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.

[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.

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.

[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.

O objetivo foi avaliar a prevalência de vitimização por bullying e seus fatores associados entre adolescentes da cidade de Pelotas, RS. Estudo transversal de base escolar realizado com 795 alunos do 9o ano do ensino fundamental de 25 escolas municipais urbanas vinculadas ao PSE. O bullying foi avaliado por meio de perguntas que abordaram a ocorrência, a frequência, o local, o tipo de violência sofrida e o quanto isso incomoda as vítimas. Análises bruta e ajustada foram feitas por regressão de Poisson. Aproximadamente 71% dos estudantes relataram ter sofrido bullying, a escola foi o local de maior ocorrência (86,7%). Entre os tipos de agressões sofridas, "apelidos" foi a queixa mais recorrente (88,4%), seguida por exclusão ou isolamento (26,6%). A vitimização foi mais frequente entre as meninas (RP 1,13; IC95% 1,02-1,27), estudantes com cor da pele/raça não branca (RP 1,16; IC95% 1,05-1,29), que já experimentaram tabaco (RP 1,14; IC95% 1,03-1,27), insatisfeitos (RP 1,42; IC95% 1,27-1,58) ou indiferentes (RP 1,21; IC95% 1,02-1,43) em relação ao corpo e que apresentavam excesso de peso (RP 1,15; IC95% 1,04-1,27). Os resultados mostram que o bullying é uma prática frequente no ambiente escolar, apontando para a necessidade de práticas educativas voltadas para a redução e prevenção desse tipo de violência.

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.

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

Resumo 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.

Abstract 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.

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.

Prática de atividade física e desigualdades em idosos antes e após a COVID-19 / Physical activity and inequalities in older adults before and after COVID-19

O objetivo do estudo foi verificar modificações na prevalência de atividade física (AF) e desigual-dades em idosos acompanhados antes e após o período de distanciamento social causado pela CO-VID-19. Trata-se de estudo prospectivo conduzido na zona urbana da cidade de Pelotas-Rio Grande do Sul, onde idosos foram acompanhados no ano de 2019/20 e 2021/22. A prevalência de AF foi avaliada através do IPAQ nos domínios do lazer e deslocamento avaliados de forma conjunta. Foram classificados como ativos fisicamente aqueles que realizavam ≥ 150 min/sem. As covariáveis/estra-tificadores avaliadas foram sexo, idade, cor da pele, classe econômica, escolaridade e morbidades. As desigualdades simples foram avaliadas através das diferenças e das razões da prevalência de AF e as desigualdades complexas através do índice de desigualdade (SII) e o índice de concentração (CIX). Os resultados indicaram que houve redução da prevalência de AF de 2019/20 para 2021/22 e que essas modificações ocorreram em todos os grupos populacionais, variando em termos de magnitude de declínio. O SII mostrou aumento da desigualdade entre os mais pobres em comparação aos mais ricos e redução da desigualdade em relação à idade, escolaridade e morbidades. Concluiu-se que a redução da AF ocorreu em todos os grupos populacionais. Em termos de desigualdades, houve aumento em termos de classe econômica e, nos casos de redução da desigualdade, tal mudança foi em virtude da diminuição de AF entre as categorias que eram mais ativas, sendo necessário políticas de saúde para resgatar níveis adequados de AF na população estudada

This study aimed to verify the modification in the physical activity prevalence (PA) and possible inequalities in older individuals monitored before and after social distancing due to COVID-19. This is a prospective study conducted in the urban area of Pelotas-Rio Grande do Sul, where the elderly was followed up in 2019/20 and 2021/22. The prevalence of PA was assessed using the IPAQ in the domain of leisure time and commuting evaluated together. Older people who performed ≥150 min/week were classified as physically active. The covariates/stratifiers assessed were sex, age, skin color, economic class, schooling, and morbidity. Simple inequalities were assessed through differences and ratios for the prevalence of PA and complex ine-qualities through the inequality index (SII) and the concentration index (CIX). The results indicated that there was a reduction in the prevalence of PA among the participants from 2019/20 to 2021/22 and that these changes occurred regardless of population characteristics. The SII showed an increase in PA inequality among the poorest compared to the richest individuals and a reduction in inequalities about age, education, and morbidities. It is concluded that the reduction in PA occurred similarly regardless of the covariates/stratifiers evaluated, that there was an increase in inequality in PA among the less economically favored, and that the reduction in inequality occurred especially from the reduction in PA, requiring health policies to rescue adequate levels of PA in the studied population

