<head> BACKGROUND:</head>
         
<p>Food insecurity can put children at greater risk of obesity because
        of altered food choices and nonuniform consumption patterns.
</p>
      
</div>
      
<div>
         
<head> OBJECTIVE:</head>
         
<p>We examined the association between obesity and both child-level
        food insecurity and personal food insecurity in US children.
</p>
      
</div>
      
<div>
         
<head> DESIGN:</head>
         
<p>Data from 9,701 participants in the National Health and Nutrition
        Examination Survey, 2001-2010, aged 2 to 11 years were analyzed.
        Child-level food insecurity was assessed with the US Department of
        Agriculture's Food Security Survey Module based on eight
        child-specific questions. Personal food insecurity was assessed with
        five additional questions. Obesity was defined, using physical
        measurements, as body mass index (calculated as kg/m2) greater than
        or equal to the age- and sex-specific 95th percentile of the Centers
        for Disease Control and Prevention growth charts. Logistic
        regressions adjusted for sex, race/ethnic group, poverty level, and
        survey year were conducted to describe associations between obesity
        and food insecurity.
</p>
      
</div>
      
<div>
         
<head> RESULTS:</head>
         
<p>Obesity was significantly associated with personal food insecurity
        for children aged 6 to 11 years (odds ratio=1.81; 95% CI 1.33 to
        2.48), but not in children aged 2 to 5 years (odds ratio=0.88; 95%
        CI 0.51 to 1.51). Child-level food insecurity was not associated
        with obesity among 2- to 5-year-olds or 6- to 11-year-olds.
</p>
      
</div>
      
<div>
         
<head> CONCLUSIONS:</head>
         
<p>Personal food insecurity is associated with an increased risk of
        obesity only in children aged 6 to 11 years. Personal
        food-insecurity measures may give different results than aggregate
        food-insecurity measures in children.
