Abstract
This study was conducted at Endocrinology Department in
Ain Shams University hospital during the period from
February 2010 to Jun 2010.
This study was conducted on 40 subjects; all of them were
healthy females, aged between 15 and 30 years old.
Individuals who willing to participate in this study were
divided into two groups:
Group 1: (20) simple obese subjects; BMI between 30-40.
Group 2: (20) normal subjects; BMI between 18-24.
The aim of this study is to assess circadian rhythm of serum
cortisol level in μgm/dl and assess systolic and diastolic blood
pressure in mmHg in simple obese subjects.
The results of the study showed the following:
• There was no statistical significant difference between the
lean group and simple obese group either central or
gluteofemoral phenotypes as regards the mean serum cortisol
level in μcg/dl at different timings, mean systolic BP in
mmHg, mean diastolic BP in mmHg according to P value
(P>0.05) .
• There was a peak of serum cortisol level in μcg/dl at 9:00
followed by significant reduction till 12 am according to
paired t test and P value (P<0.05).
• On comparing the mean systolic and diastolic blood pressure
in mmHg at each timing with the preceding timing : there was
a statistical significant decrease in mean systolic and diastolic
pressure from 9 am till 3 pm in both lean and simple obese
groups according to paired t test and P value (P<0.05) then
followed by non significant decrease (P>0.05).
• There was no statsitical significant difference between
subjects with phenotype central and gluteofemoral simple
obesity as regards serum cortisol level in μgm/dl, systolic
blood pressure in mmHg and diastolic blood pressure in
mmHg according to P value (P>0.05).
