Vitamin D and retinol insufficiency rates approach 100% in both genders across adult and elderly age groups in Iran, representing a critical public health gap.
Vitamin D and Retinol (Vitamin A) are critically low in this population, affecting nearly everyone. Dietary changes alone may not be enough; consider supplementation or fortified foods to address this widespread deficiency.
GoodSupportsHIGH confidence
The percentage of insufficiency was around 100% for retinol and vitamin D in both genders.
Why this rating
Large sample size and consistent findings across age groups and genders.
