RESUMO
OBJECTIVE: Verify the effect of non-periodized and linear periodized combined training on body image perception and body dissatisfaction in adults with obesity. DESIGN: A randomized clinical trial on the effect of two types of combined training periodization was carried out on people with grade I and II obesity. SETTING: Participants were allocated into three groups: non-periodized periodization group, linear periodization group, and control group, with 23 participants in each. SUBJECTS: Adults with obesity, with a body mass index between 30â kg/m² and 40â kg/m². INTERVENTIONS: The intervention lasted 16 weeks (separated into three mesocycles of 4 weeks and 1 week of familiarization), in 3 weekly sessions of 1 hour each, composed of aerobic (30â min) and muscle strength exercises (six exercises) in the same session. The group with non-periodized model maintained uniform intensity, volume, and workload throughout the mesocycles. The group with the linear periodization model started with low initial intensity, subsequently introducing a gradual increase of intensity in the mesocycles. MAIN MEASURES: Body image perception (current and ideal silhouette) and body dissatisfaction were assessed using the Stunkard silhouette scale. RESULTS: The perception of the current silhouette increased only in the control group (Δ = 1.16; p = 0.04). There was a significant reduction in the ideal silhouette over time (p = 0.001), especially in non-periodized group (Δ = -1.26). Body dissatisfaction increased significantly only over time (p = 0.001), especially for control group (Δ = 1.47). CONCLUSIONS: Regardless of periodization, combined training effectively maintained the perception of the current silhouette and reduced the ideal silhouette in adults with obesity. TRIAL REGISTRATION: Brazilian Registry of Clinical Trials (RBR-3c7rt3).

ABSTRACT: Streb, AR, Passos da Silva, R, Leonel, LdS, Possamai, LT, Gerage, AM, Turnes, T, and Del Duca, GF. Effects of nonperiodized and linear periodized combined training on health-related physical fitness in adults with obesity: a randomized controlled trial. J Strength Cond Res 36(9): 2628-2634, 2022-The aim of this randomized controlled trial study was to compare the effects of 16 weeks of linear periodized and nonperiodized combined training (CT) in cardiorespiratory fitness, muscle strength, and body composition indicators of adults with obesity. Thirty-four obese adults of both sexes (36.6 ± 4.4 years; body mass index, 32.9 ± 2.7 kg·m -2 ) were divided into nonperiodized (NG; n = 8), linear periodized (PG; n = 11), and control (CG; n = 15) groups. The NG and PG groups performed 3 weekly sessions of CT over 16 weeks in different ways. Anthropometric measures, maximal strength for leg press and barbell bench press, maximal oxygen uptake (VÌ o2 max), and ventilatory thresholds were determined before and after intervention. The generalized estimation equation was used, with the applied level of significance for the interaction of 0.10 and the isolated effect of time or group or both of 0.05. Significant and similar increases were observed in the 1-repetition maximum test for bench press (NG: 48.8 ± 5.7 to 55.0 ± 6.1 kg; PG: 48.7 ± 5.7 to 53.8 ± 5.9 kg; p = 0.001) and leg press (NG: 235.2 ± 18.7 to 268.3 ± 19.7 kg; PG: 223.1 ± 25.3 to 253.3 ± 23.1 kg; p = 0.05) in trained groups. Relative VÌ o2 max improved only in PG (27.8 ± 1.3 to 32.0 ± 1.4 mL·kg·min -1 ; p = 0.05), while ventilatory thresholds improved in NG and CG ( p = 0.004 and p = 0.06). There was an increase in body mass in CG (97.6 ± 3.4 to 99.1 ± 2.9 kg) and NG (92.5 ± 5.4 to 93.5 ± 5.4 kg; p = 0.05). Combined training improved maximal upper-body and lower-body strength, regardless of periodization. However, for improvement in VÌ o2 max, linear periodization may be superior to nonperiodization in obese adults.

It is necessary to understand the relationship between different models of exercise periodization and the reduction of cardiovascular risk in adults with obesity. The aim of this study was to verify the effect of two periodization models of combined training on the cardiovascular risk of adults with obesity of both sexes. A randomized clinical trial was conducted with adults of both sexes with obesity. They were divided into three groups: control group (CG), non-periodized combined training group (NG), and combined training group with linear periodization (PG). The NG and PG groups underwent physical exercise training regimen for 16 weeks, in three weekly sessions of 60 min each, with the volume and intensity equalized. Cardiovascular risk was measured by the overall Framingham risk score (FRS). Generalized estimation equations and individual responsiveness analyses were used, stratified by sex. A statistically significant reduction in FRS was observed only in men of the NG (pre: 2.50 ± 0.56; post: 0.50 ± 1.02; p-value = 0.001). There was no statistically significant intervention effect on the women's cardiovascular risk. It was found that, regardless of sex, subjects in the control group mostly presented results of increased cardiovascular risk. In contrast, those belonging to the exercise groups, if not reduced, at least stabilized the chances of suffering a cardiovascular event in the next ten years after 16 weeks of combined training. Sixteen weeks of non-periodized combined training were sufficient to reduce cardiovascular risk in men with obesity. Both periodization models were important to stabilize the risk of developing a cardiovascular disease in the next 10 years.

