One study that did measure Vitamin D levels and related it to UVR behavior, correlated the mean daily hours measured by dosimeter in September and Feburary (r=0.64, P=0.001) and (r=0.53; P=0.007) [35], however, the study did not look into correlation between Vitamin D and scores for sunlight diaries or questionnaires.There were a few limitations to our study.
