Socio-economic vulnerability and deaths of despair in Brazilian counties.

Over the past few years, there has been a progressive increase in premature deaths attributable to suicide, drug overdose, and alcohol-related liver disease that impact life expectancy. Regarding the relationship with contextual effects, the evidence is developing, especially in countries with a peripheral economy, as is the case of Brazil. We carried out an analysis aimed at estimating the relationship between socioeconomic insecurity and deaths due to despair in Brazilian cities. We used 5,570 counties' data to create clusters concerning socioeconomic development and then analyzed age-adjusted mortality rates (ASMR) from each of them and compared them using the ANOVA test. Cluster analysis generated two groups of Brazilian municipalities. DoD rates are consistently higher in the group that experiences more deprivation. However, considering differences between 2010 and 2019, the increase in rates was higher in the group with less deprivation experience (48.82 % vs. 39.53 %) We verified an existing gap between the clusters before the beginning of economic stagnation in 2010 The gap between those two groups decreased from 20.58 % (p < 0.001) in 2010 to 14.03 % in 2019 (p = 0.034). The conjuncture of economic crises creates mortality differentials in certain population groups. Also, significant inequalities explain how causes of death from despair affect different subpopulations. Our first approach assessed this assumption, and we could check those differentials at an ecological level. Public policies should focus on reducing the difference in mortality from despair between higher and lower socioeconomic strata.

Cohort study protocol of the Brazilian collaborative research network on COVID-19: strengthening WHO global data.

INTRODUCTION: With the COVID-19 pandemic, hospitals in low-income countries were faced with a triple challenge. First, a large number of patients required hospitalisation because of the infection's more severe symptoms. Second, there was a lack of systematic and broad testing policies for early identification of cases. Third, there were weaknesses in the integration of information systems, which led to the need to search for available information from the hospital information systems. Accordingly, it is also important to state that relevant aspects of COVID-19's natural history had not yet been fully clarified. The aim of this research protocol is to present the strategies of a Brazilian network of hospitals to perform systematised data collection on COVID-19 through the WHO platform. METHODS AND ANALYSIS: This is a multicentre project among Brazilian hospitals to provide data on COVID-19 through the WHO global platform, which integrates patient care information from different countries. From October 2020 to March 2021, a committee worked on defining a flowchart for this platform, specifying the variables of interest, data extraction standardisation and analysis. ETHICS AND DISSEMINATION: This protocol was approved by the Research Ethics Committee (CEP) of the Research Coordinating Center of Brazil (CEP of the Hospital Nossa Senhora da Conceicao), on 29 January 2021, under approval No. 4.515.519 and by the National Research Ethics Commission (CONEP), on 5 February 2021, under approval No. 4.526.456. The project results will be explained in WHO reports and published in international peer-reviewed journals, and summaries will be provided to the funders of the study.

Relationship between body composition and bone mass in normal-weight and overweight adolescents.

Adolescence is a period characterized by large accumulation of bone mass. Body composition is an important determinant of bone mass. This study aimed to assess the relationship of bone mass with lean mass (LM) and fat mass (FM) in normal-weight and overweight adolescents with consideration of sex, sexual maturation and physical activity covariates. A total of 118 adolescents (60 girls and 58 boys) aged between 10 and 14 years participated in the study. Individuals were classified as normal weight or overweight according to body mass index. Bone mineral density (BMD), bone mineral content (BMC), LM, and FM were measured by dual-energy X-ray absorptiometry. In normal-weight adolescents, LM (ß = 0.725, p < 0.001) and FM (ß = 0.185, p = 0.019) were associated with lumbar spine BMC, whereas in overweight adolescents only LM (ß = 0.736, p < 0.001) was associated with lumbar spine BMC. Furthermore, in the normal-weight group, FM and LM were associated with total body less head BMD (LM, ß = 0.792, p < 0.001; FM, ß = 0.257, p = 0.007) and lumbar spine BMD (LM, ß = 0.553, p < 0.001; FM, ß = 0.199, p < 0.035). In the overweight group, only LM was associated with total body less head BMD (ß = 0.682, p < 0.001) and lumbar spine BMD (ß = 0.528, p < 0.001). LM was the main predictor of bone mass in normal-weight and overweight adolescents. FM was associated with bone mass in normal-weight adolescents only. LM may be considered an important and useful marker in adolescents, when investigating bone health in this population. Activities that promote LM gain to reduce the risk of bone fractures and diseases in adulthood are recommended.

