RESUMO
OBJECTIVE: Falls and fear of falling (FoF) are relevant contributors to disability and institutionalization among older adults. The aim was to examine the association between multimorbidity and falls/FoF among community-dwelling older adults, exploring the mediating effect of physical function and the use of sleeping pills and pain relievers. DESING: Longitudinal analyses. SETTING AND PARTICIPANTS: A total of 1824 adults aged ≥65 years from the Seniors-ENRICA II cohort (Spain). METHODS: Multimorbidity was defined as having ≥2 diseases from a predefined list of 13 chronic conditions extracted from clinical records. Falls were self-reported and FoF was estimated using the Short Falls Efficacy Scale International. Adjusted odds ratios (ORs) and 95% confidence intervals (CIs) were estimated for the association between multimorbidity/duration of multimorbidity and incident falls/FoF using logistic regression models. The mediating effects of physical function, the use of sleeping pills, and pain relievers were explored using the Karlson Holm Breen method. RESULTS: Multimorbidity was associated with a higher risk of falls (OR, 1.44; 95% CI, 1.14-1.82) and FoF (OR, 1.88; 95% CI, 1.48-2.39). Positive dose-response associations were found between the duration of multimorbidity and the risk of falls (P-trend = .003) and FoF (P-trend = .001). Physical function mediated 5.67% and 5.25% of these associations, respectively, and the use of sleeping pills explained a larger proportion of the associations (9.27% and 11.61%). Last, the mediation effect of pain relievers on the association between multimorbidity and falls was 3.05% and 9.31% in the multimorbidity-FoF association. CONCLUSIONS AND IMPLICATIONS: Multimorbidity was associated with a higher risk of falls/FoF among Spanish community-dwelling older adults. Use of sleeping pills was a relevant mediator, suggesting that interventions on sleep problems have the potential to reduce the burden of falls/FoF and their consequences among older adults with multimorbidity.
RESUMO
Tricyclic antidepressants are effective for managing depression and other disorders. However, they can cause adverse reactions due to their anticholinergic properties, with the risk of such events increasing with age. This study identifies and describes clinical studies that evaluate associations between the use of tricyclic antidepressants and adverse health outcomes (falls, fractures, and mortality) among older people. A systematic search of the literature in English, Spanish, and French was conducted using the electronic databases PubMed, ISI Web of Science, PsycINFO, and Cochrane. The systematic review included a total of 18 studies. The meta-analysis examined the 14 studies that investigated the association between the use of tricyclic antidepressants and the risk of falls and fractures (4 of the 18 studies focused on mortality and so were excluded from the meta-analysis). The odds ratio (OR) was 1.40 (95 % CI = 1.27-1.53, p < 0.001). The Cochran Q test was significant (X2 = 79.72, p < 0.001), indicating high heterogeneity (I2 = 84.9 %). An additional meta-analysis was conducted on studies reporting hazard ratios (HRs), yielding an HR of 1.21 (95 % CI = 0.93-1.58, p = 0.16). Meta-regression analysis indicated that the years of follow-up could have a significant effect on the association studied (p = 0.008). In conclusion, enhancing our understanding of the use of antidepressants and the associated risk of adverse events in older adults will enable the identification of the most appropriate type of antidepressant for each clinical situation.
RESUMO
CONTEXT: The melanocortin-4 receptor gene (MC4R) is associated with a higher risk of obesity by the presence of the C allele in rs17782313, but the mechanisms are not clear. OBJECTIVE: The present systematic review and meta-analysis aimed to explore the association between the different genotypes of MC4R rs17782313 and energy intake and appetite. DATA SOURCES: A literature search was conducted up to June 2023 in PubMed, Scopus, Web of Science, and Cochrane Collaboration databases, following PRISMA guidelines. DATA EXTRACTION: Inclusion criteria were studies in humans measuring energy intake, appetite, or satiety in all ages and physiological conditions. Studies dealing solely with body mass index were excluded. Twenty-one articles representing 48â560 participants were included in the meta-analysis. DATA ANALYSIS: According to the NHLBI (National Heart, Lung, and Blood Institute) quality-assessment criteria, all case-control studies and 6 out of 17 cohort and cross-sectional studies were classified as "good," while the rest scored as "fair." Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated in a (CT+CC) vs TT dominant model, and both random-effects and fixed-effects models were used. A statistically significant association between the presence of the C allele and increased appetite was found (OR = 1.25; 95% CI: 1.01-1.49; P = .038) using the fixed-effects model, but the random-effects model proved nonsignificant. However, no association with energy intake was found. None of the variables considered (sample size, year of publication, sex, age group, type of population, origin, and quality) were identified as effect modifiers, and no publication biases were found after subgroup and meta-regression analyses. CONCLUSION: To our knowledge, this is the first systematic review and meta-analysis that has analyzed the association between rs17782313 of MC4R and energy intake and appetite. Identifying people genetically predisposed to increased appetite may be of great interest, not only to prevent obesity in younger populations but also to avoid malnutrition in elderly persons.

