Food insecurity affects 13 million children in the United States. Body dissatisfaction is also prevalent, affecting up to 46% of children. Both food insecurity and body dissatisfaction are associated with poor health outcomes, and both are associated with body weight and racial/ethnic disparities. The association between food insecurity and body dissatisfaction among children has not been examined.
The purpose of this study was twofold: to examine, in a sample of children in grades 4 through 8, the relationship of child food insecurity with body dissatisfaction and to gain an understanding of the interactive roles of body mass index (BMI), race/ethnicity, and sex in the relationship between food insecurity and body dissatisfaction.
This was a cross-sectional study.
PARTICIPANTS/SETTING: This study examined data obtained from 14,768 children in grades 4 through 8 from 54 public schools in California between 2014 and 2016.
The primary outcome of interest was body dissatisfaction (five items converted to a binary indicator), and the exposure of interest was child-reported food insecurity (three items converted to a binary indicator). Subsets of validated questionnaires were used to assess body dissatisfaction and food insecurity.
Data were analyzed using multivariable logistic regression, and effect modification was examined by BMI category (underweight, normal, overweight, obese), race/ethnicity, and sex.
In this large and diverse sample, after adjusting for cofounders, children experiencing food insecurity, in all BMI categories and from all racial/ethnic backgrounds, had higher odds of body dissatisfaction than their food-secure counterparts. The strength of the relationship differed by BMI and race/ethnicity, with the strongest associations observed for African-American children (odds ratio=2.32; P<0.001) and children with a normal children (odds ratio=1.76; P<0.001).
Experiencing food insecurity was associated with greater body dissatisfaction, with the magnitude of the association modified by BMI and race/ethnicity.
在美国,有 1300 万儿童面临食物无保障问题。身体不满的现象也很普遍,影响了多达 46%的儿童。食物无保障和身体不满都与健康状况不佳有关,两者都与体重和种族/民族差异有关。儿童中食物无保障与身体不满之间的关联尚未得到检验。
本研究的目的有两个:一是在 4 至 8 年级的儿童样本中,检验儿童食物无保障与身体不满之间的关系;二是了解身体质量指数(BMI)、种族/民族和性别在食物无保障与身体不满之间的关系中的相互作用。
这是一项横断面研究。
参与者/设置:本研究检查了 2014 年至 2016 年期间加利福尼亚州 54 所公立学校的 14768 名 4 至 8 年级儿童的数据。
主要观察结果是身体不满(5 项转换为二项指标),感兴趣的暴露是儿童报告的食物无保障(3 项转换为二项指标)。使用经过验证的问卷子集来评估身体不满和食物无保障。
使用多变量逻辑回归分析数据,通过 BMI 类别(体重不足、正常、超重、肥胖)、种族/民族和性别来检查效应修饰。
在这个大型且多样化的样本中,在校正混杂因素后,经历食物无保障的儿童,在所有 BMI 类别和所有种族/民族背景下,比食物有保障的儿童更有可能感到身体不满。这种关系的强度因 BMI 和种族/民族而异,与非裔美国儿童(比值比=2.32;P<0.001)和 BMI 正常的儿童(比值比=1.76;P<0.001)的关联最强。
经历食物无保障与更大的身体不满有关,这种关联的大小受到 BMI 和种族/民族的影响。
