Prevalence of abdominal obesity in adolescents: association between sociodemographic factors and lifestyle

Abstract

Objective:To estimate the prevalence of abdominal obesity and verify the association with sociodemographic factors (gender, school shift, ethnicity, age, maternal education and economic status) and lifestyle (alcohol consumption, sleep, soft drink consumption, level of physical activity and sedentary behavior) in adolescents in Southern Brazil.Methods:This was a cross-sectional epidemiological study of 930 adolescents (490 girls) aged 14–19 years, living in the city of São José, SC, Brazil. A self-administered questionnaire was used to collect sociodemographic and lifestyle data. Abdominal obesity was measured through the waist circumference and analyzed according to gender and age. Descriptive statistics (absolute and relative frequency, mean and standard deviation) and binary logistic regression, expressed as Odds Ratios (OR) and 95% confidence interval (95%CI) were employed, with p<0.05 being considered statistically significant; the SPSS 17.0 software was used for the statistical analyses.Results:The prevalence of abdominal obesity was 10.6% for the total sample (10.5% male, 10.8% female). Adolescents that watched television daily for two or more hours (OR=2.11, 95%CI 1.08–4.13) had a higher chance of having abdominal obesity and adolescents whose mothers had fewer than eight years of schooling (OR=0.56; 95%CI from 0.35 to 0.91) had a lower chance of having abdominal obesity.Conclusions:Approximately one in 10 adolescents had abdominal obesity; the associated factors were maternal schooling (≥8 years) and television screen time (≥2h/day).

Prevalence of general and abdominal obesity among adolescents attending independent schools in Qatar

“…Similar findings have been reported by other studies conducted in different countries (KSA, Brazil., Spain, Greece and Germany). Compared to other studies, AO based on WC using the cut-off proposed by Taylor et al, was higher in Qatar than that reported in Spain (Schroder et al , 2014) and in Brazil (Castro et al , 2016; Calvalcanti et al , 2010). National representatives studies using 90th percentile cut-off for age and sex reported low rates of AO compared to the present study (Tzotzas et al , 2008; Schwandt et al , 2010; Jackson et al , 2010).…”

“…Adolescents and young people have presented habits and patterns related to unhealthy lifestyle such as sedentarism, intake of fats, sugars and salt, consumption of tobacco, alcohol and other drugs (3)(4)(5) , with an impact on their health and quality of life.

Adolescent obesity: An emerging public health crisis in an urban city in South-South Nigeria

“…The prevalence of Central obesity obtained from this study is high, and higher than the 10.6% and 8.4% reported by Castro et al and Park et al, in Brazilian and Korean adolescents respectively. 31,32 The difference in prevalence may be due to the sample size used in this study compared to these other two mentioned. However, the prevalence of central obesity is much lower than the 24.5% reported by Senbanjo and Oshikoya amongst adolescents in Abeokuta.…”
