背景
在亚洲人群中进行的维生素D营养研究很少。
目的
目的是评估25-羟基维生素D [25（OH）D]浓度在健康的老年日本妇女在冬季，并确定是否25（OH）D浓度与生活方式。
设计
我们于1999年2月调查了151名年龄为66.5 ± 6.7岁（f1.gif”BORDER=“0”> +/- SD）的农村社区妇女。血清25（OH）D和全段甲状旁腺激素分别用高效液相色谱法和免疫放射法测定。生活方式因素的信息，包括阳光照射和富含维生素D的食物的消费，也通过采访获得。
结果
平均（+/-SD）25（OH）D浓度为59.9 +/- 17.0 nmol/L。在4.6%的妇女中发现维生素D缺乏（<30 nmol/L），该值低于白色人群。年龄与25（OH）D浓度无相关性（r = 0.004，P = 0.957）。经常吃鱼（≥ 4次/周）的受试者的25（OH）D浓度比中等吃鱼（1-3次/周）的受试者高10.1nmol/L（P < 0.001）。此外，不吃鸡蛋的人25（OH）D浓度显著低于吃鸡蛋≥ 1次/周的人（P < 0.05）。
结论
日本人的维生素D营养状况似乎比大多数西方人好。经常食用鱼类被认为有助于在冬季维持日本老年妇女血清25（OH）D的足够浓度。
BACKGROUND
Few studies of vitamin D nutrition in Asian populations have been conducted.
OBJECTIVE
The objective was to assess 25-hydroxyvitamin D [25(OH)D] concentrations in healthy elderly Japanese women during the winter and to determine whether 25(OH)D concentrations are associated with lifestyle.
DESIGN
We investigated 151 women aged 66.5 +/- 6.7 y (f1.gif" BORDER="0"> +/- SD) living in a rural community in February 1999. Serum 25(OH)D and intact parathyroid hormone were measured by using HPLC and an immunoradiometric assay, respectively. Information on lifestyle factors, including sunshine exposure and the consumption of vitamin D-rich foods, was also obtained through an interview.
RESULTS
The mean (+/-SD) 25(OH)D concentration was 59.9 +/- 17.0 nmol/L. Vitamin D insufficiencies (<30 nmol/L) were found in 4.6% of the women, a value lower than that found in white populations. No correlation was found between age and 25(OH)D concentrations (r = 0.004, P = 0.957). The 25(OH)D concentration of subjects who consumed fish frequently (>/=4 times/wk) was 10.1 nmol/L higher (P < 0.001) than that of subjects with a moderate consumption of fish (1-3 times/wk). Additionally, those who did not consume eggs had significantly lower 25(OH)D concentrations than did those who consumed eggs >/=1 time/wk (P < 0.05).
CONCLUSIONS
: The nutritional status of vitamin D in Japanese populations seems to be better than that in most Western populations. Frequent fish consumption is believed to help maintain adequate concentrations of serum 25(OH)D in elderly Japanese women during the winter.
