title: The relationship between neck circumference and pregnancy-induced hypertension in the third trimester pregnant women.
abstract: OBJECTIVE
  The purpose of this study was to evaluate the relationship between neck circumference (NC) and pregnancy-induced hypertension (PIH) in the third trimester pregnant women.
  
  
  METHODS
  The study included 126 women who were in the third trimester pregnancy. All subjects completed a standard sleep questionnaire, anthropometric measurements and ultrasonic testing.
  
  
  RESULTS
  Pregnant women with NC ≥34.7 cm had significantly higher frequency of PIH than pregnant women with NC <34.7 cm (35.6% versus 2.5%, χ(2 )= 25.863, p = 0.000).
  
  
  CONCLUSIONS
  The increase of NC was independent risk factor for PIH in the third trimester pregnant women.
