Excesso de peso, obesidade abdominal e fatores associados em servidores técnico administrativos da Univesidade Federal de Santa Catarina

Dissertação (mestrado) - Universidade Federal de Santa Catarina, Centro de Desportos, Programa de Pós-Graduação em Educação Física, Florianópolis, 2013O objetivo deste estudo foi verificar a prevalência de excesso de peso e obesidade abdominal, segundo diferentes indicadores antropométricos e os fatores associados, em servidores técnico administrativos da Universidade Federal de Santa Catarina (UFSC). Trata-se de um estudo transversal, realizado com 615 servidores da UFSC. Os indicadores antropométricos analisados foram o índice de massa corporal (IMC), circunferência da cintura (CC) e razão cintura estatura (RCEst), variáveis sociodemográficas e fatores de risco à saúde. As análises estatísticas abrangeram o teste t de student, teste U de Mann-Witney, regressão de Poisson, regressão logística binária e regressão multinomial. A prevalência de excesso de peso foi de 63,6% e 49,7% (IMC) e de obesidade abdominal de 33,5%, 42,4% (CC), 61,8% e 40,6% (RCEst), entre homens e mulheres respectivamente. Além disso, 33,2% dos homens e 34,3% das mulheres apresentaram inadequação de acordo com os três indicadores antropométricos analisados. Ter mais de 40 anos identificou maior probabilidade de excesso de peso e obesidade abdominal entre homens (IMC e RCEst) e mulheres (IMC, CC e RCEst). Menor prevalência de excesso de peso foi verificada entre os homens com nível econômico intermediário (RP=0,68, IC95%:0,52; 0,89) e alto (RP=0,68, IC95%:0,48; 0,98) e maior prevalência entre as mulheres casadas (RP=1,42, IC95%:1,04; 1,95). A probabilidade de ter RCEst elevada foi menor para as mulheres com oito anos de escolaridade ou menos (RP=0,52, IC95%:0,37; 0,74). Os homens insuficientemente ativos estiveram mais expostos à inadequação de acordo com IMC, CC e RCEst simultaneamente (OR=2,36, IC95%:1,01; 5,52), as mulheres ativas menos chance de ter um indicador inadequado (OR=0,30; IC95%:0,10; 0,90) e as mulheres com alimentação inadequada maior chance de apresentar os três indicadores inadequados simultaneamente (OR=2,85; IC95%:1,57; 5,15). Esses resultados indicam a necessidade de intervenções para prevenção e tratamento do excesso de peso e obesidade abdominal, enfatizando a importância da aquisição de hábitos saudáveis.Abstract : The aim of this study was to determine the prevalence of overweight and abdominal obesity, according to different anthropometric indicators and associated factors in technical administrative servants at the Federal University of Santa Catarina (UFSC). This is a cross-sectional study with 615 UFSC servants. The anthropometric indicators analyzed were body mass index (BMI), waist circumference (WC) and waist/height ratio (WHtR), sociodemographic variables and health risk factors. Statistical analyses included the Student t-test, U Mann-Whitney test, Poisson regression, binary logistic regression and multinomial regression. The prevalence of overweight was 63.6% and 49.7% (BMI) and abdominal obesity was 33.5%, 42.4% (WC), 61.8% and 40.6% (WHtR) among men and women respectively. Furthermore, 33.2% of men and 34.3% of women had inadequate indicators according to the three anthropometric indicators analyzed. Having more than 40 years of age was identified as a greater likelihood of overweight and obesity among men (BMI and WHtR) and women (BMI, WC and WHtR). Lower prevalence of overweight was found among men with intermediate (OR = 0.68, CI 95%: 0.52, 0.89) and high economic level (OR = 0.68, CI 95%: 0.48, 0.98) and higher prevalence among married women (OR = 1.42, CI 95%: 1.04, 1.95). The likelihood of having high WHtR was lower for women with eight years of schooling or less (OR = 0.52, CI 95%: 0.37, 0.74). Insufficiently active men were more exposed to inadequate BMI, WC and WHtR simultaneously (OR = 2.36, CI 95%: 1.01, 5.52); physically active women were less likely to have inadequate indicator (OR = 0.30, CI 95%: 0.10, 0.90) and women with poor diet had increased risk of having all three indicators inadequate simultaneously (OR = 2.85, CI 95%: 1.57, 5.15). These results indicate the need of interventions for prevention and treatment of overweight and obesity, emphasizing the importance of acquiring healthy habits

Avaliação postural, aptidão física relacionada à saúde e avaliação da imagem corporal de adolescentes praticantes de dança: um estudo de caso.

