Gender Gap for Accelerometry-Based Physical Activity Across Different Age Groups in 5 Brazilian Cohort Studies.

OBJECTIVES: This study aims to evaluate the gender inequalities in accelerometer-based physical activity (PA) across different age groups using data from 5 Pelotas (Brazil) cohorts. METHODS: The data come from 4 birth cohort studies, covering all live births in the urban area of Pelotas for each respective year (1982, 1993, 2004, and 2015), and the Como vai? cohort study focusing on 60 years and above. Raw accelerometry data were collected on the nondominant wrist using GENEActive/ActiGraph devices and processed with the GGIR package. Overall PA was calculated at ages 1, 2, 4, 6, 11, 15, 18, 23, 30, and 60+ years, while moderate to vigorous PA was calculated from 6 years onward. Absolute (difference) and relative (ratio) gender inequalities were calculated and intersectionality between gender and wealth was also evaluated. RESULTS: The sample sizes per cohort ranged from 965 to 3462 participants. The mean absolute gender gap was 19.3 minutes (95% confidence interval, 12.7-25.9), with the widest gap at 18 years (32.9 min; 95% confidence interval, 30.1-35.7) for moderate to vigorous PA. The highest relative inequality was found in older adults (ratio 2.0; 95% confidence interval, 1.92-2.08). Our intersectionality results showed that the poorest men being the most active group, accumulating around 60 minutes more moderate to vigorous PA per day compared with the wealthiest women at age 18. CONCLUSIONS: Men were more physically active than women in all ages evaluated. PA gender inequalities start at an early age and intensify in transition periods of life. Relative inequalities were marked among older adults.

[Body image and associated factors among students from the municipal school network in a city in southern Brazil]. / Imagem corporal e fatores associados em estudantes da rede municipal de ensino em uma cidade no sul do Brasil.

A negative perception of body image is related to worsening of physical and mental health. This cross-sectional study sought to describe the relationship between body image and demographic, socioeconomic and behavioral factors in ninth grade students from 25 municipal elementary schools in Pelotas, Rio Grande do Sul. A total of 810 students participated (85% of those eligible), aged 13 to 22 years (mean age 14.9 years). Data were collected through a standardized and pre-coded questionnaire and the relationship between the outcome (satisfied/indifferent or dissatisfied with body image), and independent variables were analyzed using Multinomial Logistic Regression. The prevalence of body dissatisfaction of 31%, higher among girls who tried smoking or alcohol, suffered bullying, perceived themselves as fat/thin and tried to lose/gain weight. There was greater indifference among those who attributed little or no importance to image. In boys, there was a higher incidence of dissatisfaction among those who tried smoking, suffered bullying, gave little/no importance to image, saw themselves as fat and tried to gain weight. There was greater indifference in boys who attributed little importance to image and were obese. A third of the sample were dissatisfied, which was associated with various behavioral factors.

A percepção negativa da imagem corporal está relacionada à piora da saúde física e mental. Estudo transversal objetivou descrever a relação entre imagem corporal e fatores demográficos, socioeconômicos e comportamentais nos estudantes do nono ano de 25 escolas municipais de ensino fundamental em Pelotas, Rio Grande do Sul. Participaram 810 estudantes (85% dos elegíveis), de 13 a 22 anos (média de 14,9 anos). Dados foram coletados mediante questionário padronizado e pré-codificado e a relação entre o desfecho (estar satisfeito, indiferente ou insatisfeito em relação à imagem corporal), e variáveis independentes, foi analisada por Regressão Logística Multinomial. Prevalência de insatisfação corporal de 31%, maior entre as meninas que experimentaram fumo ou álcool, sofreram bullying, se percebiam como gordas ou magras e tentavam perder ou ganhar peso. Maior indiferença nas que atribuíram pouca ou nenhuma importância à imagem. Nos meninos, mais chances de insatisfação entre os que experimentaram fumo, sofreram bullying, atribuíram pouca ou nenhuma importância à imagem, se percebiam gordos e tentavam ganhar peso. Maior indiferença nos meninos que atribuíram pouca importância à imagem e estavam obesos. Cerca de um terço da amostra apresentou insatisfação, que esteve associada a alguns fatores comportamentais.

Standardized phase angle: relationship with functionality, muscle mass and postoperative outcomes in surgical cancer patients.

