Although a high intake of fat, particularly SFA, is a well-known risk factor for CVD, fat intake in Japan has attracted relatively little attention from health professionals to date due to the low intake in the Japanese population. However, recent surveys have shown an increase in fat intake in younger Japanese populations. Here, we described the fat intake and dietary sources of SFA in Japanese schoolchildren. Also, we experimentally exchanged a high-SFA food with a low-SFA substitute in the data, and calculated the resulting changes in nutrient intakes.
The study was conducted nationwide under a cross-sectional design. A non-consecutive, three-day diet record was performed on two school days and a non-school day.
Fourteen elementary and thirteen junior high schools.
Elementary-school children (n 629) and junior high-school children (n 281).
Prevalence of excess fat intake was 35·4 % in boys and 45·0 % in girls. Excess SFA intake was suspected in 97·7 % of boys and 99·4 % of girls when the dietary reference intake values for adults were applied. Major dietary sources of SFA were meat (26·4 % of total SFA intake), dairy products (25·7 %) and confectioneries (11·3 %).
Since one-third to nearly one-half of our Japanese schoolchildren consumed excess fat, careful monitoring of fat intake in the Japanese population should be continued. Adoption of low-fat milk and/or lean meat in daily meals might be a suitable means of reducing fat, particularly SFA intake, in schoolchildren.
尽管高脂肪摄入,尤其是饱和脂肪酸(SFA)摄入,是心血管疾病的一个已知危险因素,但由于日本人群的脂肪摄入量较低,迄今为止,日本的健康专业人员对脂肪摄入量关注相对较少。然而,最近的调查显示,日本年轻人群的脂肪摄入量有所增加。在这里,我们描述了日本学童的脂肪摄入量和 SFA 的饮食来源。此外,我们在数据中用高 SFA 食物代替低 SFA 食物进行了实验,并计算了由此导致的营养素摄入量变化。
该研究在全国范围内采用横断面设计进行。在两个上学日和一个非上学日进行非连续的三天饮食记录。
十四所小学和十三所初中。
小学生(n=629)和初中生(n=281)。
男孩的脂肪摄入过量率为 35.4%,女孩为 45.0%。当应用成人膳食参考摄入量值时,97.7%的男孩和 99.4%的女孩怀疑摄入过多的 SFA。SFA 的主要饮食来源是肉类(占 SFA 总摄入量的 26.4%)、奶制品(25.7%)和糖果(11.3%)。
由于三分之一到近一半的日本学童摄入了过量的脂肪,因此应该继续密切监测日本人群的脂肪摄入量。在日常饮食中采用低脂肪牛奶和/或瘦肉可能是减少学童脂肪,尤其是 SFA 摄入的合适方法。
