A new study published in PLOS One has found that higher vitamin D levels may reduce the risk of developing nocturnal enuresis in children.
Nocturnal enuresis (NE) is also known as nighttime bedwetting in children over the age of five years old. Approximately five million children in the United States have NE.
One of the causes of NE is thought to be related to sleep disorders. While research hasn’t explored whether vitamin D plays any role in NE, there have been studies to show a relationship between vitamin D and sleep regulation.
Researchers out of China recently conducted a study to determine if vitamin D was related to NE.
They recruited 247 children aged five to seven years old with NE and measured their vitamin D levels. They wanted to see if vitamin D was related to NE and if having a certain vitamin D level affected their risk of developing NE.
They found that the prevalence of NE decreased as vitamin D levels increased. NE was prevalent in 7.3% of children with vitamin D levels above 20 ng/ml, while 17.5% of the children with vitamin D levels less than 20 ng/ml had NE.
“In the present study, a statistically significant association was found between serum [vitamin D] and NE,” the researchers concluded. “Our data revealed that children with lower [vitamin D] concentrations were at an increased risk of NE.”
With this being one of the first studies to find a relationship between vitamin D and NE, the researchers call for future studies to confirm this relationship and determine any mechanisms behind it.