To evaluate the association of standardized phase angle (SPA) with nutritional status, functional parameters, and postoperative outcomes in surgical cancer patients. This prospective study includes 59 cancer patients from Pelotas (Brazil) admitted for elective cancer surgery. We obtained the phase angle through Bioelectrical Impedance Analysis (BIA) and standardized it according to the population's reference values. We estimated the muscle mass using BIA for later calculation of the Skeletal Muscle Index (SMI) and performed handgrip strength (HGS) and gait speed (GS) tests. We used the Patient-Generated Subjective Global Assessment (PG-SGA) to assess the nutritional status. Postoperative complications and duration of hospital stay were evaluated as the outcomes. The prevalence of malnutrition in the sample was 28.8%, according to ASG-PPP. SPA was statistically lower in patients with malnutrition, with lower HGS and reduced GS. For postoperative outcomes, patients with severe complications and those with prolonged hospitalization also had lower SPA values. The greater the number of functional alterations in patients, the lower the SPA value, mainly when associated with reduced muscle mass assessed by BIA, suggesting that muscle mass reduction plays an important role in the association between functional alterations and phase angle in patients with cancer. According to the parameters used in this study, low SPA value was associated with impaired nutritional and functional status and negative outcomes in the analyzed sample.

Resistance training presents beneficial effects on bone development of adolescents engaged in swimming but not in impact sports: ABCD Growth Study.

BACKGROUND: Sports practice during adolescence is important to enhance bone development, although it may provide different effects depending on the mechanical impact present in the sport. Besides, resistance training (RT) may also induce bone changes directly (via muscle contractions) and indirectly (via myokines). However, there have been no studies analyzing the longitudinal influence of engaging in sport with and without added mechanical load. Thus, this study aims to analyze the combined effects of sports participation and resistance training on areal bone mineral density (aBMD) accrual in adolescent athletes participating in swimming and impact sports for 12-months. METHODS: This was a 12-month longitudinal study. The sample comprised 91 adolescents (21 females) aged 10 to 18 years, engaged in impact sports (basketball, tennis, track & field, baseball and gymnastics, n = 66) and non-impact sport (swimming, n = 25). The sample was divided according to resistance training participation: impact sports only (n = 45), impact sports + resistance training (n = 21), swimming-only (n = 17) and swimming + resistance training (n = 8). aBMD and soft tissues were measured using dual-energy X-ray absorptiometry. Generalized linear models analysis was used for the resistance training (RT) x type of sport interaction in predicting aBMD changes overtime, adjusting for maturation, sex and baseline aBMD. RESULTS: After 12-months, all groups showed a significant increase in aBMD, except for the swimming groups (regardless of resistant training), which showed a significant loss in spine aBMD (-0.045 [-0.085 to -0.004] g/cm2 in swimming-only and - 0.047 [-0.073 to -0.021] g/cm2 in swimming + RT). In comparisons between groups, only swimming + RT group, compared with swimming-only group presented higher upper limbs aBMD (0.096 g/cm2 [0.074 to 0.118] in swimming + RT vs. 0.046 [0.032 to 0.060] g/cm2 in swimming only; p < 0.05) and whole body less head (WBLH) aBMD (0.039 [0.024 to 0.054] g/cm2 in swimming + RT vs. 0.017 [0.007 to 0.027] g/cm2 swimming-only; p < 0.05). CONCLUSION: Despite the significant gain in aBMD in all groups and body sites after 12-months, except for the spine site of swimmers, the results indicate that participation in RT seems to improve aBMD accrual in swimmers at the upper limbs and WBLH.

Low Physical Performance Could Be Associated with Adverse Health Outcomes over Time: Results from a Cohort of Older Adults.

A few studies on physical performance (PP) decline among community-dwelling older adults have simultaneously evaluated various outcomes in Brazil. This longitudinal cohort study aimed to verify the association between PP and health outcomes (negative health self-perception-NHSP; consultations with health professionals; disability; falls; and hospitalization) in older Brazilians (N = 476, 68 ± 6.7 years). PP assessments included Gait Speed (GS) and Timed Up and Go (TUG) tests, and changes were evaluated over time (2014 to 2019-2020). The association between the PP and the outcomes was estimated using Poisson's regression with robust variance. The physical tests were not associated with NSPH or with the number of consultations with health professionals. However, after adjustment (economic level, diet quality, physical activity, multimorbidity, depression, polypharmacy, and BMI), low PP at baseline (TUG and GS) was associated with disability at follow-up. A low TUG performance at baseline was also associated with subsequent falls (PR = 1.57, p = 0.007). A decline in GS was associated with hospitalization (PR = 1.86, p = 0.033). PP was associated with disability, falls, and hospitalization over a five- to six-year period in older Brazilians. Regular PP assessments should be conducted and low PP should be used as an indicator of the need for preventative measures to avoid poor health outcomes.

