Abstract | INTRODUCTION: PATIENTS AND METHODS: RESULTS: Five hundred and twenty-six subjects, mean age 54.6 years (71% women), were investigated throughout the year. 25OH vitamin D levels were correlated with sun exposure and varied according to the month of the year, unlike PTH and CTX levels. From November to May, over 90% of subjects had 25OH vitamin D levels<30ng/mL. Of the subjects who did not expose their face, arms and legs to the sun for at least 20min/day, 94% had 25OH vitamin D levels<30ng/mL. PTH levels were negatively correlated with those of 25OH vitamin D. Serum CTX levels were not correlated with PTH or 25OH vitamin D. Only 13% of subjects presented with secondary hyperparathyroidism, characterised by serum calcium<2.55mmol/L and PTH>65pg/mL, associated with increased CTX levels. CONCLUSION:
