The association between medication or alcohol use and the incidence of frailty: a retrospective cohort study

Association of HDL and LDL levels with osteoporosis in rheumatoid arthritis: a retrospective cohort study

OBJECTIVES

A correlation exists between lipids and osteoporosis (OP), as well as between lipids and rheumatoid arthritis (RA). However, lipids, the relationship between RA and OP is still unclear. This study mainly investigates the relationship between lipid levels and OP risk in RA patients.

METHODS

Retrospective collection of RA patient data from July 2017 to May 2022, encompassing baseline demographics, treatment regimens, laboratory results, and bone mineral density (BMD) measurements. Analyses, stratified by BMD subgroups, were conducted using propensity score matching (PSM) based on age, sex, and baseline duration, and binary logistic regression to examine the interplay between lipoprotein levels and other risk factors. The relationship between continuous variables and OP risk was assessed using restricted cubic spline (RCS), followed by a reanalysis of the correlation between varying lipoprotein levels and different factors, segmented according to RCS-determined cutoffs.

RESULTS

The study included 2673 RA patients. Binary logistic regression revealed significant associations between high-density lipoprotein (HDL), low-density lipoprotein (LDL), and RA-OP (p < 0.01). Specifically, HDL emerged as a protective factor against OP (OR = 0.40, 95% CI 0.250-0.629; p < 0.001), whereas LDL was identified as a risk factor (OR = 1.56, 95% CI 1.290-1.890; p < 0.001). Furthermore, HDL (RCS cutoff point 1.28 mmol/L) showed a negative, linear correlation with RA-related OP, while LDL (RCS cutoff point 2.63 mmol/L) demonstrated a positive, linear correlation.

CONCLUSIONS

The levels of HDL and LDL may be indicators of OP occurrence in RA patients.

Association between adherence to the Nordic diet and frailty in older adults: A systematic review of observational studies

BACKGROUND

The Nordic or Baltic Sea diet is a healthy plant-based dietary pattern composed of foods originating from Nordic countries, closely related to the Mediterranean diet. Adherence to the Mediterranean diet has been found to be associated with a reduced risk of frailty. Although adherence to the Nordic diet has been associated with health benefits, little is known about its association with frailty.

OBJECTIVES

To investigate the evidence from observational studies regarding the association between the Nordic/Baltic Sea diet and frailty among older adults.

DESIGN

Systematic review.

METHODS

Three databases (Medline/Ovid, Embase/Ovid, and Scopus) were systematically searched in February 2023 for observational studies examining the association between adherence to the Nordic diet and frailty among adults ≥60 years. The two authors independently assessed the full text of the papers for eligibility of studies and risk of bias.

RESULTS

Three studies (the results of which were reported across 6 papers) met the inclusion criteria, among which one study (2 papers) included only women. Greater adherence to the Nordic diet was associated with a reduced risk of frailty measured by modified Fried criteria in women (one study). Moreover, greater adherence to the Nordic diet was associated with improved muscle (handgrip/leg) strength (one study) and physical performance (two studies), but these differences were seen only in women, with no significant results in men in two studies. Greater adherence to the Nordic diet was also associated with a lower risk of mobility limitations and improved ability to carry out self-care tasks (one study) and a borderline non-significant difference in Activities of Daily Living (one study). A meta-analysis was not performed due to heterogenous outcomes. Although all studies were of good quality, the results should be carefully interpreted due to methodological limitations.

CONCLUSIONS

Adherence to the Nordic diet could be promising in reducing frailty risk, but more robust studies with equal gender representation and frailty-specific outcomes are needed.

Evaluating the Sick Quitting Hypothesis for Frailty Status and Reducing Alcohol Use Among People With HIV in a Longitudinal Clinical Cohort Study

ABSTRACT

"Sick quitting," a phenomenon describing reductions in alcohol consumption following poor health, may explain observations that alcohol appears protective for frailty risk. We examined associations between frailty and reductions in drinking frequency among people with HIV (PWH). At six Centers for AIDS Research Network of Integrated Clinical Systems (CNICS) sites between January 2012 and August 2021, we assessed whether frailty, measured through validated modified frailty phenotype, precedes reductions in drinking frequency. We associated time-updated frailty with quitting and reducing frequency of any drinking and heavy episodic drinking (HED), adjusted for demographic and clinical characteristics in Cox models. Among 5,654 PWH reporting drinking, 60% reported >monthly drinking and 18% reported ≥monthly HED. Over an average of 5.4 years, frail PWH had greater probabilities of quitting (HR: 1.56, 95% confidence interval [95% CI] [1.13-2.15]) and reducing (HR: 1.35, 95% CI [1.13-1.62]) drinking frequency, as well as reducing HED frequency (HR: 1.58, 95% CI [1.20-2.09]) versus robust PWH. Sick quitting likely confounds the association between alcohol use and frailty risk, requiring investigation for control.