This paper aims to verify the association between the combined relationship of physical inactivity and sedentary behaviour (SB) at leisure-time and the prevalence of noncommunicable chronic diseases (NCDs) in Brazilian adults and elderly. This is a cross-sectional study, derived from the VIGITEL system, with individuals ≥18 years old (n = 52,675). The presence of NCDs (diabetes, hypertension, and obesity) and the independent variables were defined by self-report. Binary logistic regression was used. While adults with the presence of, at least, one risky behaviour had a higher odds to have obesity (OR active + high SB: 1.25; 95%CI: 1.01;1.54; OR inactive + low SB: 1.47; 95%CI: 1.25;1.73; OR inactive + high SB: 1.77; 95%CI: 1.47;2.12), the elderly had an increased risk for this outcome only when classified as inactive (OR inactive + low SB: 1.43; 95%CI: 1.17;1.75; OR inactive + high SB: 1.87; 95%CI: 1.47;2.38). Inactive adults with low SB were more likely to have diabetes (OR inactive + low SB: 1.31; 95%CI: 1.00;1.71) and hypertension (OR inactive + low SB: 1.26; 95%CI: 1.08;1.46), while physical inactivity was again more strongly associated with these outcomes in the elderly, for diabetes (OR inactive + low SB: 1.23; 95%CI: 1.02;1.48; OR inactive + high SB: 1.75; 95%CI: 1.39;2.19), and hypertension (OR inactive + low SB: 1.22; 95%CI: 1.05;1.41; OR inactive + high SB: 1.60; 95%CI: 1.33;1.94) Both leisure-time behaviours carry a high risk of the prevalence of different NCDs, however, physical inactivity, isolated or combined, showed a greater association with the evaluated outcomes.HighlightsThis cross-national survey included representative sample of people ≥18 years old.Adults with at least one evident risky behavior had a higher chance of obesity.Inactive adults with low sedentary behavior had higher chances for diabetes and hypertension.Physical inactivity was more strongly associated with all diseases in the elderly.

In this study, we evaluated socioeconomic inequalities in the consumption of in natura/minimally processed and ultra-processed foods among adolescents. We used data from the Brazilian National Survey of School Health (PeNSE), 2015. According to the self-reported consumption of beans, vegetables and fruits, a score of in natura/minimally processed foods was generated (0-21 points). Sodas, sweets, instant noodles, and ultra-processed meat were used for the score of ultra-processed foods (0-21 points). Equality indicators were gender, maternal education, and socioeconomic level. Absolute difference, ratios, concentration index and slope index of inequality were calculated. Adolescents (n=101,689, 51% girls, 14.2 years) reported a mean score of 9.97 and 11.46 for ultra-processed foods and in natura/minimally processed foods, respectively. Absolute and relative differences between adolescents with the highest and lowest socioeconomic level, there were differences of 2.64 points and 33% for consumption of in natura/minimally processed foods; and 1.48 points and 15% for ultra-processed foods. Adolescents from higher socioeconomic level ate more in natura/minimally processed foods and ultra-processed foods.

BACKGROUND: The aim was to verify the effect of non-periodized and linear periodized combined (aerobic plus resistance) exercise training on insulin resistance markers in adults with obesity. METHODS: A blinded randomized control trial was conducted with three groups of individuals with obesity (BMI, 30-39.9 kg/m2): control group (CG, n = 23), non-periodized group (NG, n = 23), and linear periodized group (PG, n = 23). The NG and PG performed aerobic and resistance exercises in the same session in aerobic-resistance order for 16 weeks. Both intervention groups trained three sessions weekly, with a total duration of 60 min each. The aerobic training of the NG had a duration of 30 min always between 50% and 59% of the reserve heart rate (HRres), while resistance exercise was comprised of 6 exercises, performed always in 2 × 10-12 maximum repetitions (MRs). The PG progressed the aerobic and resistance training from 40%-49% to 60%-69% (HRres) and from 2 × 12-14 to 2 × 8-10 RM, respectively, along the intervention period. The evaluated indicators of insulin resistance included fasting glucose, fasting insulin, and homeostasis model assessment-estimated insulin resistance (HOMA-IR) collected pre- and post-intervention. The analyses to verify the exercise training effect were performed using generalized estimating equations. RESULTS: After 16 weeks of training, per protocol analysis (n = 39) showed significant reductions in HOMA-IR only in the training groups (NG: Δ = - 1.6, PG: Δ = - 0.6; p = 0.094). Intention-to-treat analysis demonstrated significant reductions in fasting insulin levels (NG: Δ = - 1.4, PG: Δ = - 1.0; p = 0.004) and HOMA-IR (NG: Δ = - 5.5, PG: Δ = - 3.8; p = 0.002). CONCLUSION: Periodized and non-periodized combined exercise training similarly reduces insulin resistance markers in adults with obesity.

