Abstract：
Dietary patterns (DPs), usually established in adolescents, are important modifiable risk factors in the etiology of malnutrition and chronic diseases. This study aimed to identify DPs of adolescents and examine their associations with growth, sociodemographic, and lifestyle characteristics. A nationally representative, school-based, cross-sectional study was conducted in Israeli adolescents aged 11-18 years during 2015-2016. A self-administered survey queried sociodemographics, health behaviors, and diet. Weight and height were measured, and WHO height z-scores and BMI cutoffs were calculated. Food frequency questionnaire data were analyzed using principal components analysis (PCA) to identify DPs. Associations between growth, lifestyle, and sociodemographic characteristics and DPs were modeled using multivariable logistic regressions. A total of 3902 adolescents (46% males, mean age 15.2 ± 1.6 years) completed the survey. PCA identified five DPs, accounting for 38.3% of the total variance. The first two prominent DPs were the \'plant-based food\' DP, which was associated with the female sex, higher socioeconomic status, overweight/obesity, and healthy lifestyle and the \'junk food\' DP, which was associated with lower SES, unhealthy lifestyle, and lower height z-scores. Our results elucidate major DPs that strongly correlate with lifestyle risk behaviors and suboptimal growth among adolescents. Implementing screening for DPs should be further examined to identify higher risk health factors among youth.
摘要：
饮食模式（DP），通常在青少年中建立，是营养不良和慢性病病因中重要的可改变的危险因素。这项研究旨在识别青少年的DP，并检查他们与成长的关系，社会人口统计学，和生活方式特征。全国代表，校本,我们在2015-2016年期间对11-18岁的以色列青少年进行了横断面研究.一项自我管理的调查查询了社会人口统计，健康行为,和饮食。测量体重和身高，并计算了WHO身高z评分和BMI截止值。使用主成分分析（PCA）分析食物频率问卷数据以识别DPs。增长之间的关联，生活方式,使用多变量逻辑回归对社会人口统计学特征和DP进行建模。共有3902名青少年(46%为男性，平均年龄15.2±1.6岁）完成了调查。PCA确定了五个DP，占总方差的38.3%。前两个著名的DP是“植物性食品”DP，这与女性有关，更高的社会经济地位，超重/肥胖，健康的生活方式和“垃圾食品”DP，这与较低的SES有关，不健康的生活方式,和较低的身高z分数。我们的结果阐明了与生活方式风险行为和青少年次优生长密切相关的主要DP。应进一步检查对移民进行筛查，以确定青年中风险较高的健康因素。
