Individuals with diabetes, hypertension, cardiac arhythmmia, heart disease, obesity, heart-failure, stroke; and women with PCOS are significantly more likely to have OSA or some other form of SDB.
Due to a number of factors that include the penchant for weight-gain and reductions in the stiffness of the upper-airway musculature, individuals over 50 (and post-menopausal women) are at increased risk.
Males are significantly more likely to have OSA, however post-menopausal women approach the rate of men overall and women with PCOS are at significantly higher risk for OSA than women in general.
Aggressive snoring is a major indicator for upper-airway resistance and OSA. Body mass index (BMI) is also a good indicator but for some populations neck circumference is a better indicator that abdominal fat.