RESUMO
OBJECTIVE: To verify the association of obesity with volume, intensity and types of physical activity in leisure time among Brazilian adults and elderly. STUDY DESIGN: Cross-sectional study, with a secondary analysis of data from "Surveillance of Risk Factors and Protection for Chronic Diseases by Telephone Survey". METHODS: The target population comprised adults aged ≥18 years. The outcome was obesity (BMI≥30.0 ââkg/m²) and the exposures were the volume, intensity, and main type of physical activity in leisure time. Binary logistic regression was used and the results were expressed as odds ratio (OR) and 95% confidence intervals (CI95%), with a significance level of 5%. RESULTS: Compared to inactive, the highest volume of leisure time physical activity (≥300min/week) had a lower occurrence of obesity in adults (OR=0.76; CI95%: 0.63, 0.92; p=0.001) and elderly (OR=0.62; CI95%: 0.46, 0.82; p=0.001). In adults, vigorous activities (OR=0.65; CI95%: 0.55, 0.78; p<0.001) and, in the elderly, light/moderate activities (OR=0.75; CI95%: 0.62, 0.89; p<0.001) and vigorous (OR=0.54; CI95%: 0.37, 0.78; p<0.001) presented protective effect for obesity. Among the types of physical activity, running was the most strongly associated with a lower occurrence of obesity in adults (OR=0.54; CI95%: 0.32, 0.92; p=0.024) and elderly (OR=0.27; CI95%: 0.10, 0.69; p=0.006). In adults, strength training (p<0.001), gymnastics (p=0.032) and sports (p=0.013) and in elderly, walking (p=0.001) and sports (p=0.003) also had protective effect. CONCLUSION: A greater volume, vigorous intensity and physical activities of a structuring character and intensity progression, such as running, were associated with the lower occurrence of obesity.

The scope of this paper was to verify the association between the practice of physical activity of different types and the use of insulin in adults and the elderly. This is a cross-sectional population-based study with data from the survey entitled Surveillance of risk factors and protection for chronic diseases by telephone (VIGITEL 2013). The sample consisted of individuals aged ≥18 years, living in the 27 Brazilian capitals and diagnosed with diabetes. The practice of physical activity in commuting, the home, leisure, work and the use of insulin were self-reported. Binary logistic regression was used in crude and adjusted analyses for sociodemographic factors. Of the 4,593 subjects with diabetes, insulin use was reported by 16.2% and 25.5% of adults and the elderly, respectively. The practice of physical activity in the home (OR: 0.61, 95%CI: 0.40; 0.94) and at work (OR: 0.38, 95%CI: 0.18; 0.78) were associated with the lowest use of insulin among the elderly. There was a tendency to reduce insulin use as the number of physically active domains increased among the elderly (p = 0.003). The conclusion drawn was that physical activity practiced alone or in a cumulative way in different domains was associated with lower insulin use among the elderly.
Objetivou-se verificar a associação entre a prática de atividade física em diferentes domínios e o uso de insulina em adultos e idosos. Trata-se de um estudo transversal de base populacional com dados do inquérito Vigilância de fatores de risco e proteção para doenças crônicas por Inquérito Telefônico (VIGITEL 2013). A amostra foi composta por indivíduos com idade ≥18 anos, residentes nas 27 capitais do Brasil e com diagnóstico de diabetes. A prática de atividade física no deslocamento, domicílio, lazer e trabalho, e o uso de insulina foram por autorrelato. Empregou-se regressão logística binária em análises bruta e ajustada para fatores sociodemográficos. Dos 4.593 indivíduos com diabetes, uso de insulina foi relatado por 16,2% e 25,5% dos adultos e idosos, respectivamente. A prática de atividade física no domicílio (RO: 0,61; IC95%: 0,40; 0,94) no trabalho (RO: 0,38; IC95%: 0,18; 0,78) estiveram associadas ao menor uso de insulina em idosos. Houve tendência de redução do uso de insulina à medida que se aumentou a quantidade de domínios fisicamente ativos em idosos (p = 0,003). Conclui-se que, em idosos, a atividade física praticada de forma isolada ou de forma acumulada em diferentes domínios teve associação com o menor uso de insulina.

The scope of this study was to verify the association between risk behaviors and obesity in adults (18 to 59 years of age) in Brazilian capitals. It involved a cross-sectional population-based study conducted by telephone interview. The self-reported variables were obesity, defined by weight and height (BMI ≥ 30 kg/m²) and risk behaviors: physical inactivity (≤ 149 minutes/week), excess sedentarism (≥ 4 hours/day), frequent consumption of sweets (≥ 5 days/week) and meat with fat and/or chicken with skin (≥ 1 day/week). The simultaneity of risk behaviors was analyzed for reasons of observed and expected prevalence. The Poisson and multinomial logistic regressions were used in crude analyses and adjusted for sociodemographic factors. Among the 35,448 adults, the simultaneous consumption of meat with fat, excess sedentarism and physical inactivity (PR: 1.94, 95% CI: 1.45, 2.60), as well as the presence of the four risk behaviors (PR: 1.72, 95% CI: 1.16, 2.53) were associated with obesity in men. In women, the simultaneous consumption of sweets and meat with fat (PR: 1.77, 95% CI: 1.19, 2.66) was also associated with the outcome. In both sexes, there was an increase in the tendency of obesity according to the sum total of risk behaviors.
Objetivou-se verificar a associação da simultaneidade de comportamentos de risco com a obesidade em adultos (18 a 59 anos) das capitais do Brasil. Trata-se de um estudo transversal de base populacional, realizado por entrevista telefônica. As variáveis autorrelatadas foram a obesidade, definida pelo peso e altura (IMC ≥ 30 kg/m²) e os comportamentos de risco: inatividade física (≤ 149 min/sem), tempo sentado em excesso (≥ 4h/dia), consumo frequente de doces (≥ 5 dias/sem) e de carnes vermelhas com gordura e/ou frango com pele (≥ 1 dia/sem). A simultaneidade dos comportamentos de risco foi analisada por razões das prevalências observadas e esperadas. Foram utilizadas as regressões de Poisson e logística multinomial, em análises por sexo, brutas e ajustadas por fatores sociodemográficos. Dentre os 35.448 adultos, nos homens, a simultaneidade do consumo de carnes com gordura, tempo sentado em excesso e inatividade física (RP: 1,94; IC95%: 1,45; 2,60), assim como a presença dos quatro comportamentos de risco (RP: 1,72; IC95%: 1,16; 2,53), associaram-se à obesidade. Em mulheres, o consumo simultâneo de doces e de carnes com gordura (RP: 1,77; IC95%: 1,19; 2,66) também se associou ao desfecho. Em ambos os sexos, observou-se aumento da tendência de obesidade conforme o somatório de comportamentos de risco.

