1 in 18 kids in the Ancient Roman Empire had rickets (low Vitamin D)
Children in Ancient Rome had Vitamin D deficiency, study says CNN
“But when the researchers studied 2,787 skeletons of children and adults in 18 Roman Empire cemeteries from northern England to southern Spain, they realized that a lack of vitamin D is a longstanding issue for Europeans.”
“Of the skeletons studied, the prevalence of rickets in children was 5.7%”
“. Residual rickets was found in 3.2% of adults.”
Perhaps indoors too much - Northern Climate or apartments in Rome
Note by Vitamin D Life: What they really found was that of the kids who died, 5.6% of them had rickets.
Many of the other kids who did not die probably did not have rickets
Note: 3.2% of adults had residual rickets,
perhaps rickets rate for all kids was 4% (between 5.6% and 3.2 %) = 1 in 25
Latitude, urbanization, age, and sex as risk factors for vitamin D deficiency disease in the Roman Empire
