Characterisation of community-dwelling older adults with poor appetite

Association of oral health with nutritional status of the older adults: a cross-sectional study

OBJECTIVES

The potential association between oral health and nutritional status of the very old, has been poorly investigated. Thus, we carried out the cross-sectional study to evaluate the association of oral health with the nutritional status of the older adults.

METHODS

210 participants aged over 75 years were included in the study. Nutritional status was assessed by the Short-form Mini-Nutritional Assessment (MNA-SF) and body composition measurement. Data were available for self-reported oral health (10-item Eating Assessment Tool (EAT-10) and Chewing Function Questionnaire (CFQ)) and specific experimental tests including salivary flow, tongue and lip pressure, occlusal force, water swallow test and taste test for the detection of oral functions. Spearman rank correlation was used to analyze the correlation between body composition and oral health. Logistic regression and restricted cubic spline models were applied to examine the association of oral health with malnutrition.

RESULTS

The study reveals that poor oral health is related to the malnutrition. The tongue pressure and molar occlusal force were significantly associated with malnutrition in an L-shaped dose-response relationship after adjustment for potential confounding factors. The higher the tongue pressure and molar occlusal force, the lower the risk of malnutrition. Besides, the CFQ score, salty, sour, and bitter taste, are risk factors for malnutrition.

CONCLUSIONS

The presence of malnutrition is significantly associated with poor oral health in older adults. Our study supposes that the design of food suitable for oral conditions of the older adults may be another feasible solution to the nutritional problems among them.

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.].

Real-life intrinsic capacity screening data from the ICOPE-Care program

The Integrated Care for Older People (ICOPE) program is a healthcare pathway that uses a screening test for intrinsic capacity (IC) as its entry point. However, real-life data informing on how IC domains cluster and change over time, as well as their clinical utility, are lacking. Using primary healthcare screening data from more than 20,000 French adults 60 years of age or older, this study identified four clusters of IC impairment: 'Low impairment' (most prevalent), 'Cognition+Locomotion+Hearing+Vision', 'All IC impaired' and 'Psychology+Vitality+Vision'. Compared to individuals with 'Low impairment', those in the other clusters had higher likelihood of having frailty and limitations in both activities of daily living (ADL) and instrumental activities of daily living (IADL), with the strongest associations being observed for 'All IC impaired'. This study found that ICOPE screening might be a useful tool for patient risk stratification in clinical practice, with a higher number of IC domains impaired at screening indicating a higher probability of functional decline.

Underweight, overweight, and weight change in older family caregivers and their care recipients: longitudinal evidence from a randomized controlled trial

This study aimed to identify differences among body mass index (BMI) categories of older family caregivers (≥60 years) and their care recipients (≥65 years). Secondly, this study aimed to examine group differences and factors associated with weight change during a nutrition and oral health intervention. This secondary analysis of a randomized controlled trial (ClinicalTrial.gov (NCT04003493)) involved individually tailored nutritional guidance from a clinical nutritionist and oral health guidance from a dental hygienist. Baseline BMI differences were analyzed, followed by further analyses of group differences and associated factors of weight change over a 6-month period using generalized estimating equations. Among the participants (113 family caregivers and 107 care recipients), 36.3% and 35.1% were overweight (BMI >29 kg/m2), while 18.6% and 21.6% were underweight (BMI <24 kg/m2) at baseline, respectively. For family caregivers differences in BMI categories included age, mid-arm and calf circumferences, and plasma prealbumin concentration. For care recipients differences were observed in medication use, mid-arm and calf circumferences, Mini Nutritional Assessment scores, physical function, and number of teeth. During the 6-month intervention, there were no differences in weight change between intervention and control groups for both caregivers and care recipients. Factors significantly associated (p < 0.05) with weight loss included female sex for both caregivers and care recipients, and frailty for caregivers. Family caregivers' characteristics were not significantly associated with weight change in their care recipients. In conclusion, being overweight is a prevalent among older family caregivers and care recipients. Factors such as age, medication use, physical function, number of teeth, and Mini Nutritional Assessment scores varied across BMI categories. Female sex was associated with weight loss in both older family caregivers and care recipients, and frailty was associated with weight loss in caregivers. However, the characteristics of family caregivers did not explain the weight loss of their care recipients. Clinical Trial Registration: [https://www.ClinicalTrial.gov/], identifier [NCT04003493].

