Low Serum Magnesium in Preterm Labour
This study was designed to compare serum magnesium level
in women with preterm labour and with those who were in
A case-control study was carried out in the department of
Obstetrics and Gynaecology, Bangabandhu Sheikh Mujib
Medical University (BSMMU), Dhaka from July 2005 to
June 2007, to evaluate serum magnesium level in women
with preterm labour (28-36 weeks) and compare them with
those who were in term labour (37-40 weeks). The total
number of cases was 160, of which 80 were cases and similar
number were control.
The study subjects were selected from inpatient department
of Obstetrics and Gynaecology, BSMMU and Mother and
Child Health Training Institute (MCHTI), Dhaka.
Serum magnesium level was measured by taking 5 ml of blood
from women with term (control) and preterm labour (case).
The basic characteristics, like age, parity and socioeconomic
status did not show statistically any significant difference
between control arid case groups, but showed significant
difference only in the body mass index between the two
groups. Mean (±SD) BMI in control and case groups were
24.88±1.42 and 23.12±2.36 kg/m2 respectively.
Mean (±SD) gestational age were 38.95±0.89 and
33.03±1.83 weeks, respectively in control and case groups.
The mean (±SD) serum magnesium levels were 2.02±0.20
(range 1.70-2.4) and 1.65±0.19 (range 1.30-2.00) mg/dl,
respectively, in control and case groups. ‘The difference was
highly significant (p<0.001).