In obese populations, the exacerbated increase in adipose tissue results in a significant reduction of health-related physical fitness and can affect the phase angle (PhA), a promising health indicator of cell health and integrity. The aim of this study was to investigate the association of PhA with health-related physical fitness indicators in obese adults. This cross-sectional study had a non-probabilistic sample and was conducted from April to June 2018. The PhA was obtained by a bioelectrical impedance analysis, and the health-related physical fitness indicators evaluated were percentage of body fat (%BF), lower- and upper-body maximal strength, cardiorespiratory fitness (relative VÌO2peak), and flexibility. Pearson and Spearman´s linear correlations, crude and adjusted linear regression analyses were performed. A total of 69 obese adults (60.8% female; BMI = 33.5 ± 2.8 kg/m2) with a mean age of 34.6 ± 7.1 years were studied. The PhA means were 5.8 (±0.6º) and had an inverse correlation with %BF (r=-0.74; p<0.001) and positive correlation with VÌO2peak (r=0.50; p<0.001), lower- and upper-body maximal strength (r=0.65; r=0.70; p<0.001, respectively). After adjustment, %BF (ß=-0.065, adjusted R2=0.53; p<0.001), lower- and upper-body maximal strength (ß=0.004; adjusted R2=0.46; p<0.001, and ß=0.024; adjusted R2=0.50; p<0.001, respectively) were predictors of PhA. Our results suggest the favorable role of PhA as a clinically viable tool to screen and identify the physical fitness variables and functional status of obese adults.

The literature discusses that combined training, aerobic more resistance exercises in the same session, is a suitable strategy for people with obesity and that exercise periodization leads to positive health outcomes; however, the implication of different periodizations of combined training for health outcomes in obese adults requires further investigation. The aim of the study will be to describe the methodology used to compare the effect of linear periodized and non-periodized combined training on health markers and health-related physical fitness in adults with obesity. This is a blinded randomized controlled clinical trial investigating adults with obesity in the age group 20-50 years. The sample will be non-probabilistic, and participants will be allocated randomly into one of three groups: control group (CG), non-periodized group (NG), and periodized group (PG). The intervention will occur in 60-min sessions, 3 days a week for 16 weeks, with 1 week dedicated to familiarization with the training and 15 weeks of combined training (aerobic followed by resistance in the same session). The PG group will perform three mesocycles of 5 weeks each, progressing in intensity throughout the intervention [aerobic: from 40-49% to 60-69% of heart rate reserve (HRR); strength: from 12 to 14 maximum repetitions (MR) to 8 to 10MR]; the NG group will maintain the same relative intensity throughout the study (aerobic: 50-59% of HRR; strength: 2 sets of 10-12 MR). Participants in the CG group will maintain their usual activities without the proposed intervention. Pre- and post-intervention assessments will be performed for biochemical markers, body composition, cardiovascular parameters, cardiorespiratory fitness, maximum upper and lower limb strength, flexibility, and subjective health-related parameters. This project was approved by the Committee of Ethics and Research with Human Beings of the institution of origin (protocol 2,448,674) and registered in the Brazilian Registry of Clinical Trials (RBR-3c7rt3).
RESUMO
ABSTRACT Objective To verify the factors associated with the perception of current silhouette and body image dissatisfaction in adults with obesity. Methods Cross-sectional study derived from the baseline of a randomized clinical trial. The perception of current silhouette and dissatisfaction with body image, defined by the difference between the perception of current and ideal silhouette, were obtained from a scale that ranged from one (smallest silhouette) to nine (largest silhouette). The independent variables investigated as associated factors (crude and adjusted linear regression) were: sex, age, skin color, body mass index (kg/m2), percentage of body fat, level of physical activity, and food intake. Results Sixty-nine obese individuals (body mass index ≥30kg/m2) were studied, 42 of whom were female and with the following mean values: 34.7 (±7.2) years; 33.5 (±2.8) kg/m2, and current silhouette of 6.6 (±0.9). All were dissatisfied with their excess body weight. The categories associated with a perception that matched the current silhouettes were male sex, white skin color, and higher body mass index values when compared to female sex, non-white, and lower body mass index values, respectively. Regarding body image dissatisfaction, white people had lower scores than those with other skin colors. Conclusion Being male, having white skin color, and having a higher body mass index were risk factors for the perception of larger body silhouettes, while only non-white skin color was associated with dissatisfaction with body image.
RESUMO Objetivo Verificar os fatores associados à percepção da silhueta atual e à insatisfação com a imagem corporal em adultos com obesidade. Métodos Estudo transversal derivado da linha de base de um ensaio clínico randomizado. A percepção de silhueta atual e a insatisfação com a imagem corporal, definida pela diferença entre a percepção da silhueta atual e da ideal, foram obtidas a partir de uma escala variando de um (menor silhueta) a nove pontos (maior silhueta). As variáveis independentes investigadas como fatores associados (regressão linear bruta e ajustada) foram: sexo, idade, cor da pele, índice de massa corporal (kg/m2), percentual de gordura corporal, nível de atividade física e ingestão alimentar. Resultados Foram investigados 69 obesos (índice de massa corporal ≥30kg/m2), sendo 42 do sexo feminino e com os seguintes valores médios: 34,7 (±7,2) anos; 33,5 (±2,8) kg/m2 e silhueta atual de 6,6 (±0,9). Todos estavam insatisfeitos pelo excesso de peso corporal. As categorias que se associaram à percepção da silhueta atual foram o sexo masculino, a cor de pele branca e maiores valores de índice de massa corporal quando comparados os dados referentes ao sexo feminino, a pessoas de cor da pele não branca e a menores valores de índice de massa corporal, respectivamente. Quanto à insatisfação com a imagem corporal, pessoas consideradas brancas tiveram escores mais baixos que aquelas com outras cores de pele. Conclusão Ser do sexo masculino, ter cor da pele branca e ter maior índice de massa corporal foram fatores de risco para a percepção de silhuetas corporais maiores, enquanto apenas a cor da pele não branca esteve associada à insatisfação com a imagem corporal.

