背景：从家里摄取食物与儿童和青少年超重率高有关。然而，没有研究比较青少年在家和离家的饮食模式。目的：本文的目的是确定在家里和远离家庭的饮食模式在巴西的青少年，并评估这些模式和身体质量指数（BMI）Z-scores.Design之间的关系：从巴西全国饮食调查2008-2009年的数据进行了分析，在这个横断面研究。饮食摄入量进行了评估，完成书面的食物记录在两个noncontinuous days.Participants/setting：五千二百六十六名青少年10-19岁的生活在巴西的城市地区被列入分析。统计分析：32个食物组进行了因素分析，分层在家和离家吃饭。之间的关联的食物模式和BMI的z-分数确定使用线性回归analysis.Results：在一般情况下，平均在家里的食物摄入量大于远离家庭的食物摄入量，但远离家庭/在家里的比例大于30%的烘焙和油炸小吃，软饮料，三明治，比萨饼，甜点，低于10%的大米和豆类。三个主要的相似的饮食模式，确定了在家里和离家出走：“传统模式”，“面包和黄油模式”和“西方模式”，但是，离家出走的模式包括更全面的食物项目。结论：我们的研究结果表明，在家中消费的不健康饮食模式与BMI z得分相关，而远离家庭的食物消费与BMI z得分无关。(C)2017爱思唯尔有限公司版权所有
Background: Away-from-home food intake has been associated with high rates of overweight among children and adolescents. However, there are no studies comparing at-home and away-from-home eating patterns among adolescents. Objectives: The objective of this paper was to identify at-home and away-from-home dietary patterns among adolescents in Brazil, and to evaluate the relationship between these patterns and body mass index (BMI) z-scores.Design: Data from the Brazilian National Dietary Survey 2008-2009 were analyzed in this crosssectional study. Dietary intake was assessed by completion of written food records on two nonconsecutive days.Participants/setting: Five thousand two hundred sixty-six adolescents 10-19 years of age living in urban areas of Brazil were included in the analysis. Statistical analysis: Thirty-two food groups were examined by factor analysis, stratified by at-home and away-from-home eating. The associations between the food patterns and BMI z-scores were ascertained using linear regression analysis.Results: In general, mean at-home food intake was greater than away-from-home food intake, but the ratio of away-from-home/at-home was greater than 30% for baked and deep-fried snacks, soft drinks, sandwiches, pizza, and desserts, and was lower than 10% for rice and beans. Three main similar dietary patterns were identified both at-home and away-from-home: the "Traditional pattern", the "Bread and Butter pattern" and the "Western pattern"; however, away-from-home patterns encompassed more overall food items. Only the at-home "Western pattern" was positively associated with BMI z-scores = 0.0006; p < 0.001).Conclusion: Our results indicate that unhealthy dietary pattern consumed at home is associated to BMI z score, while away-from-home food consumption is not associated.
