Effect of Combined Physical Exercise Training in Reducing Cardiovascular Risk Among Adults with Obesity: A Randomized Clinical Trial.

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.

Noncommunicable chronic diseases clusters in Brazilian adults and older adults: correlations as multimorbidity / Agrupamento de doenças crônicas não transmissíveis em adultos e idosos brasileiros: correlações como multimorbidade

Abstract Background Health has dynamic conditions and overlapping pathophysiological factors. For health prevention and promotion, actions are necessary to understand the most common risk combinations. Objective Describe noncommunicable chronic diseases (NCDs) clusters and investigate specific multimorbidity combinations in Brazilian adults and older adults. Method This study used data from Vigitel 2013 survey held in the Brazilian capitals (52,929 interviews). A self-report of diabetes, dyslipidemia, hypertension, and obesity was used. The analyses were the descriptive cluster of NCDs and an adjusted binary logistic regression (odds ratio [OR]), stratified by age. Results Among adults, the clusters of diabetes, dyslipidemia, hypertension, and obesity (O/E = 18.74) and diabetes, hypertension, and obesity (O/E = 16.83) were higher. There was a higher clustering between diabetes and obesity (O/E = 7.25). Among adults, diabetes was associated with dyslipidemia (OR: 3.04), hypertension (OR: 3.84), and hypertension with obesity (OR: 3.34). In older adults, hypertension was associated with diabetes (OR: 2.79), dyslipidemia (OR: 2.06), and obesity (OR: 2.26). Conclusion Other diseases combined with diabetes and hypertension were more frequent in adults and older adults. It is suggested to combine preventive and control measures for these diseases for the non-occurrence of new diagnoses.

Resumo Introdução A saúde apresenta condições dinâmicas e fatores fisiopatológicos sobrepostos. Para ações de prevenção e promoção da saúde é necessário entender as combinações comuns de risco. Objetivo Descrever os agrupamentos de doenças crônicas não transmissíveis (DCNT) e investigar combinações específicas de multimorbidade em adultos e idosos no Brasil. Método Este estudo utilizou dados da pesquisa Vigitel 2013, realizada nas capitais brasileiras (total de 52.929 entrevistas). Foi utilizado um relato de diabetes, dislipidemia, hipertensão e obesidade. Nas análises foram utilizados o agrupamento descritivo de DCNT e uma regressão logística binária ajustada (razão de odds [RO]), estratificada por idade. Resultados Entre os adultos, os grupos de diabetes, dislipidemia, hipertensão e obesidade (O / E = 18,74), bem como diabetes, hipertensão e obesidade (O / E = 16,83) foram maiores. Nos idosos, houve maior agrupamento entre diabetes e obesidade (O / E = 7,25). Entre os adultos, o diabetes foi associado à dislipidemia (RO: 3,04) e hipertensão (RO: 3,84), enquanto a hipertensão à obesidade (RO: 3,34). Nos idosos, a hipertensão foi associada a diabetes (RO: 2,79), dislipidemia (RO: 2,06) e obesidade (RO: 2,26). Conclusão Os agrupamentos de outras doenças combinadas com diabetes e hipertensão foram mais frequentes em adultos e idosos. Sugere-se que além das medidas existentes de prevenção para essas doenças também sejam propostas medidas de controle para a não ocorrência de novos diagnósticos.

Socioeconomic inequalities in the consumption of minimally processed and ultra-processed foods in Brazilian adolescents.

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.

Motivos de adesão, aderência e desistência de adultos com obesidade em um programa de exercícios físicos / Reasons for adhesion, adherence and dropout of obese adults in a exercise program

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

Quality of life and its relationship with different anthropometric indicators in adults with obesity / Qualidade de vida e sua relação com diferentes indicadores antropométricos em adultos com obesidade

