). In women, homemade bread and sugar consumption were higher in rural areas, and honey consumption was higher in urban (P < 0.05). Red meat, milk-based dessert and pastry consumption explain telomere shortening by 22.5%, 24.8% and 17.9%, respectively. In addition, the model based on anthropometric measurements also contributes to explaining telomere shortening by 42.9%.

CONCLUSION

Red meat, milk-based dessert and pastry consumption, and waist circumference, hip circumference, waist-to-hip ratio and waist-to-height ratio are associated with telomere length. Longer telomeres are associated with a healthy, balanced, adequate diet and maintaining a healthy body weight/proportion, and they are crucial for achieving healthy aging.

The Relationship of Food Insecurity to Nutritional Risk in Independent Living Older Adults

Understanding the factors that augment optimal health during aging is critical as the US older adult population is increasing. Most research about food insecurity, nutritional risk, and perceived health among older adults are in urban areas or congregate living facilities. Thus, the purpose of this project was to study the relationships among these factors, plus activities of daily living, in community-dwelling older adults in a medium-sized city. Using a qualitative-quantitative study design, a cross-sectional survey was completed by 167 low-income senior apartment residents. Food insecurity in this group was higher than the national and state rate, yet nutrition assistance programs were underutilized and participants under 75 years were more food insecure than their older counterparts. Food insecure residents were at greater nutritional risk, had poorer self-reported health status, were more likely to be depressed, and had a less independent function, including limitations on the ability to shop for and prepare food. The study area is desirable to retirees due to lower cost of living; however, access to services, such as grocery stores, public transportation, and health care providers is limited. This research indicates the need for increased outreach, nutrition assistance, and support services to ensure healthy aging in these regions.

Nutritional and lifestyle management of the aging journey: A narrative review

With age, the physiological responses to occasional or regular stressors from a broad range of functions tend to change and adjust at a different pace and restoring these functions in the normal healthy range becomes increasingly challenging. Even if this natural decline is somehow unavoidable, opportunities exist to slow down and attenuate the impact of advancing age on major physiological processes which, when weakened, constitute the hallmarks of aging. This narrative review revisits the current knowledge related to the aging process and its impact on key metabolic functions including immune, digestive, nervous, musculoskeletal, and cardiovascular functions; and revisits insights into the important biological targets that could inspire effective strategies to promote healthy aging.

Nutritional Status Is Associated with Health-Related Quality of Life, Physical Activity, and Sleep Quality: A Cross-Sectional Study in an Elderly Greek Population

This study aims to explore the associations between nutritional status and health-related quality of life, physical activity, and sleep quality in older exclusively Caucasian adults from Greec who were free of any severe disease. This is a cross-sectional study. Mini Nutritional Assessment was used to assess nutritional status, health-related quality of life was assessed using the Short Form Healthy Survey questionnaire, sleep quality was assessed using the Pittsburgh Sleep Quality Index, and physical activity levels were assessed via the International Physical Activity Questionnaire. 3405 community-dwelling men and women, over 65 years old from14 different Greek regions were enrolled. Ten-point four percent (10.4%) of the participants were classified as malnourished, while 35.6% were "at risk of malnutrition". A better nutritional status was significantly and independently associated with higher physical activity levels (p = 0.0011) and better quality of life (p = 0.0135), as well as better sleep quality (p = 0.0202). In conclusion, our study highlights the interrelationships between a good nutritional status, a high-quality sleep, active lifestyle, and good quality of life. Further interventional studies are needed to clarify the associations, and test the feasibility of improving the nutritional status, physical activity levels and sleep quality of the elderly, and the impact of these changes on quality of life, and healthy ageing in races beyond Caucasian populations. Public health strategies and policies should be recommended to inform older adults for the necessity to improve their nutritional status and lifestyle habits to improve their health status and to obtain better life expectancy.

The socioecological correlates of meal skipping in community-dwelling older adults: a systematic review

CONTEXT

Meal skipping may contribute to nutrient deficiency across the lifespan. Multiple socioecological factors have been identified as correlates of meal skipping in adolescents and adults, but evidence in older adults is limited.

OBJECTIVE

To determine the socioecological correlates of meal skipping in community-dwelling older adults.

DATA SOURCE

Embase, PsycINFO, CINAHL, and MEDLINE electronic databases were systematically searched from inception to March 2021.

DATA EXTRACTION

A total of 473 original research studies on socioecological factors and meal skipping among community-dwelling adults aged ≥65 years were identified. Title, abstract, and full-text review was performed by 2 reviewers independently, and a third reviewer resolved disagreements. A total of 23 studies met our inclusion criteria. Data were extracted by 1 reviewer from these studies and independently verified by another. The Newcastle-Ottawa Scale was used to assess methodological quality.

DATA ANALYSIS

The frequency of meal skipping in included studies ranged between 2.1% and 61%. This review identified 5 domains of socioecological correlates associated with meal skipping in older adults: sociodemographic, behavioral, biomedical, psychological, and social.

CONCLUSION

Understanding the factors associated with meal skipping in older adults can inform the development of targeted interventions to improve nutrition and health.

