Current Evidence on the Association of Micronutrient Malnutrition with Mild Cognitive Impairment, Frailty, and Cognitive Frailty among Older Adults: A Scoping Review

Association of whole blood multi-micronutrients with mild cognitive impairment in Chinese older adults: a matched case-control study

PURPOSE

Adequate micronutrients play a crucial role in cognitive health. Identifying relevant micronutrients and constructing risk prediction models can guide the prevention of mild cognitive impairment (MCI) in older adults. This study aimed to assess the associations of MCI with whole blood micronutrient levels and develop a nomogram for personalized MCI risk prediction in older adults.

METHODS

In the matched case-control study, 100 MCI patients and 100 matched controls by age, sex and education from Baodi District, Tianjin, China were recruited. MCI was determined by a modified version of the Petersen criteria. Whole blood levels of 9 vitamins and 5 minerals were measured using the dried blood spot technique. Weighted quantile sum regression was employed to identify the most significant micronutrients associated with cognitive function. Receiver operating characteristic (ROC) curves were constructed, and a nomogram for predicting MCI risk was developed.

RESULTS

High levels of vitamins (vitamin A, vitamin B2, vitamin B6, vitamin B9) and minerals (magnesium, selenium) were significantly associated with lower MCI prevalence, in which vitamin B2, vitamin B9 and selenium were ranked as the most significant contributors to cognitive function. The ROC curves for vitamin B2 and vitamin B9 (area under the curve = 0.855) have superior diagnostic accuracy compared to individual assessments (p < 0.05). Based on these findings, a nomogram was developed using these two micronutrients to predict MCI risk.

CONCLUSION

The nomogram based on vitamin B2 and vitamin B9 can be effectively used to detect MCI early and guide preventive strategies in older adults.

Effects of comprehensive intervention models on cognitive frailty in community-dwelling older adults: A 12-month follow-up study

BACKGROUND

Cognitive frailty (CF) is of concern because of its high prevalence in older population and its close association with adverse health outcomes. However, interventions against CF in China are relatively simple. Therefore, the purpose of this study was to analyse the effects of comprehensive interventions on CF in community-dwelling older adults.

METHODS

225 participants, including 108 individuals with reversible CF (RCF) and 117 individuals with potentially RCF (PRCF) were recruited and divided into intervention and control groups. Participants in RCF Intervention Group underwent primary intervention, and participants in PRCF Intervention Group underwent secondary intervention. CF reversal rate and MoCA score were recorded.

RESULTS

Primary intervention and secondary intervention could well reversed CF. Additionally, MoCA scores changed significantly.

CONCLUSIONS

Adhering to regular comprehensive interventions can effectively reverse CF for community-dwelling older adults. Additionally, RCF maybe is an effective target for reversing CF via early intervention.

Translation and Validation of the Chinese Version of the Rapid Geriatric Assessment (C-RGA): A Screening Tool for Geriatric Syndromes in Nursing Home Residents

Background: Frailty, sarcopenia, nutritional risk, and cognitive impairment are prevalent geriatric syndromes that adversely affect health outcomes in older adults, underscoring the need for an effective screen tool to enable early detection and timely intervention. Methods: This study employed a cross-sectional validation design and translated, culturally adapted, and validated the Chinese version of the Rapid Geriatric Assessment (C-RGA) among 416 nursing home residents. The C-RGA consists of four subscales: the simple frail questionnaire screening tool (FRAIL), SARC-F for sarcopenia (SARC-F), the Simplified Nutritional Assessment Questionnaire (SNAQ), and the Rapid Cognitive Screen (RCS). Results: The C-RGA demonstrated high content validity (S-CVI/Ave = 0.982) and strong internal consistency (Cronbach's α = 0.839). Factor analysis confirmed its four-domain structure, accounting for 61.497% of the variance. Model fit indices demonstrated good construct validity (χ2/df = 1.122, RMSEA = 0.024, GFI, AGFI, and CFI > 0.90), supporting the robustness of the assessment tool. Pearson correlation analysis revealed a strong association between FRAIL and SARC-F with SNAQ (r = -0.671, 95% CI: [-0.742, -0.600], p < 0.01) and a moderate correlation with RCS (r = -0.426, 95% CI: [-0.513, -0.339], p < 0.01), underscoring the interplay among nutritional deficits, muscle weakness, and cognitive impairment. Conclusions: The C-RGA demonstrates strong psychometric properties, supporting its potential use as a screening tool for the early detection of frailty, sarcopenia, nutritional risk, and cognitive impairment among nursing home residents, enabling timely and targeted interventions. Future research should further assess its applicability across diverse healthcare settings to enhance its generalizability and clinical utility.