Oral frailty, appetite and dietary variety in late-stage older adults: A cross-sectional study (the STudy of lAte-stage oldeR adulTs in Tottori; START Tottori)

AIM

Efforts to combat frailty and preserve good health in older adults have highlighted oral frailty as an early indicator of overall frailty. Individuals showing oral frailty are at an elevated risk of insufficient nutritional intake compared with those without oral frailty; however, underlying mechanisms remain poorly explored. In this cross-sectional study, we aimed to examine the link between oral frailty and undernutrition, especially regarding poor appetite and low dietary diversity.

METHODS

The analysis included 2727 late-stage older adults (mean age 79.9 ± 4.3 years) who underwent dental checkups in a prefecture in Japan from 2016 to 2020. The examination involved a questionnaire survey (covering basic information, frailty screening index, appetite index: Simplified Nutritional Appetite Questionnaire; and dietary variety: Dietary Variety Score) and a measurement survey (including intraoral confirmation, oral diadochokinesis and masticatory efficiency test). Individuals with three or more indications of poor oral function, identified through oral function assessment, were defined as showing oral frailty. Binomial logistic regression and path analyses examined associations among oral frailty, Simplified Nutritional Appetite Questionnaire and Dietary Variety Score.

RESULTS

Among those analyzed, 1208 (44.3%) participants were categorized into the oral frailty group. Binomial logistic regression analysis showed that Simplified Nutritional Appetite Questionnaire (odds ratio for oral frailty per 1-point increase 0.88, 95% confidence interval 0.84-0.93) and Dietary Variety Score (odds ratio 0.95, 95% confidence interval 0.92-0.98) were significantly associated with oral frailty. The path analysis showed individual associations between each examined factor.

CONCLUSIONS

Oral frailty was associated with decreased appetite and dietary variety in late-stage older adults. Geriatr Gerontol Int 2024; 24: 626-633.

Dietary characteristics of community-dwelling older adults with poor appetite: a cross-sectional analysis

RATIONALE

Poor appetite is considered a key factor in the development of malnutrition, a link that can be explained by alterations in dietary intake. Given the limited data on dietary characteristics in community-dwelling older adults with poor appetite, the present study aimed to examine whether poor appetite is associated with lower nutrient intake and more unfavourable food choices.

METHODS

In 569 participants of the Longitudinal Aging Study Amsterdam aged ≥70 years appetite was assessed using the Simplified Nutritional Appetite Questionnaire and dichotomised into normal (>14) and poor (≤14). Intake of energy, 19 nutrients, 15 food groups, the Dutch Healthy Diet Index 2015 (DHD15) and Mediterranean Diet Score (MDS) were calculated from a food frequency questionnaire. Dietary differences between appetite groups were examined using Mann-Whitney U test and binary logistic regression adjusted for potential confounders.

RESULTS

Mean age was 78 ± 6 years and 52% were female. Appetite was poor in 12.5% of participants. Energy intake was 1951 (median; quartiles 1-3: 1,653-2,384) kcal/day with no difference between appetite groups. Poor appetite was associated with lower intake of protein (OR 0.948, 95%CI 0.922-0.973), folate (0.981, 0.973-0.989), zinc (0.619, 0.454-0.846), vegetables (0.988, 0.982-0.994) and lower scores of DHD15 (0.964, 0.945-0.983) and MDS (0.904, 0.850-0.961), as well as higher intake of carbohydrates (1.015, 1.006-1.023), and vitamins B2 (4.577, 1.650-12.694) and C (1.013, 1.005-1.021).

CONCLUSIONS

Community-dwelling older adults with poor appetite showed poorer diet quality with a lower intake of protein, folate, zinc and vegetables, compared with those reporting normal appetite and should be advised accordingly.

Appetite and family and friends network among community-dwelling older adults: A cross-sectional study

OBJECTIVES

The aim of this study was to investigate the stronger correlate of appetite-family or friend networks-in community-dwelling older adults, given that undernutrition can impair physical function, increase mortality, and be influenced by social networks.

METHODS

A cross-sectional study was conducted in Kasugai City, Aichi Prefecture, and Nara City, Nara Prefecture, Japan, between August 2019 and March 2023. The analysis included 119 participants (women: 79%, mean age: 76.5 ± 5.6 y). A multiple regression analysis was performed, using the scores from the Japanese version of the Simplified Nutritional Appetite Questionnaire (SNAQ-J) as the dependent variable and family network and friend network as the independent variables. The analysis included social participation, living alone status, sex, age, body mass index, skeletal muscle mass index, grip strength, walking speed, and the Japanese version of the 15 Geriatric Depression Scale score as covariates to examine their relationship with appetite.

