Calcium is an essential element for the body, which is taken through the dietary sources. Calcium supplements may be needed to achieve the dietary reference intake (DRI). Dietary calcium and supplemental calcium intake for calcium balance might be necessary. However, increasing evidence shows that calcium supplementation may enhance soft tissue calcification and cause cardiovascular diseases. Calcium requirement during pregnancy is markedly increased. If calcium supplementation depends on the dietary style of a region, then the adequacy of dietary calcium intake may guide the calcium supplementation.
A cross-sectional descriptive study was conducted among pregnant women who attended prenatal care at Srinagarind Hospital, Khon Kaen University. We used semiquantitative food frequency questionnaire (SFFQ) to evaluate the amount of daily calcium intake, and 3 days food record to assess the SFFQ reliability. We used the INMUCAL-N V.3.0, based on the Thai food composition table for nutritional calculation.
Among 255 recruited pregnant women, the mean daily dietary calcium intake was 1,256.9 mg/day (SD: 625.1) and up to 1,413.4 mg/day (SD: 601.3) in daily milk consumed group. Based on Thai DRI for pregnant women, with 800 mg/day as adequate intake of calcium, 74.9% had adequate calcium intake, and majority of them had milk daily.
The majority of pregnant women in a province of Northeast Thailand had adequate calcium intake, particularly those who had milk with their meal every day.
钙是人体必需的元素，通过饮食来源获取。可能需要补充钙剂以达到膳食参考摄入量（DRI）。为维持钙平衡，膳食钙和补充钙的摄入可能是必要的。然而，越来越多的证据表明，补钙可能会增强软组织钙化并导致心血管疾病。孕期对钙的需求量显著增加。如果补钙取决于一个地区的饮食方式，那么膳食钙摄入量是否充足可能会指导补钙。
对孔敬大学诗里拉吉医院接受产前检查的孕妇进行了一项横断面描述性研究。我们使用半定量食物频率问卷（SFFQ）评估每日钙摄入量，并使用3天食物记录评估SFFQ的可靠性。我们使用基于泰国食物成分表的INMUCAL-N V.3.0进行营养计算。
在招募的255名孕妇中，每日膳食钙平均摄入量为1256.9毫克/天（标准差：625.1），在每日饮用牛奶组中高达1413.4毫克/天（标准差：601.3）。根据泰国孕妇的DRI，以每日800毫克作为充足的钙摄入量，74.9%的孕妇钙摄入量充足，且她们中的大多数人每天都喝牛奶。
泰国东北部一个省份的大多数孕妇钙摄入量充足，尤其是那些每天用餐时喝牛奶的孕妇。
