Background: Premature birth is the main cause of neonatal mortality and long-term
complications, which imposes heavy financial and psychological burdens on the
family and society; therefore, it is important to recognize the factors affecting it.
Objective: The aim of this study was to determine the relationship between
socioeconomic status, psychosocial factors, and food insecurity with preterm
Materials and Methods: This longitudinal study was conducted on 674 pregnant
women at 24-28 wk of gestation who met the inclusion criteria. The subjects were
selected using cluster sampling. The pregnant women filled out total questionnaires
of study and they followed up until delivery and the data about the newborn was
collected after delivery. The data collection tools included questionnaires for
evaluating socioeconomic status, psychosocial factors, and food insecurity.
Results: The prevalence of preterm delivery was 7.7%, and socioeconomic factors
were not associated with preterm labor. Among the intermediary factors, social
health, food insecurity, stress, and prenatal care had a significant relationship with
preterm labor. The prevalence rates of preterm delivery in cases with food
insecurity, stress, and inadequate prenatal care were 2, 9.1 and 13.2 times higher
than those who had food security, did not experience stress, and received adequate
care during pregnancy.
Conclusion: Preterm labor is a relatively common problem in which intermediary
social determinants of health can play an important role. Considering the limited
studies on this issue, the results of this study can lay the foundation for future