Targeting AMPK signaling by polyphenols: a novel strategy for tackling aging

Aging is an inevitable biological process and is accompanied by a gradual decline of physiological functions, such as the incidence of age-related diseases. Aging becomes a major burden and challenge for society to prevent or delay the occurrence and development of these age-related diseases. AMPK is a key regulator of intracellular energy and participates in the adaptation of calorie restriction. It is also an important mediator of nutritionally sensitive pathways that regulate the biological effects of nutrient active ingredients. AMPK can limit proliferation and activate autophagy. Recent studies have shown that nutritional intervention can delay aging and lessen age-related diseases in many animal and even human models. Polyphenols function as a natural antidote and are important anti-inflammatory and antioxidant agents in human diets. Polyphenols can prevent age-related diseases because they regulate complex networks of cellular processes such as oxidative damage, inflammation, cellular aging, and autophagy, and have also attracted wide attention as a potential beneficial substance for longevity. In this review, we systemically summarized the progress of targeting AMPK signaling by dietary polyphenols in aging prevention. Polyphenols can reduce oxidative stress and inflammatory response, and maintain the steady state of energy. Polyphenols can also modulate sirtuins/NAD+, nutrient-sensing, proteostasis, mitochondrial function, autophagy and senescence via targeting AMPK signaling. Therefore, targeting the AMPK signaling pathway by dietary polyphenols may be a novel anti-aging strategy.

Oral nutritional interventions in frail older people who are malnourished or at risk of malnutrition: a systematic review

BACKGROUND

Malnutrition worsens the health of frail older adults. Current treatments for malnutrition may include prescribed oral nutritional supplements, which are multinutrient products containing macronutrients and micronutrients.

OBJECTIVE

To assess the effectiveness and cost-effectiveness of oral nutritional supplements (with or without other dietary interventions) in frail older people who are malnourished or at risk of malnutrition.

DATA SOURCES

MEDLINE, EMBASE, Cochrane Library, Scopus, CINAHL (Cumulative Index to Nursing and Allied Health Literature) and grey literature were searched from inception to 13 September 2021.

REVIEW METHODS

A systematic review and meta-analysis was conducted to evaluate the effectiveness and cost-effectiveness of oral nutritional supplements in frail older people (aged ≥ 65 years) who are malnourished or at risk of malnutrition (defined as undernutrition as per National Institute for Health and Care Excellence guidelines). Meta-analysis and network meta-analysis were undertaken, where feasible, along with a narrative synthesis. A cost-effectiveness review was reported narratively. A de novo model was developed using effectiveness evidence identified in the systematic review to estimate the cost-effectiveness of oral nutritional supplements.

RESULTS

Eleven studies (n = 822 participants) were included in the effectiveness review, six of which were fully or partly funded by industry. Meta-analyses suggested positive effects of oral nutritional supplements compared with standard care for energy intake (kcal) (standardised mean difference 1.02, 95% confidence interval 0.15 to 1.88; very low quality evidence) and poor mobility (mean difference 0.03, p < 0.00001, 95% confidence interval 0.02 to 0.04; very low quality evidence) but no evidence of an effect for body weight (mean difference 1.31, 95% confidence interval -0.05 to 2.66; very low quality evidence) and body mass index (mean difference 0.54, 95% confidence interval -0.03 to 1.11; very low quality evidence). Pooled results for other outcomes were statistically non-significant. There was mixed narrative evidence regarding the effect of oral nutritional supplements on quality of life. Network meta-analysis could be conducted only for body weight and grip strength; there was evidence of an effect for oral nutritional supplements compared with standard care for body weight only. Study quality was mixed; the randomisation method was typically poorly reported. One economic evaluation, in a care home setting, was included. This was a well-conducted study showing that oral nutritional supplements could be cost-effective. Cost-effectiveness analysis suggested that oral nutritional supplements may only be cost-effective for people with lower body mass index (< 21 kg/m2) using cheaper oral nutritional supplements products that require minimal staff time to administer.

LIMITATIONS

The review scope was narrow in focus as few primary studies used frailty measures (or our proxy criteria). This resulted in only 11 included studies. The small evidence base and varied quality of evidence meant that it was not possible to determine accurate estimates of the effectiveness or cost-effectiveness of oral nutritional supplements. Furthermore, only English-language publications were considered.

CONCLUSIONS

Overall, the review found little evidence of oral nutritional supplements having significant effects on reducing malnutrition or its adverse outcomes in frail older adults.

FUTURE WORK

Future research should focus on independent, high-quality, adequately powered studies to investigate oral nutritional supplements alongside other nutritional interventions, with longer-term follow-up and detailed analysis of determinants, intervention components and cost-effectiveness.

Opportunities and barriers for food intake in older age - a Norwegian perspective

Background

The ageing processes occur slowly over time and are often not detectable by the individual. Thus, preparing for dietary needs in later years should start at an earlier age than most people realise.

Objective

This study aims at better understanding what characterises food-related practices in active, home-living older adults, in order to identify food-related factors that act as barriers and those that promote healthy ageing.