Association of a novel nutritional index with cognitive impairment in middle-aged and elderly Chinese adults: a cross-sectional analysis from the China Health and Retirement Longitudinal Study

Purpose

The triglyceride-cholesterol-body weight index (TCBI), a novel and easily computable nutritional index, incorporates serum triglyceride (TG), total cholesterol (TC), and body weight (BW). This study explored the association between TCBI and cognitive impairment in middle-aged and elderly Chinese populations.

Patients and methods

This cross-sectional study employed data from the China Health and Retirement Longitudinal Study (CHARLS) baseline survey, including 7,145 participants. TCBI was calculated as TG (mg/dL) × TC (mg/dL) × BW (kg)/1,000. Cognitive function was assessed based on mental status and episodic memory, with a total score below 11 indicating cognitive impairment. The relationship between TCBI and cognitive impairment was examined using multiple logistic regression, smooth curve fitting, and subgroup analyses.

Results

After full adjustment, each 1-unit increase in log-transformed TCBI (Lg TCBI) was associated with a 29.7% reduction in cognitive impairment risk [odds ratio (OR) = 0.703, 95% confidence interval (CI): 0.529-0.933; p = 0.015]. When Lg TCBI was categorized into quartiles, the Q2, Q3, and Q4 groups exhibited a reduced risk of cognitive impairment by 19.9, 16.3, and 22.9%, respectively (p for trend = 0.043), compared to the Q1 group. Smooth curve fitting revealed a consistent decrease in cognitive impairment risk with higher Lg TCBI levels. Subgroup analysis indicated that the association was stronger among participants aged ≥60 years (OR = 0.655, 95% CI: 0.438-0.979), non-current drinkers (OR = 0.643, 95% CI: 0.451-0.917), and those who engaged in socializing (OR = 0.568, 95% CI: 0.371-0.871).

Conclusion

TCBI was significantly and negatively associated with cognitive impairment in Chinese middle-aged and elderly individuals, with the effect more pronounced in those aged ≥60 years, non-current drinkers, and socially active participants.

The Psychological, Cognitive, and Behavioural Effects of Starvation in Humans: A Scoping Review

BACKGROUND

Research has highlighted the physical complications of starvation, but there is less research examining the psychological effects of starvation in humans.

AIMS

This scoping review synthesises literature on the non-physical effects of starvation in humans.

METHOD

Following PRISMA-ScR guidelines, we searched MEDLINE, PsycINFO, and Global Health for studies published between 1946 and 2023 examining the non-physical effects of starvation in individuals aged 2-79 years, including those who were starved, malnourished, stunted, wasted, underweight, had a restrictive eating disorder, or were raised in famine conditions.

RESULTS

From 16,555 abstracts, 851 articles on the effects of malnutrition were reviewed, and 318 were included. Among these, 35% focused on children and adolescents, 25.5% on adults with comorbid illnesses, 17% on older adults, 13% on those with eating disorders, 6% on adults without comorbidities, and 3.5% on famine survivors. Cognitive impairments were the most frequently reported effects in children. In adults and older adults, depression and anxiety were common, along with reduced cognitive functioning, reduced quality of life, social withdrawal, impaired sleep and impaired sexual functioning. Individuals with eating disorders experienced depression, anxiety, obsessive-compulsive symptoms, emotion regulation difficulties, and cognitive impairment.

