Ultraprocessed food (UPF) intake is associated with BMI, but effects on regional adipose depots or related to minimally processed food (MPF) intake are unknown.
Data included 12,297 adults in the National Health and Nutrition Examination Survey (NHANES), 2011 to 2016. This study analyzed associations between usual percentage of kilocalories from UPFs and MPFs and three adiposity indicators: supine sagittal abdominal diameter to height ratio (SADHtR, estimates visceral adiposity); waist circumference to height ratio (WHtR, estimates abdominal adiposity); and BMI, using linear and multinomial logistic regression.
Standardized β coefficients per 10% increase in UPF intake were 0.0926, 0.0846, and 0.0791 for SADHtR, WHtR, and BMI, respectively (all p < 0.001; p > 0.26 for pairwise differences). For MPF intake, the β coefficients were -0.0901, -0.0806, and -0.0688 (all p < 0.001; p > 0.18 pairwise). Adjusted odds ratios (95% CI) for adiposity tertile 3 versus tertile 1 (comparing UPF intake quartiles 2, 3, and 4 to quartile 1) were 1.33 (1.22-1.45), 1.67 (1.43-1.95), and 2.24 (1.76-2.86), respectively, for SADHtR; 1.31 (1.19-1.44), 1.62 (1.37-1.91), and 2.13 (1.63-2.78), respectively, for WHtR; and 1.27 (1.16-1.39), 1.53 (1.31-1.79), and 1.96 (1.53-2.51), respectively, for BMI. MPF intake showed inverse associations with similar trends in association strength.
Among US adults, abdominal and visceral adiposity indictors were positively associated with UPFs and inversely associated with MPFs.
超加工食品（UPF）的摄入与 BMI 有关，但与最小加工食品（MPF）摄入相关的局部脂肪沉积或影响尚不清楚。
本研究纳入了 2011 年至 2016 年全国健康和营养调查（NHANES）中的 12297 名成年人的数据。本研究分析了 UPF 和 MPF 的常用卡路里百分比与三种肥胖指标之间的关联：仰卧矢状腹部直径与身高比（SADHtR，估计内脏脂肪）；腰围与身高比（WHtR，估计腹部脂肪）和 BMI，使用线性和多项逻辑回归。
UPF 摄入量每增加 10%，SADHtR、WHtR 和 BMI 的标准化 β 系数分别为 0.0926、0.0846 和 0.0791（均 P<0.001；两两比较 P>0.26）。对于 MPF 摄入量，β系数分别为-0.0901、-0.0806 和-0.0688（均 P<0.001；两两比较 P>0.18）。与第 1 三分位相比，第 3 三分位的肥胖三分位数（比较 UPF 摄入量四分位 2、3 和 4 与四分位 1）的比值比（95%CI）分别为 1.33（1.22-1.45）、1.67（1.43-1.95）和 2.24（1.76-2.86），用于 SADHtR；分别为 1.31（1.19-1.44）、1.62（1.37-1.91）和 2.13（1.63-2.78），用于 WHtR；和分别为 1.27（1.16-1.39）、1.53（1.31-1.79）和 1.96（1.53-2.51），用于 BMI。MPF 摄入与具有相似关联强度的趋势呈负相关。
在美国成年人中，腹部和内脏肥胖指标与 UPF 呈正相关，与 MPF 呈负相关。
