All bariatric surgical procedures may compromise the nutritional status of patients, but nutritional deficiencies vary by region and culture. However, there are no preoperative nutritional guidelines for bariatric patients in East Asia. Here, we aimed to evaluate the preoperative nutritional status of East Asian bariatric surgical patients.
We performed a retrospective cohort study of 215 consecutive patients who underwent bariatric surgery between January and December 2019 at a single tertiary institution in Korea. Medical background evaluation, anthropometric measurements, and laboratory tests were performed before surgery.
Vitamin D deficiency was identified in 80.0% of participants and 13.8% had insufficiency. The prevalence of vitamin D deficiency or insufficiency and the mean vitamin D concentration did not significantly differ between the sexes. Vitamin B1 (thiamine) deficiency was the second most common deficiency (18.3%), followed by folate (14.2%), iron (11.8%), and zinc (7.6%) deficiencies. The prevalence of anemia did not significantly differ between the sexes (1.3% in men vs. 7.4% in women, p=0.10), but the prevalence of iron deficiency was significantly higher in women (1.3% vs. 17.9%, p<0.001). The prevalences of copper (2.3%) and selenium (3.2%) deficiencies were low, and none of the participants had vitamin B12 or magnesium deficiency.
There were high prevalences of vitamin D, folate, vitamin B1, and iron deficiencies in bariatric patients in Korea. Nutritional deficiencies should be corrected prior to surgery to prevent subsequent further depletion. Routine analysis of vitamin B12, magnesium, copper, and selenium before surgery should be considered and studied in more detail.
所有减重手术都可能影响患者的营养状况，但营养缺乏因地区和文化而异。然而，东亚地区的减重患者没有术前营养指南。在这里，我们旨在评估东亚减重手术患者的术前营养状况。
我们对 2019 年 1 月至 12 月期间在韩国一家三级医院接受减重手术的 215 例连续患者进行了回顾性队列研究。手术前进行了医学背景评估、人体测量学测量和实验室检查。
80.0%的参与者存在维生素 D 缺乏，13.8%的参与者存在不足。维生素 D 缺乏或不足的患病率和平均维生素 D 浓度在性别之间无显著差异。维生素 B1（硫胺素）缺乏是第二常见的缺乏症（18.3%），其次是叶酸（14.2%）、铁（11.8%）和锌（7.6%）缺乏。男女贫血的患病率无显著差异（男性为 1.3%，女性为 7.4%，p=0.10），但女性缺铁的患病率明显更高（1.3%比 17.9%，p<0.001）。铜（2.3%）和硒（3.2%）缺乏的患病率较低，没有患者缺乏维生素 B12 或镁。
韩国减重患者存在较高的维生素 D、叶酸、维生素 B1 和铁缺乏率。手术前应纠正营养缺乏症，以防止术后进一步消耗。术前应考虑并更详细地研究常规分析维生素 B12、镁、铜和硒。
