摘要

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 卤 337 mg/d for CBC and 809 卤 369 mg/d for ABC (P = .737). Vitamin D intake was 3.8 卤 3.4 渭g/d for CBC and 5.0 卤 3.9 渭g/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.