Abtract Introduction: Obesity compromises the quality of life. However, few studies have investigated the influence of different anthropometric indicators on the quality of life of this population. Objective: We aimed to correlate the physical and mental components of quality of life and verify its association with different anthropometric indicators in adults with obesity. Methods: A cross-sectional study was conducted in adults with obesity [body mass index (BMI) ≥ 30 kg/m²]. The quality of life was investigated using the SF-36 questionnaire, with scores ranging from 0 (worst-case scenario) to 100 (best scenario for the outcome). The anthropometric indicators used were BMI, waist circumference, waist/height ratio (WHR), and lean and fat body mass. For analysis, Spearman's correlation and crude and adjusted linear regression for sociodemographic variables were used. Results: A total of 75 subjects (nfemales = 47; µage= 34.8 ± 7.1 years) were included, and their means of the physical and mental components were 64.5 ± 15.9 and 50.8 ± 21.3 points, respectively. The social functioning domain presented a strong positive correlation (r = 0.760) with the mental health domain, and eight moderate correlations (0.400 ≤ r ≥ 0.699) were found between the different domains of the questionnaire. The functional capacity domain and the physical component presented a moderate negative correlation with the WHR (r = -0.402 and r = -0.407, respectively). After adjustment, the WHR was inversely associated with the physical component (β = -1.197; p = 0.002). Conclusion: In adults with obesity, important correlations were observed between the physical and mental components of quality of life, and the waist/height ratio was the only anthropometric indicator correlated and associated with the physical component of the outcome.

Resumo Introdução: A obesidade compromete a qualidade de vida física e mental em função do excesso de peso corporal. Entretanto poucos estudos se propuseram a compreender a influência dos diferentes indicadores antropométricos na qualidade de vida dessa população. Objetivo: Correlacionar os componentes físico e mental da qualidade de vida e verificar a sua associação com diferentes indicadores antropométricos em adultos com obesidade. Métodos: Realizou-se um estudo transversal com adultos com obesidade (índice de massa corporal [IMC] ≥ 30kg/m²). A qualidade de vida foi investigada pelo questionário SF-36, com amplitude de escores de zero (pior cenário) a 100 (melhor cenário para o desfecho). Os indicadores antropométricos foram: IMC, perímetro de cintura, razão cintura/estatura (RCE), massa corporal magra e gorda. Na estatística, empregou-se correlação de Spearman e regressão linear bruta e ajustada para variáveis sociodemográficas. Resultados: Nos 75 sujeitos (nmulheres = 47; µidade = 34,8 ± 7,1 anos), o componente físico apresentou média de 64,5 ± 15,9 pontos e mental de 50,8 ± 21,3 pontos. O domínio de aspecto social apresentou forte correlação positiva (r = 0,760) com o domínio da saúde mental e foram encontradas oito correlações moderadas (0,400 ≤ r ≥ 0,699) entre os distintos domínios do questionário. O domínio capacidade funcional e o componente físico apresentaram moderada correlação negativa com a RCE (r = -0,402 e r = -0,407, respectivamente). Na análise ajustada, a RCE apresentou uma associação inversa com o componente físico (β = -1,197; p = 0,002). Conclusão: Em adultos com obesidade, observou-se importantes correlações entre os componentes físico e mental da qualidade de vida e a razão cintura/estatura foi o único indicador antropométrico correlacionado e associado ao componente físico do desfecho.

[Simultaneity of risk behaviors for obesity in adults in the capitals of Brazil]. / Simultaneidade de comportamentos de risco para a obesidade em adultos das capitais do Brasil.

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.

Association between pubertal development stages and body adiposity in children and adolescents.

BACKGROUND: The study aimed to analyze the association between pubertal development stages and adiposity in children and adolescents. METHODS: Cross-sectional study conducted in 2007 in Florianópolis, Brazil, with 2339 schoolchildren 32 aged 8 to 14 years old (1107 males). The outcome (adiposity) was evaluated using Z score and 33 percentilee values > = 85 of four skinfolds (triceps, subscapular, suprailiac and calf) and waist 34 circumference. Total body adiposity (Z score of the sum of skinfolds), central adiposity (Z score 35 of waist circumference) and peripheral adiposity (Z scores of triceps and calf skinfolds) were 36 estimated. Pubertal development stages was self-assessed according to Tanner stages of development. Thirty-seven Children and adolescents were classified according to tertiles of age for each pubertal development stages 38 stage - early, normal and late. Statistical analysis was performed using univariate and 39 multivariate Poisson regression models. RESULTS: Children and adolescent from both sexes with early pubertal development stages presented higher prevalence of central adiposity (waist circumference), with adjusted prevalence ratio (CI 95%) of 2.21 (1.12; 4.35) for males and 2.18 (1.04; 4.57) for females (reference group: normal pubertal development stages). Among females, there was a reduction in the prevalence of excess adiposity with decreased occurrence of early pubertal development stages. There was a strong relationship between adiposity and pubertal development stages. CONCLUSIONS: Excess adiposity was higher in both sexes for those with early pubertal development stages.

