Abstract
BACKGROUND: Sudden infant death syndrome is the third leading cause of infant death in the first year of life and is one of the most important health problems around the world. The exact etiology of this phenomenon is not clear yet, but some risk factors, especially prone sleep positions, have been described. Fortunately, by modifying some environmental factors, the SIDS incidence might be decreased. Mothers' and caregivers' knowledge about this neglected event could be an important factor in determining SIDS prevalence. MATERIALS AND METHODS: This cross-sectional study was conducted in the pediatric and neonatal specialty clinic of Bahar Shahroud Hospital in 2020. Five hundred and twenty-seven pregnant women of reproductive age (18 to 45 years) were included in the study. Assessment of mothers' knowledge was done using a sudden infant death syndrome risk questionnaire. Statistical analysis of data was performed using independent t-test, Chi-square, and logistic regression. RESULTS: The number of 527 pregnant women of childbearing age participated in our study. 81.9% were under 35 years old. According to the study, factors such as maternal age, mother's level of education, number of pregnancies, and history of previous infant death syndrome had a significant relationship with the mother's level of knowledge about infant death syndrome. The findings showed that the mother's age is over 35 years old during pregnancy (CI: 0.95-0.46-OR: 1.53) and the level of education under a diploma (CI: 3.13-1.6: 06, OR: 1.86), and increasing parity is associated with a lower level of knowledge about infant death syndrome. CONCLUSION: According to mothers' lack of knowledge about SIDS and the availability of simple and cost-effective methods to prevent SIDS, improving mothers' knowledge about this important event in pregnancy and postpartum, educational sessions are crucial.
