Our objective was to describe, for the first time in an English-speaking Caribbean country, the contribution of ultra-processed foods (UPFs) to nutrients linked to non-communicable disease. Using a cross-sectional study design, dietary data were collected from two non-consecutive 24-h dietary recalls. Recorded food items were then classified according to their degree of processing by the NOVA system. The present study took place in Barbados (2012-13). A representative population-based sample of 364 adult Barbadians (161 males and 203 females) aged 25-64 years participated in the study. UPFs represented 40⋅5 % (838 kcal/d; 95 % CI 791, 885) of mean energy intake. Sugar-sweetened beverages made the largest contribution to energy within the UPF category. Younger persons (25-44 years) consumed a significantly higher proportion of calories from UPF (NOVA group 4) compared with older persons (45-64 years). The mean energy shares of UPF ranged from 22⋅0 to 58⋅9 % for those in the lowest tertile to highest tertile. Within each tertile, the energy contribution was significantly higher in the younger age group (25-44 years) compared with the older (45-64 years). One-quarter of persons consume ≥50 % of their daily calories from UPF, this being significantly higher in younger persons. The ultra-processed diet fraction contained about six times the mean of free sugars and about 0⋅8 times the dietary fibre of the non-ultra-processed fraction (NOVA groups 1-3). Targeted interventions to decrease the consumption of UPF especially in younger persons is thus of high priority to improve the diet quality of Barbadians.
我们的目标是首次在一个讲英语的加勒比国家描述超加工食品(UPF)对与非传染性疾病相关营养素的贡献。本研究采用横断面研究设计,通过两次非连续的 24 小时膳食回忆收集膳食数据。记录的食物项目随后根据 NOVA 系统的加工程度进行分类。本研究在巴巴多斯进行(2012-13 年)。25-64 岁的 364 名成年巴巴多斯人(161 名男性和 203 名女性)参加了该研究,该人群具有代表性。UPF 占平均能量摄入的 40.5%(838 千卡/天;95%CI 791,885)。含糖饮料在 UPF 类别中对能量的贡献最大。与老年人(45-64 岁)相比,年轻人(25-44 岁)从 UPF(NOVA 组 4)中摄入的卡路里比例明显更高。在能量摄入最低和最高三分位数的人群中,UPF 的平均能量份额从 22.0%到 58.9%不等。在每个三分位数内,年轻组(25-44 岁)的能量贡献明显高于老年组(45-64 岁)。四分之一的人每天摄入的卡路里有 50%以上来自 UPF,而年轻人的这一比例明显更高。超加工饮食部分的游离糖含量平均是未超加工饮食部分(NOVA 组 1-3)的六倍,膳食纤维含量则低 0.8 倍。因此,特别针对年轻人减少 UPF 摄入量的干预措施对于提高巴巴多斯人饮食质量具有高度优先性。
