Background and objectives: To quantify whole grain intake in pregnant women in Singapore in order to provide the first detailed analysis of whole grain intake in an Asian country and in pregnant women.
Methods and study design: Analysis of 24-h diet recalls in a cross-sectional cohort study and analysis of a biomarker of whole grain intake (plasma alkylresorcinols) in a subset of subjects. The Growing Up in Singapore Towards healthy Outcomes-mother offspring cohort study based in Singapore. 998 pregnant mothers with complete 24-h recalls taken during their 26-28th week of gestation. Plasma samples from a randomly select subset of 100 subjects were analysed for plasma alkylresorcinols.
Results: Median (IQR) whole grain intake for the cohort and the 30% who reported eating whole grains were 0 (IQR 0, 9) and 23.6 (IQR 14.6, 44.2) g/day respectively. Plasma alkylresorcinol concentrations were very low [median (IQR)=9 (3, 15) nmol/L], suggesting low intake of whole grain wheat in this population. Plasma alkylresorcinols were correlated with whole grain wheat intake (Spearman's r=0.35; p<0.01).
Conclusions: Whole grain intake among pregnant mothers in Singapore was well below the 2-3 (60-95 g) servings of whole grains per day recommended by the Singapore Health Promotion Board. Efforts to increase whole grain intake should be supported to encourage people to choose whole grains over refined grains in their diet.
背景与目的：为了给亚洲国家提供一个详细的孕妇全谷物摄入量的分析报告,本 文定量分析了新加坡孕妇全谷物的摄入量。方法与研究设计：在一个横断面队 列研究中分析24 小时膳食回顾，并分析一个亚组受试者的全谷物摄入量标志 物（血浆烷基间苯二酚）。在新加坡长大的母亲子代健康结局队列研究。998 名孕妇在她们怀孕26-28 周时完成24 小时膳食回顾。血浆样本采自随机选择的 100 个研究对象组成的亚组，用来分析血浆烷基间苯二酚 。结果：队列中全部 志愿者和队列中30%报告了摄入全谷物的人群其全谷物摄入的中位数分别为0 （0，9）和23.6（14.6，44.2）克/天。血浆烷基间苯二酚浓度非常低（中位数 =9 (3，15) nmol/L），提示该人群全谷物摄入量低。血浆烷基间苯二酚与全谷 物摄入量相关（Spearman's r=0.35； p<0.01）。结论：新加坡孕妇全谷物摄入 量远远低于新加坡健康促进局推荐的每天摄入全谷物2-3 份（60-95）克。应该 鼓励人们在他们的饮食中选择全谷物而不是精制谷物，以增加全谷物的摄入 量。.
