This study aimed to identify meal and snack patterns in Brazilian schoolchildren and assess their stability over 3 years. This is a repeated cross-sectional study carried out in 2013, 2014 and 2015 with 6353 schoolchildren aged 7-12 years from public schools in Florianópolis, Brazil. Previous-day food consumption data for six pre-defined meals (breakfast, mid-morning snack, lunch, mid-afternoon snack, dinner and evening snack) were collected using the validated Web-CAAFE (Food Consumption and Physical Activity of Schoolchildren) questionnaire. Latent class analysis was performed to derive meal and snack patterns.The stability of patterns was analysed using multinomial logistic regression, and the probability of belonging to a meal pattern was calculated for each year. Three patterns were identified for breakfast and four patterns for a mid-morning snack, lunch, mid-afternoon snack, dinner and evening snack. Most meal and snack patterns were stable over the 3-year evaluation period. In the total sample, for a mid-afternoon snack, there was an increase in the probability of the children belonging to the 'Fruits and porridge' pattern (14.5%, 95% CI 12%-17% in 2015 vs. 9.2%, 95% CI 6.8%-11.7% in 2013) and a reduction in the 'Ultra-processed'
Omission of breakfast starts at school age and can be explained as a reflection of the independent behaviour acquired in this phase of life. Breakfast has been investigated for its association with healthier diet quality, but few studies have investigated this relationship in schoolchildren aged 7 to 13 years. The objective of this study was to assess breakfast consumption in schoolchildren aged 7 to 13 years and to examine associations with dietary patterns (DPs). It was a cross‐sectional study carried out in 2017 with 1069 students in Florianopolis, southern Brazil. Previous‐day food consumption, physical activity and screen activities were self‐reported. Factor analysis was used to identify DPs. Associations between breakfast consumption and overall DPs were evaluated using multivariate linear regression. Breakfast consumption was reported by 85% of the children, with the highest proportion observed among students on the afternoon school shift. Five DPs were identified explaining 41% of the total variance in daily food consumption: Ultra‐processed, Mixed, Traditional Brazilian Lunch, Healthy + Sweets and Traditional Brazilian Breakfast. Breakfast consumption was directly associated with a Traditional Brazilian Breakfast DP (β = 0.335; 95% CI = 0.227, 0.442), a Mixed DP (β = 0.241; 95% CI = 0.160, 0.323), and a Healthy + Sweets DP (β = 0.160; 95% CI = 0.061, 0.260), and inversely associated with an Ultra‐processed DP (β = −0.116; 95% CI = −0.207, −0.026). Breakfast consumption was associated with overall DPs, suggesting the importance of eating this meal by schoolchildren. We emphasise the relevance of offering a healthy breakfast at public schools for students who do not take this meal at home, contributing to health promotion.
