The results of the present study emphasize the importance of 25-hydroxyvitamin D measurement, and the need to increase vitamin D intake in Italy; foodstuff fortification and supplement use must be considered in order to prevent negative effects of vitamin D deficiency on skeletal integrity.
All hospitalized patients, both in summer and in winter,
are characterized by the highest prevalence of hypovitaminosis
D, especially the older patients. Medical
inpatients may be at risk for vitamin D deficiency,

CONCLUSION: Hypovitaminosis D is very common amongst Finnish in- and outpatients in both sexes, causing secondary hyperparathyroidism in females. More extensive studies are warranted to elucidate the vitamin D status of the Finnish population.