O estudo teve como objetivo determinar os motivos de adesão, aderência e desistência de adultos com obesidade em um programa de intervenção de exercícios físicos. Trata-se de uma estudo descritivo com 69 adultos com obesidade, os quais estiveram envolvidos em um ensaio clínico controlado. Nos grupos de exercícios físicos, as sessões continham treinamento aeróbio e de força, totalizando 60 minutos, durante 16 semanas. Os motivos de adesão, aderência e desistência foram determinados por questionário e uma análise descritiva (quanti-qualitativa) foi realizada, de acordo com a frequência em que os motivos foram relatados pelos participantes. Verificou-se baixa aderência ao treinamento, bem como altos índices de desistência. A saúde, a qualidade de vida e a estética foram os principais motivos de adesão. Para a aderência, os aspectos mais prevalentes foram a saúde, o comprometimento e à motivação. Contudo, para a desistência, trabalho e a desmotivação foram mais relatados. É importante a intervenção profissional no campo da atividade física e saúde considere estes diferentes motivos e as mudanças neles durante o processo e direcione ações a fim de aumentar a adesão e a aderência e reduzir as desistências
The study aimed to determine the reasons for adherence, adherence and dropout of adults with obesity in a physical exercise intervention program. This is a descriptive study with 69 adults with obesity, who were involved in a controlled clinical trial. In the physical exercise groups, the sessions contained aerobic and strength training, totaling 60 minutes, during 16 weeks. The reasons for adhesion, adherence and dropout were determined by questionnaire and a descriptive analysis (quantitative and qualitative) was carried out, according to the frequency with which the reasons were reported by the participants. There was low adher-ence to training, as well as high dropout rates. Health, quality of life and aesthetics were the main reasons for adhesion. For adherence, the most prevalent aspects were health, commitment and motivation. However, for dropout, work and lack of motivation were more reported. It is important for professional intervention in the field of physical activity and health to consider these different reasons and the changes in them during the process and direct actions in order to increase adhesion and adherence and reduce dropouts

ABSTRACT Multiprofessional residencies in the professional health field (MHR) are intersectoral cooperation programs to qualify health professionals. This study aimed to characterize the offer of vacancies meant for the professional Physical Education field in Brazilian MHR programs. It is a descriptive study of a documentary nature on the offer of training vacancies in MHR for the professional Physical Education field in 2022. The characterization of the programs considered: federative unit, proposing institution, total number of general vacancies, vacancies offered for Physical Education, focus of intervention of the programs, and other professional fields presented in the identified programs. A total of 184 vacancies offered by 77 MHR programs that include Physical Education in Brazil were identified. The Northeast region had the highest number of programs (n=29) and vacancies offered (n=89). Family Health was the major focus as to vacancies, while nursing appeared as the most frequent professional field among the identified programs (97.4%). This research work presented the characterization of the offer of vacancies intended for Physical Education in Brazilian MHR programs. Additionally, it evidences the need for a more equitable distribution of vacancies for Physical Education in the country.

