I’ve reported on a number of various factors that increases your risk factor for obstructive sleep apnea, but here’s an unexpected one: premature delivery. Researchers from Australia showed that premature delivery increases your chances of developing obstructive sleep apnea later in life by 2.74 times full-term deliveries. It makes sense that you need to be in your mother’s womb for the full 39-40 weeks so that your facial and jaw structures have a chance to develop and mature adequately. Surprisingly, this same study showed that low-weight for gestational age were not at increased risk for obstructive sleep apnea. It’s also been shown in other studies that pregnant mothers with obstructive sleep apnea have a higher rate of premature births.
