Abstract

Objective: To explore the differences in ultra-processed food (UPF) consumption across different socioeconomic status (SES) levels.

Methods: Data on UPF consumption (grams/day) were derived from the 2017-2018 National Health and Nutrition Examination Survey. The analysis controlled for age, marital status, race, and sex. A restricted cubic spline (RCS) model was applied to examine the nonlinear response curve.

Results: UPF consumption increased with higher poverty income ratio (PIR), the ratio of household income to the established poverty line. Compared to the low PIR group, the medium group showed a non-significant increase (β = 34.23[95%CI: -28.81, 97.28], p = 0.287), while the high group exhibited a significant increase (β = 115.15[95%CI: 43.53, 186.76], p = 0.002). A linear positive correlation was observed in RCS analysis (p-nonlinear = 0.166, p-overall < 0.001).

Conclusions: The study highlights that higher SES is associated with greater consumption of UPF in the US. The findings suggest that policy interventions should take SES into consideration.

较高的社会经济地位与较高的超加工食品摄入量有关：一项横断面分析。

目的探讨不同社会经济地位（SES）水平的超加工食品（UPF）消费差异：UPF消费量（克/天）数据来自2017-2018年全国健康与营养调查。分析控制了年龄、婚姻状况、种族和性别。应用受限立方样条曲线（RCS）模型研究非线性响应曲线：UPF 消费量随着贫困收入比（PIR）（即家庭收入与既定贫困线的比率）的提高而增加。与低贫困收入比组相比，中贫困收入比组的增长不显著（β = 34.23[95%CI: -28.81, 97.28]，p = 0.287），而高贫困收入比组的增长显著（β = 115.15[95%CI: 43.53, 186.76]，p = 0.002）。在 RCS 分析中观察到线性正相关（p-nonlinear = 0.166，p-overall < 0.001）：研究强调，在美国，较高的社会经济地位与较高的 UPF 消费量相关。研究结果表明，政策干预措施应考虑到社会经济地位。