Design

Three experiments were conducted: First, a web-based quantitative survey to collect information about home-living older adults' food-related behaviours (67+ years, N = 1,005). Second, two focus groups with respondents 67-74 years (N = 7) and 75-84 years (N = 6) to elicit aspects not adequately covered in the survey. Third, 10 individual interviews to provide in-depth insights.

Results

Two distinct groups were identified in the survey; 67-79 years and 80+ years. The older age group experienced more barriers and restrictions in food intake and food-related behaviours compared to the younger group. Good taste, routines and social settings were important for appetite and food intake.

Discussion

Using a mixed-methods approach proved valuable for extracting information and a better understanding of what impacts on food-related aspects amongst older adults. Strategies for upholding a healthy food intake involve establishing daily routines and meeting arenas where older adults can socialise and eat food together.

Conclusion

This study confirmed that knowledge of older adults' physical needs, barriers and abilities must be a part in preparation for a healthy diet.

Effect of aquatic resistance interval training and dietary education program on physical and psychological health in older women: Randomized controlled trial

Due to demographic changes, the world’s population is progressively aging. The physiological deterioration of the older adult may lead to reduced balance capacity and increased risk of falls, among others, due to the prevalence of degenerative diseases. Physical exercise can be effective in reducing the risk of disease and slowing functional decline in older people. The aim of the research is to test the effects of aquatic resistance training and dietary education on health indicators, strength, balance, functional autonomy, perception of satisfaction with life. Thirty-four participants aged 69 ± 4 years were randomly assigned into two groups: experimental (aquatic resistance interval training) and control group (no intervention). The intervention consisted of resistance training in an aquatic environment carried out for 14 weeks (three sessions per week: 60 min each). All variables were analyzed twice; pre - post intervention. Aquatic resistance training has positive effects on strength (p &lt; 0.001), functional self-sufficiency (p &lt; 0.001) and aerobic capacity (p &lt; 0.001), however, no significant differences were observed in the perception of satisfaction with life and balance. Research results suggest that older women who engage in regular, scheduled aquatic resistance training have greater autonomy in performing activities of daily living, agility, gait control, and body composition variables (lower fat compartment and greater muscle mass).

The unmet needs of older people in Nsawam, Ghana

Although healthy life expectancy is projected to be increasing among older people in Ghana, a high proportion and number of older people will live with functional disability, warranting their need for long-term care. We explored the expressions used by older people to describe their needs and preference of care and support. Using the descriptive qualitative approach, 14 older people were engaged via semi-structured interviews, and the data were analysed thematically. The study found that older people desired a decent accommodation, preferential healthcare, adequate nutrition, and an opportunity to interact with their peers at social functions. A provision of sufficient financial assistance, adequate healthcare, the periodic organisation of social and group events for older people, and the availability of home care and support could help older people address these needs. The paper reveals the need for interventional research on how a model incorporating social, health and environmental factors even during a pandemic can address older people's varying needs.

Caenorhabditis elegans as an emerging model in food and nutrition research: importance of standardizing base diet

As a model organism that has helped revolutionize life sciences, Caenorhabditis elegans has been increasingly used in nutrition research. Here we explore the tradeoffs between pros and cons of its use as a dietary model based primarily on literature review from the past decade. We first provide an overview of its experimental strengths as an animal model, focusing on lifespan and healthspan, behavioral and physiological phenotypes, and conservation of key nutritional pathways. We then summarize recent advances of its use in nutritional studies, e.g. food preference and feeding behavior, sugar status and metabolic reprogramming, lifetime and transgenerational nutrition tracking, and diet-microbiota-host interactions, highlighting cutting-edge technologies originated from or developed in C. elegans. We further review current challenges of using C. elegans as a nutritional model, followed by in-depth discussions on potential solutions. In particular, growth scales and throughputs, food uptake mode, and axenic culture of C. elegans are appraised in the context of food research. We also provide perspectives for future development of chemically defined nematode food ("NemaFood") for C. elegans, which is now widely accepted as a versatile and affordable in vivo model and has begun to show transformative potential to pioneer nutrition science.

Pension exposure and health: Evidence from a longitudinal study in South Africa

Social protection schemes have been expanding around the world with the objective of protecting older persons during retirement. While theoretically they have been seen as tools to improve individual wellbeing, there are few studies that evaluate whether social pensions can improve health. In this study, we exploit the change in eligibility criteria for the South African Old Age grant to estimate the association between pension exposure eligibility and health of older persons. For this, we use data from the Health and Aging in Africa: A longitudinal Study of an INDEPTH Community in South Africa (HAALSI) and model pension exposure in terms of its cumulative effect. Our results show that pension exposure is associated with better health as measured by a set of health indices. Disentangling these effects, we find that pension exposure is most likely to improve health through the delayed onset of physical disabilities in the elderly population. Our study highlights the relevance of social protection schemes as a mechanism to protect older persons physical health.

Effectiveness and cost-effectiveness of oral nutritional supplements in frail older people who are malnourished or at risk of malnutrition: a systematic review and meta-analysis

BACKGROUND

Current management of malnutrition can include prescribed oral nutritional supplements (ONS); however, there is uncertainty whether these supplements are effective in people who are older (≥65 years) and frail. We assessed the effectiveness, cost-effectiveness, and adherence and acceptability of ONS in frail older people who are malnourished or at risk of malnutrition.

