BACKGROUND/OBJECTIVES: Recent studies showed vitamin D deficiency is linked to chronic diseases in addition to skeletal metabolism which could threaten the elderly. We analyzed health conditions and socio-demographic factors associated with vitamin D deficiency in community dwelling people aged 65 years and older.
SUBJECTS/METHOD: Data from the Korea National Health and Nutrition Examination Survey (KNHANES) 2010 to 2012 were obtained. A total of 2,687 subjects aged 65 years and older were participated. The cutoff value of the Vitamin D deficiency was considered as serum 25-hydroxyvitamin D [25(OH)D] ≤ 20 ng/mL (50 nmol/L).
The overall prevalence rate of vitamin D deficiency in the elderly was 62.1%. The factors such as female, obesity, metabolic syndrome, current smoker, and skipping breakfast were positively associated with vitamin D deficiency, but high intensity of physical activity and more than 9 hours of sleep duration were negatively associated with vitamin D deficiency (all < 0.05).
It is important that health professions know that the factors proved in this study are connected to vitamin D deficiency thus provide information and intervention strategies of vitamin D deficiency to old aged people.
背景/目的：近期研究表明，维生素D缺乏除了会影响骨骼代谢外，还与慢性疾病有关，这可能会对老年人构成威胁。我们分析了65岁及以上社区居民中与维生素D缺乏相关的健康状况和社会人口学因素。
对象/方法：获取了2010年至2012年韩国国家健康与营养检查调查（KNHANES）的数据。共有2687名65岁及以上的受试者参与。维生素D缺乏的临界值被认为是血清25-羟基维生素D[25(OH)D]≤20 ng/mL（50 nmol/L）。
老年人维生素D缺乏的总体患病率为62.1%。女性、肥胖、代谢综合征、当前吸烟者和不吃早餐等因素与维生素D缺乏呈正相关，但高强度体育活动和睡眠时间超过9小时与维生素D缺乏呈负相关（均P<0.05）。
医疗专业人员了解本研究中证实的因素与维生素D缺乏有关非常重要，这样可以为老年人提供维生素D缺乏的信息和干预策略。