[Fruit and vegetable consumption over a decade among adolescents in the State of Santa Catarina, Brazil]. / Consumo de frutas e verduras por adolescentes catarinenses ao longo de uma década.

Understanding the changes in the trends of fruit and vegetable consumption among adolescents is important in order to implement public health actions. The scope of this article is to investigate the changes over a ten-year period in the daily fruit and vegetable consumption among adolescents from Santa Catarina, according to sex, age and housing area. It is a secondary analysis of a panel survey entitled "Lifestyle and Risk Behavior of Adolescents in the State of Santa Catarina, Brazil (ComPAC)." Adolescents (15-19 years of age) of state schools in 2001 (n=5.028) and 2011 (n=6.529) answered a questionnaire about fruit and vegetable consumption as well as about sociodemographic aspects. Descriptive statistics and logistic regression were applied, according to sex, age and housing area. There was a decrease in daily fruit (39.1% and 16.6%) and vegetable (40.1% and 20.6%) consumption. Different prevalence levels were observed when analyzing subgroups, mainly among girls. From 2001 to 2011, daily vegetable consumption among boys and adolescents in rural areas remained the same. The decrease in daily consumption of fruit and vegetables among adolescents aged 15 to 19 in Santa Catarina highlights the need for the development of strategies to reverse this scenario.

Comparison of linear periodized and non-periodized combined training in health markers and physical fitness of adults with obesity: Clinical trial protocol.

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).

Influence of sexual maturation status on the relationship between body adiposity indicators and age: a cross-sectional study.

OBJECTIVES: To determine the influence of sexual maturation status on adiposity indicators of children and adolescents. RESULTS: 2412 individuals participated, 1285 (47.4%) males and 1408 (52.6%) females. There was moderate to weak correlation between age and adiposity indicators for both sexes. By analyzing the relationship between age and body fat indexes adjusted for Sexual Maturation Status, several changes were observed, mainly in girls. Precocious maturation was associated with increased adiposity indicators in girls, whereas late maturation was associated with decreased adiposity indicators in both sexes. Precocious maturation was associated with increased adiposity indicators in girls, whereas late maturation was associated with decreased adiposity indicators in both sexes.

Body mass index and association with use of and distance from places for physical activity and active leisure among schoolchildren in Brazil. Cross-sectional study.

BACKGROUND: We evaluated associations between use of public places for physical activity and active leisure (PAAL) and their distances from subjects' homes and indicators of overweight and obesity, among schoolchildren from different socioeconomic levels, in the city of Florianópolis, Brazil. DESIGN AND SETTING: Cross-sectional study conducted on a sample of 2,152 schoolchildren aged 7 to 14 years, enrolled at 30 public and private schools. METHODS: The exposure variables were the use of public places for PAAL in the neighborhood and their distance from schoolchildren's homes. The outcomes were body mass index (BMI) and waist circumference (WC). Univariate and multivariate linear regression analyses were conducted according to income strata. RESULTS: Among the schoolchildren from low-income families, living closer to parks/playgrounds was associated with lower BMI (ß = -2.15; 95% confidence interval, CI = -2.53; -1.77) and lower WC (ß = -0.11 95% CI = -0.17; -0.05), while living at these distances from football pitches was associated with higher BMI (ß = 1.73; 95% CI = 0.31; 3.15) and larger WC measurements (ß = 0.03; 95% CI = 0.005; 0.14). Among the schoolchildren in low-income groups, living at an intermediate distance from beaches was associated with lower BMI (ß = -1.10; 95% CI = -1.61; -0.59). CONCLUSION: Living closer to parks/playgrounds was associated with lower BMI and WC among schoolchildren from low-income families. Living closer to football pitches was associated with higher BMI and WC among these schoolchildren. Living at intermediate distances from beaches was associated with lower BMI among these schoolchildren.