Is rest-activity rhythm prospectively associated with all-cause mortality in older people regardless of sleep and physical activity level? The 'Como Vai?' Cohort study.

OBJECTIVE: This study aims to test the association of rest-activity rhythm (intradaily variability and interdaily stability) with all-cause mortality in an older adult cohort in Brazil. It also assesses whether the amount of time spent at each intensity level (i.e., physical activity and nocturnal sleep) interferes with this association. METHODS: This cohort study started in 2014 with older adults (≥60 years). We investigated deaths from all causes that occurred until April 2017. Rest-activity rhythm variables were obtained using accelerometry at baseline. Intradaily variability indicates higher rhythm fragmentation, while interdaily stability indicates higher rhythm stability. Cox proportional-hazard models were used to test the associations controlling for confounders. RESULTS: Among the 1451 older adults interviewed in 2014, 965 presented valid accelerometry data. During the follow-up period, 80 individuals died. After adjusting the analysis for sociodemographic, smoking, morbidity score, and number of medicines, an increase of one standard deviation in interdaily stability decreased 26% the risk of death. The adjustment for total sleep time and inactivity did not change this association. On the other hand, the association was no longer significant after adjusting for overall physical activity and moderate to vigorous physical activity. CONCLUSION: Rest-activity rhythm pattern was not associated with mortality when physical activity was considered, possibly because this pattern could be driven by regular exercise. Promoting physical activity remains a relevant strategy to improve population health.

[Bullying victimization and associated factors among schoolchildren in a city in the south of Brazil]. / Vitimização por bullying e fatores associados entre escolares de um município do Sul do Brasil.

The objective was to assess the prevalence of bullying victimization and associated factors among adolescents in the city of Pelotas, Rio Grande do Sul. A cross-sectional school-based study was conducted with 795 ninth grade students from 25 urban municipal schools linked to the School Health Program. Bullying was assessed using questions that addressed the occurrence, frequency, location, type of violence suffered and how much it bothers the victims. Gross and adjusted analyses were performed by Poisson regression. Approximately 71% of the students reported having suffered bullying, and school was the location of greatest occurrence (86.7%). Among the types of aggression suffered, "nicknames" was the most recurrent complaint (88.4%), followed by exclusion or isolation (26.6%). Victimization was more frequent among girls (PR 1.13; 95%CI 1.02-1.27), students with non-white skin color/race (PR 1.16; 95%CI 1.05-1.29), who have already tried tobacco (PR 1.14; 95%CI 1.03-1.27), dissatisfied (PR 1.42; 95%CI 1.27-1.58) or indifferent (PR 1.21; 95%CI 1.02-1.43) about their bodies, and who were overweight (PR 1.15; 95%CI 1.04-1.27). The results show that bullying is a frequent practice in the school environment, pointing to the need for educational practices aimed at reducing and preventing this type of violence.

Self-perception of need to replace dentures and oral health-related quality of life: cross-sectional study nested in a Cohort in Southern Brazil

Aim: With the significant increase in life expectancy over the last decades, it is important to understand how oral health can impact the oral health-related quality of life of older adults. This study aimed to investigate the association between need to replace dentures and oral health-related quality of life (OHRQoL) among older adults belonging to a Cohort in southern Brazil. Methods: This cross-sectional study was conducted with data from the 2019 Pelotas Elderly Cohort. The OHRQoL was assessed using the GOHAI. Need to replace dentures was self-report using a question dichotomized into yes/no. In the statistical analysis, unadjusted and adjusted models estimate from linear regression models were calculated. The significance level adopted was 5%. Results: A total of 493 older adults were included. On the GOHAI questionnaire, the mean score was 32.74 (SD±0.16). Individuals considering need of prosthesis replacement were 47.89%. Report of need to replace dentures was associated to lowest mean on the GOHAI score (ß -1.14; 95%CI - 1.80; -0.478, and on the physical (ß -0.56; 95%CI - 0.94 -0.17) and psychosocial (ß -0.48; 95%CI - 0.74; -0.22) dimensions. Conclusion: Our findings highlight the importance of also considering subjective measures of oral health in the dental care of older adults, since reporting the need for denture replacement, regardless of the reason, was associated with a worse oral health-related quality of life, including physical and psychosocial aspects

Price elasticity of demand for ready-to-drink sugar-sweetened beverages in Brazil.

