Introduction: The heart rate of adults is different in different sexes. Males have a lower basal heart rate than females. The purpose of this study is to investigate the effect of fetal gender on fetal basal heart rate.
Material and methods: A descriptive cross sectional study was conducted in Rajaii hospital-Tonekabon-Iran on 132 term pregnancies in 2019 with convenient sampling. Inclusion criteria were gestational age 37 weeks to 41 weeks, singleton pregnancy. Exclusion criteria were comprised of gestational age less than 37 or more than 41, fetal growth restriction, congenital malformations, use of psychoactive drugs, rupture of the amniotic sac, vaginal bleeding, onset Labor, drinking alcohol or smoking, unwillingness to participate in the study, suffering from underlying diseases (diabetes, blood pressure, thyroid and cancer) and multiple pregnancies. The data included fetal baseline heart rate, fetal sex, and maternal age. After collecting the data and entering in the checklist, the statistical information was confirmed and analyzed by SPSS software version 25.
Results: Of the 132 fetuses evaluated in this study, in the male fetuses, 50 fetuses had a heart rate of 110 to 135 and 16 fetuses had a heart rate of 136 to 160. In the female sex, 22 fetuses had a heart rate of 110 to 135 and 44 fetuses had a heart rate of 136 to 160. Based on the statistical evaluations, there was a statistically significant difference between the two groups (P=0.001), so that in the male gender, the base line heart rate was lower.
Conclusion: Based on the results observed in this evaluation, gender had a statistically significant correlation with the baseline heart rate of the fetus, being less in the male gender. However, more studies are needed in this field to confirm these results.