CONCLUSIONS

There is extensive evidence showing the detrimental non-physical consequences of starvation in children and adults. These findings should inform research, clinical interventions, and educational materials addressing the effects of insufficient nutrition, including in those with restrictive eating disorders.

Knowledge, attitudes and practices of healthcare professionals in the management of patients with hypertension and concurrent bronchial asthma: a cross-sectional study in the Yellow River Delta region of China

OBJECTIVE

To assess the Knowledge, Attitudes and Practices (KAP) among healthcare professionals in managing patients with coexisting hypertension and bronchial asthma.

DESIGN

A cross-sectional survey. The reporting of this study followed the Strengthening the Reporting of Observational Studies in Epidemiology checklist.

SETTING

From 30 March to 15 April 2024 at 66 various level hospitals and community health service centres.

PARTICIPANTS

Physicians and nurses specialising in clinical internal medicine, each with over 2 years of practice and who provided informed consent.

PRIMARY AND SECONDARY OUTCOME MEASURES

The demographic characteristics of the healthcare professionals and their KAP towards the Management of Patients with Hypertension and Concurrent Bronchial Asthma were collected using a self-administered questionnaire. The primary outcome was the KAP scores. The secondary outcomes were the factors associated with the KAP scores and how the KAP dimensions interacted among them.

RESULTS

The study involved 586 valid questionnaires collected from participants. Participants' median KAP scores were as follows: knowledge - 8 (IQR: 6-9), attitude - 31 (29-34) and practice - 41 (36-46) on scales ranging from 0 to 12, 7 to 35 and 12 to 60, respectively. Multivariate logistic regression analysis showed having a Bachelor's degree or higher education (OR=0.614; 95% CI (0.421, 0.896); p=0.011), and a knowledge score ≥8 (OR=2.130; 95% CI (1.527, 2.973); p<0.001) significantly predicted adherence to recommended practices. Structural equation modelling revealed significant direct effects between knowledge and attitude (β=0.578, p=0.010) and between knowledge and practice (β=0.221, p=0.010). However, the direct link between attitude and practice (β=0.162, p=0.052) and indirect effect of knowledge on practice via attitude (β=0.094, p=0.052) were not statistically significant.

CONCLUSIONS

Healthcare professionals exhibited limited knowledge, positive attitudes but suboptimal practices when managing patients with comorbid hypertension and bronchial asthma. It is crucial to develop targeted educational interventions and continuous professional development programmes to improve clinical outcomes in this patient population.

Progress in lung cancer study coupled with cognitive frailty in elderly individuals

Cognitive frailty is increasingly prevalent among elderly patients, heightening the risks of dementia, disability, and mortality. This demographic also faces a rising incidence of lung cancer, and cognitive frailty complicates rehabilitation efforts. Research on cognitive frailty in elderly lung cancer patients is still emerging. This review examines the definition and assessment of cognitive frailty, its the current prevalence in this population, and nursing management strategies. While tools for assessing cognitive frailty are not standardized, the incidence remains high, leading to adverse health outcomes. Comprehensive interventions for elderly lung cancer patients with cognitive frailty are insufficient, highlighting the need for more effective strategies to mitigate this issue. The goal is to enhance both research and clinical practices in identifying and diagnosing cognitive frailty in this vulnerable population.

