Sono e adolescência: quantas horas os adolescentes precisam dormir?

Objetivo Determinar a especificidade e a sensibilidade de uma medida para apontar o melhor ponto de corte para a duracao de sono como preditor da sonolencia diurna excessiva em adolescentes. Metodos Participaram do estudo 1.359 adolescentes, com idades de 14 a 21 anos, de duas cidades do sul do Brasil, que responderam a questionario de habitos de sono e sonolencia diurna. Utilizou-se a Receiver Operating Characteristic para estimar a capacidade preditiva da duracao de sono para a sonolencia diurna excessiva. Resultados A media de duracao do sono para os adolescentes com sonolencia diurna excessiva foi de 7,9 horas e para aqueles sem sonolencia diurna excessiva foi de 8,33 horas (p < 0,001). A prevalencia de sonolencia diurna excessiva foi de 35,7%. Foi observada correlacao significativa e negativa entre a duracao do sono e as idades analisadas (p < 0,001). A analise de Receiver Operating Characteristic indicou duracao minima de 8,33 horas como protecao para a sonolencia diurna excessiva. Conclusao Foi observada alta prevalencia de sonolencia diurna excessiva e propoe-se como possivel duracao de sono um minimo de 8,33 horas nos dias com aula para que os adolescentes evitem esse desfecho.

Body weight perception and body weight control behaviors in adolescents

OBJECTIVEnTo investigate the association between the perception of body weight (as above or below the desired) and behaviors for body weight control in adolescents.nnnMETHODSnThis was a cross-sectional study that included 1051 adolescents (aged 15-19 years) who were high school students attending public schools. The authors collected information on the perception of body weight (dependent variable), weight control behaviors (initiative to change the weight, physical exercise, eating less or cutting calories, fasting for 24h, taking medications, vomiting, or taking laxatives), and measured body weight and height to calculate the body mass index and then classify the weight status. Associations were tested by multinomial logistic regression analysis.nnnRESULTSnAdolescents of both sexes who perceived their body weight as below the expected weight took more initiatives to gain weight, and those who perceived themselves as overweight made more efforts to lose weight. In adolescents who perceived themselves as overweight, the behavior of not taking medication was associated with the outcome only in boys (Odds Ratio=8.12), whereas in girls, an association was observed with the variables eating less, cutting calories, or avoiding fatty foods aiming to lose or avoid increasing body weight (Odds Ratio=3.39). Adolescents of both sexes who practiced exercises were more likely to perceive themselves as overweight (male Odds Ratio=2.00; Odds Ratio=1.93 female).nnnCONCLUSIONnThe perception of the body weight as above and below ones expected weight was associated with weight control behaviors, which were more likely to result in initiatives to lose and gain weight, respectively.Objective nTo investigate the association between the perception of body weight (as above or below the desired) and behaviors for body weight control in adolescents.

Fatores associados à insatisfação com a imagem corporal em acadêmicos de Educação Física

Objective To investigate body image dissatisfaction in physical education college students and verify which factors are specifically associated to dissatisfaction with thinness and with overweight. Methods Participated 299 college students (173 men and 126 women) with mean age of 23.14 (4.93) years, of the baccalaureate and degree courses in Physical Education, from a public university of Florianopolis-SC. Through self-applied questionnaire, the academics answered sociodemographic questions, about body image (figure rating scale) and referred their body mass and stature measurements to compute body mass index. Results The prevalence of body image dissatisfaction was 76.6% (27.4% were dissatisfied with thinness and 49.0% with overweight), being higher in females (82.5%). Binary logistic regression analysis revealed association between dissatisfaction with thinness and the variables gender (male) and weight status (normal weight) and between dissatisfaction with overweight and the variables: gender (female), weight status (overweight) and course (degree). Conclusion It is necessary that undergraduate courses have contents aimed to the student health, addressing aspects related to eating behavior, obesity, body image and the implications that it can provide in a future teaching practice.

