Neither latitude , region of the world , nor laboratory methodology were found to be associated with the prevalence of hypovitaminosis
BACKGROUND Hypovitaminosis D is considered a global public health issue .
Knowledge of its true dimensions will allow us to design interventions and plan preventive measures that can have a significant impact on human health .
OBJECTIVES The aim of this study was to evaluate the prevalence of hypovitaminosis D , defined as a serum 25-hydroxyvitamin D concentration < 30 ng/ml , in postmenopausal women around the world , as well as to identify the potential associated factors .
Vitamin D status in healthy Moroccan men and women aged 50 years and older: a cross-sectional study
Summary This study aim ed to compare the  vitamin D status  in healthy Moroccan men and women aged 50 years and older . A total of 186 Moroccan women and 68 men , who had no previous diagnosis of osteoporosis , were recruited prospect ively . We found in this study a high prevalence of hypovitaminosis D with no difference between men and women . Purpose The main purpose of this study was to describe and compare the  vitamin D status , parathormone , calcium , and phosphate  of healthy Moroccan men and women aged 50 years and older . Methods We conducted two cross-sectional studies , in postmenopausal women from October 2008 to November 2009 and in men over 50 years old , from December 2009 to August 2010 . A total of 186 Moroccan women and 68 men , who had no previous diagnosis of osteoporosis , were recruited prospect ively . For the definition of hypovitaminosis D , the preferred level for 25-hydroxyvitamin D ( 25(OH)D ) insufficiency , which is now recommended by many experts , is 30 ng/mL ( 75 nmol/L ) , and the levels below 10 ng/ml ( 25 nmol/L ) indicate deficiency . Results The prevalence of vitamin D deficiency in men and women was 4.4 and 8.6 % , respectively , and the prevalence of vitamin D(25(OH ) D ) insufficiency in men and women were 85.2 and 77.4 % , respectively . In men and women , no correlations were found between intact parathormone ( PTHi ) and 25(OH ) D ( r = 0.056 ) . Conclusions Despite a sunny environment , we found in this study a high prevalence of hypovitaminosis D ( insufficiency + deficiency ) in Moroccan men over 50 years old and postmenopausal women