Effect of losartan potassium, metformin hydrochloride, and simvastatin on in vitro bioaccessibility of Cu, Fe, Mn, and Zn in oat flour from Brazil.

BACKGROUND: The simultaneous administration of drugs with food can compromise the bioaccessibility and absorption of nutrients. The objective of this study was to evaluate the influence of the use of losartan potassium (LP), metformin hydrochloride (MH), and simvastatin (S) on the in vitro bioaccessibility of micronutrients (Cu, Fe, Mn, and Zn) in oat flour from Bahia, Brazil. METHODS: The experimental procedure consisted of the in vitro extraction of the bioaccessible fraction of Cu, Fe, Mn, and Zn in oat flour-with and without LP (50 mg), MH (500 mg), and S (20 mg)-using the unified bioaccessibility method (UBM), simulating the conditions of the gastrointestinal tract. For decomposition of the samples (oat flour and residue), a digester block with a closed system was used. To determine the total content (flour and residual fraction) and bioaccessible micronutrients, inductively coupled plasma optical emission spectrometry (ICP OES) was used. RESULTS: The bioaccessible contents (µg g-1) without the addition of drugs were: Cu 5.86 ± 0.21, Fe 32.80 ± 1.32, Mn 87.90 ± 1.90, and Zn 30.33 ± 2.05, with bioaccessibility ranging from 31.5 % for Fe to 99 % for Mn. The in vitro extraction method was validated by mass balance with recovery values from 89.78 % for Cu to 101.94 % for Mn. The range of bioaccessible contents (µg g-1) were: Cu (<4.14), Fe (32.10 ± 0.20-54.10 ± 2.03), Mn (81.40 ± 0.93-93.22 ± 0.80), and Zn (<10.80-29.11 ± 2.20). The estimation of the bioaccessibility of Cu, Mn, and Zn in oat flour were compromised in the presence of LP, MH, and S (p < 0.05). CONCLUSION: Chemical interactions can occur between drugs and micronutrients. Taken together, our results highlight that LP, MH, and S can interfere with the bioaccessibility of Cu, Fe, Mn, and Zn in oat flour in patients who use these drugs, suggesting its rational use in further investigations.

The effect of primary health care on tuberculosis in a nationwide cohort of 7·3 million Brazilian people: a quasi-experimental study.

BACKGROUND: Universal health coverage is one of the WHO End TB Strategy priority interventions and could be achieved-particularly in low-income and middle-income countries-through the expansion of primary health care. We evaluated the effects of one of the largest primary health-care programmes in the world, the Brazilian Family Health Strategy (FHS), on tuberculosis morbidity and mortality using a nationwide cohort of 7·3 million individuals over a 10-year study period. METHODS: We analysed individuals who entered the 100 Million Brazilians Cohort during the period Jan 1, 2004, to Dec 31, 2013, and compared residents in municipalities with no FHS coverage with residents in municipalities with full FHS coverage. We used a cohort design with multivariable Poisson regressions, adjusted for all relevant demographic and socioeconomic variables and weighted with inverse probability of treatment weighting, to estimate the effect of FHS on tuberculosis incidence, mortality, cure, and case fatality. We also performed a range of stratifications and sensitivity analyses. FINDINGS: FHS exposure was associated with lower tuberculosis incidence (rate ratio [RR] 0·78, 95% CI 0·72-0·84) and mortality (0·72, 0·55-0·94), and was positively associated with tuberculosis cure rates (1·04, 1·00-1·08). FHS was also associated with a decrease in tuberculosis case-fatality rates, although this was not statistically significant (RR 0·84, 95% CI 0·55-1·30). FHS associations were stronger among the poorest individuals for all the tuberculosis indicators. INTERPRETATION: Community-based primary health care could strongly reduce tuberculosis morbidity and mortality and decrease the unequal distribution of the tuberculosis burden in the most vulnerable populations. During the current marked rise in global poverty due to the COVID-19 pandemic, investments in primary health care could help protect against the expected increases in tuberculosis incidence worldwide and contribute to the attainment of the End TB Strategy goals.

Evaluation of slurry sampling preparation of enteral nutrition formulations for multielement determination using inductively coupled plasma optical emission spectrometry.