Abstract In this study, we evaluated socioeconomic inequalities in the consumption of in natura/minimally processed and ultra-processed foods among adolescents. We used data from the Brazilian National Survey of School Health (PeNSE), 2015. According to the self-reported consumption of beans, vegetables and fruits, a score of in natura/minimally processed foods was generated (0-21 points). Sodas, sweets, instant noodles, and ultra-processed meat were used for the score of ultra-processed foods (0-21 points). Equality indicators were gender, maternal education, and socioeconomic level. Absolute difference, ratios, concentration index and slope index of inequality were calculated. Adolescents (n=101,689, 51% girls, 14.2 years) reported a mean score of 9.97 and 11.46 for ultra-processed foods and in natura/minimally processed foods, respectively. Absolute and relative differences between adolescents with the highest and lowest socioeconomic level, there were differences of 2.64 points and 33% for consumption of in natura/minimally processed foods; and 1.48 points and 15% for ultra-processed foods. Adolescents from higher socioeconomic level ate more in natura/minimally processed foods and ultra-processed foods.
Resumo Nesse estudo, avaliamos as desigualdades socioeconômicas no consumo de alimentos in natura/minimamente processados e ultraprocessados entre adolescentes. Foram utilizados dados da Pesquisa Nacional de Saúde do Escolar (PeNSE), 2015. De acordo com o consumo autorrelatado de feijão, hortaliças e frutas, foi gerado um escore de alimentos in natura/minimamente processados (0-21 pontos). Refrigerantes, doces, macarrão instantâneo e carnes ultraprocessadas prontos para o consumo foram utilizados para a pontuação dos alimentos ultraprocessados (0-21 pontos). Os indicadores de equidade foram gênero, educação materna e nível socioeconômico. Foram calculados a diferença absoluta, razões, índice de concentração e índice de inclinação de desigualdade. Os adolescentes (n=101.689, 51% meninas, 14,2 anos) relataram escore médio de 9,97 e 11,46 para alimentos ultraprocessados e in natura/minimamente processados, respectivamente. As diferenças absolutas entre os adolescentes de alto e baixo nível socioeconômico foram mais altos e mais baixos, houve diferenças de 2,64 pontos e 33% para o consumo de alimentos in natura/minimamente processados; e 1,48 pontos e 15% para alimentos ultraprocessados. Adolescentes de níveis socioeconômicos mais elevados comeram mais alimentos in natura/minimamente processados e alimentos ultraprocessados comparado aos seus pares.
RESUMO
The aim of this study was to identify barriers to use Outdoor Gyms (OGs) for physical activity (PA) practice and to examine their association with leisure-time PA, demographic and socioeconomic var-iables in adults and elderly. This cross-sectional population-based study enrolled 431 adults and elderly (66.8% women) aged 18 to 87 years living in the surroundings (up to 500 meters) of four OGs. Information about using OGs for PA practice, barriers to use OGs, leisure-time PA, demographic and socioeconomic variables were collected by domiciliary interview. Associations between barriers to use OGs with other included variables were analyzed using Chi-Square test. None barriers was re-ported for 29.2% (95%CI: 24.9-33.5) of the participants, being almost of then OGs' users. The most reported barriers to use OGs were lack of time (21.6%; 95%CI: 17.7-25.5), lack of interest (16.5%; 95%CI: 13.0-20.0) and laziness (10.7%; 95%CI: 7.8-13.6). Intrapersonal barriers were more often among men, interpersonal among women and environmental among those with less educational level (p < 0.05). In conclusion, OGs' users perceived fewer barriers than non-users, and most barriers to the use of OGs were intrapersonal with lack of time being the most prevalent
O objetivo deste estudo foi identificar as barreiras para o uso de Academias ao Ar Livre (AAL) para a prática de Atividade Física (AF) e examinar sua associação com a AF no lazer, variáveis demográficas e socioeconômicas em adultos e idosos. Este estudo transversal de base populacional incluiu 431 adultos e idosos (66,8% mulheres) com idades entre 18 e 87 anos moradores do entorno (até 500 metros) de quatro AAL. Informações sobre o uso da AAL para prática de AF, barreiras para o uso de AAL, AF de lazer, variáveis demográficas e socioeconômicas foram coletadas por entrevista domiciliar. As associações entre barreiras para o uso de AAL com as demais variáveis foram analisadas pelo teste do Qui-quadrado. Não perceber barreiras foi relatada por 29,2% (IC95%: 24,9-33,5) dos participantes, sendo praticamente todos os usuários de AAL. As barreiras mais relatadas para o uso de AAL foram falta de tempo (21,6%; IC95%: 17,7-25,5), falta de interesse (16,5%; IC95%: 13,0-20,0) e preguiça (10,7%; IC95%: 7,8-13,6). As barreiras intrapessoais foram mais frequentes entre os homens, as interpessoais entre as mulheres e as ambientais entre aqueles com menor nível educacional (p <0,05). Em conclusão, os usuários de AAL perceberam menos barreiras do que os não usuários, e a maioria das barreiras para o uso de AAL é intrapessoal, sendo a falta de tempo a mais prevalente