Objetivou-se com este estudo investigar os desvios posturais, níveis de aptidão física relacionada à saúde e imagem corporal de adolescentes praticantes de dança. Para tanto, realizou-se uma pesquisa descritiva do tipo estudo de caso. Participaram da pesquisa 10 dançarinas do Instituto São José da cidade de Santa Maria – RS, com no mínimo 5 meses de prática. Para a coleta de dados os sujeitos da pesquisa responderam um questionário sobre Imagem Corporal, uma entrevista sobre a maturação sexual, teste de flexibilidade e Índice de Massa Corporal - IMC e avaliação postural. Utilizou-se uma estatística descritiva dos dados obtidos, para verificar a média () e desvio padrão (dp); uma análise de freqüência e porcentagem a fim de verificar possíveis relações entre as variáveis estudadas. Os resultados demonstram que mesmo possuindo um bom Índice de Massa Corporal, localizado na faixa para boa saúde, a insatisfação perante a imagem corporal é superior à aceitação. Também foram encontrados diversos desvios posturais e escolioses que podem interferir negativamente na aptidão física das adolescentes

Intervenção multicomponente na escola: efeito em indicadores de adiposidade em adolescentes, mediadores e preditores de desistência

Tese (doutorado) - Universidade Federal de Santa Catarina, Centro de Desportos. Programa de Pós-Graduação em Educação Física, Florianópolis, 2017O objetivo deste estudo foi analisar o efeito e mediadores de uma intervenção multicomponente nos indicadores de adiposidade e identificar os fatores associados à desistência da intervenção, em adolescentes do 6º ao 9º ano, de escolas municipais de Florianópolis, SC. O estudo quase-experimental foi conduzido em duas escolas (grupo intervenção [GI] e grupo controle [GC]). O tamanho da amostra estimado para o efeito no índice de massa corporal (IMC) foi de 151 adolescentes em cada grupo. A intervenção planejada com duração de 14 semanas foi composta por quatro componentes: 1) aumento da prática de atividade física (AF) moderada a vigorosa, exercícios de força e flexibilidade nas aulas de Educação Física (EF); 2) recreios ativos; 3) sessões educativas sobre AF e saúde; nutrição e imagem corporal e 4) materiais educativos para adolescentes e pais. O GC não teve alteração nas atividades escolares. O efeito da intervenção foi estimado para o IMC, perímetro da cintura (PC), somatórios das dobras cutâneas (DC) do tríceps e subescapular (?2DC) e massa gorda (estimada pela impedância bioelétrica [BIA]). A desistência na intervenção foi analisada considerando os adolescentes que desistiram, ausentes e a frequência na intervenção. Informações sociodemográficas, AF, tempo de tela, consumo alimentar, percepção de saúde, atitudes em relação à AF, autoeficácia para AF, percepção do ambiente escolar, imagem corporal e autoestima foram obtidas por questionário. A análise de regressão logística binária, covariância e do produto dos coeficientes ab foram utilizadas para as análises dos preditores de desistência, do efeito da intervenção e de mediação, respectivamente. A amostra final foi composta por 478 adolescentes (GI= 283 e GC= 195). O percentual de desistência na intervenção foi de 32,6%. Na amostra total verificou-se maior chance de desistência com o aumento da idade (1,40; IC95%: 1,11; 1,77), do IMC (1,16; IC95%: 1,01; 1,36) e atitudes negativas em relação à AF (0,87; IC95%: 0,78; 0,98). Para os adolescentes com excesso de peso, além do aumento da idade (2,47; IC95%: 1,28; 4,74), o aumento da condição econômica (1,21; IC95%: 1,04; 1,41), da percepção positiva do ambiente escolar (1,44; IC95%: 1,04; 1,99) e o turno de estudo vespertino (5,15; IC95%: 1,25; 21,16) estiveram associados à desistência. A intervenção apresentou efeito na massa gorda (tamanho do efeito [TE]: -0,56; IC95%: -0,91; -0,21). Quando analisado o efeito da intervenção em subgrupos verificou-se efeito no IMC na