Understanding exogenous factors and biological mechanisms for cognitive frailty: A multidisciplinary scoping review

Cognitive frailty (CF) is the conjunction of cognitive impairment without dementia and physical frailty. While predictors of each element are well-researched, mechanisms of their co-occurrence have not been integrated, particularly in terms of relationships between social, psychological, and biological factors. This interdisciplinary scoping review set out to categorise a heterogenous multidisciplinary literature to identify potential pathways and mechanisms of CF, and research gaps. Studies were included if they used the definition of CF OR focused on conjunction of cognitive impairment and frailty (by any measure), AND excluded studies on specific disease populations, interventions, epidemiology or prediction of mortality. Searches used Web of Science, PubMed and Science Direct. Search terms included "cognitive frailty" OR (("cognitive decline" OR "cognitive impairment") AND (frail*)), with terms to elicit mechanisms, predictors, causes, pathways and risk factors. To ensure inclusion of animal and cell models, keywords such as "behavioural" or "cognitive decline" or "senescence", were added. 206 papers were included. Descriptive analysis provided high-level categorisation of determinants from social and environmental through psychological to biological. Patterns distinguishing CF from Alzheimer's disease were identified and social and psychological moderators and mediators of underlying biological and physiological changes and of trajectories of CF development were suggested as foci for further research.

Associations between Cognitive Impairment, Weight Status and Comorbid Conditions in Hospitalized Adults of 55 Years and Older in Guadeloupe

Cognitive decline and comorbid conditions commonly co-occur, and these conditions can affect cognitive health. We aimed to estimate the prevalence of cognitive impairment (CI) according to weight status and to evaluate the associations between CI, weight status and comorbid conditions in adults of 55 years and older. The Abbreviated Mental Test Score (AMTS) was used. Logistic regressions were performed. Overall, 415 individuals were included. The mean age was 75.7 ± 10.1 years, and the mean BMI was 26.2 ± 6.9 kg/m2. The prevalence of CI was 20.7% in the whole study group and 31%, 24.8%, 17.7% and 10.2% in underweight, normal weight, overweight and obese individuals, respectively; p < 0.004. The low folate, vitamin D and prealbumin levels were more frequently found in individuals with CI compared with those without CI. Compared with the obese individuals, a higher odds ratio of prevalent CI was noted for underweight individuals OR 3.89 (95% CI 1.54-9.80); p = 0.004. Additionally, male gender, older age, stroke, having three or more comorbid conditions and findings of undernutrition were significantly associated with CI. Being underweight was associated with an increased risk of CI. Prevention strategies including the monitoring of nutritional status may help to prevent cognitive decline and promote healthy aging.

The association between frailty biomarkers and 20-year all-cause and cardiovascular mortality among community-dwelling older adults

OBJECTIVES

While several biomarkers were previously associated with frailty and mortality, data are still contradicting. We aimed to evaluate the association between novel biomarkers and frailty among community-dwelling older adults to enhance understanding of the pathophysiology of frailty.

METHODS

Nine hundred and sixty-three older adults were screened during the third phase (1999-2008) of the Israel study on Glucose Intolerance, Obesity, and Hypertension (GOH). Frailty was defined as sedentary individuals, past 10 years hospitalizations, or at least one of the following: body mass index (BMI) <21 kg/m2; albumin <3.2 g/dl; ≥2 major baseline diseases. Biomarkers were evaluated for their association with frailty, all-cause, and cardiovascular mortality.

RESULTS

Mean baseline age was 72 ± 7 years, 471 (49%) were women, and 195 (20%) were classified as frail. Median follow-up for cardiovascular and all-cause mortality was 11 and 13 years, with 179 (18.6%) and 466 (48.4%) deaths recorded, respectively. Multivariable logistic regression showed greater odds for frailty with lower quartile of alanine aminotransferase (ALT) (OR = 1.8, 95%CI: 1.2-2.8, p = 0.01), and for each 5 µmol/L increment in homocysteine levels (OR = 1.3, 95%CI: 1.1-1.5, p = 0.001). Multivariate Cox regression showed greater all-cause and cardiovascular mortality risk for individuals with low ALT (HR = 1.6, 95%CI: 1.3-2.0, p < 0.001 and HR = 1.5, 95% CI: 1.0-2.2, p = 0.03, respectively), and high homocysteine (HR = 1.1, 95%CI: 1.1-1.3, p = 0.003 and HR = 1.2, 95%CI: 1.0-1.3, p = 0.04, respectively). Homocysteine association with mortality was more pronounced in those with baseline ischemic heart disease (IHD) compared with subjects free of IHD (P for interaction = 0.01).