METHODS

In this systematic review and meta-analysis, five bibliographic databases (MEDLINE, EMBASE, Cochrane Library, Scopus, and CINAHL) and grey literature sources were searched from inception to Sept 13, 2021, to identify studies assessing the effectiveness and cost-effectiveness of ONS (with or without other dietary interventions) in frail older people who are malnourished or at risk of malnutrition. Multiple reviewers independently did study screening, data extraction, and risk of bias assessment. Quality was assessed using version 1.0 of the Cochrane risk of bias tool for randomised controlled trials (RCTs), and the BMJ Drummond checklist was used to assess the quality of the included cost-effectiveness study. A meta-analysis was done for the effectiveness review; for the other reviews, a narrative synthesis approach was used. This systematic review and meta-analysis was registered on PROSPERO, CRD42020170906.

FINDINGS

Of 8492 records retrieved and screened, we included 11 RCTs involving 822 participants, six of which were fully or partly funded by industry. For the majority of the outcomes for which meta-analyses were possible (11/12), Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) assessments suggested that the evidence was of very low certainty. Results suggested that ONS might have a slightly positive effect on energy (kcal) intake (standardised mean difference 1·02 [95% CI 0·15 to 1·88]; I²=87%; four studies), protein intake (standardised mean difference 1·67 [-0·03 to 3·37; I²=97%; four studies), and mobility (mean difference 0·03 [0·02 to 0·04]; I²=0%; four studies), compared with standard care. Narrative syntheses suggested that the effect of ONS on quality of life, compared with standard care, was mixed. In the identified studies, there was very little information related to active components, determinants, or acceptability of interventions. One economic evaluation, done in a care home setting, showed that ONS could be cost-effective.

INTERPRETATION

We found little evidence of ONS reducing malnutrition or its associated adverse outcomes in older people who are frail. High-quality, non-industry-funded, adequately powered studies reporting on short-term and long-term health outcomes, determinants, and participant characteristics are needed.

Nutrition-Focused Care for Community-Living Adults: Healthcare Utilization and Economic Benefits

OBJECTIVES

We assessed the impact of a recently reported nutritional quality improvement program (QIP) on healthcare resource utilization and costs for older, community-living adults in Bogotá, Colombia.

METHODS

The study included 618 community-dwelling, older adults (> 60 years) who were at risk or malnourished and receiving outpatient clinical care. The intervention was a QIP that emphasized nutritional screening, dietary education, lifestyle counseling, 60-day consumption of oral nutritional supplements, and 90-day follow-up. For economic modeling, we performed 90-day budget impact and cost-effectiveness analyses from a Colombian third-party payer perspective. The base-case analysis quantified mean healthcare resource use in the QIP study population. Analysis was based on mean input values (deterministic) and distributions of input parameters (probabilistic). As the deterministic analysis provided a simple point estimate, the cost-effectiveness analysis focused on the probabilistic results informed by 1000 iterations of a Monte-Carlo simulation.

RESULTS

Results showed that the total use of healthcare resources over 90 days was significantly reduced by > 40% (hospitalizations were reduced by approximately 80%, emergency department visits by > 60%, and outpatient clinical visits by nearly 40%; P < .001). Based on economic modeling, total cost savings of $129 740 or per-patient cost savings of $210 over 90 days could be attributed to the use of nutritional QIP strategies. Total cost savings equated to nearly twice the initial investment for QIP intervention; that is, the per-dollar return on investment was $1.82.

CONCLUSIONS

For older adults living in the community in Colombia, the use of our nutritional QIP improved health outcomes while lowering costs of healthcare and was thus cost-effective.

Malnutrition-related conditions and interventions in US state/territorial Older Americans Act aging plans

Background

Factors that decrease independence and increase morbidity must be reduced to improve the nutrition, health, and other challenges confronting older adults. In the United States (US), the Older Americans Act (OAA) requires each state/territory develop multi-year aging plans for spending federal funds that foster healthy aging (including support of congregate/home delivered meals programs) and separately requires grant applications for nutrition service programs supporting older Native Americans. Malnutrition (particularly protein-energy undernutrition), sarcopenia, frailty, and obesity can all result in disability but are potentially changeable. The study goal was to collect baseline information on mentions of these malnutrition-related conditions and interventions that address them in US state/territorial OAA program multi-year aging plans.

Methods

OAA program multi-year aging plans available on the ADvancing States website in February 2021 (n = 52) were searched for number of mentions of defined nutrition terms including malnutrition, sarcopenia, frailty, obesity, and whether terms were included in plans’ goals/objectives, strategies/actions, or solely in the narrative.

Results

Malnutrition, sarcopenia, frailty, and obesity were mentioned infrequently in US state/territorial OAA program multi-year aging plans. 33% of plans mentioned malnutrition but only 8% as goals/objectives and 15% as strategies/actions. 62% mentioned frailty; 6% (goals/objectives), 15% (strategies/actions). None mentioned sarcopenia whereas in contrast, 21% mentioned obesity; 2% (goals/objectives), 2% (strategies/actions). Nutrition intervention mentions were nearly nil. There were no significant differences in frequency of term mentions by US region or by states with higher percentages of older adults or obese adults.

