Abstract
Aim: We investigated the demographic, anthropometric, clinical, biochemical and behavioural factors associated with children and adolescents who missed breakfast.Methods: This 2012 cross-sectional study was carried out in the city of Juiz de Fora, Brazil, with a sample of 684 students: 191 children aged 7-9 and 493 adolescents aged 10-14. Data on demographic, physical activity and breakfast consumption were based on a 24-hour recall record and a three-day dietary record. Weight, height, body fat, waist circumference and blood pressure were also measured. Finally, samples were collected for analysis of blood total cholesterol, low-density and high-density lipoproteins, triglycerides and glucose. The statistics are presented as prevalence ratios (PR) with 95% confidence (95% CI) intervals.Results: Missing breakfast was more common among adolescents than children (30% versus 22%) and among girls of all ages than among boys (33% versus 22%). It was also associated with children, but not adolescents, with increased levels of diastolic blood pressure (PR 5.6, 95% CI 1.8-17.4), total cholesterol (PR 1.5, 95% CI 1.2-1.9) and low-density lipoprotein (PR 2.1, 95% CI 1.5-2.9).Conclusion: Missing breakfast was more common among adolescents and females and associated with increased levels of diastolic blood pressure, total cholesterol and low-density lipoprotein in children.
