Prevalence
The prevalence of vitamin K deficiency varies by geographic region.
For infants in the United States, vitamin K1 deficiency without bleeding may occur in as many as 50% of infants younger than 5 days old. Therefore, the Committee on Nutrition of the American Academy of Pediatrics recommends that 0.5 to 1.0 mg Vitamin K1 be administered to all newborns shortly after birth.
Postmenopausal and elderly women in Thailand have high risk of Vitamin K2 deficiency, compared with the normal value of young, reproductive females. Current dosage recommendations for Vitamin K may be too low.
