Brief Summary

Introduction: Prenatal tests can increase the stress levels of pregnant women. One of the tests performed to evaluate fetal health during pregnancy is the Nonstress Test (NST). Objective: To evaluate the effect of NST device noise level on stress parameters in primiparous pregnant women. Method: A randomized controlled, prospective study was conducted with 44 pregnant women in a State Hospital in Istanbul/Turkey between 01.02.2021 and 01.10.2021. Personal Information Form, Spielberger State Anxiety Inventory, Hillrom Welch Allyn Connex Spot Monitor, Gluco Dr Glucometer, Extech SL 400 Personal Noise Dosimeter, Sennheiser HD 450BT ANC Over-Ear Bluetooth Headset, Eppendorf Tube, Philips Avalon FM20 NST were used to collect data. A p value of \<.05 was considered significant in the statistical evaluation.

Outcome Measures

Primary Outcomes (2)

  • Does increasing the noise level of the NST device affect If salivary cortisol levels

    Data collection tool used to reach this outcome: Saliva cortisol was measured by a microplate reader with commercially available kit based on ELISA.

    01.02.2021-01.10.2021

  • Does increasing the noise level of the NST device affect If salivary ACTH levels

    Data collection tool used to reach this outcome: Saliva ACTH was measured by a microplate reader with commercially available kit based on ELISA.

Sampling MethodProbability Sample
Study Population

It was decided to make the minimum sample size required in the study by power analysis, taking into account the differences of the pre-test and post-test variables, which are the primary results. More than 2 groups analysis (ANOVA) test in repeated measurements in the calculation, effect size: 0.25, type 1 error rate (α)=0.05, power of the study (1- β) was 0.80 (Type II error= 0.20). Accordingly, the minimum number of samples to be reached was calculated as 40 in total, and the study was completed with 44 samples, taking into account the 10% risk of loss.

You may qualify if:

You may not qualify if:

  • Pregnant women whose contractions are detected during the NST procedure,