RESULTS

The mean value of the SNAQ-J score of the participants was 15.4 ± 1.2. Seven participants (6%) had a loss of appetite. Family network was significantly associated with appetite (B = 0.121, β = 0.266, P <0.05; 95% condidence interval [CI], 0.030-0.212). In the single regression analysis, the friend network was significantly associated with the total score of the SNAQ-J (B = 0.115, P <0.001; 95% CI, 0.052-0.177); however, this association was not observed in the multiple regression analysis (B = 0.002, β = 0.006, P = 0.954; 95% CI, -0.074-0.078).

CONCLUSION

Appetite was associated with family networks. Among social networks, focusing on family networks may help prevent the loss of appetite in older adults in Japan.

The associations between sleep quality, mood, pain and appetite in community dwelling older adults: a daily experience study

OBJECTIVES

To investigate the daily life experiences of sleep, mood, and pain in relation to appetite in community-dwelling older adults aged 75 years and older, stratified by sex.

DESIGN

Existing data from a daily experience study embedded in the Longitudinal Aging Study Amsterdam (LASA) among the oldest-old (≥75 years).

SETTING

LASA is an ongoing cohort study of a nationally representative sample of older adults aged ≥55 years from three culturally distinct regions in the Netherlands.

PARTICIPANTS

434 community-dwelling older adults aged ≥75 years.

MEASUREMENTS

Participants filled-out a one-week diary on daily experience of pain, mood, last night sleep (10-point Likert scale), and appetite (5-point Likert scale) on five measurement occasions between 2016 and 2021. (Hybrid) linear mixed models were used to investigate overall, within-subject and between-subject association between mood, sleep, and pain (independent variables) and appetite (dependent variable), while correcting between-subject associations for season, age, educational level, partner status, body mass index, alcohol consumption, physical activity level, smoking status, chronic diseases and use of nervous system medication, stratified by sex.

RESULTS

Averaged over all days, males reported a poor appetite on 12% of the days and females on 19% of the days. Statistically significant between-subject associations with a poorer appetite were found for lower mood (unstandardized b = 0.084 [95% CI 0.043-0.126] (males), (b = 0.126 [95% CI 0.082-0.170] (females)), poorer sleep (b = 0.045 [95% CI 0.007-0.083] (males), (b = 0.51 [95% CI 0.017-0.085] (females)) and more severe pain in males only (b = 0.026 [95% CI 0.002-0.051]). Except for pain, within-subject associations were somewhat weaker: mood: b = 0.038 [95% CI 0.016-0.060] (males), (b = 0.082 [95% CI 0.061-0.104] (females)); sleep: b = 0.029 [95% CI 0.008-0.050] (males), (b = 0.15 [95% CI 0.005-0.025] (females)); and pain (b = 0.032 [95% CI 0.004-0.059] (males)).

CONCLUSIONS

This study found that poor sleep, low mood (more strongly in females) and more severe pain (males only) are associated with poor appetite in older adults on a daily level both within and between persons. Sex differences in factors related to poor appetite should be considered in future research.

Poor Appetite in Frail Older Persons-A Systematic Review

Anorexia of aging is a common problem in older adults. Depending on the setting, its prevalence varies from about 10% (among community-dwelling older adults) to over 30% in acute wards and nursing homes. The objective of this systematic review was to establish the prevalence of poor appetite in frail persons ≥60 years of age. We performed a literature search for studies where the prevalence of anorexia of aging among frail and pre-frail old adults was reported. 957 articles on this topic were identified. After eligibility assessment, three articles were included in the review. The studies included 4657 community-dwelling older adults. The weighted total prevalence of anorexia of aging in all the included studies was 11.3%. Among frail and pre-frail participants, loss of appetite was reported in 20.5% (weighted estimate). Overall, robust status was associated with a 63% lower probability of concomitant anorexia of ageing (OR 0.37, 95%CI 0.21-0.65, p = 0.0005). Frailty or risk of frailty are associated with more prevalent anorexia of ageing. This has potential practical implications; however, more research, especially to elucidate the direction of the relation, is needed.
