One survey of 5,713 American residents identified habitual snoring in 24% of men and 13.8% of women, rising to 60% of men and 40% of women aged 60 to 65 years; this suggests an increased susceptibility to snoring with age.An observational study in the UK Biobank estimated that ~37% of 408,317 participants were habitual snorers, and confirmed positive associations with larger body-mass index, lower socio-economic status and more frequent smoking and alcohol consumption.

The forces responsible for the movement of the lateral body wall folds are poorly understood, and a better understanding of these forces would help to explain why gastroschisis occurs mostly to the right of the umbilicus, while other ventral body wall defects occur in the midline.At least six hypotheses have been proposed for the pathophysiology:

Failure of mesoderm to form in the body wall
Rupture of the amnion around the umbilical ring with subsequent herniation of bowel
Abnormal involution of the right umbilical vein leading to weakening of the body wall and gut herniation
Disruption of the right vitelline (yolk sac) artery with subsequent body wall damage and gut herniation
Abnormal folding of the body wall results in a ventral body wall defect through which the gut herniates
Failure to incorporate the yolk sac and related vitelline structures into the umbilical stalkThe first hypothesis does not explain why the mesoderm defect would occur in such a specific small area. The second hypothesis does not explain the low percentage of associated abnormality compared with omphalocele. The third hypothesis was criticized due to no vascular supplement of anterior abdominal wall by umbilical vein. The fourth hypothesis was commonly accepted, but it was later shown that the right vitelline artery (right omphalomesenteric artery) did not supply the anterior abdominal wall in this area. More evidence is needed to support the fifth hypothesis.
