ABSTRACT
OBJECTIVE: To verify the association between low self-reported sleep quality (LSQ) and fall in middle-aged and older adults every half-decade of life. METHOD: A cross-sectional study was conducted using data from the first wave (2015-2016) of the Brazilian Longitudinal Study of Aging (ELSI-Brazil), which is nationally representative. The sample consisted of 8,950 participants who were allocated into eight age groups: 50-54, 55-59, 60-64, 65-69, 70-74, 75-79, 80-84, and ≥ 85 years. The questionnaires used included self-reported sleep quality and the International Physical Activity Questionnaire short version. Fisher's exact test followed by binary logistic regression analysis was performed to identify the odds ratio of sleep quality for fall occurrence, controlled for confounding variables. RESULTS: Individuals aged 50-105 years (63.6 ± 10.2 years), 57.0% females and 43.0% males, participated in this study. Overall, 21.5% of participants experienced at least one fall. The relative frequency of participants classified as having high or LSQ remained constant across each half-decade of life. The LSQ exhibited a statistically significant OR (p < 0.05) for falls across age groups up to 84, even after accounting for confounding variables. CONCLUSION: LSQ is significantly associated with an increased occurrence of fall in adults aged >50 years, but not for ≥ 85 years regardless of sex and physical activity level.

The aim of the study was to determine the role of isometric strength and range of motion in predicting Functional Movement Screen (FMS) scores of adults. A total of 120 participants (age = 34.62 ± 11.82 years; height = 170.56 ± 9.63 cm; weight = 73.62 ± 15.39 kg) volunteered to participate in the study. Anthropometric measurements were performed, including height, body weight, muscle mass, and body fat. Following this, the ranges of motion of the shoulder, hip, knee, and ankle joints were measured sequentially. Isometric strength and FMS tests were then performed. Hip extension isometric strength explained 23% of the variation in FMStotal. The common effect of knee flexion, shoulder flexion, and dorsiflexion joint range of motion explained 34% of the change in FMStotal (F (3-116) = 20.375, p < 0.001). A significant relationship (R = 0.658, R2 = 0.413) was found between hip extension isometric strength, knee flexion, shoulder flexion, and dorsiflexion range of motion and FMStotal (F (4-115) = 21.952, p < 0.001). The common effect of all these variables explains 43% of the change in FMStotal. The results indicate that the FMS test scores, which are utilized to evaluate the risk of injury in sedentary adults, can be significantly predicted by the effect of hip extension isometric strength and parameters related to knee flexion, shoulder flexion, and dorsiflexion joint range of motion. At this time, it is advised that range of motion and isometric strength be taken into account when determining a person's functional movement capacity.
ABSTRACT
OBJECTIVE: This study aimed to ascertain the accuracy of measure arterial stiffness using the HUAWEI GT 3 Pro smartwatch and pOpmètre device against the SphygmoCor (algorithms: intersect tangent and maximum of the second derivate). METHODS: Twenty-three physically active postmenopausal women (age: 58.9 ± 3.2 years; body mass index: 26.3 ± 4.8 kg/m 2 ) were recruited. Carotid-femoral pulse wave velocity, finger-toe pulse wave velocity, and wrist-finger pulse wave velocity were obtained using SphygmoCor, pOpmètre and HUAWEI GT 3 Pro devices in a randomized order. Additionally, the pulse mean carotid-femoral and finger-toe pulse transit time was registered for SphygmoCor and pOpmètre, respectively. RESULTS: Lower values of pulse wave velocity were recorded by HUAWEI in comparison with SphygmoCor with both algorithms, whereas no significant differences were detected between SphygmoCor and pOpmètre results. Pulse wave velocity values from SphygmoCor were positively correlated with pOpmètre results ( r = 0.464 and r = 0.451 using intersect tangent and second derivative algorithms), whereas this was not the case with those obtained from HUAWEI. Coefficients of bias of Lin's concordance coefficients close to 1 (0.832 and 0.831 for intersect tangent and second derivative algorithm, respectively) and mean bias close to 0 from Bland-Altman analysis suggested an acceptable agreement between pulse wave velocity obtained from SphygmoCor and pOpmètre. CONCLUSIONS: Our results suggest an acceptable concordance of pulse wave velocity values recoded by SphygmoCor and pOpmètre, whereas this was not the case for data obtained from HUAWEI GT 3 Pro smartwatch. Therefore, the pOpmètre may be a viable alternative for assessing arterial stiffness, but measurement via the smartwatch device cannot be recommended.