RESUMO
BACKGROUND: Plant-based diets have gained attention due to their beneficial effects against major chronic diseases, although their association with multimorbidity is mostly unknown. OBJECTIVES: We examined the association between the healthful (hPDI) and unhealthful plant-based diet indices (uPDI) with multimorbidity among middle-aged and older adults from the United States. METHODS: Data on 4262 adults aged >50 y was obtained from the 2012-2020 Health and Retirement Study (HRS) and 2013 Health Care and Nutrition Study (HCNS). Food consumption was collected at baseline with a food frequency questionnaire and 2 PDIs were derived: the hPDI, with positive scores for healthy plant foods and reverse scores for less healthy plant foods and animal foods; and the uPDI, with only positive scoring for less healthy plant foods. Complex multimorbidity, defined as ≥3 coexistent conditions, was ascertained from 8 self-reported conditions: hypertension, diabetes, cancer, chronic lung disease, heart disease, stroke, arthritis, and depression. Cox proportional hazards models were used to estimate the hazard ratios (HRs) and 95% confidence intervals (CIs). RESULTS: After a median follow-up of 7.8 y, we documented 1202 incident cases of multimorbidity. Compared with the lowest quartile, higher adherence to the hPDI was inversely associated with multimorbidity (HR for quartile 3: 0.77; 95% CI: 0.62, 0.96 and HR for quartile 4: 0.79; 95% CI, 0.63, 0.98; P-trend = 0.02). In addition, a 10-point increment in the hPDI was associated with a 11% lower incidence of multimorbidity (95% CI: 1, 20%). No significant associations were found for the uPDI after adjusting for sociodemographic and lifestyle factors. CONCLUSIONS: Higher adherence to the hPDI was inversely associated with multimorbidity among middle-aged and older adults. Plant-based diets that emphasize consumption of high-quality plant foods may help prevent the development of complex multimorbidity.

OBJECTIVE: To examine the association between hearing function, assessed with pure-tone average (PTA) of air conduction thresholds, and 24-hour ambulatory blood pressure (BP) in older adults. STUDY DESIGN: Cross-sectional study. SETTING: A total of 1404 community-dwelling individuals aged ≥65 years from the Seniors-ENRICA cohort were examined. METHODS: Hearing loss was defined as PTA > 40-AudCal hearing loss decibels (dB-aHL) in the better ear for standard frequency (0.5, 1, and 2 kHz), speech frequency (0.5, 1, 2, and 4 kHz), and high frequency (3, 4, and 8 kHz). Circadian BP patterns were calculated as the percentage decline in systolic BP during the night, and participants were classified as dipper, nondipper, and riser. Ambulatory hypertension was defined as BP ≥ 130/80 mm Hg (24 hour), ≥135/85 (daytime), and ≥120/70 (nighttime) or on antihypertensive treatment. Analyses were performed with linear- and logistic-regression models adjusted for the main confounders. RESULTS: In multivariable analyses, the PTA was associated with higher nighttime systolic BP [ß coefficient per 20 dB-aHL increment standard frequency (95% confidence interval, CI): 2.41 mm Hg (0.87, 3.95); ß (95% CI) per 20 dB-aHL increment speech frequency 2.17 mm Hg (0.70, 3.64)]. Among hypertensive patients, hearing loss at standard and high-frequency PTA was associated with the riser BP pattern [odds ratio: 2.01 (95% CI, 1.03-3.93) and 1.45 (1.00-2.09), respectively]; also, hearing loss at standard PTA was linked to uncontrolled nighttime BP [1.81 (1.01-3.24)]. CONCLUSION: PTA was associated with higher nighttime BP, and hearing loss with a riser BP pattern and uncontrolled BP in older hypertensives.

