ASSOCIATED FACTORS WITH THE ISOLATED AND SIMULTANEOUS PRESENCE OF OVERWEIGHT AND ABDOMINAL OBESITY IN ADOLESCENTS.

OBJECTIVE: To analyze the sociodemographic and lifestyle factors associated with excessive weight (EW), abdominal obesity (AO) and the simultaneous presence of EW and AO in adolescents from Southern Brazil. METHODS: Cross-sectional study with 583 adolescents (11 to 17 years old) of Criciúma, Santa Catarina, Brazil. EW was assessed by body mass index (BMI) and AO by waist circumference (WC). The independent variables analyzed were gender, age, maternal schooling, balanced diet, physical activity, cigarette use, excessive alcohol use and screen time. Binary logistic regression was used to estimate Odds Ratios (OR) and 95% confidence intervals (95%CI). RESULTS: Boys had 58% higher likelihood of having EW (OR 1.58; 95%CI 1.08-2.29; p<0.05). Younger age group (11 to 14 years) was directly associated with higher likelihood of EW (OR 6.07; 95%CI 4.05-9.11; p<0.05). Adolescents whose mothers had higher education had 75% more likelihood of having AO (OR 1.75; 95%CI 1.01-3.00; p<0.05). Higher likelihood for EW and AO (OR 1.84; 95%CI 1.01-3.34; p<0.05) was identified in younger adolescents (11 to 14 years). CONCLUSIONS: Boys and younger age (11 to 14 years) were associated with a higher likelihood of EW. Adolescents whose mothers studied nine years or more were more likely to have AO. The younger age group (11 to 14 years) was associated with greater chances for the simultaneous presence of EW and AO.

Influence of Body Dissatisfaction on the Self-Esteem of Brazilian Adolescents: A Cross-Sectional Study.

BACKGROUND: The present study investigated the influence of body dissatisfaction (BD) on the self-esteem of Brazilian adolescents. METHODS: A cross-sectional study was carried out with 1011 students at public and private schools in the city of Fortaleza, Brazil. The body shape questionnaire and the Rosenberg self-esteem scale were applied. Chi-square test, Student's t-test, Pearson's correlation, the odds ratio and binary logistic regression were used. RESULTS: The rate of low self-esteem was 33.8% in the adolescents; 27.8% of the adolescents presented some degree of BD, with severe BD in 5.8%. A significant low negative correlation was found between self-esteem and BD in all the adolescents. In the Odds Ratio analysis, it was observed that the odds of having low self-esteem increased in adolescents with BD as compared to adolescents without BD, being 3.85 times higher in females (CI 95%, 2.12-6.99), 2.83 times higher in males (CI 95%, 1.22-6.58), 5.79 times higher in adolescents attending public schools (CI 95% 2.06-16.26), and 2.96 times higher in adolescents attending private schools (CI 95%, 1.79-4.88). CONCLUSIONS: Low self-esteem affected one-third of the adolescents, both male and female. BD and education in public schools are predictor variables of low self-esteem in adolescents.

Associated factors with the isolated and simultaneous presence of overweight and abdominal obesity in adolescents / Fatores associados à presença isolada e simultânea de excesso de peso e obesidade abdominal em adolescentes

RESUMO Objetivo: Analisar os fatores sociodemográficos e do estilo de vida associados ao excesso de peso (EP), à obesidade abdominal (OA) e à presença simultânea de EP e OA em adolescentes do Sul do Brasil. Métodos: Estudo transversal de base escolar realizado com 583 adolescentes (11 a 17 anos) da cidade de Criciúma, Santa Catarina. O EP foi avaliado pelo índice de massa corpórea (IMC) e a OA, mediante perímetro da cintura (PC). As variáveis independentes analisadas foram sexo, idade, escolaridade materna, dieta balanceada, atividade física, uso de cigarro, uso de álcool em excesso e tempo de tela. Utilizou-se regressão logística binária para estimar as razões de chances (RC) e intervalos de confiança de 95% (IC95%). Resultados: Os meninos tiveram 58% de chances a mais de terem EP (RC 1,58; IC95% 1,08-2,29; p<0,05). Menor faixa etária (11 a 14 anos) foi diretamente associada a maiores chances de EP (RC 6,07; IC95% 4,05-9,11; p<0,05). Adolescentes cujas mães tinham maior escolaridade apresentaram 75% de chances a mais de terem OA (RC 1,75; IC95% 1,01-3,00; p<0,05). Maiores chances para a simultaneidade EP e OA (RC 1,84; IC95% 1,01-3,34; p<0,05) foram identificadas nos adolescentes de menor faixa etária (11 a 14 anos). Conclusões: Meninos e menor faixa etária (11 a 14 anos) estiveram associados a maiores chances para EP. Os adolescentes cujas mães estudaram nove anos ou mais apresentaram maiores chances de terem OA. Menor faixa etária (11 a 14 anos) esteve associada a maiores chances para a presença simultânea de EP e OA.