Background: There is a limited research on predictive models of fat mass ratio (FMR) in people living with human immunodeficiency virus (HIV) (PWH). This study aimed to develop models considering anthropometric and health-related factors to predict and validate FMR in PWH regardless of sex. Methods: One hundred and six Brazilian PWH (46.4±9.8 years) were evaluated for body composition using dual-energy X-ray absorptiometry (DXA), body circumference (BC), and skinfold thicknesses (SKs). FMR predictive models were developed using stepwise linear regression, and their agreement with DXA was assessed using Bland-Altman plots. Cross-validation was performed using the predicted residual error sum of squares (PRESS) method. Results: Six FMR estimation models were developed for PWH, with adjusted R2 ranging from 0.43 to 0.72, standard error of the estimate (SEE) from 0.16% to 0.22%, and 95% confidence interval (CI) from 1.03 to 1.15. Model 6, including thigh SK, waist BC, therapy duration, subscapular SK, education years, and abdominal SK, exhibited the highest determination power (R2 adjusted 0.72, SEE 0.16%, and 95% CI: 1.06-1.15). The agreement between DXA-based FMR and predictive models showed minimal bias (-0.03 to +0.04) and narrower limits of agreement, particularly for the top-performing model (-0.33 to +0.30). Model 6 exhibited a high adjusted Q2PRESS (0.70) and low SPRESS (0.17). Conclusions: Our predictive models advance the study of body composition in PWH by consolidating the use of anthropometry for diagnosing and monitoring lipodystrophy regardless of sex.
ABSTRACT
This study examined the prevalence and the impact of fear of falling (FOF) on physical activity (PA), sedentary behavior (PA), and physical function in older adults living in a continuing care retirement community (CCRC). Ninety-three older adults were included and self-reported assessed on PA and SB. Further, participants' physical function was assessed using a collection of measures of valid objective tests. Independent t test was used to compare the dependent variables between FOF groups, and analysis of covariance (ANCOVA) was used to control for assistive device usage. FOF was prevalent in 47.3% of the sample and PA and SB did not differ between FOF groups (p > .05). ANCOVA revealed that performance on several physical function tests remained significantly better (p < .05) for the no FOF group compared to the yes group. Our findings demonstrated similar levels of PA and SB between FOF groups, but worse physical function for older adults reporting FOF.

ABSTRACT
BACKGROUND: Neuropsychiatric symptoms (NPS) are highly prevalent among individuals with major neurocognitive disorders (MNCD). OBJECTIVE: Here, we characterized blood biomarkers (metabolic, inflammatory, neurotrophic profiles and total antioxidant), body composition, physical fitness and quality of life (QoL) in individuals with MNCD according to NPS. METHODS: The sample comprised 34 older adults (71.4% women; 74.06±6.03 yrs, with MNCD diagnosis) categorized according to 50th percentile [Low (≤12) or High (≥13)] for NPS (Neuropsychiatric Inventory Questionnaire). Sociodemographic, clinical data, body composition, anthropometric, cognitive assessment (ADAS-Cog), physical fitness (Senior Fitness Test), QoL (QoL-Alzheimer's Disease scale) were evaluated, and blood samples were collected for biochemical analysis. RESULTS: Low compared to high NPS group showed higher levels of IL-6, IGF-1and neurotrophic zscore (composite of IGF-1, VEGF-1, BDNF). Additionally, low compared to high NPS group have higher QoL, aerobic fitness and upper body and lower body strength. CONCLUSION: The severity of NPS seems to be related to modified neurotrophic and inflammatory outcomes, lower physical fitness, and poor QoL. Strategies to counteract NPS development may preserve the physical and mental health of individuals with MNCD.