Fatores sociodemográficos e imagem corporal em adolescentes do ensino médio

The scope of this article is to investigate associations between body image dissatisfaction and sociodemographic indicators among adolescents. Participants included 1126 high school students in the city of Santa Maria in the State of Rio Grande do Sul. Aspects regarding body image dissatisfaction and sociodemographic indicators were analyzed. Association analyses were performed using crude Poisson regression duly adjusted for sex and age. Boys were found to be dissatisfied due to slimness and girls due to excess weight. Adolescents where the parents had less schooling, as well as those from lower socioeconomic classes and with lower income were found to be more likely to have body image dissatisfaction due to slimness. However, those where the parents had completed higher education and those living in the downtown area were more likely to have body image dissatisfaction due to excess weight. Sociodemographic indicators are closely associated with body image dissatisfaction. Body image dissatisfaction due to slimness can be explained by the lower level of schooling of the parents, lower socioeconomic class and lower income. Dissatisfaction due to excess weight can be explained by the higher schooling of the parents and the fact of living in the downtown area.

ADAPTAÇÃO TRANSCULTURAL PARA O PORTUGUÊS DE UM INSTRUMENTO PARA AVALIAÇÃO DE PROVOCAÇÕES DURANTE A ATIVIDADE FÍSICA/ESPORTIVA EM ADOLESCENTES BRASILEIROS

ABSTRACT Objective: To translate and adapt a questionnaire aimed to evaluate teasing during the practice of physical/sports activities in the adolescent population. Methods: The whole process had six stages: four translations, elaboration of a synthesis version, two back-translations, evaluation by a committee of experts, test of pre-final version with the target population, and presentation of final version to a committee of experts. Thirty-eight adolescents aged between 11 and 18 years participated in the pre-final version test, all of them from the 6th grade of elementary school to senior year of high school in a public school of the state of Santa Catarina. Results: The steps were strictly followed and then the need for change in the instrument emerged. The questions were altered according to discrepancies observed in back-translations, as well as suggestions by specialists to improve understanding and/or clarity and notes of adolescents participating in the pre-final test. Conclusions: The instrument was translated into Portuguese and adapted to the Brazilian context according to the reality and culture of adolescents aged 11 to 18 years old, with possible understanding failures in younger age groups.

ASSOCIATION BETWEEN PERCEIVED STRESS IN ADOLESCENCE, BODY WEIGHT AND ROMANTIC RELATIONSHIPS

ABSTRACT Objective: To analyze the association between perceived stress in adolescence, body weight and romantic relationships. Methods: Participants were 2,571 adolescents (56.1% female), with mean age of 16.6±1.2 years, who were students of public schools in Amazonas. The adolescents answered a questionnaire with sociodemographic questions (sex, age group, school year, study shift, maternal schooling and family income) and related to body weight dissatisfaction, romantic relationships (identified by the relationship status - with or without a partner) and perceived stress (dependent variable). Binary Logistic Regression was used to test the association between perceived stress, body weight dissatisfaction and romantic relationships. The analysis was adjusted by sex and age group. Results: The prevalence of perceived stress was 19.0% (95% confidence interval - 95%CI 17.5-20.3), and was higher among girls (23.2%; 95%CI 21.5-24.5) than boys (13.6%; 95%CI 12.2-14.7). Adolescents with partners (OR 1.76; 95%CI 1.14-2.71) and those who wanted to lose body weight (OR 1.53; 95%IC 1.18-1.98) were more likely to perceive themselves as stressed. Conclusions: There was an association between perceived stress, relationship status and body weight dissatisfaction. Regardless of sex and age group, the adolescents with a partner and those who wanted to lose weight were more likely to perceive themselves as stressed. Girls should receive special attention, as well as adolescents with partners and those who want to lose body weight.

Prática de caminhada, atividade física moderada e vigorosa e fatores

Physical inactivity is considered a major cause of morbidity and mortality worldwide. The aim of this study was to analyze the association of socio demographic fac- tors, weight status, body adiposity and sedentary behavior with the practice of walking and moderate and vigorous physical activity in adolescents. This cross-sectional study included 631 adolescents (413 girls) aged 14-17 years. A self-administered questionnaire was used to collect data. Boys showed longer time of practice of walking and vigorous activity than girls. Adolescents of high economic level were more involved in vigorous activities. Overweight girls and adolescents showed, respectively, 98 and 138 minutes/week less of practice of walking when compared to boys and normal-weight adolescents. Adolescents with high body adiposity had 100 minutes/week more of practice of walking in relation to adolescents with normal adiposity. In relation to vigorous activity, girls showed 198 minutes/week less when compa- red to boys. The association of factors investigated in this study with the practice of physical activity in adolescents varies according to the type and intensity of the activity performed.
