Relationship between frailty, nutrition, body composition, quality of life, and gender in institutionalized older people

Association of metabolic syndrome and frailty with postoperative complications in older gastric cancer patients: A body composition perspective

OBJECTIVES

To compare the characteristics of body compositions between metabolic syndrome (MetS) and frailty, and determine the independent and overlapping of MetS and frailty with postoperative complications among older patients with gastric cancer.

DESIGN

A prospectively observational study.

SETTING AND PARTICIPANTS

Two hundred and eighty six older patients from 60 to 80 years undergoing radical gastrectomy for the first time.

MEASUREMENTS

MetS was diagnosed by the criteria from the 2020 edition of Chinese guideline for the prevention and treatment of type 2 diabetes mellitus, and frailty was defined by frailty phenotype. An InBody770 impedance analyzer was used to measure body compositions and with 10 fat- and muscle-related indicators being included in this study. Based on the presence of frailty and MetS, patients were divided into the frailty group, MetS group, frailty+MetS group, and normal group, and the body compositions indicators of these groups were compared. Clavien-Dindo classification was used to grade the severity of postoperative complications. Univariate and multivariate regression models were performed to explore the independent and joint association of MetS and frailty with postoperative complications.

RESULTS

The incidence rate of MetS, frailty, and frailty+MetS being 20.3%, 15.7%, and 4.2% respectively. Compared with the normal group, both fat and muscle compositions were decreased significantly in the frailty group (p < 0.05), while the statistically significant difference of fat-to-muscle mass ratio (FMR) and skeletal muscle mass to visceral fat area ratio (SVR) were not observed (p > 0.05). In contrast, except SVR, the other indicators of the MetS group were higher than the normal group (p < 0.05). As to the frailty+MetS group, there was a significant increase in fat compositions and FMR, as well as a significant decline in SVR (p < 0.05), while the difference of muscle compositions was not statistically significant (p > 0.05). There was an association of frailty with postoperative total (OR = 3.068, 95% CI: 1.402-6.713) and severe (OR = 9.423, 95% CI: 2.725-32.589) complications, but no association was found of MetS alone. MetS coexisting with frailty was associated with the highest risk of both total (OR = 3.852, 95% CI: 1.020-14.539) and severe (OR = 12.096, 95% CI: 2.183-67.024) complications.

CONCLUSIONS

Both frailty and MetS coexisting with frailty had adverse effects on postoperative complications, which appeared greatly different characteristics in body compositions and therefore reinforced the importance of targeted nutritional or metabolic intervention. Although MetS alone were not significantly associated with postoperative complications, it is essential to focus on the causal relationship and development trend between MetS and frailty to prevent MetS from shifting into frailty, considering the highest risk in their coexistence state.

Influence of frailty status on the health-related quality of life in older patients with chronic low back pain: a retrospective observational study

PURPOSE

Understanding the influence of frailty on health-related quality of life (HRQoL) in older individuals experiencing chronic low back pain can provide valuable insights into the impact of frailty. Therefore, the aim of our study is to assess how different frailty statuses among older outpatients with chronic low back pain affect their HRQoL.

METHODS

Patients aged 60 and above with chronic low back pain were recruited from March 2022 to February 2023. Frailty was assessed via the frailty phenotype questionnaire, and HRQoL was evaluated using the EQ-5D-5L. Multiple regression models were used to explore the influence of frailty status on the EQ-5D-5L index and EQ-VAS. Logistic regression was used to determine odds ratios for the impact of frailty status on belonging to the lowest EQ-5D-5L index quartile.

RESULTS

A total of 1,054 participants were classified into robust (29.8%), pre-frail (47.7%), and frail (22.5%) groups. Frailty was significantly associated with declining HRQoL. Pre-frail and frail statuses were inversely linked to the EQ-5D-5L index, with significantly higher odds of scoring in the lowest quartile compared to robust individuals. Stratification analysis identified sex as an effect modifier, emphasizing a more substantial association between frailty and the lowest EQ-5D-5L index quartile in female patients.

CONCLUSIONS

A significant association exists between frailty and reduced HRQoL in patients with chronic low back pain. This association was predominant in female patients. Furthermore, considering the dynamic nature of frailty, early detection and effective interventions targeting pre-frailty are essential to delaying the transition to full frailty and improving HRQoL.

Nutritional Status and Sarcopenia in Nursing Home Residents: A Cross-Sectional Study

OBJECTIVE

This study aimed to assess the nutritional status and sarcopenia in older people living in nursing homes.

