dc.description.abstract | BACKGROUND AND OBJECTIVES:
This study assessed vitamin D status and its determinants in a cohort of octogenarians living within New Zealand’s Bay of Plenty and Lakes Districts.
METHODS AND STUDY DESIGN:
Serum 25-hydroxyvitamin D [25(OH)D] concentration was measured in 209 Māori (aged 80-90 years) and 357 non-Māori (85 years), along with demographic, lifestyle, supplement use and other health data.
RESULTS:
Mean [95% CI] 25(OH)D concentration was 69 [67 to 72] nmol/L, with 15% >100 nmol/Land 6 individuals >150 nmol/L. Concentrations in Māori (59 [55 to 62] 4 nmol/L) were lower than in non-Māori (75 [72 to 78] nmol/L; p<0.001), a difference maintained when adjusted for day-of-year measured. Vitamin D supplementation was reported by 98 participants (18%): including a greater proportion of women (24%) than men (11%; p<0.001) and of non-Māori (24%) than Māori (7%; p<0.001). Of those taking vitamin D, 49% took high oral doses (≥25 μg/day or equiva-lent) and five individuals took >50 μg/day. Vitamin D supplement use strongly and independently predicted seasonally adjusted 25(OH)D concentration and was associated with 28 nmol/L higher levels than non-use. Other predictors included Māori ethnicity (10nmol/L lower concentration than for non-Māori), and female gender (11 nmol/L lower).
CONCLUSIONS:
Vitamin D status in New Zealand octogenarians appears higher than previously re-ported, particularly in non-Māori compared to Māori. Prescribed and non-prescribed oral vitamin D supplementation is prevalent in this group and a strong indicator of vitamin D status.
新西兰毛利族和非毛利族八旬老人维生素D状况:
一项
队列研究背景与目的:本研究评估了队列研究中 生活在新西兰湾和湖泊区域的八旬老人的维生素D状况及其决定因素。
方法与研究设计:
测量209名毛利人(80-90岁)和357名非毛利人(85岁)的血清25-羟维生素D(25(OH)D)的浓度,同时收集研究对象的体格测量指标、生活方式、
补充剂的应用和其它健康资料。
结果:
平均25(OH)D浓度为69(95% CI:67-72)nmol/L,其中15%的研究对象>100 nmol/L,6个研究对象>150 nmol/L。毛利人的25(OH)D浓度(59 nmol/L,95% CI: 55-62 nmol/L)低于非毛利人(75 nmol/L,95% CI:72-78 nmol/L,p<0.001),校正测量日期后,差异仍然存在。98名(占18%)研对象报告补充了维生素D,女性中补充者所占的比例(24%)高于男性(11%,p<0.001),非毛利人中补充者所占的比例高于毛利人。补充维生素D的人中,49%的人摄入高剂量(每天≥25 μg或相当剂量),5个研究对象每天摄入维生素D≥50 μg。维生素D补充剂的应用能够强而独立地预测季节校正的25(OH)D浓度,并且使用者比不用者高28 nmol/L。其它预测指标包括毛利族(比非毛利族低10 nmol/L)和女性性别(比男性低11 nmol/L)。
结论:
新西兰八旬老人维 生素D浓度高于以前的报告,尤其是非毛利人。这个人群中处方和非处方口服维生素D补充剂普遍存在,并且是维生素状态的强预测指标。 | en_NZ |
