This study examined the relation between household food security status and current measured weight and change in self-reported weight over 12 mo using data from the 1999-2000 and 2001-2002 National Health and Nutrition Examination Surveys. Current measured BMI categories were as follows: underweight (<18.5 kg/m(2)), overweight (> or =25 kg/m(2)), and obese (> or =30 kg/m(2)). Change in self-reported weight used 2 cut-off points, i.e., a gain/loss of at least 2.27 kg (5 lb) and at least 4.54 kg (10 lb). Household food security categories were as follows: fully secure, marginally secure, insecure without hunger, and insecure with hunger. Multivariate analyses were adjusted for race/ethnicity, household income, education level, and current health status. Compared with women in households that were fully food secure, women in households that were marginally food secure [odds ratio (OR) 1.58] and food insecure without hunger (OR 1.76) were significantly more likely to be obese. Compared with women in households that were fully food secure, those in households that were marginally food secure were significantly more likely to gain at least 4.54 kg (OR 1.68). Compared with men in households that were fully food secure, men in households that were marginally food secure were more likely to be obese and to gain at least 4.54 kg, but these effects were smaller in magnitude than those for women and insignificant in some specifications. This study corroborates previous cross-sectional associations between intermediate levels of food insecurity and obesity for women, and it finds an association between intermediate levels of food insecurity and 12-mo weight gain for women.
本研究利用1999 - 2000年和2001 - 2002年国家健康与营养检查调查的数据，考察了家庭粮食安全状况与当前测量体重以及12个月内自我报告体重变化之间的关系。当前测量的体重指数（BMI）类别如下：体重过轻（<18.5千克/平方米）、超重（≥25千克/平方米）和肥胖（≥30千克/平方米）。自我报告体重的变化采用两个临界点，即体重增加/减少至少2.27千克（5磅）和至少4.54千克（10磅）。家庭粮食安全类别如下：完全安全、边际安全、无饥饿的不安全和有饥饿的不安全。多变量分析针对种族/族裔、家庭收入、教育水平和当前健康状况进行了调整。与粮食完全安全家庭中的女性相比，粮食边际安全家庭中的女性[优势比（OR）为1.58]和无饥饿的粮食不安全家庭中的女性（OR为1.76）肥胖的可能性显著更高。与粮食完全安全家庭中的女性相比，粮食边际安全家庭中的女性体重增加至少4.54千克的可能性显著更高（OR为1.68）。与粮食完全安全家庭中的男性相比，粮食边际安全家庭中的男性更有可能肥胖且体重增加至少4.54千克，但这些影响的程度小于女性，并且在某些规格中不显著。本研究证实了先前关于粮食不安全中间水平与女性肥胖之间的横断面关联，并且发现了粮食不安全中间水平与女性12个月体重增加之间的关联。
