To determine the prevalence of vitamin D deficiency in healthy Saudi adults.
A cross-sectional study carried out as part of the screening and early evaluation of kidney disease project. Vitamin D was measured in subjects recruited at 2 screening camps in Riyadh, Saudi Arabia, between March to May 2008. Subjects from the 2 large commercial centers in Riyadh aged ≥18 years and Saudi nationals were invited.
The study sample comprised of 488 subjects. The mean age of the subjects was 37.43 (11.32) years, of which 50.2% (n=245) were males. Twenty-nine percent of subjects were in the vitamin D deficiency group, 22.7% were in the relative insufficiency group, and 47.5% had normal levels of 25-hydroxy vitamin D. We observed that female gender was an independent predictor of vitamin D deficiency or insufficiency (odds ratio [OR]: 2.992; 95% confidence intervals [CI] 2.069-4.327). Anemia was also a predictor for vitamin D deficiency or insufficiency (OR: 3.16; 95% CI 2.02-4.92). Age was positively correlated with vitamin D levels (Pearson correlation=0.183, p<0.000).
Vitamin D deficiency is common in healthy Saudi adults. This is more pronounced in females and in the younger age groups. Wearing of traditional clothes, deliberate avoidance of the sun, and inadequate dietary intake are likely to be the principal causes of low vitamin D levels.
确定沙特健康成年人维生素D缺乏症的患病率。
作为肾脏疾病项目筛查和早期评估的一部分开展的一项横断面研究。2008年3月至5月期间，在沙特阿拉伯利雅得的2个筛查营地对招募的受试者进行了维生素D检测。邀请了利雅得2个大型商业中心年龄≥18岁的沙特国民。
研究样本包括488名受试者。受试者的平均年龄为37.43（11.32）岁，其中50.2%（n=245）为男性。29%的受试者属于维生素D缺乏组，22.7%属于相对不足组，47.5%的25-羟维生素D水平正常。我们观察到女性是维生素D缺乏或不足的独立预测因素（优势比[OR]：2.992；95%置信区间[CI]2.069 - 4.327）。贫血也是维生素D缺乏或不足的一个预测因素（OR：3.16；95%CI 2.02 - 4.92）。年龄与维生素D水平呈正相关（Pearson相关系数=0.183，p<0.000）。
维生素D缺乏在沙特健康成年人中很常见。在女性和较年轻年龄组中更为明显。穿着传统服装、刻意避免日晒和饮食摄入不足可能是维生素D水平低的主要原因。