The taxation of sugar-sweetened beverages is a policy that has been adopted in many countries worldwide, including Latin American, to reduce sugar consumption. However, little is known about how taxation on these products may affect their demand. The present study aims to estimate the price elasticity of demand for sugar-sweetened beverages in Brazil. This study advances the literature by proposing a breakdown between ready-to-drink sugar-sweetened beverages and sugar-sweetened beverages that require some preparation before being consumed. With this disaggregation, it is possible to obtain more accurate elasticities for the group of products that will be effectively taxed. We estimated a Quadratic Almost Ideal Demand System (QUAIDS) model using the Household Budget Survey 2017-2018 microdata. The results show that ready-to-drink beverages is more consumed but less sensitive to changes in price than prepared beverages. The price elasticity of demand for ready-to-drink and prepared sugar-sweetened beverages was -1.19 and -3.38. Additionally, we observe heterogeneity in these price elasticities across household incomes, with a more elastic demand among lower-income households for ready to drink beverages. The findings suggest that taxing ready-to-drink sweetened beverages could potentially reduce sugar consumption directly through a decrease in the consumption of sugary drinks and this effect could be reinforced by reducing the consumption of other sugar-rich products. Therefore, the taxation police should effective contribute to minimize health risks associated to the sugar consumption.

Validation of dysphagia perception to predict the risk for dysphagia in non-institutionalized older adults.

BACKGROUND AND AIMS: Dysphagia is a swallowing disorder that affects mainly the older adults and can compromise quality of life, and increase the risk for malnutrition and aspiration. Early diagnosis is, therefore, essential to prevent adversities. We aimed to evaluate the validity of self-perceived dysphagia in community-dwelling older adults (60 years or older) from Pelotas, Brazil, participants in the "COMO VAI?" METHODS: The Eating Assessment Tool (EAT-10) was used as the reference tool to identify the risk for dysphagia and the self-perception of dysphagia was assessed using the following question: "Do you have swallowing difficulties?" (Yes/No). The parameters of sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy were described with 95% confidence intervals (95% CI) and according to independent variables (sex, age, economic level, and education). RESULTS: The prevalence of dysphagia risk according to EAT-10 and self-perception was 12.9% (95% CI 10.2-16.1) and 8.8% (95% CI 6.6-11.6), respectively. Sensitivity was 34.8% (95% CI 23.5-47.6) and the highest values were observed in women and the older individuals (80 years or older). Specificity was 95.1% (95% CI 92.6-96.9). PPV was 51.1% (95% CI 35.8-66.3), NPV 90.8% (95% CI 87.8-93.2) and accuracy 87.3%. CONCLUSIONS: Considering the low sensitivity and PPV, the self-perception of dysphagia analyzed with a single question should be used with caution, as an individual at risk for dysphagia may not realize their condition.

Healthy eating markers among adolescents from the municipal school system in Pelotas, Rio Grande do Sul, Brazil, 2019: a cross-sectional study.

MAIN RESULTS: Around 3% of the students regularly consumed the five healthy eating markers, with beans being the most frequently consumed; strong association was found between healthy eating markers and behavioral variables. Implications for services: The results obtained can contribute for interventions, programs and actions, particularly in the school environment, aimed at promoting an adequate and healthy diet. PERSPECTIVES: Better targeting of interventions, programs and actions developed in the school environment, seeking to increase consumption of fresh and minimally processed food, along with the adoption of healthy behaviors. OBJECTIVE: to analyze the consumption of healthy eating markers among adolescent students in Pelotas, Rio Grande do Sul, Brazil, in 2019. METHODS: this was a cross-sectional study carried out in schools taking part in the Health at School Program. Consumption of the five markers (beans, milk, fruit, cooked vegetables and raw salads) within five days prior to the study, obtained through a self-administered questionnaire, was defined as regular. Association between demographic, socioeconomic and behavioral variables and the outcomes was analyzed using Poisson regression. RESULTS: among the 797 respondents, 2.8% (95%CI 1.8;4.1) reported regular consumption. Beans were the most regularly consumed food (48.3%); fruit, cooked vegetables and raw salads were consumed regularly by less than 30% of the students. Doing physical activities, having breakfast and having meals with the family were associated with regular consumption of the foods assessed. CONCLUSION: regular consumption of healthy foods was low in this population, and was associated with behavioral factors.

