A summary of research published in ERJ Open Research
Evidence suggests that there is a link between a lack of vitamin D, known as vitamin-D deficiency, and waking at night. This study aimed to look specifically at how a lack of vitamin D affected children who had been diagnosed with sleep apnoea.
127 children with sleep apnoea from a children’s clinic in Italy were included in the study. Researchers looked at measurements including weight and body-mass-index (BMI), and vitamin D levels. BMI estimates if you are in a healthy weight range for your height. They compared their findings from this group to a group of healthy children of a similar age.
The findings suggest a link between vitamin D levels and sleep apnoea. Results found:
The findings of this study suggest that vitamin D has a role to play in sleep apnoea. The authors note that other factors such as time spent outdoors and what seasons the data was recorded in, were not considered as part of this study. The group of children was quite small. The findings help to shed light on this complex issue where evidence is lacking. More research is needed to see if these results are confirmed through larger studies.