OBJECTIVES: Malnutrition is a global concern in older adults, as it negatively affects morbidity and mortality. While higher animal protein intake may help prevent and treat malnutrition, it might also increase the risk of chronic diseases and death. Conversely, vegetable protein intake might have a lower anabolic effect and not be as effective to improve nutritional status. We studied whether animal and vegetable protein intake are associated with changes in nutritional status in older adults. DESIGN: We used pooled data from two Spanish cohorts: the Seniors-ENRICA 1 and Seniors-ENRICA 2. SETTINGS AND PARTICIPANTS: 2,965 community-dwelling adults aged 62-92 years. MEASUREMENTS: Protein intake was estimated at baseline via an electronic, validated diet history. Nutritional status was assessed at baseline and after 2.6 years with the GLIM (Global Leadership Initiative on Malnutrition) phenotypic criteria: weight loss, low body mass index, and reduced muscle mass. The odds of improvements in nutritional status were assessed with logistic regression models, extensively adjusted for potential confounders. RESULTS: Higher animal and vegetable protein intake were associated with improvements in nutritional status [odds ratios (95% confidence intervals) per 0.25 g/kg/day were 1.15 (1.00, 1.32) and 1.77 (1.35, 2.32), respectively]. Cereal protein intake drove most of the latter association [2.07 (1.44, 2.98)]. Replacing 0.25 g/kg/day of total animal protein, meat, or fish protein (but not dairy or egg protein) with vegetable protein was associated with improvements in nutritional status [1.54 (1.13, 2.09), 1.70 (1.20, 2.41), and 1.77 (1.18, 2.64), respectively]. CONCLUSIONS: Higher animal and, especially, vegetable protein intake were associated with improvements in nutritional status in older adults. Replacing total animal protein, meat, or fish protein with vegetable protein may help improve malnutrition.

The use of antidepressants with anticholinergic effects has been associated with an increased risk of dementia. However, the results published are contradictory. The aim of the study is to compare the risk of developing dementia in elderly who were prescribed tricyclic antidepressants (TCA) versus those who were prescribed selective serotonin reuptake inhibitors (SSRIs) and other antidepressants (OA). A prospective population-based cohort study was performed using the Spanish Database for Pharmacoepidemiological Research in Primary Care (BIFAP) data (from 2005 to 2018). The cohort study included 62,928 patients age ≥ 60 without dementia and with antidepressant long-term monotherapy. Patients were divided into exposure antidepressant groups based on ATC system [TCA, SSRIs users and OAs users]. The risk of dementia was calculated by Cox regression models, providing hazard ratios (HR) and 95 % confidence intervals. The Kaplan-Meier model was used for survival analysis. Chi2 test was used as association test. The results showed SSRI users had higher dementia risk than TCA users (HR = 1.864; 95%CI = 1.624-2.140). Moreover, OA users had also significant risk of dementia (HR = 2.103; 95%CI = 1.818-2.431). Several limitations are the variation of the trend in the prescription of antidepressants, the small number of patients that use some antidepressants, the lack of information related to the dose, or socioeconomic characteristics, the use of antidepressant drugs for other indications, or the therapeutic compliance. Our findings showed that older users of SSRI and OA have more risk of developing dementia than TCA elderly users. However, additional studies would be needed.