Conclusions

Clearly specifying definitions of malnutrition-related conditions and incorporating them into measurable goals/objectives, defined strategies/actions, and outcomes may help improve future state/territorial OAA program multi-year aging plans to better support healthy aging.

The fourth industrial revolution in the food industry-part II: Emerging food trends

The food industry has recently been under unprecedented pressure due to major global challenges, such as climate change, exponential increase in world population and urbanization, and the worldwide spread of new diseases and pandemics, such as the COVID-19. The fourth industrial revolution (Industry 4.0) has been gaining momentum since 2015 and has revolutionized the way in which food is produced, transported, stored, perceived, and consumed worldwide, leading to the emergence of new food trends. After reviewing Industry 4.0 technologies (e.g. artificial intelligence, smart sensors, robotics, blockchain, and the Internet of Things) in Part I of this work (Hassoun, Aït-Kaddour, et al. 2022. The fourth industrial revolution in the food industry-Part I: Industry 4.0 technologies. Critical Reviews in Food Science and Nutrition, 1-17.), this complimentary review will focus on emerging food trends (such as fortified and functional foods, additive manufacturing technologies, cultured meat, precision fermentation, and personalized food) and their connection with Industry 4.0 innovations. Implementation of new food trends has been associated with recent advances in Industry 4.0 technologies, enabling a range of new possibilities. The results show several positive food trends that reflect increased awareness of food chain actors of the food-related health and environmental impacts of food systems. Emergence of other food trends and higher consumer interest and engagement in the transition toward sustainable food development and innovative green strategies are expected in the future.

Beyond the Individual -A Scoping Review and Bibliometric Mapping of Ecological Determinants of Eating Behavior in Older Adults

Objectives: The objective of this scoping review was to summarize and provide a visual overview of the present-day knowledge on ecological determinants of eating behavior in community-dwelling elderly persons in relation with nutrition communication, considering the evolution of the field. The second objective was to integrate results in recommendations for the development of nutrition communication strategies.

Methods: A literature review was performed on Medline, PubMed and Google Scholar, according with the PRISMA protocol for scoping reviews. An a-priori analysis was executed by categorizing determinants from the literature according with the different levels represented in the ecological framework and an a-posteriori analysis by using VosViewer for a chronological bibliometric mapping analysis.

Results: Of 4029 articles retrieved, 77 were selected for analysis. Initial publications focused more on individual determinants of eating behavior. Over time, there was a shift towards a holistic view of eating behavior considering the “food environment”, including social networks, physical settings and public policy.

Conclusion: Beyond the individual, all ecological levels are relevant when targeting eating behavior in the elderly. Nutrition communication strategies should be structured considering these influences.

A Comparison between Dietary Consumption Status and Healthy Dietary Pattern among Adults Aged 55 and Older in China

The nutrition and health of middle-aged and elderly people is crucial to the long-term development of a country. The present study aimed to analyze the dietary consumption status in Chinese adults by using baseline and follow-up data from the community-based Cohort Study on Nervous System Diseases between 2018−2020 and selecting those aged 55 and older (n = 23,296). Dividing 65 food items into 17 subgroups on the basis of a valid semi-quantitative food frequency questionnaire, we analyze the consumption amount and consumption rate of foods in relation to wave and sociodemographic factors by employing the Wilcoxon rank sum test, Kruskal−Wallis analysis, the Chi-squared test, and the Cochran−Armitage trend test and evaluate food intake status using the Chinese Dietary Guidelines Recommendations (2022). Compared to 2018, the median daily intake of livestock meat, poultry, and eggs increased in 2020 (p < 0.05), while the median daily intake of wheat, other cereals, tubers, legumes, fruits, and fish and seafood decreased (p < 0.05). The proportion of subjects with excessive intake of grain, livestock and poultry, and eggs was 46.3%, 36.6%, and 26.6%, respectively, while the proportion of subjects with insufficient intake of whole grains and mixed beans, tubers, legumes, dairy products, fruits, vegetables, and fish and seafood were 98.4%, 80.3%, 74.0%, 94.6%, 94.3%, 75.8%, and 86.5%, respectively, and more than 50% of subjects were non-consumers of dairy products, nuts, and whole grains and mixed beans. In conclusion, the problem of unhealthy dietary structure is prominent among adults aged 55 and older in China; insufficient or excessive intakes of various types of foods are common; and excessive consumption of edible oil and salt remains a serious problem.