An analytical procedure for the multielement determination in enteral nutrition formulations employing slurry sampling and inductively coupled plasma optical emission spectrometry (ICP OES) is proposed. A two-level full-factorial design was applied to assess the influence of the presence of stabilizing agents (HNO3, Triton X-100 and ethanol) on the composition of the slurry. Multiple response was established as a dependent variable. The experimental conditions for the preparation of the slurry were: 2.0 mL of sample and 8.0 mL of 10% (v/v) HNO3. The limits of detection (LOD) were 5; 9; and 10 µg L-1 for Cu, Fe, Zn, respectively. For P, and K, the LOD were 8 and 24 mg L-1, respectively. The method was applied for the analysis of three enteral nutrition formulation samples and the obtained concentrations ranges were (in mg L-1): 0.41-0.43 (Cu), 2.0-2.9 (Fe), 1.7-3.1 (Zn), 682-1409 (K), and 217-344 (P).

Evaluation of multielement/proximate composition and bioactive phenolics contents of unconventional edible plants from Brazil using multivariate analysis techniques.

Unconventional edible plants (UEP) are potential supplementary sources of minerals and bioactive compounds. However, there is still a gap in the literature on UEP composition. In this study, the multielement/proximate composition of ten UEP from Brazil was evaluated by ICP OES. Furthermore, phenolic bioactives were quantified by HPLC-UV-DAD. The UEP showed high moisture content (84.85-95.27%) and elements (in mg Kg-1): Al (122-657), Ca (145-14,229), Cu (8.3-18.81), Fe (177-586), K (12.46-34.50%), Mg (157-1,552), Mn (16.85-84.96), Na (1,107-23,775), P (2,535-6,127), Si (189-1,695), Sr (25.56-104.63) and Zn (0.3-72.31). Nine phenolic bioactive compounds (1-2,147) and three flavonoids (1-2,042 mg Kg-1) were determined. PCA and HCA grouped samples (Java ginseng, Coriander, Spearmint and Indian borage) rich in minerals. Spearmint showed high levels of transcinamic acid, kaempferol and quercetin. This study contributes to the scientific development and use of UEP.

Behavior in children and adolescents associated to screen time in Porto Velho, Brazilian Western Amazon / Comportamento de crianças e adolescentes em relação ao tempo de tela em Porto Velho, Amazônia Ocidental Brasileira

INTRODUCTION: In studies directed to children and adolescents, the sedentary behavior has been usually represented by exposure to screen, which comprise the total or separate measured time exposed to television, videogame, tablets, mobile devices, and computer. OBJECTIVE: To analyze the prevalence and factors associated with screen time in children and adolescents. METHODS: A cross-sectional school-based study was carried out with 1,471 students from Elementary School, aged between 7 to 18 years (51.3% male), enrolled at public schools (55.6%) in Porto Velho, Rondônia (RO) state, Brazil. Excess screen time was defined as watching television, using the computer, and playing video games for more than two hours per day. Poisson regression was used to obtain crude and adjusted prevalence ratios and their respective 95% CI. RESULTS: Overall prevalence of screen time exposure over two hours per day was 65.9%. After adjustments, risk of screen time exposure was higher in males, PR = 1.51 (95% CI: 1.08 - 1.92), under or equal to 14 years old, PR = 1.69 (95% CI: 1.48 - 1.92), in the 5th grade, PR = 1.41 (95% CI: 1.02 - 1.89), in the 6th grade, PR = 1.44 (95% CI: 1.06 - 1.97) and in the 7th grade, PR = 1.52 (95% CI: 1.09 - 2.13), attending two weekly PE classes or fewer, PR = 1.25 (95% CI: 1.07 - 1.53) ), consuming more than 3 daily meals, PR = 2.69 (95% CI: 2.14 - 3.37) and overweight, PR = 1.51 (95% CI: 1.13 - 2.03). CONCLUSION: The findings showed that the exposure equal to or more than two hours of daily screen time was high. The students more exposed to this outcome had the next characteristics: male sex, age less than or equal to 14 years, from the fifth, sixth, and seventh grade of elementary education, practice physical education classes less than or equal to two hours per week, consume more than three meals daily and have excess body fat (G%).