Dificuldades no uso de medicamentos por idosos acompanhados em uma coorte do Sul do Brasil / Difficulties in the use of medications by elderly people followed up in a cohort study in Southern Brazil

RESUMO Objetivo: Este estudo visou avaliar a necessidade de ajuda dos idosos para tomar seus medicamentos, bem como as dificuldades relacionadas com a sua utilização, e a frequência de esquecimento de doses. Ainda, avaliar fatores associados à necessidade de ajuda dos idosos com os medicamentos. Métodos: Corte transversal em uma coorte de idosos (60 anos ou mais — estudo "COMO VAI?"), em que foi avaliada a necessidade de ajuda para tomar medicamentos de forma adequada e as dificuldades apresentadas na sua utilização. Utilizou-se regressão de Poisson para estimar as razões de prevalência (RP) brutas e ajustadas dos desfechos e seus intervalos de confiança de 95% (IC95%) de acordo com as características da amostra. Resultados: Participaram 1.161 idosos. A prevalência de idosos que relataram necessidade de ajuda com os medicamentos foi de 15,5% (IC95% 13,5-17,8), sendo que os mais idosos, com menor escolaridade e em pior situação econômica, em uso de quatro medicamentos ou mais e com pior autoavaliação de saúde foram os que mais necessitaram de ajuda. O uso contínuo de medicamentos foi referido por 83,0% (IC95% 80,7-85,1) e a maioria (74,9%; IC95% 72,0-77,5) nunca se esqueceu de tomar seus medicamentos. Conclusão: Observou-se a influência de determinantes sociais e econômicos e de saúde sobre a necessidade de ajuda para a utilização dos medicamentos. Estudos que estimem as dificuldades no uso de medicamentos por idosos são importantes para subsidiar políticas e práticas norteadoras de ações para melhorar a adesão e o uso racional de medicamentos.

ABSTRACT Objective: This study aimed to assess the need for help by elderly people to take their medications, the difficulties related to this activity, the frequency of forgotten doses, and factors associated. Methods: Cross-sectional study conducted with a cohort of elderly people (60 years and over — "COMO VAI?" [How do you do?] study), where the need for help to properly take medication and the difficulties faced in using them were evaluated. The Poisson regression model was used to estimate the crude and adjusted prevalence ratios (PR) of the outcomes and respective 95% confidence intervals according to the characteristics of the sample. Results: In total, 1,161 elderly people were followed up. The prevalence of participants who reported requiring help with medication was 15.5% (95%CI 13.5-17.8), and the oldest subjects, with lower educational levels, in worse economic situations, on four or more medications and in bad self-rated health were the ones who needed help the most. Continuous use of medication was reported by 83.0% (95%CI 80.7-85.1) of the sample and most participants (74.9%; 95%CI 72.0-77.5) never forgot to take their medications. Conclusion: The need for help to use medications was shown to be influenced by social and economic determinants. Studies assessing the difficulties in medication use by the elderly are important to support policies and practices to improve adherence to treatment and the rational use of medications.