faixa etária de 10 a 12 anos (TE: -0,32; IC95%: -0,60; -0,03) e classificados com magreza no início do estudo (TE: 0,84; IC95%: 0,16; 1,52). A AF, tempo de tela e alimentação não mediaram o efeito da intervenção no IMC, PC e ?2DC. Em conclusão, fatores sociodemográficos, intrapessoais e ambientais foram preditores de desistência na intervenção e os fatores associados diferiram de acordo com a classificação do IMC. Com relação ao efeito da intervenção houve menor incremento da massa gorda no GI, para a amostra total e no IMC aos 10 a 12 anos. Nos adolescentes classificados com magreza foi verificado maior incremento no IMC. Nenhuma variável comportamental analisada apresentou-se como mediadora do efeito da intervenção.Abstract: The objectives of this study were to analyze the effect and mediators ofa multicomponent intervention on adiposity indicators and identify thefactors associated with the dropout of intervention, in adolescents from6th to 9th grades, in municipal schools in Florianópolis, SC. The quasiexperimentalstudy was conducted in two schools (intervention group[IG] and control group [CG]). The estimated sample size for body massindex (BMI) effect was 151 adolescents in each group. The 14-weekplanned intervention consisted of four components: 1) increasedmoderate to vigorous physical activity (PA), strength and flexibilityexercises in Physical Education (PE) classes; 2) active recess; 3)educational sessions on PA and health; nutrition and body image and 4)educational materials for adolescents and parents. CG had no change inschool activities. The effect of intervention was estimated for BMI,waist circumference (WC), sum of triceps and subscapular skinfolds(S2SF) and fat mass (estimated by bioelectrical impedance [BIA]).Intervention dropout was analyzed considering the adolescents whodropout, absent and the frequency in the intervention. Sociodemographicinformation, PA, screen time, food consumption, healthperception, attitudes towards PA, self-efficacy for PA, perception of theschool environment, body image and self-esteem were obtained using aquestionnaire. Binary logistic regression, covariance analysis and theproduct of coefficients ab were used for the analysis of the predictors ofdropout, effect of intervention and mediation, respectively. The finalsample consisted of 478 adolescents (GI = 283 and GC = 195). Thedropout rate was 32.6%. In the total sample and among adolescents withadequate BMI, there was a greater chance of dropout with increasingage (1.40, 95% CI: 1.11, 1.77), BMI (1.16, 95% CI: 1.01, 1.36) andnegative attitude towards PA (0.87, 95% CI: 0.78, 0.98). For overweightadolescents, in addition to increasing age (2.47, 95% CI: 1.28, 4.74),increase economic level (1.21, 95% CI: 1.04, 1.41), better perception ofthe school environment (1.44, 95% CI: 1.04, 1.99), and attending theafternoon study shift (5.15, 95% CI: 1.25, 21.16) were associated withdropout. Intervention had an effect on fat mass (effect size [ES]: -0.56;95% CI: -0.91; -0.21). When the effect of intervention on subgroups wasanalyzed, there was an effect on BMI in the age group of 10-12 years(ES: -0.32; 95% CI: -0.60; -0.03) and classified as thin at baseline (ES:0.84, 95% CI: 0.16, 1.52). PA, screen time and food consumption didnot mediate the effect of intervention on BMI, WC and S2SF. Inconclusion, socio-demographic, intrapersonal and environmental factorswere intervention predictors of dropout and the associated factorsdiffered according to the BMI category. Regarding the effect of theintervention, there was a smaller fat mass increment in the IG, for thetotal sample and on BMI at 10 to 12 years. In the adolescents classifiedwith thinness there was an increase in BMI. No behavioral variablesanalyzed were mediators in the present study

<b> Overweight, abdominal obesity and associated factors in technical administrative servants</b>