A recomendação é higienização de superfícies e mãos com água, sabão ou higienizadores à base de álcool.(AU)

Objective: to verify the persistence of SARS-CoV-2 on different types of surfaces and the preventive measures against the transmission of the virus. Method: a systematic review was carried out, using the PRISMA method. The PubMed and LILACS databases from January to June 2020 were used, with the following descriptors: "2019-nCOV" OR "SARS-CoV-2" OR "COVID-19" AND "transmission" OR "transmission route" AND "viability" AND "surface" OR "inanimate surface" AND "prevention". Information extracted was author/year, country, type of publication, journal name, language, country of publication and database. Results: 178 publications were identified. 164 articles were excluded, nine by language, 12 by other diseases and/or pathogens and 143 by title and/or abstract. 14 qualitative articles were included, eight articles of narrative reviews, one short communication, two original articles and one editorial. Thirteen articles were published in English and one in Portuguese. Conclusion: human coronaviruses (HCoV 229E) can persist on different surfaces for two hours up to nine days. Low temperatures and low relative humidity of the air favor the survival of SARS-CoV-2, which is more stable on plastics and on stainless steel than on copper and cardboard. The recommendation is frequent surface and hand hygiene with water, soap or alcohol-based rubs.(AU)

Objective: To evaluate the association between physical activity and life-style and presence of chronic noncommunicable diseases (NCDs) in male users of the Basic Health Unit (BHU). Methods: 119 men, aged between 20 and 59 years, participated in the study. The association between the practice of physical activity with sociodemographic variables, alcoholism, smoking, use of medication, presence of chronic noncommunicable diseases and knowledge of men's health policy was carried out by Logistic Regression with an α= 5%. Results: The prevalence of physical activity was 58.8%, however 36.7% of the participants used medica-tions daily and 70.6% did not know the National Policy for Comprehensive Attention to Men's Health. In addition, physical activity proved to be a protective factor against chronic non-communicable diseases (OR= 2,97; IC 95% 1,03 ­ 8,55; p = 0,043). Conclusion: The practice of physical activity in men, regardless of age, smoking and alcohol consumption was associated with the prevention of chronic noncommunicable diseases. (AU)

Influence of Family History of Diabetes on Cardiac Autonomic Dysfunction of Adolescents

Abstract Background To evaluate cardiac autonomic modulation of adolescents with a family history of diabetic parents. Objective This study aims to evaluate the influence of a family history of diabetes on cardiac autonomic modulation. Methods This is an analytical and cross-sectional study on adolescents between 11 and 18 years of age, of both genders, who were divided into group with a family history of diabetes and a control group without a family history of diabetes. The study protocol consisted of the analysis of heart rate variability, blood pressure, anthropometric measurements, and body composition. Also, by using questionnaires, level of physical activity, sexual maturation, and sleep quality were evaluated. Normality of data distribution was tested using the Kolmogorov-Smirnov test. Then, statistical significance was evaluated using the Student's t-test, and the Cohen's teste was used for calculation of the effect size. The level of significance adopted in the statistical analysis was 5%. Results When the group of individuals with a family history of diabetes was compared with the control group, statistically significant differences were observed in the variables the standard deviation of the NN time series interval (SDNN) (43.9 ± 2.2 vs. 53.5 ± 2.6 ms), the square root of the quadratic differences (RMSSD) (41.9 ± 3.3 vs. 52.4 ± 3.2 ms), standard deviation of beat-to-beat instantaneous variability (SD1) (29.7 ± 2.3 vs. 37.1 ± 2.3 ms), long-term standard deviation of continuous RR intervals (SD2) (. 54.1 ± 2.6 vs. 66.66 ± 3.5 ms), and in low frequency (LF) (496.0 ± 49.5 vs. 728 ± 71.6 ms2) and high frequency (HF) (1050.0 ± 120.4 vs. 737.4 ± 98.5 ms2) in the frequency domain. Conclusions Global autonomic modulation is decreased in adolescents with a family history of diabetes. We also observed a decrease in vagal activity in this group. So, sympathetic autonomic modulation is predominant in this population. (Int J Cardiovasc Sci. 2020; [online].ahead print, PP.0-0)

