Gestational diabetes mellitus (GDM)
- Gestational diabetes isn't
permanent but needs to be treated quickly.
- Results of previously conducted studies about association between serum selenium concentration and
gestational hyperglycemia are inconsistent.
- A study was undertaken to compare
the serum selenium concentration in women with GDM and normal pregnant
women via a systematic review and meta-analysis
- The study suggests that serum
selenium concentration is significantly lower in pregnant women with
gestational hyperglycemia compared to normal pregnant women.
which is diagnosed during pregnancy, is estimated to have affected nearly 14%
of pregnant women during the last few decades.
GDM is usually diagnosed during the 24-28 weeks of
‘Gestational diabetes is one of the most common diseases in pregnancy and could be associated with adverse outcomes and long-term metabolic derangements in the offspring.’
Risk factors affecting GDM include high maternal age,
family history of type 2 diabetes mellitus
, maternal obesity,
It was recently proposed that lack of an essential
trace element namely 'selenium' could be associated with the incidence of GDM.
Since oxidative stress is linked to etiology and pathogenesis of diabetes mellitus,
antioxidants like selenium are proposed to have a protective role.
However, the correlation between selenium status and
GDM is still controversial, hence a systematic review and meta-analysis were
undertaken to evaluate the relationship between serum selenium and GDM.
- A thorough, systematic literature
search was done in some of the published databases such as PubMed, The
Cochrane Library and Medline up to August 2016. Once the relevant original
studies were sorted out, a manual search was conducted of all the
references to these studies.
- Cochrane collaboration tool was
used to assess individual study quality for the risk of bias.
Gestational Diabetes - Facts and
- Out of the 44 citations which were
identified from three databases, a total of 7 studies involving 569 patients
were included for meta-analysis.
- It was seen that serum selenium
levels were lower in GDM patients as compared to the healthy controls with
- Subgroup analysis was further
carried out by geographic site and in different trimesters to obtain
thorough information from this meta-analysis.
- For non-Caucasian population, it
was seen that serum level of selenium decreased in GDM women especially in
the third trimester
- However, the authors indicate that
within the Caucasian population, index of selenium serum level showed no
- Diabetes is the most common
complication during pregnancy and represents 3.3% of all live births
- Gestational diabetes prevalence is
as high as 9.2%, according to a 2014 analysis by CDC
However, further well-designed
prospective studies are required involving large sample sizes to thoroughly
understand the relation between selenium status and GDM risk.
