				        	BACKGROUND: Despite daily vitamin D recommendations, women with osteoporosis may not achieve optimal 25-hydroxy-vitamin D (25[OH]D) levels. We retrospectively evaluated the effect of education and vitamin D supplementation (1,000 IU/day) in Korean women with osteoporosis. METHODS: Sixty-one women with osteoporosis who were taking cholecalciferol (800–1,000 IU/day) were enrolled during 2011 to 2012. Forty patients (education only, Edu group) were educated on the importance of >30 min sunlight exposure daily while taking vitamin D. Twenty-one patients (education with vitamin D supplementation, Add group) were prescribed 1,000 IU/day cholecalciferol (total 1,800–2,000 IU/day) plus education. Patients were divided into 3 groups according to serum 25(OH)D status: deficiency (<20 ng/mL), insufficiency (20–30 ng/mL), and sufficiency (≥30 ng/mL). Furthermore, 25(OH)D levels were compared at baseline and after intervention for 3 months. RESULTS: The median (interquartile range) serum 25(OH)D concentration at baseline was 25.10 (18.95–33.60) ng/mL. The mean (±standard error) differences in 25(OH)D levels from baseline to post-intervention were 19.85±3.86 and 31.73±4.82 ng/mL in the Edu group and Add group, respectively. Eighteen patients (29.5%) had vitamin D deficiency, 25 (41.0%) had insufficiency, and 18 (29.5%) had sufficient levels. Optimal 25(OH)D (30 ng/mL or more) was achieved in 54.5% and 95.2% patients in the Edu group and Add group, respectively (P=0.003). CONCLUSIONS: We consider that vitamin D concentration should be measured on a regular basis in order to maintain an optimal level of vitamin D concentration, and education and supplementation is needed if not sufficient.
