Abstract:The identification of nutritional inadequacies in specific segments of the youth population can provide the basis for public health intervention. The objective of this study was to evaluate anthropometric indicators of nutritional status in a sample of adolescent schoolchildren from a region of low economic development in Brazil. The sample consisted of 1,538 subjects ranging in age from 15 to 18 years, including 1,036 girls and 502 boys. Nutritional status was assessed based on height and body mass index (BMI… Show more
Objective:
To estimate the burden of weight excess in Brazilian adolescents.
Design:
Systematic review with meta-analysis.
Setting:
We searched the literature in four databases (MEDLINE/PubMed, EMBASE, SciELO and LILACS). Studies were included if they had cross-sectional or cohort design and enrolled Brazilian adolescents. Studies based on self-reported measures were excluded. Random effect models were used to calculate prevalence estimate and its 95% confidence interval (95%CI).
Participants:
Brazilian adolescents (10 to 19 years old).
Results:
One hundred and fifty-one studies were included. Trend analyses showed a significant increase in the prevalence of excess weight in the last decades: 8.2% (95%CI:7.7-8.7) until year 2000, 18.9 (95%CI:14.7-23.2) from 2000 to 2009, and 25.1% (95%CI:23.4-26.8) in 2010 and after. A similar temporal pattern was observed in the prevalence of overweight and obesity separately. In sensitivity analyses, lower prevalence of excess weight was found in older adolescents and those defined using IOTF cutoff points. The Southeast and South regions had the highest prevalence of excess weight, overweight and obesity. No significant difference in prevalence by sex was found, except for studies before the year 2000.
Conclusions:
The prevalence of overweight and obesity in Brazilian adolescents is high and continues to rise. Public policies on an individual level and targeting modifications in the obesogenic environment are necessary.