Regulation of Gene Expression through Food—Curcumin as a Sirtuin Activity Modulator

The sirtuin family comprises NAD⁺-dependent protein lysine deacylases, mammalian sirtuins being either nuclear (SIRT1, SIRT2, SIRT6, and SIRT7), mitochondrial (SIRT3, SIRT4, and SIRT5) or cytosolic enzymes (SIRT2 and SIRT5). They are able to catalyze direct metabolic reactions, thus regulating several physiological functions, such as energy metabolism, stress response, inflammation, cell survival, DNA repair, tissue regeneration, neuronal signaling, and even circadian rhythms. Based on these data, recent research was focused on finding molecules that could regulate sirtuins’ expression and/or activity, natural compounds being among the most promising in the field. Curcumin (1,7-bis-(4-hydroxy-3-methoxyphenyl)-1,6-heptadiene-3,5-dione) can induce, through SIRT, modulation of cancer cell senescence, improve endothelial cells protection against atherosclerotic factors, enhance muscle regeneration in atrophy models, and act as a pro-longevity factor counteracting the neurotoxicity of amyloid-beta. Although a plethora of protective effects was reported (antioxidant, anti-inflammatory, anticancer, etc.), its therapeutical use is limited due to its bioavailability issues. However, all the reported effects may be explained via the bioactivation theory, which postulates that curcumin’s observed actions are modulated via its metabolites and/or degradation products. The present article is focused on bringing together the literature data correlating the ability of curcumin and its metabolites to modulate SIRT activity and its consequent beneficial effects.

Fungal-Derived Mycoprotein and Health across the Lifespan: A Narrative Review

Mycoprotein is a filamentous fungal protein that was first identified in the 1960s. A growing number of publications have investigated inter-relationships between mycoprotein intakes and aspects of human health. A narrative review was undertaken focusing on evidence from randomized controlled trials, clinical trials, intervention, and observational studies. Fifteen key publications were identified and undertaken in early/young adulthood, adulthood (mid-life) or older/advanced age. Main findings showed that fungal mycoprotein could contribute to an array of health benefits across the lifespan including improved lipid profiles, glycaemic markers, dietary fibre intakes, satiety effects and muscle/myofibrillar protein synthesis. Continued research is needed which would be worthwhile at both ends of the lifespan spectrum and specific population sub-groups.

Influence of Sociodemographic, Health-Related, and Behavioral Factors on Food Guidelines Compliance in Older Adults: A Hierarchical Approach from the Chilean National Health Survey 2016-17 Data

Dietary habits are determinants in the development of a range of conditions and age-related diseases. We explored the associations of sociodemographic, health-related indicators, and health behavioral factors on dietary guideline compliance in elderly Chileans. We used a cross-sectional design using the publicly available database from the last Chilean National Health Survey (2016−17). The sample of 1831 older adults (≥60 y) from a national representative sample. The dependent variable was compliance with Food Guidelines (FG) (daily consumption of water, dairy, and fruits and vegetables; and weekly consumption of legumes and fish). The independent variables included sociodemographic, health-related, and behavioral factors. Over half (51.8%) of the sample was female and 85.7% belonged to the 60−79 age group. Satisfactory compliance to FG was observed in 3.9% of the sample. In the adjusted analysis, for those between 60 and 79 y, marital status was the only significant variable associated with FG noncompliance (PR: 1.34; 95%CI: 1.04−1.71). For those over 80 y, income of >2 minimum wages (PR: 0.10; 95%CI: 0.02−0.61), living alone (PR: 1.72; 95%CI: 1.20−2.47), and self-reported cardiovascular disease (PR: 0.63; 95%CI: 0.43−0.93) were associated with FG noncompliance. We observed low FG compliance among elderly Chilean adults, especially in the oldest group. Factors associated with the FG compliance was different between age groups.

Prevalence of Undernutrition, Frailty and Sarcopenia in Community-Dwelling People Aged 50 Years and Above: Systematic Review and Meta-Analysis

The world’s population aged ≥65 is expected to rise from one in eleven in 2019 to one in six by 2050. People aged ≥65 are at a risk of undernutrition, frailty, and sarcopenia. The association between these conditions is investigated in a hospital setting. However, there is little understanding about the overlap and adverse health outcomes of these conditions in community-dwelling people. This systematic review aims to quantify the reported prevalence and incidence of undernutrition, frailty, and sarcopenia among older people aged ≥50 living in community dwellings. Searches were conducted using six databases (AMED, CENTRAL, EMBASE, Web of Science, MEDLINE, and CINAHL), and 37 studies were included. Meta-analyses produced weighted combined estimates of prevalence for each condition (Metaprop, Stata V16/MP). The combined undernutrition prevalence was 17% (95% CI 0.01, 0.46, studies n = 5; participants = 4214), frailty was 13% (95% CI 0.11, 0.17 studies n = 28; participants = 95,036), and sarcopenia was 14% (95% CI 0.09, 0.20, studies n = 9; participants = 7656). Four studies reported incidence rates, of which three included data on frailty. Nearly one in five of those aged ≥50 was considered either undernourished, frail, or sarcopenic, with a higher occurrence in women, which may reflect a longer life expectancy generally observed in females. Few studies measured incidence rates. Further work is required to understand population characteristics with these conditions and the overlap between them. PROSPERO registration No. CRD42019153806.

