Meal and snack patterns of 7-13-year-old schoolchildren in southern Brazil.

ABSTRACT:

Objective

The aim of the current study was to identify and describe the meal and snack patterns (breakfast, mid-morning snack, lunch, mid-afternoon snack, dinner and evening snack) of public schoolchildren.

Design

Cross-sectional study. Information on the previous day's food intake was obtained through the Web-CAAFE (Food Intake and Physical Activity of Schoolchildren), an interactive questionnaire, which divides daily food consumption into three meals (breakfast, lunch and dinner) and three snacks (mid-morning, mid-afternoon and evening). Each meal contains thirty-one food items and the schoolchildren clicked on the food items consumed in each meal. Factor analysis was used to identify meal and snack patterns. The descriptions of the dietary patterns (DP) were based on food items with factor loads ≥ 0·30 that were considered representative of each DP.

Setting

Schoolchildren, Florianopolis, Brazil.

Participants

Children (n 1074) aged 7-13 years.

Results

Lunch was the most consumed meal (96·0 %), followed by dinner (86·4 %), breakfast (85·3 %) and mid-afternoon snack (81·7 %). Four DP were identified for breakfast, mid-morning snack, lunch, dinner and evening snack, and three for mid-afternoon snack. Breakfast, lunch and dinner patterns included traditional Brazilian foods. DP consisting of fast foods and sugary beverages were also observed, mainly for the evening snack.

Conclusions

The results of the current study provide important information regarding the meal and snack patterns of schoolchildren to guide the development of nutrition interventions in public health.

Project description:BackgroundLinkages between snack patterns, diet, and obesity in adolescents likely depend on the consumption of main meals, how often snacks are prepared away from home, and whether energy-dense, nutrient-poor snack foods and sugary drinks are frequently consumed. Nutrition-based interventions need to be informed by an understanding of how secular changes in the contribution of snacks to dietary intake may be related to changes in meal frequency as well as how these trends differ by sociodemographic characteristics.ObjectivesTo examine secular trends from 1999 to 2010 in meal and snack patterns among adolescents.DesignA repeated cross-sectional design was used.Participants/settingParticipants from Minneapolis/St Paul, MN, secondary schools completed classroom-administered surveys and food frequency questionnaires in 1999 (n=2,598) and 2010 (n=2,540).Main outcome measuresWeekly meal frequencies; number of snacks consumed on school and vacation/weekend days; frequent consumption of snacks prepared away from home (≥3 times/week); and daily servings of energy-dense, nutrient-poor food/drinks that are commonly consumed at snack occasions.Statistical analyses performedTrends from 1999 to 2010 were examined using inverse probability weighting to control for differences in sociodemographic characteristics in the two samples.ResultsMean frequencies of breakfast and lunch increased modestly in the overall population (both P values <0.001), and there were decreases in the number of snacks consumed on schools days (P<0.001) and vacation/weekend days (P=0.003). Although there was no change in the proportion of adolescents who reported frequent consumption of snacks prepared away from home, there was a secular decrease in energy-dense, nutrient-poor food/drink consumption (P<0.001). Sociodemographic differences in the identified trends were evident.ConclusionsThe observed pattern of sociodemographic characteristic differences in meal and snack trends among adolescents suggests the need for targeted efforts to ensure public health messages reach low-income and ethnic/racial minority population subgroups most vulnerable to poor nutrition and the development of obesity.

Project description:This experiment examined changes in body sway after Wingate test (WAnT) in 19 adolescents practicing alpine skiing, subjected to the same type of training load for 4-5 years (10 girls and nine boys). The postural examinations were performed with eyes open (EO), eyes closed (EC), and sway reverenced vision (SRV) in the medial-lateral (ML) and anterior-posterior (AP) planes. The displacement of center of foot pressure (CoP), range of sway (RS), mean sway velocity (MV), way length, and surface area were measured in bipedal upright stance before and after the WAnT to assess the influence of fatigue on postural balance. There were no significant differences in WAnT parameters between girls and boys. Relative peak power (RPP), relative total work (RWtot) were (girls vs. boys) 8.89 ± 0.70 vs. 9.57 ± 1.22 W/kg, p < 0.05 and 227.91 ± 14.98 vs. 243.22 ± 30.24 W/kg, p < 0.05 respectively. The fatigue index (FI) was also on similar level in both genders; however, blood lactate concentration (BLa) was significantly higher in boys (10.35 ± 1.16 mM) than in girls (8.67 ± 1.35 mM) p = 0.007. In the EO examination, statistically significant differences between resting and fatigue conditions in the whole group and after the division into girls and boys were found. In fatigue conditions, significant gender differences were noted for measurements in the ML plane (sway path and RS) and RS in the AP plane. Comparison of the three conditions shows differences between EO vs. EC and SRV in AP plane measured parameters, and for RS in ML plane in rest condition in girls. The strong correlations between FI and CoP parameters mainly in ML plane in the whole group for all examination conditions were noted. By genders, mainly RS in ML plane strongly correlates with FI (r > 0.7). No correlation was found between BLa and CoP parameters (p > 0.06). The presented results indicate that subjecting adolescents of both genders to the same training may reduce gender differences in the postural balance ability at rest but not in fatigue conditions and that girls are significantly superior in postural balance in the ML plane than boys. It was also shown that too little or too much information may be destructive to postural balance in young adolescents.