CONCLUSIONS

Lower ALT and higher homocysteine were associated with frailty, all-cause and cardiovascular mortality. These available and low-cost biomarkers underscore the nutritional and metabolic aspects of frailty when screening high-risk older adults, especially those with IHD, and may be considered as preferable screening biomarkers to be tested among these individuals for frailty and mortality risk.

Leveraging data science and machine learning for urban climate adaptation in two major African cities: a HE2AT Center study protocol

INTRODUCTION

African cities, particularly Abidjan and Johannesburg, face challenges of rapid urban growth, informality and strained health services, compounded by increasing temperatures due to climate change. This study aims to understand the complexities of heat-related health impacts in these cities. The objectives are: (1) mapping intraurban heat risk and exposure using health, socioeconomic, climate and satellite imagery data; (2) creating a stratified heat-health forecast model to predict adverse health outcomes; and (3) establishing an early warning system for timely heatwave alerts. The ultimate goal is to foster climate-resilient African cities, protecting disproportionately affected populations from heat hazards.

METHODS AND ANALYSIS

The research will acquire health-related datasets from eligible adult clinical trials or cohort studies conducted in Johannesburg and Abidjan between 2000 and 2022. Additional data will be collected, including socioeconomic, climate datasets and satellite imagery. These resources will aid in mapping heat hazards and quantifying heat-health exposure, the extent of elevated risk and morbidity. Outcomes will be determined using advanced data analysis methods, including statistical evaluation, machine learning and deep learning techniques.

ETHICS AND DISSEMINATION

The study has been approved by the Wits Human Research Ethics Committee (reference no: 220606). Data management will follow approved procedures. The results will be disseminated through workshops, community forums, conferences and publications. Data deposition and curation plans will be established in line with ethical and safety considerations.

Learning motivation and self-assessment in health economics: a survey on overconfidence in healthcare providers

INTRODUCTION

Lifelong learning is the foundation for professionals to maintain competence and proficiency in several aspects of economy and medicine. Until now, there is no evidence of overconfidence (the belief to be better than others or tested) and clinical tribalism (the belief that one's own group outperforms others) in the specialty of health economics. We investigated the hypothesis of overconfidence effects and their relation to learning motivation and motivational patterns in healthcare providers regarding healthcare economics.

METHODS

We conducted a national convenience online survey of 116 healthcare workers recruited from social and personal networks to detect overconfidence effects and clinical tribalism and to assess learning motivation. Instruments included self-assessments for five learning dimensions (factual knowledge, skills, attitude, problem-solving and behaviour) and a four-item situational motivation scale. The analysis comprised paired t-tests, correlation analyses and two-step cluster analyses.

RESULTS

We detected overplacement, overestimation and signs of clinical tribalism. Responders in the physician subgroup rated themselves superior to colleagues and that their professional group was superior to other professions. Participants being educators in other competencies showed high overconfidence in health economics. We detected two groups of learners: overconfident but motivated persons and overconfident and unmotivated learners. Learning motivation did not correlate with overconfidence effects.

DISCUSSION

We could show the presence of overconfidence in health economics, which is consistent with studies in healthcare and the economy. The subjective perception of some medical educators, being role models to students and having a superior 'attitude' (eg, morality) concerning the economy may foster prejudice against economists as students might believe them. It also may aggravate moral distress and disrupts interactions between healthcare providers managers and leaders. Considering the study's limitations, lifelong interprofessional and reflective training and train-the-trainer programmes may be mandatory to address the effects.

