Introduction Vitamin D serum dosage evaluation in 40 women submitted to the WHO Healthy Life Quality—SHORT FORM 36 (SF-36).

Methods Cross-sectional, random study of 40 patients in a private practice, submitted to the SF-36 questionnaire and to a Vitamin D serum dosage.

Results Average age is 52 years (±8.58); 95% of participants have a college degree. The great majority displays skin pigmentation between levels II (40%) and II/III (55%), according to the Fitzgerald Skin Types, and 75% of them relate scarce sun exposure. The average dosage of Vitamin D is 20.05 ng/ml (±7.96), and insufficient levels (<30 ng/ml) were detected in 90% of the patients. However, the analysis of the SF-36 revealed positive perception of both physical and mental health, with more than 70% of favourable answers to the items analysed, including degree of pain, vitality, physical aspects, functional capacity, social and emotional aspects, and mental health. In spite of that, 92.5% declare little leisure time.

Conclusions The reduction of Vitamin D was positively related with low sun exposure, not associated with skin colour or quality of life. Based on these results, the high incidence of hypovitaminosis D in women from a tropical country leads us to suggest the importance of a routine dosage of Vitamin D.