ABSTRACT
BACKGROUND: It is plausible that depression symptoms and disrupting sleep quality were differently affected according to the rigidity of social distancing during the COVID-19 outbreak. OBJECTIVE: To describe and compare depression symptoms and sleep quality amongst older Brazilian and Chinese women who were submitted to different social distancing measures (less rigid (Brazil) versus more rigid (China)). METHODS: This observational cross-sectional study assessed urban older women who underwent home confinement with less (Brazil; n=1015) or more (China; n=644) rigidity. Socio-demographic correlates, general health information, depression symptoms [Geriatric Depression Scale (GDS15)], and sleep quality [Pittsburgh Sleep Quality Index (PSQI)] were assessed through interviews. RESULTS: 1659 older women (66.74 ± 5.48 years old; 38.8% Chinese; 61.2% Brazilian) were included for analysis. 22% of Brazilians and 19.6% of Chinese women presented depression symptoms. The frequency of bad sleepers was 56.4% and 37.7% amongst Brazilian and Chinese older women, respectively. After adjusting for socio-demographic variables, general health status, and PSQI global score, Chinese women had a significantly higher score of depression symptoms (3.88 ± 0.13) compared to the Brazilians (3.26 ± 0.10; p < 0.001). CONCLUSION: The frequency of poor sleep quality was very high regardless of the country. After adjusting for confounders and sleep quality, older Chinese women had a significantly superior score. of depression symptoms exacerbating psychological distress by confinement rigidness.
ABSTRACT
BACKGROUND: The implementation of social distancing measures during covid-19 influenced health outcomes and population´s behaviors, and its rigidity was very different across countries. We aimed to verify the association between the rigidity of social distancing measures of covid-19 first wave with depression symptoms, quality of life and sleep quality in older adults. METHODS: This is a cross-sectional study including 1023 older adults (90% women; 67.68 ± 5.92 years old) of a community-based program in Fortaleza (Brazil). Dependent variables (depression symptoms, sleep quality, and quality of life) were measured through phone calls along June 2020, during the first covid-19 wave. Confinement rigidity (non-rigorous and rigorous) was considered as independent variable. Sociodemographic characteristics (sex, marital status, scholarity, and ethnicity), number of health conditions, nutritional status, movement behavior (physical activity and sitting time), technological skills, and pet ownership were considered as confounding variables. A binomial logistic regression (odds ratio [OR]) was performed to verify the association of confinement rigidity and depression symptoms, sleep quality, and quality of life, adjusted by confounding variables. RESULTS: Older adults who adopted a less rigid lockdown had a higher frequency of depression symptoms, worse perception of quality of life, and bad sleep quality (p < 0.001). Confinement rigidity was able to explain the probability of depression symptoms occurrence (OR: 2.067 [95% CI: 1.531-2.791]; p < 0.001), worse quality of life (OR: 1.488 [95% CI: 1.139-1.944]; p < 0.05), and bad sleep quality (OR: 1.839 [95% CI: 1.412-2.395]; p < 0.001). Even adjusted by confounding variables, confinement rigidity was able to explain the poor outcomes analyzed in older adults. CONCLUSION: Our findings showed that less rigid lockdown was associated with a superior frequency of depression symptoms, worse sleep quality, and lower perception of quality of life in older adults. Therefore, our study could improve comprehension regarding the impact of social distancing measures rigidity in health-related conditions and in the context of covid-19 and other similar pandemic situations.
