Vitamin D is essential for skeletal health. Because peak bone mass accrual occurs during childhood and adolescence, vitamin D insufficiency during this period of life could cause adverse health outcomes.
To explore the potential sex differences in anthropometric indicators and vitamin D status among primary school-age children.
A modified food-frequency intake questionnaire was completed by 116 pre-pubertal children (52 girls, 64 boys). Body measurements were recorded and blood was drawn to assess vitamin D status. All children were of Arab-Israeli origin and lived in villages or rural areas in the north-east area of Israel.
Prevalence of obesity was higher among girls (34%) compared to boys (21.9%, P = 0.018). All the children were vitamin D insufficient, and 80% were deficient. Plasma vitamin D was significantly higher among boys (12.4 ng/ml) compared to girls (9.1 ng/ml, P < 0.01). A significant negative correlation was found between vitamin D status and weight percentile for girls (r = -0.43, P < 0.05) but not for boys. There was a trend toward a statistically significant inverse correlation between vitamin D status and body fat percent in the girls (r = -0.37, P = 0.07). Sex frameworks are important for the understanding of the determinants of health and the development of effective health promotion programs.
Pre-pubertal girls in Arab villages should be provided with tailor-made nutrition and physical activity programs for promoting health.
维生素D对骨骼健康至关重要。由于儿童期和青春期会积累峰值骨量，这一时期维生素D不足可能会导致不良健康后果。
探讨小学适龄儿童人体测量指标和维生素D状况的潜在性别差异。
116名青春期前儿童（52名女孩，64名男孩）完成了一份改良的食物频率摄入问卷。记录身体测量数据并采集血液以评估维生素D状况。所有儿童均为阿拉伯裔以色列人，居住在以色列东北部的村庄或农村地区。
女孩的肥胖患病率（34%）高于男孩（21.9%，P = 0.018）。所有儿童维生素D均不足，80%的儿童维生素D缺乏。男孩的血浆维生素D水平（12.4 ng/ml）显著高于女孩（9.1 ng/ml，P < 0.01）。女孩的维生素D状况与体重百分位数之间存在显著负相关（r = -0.43，P < 0.05），而男孩不存在这种相关性。女孩的维生素D状况与体脂百分比之间存在统计学显著负相关的趋势（r = -0.37，P = 0.07）。性别框架对于理解健康的决定因素和制定有效的健康促进计划很重要。
应向阿拉伯村庄的青春期前女孩提供量身定制的营养和体育活动计划以促进健康。