ABSTRACT BACKGROUND: We evaluated associations between use of public places for physical activity and active leisure (PAAL) and their distances from subjects' homes and indicators of overweight and obesity, among schoolchildren from different socioeconomic levels, in the city of Florianópolis, Brazil. DESIGN AND SETTING: Cross-sectional study conducted on a sample of 2,152 schoolchildren aged 7 to 14 years, enrolled at 30 public and private schools. METHODS: The exposure variables were the use of public places for PAAL in the neighborhood and their distance from schoolchildren's homes. The outcomes were body mass index (BMI) and waist circumference (WC). Univariate and multivariate linear regression analyses were conducted according to income strata. RESULTS: Among the schoolchildren from low-income families, living closer to parks/playgrounds was associated with lower BMI (β = -2.15; 95% confidence interval, CI = -2.53; -1.77) and lower WC (β = -0.11 95% CI = -0.17; -0.05), while living at these distances from football pitches was associated with higher BMI (β = 1.73; 95% CI = 0.31; 3.15) and larger WC measurements (β = 0.03; 95% CI = 0.005; 0.14). Among the schoolchildren in low-income groups, living at an intermediate distance from beaches was associated with lower BMI (β = -1.10; 95% CI = -1.61; -0.59). CONCLUSION: Living closer to parks/playgrounds was associated with lower BMI and WC among schoolchildren from low-income families. Living closer to football pitches was associated with higher BMI and WC among these schoolchildren. Living at intermediate distances from beaches was associated with lower BMI among these schoolchildren.

Clustering of unhealthy food habits and its association with socioeconomic factors among Brazilian workers / Agrupamento de hábitos alimentares não saudáveis e sua associação com fatores socioeconômicos entre trabalhadores brasileiros

ABSTRACT Objective Investigate the clustering of four unhealthy food habits (low intake of fruits, low intake of vegetables, high intake of candy, and high intake of fried snacks), and to identify the association between the number of these clustered habits and sociodemographic variables. Methods This was a cross-sectional representative study of industrial workers from 24 Federative Units in Brazil conducted between 2006 and 2008. The low weekly intake of fruits and vegetables (<5 days/week) and high weekly intake of candy and fried snacks (≥5 days/weeks) were evaluated using a validated questionnaire. Simultaneity was analyzed with stratification by sex, calculating the Observed (O) and Expected (E) prevalence and the O/E ratio for each of the 16 possible food intake combinations. Results Among the 47,477 workers studied, in both men and women, the simultaneous presence of high weekly intake of candy and fried snacks(O/E=3.58; 95%CI=3.12-4.10 and O/E=2.17; 95%CI=1.76-2.62) and of the four unhealthy food habits (O/E=2.32; 95%CI=2.01-2.66 and O/E=4.02; 95%CI=3.44-4.65) exceeded the expected percentages if these foods were consumed separately. When compared to subjects without or with only one unhealthy food habit, the combination of the four negative dietary behaviors was more frequent among women, workers with a lower education level, and those living without a partner. Conclusion Unhealthy food habits tend to cluster together in both sexes, suggesting a strong interaction, particularly for the four unhealthy food habits together, especially among women, less educated workers and without a partner.