BACKGROUND: The role of diet quality in the accumulation of multiple chronic conditions is mostly unknown. This study examined diet quality in association with the number of chronic conditions and the rate of multimorbidity development among community-dwelling older adults. METHODS: We used data from 2 784 adults aged ≥65 years from the Seniors-ENRICA 2 cohort. Diet quality was assessed at baseline (2015-17) with the Alternate Healthy Eating Index-2010 (AHEI-2010) and the Mediterranean Diet Adherence Screener (MEDAS). Information on medical diagnoses was obtained from electronic clinical records up to 2021. RESULTS: Higher adherence to the AHEI-2010 was associated with a lower number of total chronic conditions (ß [95% CI] quartile 4 vs 1: -0.57 [-0.86 to 0.27], p trendâ <â .001] and cardiometabolic conditions (-0.30 [-0.44 to -0.17], p trendâ <â .001) at baseline, while higher adherence to the MEDAS was associated with a lower number of total chronic conditions (-0.30 [-0.58 to -0.02], p trendâ =â .01) and neuropsychiatric and neurodegenerative conditions (-0.09 [-0.17 to -0.01], p trendâ =â .01). After a median follow-up of 5.2 years (range: 0.1-6.1 years) higher adherence to the AHEI-2010 was associated with a lower increase in chronic conditions (ß [95% confidence interval] quartile 4 vs 1: -0.16 [-0.30 to -0.01], p trendâ =â .04) and with lower rate of chronic disease accumulation. CONCLUSIONS: Higher diet quality, as measured by the AHEI-2010, was associated with a lower number of chronic health conditions and a lower rate of multimorbidity development over time.

OBJECTIVE: To examine the care given to patients with hypertension in the Brazilian public and private health services in the population of Belo Horizonte, Minas Gerais. METHODS: Telephone interviews were conducted in a sample of hypertensive adults in the year 2009, in Belo Horizonte (n = 100). We compared the care provided to hypertensive users of the Unified Health System (SUS) and of the Supplementary Health (SS), using the χ2 test or Fisher's exact test. The prevalence ratio was calculated by the Poisson regression model, adjusted for the variables age, education and skin color. RESULTS: In the descriptive analysis, hypertensive users of private health plans had a higher frequency of physician referral and greater blood pressure control. Unified Health System users were the ones who participated in health promotion groups the most. The acquisition of antihypertensive medications by beneficiaries of private health insurance was more frequent in private pharmacies, and in Health Centers among users of the Unified Health System. The differences disappeared when adjusting the variables for age, race and education. There was no difference regarding the guidance received for a change of habits, or regarding the incorporation of these healthy practices promotion by hypertensive patients. CONCLUSION: A healthier diet, the practice of physical activity, and the non-use of alcohol and tobacco have been incorporated by hypertensive patients, whether owning private health insurance or not. Promotion practices, proper use of medication a clinical follow-up are important for the control of blood pressure levels. .
OBJETIVO: Analisar o cuidado dispensado aos hipertensos na população de Belo Horizonte, segundo posse ou não de plano de saúde privado. MÉTODOS: Foram realizadas entrevistas telefônicas em amostra de adultos hipertensos no ano de 2009 em Belo Horizonte (n = 100). O cuidado prestado aos hipertensos usuários do Sistema Único de Saúde (SUS) e Saúde Suplementar (SS) foram comparados usando os testes de χ2 de Pearson ou exato de Fisher. Foi calculada a razão de prevalência (RP), estimada pelo modelo de regressão de Poisson, ajustada segundo idade, escolaridade e cor da pele. RESULTADOS: Na análise descritiva, os hipertensos usuários de planos de saúde privado tiveram maior frequência de médico de referência e maior controle de pressão arterial. Os usuários do SUS foram os que mais frequentaram grupos operativos de promoção à saúde. A aquisição de medicamentos anti-hipertensivos pelos beneficiários da SS foi mais frequente nas farmácias privadas, e, entre os usuários do SUS, nos Centros de Saúde. As diferenças desapareceram ao se ajustarem as variáveis por idade, cor da pele e escolaridade. Não houve diferença quanto às orientações recebidas de mudanças de hábitos, e nem em relação à incorporação destas práticas saudáveis de promoção pelos hipertensos. CONCLUSÃO: Práticas de alimentação saudável, atividade física e o não uso de álcool e tabaco têm sido incorporados pelos hipertensos, independentes da posse ou não de planos de saúde. As práticas de promoção, uso correto de medicação e acompanhamento clínico são importantes para o controle dos níveis pressóricos. .