ABSTRACT
Background: Sarcopenic obesity (SO) is a clinical and functional disease characterized by the coexistence of obesity and sarcopenia. Resistance training (RT) characteristics for older adults with sarcopenia or obesity are already well established in the scientific literature. Nonetheless, we still do not know how detailed the RT protocols are described for older adults with SO. Therefore, we aimed to analyze the characteristics of RT programs, including each of their variables, recommended for older adults with SO. Methods: This is a scoping review study that was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analysis for Scoping Reviews. The search was carried out until November 2022 in PubMed/MEDLINE, EMBASE, Cochrane Library, Web of Science, Scopus, LILACS, Google Scholar, and medRxiv databases. The studies included SO diagnosis and RT as an intervention strategy. The RT variables analyzed were as follows: exercise selection, the volume of sets, the intensity of load, repetition cadence, rest interval between sets, and weekly frequency. Results: A total of 1,693 studies were identified. After applying the exclusion criteria, 15 studies were included in the final analysis. The duration of the RT intervention ranged from 8 to 24 weeks. All studies included full-body routines, with single/multi-joint exercises. Regarding the volume of sets, some studies fixed it in three sets, whereas others varied between one and three sets. The load was reported by repetition range and the weight lifted, elastic-band color/resistance, percentage of one repetition maximum, or perceived exertion scale. Repetition cadence was fixed in some studies, while it was self-selected between concentric and eccentric phases in others. The interval between sets of rest varied from 30 to 180 s. All studies reported progression overload during the interventions. Not all studies reported how the exercise selection, repetition cadence, and rest interval were made. Conclusion: The characteristics of RT protocols and their variables prescribed in the literature for older adults with SO were mapped. The lack of detail on some training variables (i.e., exercise selection, repetition cadence, and rest interval) was identified. RT protocols are heterogeneous and described only partially among studies. The recommendations for RT prescription details in older adults with SO are provided for future studies.

ABSTRACT
BACKGROUND: In healthy older adults, the two-minute step test (2MST) does not have its concurrent validity tested against the six-minute walk test (6MWT), which is a valid cardiorespiratory fitness test frequently applied in geriatric samples. OBJECTIVE: To derive an equation to predict 6MWT from 2MST and to observe the agreement between observed and estimated 6MWT distances. METHODS: 6MWT and 2MST were measured in 51 older adults (72.9±4.6 years) from community multicomponent exercise programs. Multiple linear regression derives the predictive equation of 6MWT walked distance (dependent outcome) from steps obtained in 2MST, age, sex, and body mass index (independent outcomes). RESULTS: Correlation between 6MWT and 2MST was strong (r=0.696, p<0.001). The regression equation showed good agreement with measured values, when 6MWT was below 600 m. CONCLUSION: The equation stands as a novel approach to obtaining a valid 6MWT estimation from the 2MST. 2MST is easier and faster, representing an alternative approach when time and space are limited.

BACKGROUND: Handgrip strength (HGS) is a well-established clinical biomarker that assesses functional capacity in older populations. In addition, HGS is a diagnostic tool that forecasts aging health conditions, such as sarcopenia. AIMS: This paper provides HGS statistical tolerance regions and presents the need to establish HGS reference values according to patients' characteristics. METHODS: For this purpose, we used a conditional tolerance algorithm for HGS, and we observed the tolerances regions in different age strata and sex of non-sarcopenic individuals from the National Health and Nutrition Examination Survey (NHANES, wave 2011-2012). RESULTS AND DISCUSSION: Our results have critical implications for sarcopenia, since conventional and available HGS cut-offs do not consider age range. CONCLUSIONS: This paper offers new perspectives on the evolution of traditional definitions of sarcopenia according to the principles of precision medicine.