Marcadores de alimentação saudável entre adolescentes da rede municipal de ensino de Pelotas, Rio Grande do Sul, 2019: estudo transversal / Healthy eating markers among adolescents from the municipal school system in Pelotas, Rio Grande do Sul, Brazil, 2019: a cross-sectional study / Marcadores de alimentación saludable entre adolescentes del sistema escolar municipal de Pelotas, Rio Grande do Sul, Brasil, 2019: estudio transversal

Objetivo: analisar o consumo de marcadores de alimentação saudável entre adolescentes escolares de Pelotas, Rio Grande do Sul, Brasil, em 2019. Métodos: estudo transversal, realizado nas escolas vinculadas ao Programa Saúde na Escola; o consumo dos cinco marcadores (feijão, leite, frutas, vegetais cozidos, saladas cruas) em até cinco dias antecedentes ao estudo, obtido mediante questionário autoaplicado, foi definido como regular; a associação de variáveis demográficas, socioeconômicas e comportamentais com os desfechos foi analisada por regressão de Poisson. Resultados: entre os 797 entrevistados, 2,8% (IC95% 1,8;4,1) referiram consumo regular; o feijão foi o alimento mais consumido regularmente (48,3%); frutas, vegetais cozidos e saladas cruas foram consumidos regularmente por menos de 30% dos escolares; praticar atividade física, tomar café da manhã e realizar refeições com a família estiveram associados ao consumo regular dos alimentos avaliados. Conclusão: o consumo regular de alimentos saudáveis, encontrado baixo nessa população, associou-se com fatores comportamentais.

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.

Resultados: entre los 797 encuestados, el 2,8% (IC95% 1,8; 4,1) informó un consumo regular. Los porotos fueron el alimento más consumido (48,3%). Frutas, verduras cocidas y ensaladas crudas fueron consumidas regularmente por menos del 30% de los estudiantes. La práctica de actividad física, el desayuno y las comidas en familia se asociaron con mayor consumo de los alimentos evaluados. Conclusión: el consumo regular de alimentos saludables fue bajo en esta población y se asoció con factores conductuales.

Tipos de leite consumidos durante o primeiro ano de vida e estado nutricional de lactentes do Sul do Brasil / Types of milk consumed during the first year of life and nutritional status of infants in Southern Brazil

Resumo Introdução A Organização Mundial da Saúde (OMS) recomenda o aleitamento materno exclusivo até o 6º mês de vida da criança e a sua manutenção com alimentação complementar até pelo menos os 2 anos de idade. Apesar da sua importância, a ingestão de substitutos do leite materno é altamente prevalente, sendo uma preocupação em saúde pública. Objetivo Avaliar a associação entre os tipos de leite ingeridos e o estado nutricional no primeiro ano de vida. Método Estudo longitudinal observacional com crianças brasileiras pertencentes a um estudo multicêntrico. Aos 3, 6, 9 e 12 meses de idade foram investigados os tipos de leite consumidos por meio de questionário de frequência alimentar (QFA) e foi realizada antropometria. As associações brutas e ajustadas foram avaliadas por intermédio de regressão linear. Resultados Das 2.965 duplas de mães-bebês rastreadas, 362 atenderam aos critérios e aceitaram participar do estudo (50% meninos). Aos 12 meses de idade, os maiores escores-z de peso para idade e de peso para comprimento foram observados nos meninos que consumiam apenas fórmula ou apenas leite de vaca. Os maiores escores-z de comprimento para idade foram encontrados entre as meninas que ingeriam apenas fórmula ou apenas leite de vaca aos 9 e 12 meses. Ambos foram comparados àqueles que ingeriam apenas leite materno nas mesmas idades. Conclusão Os tipos de leite consumidos associaram-se ao estado nutricional no primeiro ano de vida, sendo observadas diferenças entre os sexos. Os maiores índices antropométricos nas crianças que não recebiam leite materno chamam a atenção para a persistência futura desses desvios, em direção ao excesso de peso.