Association between alcohol use and frailty among elder adults in three Chinese cities

BACKGROUND

Frailty is often described as a condition of the elderly and alcohol use is associated with frailty. The aim of this study is to examine the associations between alcohol use and frailty in three cities in elder adults.

METHODS

A cross-sectional study was conducted in three cities in China from June 2017 to October 2018. In total, 2888 residents aged ≥65 years old were selected by using a multi-level stage sampling procedure. Alcohol use was assessed by Focusing on Cutting down, Annoyance by criticism, Guilty feeling, and Eye-openers (CAGE) four-item questionnaire. Frailty was measured by a validated Chinese version of the Fatigue, Resistance, Ambulation, Illness, and Loss of weight (FRAIL) scale. Multinomial logistic regressions were used to examine the association of alcohol use with pre-frailty and frailty after controlling for varied covariates.

RESULTS

In general, the prevalence of pre-frailty and frailty was 38.64 and 20.26%, respectively. After controlling for covariates and interaction of age and problematic drinking, non-problematic drinkers neither had association with pre-frailty (OR: 1.15, 95%CI:0.86-1.52) nor with frailty (OR:0.90, 95%CI:0.60-1.36), and problematic drinkers neither had association with frailty (OR: 1.21, 95%CI:0.83-1.76), while problematic drinkers had high odd ratios of frailty (OR:3.28, 95%CI:2.02-5.33) compared with zero-drinker.

CONCLUSIONS

Our study found a positive association between problematic drinking and frailty, no relationship between non-problematic drinking and (pre-)frailty compared with zero-drinking among Chinese elder adults. Based on previous findings and ours, we conclude it is important for the prevention of frailty to advocate no problematic drinking among elder adults.

Tobacco and alcohol consumption and the risk of frailty and falling: a Mendelian randomisation study

Background

Epidemiological data have suggested that tobacco and alcohol consumption were associated with the risk of frailty and falling, but it is yet unclear whether these associations are of a causal nature. Thus, we conducted two-sample Mendelian randomisation analysis using genetic instruments to determine the causal associations of tobacco and alcohol consumption on frailty and falls.

Methods

Independent instrumental variables strongly (p<5E–09) associated with tobacco and alcohol consumption were obtained from the genome-wide association study (GWAS) and Sequencing Consortium of Alcohol and Nicotine use (up to 2 669 029 participants). Summary statistics of the frailty index (FI, N=175 226) and falling risk (N=451 179) were from the two latest published GWAS datasets on FI and falling risk.

Results

Using the inverse-variance weighted method, our results showed that genetically determined initiation of smoking was significantly associated with an increased FI (β=0.34, 95% CI=0.29 to 0.40, p=5.48E–33) and risk of falling (OR=1.39, 95% CI=1.30 to 1.50, p=1.01E–20). In addition, the age of initiation of smoking and cigarettes consumption per day was negatively and positively associated with both FI and falls, respectively. Current smokers were prone to having a higher FI and falling risk than individuals who quit smoking. There was no significant causal association between alcohol use and the risk of frailty and falling. Similar results were obtained using other statistical approaches with good stability.

Conclusions

Our findings demonstrate that tobacco use, but not alcohol drinking, significantly increases the risk of frailty and falling. Future studies are warranted to clarify the underlying physiopathological mechanisms.

Progression of frailty as measured by a cumulative deficit index: A systematic review

BACKGROUND

Frailty is a risk factor for adverse health outcomes. There is a paucity of literature on frailty progression defined by a cumulative deficit model among community dwelling older people. The objective of this review was to synthesise evidence on these changes in health and mortality among community-dwelling older people.

METHODS

Six databases (Medline, Embase, CINAHL, Cochrane, PsycInfo, Web of Science) and a clinical trials registry were searched in July 2021. The inclusion criteria were studies using a frailty index and providing information on transition between frailty states or to death in community-dwelling older people aged ≥ 50. Exclusion criteria were studies examining specific health conditions, conference abstracts and non-English studies. To standardise the follow-up period and facilitate comparison, we converted the transition probabilities to annual transition rates.

