Vitamin D deficiency is common in Saudi Arabia. No sufficient data are available on the vitamin D status of preschool children.
To investigate the vitamin D status among toddlers and preschool children and to evaluate the factors associated with hypovitaminosis D in Western Saudi Arabia.
A cross-sectional study was conducted on 503 preschool children in Makkah. The children were divided into two age categories: 1 - 3 years (toddlers) and 3 - 6 years (preschool). Sociodemographic factors, life-style factors, eating habits, body mass index (BMI), 25-(OH)-vitamin D3, parathyroid hormone, calcium, phosphorous, and alkaline phosphatase concentrations were determined.
Sixty-three % of children had a vitamin D deficiency. Vitamin D in toddlers was significantly higher than in preschool children. Vitamin D levels were negatively correlated with BMI (r = - 0.419, P < 0.001), and duration of breast feeding (r = - 0.270, P = 0.027), but a significant positive correlation with vitamin D intake (r = 0.335, P = 0.021), calcium intake (r = 0.25, P = 0.029), duration of formula feeding (r = 0.354, P = 0.019), and outdoor physical activity (r = 0.381, P = 0.011) was found. Multivariable predictors of hypovitaminosis D were preschool age (OR = 11, [95 % CI: 2.78 - 43.57], P < 0.001), outdoor physical inactivity (OR = 2.44, [95 % CI: 0.93 - 14.12], P < 0.001), obesity (OR = 2.3, [95 % CI: 1.25 - 7.08], P = 0.008), overweight (OR = 2.16, [95 % CI: 1.18 - 6.01], P = 0.039), inadequate vitamin D intake (OR = 1.65, [95 % CI: 1.12 - 2.53], P = 0.012), exclusive formula feeding (OR = 0.53, [95 % CI: 0.41 - 0.72], P < 0.001), and breast and formula feeding (OR = 0.62 [95 % CI: 0.39 - 0.88], P = 0.002).
Hypovitaminosis D is a public health concern, especially in preschool children. Possible determinants of low vitamin D status in preschool children in the Makkah region could be related to age, high BMI, inadequate vitamin D intake, exclusive breastfeeding, and outdoor physical inactivity.
维生素D缺乏在沙特阿拉伯很常见。目前尚无关于学龄前儿童维生素D状况的充分数据。
调查沙特阿拉伯西部学步儿童和学龄前儿童的维生素D状况,并评估与维生素D缺乏症相关的因素。
对麦加的503名学龄前儿童进行了一项横断面研究。这些儿童被分为两个年龄组:1至3岁(学步儿童)和3至6岁(学龄前儿童)。测定了社会人口统计学因素、生活方式因素、饮食习惯、体重指数(BMI)、25-(OH)-维生素D3、甲状旁腺激素、钙、磷和碱性磷酸酶浓度。
63%的儿童存在维生素D缺乏。学步儿童的维生素D水平显著高于学龄前儿童。维生素D水平与BMI(r = -0.419,P < 0.001)和母乳喂养持续时间(r = -0.270,P = 0.027)呈负相关,但与维生素D摄入量(r = 0.335,P = 0.021)、钙摄入量(r = 0.25,P = 0.029)、配方奶喂养持续时间(r = 0.354,P = 0.019)和户外体育活动(r = 0.381,P = 0.011)呈显著正相关。维生素D缺乏症的多变量预测因素为学龄前年龄(OR = 11,[95%CI:2.78 - 43.57],P < 0.001)、户外体育活动不足(OR = 2.44,[95%CI:0.93 - 14.12],P < 0.001)、肥胖(OR = 2.3,[95%CI:1.25 - 7.08],P = 0.008)、超重(OR = 2.16,[95%CI:1.18 - 6.01],P = 0.039)、维生素D摄入不足(OR = 1.65,[95%CI:1.12 - 2.53],P = 0.012)、纯配方奶喂养(OR = 0.53,[95%CI:0.41 - 0.72],P < 0.001)以及母乳喂养和配方奶喂养(OR = 0.62 [95%CI:0.39 - 0.88],P = 0.002)。
维生素D缺乏是一个公共卫生问题,尤其是在学龄前儿童中。麦加地区学龄前儿童维生素D水平低的可能决定因素可能与年龄、高BMI、维生素D摄入不足、纯母乳喂养和户外体育活动不足有关。