Abstract Introduction The World Health Organization (WHO) recommends exclusive breastfeeding up to the 6th month of life of the child and its maintenance with complementary feeding until at least 2 years of age. Despite its importance, the intake of breast milk substitutes is highly prevalent and a public health concern. Objective To evaluate the association between the types of milk ingested and nutritional status in the first year of life. Method Observational longitudinal study with Brazilian children from a multicentric study. At 3, 6, 9, and 12 months of age, the types of milk consumed were investigated using a food frequency questionnaire (FFQ), and anthropometric measurements were performed. Crude and adjusted associations were assessed by linear regression. Results Of the 2,965 pairs of mothers-babies screened, 362 met the criteria and accepted to participate in the study (50% of boys). At 12 months of age, higher weight-for-age and weight-for-length z-scores were observed in boys who consumed only formula or only cow's milk, compared to boys who consumed only breast milk. Higher length-for-age z-scores were found among girls who consumed only formula or only cow's milk at 9 and 12 months, compared to girls who consumed only breast milk at the same ages. Conclusion The types of milk consumed were associated with nutritional status during the first year of life, with differences between boys and girls. The higher anthropometric indexes in children who did not receive breastmilk call our attention to the persistence of such deviations toward excessive weight status in the future.

Diet quality among adolescents in the public education system in a municipality in Southern Brazil: a cross-sectional study, 2019. / Qualidade da dieta de adolescentes da rede pública de ensino de um município do sul do Brasil: estudo transversal, 2019.

OBJECTIVE: To identify the factors associated with the diet quality among 9th grade students in the municipal education system of Pelotas, state of Rio Grande do Sul, Brazil. METHODS: This was a cross-sectional study, conducted in 2019. Food information was collected using a food frequency questionnaire, and diet quality was assessed through an index developed by the authors. Diet was classified as low, intermediate or high quality. The association was assessed using multinomial logistic regression. RESULTS: The 808 adolescents evaluated obtained a mean score of 16.0 points (deviation-standard=4.1) according to the developed index. The high diet quality was associated with tobacco experimentation [odds ratio (OR) 2.92; 95% confidence interval (95%CI) 1.74;4.92] and leisure-time physical activity (OR=1.65; 95%CI 1.15;2.38). CONCLUSION: We highlighted the importance of encouraging physical activity practice, monitoring risk behaviors among adolescents and promoting the consumption of healthy food.

Physical activity and serum interleukin-6 in relation to bone density in young adults / Atividade física e interleucina-6 sérica em relação à densidade óssea em adultos jovens

Physical activity (PA) and inflammation influence bone density through multiple physiological mechanisms, but current evidence is not robust on the structure mediating these relationships. There-fore, the aim of this study was to investigate the associations of PA, and serum interleukin-6 (IL-6) on bone density. Cross-sectional analysis in the Pelotas (Brazil) 1982 Birth Cohort with participants aged 30-years old. PA was objectively measured by accelerometry. Bone mineral density (g/cm2) was evaluated for the lumbar spine and femoral neck using dual-energy X-ray absorptiometry. Crude and adjusted linear regressions and mediation analyses were performed. In both sexes, the overall PA was positively associated with femoral neck bone density, but not lumbar spine. For men, the mean of femoral neck were 0.027, 0.042, and 0.032 higher in the second, third, and fourth quartiles, respectively, compared to the first quartile (reference). Among women, higher bone density values were found in the third (0.021) and fourth (0.027) quartiles of overall PA compared to the lowest quartile. Among females, moderate-to-vigorous intensity physical activity presented a positive rela-tionship with all sites of bone density. The indirect effect through IL-6 was not significant. Physical activity was associated with gains in bone density. The findings reinforce recommendations for PA in adulthood to promote bone health