Malnutrition Prevalence and Nutrient Intakes of Indonesian Older Adults in Institutionalized Care Setting: A Systematic Review of Observational Studies

INTRODUCTION

Data on the prevalence of malnutrition and nutrient intakes among Indonesian older adults in institutionalized care setting are scattered and scarce. Thus, we conducted a systematic review of published and gray literature to estimate (1) the prevalence of malnutrition, (2) the level and distribution of habitual energy and nutrient intakes, and (3) the prevalence of inadequacy of energy and nutrient intakes among hospitalized and institutionalized older adults in Indonesia.

METHODS

This systematic review was written following the PRISMA 2020 checklist. The population of this review was Indonesian older adults in institutionalized care settings, including hospital wards, orphanages, nursing homes, residential facilities, and rehabilitation centers. Malnutrition was assessed using body mass index, the Mini Nutritional Assessment (MNA) score, or the subjective global assessment (SGA) score. The dietary intakes (from food recalls, food records, or food frequency questionnaire) were compared with the Indonesian Recommended Dietary Allowances for people aged 65-80. The prevalence of inadequacy was calculated using two-thirds of the Recommended Dietary Allowance as a proxy for the estimated average requirement.

RESULTS

The search yielded 330 studies from electronic databases, resulting in fifteen eligible studies. One report was obtained from an unpublished study. Based on the JBI criteria, most studies had low risk of bias and represented the target population. The prevalence of malnutrition in hospital, nursing home, and other institutionalized care ranged from 6.5% to 48.3% in hospitals and 3.2% to 61.0% in other institutionalized care units. In the hospital setting, there was a high prevalence of inadequacies for all nutrients, particularly protein (20%), calcium (more than 90%), and vitamin D intakes (more than 50%). In nursing homes, these proportions were exceptionally high for protein (66%) and calcium and vitamin D intakes (almost 100%).

CONCLUSION

The high risk of malnutrition in Indonesian older adults in institutionalized care setting is pronounced, along with poor intakes of macronutrients and micronutrients in both settings.

Consideration and Assessment of Patient Factors When Selecting an Inhaled Delivery System in COPD

Because guidelines and strategies for pharmacologic treatment of COPD focus on specific classes of inhaled medications, there is an unmet need for information to guide health care professionals for selecting an inhaled medication delivery system that matches the unique characteristics of individual patients. This article provides guidance for selecting an inhaled medication delivery system based on three "key" patient factors: cognitive function, manual dexterity/strength, and peak inspiratory flow. In addition, information is provided about specific tests to assess these patient factors. Cognitive impairment with an estimated prevalence of 25% among patients with COPD adversely affects patients' ability to correctly use a handheld device. To our knowledge, the prevalence of impaired manual dexterity/strength has not been reported in those with COPD. However, 79% of patients with COPD have reported one or more physical impediments that could influence their ability to manipulate an inhaler device. The measurement of peak inspiratory flow against the simulated resistance (PIFr) of a dry powder inhaler establishes whether the patient has the inhalation ability for creating optimal turbulent energy within the device. A suboptimal PIFr for low to medium-high resistance dry powder inhalers has been reported in 19% to 84% of stable outpatients with COPD. Health care professionals should consider cognitive function, manual dexterity/strength, and PIFr in their patients with COPD when prescribing inhaled pharmacotherapy. Impairments in these patient factors are common among those with COPD and can affect the individual's competency and effectiveness of using inhaled medications delivered by handheld devices.

