This prospective study examined the need for a large cuff during pregnancy and its correlation with maternal obesity. METHODS: Maternal body mass index (BMI), fat mass, and MAC were measured. RESULTS: Of 179 women studied, 15.6% were obese. With a BMI of level 1 obesity, 44% needed a large cuff and with a BMI of level 2 obesity 100% needed a large cuff. CONCLUSION: All women booking for antenatal care should have their MAC measured to avoid the overdiagnosis of pregnancy hypertension.engAdolescentAdultBlood PressureBlood Pressure Determination/*instrumentationBody Mass IndexFemaleHumansHypertension, Pregnancy-Induced/*diagnosis/physiopathology*ObesityPredictive Value of TestsPregnancyPregnancy Trimesters*Prenatal DiagnosisProspective StudiesBody mass index and blood pressure measurement during pregnancy.Hypertension in pregnancy : official journal of the International Society for the, Study of Hypertension in Pregnancy