A atividade física (AF) e a inflamação influenciam a densidade óssea através de múltiplos mecanismos fisiológicos, mas a atual evidência não é robusta sobre a estrutura de mediação dessas relações. Portanto, o objetivo deste estudo foi investigar as associações de AF e interleucina-6 sérica (IL-6) na densidade óssea. Análise transversal na Coorte de Nascimentos de 1982 Pelotas (Brasil) em participantes com 30 anos de idade. AF foi medida objetivamente por acelerometria. Densidade mineral óssea (g/cm2) foi avaliada para a coluna lombar e colo do fêmur usando absorciometria de raios-X de dupla energia. Foram realizadas regressões lineares brutas e ajustadas e análises de mediação. Em ambos os sexos, a AF total foi positivamente associada à densidade óssea do colo do fêmur, mas não à coluna lombar. Para os homens, as médias do colo do fêmur foram 0,027, 0,042 e 0,032 maiores no segundo, terceiro e quarto quartis, respectivamente, em relação ao primeiro quartil (referência). Entre as mulheres, os maiores valores de densidade óssea foram encontrados no terceiro (0,021) e quarto (0,027) quartis de AF total em comparação ao quartil mais baixo. No sexo feminino, a atividade física de intensidade moderada a vigorosa apresentou relação positiva com todos os locais de densidade óssea. O efeito indireto através da IL-6 não foi significativo. A atividade física foi associada a ganhos de densidade óssea. Os achados reforçam recomendações de AF na idade adulta para promover a saúde óssea

Agreement between muscle mass assessments by computed tomography and calf circumference in patients with cancer: A cross-sectional study.

BACKGROUND & AIMS: Cancer influences body composition, including a loss of muscle mass (MM), associated with worse outcomes. The study aimed to evaluate the agreement between MM estimated by calf circumference (CC) and computed tomography (CT) image as a reference method. METHODS: A cross-sectional study including patients (>20 years) diagnosed with cancer attending a reference center of oncology. Spearman's correlation was performed to verify the correlation between CC and MM by CT, including skeletal muscle area - SMA and skeletal muscle index - SMI. ROC curves, Kappa coefficient, sensitivity, specificity, positive and negative predictive values were obtained. RESULTS: The study included 219 patients, age 62.9 ± 13.1 years (mean ± standard deviation). Low CC was observed in 43.8% of the patients, and 29.2% had low SMI. CC positively correlated with SMA (rho = 0.333) and SMI (rho = 0.329), and fair agreements (K = 0.268) were observed between CC and SMI, with higher and significant values for males (K = 0.332) and patients below 60 years (K = 0.419). The area under the curve (AUC) for low CC to identifying low SMI was equal to 0.685 (CI 95% 0.606-0.765). Low CC presented fair agreement to identify low SMI in the sample; however, the negative predictive value was almost 80% for all analyses. CONCLUSIONS: Low CC is not a surrogate for low SMI in patients with cancer, but it could be an alternative, non-invasive, easy-to-perform method to pre-screen patients with cancer with adequate SMI.

NCD behavioral risk factors and mortality among older adults in Brazil.

BACKGROUNDS & AIMS: Literature shows that the most studied concurrent risk factors for mortality in elderly individuals are smoking, inadequate diet, alcohol consumption and physical inactivity. The combination of such habits can increase from 3 to 11 times the chance of death. To measure the association between concurrence of behavioral risk factors (BRF) for non-communicable diseases (NCD's) and mortality up to three years among the elderly. METHODS: Cohort study started in 2014 named "COMO VAI?" with community-dwelling aged ≥60 years in Pelotas, Rio Grande do Sul, Brazil. We investigated the deaths from all causes occurred until April 2017. The exposure was defined by the presence of physical inactivity, low-quality diet, alcohol consumption and smoking that composed a score ranging from 0 (none) to 4 (all). Cox proportional hazard regression models were used to evaluate the association between BRF concurrence and mortality. RESULTS: In 2014, 1451 elderly people were interviewed, 145 deaths were identified (10%) by April 2017. Higher risk of death was observed for the combinations of physical inactivity + smoking and low-quality diet + physical inactivity. The simultaneous presence of three or more BRF was associated with a nearly six-fold higher risk of death. CONCLUSIONS: Higher mortality during a 3-year period was observed among those with at least three BRF for NCD's.