RESULTS

Two reviewers independently screened 5078 studies and 61 studies were included for analysis. Of these, only three used the same frailty state cut-points to facilitate cross-cohort comparison. This review found that frailty tends to increase with time, people who are frail at baseline have greater likelihood to progress in frailty and die, and the main factor that accelerates frailty progression is age. Other risk factors for progression are having chronic disease, smoking, obesity, low-income or/and low-education levels. A frailty index is an accurate predictor of adverse outcomes and death.

DISCUSSION

This systematic review demonstrated that worsening in frailty was a common frailty transition, and older people who are frail at baseline are more likely to die. A frailty index has significant power to predict adverse health outcomes. It is a useful tool for within-cohort comparison but there are challenges comparing different cohorts due to dependence of frailty progression on age and differences in how frailty index is defined and measured.

Activity diversity is associated with the prevention of frailty in community-dwelling older adults: The Otassha Study

Introduction

A prior study showed an association between diversity in daily activities (type, frequency, evenness) and frailty in older adults. However, the causality of this relationship is unclear. Therefore, this study aimed to clarify the relationship between activity diversity and frailty through a 2-year longitudinal study conducted among community-dwelling older adults.

Methods

We evaluated data from the 2018 and 2020 waves of the Otassha Study. Frailty was assessed using the Cardiovascular Health Study criteria, with pre-frail and frail participants defined as frail and the other participants categorized into the robust group. We enrolled a total of 207 participants who were not frail at baseline. Activity type, frequency, and evenness scores were calculated using an Activity Diversity Questionnaire. The association between each activity diversity score and the incidence of frailty was evaluated using logistic regression modeling (each diversity score was entered the model after Z-transformation).

Results

Of the 207 enrolled participants (median age, 73 years; age range, 65-91 years; 60.4% women), 64 (30.9%) had incident frailty during the follow-up period. A logistic regression analysis adjusting for sociodemographic and psychosomatic factors revealed odds ratios for activity type and evenness scores of 0.64 and 0.61, respectively (P < 0.05). These factors were significantly associated with the incidence of frailty.

Discussion

Activity type and evenness (except frequency) within daily activities were predictors of frailty during 2 years of follow-up. Engagement in diverse activities appears to be more effective in preventing frailty than does engagement in a few activities.

Predictors of Maintained Transitions Between Robustness and Prefrailty in Community-Dwelling Older Spaniards

OBJECTIVES

We aimed to explore predictors of sustained transitions (those that are maintained for an extra follow-up) between robustness and prefrailty in both directions.

DESIGN

Longitudinal population-based cohort.

SETTING AND PARTICIPANTS

Community-dwelling Spaniards 65 years or older from the Toledo Study of Healthy Ageing.

METHODS

The Fried's frailty phenotype was measured over 3 waves (2006-2009, 2011-2013, and 2014-2017). Multiple logistic regressions compared individuals following the pattern robust-prefrail-prefrail with those who remained robust across waves, and those following the pattern prefrail-robust-robust with those who remained prefrail, for sociodemographic, clinical, life-habits, dependency for activities of daily living, upper and lower extremities' strength variables. The Fried's items of those who remained prefrail and those who became robust were compared.

RESULTS

Mean age was 72.3 years (95% CI: 71.8-72.8) and 57.9% (52.7%-63.0%) were women. After multivariate adjustment, predictors (apart from age) of the sustained transition robustness-prefrailty were as follows: number of drugs taken (odds ratio: 1.37; 95% CI: 1.14-1.65), not declaring the amount of alcohol consumed (8.32; 1.78-38.88), and grip strength (0.92 per kg; 0.86-0.99). Predictors of the sustained transition prefrailty-robustness were as follows: drinking alcohol (0.2; 0.05-0.83), uricemia (0.67; 0.49-0.93), number of chair stands in 30 seconds (1.14; 1.01-1.28), and grip strength (1.12; 1.05-1.2). Low grip strength was associated with a lower probability of regaining robustness.

CONCLUSIONS AND IMPLICATIONS

Prediction of sustained transitions between the first stages of frailty development can be achieved with a reduced number of variables and noting whether the Fried's item leading to a diagnosis of prefrailty is low grip strength. Our results suggest the need to intensify interventions on deprescription, quitting alcohol, and strengthening of upper and lower limbs.

