Abstract
P
reeclampsia is defined as the presence of a systolic blood pressure ≥ 140 mm Hg or a diastolic blood pressure ≥ 90 mm Hg, on 2 occasions at least 4 hours apart in a previously normotensive patient. In addition to the blood pressure criteria, proteinuria of ≥ 0.3 grams in a 24-hour urine collection, a protein (mg/dl)/ creatinine (mg/dl) ratio of 0.3 or higher, or a urine dipstick protein of 1+ is required to diagnose preeclampsia (Jeyabalan et al., 2013).
As preeclampsia presents at varied gestational ages and varies in severity, two distinct subtypes have been recognized. Early onset preeclampsia occurs prior to 34 weeks gestation, and late onset preeclampsia occurs at or beyond 34 weeks gestation (Lisonkova et al., 2013).
Severe pre-eclampsia is pre-eclampsia with severe hypertension and/or with symptoms, and/or biochemical and/or haematological impairment (NICE clinical guideline, 2011).
Obesity now affects more than one-third of reproductive-aged women, and escalating rates of obesity may contribute to an increased prevalence of hypertensive disorders in pregnancy (Bodnar et al., 2007).
There is agreat need to study the relation between BMI and the rate of developing preeclampsia, time of onset and severity.
The aim of our study is to identify the relation between obesity and development of PET, its relation with onset and severity of PET.
Our study was conducted on 200 pregnant women (100 obese with BMI ≥ 30 kg/m2, 100 non-obese with BMI <30 kg/m2 at booking (6-10 weeks gestation).
Follow up of both groups was done through out pregnancy, in every visit we measured blood pressure, proteinuria, weight, Symphysio fundal height.
According to follow up results we classify study groups as normal blood pressure, gestational hypertension, pre-eclampsia and then also classify PET patients as early, late onset and mild, severe PET.
Results of current study showed that:
There was a statistically significant difference between obese and non obese groups as regard occurrence of pre-eclampsia. incidence of PET in both groups was 5.5% while incidence of PET among obese group was 9 % and its incidende among non obese group was 2%.
There was a highly statistically significant difference between the 2 studied groups of patients as regard 1st visit SBP, DBP and also last visit SBP, DBP.
There was a statistically insignificant difference between obese and non-obese groups as regard onset of pre-eclampsia.
There was a statistically insignificant difference between obese and non-obese groups as regard severity of pre-eclampsia.