INTRODUCTION: The time spent in different physical activity (PA) intensities is associated with sarcopenia risk for community-dwelling older women. AIM: To evaluate the role of sitting time and physical activity (PA) level as predictors of sarcopenia odds. METHODS: In a cross-sectional study, physically independent older women (n = 67) performed the six-minute walk test to identify functional limitation (≤ 400 m). Sedentary time (as sitting time) and PA (light, moderate and vigorous) were obtained with the International Physical Activity Questionnaire (IPAQ). Sarcopenia was diagnosed as recommended by the Society of Sarcopenia, Cachexia and Wasting Disorders (SCWD). Sarcopenia odds (low muscle mass and functional limitation) was predicted by binary logistic regression, considering the weekly sitting time and PA as independent variables. RESULTS: Sarcopenia prevalence was 7.5% (n = 5), with functional limitation present in 38.8% (n = 26), and low muscle mass in 22.4% (n = 15). The predictive model (p = 0.014) involved moderate PA as the only significant predictor (OR = 0.999; p = 0.005; 95% CI: 0.998-1.000) of functional limitation. Moderate PA prevents sarcopenia odds. Each weekly hour of moderate PA decreased sarcopenia odds by 6%. CONCLUSION: Time spent in moderate PA can prevent sarcopenia.

BACKGROUND: Appendicular skeletal muscle mass (ASM) obtained from dual-energy x-ray absorptiometry (DXA) is recommended to quantify sarcopenia, but has limited availability in disadvantaged-income countries, moreover in an epidemiological context. Predictive equations are easier and less costly to apply, but a review of all available models is still lacking in the scientific literature. The objective of this work is to map, with a scoping review, the different proposed anthropometric equations to predict ASM measured by DXA. METHODS: Six databases were searched without restriction on publication date, idiom, and study type. A total of 2,958 studies were found, of which 39 were included. Eligibility criteria involved ASM measured by DXA, and equations proposed to predict ASM. RESULTS: predictive equations (n = 122) were gathered for 18 countries. The development phase involves sample size, coefficient of determination (r2), and a standard error of estimative (SEE) varying between 15 and 15,239 persons, 0.39 and 0.98, 0.07 and 3.38 kg, respectively. The validation phase involves a sample size, accuracy, and a SEE between 15 and 3,003 persons, 0.61 and 0.98, 0.09 and 3.65 kg, respectively. CONCLUSIONS: The different proposed predictive anthropometric equations of ASM DXA were mapped, including validated pre-existing equations, offering an easy-to-use referential article for clinical and research applications. It is necessary to propose more equations for other continents (Africa and Antarctica) and specific health-related conditions (e.g., diseases), once the equations can only have sufficient validity and accuracy to predict ASM generally when applied to the same population.

Introduction: Introduction: food type represents higher odds of having obesity (OB), especially in overweight (OW) subjects. Minimally and ultra-processed foods can be associated with the odds of having OB in OW subjects. Objective: to investigate the association of minimally and ultra-processed food consumption with OB in OW adults. Methods: we included 15,024 participants (9,618 OW [25.0-29.9 kg/m2], 5,406 OB [≥ 30 kg/m2]) with ages ranging from 18 to 59 years from the 2019 baseline survey of the Surveillance of Risk Factors and Protection for Chronic Diseases by Telephone Survey (VIGITEL, Brazil). Minimally and ultra-processed food daily consumption scores and confounding variables (age, sex, scholarly, physical activity, hypertension, and diabetes) were measured. Binary logistic regression analyzes the association of minimally and ultra-processed food consumption scores with OB (odds ratio [OR]). Results: minimally processed food consumption score quartiles (1st = 1[food-score/day]; 2nd = 6[food-score/day]; 3rd = 7[food-score/day]; 4th = 8[food-score/day]) presented higher values compared to ultra-processed food (1st = 1[food-score/day]; 2nd = 1[food-score/day]; 3rd = 2[food-score/day]; 4th = 4[food-score/day]). For each score of minimally processed food consumed, there was a -5.9 % odds of OB. Thus, the higher quartile (4th) of minimally processed food consumption score represents less odds of OB (OR: -47.2 %; p < 0.001). Each ultra-processed food score consumed presented odds of 3.7 % of OB. Therefore, higher consumption of ultra-processed food (4th quartile) shows higher odds of OB (OR: +14.8 %; p < 0.001). All associations remained significatively even after being adjusted by the confounders. Conclusion: the consumption scores of minimally processed and ultra-processed foods presented a magnitude capable of impacting OW adults' odds of OB, even when controlled by sociodemographic factors, physical activity, hypertension, and diabetes.
