Abstract
Background and aims: Hypothyroidism is the most prevalent cause of mental dysfunctions. The
rate of this problem in Iran is higher than the average rate of the world. Other studies have shown
different prevalence rates of this disease. The aim of this study was to investigate the effect of caesarean
operation on the increase of hypothyroidism.
Methods: This study was a case-control study performed on the newborns in Chadegan County during
2016-2017. The number of cases (TSH >3.5) was 84 and the number of controls (TSH ≤3.5) was
176. After matching at individual and group levels,analysis was done based on odds ratio and the
confidence interval.
Results: This study showed that there was no relationship between caesarean and hypothyroidism
(odds ratio [OR] = 1.235) with the confidence interval of 0.73-2.08.
Conclusion: This study did not show any relationship between caesarean and hypothyroidism and
therefore the role of other risk factors especially genetic and environmental risk factors should be
emphasized. Other studies also reported such relationship.