Relationship of Low Vitamin B6 Status with Sarcopenia, Frailty, and Mortality: A Narrative Review

Marginal vitamin B6 (B6) deficiency is a widespread global concern. Inadequate B6 levels have been linked to an increased risk of age-related chronic diseases such as cardiovascular diseases and cancers. In recent years, the growing concern over sarcopenia (the age-related loss of muscle mass and strength) and frailty (a decline in physiological resilience and increased vulnerability associated with aging) is particularly relevant due to the emergence of super-aged societies in developed countries. Notably, among the thirty-one studies included in this review, twenty-five showed a significant association of B6 status with sarcopenia, frailty, and all-cause mortality in adults (p < 0.05), while six showed no association. Emerging studies have suggested novel mechanisms underlying this association. These mechanisms involve P2X7 receptor-mediated NLRP3 inflammasome signaling, AMPK signaling, PD-L1 signaling, and satellite cell-mediated myogenesis. Furthermore, the modulation of PLP-dependent enzymes due to B6 deficiency is associated with impaired metabolic processes, affecting energy utilization, imidazole peptide production, and hydrogen sulfide production, as well as the kynurenine pathway, all of which play vital roles in skeletal muscle health and pathophysiology. This narrative review provides an up-to-date assessment of our current understanding of the potential role of nutritional B6 status in combating sarcopenia, frailty, and mortality.

Effect of dietary supplementation with multinutrient soy flour on body composition and cognitive function in elderly individuals at the risk of low protein: a randomized, double-blind, placebo-controlled study

Insufficient protein intake and cognitive decline are common in older adults; however, there have been few studies on low protein risk screening and complex nutrient interventions for elderly individuals in rural communities. This study aimed to evaluate the effect of dietary multinutrient soy flour (MNSF) on body composition and cognitive function in elderly individuals who are at risk of protein deficiency in a randomized, double-blind, placebo-controlled clinical trial. Nutritional interventions were given to those found to have low protein levels using bioelectrical impedance analysis (BIA). Among 733 older adults screened, 62 participants were included and randomly assigned into two groups, one taking soy flour and the other taking MNSF for 12 weeks. A previous cross-sectional survey found that 35.1% of the elderly people with an average age of 71.61 ± 5.94 years had an inadequate body protein mass proportion. After the intervention, the MNSF group demonstrated a significant improvement in protein mass, muscle mass, mineral levels, skeletal muscle mass, and fat-free mass compared with baseline (all P < 0.05), as well as a better upward trend compared with the soy flour group (P = 0.08; P = 0.07; P = 0.05; P = 0.08; P = 0.07). Regarding the mini-mental state examination (MMSE) scores, the MNSF group showed a significant decrease after 12 weeks (P < 0.05), which were significantly different compared with the soy flour group (P < 0.05). In the future, the application of MNSF as a food-based supplement to improve nutrition and delay cognitive decline in older adults at the risk of protein deficiency may be considered.

Malnutrition, Depression, Poor Sleep Quality, and Difficulty Falling Asleep at Night Are Associated with a Higher Risk of Cognitive Frailty in Older Adults during the COVID-19 Restrictions

The COVID-19 restrictions, such as social isolation and disruption of daily routines, can have detrimental effects, including increased stress, anxiety, sleep disturbance, and physical and cognitive decline among older adults. This study aimed to examine the association between nutritional status, depression, sleep quality, falling asleep at night, and cognitive frailty (CF) among older Thai adults during the COVID-19 pandemic. This cross-sectional study included 408 older adults with an average age of 70.54 (5.49) years. CF was determined using Fried's frailty phenotype and the Montreal Cognitive Assessment Basic. The Mini Nutritional Assessment-Short Form, Pittsburgh Sleep Quality Index, and geriatric depression assessment were used for assessment. Multiple logistic regression analysis demonstrated that participants who were malnourished (OR 3.786; 95%CI 1.719-8.335), depressed (OR 5.003; 95%CI 2.399-10.434), had poor sleep quality (OR 1.613; 95%CI 1.041-2.500), and engaged in difficulty falling asleep (OR 1.809; 95%CI 1.022-3.203) had a higher risk of CF compared to those who did not exhibit these factors. Therefore, malnutrition, depression, poor sleep quality, and difficulty falling asleep were identified as risk factors for CF among older adults in Thailand linked to the impact of the COVID-19 pandemic. It is crucial to develop interventions to prevent CF resulting from the mentioned variables.