RESUMO Objetivo Investigar o agrupamento de quatro hábitos alimentares não saudáveis (baixo consumo de fruta, baixo consumo de verdura, alto consumo de doce e alto consumo de salgadinho), e identificar a associação entre a quantidade desses hábitos agrupados e variáveis sociodemográficas. Métodos Esse foi um estudo transversal e representativo de trabalhadores das indústrias de 24 Unidades Federativas do Brasil, realizado de 2006 e 2008. Os baixos consumos semanais de fruta e verdura (<5 dias/semana) e os altos consumos semanais de doce e salgadinho (>5 dias/semana) foram avaliados por questionário validado. A simultaneidade foi analisada com estratificação por sexo, conforme a prevalência Observada (O), Esperada (E), Razão (O/E) para cada uma das 16 combinações possíveis de consumo alimentar. Resultados Nos 47.477 trabalhadores investigados, tanto em homens quanto em mulheres, respectivamente, a presença simultânea alto consumo semanal de doce e salgadinho (O/E=3,58; IC95%=3,12-4,10 e O/E=2,17; IC95%=1,76-2,62) e dos quatro hábitos alimentares não saudáveis juntos (O/E=2,32; IC95%=2,01-2,66 e O/E=4,02; IC95%=3,44-4,65) foram aquelas que mais excederam os percentuais esperados, caso esses alimentos fossem ingeridos de forma independente. Comparados aos sujeitos com nenhum ou um hábito alimentar não saudável, a combinação de quatro comportamentos alimentares negativos foi mais frequente entre as mulheres, trabalhadores com menor nível de escolaridade e que viviam sem companhia. Conclusão Hábitos alimentares não saudáveis tendem a se agrupar em ambos os sexos, sugerindo uma forte interação, especialmente para os quatro hábitos alimentares não saudáveis em conjunto, principalmente nas mulheres, trabalhadores com menor escolaridade e que vivem sem parceiro.

Association between screen time and dietary patterns and overweight/obesity among adolescents / Associação entre tempo de tela e padrões alimentares com sobrepeso/obesidade em adolescentes

ABSTRACT Objective The association between screen time and dietary patterns and overweight/obesity among adolescents was analysed in this study. Methods In this cross-sectional study, 963 Brazilian adolescents, aged between 11 and 14 years were evaluated. Body mass index was used to assess overweight/obesity. Dietary patterns and screen time were assessed using qualitative questionnaires. Principal component analysis was used to obtain dietary patterns. Confounder variables were: type of school (public or private), sexual maturation, mother's weight and mother's education. The Chi-square test was used for the crude analysis; for the adjusted analysis was used Poisson regression with sample weighting. Results Overweight/obesity prevalence was 29.8% and statistically higher among boys (34.7%). Higher screen time prevalence was 39.1%. The dietary patterns obtained were: obesogenic; coffee and dairy products; traditional Brazilian meal; fruit and vegetables; bread and chocolate milk. The dietary pattern that more closely represented student food consumption was the obesogenic pattern. Screen time was not significantly associated with overweight/obesity. The obesogenic pattern (in both sexes), the coffee and dairy products pattern, and the bread and chocolate milk pattern (only in girls), were inversely associated with overweight/obesity. In this study, dietary patterns influenced overweight/obesity, although in some cases, in an inverse way from what expected. Conclusion A high prevalence of overweight/obesity and a high proportion of screen time activities among the adolescents were observed. Our results indicate a high consumption of unhealthy dietary pattern among adolescents.

RESUMO Objetivo Analisar a associação entre tempo de tela e padrões alimentares com sobrepeso/obesidade em adolescentes de Florianópolis, Santa Catarina, Brasil. Métodos Estudo transversal com amostra probabilística de 963 adolescentes de 11 a 14 anos de idade matriculados em escolas públicas e privadas do município. O sobrepeso/obesidade foi avaliado por meio do índice de massa corporal e o consumo alimentar do dia anterior por meio da aplicação de questionário qualitativo. Análise de Componentes Principais foi utilizada para obtenção dos padrões alimentares. Os fatores de confusão considerados foram: tipo de escola, maturação sexual, peso e escolaridade da mãe. Usou-se teste Qui-quadrado e regressão de Poisson nas análises bruta e ajustada, respectivamente. Resultados A prevalência de sobrepeso/obesidade foi de 29,8%, sendo estatisticamente maior nos meninos (34,7%). A prevalência de alto tempo de tela foi de 39,1%. Os padrões alimentares obtidos foram: obesogênico; café e produtos lácteos; refeição tradicional brasileira; frutas e vegetais; pão e achocolatado. O padrão de consumo alimentar que melhor representou o consumo dos adolescentes nessa amostra foi o obesogênico. Não houve associação estatisticamente significativa entre tempo de tela e sobrepeso/obesidade. Foram inversamente associados com sobrepeso/obesidade os padrões: obesogênico; café e produtos lácteos; e pão e achocolatado (apenas em meninas). Padrões de consumo alimentar influenciaram a prevalência de sobrepeso/obesidade, porém, em alguns casos, de maneira contrária ao esperado. Conclusão Observou-se alta prevalência de sobrepeso/obesidade e alta frequência de atividades sedentárias. Os resultados sugerem alto índice de padrão alimentar não saudável pelos adolescentes.

