Abstract

In recent years, the consumption of ultraprocessed foods in schoolchildren has increased and this has been linked to an increase in the prevalence of childhood obesity. Objective: To calculate the size of the effect of a nutritional intervention on food consumption in basic education schoolchildren in Reynosa, Tamaulipas, Mexico. Materials and methods: Longitudinal study, with a sample of 309 schoolchildren from 12 public elementary schools; two groups were formed: intervention (IG) and control (CG) with a follow-up of one year. Measurements of weight, height and waist circumference were made. To evaluate the foods included in school lunch, a food registry was used before and after the intervention and they were characterized as recommended and not recommended. The effect size (ES) was calculated using the Hedges’g statistic. Results: At the end of the study in both groups, water consumption increased, however the ES was big in the IG (ES=0.84); while in the CG it was moderate (ES=0.50). In the IG, a small reduction in the consumption of processed meats was observed (p=0.004; ES=0.28), sweet cereals (p=0.001; ES=0.36) and sweetened nondairy beverages decreased (p=0.001; ES=0.49); while the CG showed a small increase in the consumption of fast food and Mexican appetizers (p=0.001; ES=0.46). Conclusions: In the IG showed a TE small decrease in consumption of processed meats, sweet cereals, and sweetened non-dairy beverages. It is necessary to design strategies that promote the consumption of recommended foods.
营养干预对墨西哥塔毛利帕斯雷诺萨基础教育学童食物消费的影响
近年来,学童中超加工食品的消费量有所增加,这与儿童肥胖患病率的增加有关。目的:计算营养干预对墨西哥塔毛利帕斯州雷诺萨市基础教育学童食物消费的影响程度。材料与方法:纵向研究,12所公立小学309名在校生;分为干预组(IG)和对照组(CG),随访1年。测量了体重、身高和腰围。为了评估学校午餐中包括的食物,在干预前后使用了食物登记,并将它们分为推荐和不推荐。效应量(ES)采用Hedges 'g统计量计算。结果:在研究结束时,两组患者的耗水量均有所增加,但IG期ES较大(ES=0.84);而CG组为中度(ES=0.50)。在IG中,观察到加工肉类消费量的小幅减少(p=0.004;ES=0.28),甜谷物(p=0.001;ES=0.36),加糖非乳制品饮料减少(p=0.001;ES = 0.49);而CG显示快餐和墨西哥开胃菜的消费量略有增加(p=0.001;ES = 0.46)。结论:在IG中显示,加工肉类、甜谷物和加糖非乳制品饮料的消费量有小幅下降。有必要设计促进推荐食品消费的策略。