Introducción: Introducción: el tipo de alimentación representa una mayor probabilidad de tener obesidad (OB), especialmente en sujetos con sobrepeso (SO). Los alimentos mínimamente procesados y ultraprocesados se pueden asociar con las probabilidades de tener OB en sujetos con SO. Objetivo: investigar la asociación del consumo de alimentos mínimamente procesados y ultraprocesados con la OB en adultos con SO. Métodos: se incluyeron 15.024 participantes (9.618 SO [25,0-29,9 kg/m2], 5.406 OB [≥ 30 kg/m2]) con edades entre 18 y 59 años de la encuesta basal 2019 de la Vigilancia de Factores de Riesgo y Protección para Enfermedades Crónicas mediante una Encuesta Telefónica (VIGITEL, Brasil). Se midió el puntaje de consumo diario de alimentos mínimamente procesados y ultraprocesados y variables de confusión (edad, sexo, escolaridad, actividad física, hipertensión y diabetes). Mediante una regresión logística binaria se analizóla asociación de las puntuaciones de consumo de alimentos mínimamente procesados y ultraprocesados con la OB (odds ratio [OR]). Resultados: los cuartiles de puntuación de consumo de alimentos mínimamente procesados (1.º = 1[alimento-puntuación/día]; 2.º = 6[alimento-puntuación/día]; 3.º = 7[alimento-puntuación/día]; 4.º = 8[alimento-puntuación/día]) presentaron valores superiores en comparación con los alimentos ultraprocesados (1.º = 1[alimento-puntuación/día]; 2.º = 1[alimento-puntuación/día]; 3.º = 2[alimento-puntuación/día]; 4.º = 4[alimento-puntuación/día]). Por cada punto de alimentos mínimamente procesados consumidos, hubo una probabilidad de OB del -5,9 %. Por lo tanto, el cuartil más alto (4.º) de puntuación de consumo de alimentos mínimamente procesados representa menos probabilidades de OB (OR: -47,2 %; p < 0,001). Cada puntaje de alimentos ultraprocesados consumidos presentó probabilidades de 3.7 % de OB. Por lo tanto, un mayor consumo de alimentos ultraprocesados (cuartil 4.º) muestra mayores probabilidades de OB (OR: +14,8 %; p < 0,001). Todas las asociaciones se mantuvieron significativamente incluso después de ajustarlas por los factores de confusión. Conclusión:las puntuaciones de consumo de alimentos mínimamente procesados y ultraprocesados impactaron en la probabilidad de desarrollar OB en adultos con SB, incluso cuando se controló por factores sociodemográficos, actividad física, hipertensión y diabetes.

BACKGROUND: Examining the interrelationships between symptoms of depression and sociodemographic and behavioral correlates is challengeful using traditional regression analysis. OBJECTIVE: to identify the sociodemographic, movement behaviors, and sleep correlates that contribute the most to symptoms of depression in Brazilian older females, using a network analysis approach. METHODS: This cross-sectional study analyzed 1019 older females from Brazil. Data (sociodemographic, height (meters), weight (kilograms), symptoms of depression, physical activity, sleep) were self-reported via phone calls. The relationships between symptoms of depression and their correlates were assessed using the Network Analysis (qgraph package of the Rstudio) for entire sample and age groups (60-69; 70-79 and 80+ years old). RESULTS: 60-69 and 70-79 groups have more weekly home exits, with aging "single, widowed or divorced" was progressively higher, and "married or stable union" and Overweight/obesity were progressively fewer (p < 0.05). 60-69 have more education years and fewest medicaments use. Sleep compliance (for the entire sample), body mass index (for the 60-69), compliance with moderate to vigorous physical activity (for the 70-79), and educational level (for 80+) were the variables with the highest expected influence values (p < 0.05) on symptoms of depression (1.370; 1.388; 1.129; and 1.354, respectively). CONCLUSION: Symptoms of depression vary throughout the aging process and thus determine that intervention strategies encompass these specific factors according to each age group. Poor sleep behavior has a strong positive association with symptoms of depression. This result highlights that health professionals must be aware of the importance of sleep to mitigate the worsening of depression among older Brazilian females.

