Effects of Smartphone Addiction to Fetal Parameters in Pregnancy

This prospective cohort study investigates the relationship between smartphone addiction and fetal health parameters at the third trimester of pregnancy. Pregnant women will be evaluated for smartphone addiction, and fetal heart rate, uterine artery blood flow indices (Resistive Index, Systolic/Diastolic ratio), and birth weight will be measured. The hypothesis is that smartphone addiction may negatively affect fetal outcomes, leading to higher fetal heart rate, impaired uterine artery blood flow, and lower birth weight. Although no direct studies have examined smartphone addiction and these fetal parameters together, related evidence suggests possible adverse effects of mobile phone exposure on oxidative stress, infant birth weight, fetal heart rate variability, and anthropometric measures. This study is among the first to specifically link smartphone addiction with maternal-fetal outcomes, offering new insights into environmental risk factors during late pregnancy. The findings aim to provide healthcare professionals with evidence based guidance for counseling pregnant women on safe smartphone use to protect maternal and fetal health.