Resumo Objetivou-se verificar a associação entre a prática de atividade física em diferentes domínios e o uso de insulina em adultos e idosos. Trata-se de um estudo transversal de base populacional com dados do inquérito Vigilância de fatores de risco e proteção para doenças crônicas por Inquérito Telefônico (VIGITEL 2013). A amostra foi composta por indivíduos com idade ≥18 anos, residentes nas 27 capitais do Brasil e com diagnóstico de diabetes. A prática de atividade física no deslocamento, domicílio, lazer e trabalho, e o uso de insulina foram por autorrelato. Empregou-se regressão logística binária em análises bruta e ajustada para fatores sociodemográficos. Dos 4.593 indivíduos com diabetes, uso de insulina foi relatado por 16,2% e 25,5% dos adultos e idosos, respectivamente. A prática de atividade física no domicílio (RO: 0,61; IC95%: 0,40; 0,94) no trabalho (RO: 0,38; IC95%: 0,18; 0,78) estiveram associadas ao menor uso de insulina em idosos. Houve tendência de redução do uso de insulina à medida que se aumentou a quantidade de domínios fisicamente ativos em idosos (p = 0,003). Conclui-se que, em idosos, a atividade física praticada de forma isolada ou de forma acumulada em diferentes domínios teve associação com o menor uso de insulina.
Abstract The scope of this paper was to verify the association between the practice of physical activity of different types and the use of insulin in adults and the elderly. This is a cross-sectional population-based study with data from the survey entitled Surveillance of risk factors and protection for chronic diseases by telephone (VIGITEL 2013). The sample consisted of individuals aged ≥18 years, living in the 27 Brazilian capitals and diagnosed with diabetes. The practice of physical activity in commuting, the home, leisure, work and the use of insulin were self-reported. Binary logistic regression was used in crude and adjusted analyses for sociodemographic factors. Of the 4,593 subjects with diabetes, insulin use was reported by 16.2% and 25.5% of adults and the elderly, respectively. The practice of physical activity in the home (OR: 0.61, 95%CI: 0.40; 0.94) and at work (OR: 0.38, 95%CI: 0.18; 0.78) were associated with the lowest use of insulin among the elderly. There was a tendency to reduce insulin use as the number of physically active domains increased among the elderly (p = 0.003). The conclusion drawn was that physical activity practiced alone or in a cumulative way in different domains was associated with lower insulin use among the elderly.

Resumo Objetivou-se verificar a associação da simultaneidade de comportamentos de risco com a obesidade em adultos (18 a 59 anos) das capitais do Brasil. Trata-se de um estudo transversal de base populacional, realizado por entrevista telefônica. As variáveis autorrelatadas foram a obesidade, definida pelo peso e altura (IMC ≥ 30 kg/m²) e os comportamentos de risco: inatividade física (≤ 149 min/sem), tempo sentado em excesso (≥ 4h/dia), consumo frequente de doces (≥ 5 dias/sem) e de carnes vermelhas com gordura e/ou frango com pele (≥ 1 dia/sem). A simultaneidade dos comportamentos de risco foi analisada por razões das prevalências observadas e esperadas. Foram utilizadas as regressões de Poisson e logística multinomial, em análises por sexo, brutas e ajustadas por fatores sociodemográficos. Dentre os 35.448 adultos, nos homens, a simultaneidade do consumo de carnes com gordura, tempo sentado em excesso e inatividade física (RP: 1,94; IC95%: 1,45; 2,60), assim como a presença dos quatro comportamentos de risco (RP: 1,72; IC95%: 1,16; 2,53), associaram-se à obesidade. Em mulheres, o consumo simultâneo de doces e de carnes com gordura (RP: 1,77; IC95%: 1,19; 2,66) também se associou ao desfecho. Em ambos os sexos, observou-se aumento da tendência de obesidade conforme o somatório de comportamentos de risco.
Abstract The scope of this study was to verify the association between risk behaviors and obesity in adults (18 to 59 years of age) in Brazilian capitals. It involved a cross-sectional population-based study conducted by telephone interview. The self-reported variables were obesity, defined by weight and height (BMI ≥ 30 kg/m²) and risk behaviors: physical inactivity (≤ 149 minutes/week), excess sedentarism (≥ 4 hours/day), frequent consumption of sweets (≥ 5 days/week) and meat with fat and/or chicken with skin (≥ 1 day/week). The simultaneity of risk behaviors was analyzed for reasons of observed and expected prevalence. The Poisson and multinomial logistic regressions were used in crude analyses and adjusted for sociodemographic factors. Among the 35,448 adults, the simultaneous consumption of meat with fat, excess sedentarism and physical inactivity (PR: 1.94, 95% CI: 1.45, 2.60), as well as the presence of the four risk behaviors (PR: 1.72, 95% CI: 1.16, 2.53) were associated with obesity in men. In women, the simultaneous consumption of sweets and meat with fat (PR: 1.77, 95% CI: 1.19, 2.66) was also associated with the outcome. In both sexes, there was an increase in the tendency of obesity according to the sum total of risk behaviors.