[Prevalence of water intake among non-institutionalized elderly individuals in Southern Brazil]. / Prevalência de ingestão hídrica e fatores associados entre idosos não institucionalizados do Sul do Brasil.

The scope of this study was to determine the percentage of elderly individuals receiving an adequate water intake and associated factors among non-institutionalized elderly individuals in the urban area of Pelotas, Rio Grande do Sul. It involved a cross-sectional, population-based study carried out in 2014 with elderly participants (≥ 60 years) of the "COMO VAI?" survey. The amount of water ingested per day of the interviewees was investigated, considering the intake of at least eight glasses per day to be adequate. The independent variables were sociodemographic, behavioral, and health characteristics, and Poisson Regression was used to investigate associations. A total of 1,451 elderly people were interviewed, with only 12.6% (95%CI 10.8; 14.7) drinking a sufficient amount. A higher percentage of the elderly with adequate water consumption was observed in younger elderly individuals, those overweight, those with five or more diseases, and those who were more impaired. A low percentage of the elderly with an adequate water intake was observed among the elderly adults in the study. The decreasing trend of water intake in relation to age highlights the importance of developing actions for the higher risk population to stress adequate water intake and the possible consequences of the lack of adequate consumption.

O objetivo deste estudo foi descrever a prevalência de idosos com uma ingestão adequada de água e seus fatores associados. Estudo transversal de base populacional realizado em 2014 com idosos (≥ 60 anos) participantes do estudo "COMO VAI?". Investigou-se o número de copos de água ingeridos/dia pelos entrevistados, considerando-se adequada a ingestão de pelo menos oito copos/dia. As variáveis independentes foram características sociodemográficas, comportamentais e de saúde. A regressão de Poisson foi utilizada para a investigação das associações. Foram entrevistados 1.451 idosos, sendo observado que uma baixa percentagem, 12,6% (IC95% 10,8; 14,7) referiu consumo adequado de água. Maior percentagem de consumo adequado de água foi observada nos idosos mais jovens, com excesso de peso, que apresentaram cinco ou mais doenças e que eram mais dependentes quanto à capacidade funcional. A tendência decrescente de ingestão de água em relação à idade torna essencial o desenvolvimento de ações voltadas para essa população de maior risco acerca da importância de uma ingestão hídrica adequada e das possíveis consequências do seu consumo inadequado.

Functional dentition and edentulism associated with mortality: A cohort study of older adults in Southern Brazil.

OBJECTIVE: The aim of this study was to evaluate the association between the lack of a functional dentition and edentulism with mortality in a cohort of older adults in a Southern Brazilian city. MATERIALS AND METHODS: This is a longitudinal study carried out with community-dwelling older adults (≥60 years old) from Pelotas, Brazil, using data from the baseline (2014) and the first follow-up (2017). Main exposures were functional dentition (20+ teeth present) and edentulism (absence of all teeth), derived from self-reported number of teeth. All-causes mortality was evaluated according to the city's Epidemiological Surveillance Department. Potential confounders were age, sex, socioeconomic position, smoking, diabetes, hypertension, and body mass index (BMI). To test the association between functional dentition and edentulism with mortality, Poisson regression models with robust variance were used, to estimate Relative Risks and 95% confidence intervals. RESULTS: A total of 1289 older adults had information on all variables of interest and comprise the analytical sample (from 1451 at baseline). When analysing the presence of functional dentition, only 222 individuals (17.2%) had 20 or more teeth in their mouth, while 490 older adults were edentulous (38.0%). Crude analysis showed an association between tooth loss indicators and mortality. Models adjusted for sociodemographic variables and health conditions and behaviours revelled no association between the exposures and mortality. CONCLUSIONS: With the findings of this study, we did not identify an association between edentulism and functional dentition with mortality, after considering important shared risk factors.

