Two other simple gauges that can reveal an association with OSA are neck size and weight to height ratio.  Women with a neck size greater than 14 ½” and men with a size 17” neck circumference or greater have an increased link to OSA. 

High height/weight ratio, body mass index (BMI), is also linked to increased chance of OSA.  The greater the BMI over 25 the greater the risk that you suffer from sleep obstructed breathing.  An easy to calculate BMI scale is provided below.  All you need is your height and weight to figure your BMI.