OBJECTIVE: To formulate strategic recommendations to strengthen primary health care (PHC) in Brazil's Unified Health System (SUS) based on expert consultation. METHOD: The present qualitative study, developed from March to August, 2018, included administration of an open questionnaire followed by consensus building among 20 participants representing the five Brazilian regions, selected using the criterion of recognized professional expertise in the field of PHC. Participants answered an online questionnaire created by the authors. The findings were systematized as recommendations, which were submitted for priority ranking by the expert group using a one-round Delphi technique. The final recommendations were discussed in a face-to-face workshop. RESULTS: Of 20 experts, 18 answered the open questionnaire, generating 84 themes for analysis, which were systematized into 44 proposals. Evaluation of these proposals resulted in 20 recommendations, emphasizing expansion of the Family Health Strategy (FHS); enhanced access to PHC; training of professionals for multidisciplinary work in the PHC setting; allocation of technologies to ensure PHC resolvability; improvement of regulation/coordination of services to strengthen a foundational role of PHC in the SUS; human resources, provision of professionals, and support/stimulus for teams; production and dissemination of knowledge; transparency in PHC initiatives; and mediating role of PHC in the healthcare system. CONCLUSIONS: The findings support the FHS as the best model to ensure a strong PHC in the SUS, combined with policies that prioritize essential PHC attributes, especially through innovation in care, management, and communication technologies.

Objetivo: analisar a distribuição espacial da COVID-19 segundo fatores socioeconômicos e demográficos no município de Uberlândia, Minas Gerais. Método: trata-se de um estudo do ecológico, transversal, utilizando dados secundários, de uso e acesso públicos, oriundos do Ministério da Saúde do Brasil, por meio das informações disponíveis no open DataSUS com casos confirmados da COVID-19 e que possuíam, em suas respectivas fichas cadastrais, os bairros de residência. Resultados: a média de idade dos casos confirmados pela COVID-19 foi de 38,83 (±14,29) anos, as faixas etárias mais atingidas foram entre 20 a 29 anos (23,2%), 30 a 39 anos (27,7%), 40 a 49 anos (22,5%), 50 a 59 anos (13,7%) e 70 a 79 anos (5,7%). Todos os setores apresentaram casos da COVID-19, sendo o oeste o mais atingido. Entre os 20 bairros com o maior número de infecção, 11 possuem renda per capita média abaixo de um salário-mínimo, oito bairros com renda per capita média de até dois salários-mínimos e apenas um bairro com renda per capita média acima de dois salários mínimos. Conclusões: o número de casos da COVID-19 foi elevado, espalhando-se rapidamente para todos os setores, afetando, principalmente, bairros de baixa renda per capita. Nos bairros com renda per capita média da população abaixo de um salário-mínimo, concentram-se os piores cenários da COVID-19. A crise global de saúde pública ocasionada pela COVID-19 revelou as desigualdades e as injustiças que ameaçam o bem-estar, a segurança e a vida das pessoas.

Preferências de atividade física em adultos brasileiros: resultados da Pesquisa Nacional de Saúde / Physical activity preferences in Brazilian adults: results from National Health Survey

O objetivo do estudo foi verificar a distribuição dos diferentes tipos de práticas entre os praticantes de atividade física de uma amostra de adultos de acordo com características sociodemográficas. Estudo transversal utilizando dados da Pesquisa Nacional de Saúde (PNS) de 2013, com adultos de 18 anos ou mais, praticantes de atividade física (n = 17.350). As variáveis independentes foram sexo, faixa etária, escolaridade e regiões geográficas. As variáveis dependentes foram os tipos de atividade física mais praticadas na população. Para apresentar as frequências de prática de prática segundo região, escolaridade e idade as atividades as atividades foram divididas em três grupos: caminhada, exercício e esportes. Os dados foram analisados no STATA 12.1. Nos homens, as atividades mais comuns foram futebol (39,1%), caminhada (22,9%) e musculação (15,3%). Nas mulheres, foram a caminhada (48,9%), ginástica (19,2%) e musculação (14,2%). Nos homens, a prática de caminhada foi maior nos mais velhos, sem instrução e da região Centro Oeste (p < 0,001). Quanto a prática de exercícios, nos homens, este hábito foi mais comum entre os mais jovens, com maior escolaridade, e da região Sudeste (p < 0,001). Em relação aos esportes, a prática foi mais comum nos mais jovens, nos com maior escolaridade e da região Norte (p < 0,001), tanto nos homens quanto nas mulheres. A prática esportiva foi menos frequente nas mulheres. Os tipos de atividade têm grande influência da idade, escolaridade dos indivíduos e região do país. Estes aspectos devem ser levados em conta do planejamento de intervenções

