TOXICITY

17. PREVALENCE OF VITAMIN D DEFICIENY ON AN
AVERAGE IN ADULTS WORLDWIDE
100 IU (2.5 mcg) per day
increases vitamin D blood levels
1 ng/ml (2.5 nmol/L)
Vitamin D deficiency is not
only a problem in India but
also in countries like
Pakistan, China, middle-
East and Africa. It is
relatively less common in
Japan, USA, Canada and
South-east Asia. In USA
and Canada, milk is usually
fortified with Vitamin D and
the use of vitamin
supplements is common.

18.  As estimated, 1 billion people worldwide have Vitamin D deficiency or insufficiency
and is very common in India in all the age groups and both sexes across the country.
 Apart from low dietary intake, people suffering from calcium deficiencies, diabetes,
hepatic, renal, dermatological disorders, alcoholics and inflammatory
rheumatological conditions also mostly have Vit D deficiency.
 As per the report of International Osteoporosis Foundation, in Northern India, 96%
of noenates, 91% of healthy school girls, 78% of healthy hospital staff, and 84% of
pregnant women were found to have hypovitaminosis D. On the other hand,
prevalence of vitamin D deficiency in Southern India was estimated to be 40% among
males and 70% among females. There was also a significant rural urban variation in
the vitamin D deficiency status that was attributed to the diversity of occupation
which the people were involved in.
