Low intakes of calcium and vitamin D increase the risk for osteoporosis, bone fracture, and other health problems. This study aimed to examine the calcium and vitamin D intakes of Canadian-born Chinese (CBC) and Asian-born Chinese (ABC) in Edmonton, Canada, and to identify usual food sources of these nutrients. We hypothesized that CBC would have higher intakes of calcium and vitamin D than ABC and that the food sources of these nutrients would differ by region of birth (Canada vs Asia). Two in-person multipass 24-hour dietary recalls were administered for 1 weekday and weekend day for 81 healthy ethnically Chinese aged 18 to 58 years. The risks for calcium and vitamin D inadequacy were calculated as were the contributions of specific foods to calcium and vitamin D intakes. Calcium intake was 781 ± 337 mg/d for CBC and 809 ± 369 mg/d for ABC (P = .737). Vitamin D intake was 3.8 ± 3.4 μg/d for CBC and 5.0 ± 3.9 μg/d for ABC (P = .158). Respective risks for calcium and vitamin D inadequacy were 36% and 98% for men and 78% and 100% for women. Dairy contributed most to the calcium (43%) and vitamin D (52%) intake of participants. For ABC, soybean products contributed to 8.1% of calcium, whereas fatty fish contributed to 16.7% of vitamin D. For CBC, red meats contributed to 11.1% of vitamin D. Dietary intakes of calcium and vitamin D need to be increased in Chinese Canadians through the promotion of dairy and culturally relevant sources of these nutrients.
钙和维生素 D 摄入量低会增加骨质疏松症、骨折和其他健康问题的风险。本研究旨在调查加拿大出生的华人 (CBC) 和亚洲出生的华人 (ABC) 在加拿大埃德蒙顿的钙和维生素 D 摄入量,并确定这些营养素的常见食物来源。我们假设 CBC 的钙和维生素 D 摄入量高于 ABC,并且这些营养素的食物来源因出生地区 (加拿大与亚洲) 而异。对 81 名年龄在 18 至 58 岁的健康华裔进行了 2 次面对面的多次 24 小时膳食回忆,分别在 1 个工作日和周末进行。计算了钙和维生素 D 不足的风险,并计算了特定食物对钙和维生素 D 摄入量的贡献。CBC 的钙摄入量为 781 ± 337mg/d,ABC 为 809 ± 369mg/d(P =.737)。CBC 的维生素 D 摄入量为 3.8 ± 3.4μg/d,ABC 为 5.0 ± 3.9μg/d(P =.158)。相应的钙和维生素 D 不足风险分别为男性 36%和 98%,女性 78%和 100%。乳制品对参与者的钙 (43%) 和维生素 D (52%) 摄入量贡献最大。对于 ABC,大豆制品对钙的贡献率为 8.1%,而高脂肪鱼类对维生素 D 的贡献率为 16.7%。对于 CBC,红肉对维生素 D 的贡献率为 11.1%。需要通过促进乳制品和这些营养素的文化相关来源来增加加拿大华人的钙和维生素 D 摄入量。