This study aims to verify the distribution of different types of practices in Brazilian adults according to sociodemographic variables. Cross-sectional study using data from the National Health Survey (PNS) of 2013 including individuals with 18 years or more practitioners of physical activity (n = 17,350). Independent variables were sex, age, education and geographic regions. The dependent variables were the types of physical activity more frequent in the population. To present frequencies according to region, education and age types of physical activity were classified in three groups: walking, exercise and sports. The data were analyzed in STATA 12.1 using the svy command. Among men, the most common activities were soccer (39.1%), walking (22.9%) and bodybuilding (15.3%). Among women, were walking (48.9%), gymnastics (19.2%) and bodybuilding (14.2%). Among men, walking was higher in older individuals, with no education and in the Midwest region (p < 0.001). For exercise, among men, the habit was more common among younger, with higher education and the Southeast (p < 0.001). Regarding sports, the practice was more common among the younger ones, with higher schooling and the Northern region (p < 0.001). The associations for women were similar to associations for men. The types of physical activity have influence of age, education and region of country. These aspects should be considered in interventions planning. More studies are necessary to under-stand the motivators to choose each practice

Inactive behavior in adolescent students of the brazilian western amazon / Comportamento inativo em estudantes adolescentes da amazônia ocidental brasileira

ABSTRACT Objective: To identify the prevalence of physical inactivity in adolescent students in the city of Porto Velho, RO, Northern Brazil, and its associated factors. Methods: School-based study, conducted with 2,694 adolescents. The self-reported variable for outcome was physical inactivity. Factors associated with inactive behavior were verified by multiple logistic regression. The independent variables were inserted into the model in hierarchical blocks. Results: The overall prevalence of inactive behavior was 39.5%. Females showed a higher prevalence of physical inactivity (46.2%) than males (31.4%). Adolescents in private schools and with reports of negative health perception had a high prevalence of physical inactivity. Regarding associated factors, the female sex showed a magnitude of association of 1.84 with physical inactivity. Being in a private school was associated with a 2.54 times greater chance of physical inactivity compared to public school students. Going to school by bus, car or motorcycle was associated with a 1.29 and 1.63 higher chance of physical inactivity respectively. Adolescents who reported having a negative health perception had 1.29 higher chance of physical inactivity, while having excess body fat showed magnitude of association of 1.36 in adolescents. Conclusions: There was a high prevalence of physical inactivity in the studied adolescents. Considering that the behavior of physical inactivity adopted during adolescence may continue in adulthood, the promotion of actions that can change this behavior may improve health in the future as well as quality of life.

RESUMO Objetivo: Identificar a prevalência do comportamento inativo de estudantes adolescentes da cidade de Porto Velho, RO, Brasil, e os fatores associados a ele. Métodos: Estudo de base escolar realizado com 2.694 adolescentes. A variável autorreferida à exposição ao desfecho foi a inatividade física. Verificam-se os fatores associados ao comportamento inativo pela regressão logística múltipla. As variáveis independentes foram inseridas no modelo em blocos hierarquizados. Resultados: A prevalência geral de comportamento inativo foi de 39,5%. O sexo feminino mostrou maior prevalência de comportamento inativo (46,2%) do que o masculino (31,4%). Adolescentes em escolas particulares e com relatos de percepção de saúde negativa apresentaram alta prevalência de comportamento inativo. Na verificação dos fatores associados, o sexo feminino mostrou magnitude de associação de 1,84 com o comportamento inativo. Estar institucionalizado em escola particular mostrou 2,54 vezes mais chance de ter comportamento inativo em comparação aos estudantes das escolas públicas. A locomoção para escola por ônibus e carro ou motocicleta revelou magnitudes de associação com o comportamento inativo de 1,29 e 1,63, respectivamente. Adolescentes que apontaram a percepção de saúde negativa tiveram 1,29 mais chance de ter comportamento inativo em relação ao relato de saúde positiva, enquanto ter excesso de gordura corporal mostrou magnitude de associação de 1,36 em adolescentes. Conclusões: A prevalência de comportamento inativo foi alta em estudantes adolescentes. Considerando que o comportamento inativo adotado durante a adolescência pode permanecer nos anos posteriores, sugere-se a promoção de ações para a modificação de comportamento visando à melhoria da saúde e qualidade de vida.
