在美国人的饮食中，超加工食品提供了58%的能量摄入和%的添加糖。然而，超加工食品和超重之间的联系还没有在美国样本中进行调查。因此，目前的调查旨在调查具有全国代表性的美国成年人样本中超加工食品与超重之间的联系。我们对参加2005年至2014年全国健康与营养检查调查的15977名成年人(20-岁)的人体测量和饮食数据进行了横断面分析。膳食数据通过24小时回忆法收集。测量身高、体重和腰围。根据NOVA的分类，食品被归类为超加工/非超加工。采用多元线性回归和Logistic回归分析超加工食品摄入量(%能量)与BMI、WC、BMI>；=25 kg/m(2)、BMI>；=30 kg/m(2)和腹型肥胖(男性：WC>；=102 cm，女性：WC>；=88 cm)之间的关系。BMI和Gt；=25 kg/m(2)、BMI和Gt；=30 kg/m(2)和腹型肥胖的患病率分别为69.2%、36.1%和53.0%。从超加工食品中摄取总能量的36.5%与体重指数增加1.61单位(95%可信区间1.11，2.10)、腰围增加4.07厘米(95%可信区间2.94，5.19)和体重指数=25 kg/m(2)、体重指数=30 kg/m(2)和腹型肥胖的风险分别高48、53和62%(OR 1.48；95%CI 1.25、1.76；OR 1.53；95%CI分别为1.29、1.81；OR为1.62；95%CI分别为1.39、1.89；P均为0.001)。女性在体重指数(F4，79=4.89，P=0.002)、腰围(F-4，F-79=3.71，P=0.008)和体重指数(BMI>；)=25 kg/m(2)(F-4，F-79=5.35，P<；0.001)方面存在显著交互作用。作为对美国人群的第一项研究，我们的发现支持了超加工食品的高消费量与超重相关，而且这种关联在女性中更为明显。
Ultra-processed foods provide 58% of energy intake and 89% of added sugars in the American diet. Nevertheless, the association between ultra-processed foods and excess weight has not been investigated in a US sample. The present investigation therefore aims to examine the association between ultra-processed foods and excess weight in a nationally representative sample of US adults. We performed a cross-sectional analysis of anthropometric and dietary data from 15 977 adults (20-64 years) participating in the National Health and Nutrition Examination Survey 2005-2014. Dietary data were collected by 24-h recall. Height, weight and waist circumference (WC) were measured. Foods were classified as ultraprocessed/non-ultra-processed according to the NOVA classification. Multivariable linear and logistic regression was used to evaluate the association between ultra-processed food consumption (% energy) and BMI, WC and odds of BMI >= 25 kg/m(2), BMI >= 30 kg/m(2) and abdominal obesity (men: WC >= 102 cm, women: WC >= 88cm). Prevalence of BMI >= 25 kg/m(2), BMI >= 30 kg/m(2) and abdominal obesity was 69.2, 36.1 and 53.0%, respectively. Consuming >= 74.2 v. >= 36.5% of total energy from ultra-processed foods was associated with 1.61 units higher BMI (95% CI 1.11, 2.10), 4.07 cm greater WC (95 % CI 2.94, 5.19) and 48, 53 and 62% higher odds of BMI >= 25 kg/m(2), BMI >= 30 kg/m(2) and abdominal obesity, respectively (OR 1.48; 95% CI 1.25, 1.76; OR 1.53; 95% CI 1.29, 1.81; OR 1.62; 95% CI 1.39, 1.89, respectively; Pfor trend < 0.001 for all). A significant interaction between being female and ultra-processed food consumption was found for BMI (F4,79 = 4.89, P = 0.002), WC (F-4,F-79 = 3.71, P = 0.008) and BMI >= 25 kg/m(2) (F-4,F-79 = 5.35, P < 0.001). As the first study in a US population, our findings support that higher consumption of ultra-processed food is associated with excess weight, and that the association is more pronounced among women.