Prevalence of frailty in patients with polymyalgia rheumatica and association with health-related quality of life, cognition and sarcopenia

OBJECTIVE

To describe the prevalence of frailty in a single-centre cohort of patients with PMR and describe its association with health-related quality of life (HRQoL), cognition and sarcopenia.

METHODS

This was a cross-sectional study of patients with PMR, according to 2012 EULAR/ACR Classification Criteria, presenting within 12 months of diagnosis and on treatment with glucocorticoids. Frailty was defined according to the Fried frailty criteria. HRQoL was assessed using Patient-Reported Outcomes Measurement Information System Computerized Adaptive Test (PROMIS-CAT) and cognition was assessed using the Mini-Mental State Examination. Sarcopenia was measured by DXA.

RESULTS

Forty-one patients were enrolled. Prevalence of frailty and pre-frailty was 17% and 59%, respectively. Frail patients had higher inflammatory markers at diagnosis compared with pre-frail and robust patients. Of 27 patients with DXA results, 26% were sarcopenic. Frail patients had worse physical function, and more pain behaviour and interference compared with pre-frail and robust patients. In univariable analyses, frail patients were more likely to have worse physical function, and more pain behaviour and pain interference, which remained significant after adjusting for age. There were no significant associations between cognition or sarcopenia and frailty.

CONCLUSIONS

In this cohort of PMR patients, there was a higher prevalence of frailty and pre-frailty compared with that reported in community-dwelling elderly. Frailty was associated with worse physical function, and increased pain behaviour and pain interference, differences that were also clinically meaningful. Larger prospective studies are needed to confirm these findings and analyse the association of frailty with other PMR disease outcomes.

The impact of household wastewater on the frailty state of the elderly in China: based on a long-term cohort study in China

China's household wastewater discharge has gradually increased, and its composition has become more complex, but the discharge treatment system is not perfect. At present, there is a lack of research on the impact of domestic wastewater on human health, especially on the frailty of the elderly. This study aimed to quantitatively assess the relationship between living wastewater and its main components and the frailty status of the elderly. The research data comes from the Chinese Longitudinal Healthy Longevity Survey (CLHLS), which consists of participants over 60 years old who participated in the three-wave survey in 2008, 2011, and 2014 and combined with domestic wastewater data in the statistical yearbook. A generalized estimating equation (GEE) model was used to assess the link between living wastewater and frailty status in the elderly. The single-pollutant model showed that there was a positive correlation between the discharge of household wastewater and the frailty of the elderly, OR (4.443), 95%CI (3.591, 5.498); ammonia nitrogen had a positive correlation with the frail state of the elderly, OR (4.527), 95%CI (3.587, 5.714); chemical oxygen demand (COD) had a negative association with whether the elderly are frail, OR (0.776), 95%CI (0.609, 0.988). After adjusting for covariates, there was still a positive correlation between household wastewater and the frailty of the elderly, OR (2.792), 95%CI (2.233, 3.492); a positive correlation between ammonia nitrogen and the frail state of the elderly, OR (2.894), 95%CI (2.284, 3.666). The association between COD and the frail state of the elderly, OR (0.823), 95%CI (0.640, 1.058), showed no correlation between the two. The results show that household wastewater may affect the health of the elderly, promote the occurrence of a frail state of the elderly, and increase the medical burden.

Oral Factors as Predictors of Frailty in Community-Dwelling Older People: A Prospective Cohort Study

The purpose of this prospective cohort study was to identify predictors for frailty among possible oral factors in community-dwelling older people. Ninety-seven participants (≥60 years old) without frailty at baseline were included and assigned to either the robust or the frailty group after 2-year follow-up. The frailty was defined using the Japan Cardiovascular Health Study index. The numbers of present and functional teeth and periodontal disease severity were recorded. Bacterial counts on the dorsum of the tongue, oral moisture, tongue pressure, occlusal force, masticatory ability, and the oral diadochokinesis (ODK) rate were measured. Swallowing function, along with psychosocial status, relationships with communities and people, nutritional status, medical history, and comorbidities were evaluated using a questionnaire. The newly identified frailty group at follow-up showed significantly lower values in the number of teeth present, ODK/ta/sound and ODK/ka/sound rates, and clinical attachment level at baseline compared to the robust group. A logistic regression model showed a significantly negative association between the ODK/ta/sound rate at baseline and the incidence of frailty. Articulatory oral motor skill was found to be a predictor of frailty after two years.
