CASTILHO, Silvia Diez; NUCCI, Luciana Bertoldi; HANSEN, Lucca Ortolan  e  ASSUINO, Samanta Ramos. Prevalence of weight excess according to age group in students from Campinas, SP, Brazil. Rev. paul. pediatr. [online]. 2014, vol.32, n.2, pp.200-206. ISSN 1984-0462.  https://doi.org/10.1590/0103-0582201432214713.

OBJECTIVE:

To evaluate the prevalence of weight excess in children and adolescents attending public and private schools of Campinas, Southeast Brazil, according to age group.

METHODS:

Cross-sectional study that enrolled 3,130 students from 2010 to 2012. The weight and the height were measured and the body mass index (BMI) was calculated. The students were classified by BMI Z-score/age curves of the World Health Organization (WHO)-2007 (thinness, normal weight, overweight and obesity) and by age group (7-10, 11-14 and 15-18 years). Multinomial logistic regression analysis was applied to verify variables associated to overweight and obesity.

RESULTS:

Among the 3,130 students, 53.7% attended public schools and 53.4% were girls. The prevalence of weight excess (overweight or obesity) was higher in private schools (37.3%) than in public ones (32.9%) and among males (37.5%), compared to females (32.7%; p<0.05). The chance of having weight excess in children aged 7-10 years was more than twice of those over 15 years old (OR 2.4; 95%CI 2.0-3.0) and it was 60% higher for the group with 11-14 years old (OR 1.6; 95%CI 1.3-2.0). The chance of being obese was three times higher in 7-10 years old children than in the adolescents with 15-18 years old (OR 4.4; 95%CI 3.3-6.4) and 130% higher than the group with 11-14 years old (OR 2.3; 95%CI 1.6-3.2).

CONCLUSIONS:

The prevalence of weight excess in Campinas keeps increasing at an alarming rate, especially in the younger age group.
