Abstract
Desalination of seawater is one of the important options for Egypt to face the shortage of water expected in the next few years.
Ion composition of drinking water especially fluoride,calcium and magnesium have potential effect on bone health.
The main difference between desalinated water and bottled water is the absence of fluoride in desalinated water, the amount of magnesium and calcium in desalinated water is slightly different from various types of bottled water.
The present work was done to assess the effects of
drinking desalinated seawater on the formation and growth of Children’s bone.
153 children; their ages ranged from 8-12years from both sexes were examined clinically and checked for: the bone mineral density by the use of a quantitative ultrasound machine to measure the broadband ultrasound attenuation (BUA ) of the calcaneus bone of both feet , serum calcium,
serum phosphorus, serum magnesium, serum alkaline phosphatase and hemoglobin level.Those children were divided into three groups according to the type of drinking water they used since birth; group 1 used desalinated water only, group 2 used bottled water only and group 3 used mixed water.
There was a non significant difference between all groups regarding age, sex, body mass index , serum calcium, serum phosphorus, serum magnesium, serum alkaline phosphatase,
or hemoglobin level.
There was a significant statistical difference between group 1 and group 2 in children 8-10 years old and in girls only 10 to 12 years old, regarding the BUA. Children of group 2 had higher BUA than group 1 in those age groups,
which may indicate a probable advantage for drinking fluoride-containing bottled water over desalinated fluoride free water.