Changes in Physical Performance among Community-Dwelling Older Adults in Six Years.

Changes in physical performance (PP) occur with aging, and understanding the magnitude of these changes over time is important. This study evaluated changes in Gait Speed (GS) and Timed Up and Go (TUG) performance and their association with related factors among community-dwelling older adults over a period of five to six years. A cohort study of 476 older adults with baseline assessment conducted in 2014 and reassessment in 2019-2020 was carried out. Associations between PP changes over time and sociodemographic, behavioral, and health variables were evaluated using mixed linear models. Approximately 68% of the participants declined PP; 20% had no relevant change in GS and 9% in TUG time (sustained PP); 12% increased GS, and 23% decreased TUG time (improved PP). Being male (p = 0.023), living without a partner/separated (p = 0.035), higher education (p = 0.019), and alcohol consumption in the prior month (p = 0.045) were associated with decreased GS, while older age (p < 0.001), having lower socioeconomic status (p < 0.004), physical inactivity (p = 0.017), and being overweight (p = 0.007) were associated with increased TUG time. PP declined for most participants. Factors most strongly associated with PP decline are non-modifiable. The high prevalence of PP decline over time signals the importance of including physical tests in yearly health assessments.

Muscle Quality in Older Adults: A Scoping Review.

OBJECTIVE: This scoping review aimed to map out currently available definitions and assessment methods of muscle quality in older adults. DESIGN: Scoping review. SETTING AND PARTICIPANTS: All available studies. METHODS: Four databases (PubMed, EMBASE, Web of Science, and Cochrane Library) were searched from inception to May 2022. Title, abstract, and full-text screening were undertaken by 2 reviewers independently. Observational and experimental studies were eligible for inclusion if there was a clear description of muscle quality assessment in individuals aged 60+ years. RESULTS: A total of 96 articles were included. Several definitions and assessment methods of muscle quality were identified and divided into 2 main domains: (1) functional domain, and (2) morphological domain. A total of 70% and 30% of the included studies assessed muscle quality in the functional and morphological domains, respectively. In the functional domain, most studies defined muscle quality as the ratio of knee extension strength by leg lean mass (45.9%). In the morphological domain, most studies defined muscle quality as the echo intensity of quadriceps femoris by ultrasound (50.0%). CONCLUSIONS AND IMPLICATIONS: There is a substantial heterogeneity of definitions and assessment methods of muscle quality in older adults. Herein, we propose a standardized definition of muscle quality to include terminology, domain, and assessment methods (tests, tools, and body sites). Such standardization may help researchers, clinicians, and decision makers use muscle quality as a potential marker of "skeletal muscle health" in older adults.

Age is the most important factor for change in body mass index and waist circumference in older people in southern Brazil.

OBJECTIVES: The aim of this study is to assess the changes in body mass index and waist circumference (WC) and their associations with sociodemographic, behavioral, and health characteristics in non-institutionalized older people in southern Brazil over a period of ≤6 y. METHODS: This is a prospective study, with interviews conducted in 2014 and in 2019 to 2020. Of the 1451 individuals from Pelotas, Brazil, aged >60 y and interviewed in 2014, 537 were reevaluated in 2019 to 2020. An increase or decrease was defined as a variation of ≥5% in body mass index and WC in the second visit compared with the first. The association with changes in outcomes was assessed according to sociodemographic, behavioral, and health characteristics using multinomial logistic regression. RESULTS: Approximately 29% of the older participants lost body mass. Regarding WC, there was an increase in 25.6% in the older participants. The older participants ages ≥80 y had greater odds of losing body mass (odds ratio [OR] = 4.73; 95% confidence interval [CI], 2.29-9.76) and of reducing WC (OR = 2.84; 95% CI, 1.59-6.94). Former smokers had, on average, 41% and 64% lower odds of losing and gaining body mass (95% CI, 0.37-0.95 and 95% CI, 0.19-0.68, respectively), and those who were on ≥5 medications had greater odds of gaining body mass (OR = 1.92; 95% CI, 1.12-3.28) and WC (OR = 1.79; 95% CI, 1.18-2.74). CONCLUSIONS: Despite the high proportion of older people who kept their body mass index and WC stable during this period, many of them lost body mass and gained WC. The findings also highlighted the importance of age in the nutritional changes observed in the population.
