Vitamin-D deficiency is a universal health problem caused primarily by inadequate exposure to sunlight. This study aimed to assess the vitamin D status and investigate the factors affecting vitamin D distribution among Saudi males.
A cross-sectional study was conducted at the King Saud University Medical City from December 2015 to August 2016. Saudi males attending the outpatient primary health care clinics were invited to participate in the study. Data were collected on the current and past health status along with biochemical investigations for total 25-hydroxyvitamin D (25OHD), blood sugar, and cholesterol.
Majority of the participants (76.1%) had vitamin D deficiency. Blood sugar level, age, and cholesterol level were the most significant factors associated with vitamin D status. The highest percentage of deficiency was observed in the youngest age group (30-40 years). With increasing age, the percentage of deficiency decreased significantly. Those with normal blood sugar and cholesterol level had higher serum vitamin D levels compared to those with diabetes and hypercholesterolemia.
Vitamin D deficiency is still endemic in Saudi Arabia, particularly among younger males and those with diabetes and hypercholesterolemia. Vitamin D screening, supplementations, and vitamin D-fortified foods should be provided especially for these groups.
维生素 D 缺乏是一个普遍存在的健康问题，主要是由于暴露在阳光下不足所致。本研究旨在评估沙特男性的维生素 D 状况，并调查影响维生素 D 分布的因素。
本研究于 2015 年 12 月至 2016 年 8 月在沙特国王大学医学城进行了一项横断面研究。邀请在门诊初级保健诊所就诊的沙特男性参加这项研究。收集了当前和过去的健康状况以及总 25-羟维生素 D（25OHD）、血糖和胆固醇的生化检查数据。
大多数参与者（76.1%）存在维生素 D 缺乏。血糖水平、年龄和胆固醇水平是与维生素 D 状态最相关的重要因素。在最年轻的年龄组（30-40 岁）中观察到缺乏的百分比最高。随着年龄的增加，缺乏的百分比显著下降。与糖尿病和高胆固醇血症患者相比，血糖和胆固醇水平正常的患者血清维生素 D 水平更高。
维生素 D 缺乏在沙特阿拉伯仍然普遍存在，尤其是在年轻男性以及患有糖尿病和高胆固醇血症的人群中。应特别为这些人群提供维生素 D 筛查、补充剂和维生素 D 强化食品。