BACKGROUND: Handgrip strength (HGS) asymmetry is associated with slow gait speed. Both mark muscle dysfunction, potential risk of falls, and adverse health outcomes. This association was found in older adults from high-income countries, but not yet studied in low- and middle-income countries. Moreover, there is no HGS asymmetry referential to identify the disabling process. Thus, our study aims to verify the association of HGS asymmetry with slowness in older adults from six low- and middle-income countries and to propose cut points to slowness. METHODS: A cross-sectional study with data from 12,669 older adults (≥60 years) of the Study on Global Aging and Adult Health (SAGE) conducted in six low- and middle-income countries were analyzed. Based in the difference between upper body sides HGS (asymmetry), participants were categorized in groups as 0.0-10.0% (reference group), 10.1-20.1%, 20.1-30.0% or >30.0%. Slow gait speed was established as <0.59 (men) and <0.51 (women) m/s. Associations of HGS asymmetry with gait speed were ascertained with logistic regression. HGS asymmetry index "[(HGS asymmetry*HGS)/(BMI*Age)]*100" cut points to identify slowness were generated with the ROC curve and Youden index (α = 5%). RESULTS: Compared to HGS reference group, those with HGS asymmetry of 10.1-20%, 20.1-30.0% and >30.0% had a superior odds for slowness [1.18(CI:1.02,1.42); 1.17(CI: 0.97; 1.44); and 1.21(CI:1.03;1.43), respectively]. HGS asymmetry index cut points to identify slowness were ≤1.14 (women) and ≤1.77 (men). CONCLUSIONS: HGS asymmetry association with slowness is present in economically disadvantaged countries. We proposed a new index for impaired muscle function with acceptable sensibility and specificity.

The purposes of this systematic review and meta-analysis of peer-reviewed literature were to examine the chronic effects of resistance training with blood flow restriction (RT-BFR) on hemodynamics, and to compare these adaptations to those induced by traditional resistance training (TRT) programs in adults (PROSPERO: Registry: CRD42022339510). A literature search was conducted across PubMed, Sports Discus, Scielo, and Web of Science databases. Two independent reviewers extracted study characteristics and blood pressure measures. Risk of bias (The Cochrane risk of bias tool for randomized controlled trials [RoB-2]), and the certainty of the evidence (Grading of Recommendations, Assessment, Development, and Evaluation [GRADE]) were used. A total of eight studies met the inclusion criteria for systolic (SBP), diastolic (DBP), and mean arterial pressure (MAP). Regarding the comparison of RT-BFR vs. non-exercise, no significant differences favoring the exercise group were observed (p â> â0.05). However, when compared to TRT, RT-BFR elicited additional improvements on DBP (-3.35; 95%CI -6.00 to -0.71; I2 â= â14%; z â= â-2.48, p â= â0.01), and on MAP (-3.96; 95%CI -7.94 to 0.02; I2 â= â43%; z â= â-1.95, p â= â0.05). Results indicate that RT-BFR may elicit a decrease in DBP in comparison with TRT, but the lack of data addressing this topic makes any conclusion speculative. Future research on this topic is warranted.