METHODS

This cross-sectional study enrolled 386 older adults in nursing homes in Hunan Province, China. Assessments included the Mini Nutritional Assessment Short Form for nutrition risk, Dietary Diversity Score for dietary diversity and Mini Mental State Examination for cognitive status. Sociodemographic (e.g., age, sex and educational level), health-related characteristics (e.g., food intake, self-care status and medication), body composition (e.g., body mass index [BMI], protein, body fat mass [BFM], percent body fat [PBF], skeletal muscle index [SMI] and total body water [TBW]) and anthropometric parameters data (e.g., calf circumference [CC], upper arm circumference [UAC], handgrip and gait speed) were also collected. Malnutrition and their associated risk were analyzed by multivariable Poisson regression analysis.

RESULTS

In total, 32.4% of participants (n = 125) were at risk of malnutrition and 49.7% (n = 192) suffered from sarcopenia. Nutritional status was positively associated with age (risk ratio [RR] = 1.03), sarcopenia (RR = 1.88), tooth loss affecting food intake (RR = 1.45), low self-care status (RR = 1.82) and moderate/inadequate dietary diversity (RR = 2.04) and negatively associated with one child (RR = 0.27), BMI (RR = 0.82), protein (RR = 0.76), BFM (RR = 0.91), PBF (RR = 0.94), SMI (RR = 0.65), TBW (RR = 0.94), CC (RR = 0.89) and UAC (RR = 0.86).

CONCLUSIONS

Age, number of children, sarcopenia, food intake, self-care status, dietary diversity and body composition were associated with malnutrition among nursing home residents. For vulnerable groups, researchers should focus on raising the body composition indicators, such as BMI, protein, BFM, SMI and TBW and measuring CC and UAC for initial screening.

Emerging Nutrition Approaches to Support the Mind and Muscle for Healthy Aging

This narrative review highlights recent advances and ongoing trials using nutrition approaches for healthy aging. Focus will be placed on nutrition therapies that target cognition ("the mind") and mobility ("the muscle"), both critical components to maintaining a high quality of life for older adults. For "the mind," two seemingly incongruent therapies are being investigated to improve cognition-the MIND diet (high in carbohydrates and anti-oxidant fruits and vegetables) and the ketogenic diet (low in carbohydrates, high in fats). For "the muscle," a focus on protein and energy intake has dominated the literature, yet a recent clinical trial supports the use of whole-grains as a tool to improve whole-body protein turnover-a primary regulator of lean body mass and muscle. Finally, emerging data and clinical trials on caloric restriction have solidified this strategy as the only nutritional approach to slow intrinsic factors of whole-body aging, which may positively impact both "the mind" and "the muscle."

Screening for frailty and sarcopenia in community-dwelling older adults: a cross-sectional study from the Eastern Black Sea region of Turkey

AIM

The purpose of this study was to investigate the prevalence of frailty, sarcopenia and associated factors among community-dwelling older adults living in the Eastern Black Sea region of Turkey.

METHODS

The study sample comprised 404 community-dwelling older adults living in the Eastern Black Sea region of Turkey. These subjects or proxies were contacted by mobile phone or the internet. The sociodemographic characteristics, falls and chronic pain were recorded. Frailty, sarcopenia, malnutrition, activities of daily living and instrumental activities of daily living were assessed using the FRAIL scale, SARC-F, Mini Nutrition Assessment-Short Form, Barthel Index and Lawton instrumental activities of daily living scale, respectively.

RESULTS

The 404 older adults comprised 62% females and 38% males with a mean age of 73.4 ± 7.4 years. The prevalence of positive frailty and sarcopenia screening were detected as 37.4% and 46.8%, respectively. The strongest associations with frailty were the presence of chronic lung disease [Odds ratio (OR) = 10.3; 95% confidence interval (CI) = 2.1, 49.8] and chronic pain [OR = 6.9; 95% CI = 3.2, 15.0]. The associations with sarcopenia were falls (OR = 7.4; 95% CI = 4.2, 12.9), dependence in instrumental activities of daily living (OR = 4.3; 95% CI = 2.2, 8.4), advancing age (OR = 2.6; 95% Cl = 1.4, 4.7), and dependence in daily living activities (OR = 2.2; 95% Cl = 1.3, 4.0). Female gender and falls were found to be co-related factors for frailty and sarcopenia.

CONCLUSIONS

Female gender and falls were independently associated with frailty and sarcopenia. In addition, chronic lung disease and chronic pain were major risk factors for frailty, while advancing age and dependence in daily living activities were major risk factors for sarcopenia. These factors should be considered to be able to identify individuals at high risk of frailty and sarcopenia and to prevent these geriatric syndromes.