The objectives of this study were to determine the prevalence rates of excess weight and abdominal obesity among technical and administrative staff at the Universidade Federal de Santa Catarina (UFSC) using a range of different anthropometric indicators and to identify sociodemographic factors associated with these rates. This was a cross-sectional study of 615 members of staff at UFSC (283 men and 332 women). The following anthropometric indicators were analyzed: body mass index (BMI), waist circumference (WC) and waist to height ratio (WHtR). The following sociodemographic variables were also analyzed: age, sex, skin color, marital status, socioeconomic status, educational level and employment grade. Statistical analysis was conducted using Student’s t test, the Mann-Whitney U test and Poisson regression (with a 95% confidence interval). Prevalence rates for men and women respectively were as follows; excess weight: 63.6% and 49.7% (BMI); abdominal obesity (WC): 33.5% and 42.4%; and abdominal obesity (WHtR): 61 .8% and 40.6%. Age greater than 40 years was associated with a higher probability of excess weight and abdominal obesity in men (by BMI and WHtR) and women (by BMI, WC and WHtR). Women who had spent 8 years or fewer in education had lower probabilities of excess weight (PR=0.67; 95%Cl=0.49; 0.94) and abdominal obesity, by both WC (PR=0.62; 95%Cl=0.44; 0.90) and WHtR (PR=0.49; 95%Cl=0.39; 0.64). These results indicate an elevated prevalence of excess weight and abdominal obesity and show that the factors associated with these outcomes vary by sex and depending on the anthropometric indicator analyzed

Stages of Behavior Change for physical activity and associated factors among technicaladministrative servers of a federal university

The benefits that the regular practice of physical activity (PA) provides to health and its importance in preventing and fighting chronic diseases. The aim of this study was to identify the Stages of Behavior Change (SBC) for PA among technicaladministrative servers and its association with sociodemographic and health risk factors. This cross-sectional study investigated 622 technical-administrative servers (337 women) from a Brazilian federal university. SBC for PA, sociodemographic information (gender, age, marital status and educational level) and health risk factors (inadequate eating habits, excessive alcohol consumption, smoking, commuting and PA at work) were collected through questionnaires. Multinomial regression with adjustment for the hierarchical level was applied and significance level of 5% was adopted. The distribution of technical-administrative servers in SBC for PA identified prevalence of 9.1% and 6.5% in the pre-contemplation stage, 24.6% and 33.5% in contemplation, 33.3% and 22 6% in preparation, 5.6% and 12.2% in action and 27.4% and 25.2% in maintenance stages between men and women, respectively. Lower odds ratio of being in the preparation stage was identified among women (OR=0.62; CI95%=0.41; 0.93) while those with inadequate eating habits were more odds to be in the “pre-contemplation + contemplation” (OR=2.77; CI95%=1.85; 4.15) and preparation stages (OR=1.75; CI95%=1.12; 2.70). Over 60% of technical-administrative servers are insufficiently active (pre-contemplation, contemplation and preparation stages) and factors associated with SBC were female sex and inadequate eating habits

Exposure to simultaneous sedentary behavior domains and sociodemographic factorsassociated in public servants

<div><p>Abstract Exposure to sedentary behavior may contribute to health problems. This study aimed to estimate the prevalence of exposure to simultaneous sedentary behavior domains and verify associated sociodemographic characteristics among technical and administrative servers of a Brazilian university. This is a cross-sectional epidemiological study carried out with 623 technical and administrative servers. Sedentary behavior was identified through a questionnaire in the following domains: commuting (active / passive), sitting time at work, daily time spent watching television and computer use (≥3 hours / day). Sociodemographic variables were age, sex and educational level. The prevalence of servers that had one, two, three and four simultaneous sedentary behavior was 28.4%, 43.2%, 22.5% and 4.3%, respectively. Women were more likely to have three sedentary behavior simultaneously (OR = 1.61, CI 95% = 1.02, 2.56). Servers with 9-11 years of schooling were less exposed to two (OR = 0.27, CI 95% = 0.17, 0.44), three (OR = 0.39, CI 95% = 0.23, 0.66) and four (OR = 0.22, CI 95% = 0.07; 0.69) sedentary behavior simultaneously and those over 12 years of schooling were less likely of having two (OR = 0.22, CI 95% = 0.10; 0.49) and three (OR = 0.15, CI 95% = 0.05, 0.46) sedentary behavior simultaneously. More than half of servers have two sedentary behavior during the week. Having sedentary behavior in more than one domain simultaneously was associated with sex and educational level.</p></div