ABSTRACT
BACKGROUND: Nutritional status, health risk behaviors, eating habits, and other comorbidities (such as diabetes) may be associated with recommended amounts of physical activity (PA) and exercise (EX) in healthy older adults. However, these associations are still unclear for older hypertensive adults, who require greater care from health professionals. The purpose of this study was to associate the nutritional status, health risk behaviors, eating habits, and the presence of diabetes with recommended amounts of physical activity and exercise practice of older hypertensive adults. METHODS: Ten thousand seven hundred eighty-nine older hypertensive adults (70.9 ± 7.4 years) from the VIGITEL telephone survey were classified according to PA levels (insufficiently active/sufficiently active) and EX practice (non-practitioners/practitioners). Binary logistic regression was used to observe the odds ratio (OR) between independent variables (nutritional status [body mass index], sociodemographic characteristics [age/sex/years of study], risk behaviors [screen time/alcohol/tobacco consumption], eating habits [minimally/ultra-processed foods consumption score], and the presence of diabetes) with recommended amounts of PA/EX (dependent variable). RESULTS: Highest nutritional status (ORPA = 0.975 [95%-CI: 0.965 - 0.985]; OREX = 0.981[95%-CI: 0.972 - 0.991]), age (ORPA = 0.955 [95%-CI: 0.949 - 0.961]; OREX = 0.980[95%-CI: 0.975 - 0.986]), screen time (ORPA = 0.909[95%-CI: 0.835 - 0.990]), alcohol consumption (ORPA = 0.683[95%-CI: 0.621 - 0.758]; OREX = 0.702[95%-CI: 0.637 - 0.779]), tobacco (ORPA = 0.601 [95%-CI: 0.492 - 0.736]; OREX = 0.464[95%-CI: 0.384 - 0.562]) ultra-processed foods consumption score (ORPA = 0.896[95%-CI: 0.871 - 0.921]; OREX = 0.886[95%-CI: 0.863 - 0.909]) and having diabetes (ORPA = 0.780[95%-CI: 0.708 - 0.859]; OREX = 0.831[95%-CI: 0.759 - 0.909]) reduced the odds of being sufficiently active/practicing exercise (p < 0.05). Male sex (ORPA = 1.633[95%-CI: 1.491 - 1.789]; OREX = 1.247[95%-CI: 1.140 - 1.363]), years of study (ORPA = 1.026[95%-CI: 1.018 - 1.035]; OREX = 1.050[95%-CI: 1.041 - 1.058]), and minimally processed foods consumption score increased the odds of being sufficiently active/practicing exercise (ORPA = 1.132[95%-CI: 1.109 - 1.155]; OREX = 1.167[95%-CI: 1.145 - 1.191], respectively; p < 0.05). CONCLUSION: Nutritional status, health risk behaviors, eating habits, and the presence of diabetes were associated with the odds of older hypertensive adults complying with PA and EX recommendations. The results may help health professionals understand how these factors are associated with the changes of older hypertensive adults participating in physical activity and exercise.

The regular practice of physical activity helps in the prevention and control of several non-communicable diseases. However, evidence on the role of physical activity in mitigating worsening clinical outcomes in people with COVID-19 is still unclear. The aim of this study was to verify whether different levels of physical activity provide protection for clinical outcomes caused by SARS-CoV-2 infection. A cross-sectional study was conducted with 509 adults (43.8 ± 15.71 years; 61.1% female) with a positive diagnosis of COVID-19 residing in Ribeirão Preto, São Paulo, Brazil. Participants were interviewed by telephone to determine the severity of the infection and the physical activity performed. Binary logistic regression was used to indicate the odds ratio (OR) of active people reporting less harmful clinical outcomes from COVID-19. Active people had a lower chance of hospitalization, fewer hospitalization days, less respiratory difficulty and needed less oxygen support. The results suggest that active people, compared to sedentary people, have a lower frequency of hospitalization, length of stay, breathing difficulty and need for oxygen support. These results corroborate the importance of public policies to promote the practice of physical activity, in order to mitigate the severity of the clinical outcomes of COVID-19.
