Data on dietary calcium intake (DCI) from healthy North Indian adults are limited. Hence, the present study aims to assess DCI in healthy community-dwelling adults residing in an affluent North Indian city and correlate with serum biochemical parameters.
Healthy men and women were recruited from the community by door-to-door surveys. Serum total calcium, phosphate, 25-hydroxyvitamin D, and iPTH were estimated. DCI was assessed by recalling the diet consumed in the previous 7 days.
A total of 291 participants were included (mean age = 39.4 ± 12.9 years). The mean (± standard deviation) and median (inter-quartile range) DCI were 392.6 ± 169.1 mg/day and 391 (274-518) mg/day, respectively. DCI was higher in men compared with women. Only 21.3% of participants had DCI more than RDA (600 mg/day). Serum calcium was found to be significantly higher across each quartile of DCI. On multiple linear regression analysis, DCI emerged as an independent positive predictor of serum total calcium.
DCI is low in urban Indians. Promotion of consumption of dairy products and fortification of commonly consumed foods with calcium is needed.
来自健康的北印度成年人的膳食钙摄入量（DCI）数据有限。因此，本研究旨在评估居住在北印度一个富裕城市的健康社区成年人的DCI，并将其与血清生化参数相关联。
通过挨家挨户调查从社区招募健康男性和女性。测定血清总钙、磷酸盐、25-羟基维生素D和iPTH。通过回忆前7天的饮食来评估DCI。
共纳入291名参与者（平均年龄=39.4±12.9岁）。DCI的平均值（±标准差）和中位数（四分位间距）分别为392.6±169.1毫克/天和391（274-518）毫克/天。男性的DCI高于女性。只有21.3%的参与者的DCI超过推荐膳食摄入量（600毫克/天）。在DCI的每个四分位数中，血清钙均显著更高。多元线性回归分析显示，DCI是血清总钙的独立正向预测因子。
城市印度人的DCI较低。需要推广乳制品消费，并对常见食物进行钙强化。