Adequação da frequência e tipos de refeições realizadas por idosos comunitários do sul do Brasil / Adequacy of the frequency and types of meals consumed by community-dwelling elderly folk in the south of Brazil

Resumo O objetivo do estudo foi descrever a frequência e tipos de refeições realizadas por idosos de Pelotas-RS e fatores associados à frequência adequada de refeições. Foi realizado estudo transversal com indivíduos ≥60 anos. Questionou-se sobre as refeições diárias na semana anterior à entrevista. A adequação de refeições foi definida conforme recomendação do Ministério da Saúde (pelo menos três refeições principais e dois lanches por dia). As variáveis independentes foram as características sociodemográficas, de saúde e da rotina alimentar. Razões de prevalência e intervalos de confiança de 95% foram calculados por regressão de Poisson. Dos 1.438 idosos entrevistados, cerca de 40% afirmaram realizar quatro refeições diárias. O almoço foi a refeição mais relatada, seguido do café da manhã. Apresentaram frequên cia adequada de refeições 30,6% dos homens e 38,6% das mulheres (p=0,002). Homens com edentulismo (perda dentária total) tiveram 35% maior probabilidade de adequação, enquanto essa probabilidade foi cerca de 30% menor em mulheres de cor da pele não branca, não escolarizadas e que declararam falta de dinheiro para a compra de alimentos. Um a cada três idosos atendeu a recomendação da frequência adequada de refeições e algumas características sociodemográficas foram negativamente associadas com esse hábito.

Abstract The scope of this study was to describe the frequency and types of meals consumed by the elderly in Pelotas (Brazil) and factors associated with the adequacy of meal frequency. A cross-sectional study was carried out with ≥60 years of age individuals. They were asked about daily meals during the week prior to the interview. The adequacy of meals was defined as recommended by the Ministry of Health (at least three main meals and two small snacks per day). The independent variables were sociodemographic, health and food routine characteristics. Prevalence ratios and 95% confidence intervals were calculated using Poisson regression. Of the 1,438 elderly individuals interviewed, about 40% reported consuming four meals a day. Lunch was the most reported meal, followed by breakfast. A total of 30.6% of men and 38.6% of women had adequate frequency of meals (p=0.002). Men with edentulism (total tooth loss) were 35% more likely to eat adequately, while this probability was about 30% lower among non-white women, those without schooling and those who reported a lack of money to buy food. One in each three elderly people met the recommendation of adequate frequency of meals and some sociodemographic characteristics were negatively associated with this habit.

All-cause mortality over a three-year period among community-dwelling older adults in Southern Brazil.

OBJECTIVE: To evaluate all-cause mortality in approximately three years of follow-up and related sociodemographic, behavioral and health factors in community-dwelling older adults in Pelotas, RS. METHODS: This was a longitudinal observational study that included 1,451 older adults (≥ 60 years) who were interviewed in 2014. Information on mortality was collected from their households in 2016-2017 and confirmed with the Epidemiological Surveillance department of the city and by documents from family members. Associations between mortality and independent variables were assessed by crude and multiple Cox regression, with hazard ratio with respective 95% confidence intervals (95%CI). RESULTS: Almost 10% (n = 145) of the participants died during an average of 2.5 years of follow-up, with a higher frequency of deaths among males (12.9%), ?80 years (25.2%), widowhood (15.0%), no education (13.8%) and who did not work (10.5%). Factors associated with higher mortality were: being a male (HR = 2.8; 95%CI 1.9 - 4.2), age ?80 years (HR = 3.9; 95%CI 2.4 - 6.2), widowhood (HR = 2.2; 95%CI 1.4 - 3.7), physical inactivity (HR = 2.3; 95%CI 1.1 - 4..6), current smoking (HR = 2.1; 95%CI 1.2 - 3.6), hospitalizations in the previous year (HR = 2.0; 95%CI 1.2 - 3.2), depressive symptoms (HR = 2.0; 95%CI 1.2 - 3,4) and dependence for two or more daily life activities (HR = 3.1; 95%CI 1,7 - 5.7). CONCLUSION: The identification of factors that increased the risk of early death makes it possible to improve public policies aimed at controlling the modifiable risk factors that can lead to aging with a better quality of life.