Nutrition Risk, Resilience and Effects of a Brief Education Intervention among Community-Dwelling Older Adults during the COVID-19 Pandemic in Alberta, Canada

Up to two-thirds of older Canadian adults have high nutrition risk, which predisposes them to frailty, hospitalization and death. The aim of this study was to examine the effect of a brief education intervention on nutrition risk and use of adaptive strategies to promote dietary resilience among community-dwelling older adults living in Alberta, Canada, during the COVID-19 pandemic. The study design was a single-arm intervention trial with pre–post evaluation. Participants (N = 28, age 65+ years) in the study completed a survey online or via telephone. Questions included the Brief Resilience Scale (BRS), SCREEN-14, a brief poverty screen, and a World Health Organization-guided questionnaire regarding awareness and use of nutrition-related services and resources (S and R). A brief educational intervention involved raising participant awareness of available nutrition S and R. Education was offered via email or postal mail with follow-up surveys administered 3 months later. Baseline and follow-up nutrition risk scores, S and R awareness and use were compared using paired t-test. Three-quarters of participants had a high nutrition risk, but very few reported experiencing financial strain or food insecurity. Those at high nutrition risk were more likely to report eating alone, compared to those who scored as low risk. There was a significant increase in awareness of 20 S and R as a result of the educational intervention, but no change in use. The study shows increasing individual knowledge about services and resources in the community is not sufficient to change use of these services or improve nutrition risk.

Magnitude, Temporal Trends, and Inequalities in the DALYs and YLDs of Nutritional Deficiency among Older Adults in the Western Pacific Region: Findings from the Global Burden of Disease Study 1990-2019

The population in the Western Pacific region is aging rapidly. Nutritional deficiency is prevalent in older adults; however, information regarding nutritional deficiency in this population is scarce. Using the 2019 Global Burden of Disease (GBD) results, the age-standardized disability-adjusted life years (DALYs) and years of healthy life lost due to disability (YLDs) from nutritional deficiency were estimated between 1990 and 2019 for this population. Average annual percentage change (AAPC) was used to assess temporal trends, and linear mixed-effects models were used to examine socioeconomic and sex inequalities. From 1990 to 2019, the age-standardized DALYs of nutritional deficiency in this population decreased from 697.95 to 290.95 per 100,000, and their age-standardized YLDs decreased from 459.03 to 195.65 per 100,000, with the greatest declines seen in South Korea (AAPCs < −5.0). Tonga had the least decline in DALYs (AAPC = −0.8), whereas Fiji experienced an increase in YLDs (AAPC = 0.1). Being female and having a lower sociodemographic index score was significantly associated with higher age-standardized DALYs and YLDs. The magnitude and temporal trends of the nutritional deficiency burden among older adults varied across countries and sex in the region, indicating that health policies on nutritional deficiency among older adults must be crafted to local conditions.

Lifestyle Behaviors and Quality of Life Among Older Adults After the First Wave of the COVID-19 Pandemic in Hubei China

Background: Older adult quality of life (QoL) is facing huge challenges during the COVID-19 pandemic. New normal lifestyle behaviors, including getting adequate physical activity (PA), consuming sufficient fruits and vegetables (FV) and enacting individual preventive behaviors (frequent hand washing, facemask wearing, and social distancing), as a significant determinant for QoL, have not been adequately addressed in older adults during the pandemic. This study aimed to investigate the characteristics of QoL in Chinese older adults after the first wave of the COVID-19 pandemic in Hubei China. The objective of the study was to examine any associations of lifestyle behaviors with QoL, and to identify the moderating role of socioeconomic indicators in the associations identified. Methods: A cross-sectional study was conducted in Hubei, China, from June 15, 2020, to July 10, 2020. Five hundred sixteen older adults completed an online survey (mean age = 67.6 ± 6.6; 57.9% women). The questionnaire consisted of demographic information, covariates (chronic diseases and infected cases of acquaintances), lifestyle behaviors [PA stage, FV intake (FVI) stage and three preventive behaviors], and QoL. T-tests, ANOVA tests, multiple linear regression models with simple slope analyses were used to test the hypotheses. Results: QoL significantly differed in relation to economic situation, chronic diseases, marital status, education, living situation, age group, and professional status. Participants' economic situation (βaverage vs. below average = 0.17, p < 0.01; βabove average vs. below average = 0.15, p < 0.01), chronic diseases (βyes vs. no = 0.19, p < 0.001), FVI stage (β = 0.21, p < 0.001), and preventive behaviors (β = 0.10, p < 0.05) indicated a significant association with QoL. Education level and economic situation significantly interacted with preventive behaviors on QoL, respectively (βpreventive behaviors × educational level = -1.3, p < 0.01; βpreventive behaviors × economic situation = -0.97, p < 0.05). Conclusions: Findings emphasize the importance of enhancing FVI and preventive behaviors on QoL improvement in older adults during the COVID-19 pandemic. Older adults who are in a lower economic situation with lower education levels should be given priority when implementing interventions to improve preventive behaviors and QoL in older adults.