Association of sexual maturation with excess body weight and height in children and adolescents.

BACKGROUND: Studies addressing the influence of early sexual maturation on the excess of body weight and height of children and adolescents are scarce. The aim of the study was to analyze the association of sexual maturation with excess body weight and height in children and adolescents. METHODS: This was a cross-sectional study performed in Florianópolis city, Brazil, in 2007, with 2339 school children, aged 8-14 years (1107 males). Selection was based on a probabilistic, cluster-stratified sampling technique. School children were classified according to the presence of excess body weight, using sex- and age-specific body mass index (BMI) cutoff points. Z-scores were calculated from height and BMI data. Sexual maturation was self-assessed according to Tanner stages of development. Subjects were ranked based on tertiles of sexual maturation (early, normal and late) for each stage of development. Poisson and linear regression models were used. RESULTS: Compared to the reference group (normal sexual maturation), early maturing females had higher prevalence of excess weight (adjusted prevalence ratio: 1.70; 95% CI: 1.24 to 2.33) and increased height-for-age (adjusted ß: 0.37; 95% CI: 0.14 to 0.59), while late maturing females had lower prevalence of excess weight (adjusted prevalence ratio: 0.57; 95% CI: 0.37 to 0.87) and decreased height-for-age (adjusted ß: -0.38; 95% CI: -0.56 to -0.20). In males, early and late sexual maturation were associated with increased (adjusted ß: 0.37; 95% CI: 0.14 to 0.59) and decreased (adjusted ß: -0.38; 95% CI: -0.56 to -0.20) height-for-age, respectively. CONCLUSION: Early sexual maturation is associated with excess body weight in females and with greater height-for-age in both sexes.

Median ages at stages of sexual maturity and excess weight in school children.

BACKGROUND: We aimed to estimate the median ages at specific stages of sexual maturity stratified by excess weight in boys and girls. MATERIALS AND METHOD: This was a cross-sectional study made in 2007 in Florianopolis, Brazil, with 2,339 schoolchildren between 8 to 14 years of age (1,107 boys) selected at random in two steps (by region and type of school). The schoolchildren were divided into: i) those with excess weight and ii) those without excess weight, according to the WHO 2007 cut-off points for gender and age. Sexual maturity was self-evaluated by the subjects according to the Tanner sexual development stages, and utilizing median ages for the genitalia, breasts, and pubic hair stages. RESULTS: In the boys with excess weight, precocity was observed in the stages 4 for genitals and pubic hair and 2 for pubic hair, with the values for excess and normal weight. The median ages at the beginning of puberty (stage 2-sexual development) for boys and girls in Florianopolis were 10.8 and 10.3 years, respectively. CONCLUSION: Excess weight is associated with lower median ages in the sexual maturity stages in boys and girls and that it should be taken into account when evaluating sexual maturity in children and adolescents.

Clustering of risk factors for non communicable diseases in adults from Florianopolis, SC.

OBJECTIVE: To investigate clustering patterns of health risk behaviors for non communicable diseases and its associated factors. METHODS: a Random telephone survey with 1,996 adults from Florianopolis, SC, was conducted in 2005. Tobacco use, high alcoholic intake episodes, fruit consumption and physical inactivity were investigated. Clustering was examined by the ratio between observed and expected prevalence of each of the 16 possible combinations. These clustered risk factors comprised the main outcome and binomial and multinomial logistic regression was conducted to examine socio-demographic correlates. RESULTS: 43% of men and 36.6% of women clustered at least two health risk factors. Three (19.2%; CI 95% 16.7 - 21.7) and five (9.8%; CI 95% 8.0 - 11.6) specific combinations exceed the expected prevalence, respectively, in men and women. Women with low schooling level and older were more likely to cluster health risk behaviors. CONCLUSION: although men showed higher prevalence of single health risk behavior and its combinations, women presented more specific combinations that clustered above the expected. Knowledge on the clustering pattern of these health risk behaviors may guide the design of more effective health promotion initiatives.