It is well known that some unhealthy behaviors are potentially associated with hypertension, but it is not known which combinations of simultaneous behaviors increase the chance of developing hypertension. In addition, more evidence is needed to assist in the development of preventive public policies in low- and middle-income countries. Thus, the objective was to determine the association between the clustering of four unhealthy behaviors and the occurrence of hypertension among Brazilian adults. The secondary data analyzed are derived from VIGITEL 2015 database, a cross-sectional national surveillance that included 35,548 adults aged 18 to 59 years living in Brazilian state capitals. Unhealthy behaviors and hypertension were measured by self-report. Sixteen combinations based on the presence and absence of the four unhealthy behaviors were performed and binary logistic regression was used to determine the association between simultaneity of these behaviors and hypertension. The odds to have all unhealthy behaviors were 3.50 (95%CI: 2.96 - 4.10) times higher than the expected value if unhealthy behaviors were independent. Adults with simultaneous all risk behaviors (OR = 2.42; 95%CI: 1.20 - 4.85), with excessive salt consumption and physical inactivity (OR = 1.41; 95%CI: 1.11 - 1.80) and with excessive alcohol consumption and physical inactivity (OR =1.60; 95%CI: 1.14 - 2.25) were more likely to have hypertension compared to the people without unhealthy behaviors. In conclusion, some combinations of unhealthy behaviors were actually more dangerous for hypertension in the investigated population. Future public policies to prevent hypertension can be more effective if to focus on simultaneity of unhealthy behaviors that increased the chance of developing the disease, especially physical inactivity.
A associação existente entre alguns comportamentos não saudáveis e hipertensão está bem estabelecida na literatura, entretanto, ainda não está claro quais agrupamentos em específico podem aumentar a chance de desenvolvimento da doença. Ademais, são necessárias mais evidências para auxiliar no desenvolvimento de políticas públicas preventivas em países de baixa e média renda. Assim, o objetivo do presente estudo foi investigar a associação entre os agrupamentos de quatro comportamentos não saudáveis e hipertensão em adultos brasileiros. Os dados analisados são derivados do banco de dados Vigitel 2015, uma pesquisa transversal que incluiu 35.548 adultos entre 18 e 59 anos residentes em capitais brasileiras. Os comportamentos não saudáveis e hipertensão foram medidos por meio de auto relato. Dezesseis combinações baseadas na presença e ausência dos quatro comportamentos foram realizadas e para determinar a associação entre a simultaneidade desses comportamentos e hipertensão foi utilizada regressão logística binária. A chance de ter todos os comportamentos não saudáveis foi 3,50 (IC95%: 2,96 - 4,10) vezes maior que o esperado se os comportamentos fossem independentes. Adultos com todos os comportamentos não saudáveis (OR = 2,42; IC95%: 1,20 - 4,85), com consumo excessivo de sal e inatividade física (OR = 1,41; IC95%: 1,11 - 1,80) e com consumo excessivo de álcool e inatividade física (OR = 1,60; IC95%: 1,14 - 2,25) apresentaram associação com hipertensão. Conclui-se que algumas combinações de comportamentos não saudáveis foram mais perigosas para o desenvolvimento da hipertensão na população investigada. Futuras políticas públicas focadas na prevenção dessa doença podem ser mais eficazes se considerarem os agrupamentos que aumentam a chance de desenvolver a hipertensão, principalmente a inatividade física.

ABSTRACT Objective To investigate the association between different domains (leisure, work, commuting, and household) of physical activity, independent and cumulative, and excess weight and obesity in Brazilian adults. Methods This is a cross-sectional survey, conducted in 2015, through telephone interviews with a representative sample of adults from the capitals of Brazil. Physical inactivity was defined as non-participation in predefined physical activities for each assessed domain. Excess weight (Body Mass Index?25kg/m2) and obesity (Body Mass Index?30kg/m2) were determined from self-reported measurements of weight and height. A binary logistic regression was conducted after adjusting for sociodemographic factors. Results Among 54,174 subjects, physical inactivity in commuting (ORexcess weight=1.27, 95%CI=1.13,1.42 and ORobesity=1.25, 95%CI=1.06,1.47) and leisure (ORexcess weight=1.12, 95%CI=1.04,1.22 and ORobesity=1.30, 95%CI=1.17,1.45) domains were associated with nutritional status. In addition, a linear trend was observed between increasing obesity and cumulative physical inactivity of all four domains (p<0.001). Conclusion Cumulative physical inactivity, especially in the commuting and leisure domains, was associated with excess weight and obesity in adults living in the capitals of Brazil. One possible explanation of these findings is that these domains involve particularly longer duration and greater intensity of physical inactivity. Public policies concerning physical activity should prioritize actions focused in promoting physical activity on commuting and leisure-time to help prevent overweight and obesity in the Brazilian adult population.
RESUMO Objetivo Investigar a associação entre a atividade física em diferentes domínios (deslocamento, domicílio, lazer e trabalho) isolados e acumulados com a ocorrência de excesso de peso e obesidade em adultos brasileiros. Métodos Trata-se de um inquérito transversal, realizado em 2015, por meio de entrevista telefônica com uma amostra representativa de adultos das capitais do Brasil. A inatividade física foi determinada como a não participação em atividades físicas específicas para cada domínio avaliado. O excesso de peso (Índice de Massa Corporal?25kg/m2) e a obesidade (Índice de Massa Corporal ?30kg/m2) foram definidos pelo autorrelato de peso e altura. Na esta-tística, empregou-se a regressão logística binária ajustada para fatores sociodemográficos. Resultados Dentre os 54.174 sujeitos, observou-se que a inatividade física no deslocamento (OR=1,27; IC95%:1,13;1,42 e OR=1,25; IC95%:1,06;1,47) e no lazer (OR=1,12; IC95%:1,04;1,22 e OR=1,30; IC95%:1,17;1,45) estiveram associadas ao excesso de peso e à obesidade, respectivamente. Observou-se ainda uma tendência linear de aumento da obesidade à medida que se acumulam domínios com inatividade física (p<0,001). Conclusão A inatividade física acumulada em diferentes domínios, particularmente no deslocamento e no lazer, apresentou associação com o excesso de peso e obesidade em adultos residentes nas capitais do Brasil. Possivelmente, importantes características da atividade física nos referidos domínios, como a maior duração e a maior intensidade, sejam potenciais justificativas para o encontro de tais achados. Portanto, recomenda-se que políticas públicas de atividade física possam priorizar ações voltadas para os domínios do deslocamento e do lazer no combate ao excesso de peso e obesidade na população adulta brasileira.