Socioeconomic Risk Factors of Poor Nutritional Status in Polish Elderly Population: The Results of PolSenior2 Study

Poor nutritional status (PNS) threatens successful aging. Identifying potentially modifiable predictors of PNS is essential for elaborating a preventive strategy for the population at risk. To assess the prevalence of PNS in the Polish elderly population and analyze its socioeconomic correlates based on the data from the nationwide PolSenior2 project. Special emphasis was put on potentially modifiable factors among the identified PNS predictors. Nutritional status was assessed in 5698 community-dwelling older adults with the Mini Nutritional Assessment-Short Form. We evaluated the effect of age, sex, level of education, marital status, place of residence, subjective loneliness, and self-reported poverty on the nutritional status of the studied subjects. PNS was found in 25.3% of studied subjects (27.7% women and 21.9% men; p < 0.001). Female sex, older age, unmarried status (in men), subjective loneliness, and self-reported poverty were independent correlates of PNS. The two last above-mentioned predictors were identified as potentially modifiable. Based on our results, we recommend preventive interventions (e.g., performing regular screening), particularly in unmarried (men), poorly educated individuals, self-reporting poverty, complaining of loneliness, and the oldest old. PNS preventive strategies should include social support (both emotional and instrumental) to reduce the effect of poverty and subjective loneliness.

Nutrition Literacy and Healthy Diet: Findings from the Validation of a Short Seniors-Oriented Screening Tool, the Spanish Myths-NL

A good level of nutrition literacy (NL) is proposed as a determinant factor for following a healthy diet. Improving seniors’ NL might be particularly pertinent to enhance the quality of their diets. This study aimed to systematically design and validate a short seniors-oriented questionnaire as a screening tool to evaluate NL. We developed the Myths-NL questionnaire, composed of 10 widespread nutrition myths, and checked for its content and face validity. An observational cross-sectional study was conducted to explore the validity and the test–retest reliability, involving a community-dwelling group of 316 individuals aged 65 years and over. Construct validity was proved by establishing both discriminant and convergent validity. Cronbach α = 0.61 and Spearman r = 0.79 (p = 0.02) demonstrated internal consistency and test–retest reliability. Participants who had secondary/university studies scored significantly higher compared with those with primary (p < 0.001), and a significant linear relationship (R2 = 0.044, p = 0.001) with a positive slope (β = 0.209) between Mediterranean Diet Adherence Screener (MEDAS) and Myths-NL scores was observed, proving construct validity. In conclusion, the Myths-NL questionnaire is a valid and reliable tool to screen NL in Spanish seniors and it might be useful as an assessment NL tool for designing and implementing lifestyle interventions to promote healthy eating.

Remaining Socially Connected at 100 and Beyond Reduces Impact of Loneliness on Nutritional Status

BACKGROUND

Understanding factors influencing centenarians' nutritional status can offer insight into effective nutrition interventions to improve quality of life among this population.

OBJECTIVE

This cross-sectional study was conducted to evaluate the role of social support and loneliness on nutritional status among Oklahoma centenarians (N = 151).

METHODS

Nutritional status was assessed with the Short Form Mini Nutrition Assessment (MNA-SF). Perceived social support was assessed with the 24-item Social Provisions Scale. Loneliness was examined with the 10-item UCLA loneliness scale.

RESULTS

Ordinal logistic regression revealed that those who lacked social support were at increased risk of poor nutritional status (OR = 2.28, p < .05). Further, the model revealed that centenarians who reported lack of social support and loneliness had almost 2.8 times higher likelihood of being at risk of poor nutritional status compared to their socially connected counterparts (p < .01).

CONCLUSIONS AND IMPLICATIONS

Findings have implications for geriatric dietitians, social workers, and clinical counselors seeking to implement services and programs aimed at helping long-lived adults feel socially connected and maintain proper nutritional well-being.

Retirement is associated with a decrease in dietary quality

BACKGROUND AND AIM

Retirement has been associated with changes in dietary intake. We evaluated dietary intake and compliance to dietary guidelines after retirement in a population-based survey.

METHODS

Data from a prospective study conducted in Lausanne, Switzerland. Dietary intake was assessed using a validated food frequency questionnaire in 2009-2012 (first survey) and 2014-2017 (second survey). Total energy intake (TEI), macro and micronutrients, foods, dietary scores and compliance to dietary guidelines were assessed. Three approaches were used comparing changes in dietary intake: 1) before and after retiring (paired analysis); 2) in participants who retired with gender- and age-matched participants who did not retire (two-group comparison), and 3) in participants who retired, who did not retire or who were retired at both surveys (analysis of variance).

RESULTS

Using the first approach, newly retired participants (n = 215) increased their intake of total (median and [interquartile range]: 15.2 [13.7-17.5] vs. 14.9 [13.3-17.1] % of TEI) and animal (11.1 [9.1-13.0] vs. 10.0 [8.5-12.6] %TEI) protein; total (35.8 [32.1-40.7] vs. 34.6 [30.0-39.1] %TEI), saturated and monounsaturated fat; alcohol; cholesterol; vitamin D and fish, and decreased their intake of vegetable protein; total carbohydrates and monosaccharides, and of the Mediterranean diet score. Those findings were confirmed for total and saturated fat, alcohol, total carbohydrates and monosaccharides; vitamin D and fish intake, and of the Mediterranean diet score in the other two approaches.

CONCLUSION

Retirement was associated with an unhealthier dietary intake.
