Introduction: Children are more risk‑prone group of the population and low birth
weight (LBW) is the leading cause of newborns’ mortality and morbidity. LBW is defined
as child’s birth weight lower than 2500 g. Many maternal and fetal factors are determined
as risk factors of LBW. This study tries to detect related factors to LBW and effect of them
on children’s growth pattern up to sixth month of life in Health centers of Urmia city, Iran.
Materials and Methods: A cross‑sectional study was carried out in Urmia city using
registered data from mothers` documents. All related data such age and weight of infants,
mothers’ age, gestational age (GA) at the time of delivery, time gap between two pregnancies,
past history of abortion, prenatal care history, systemic and underlying diseases, hemoglobin
of mothers during pregnancy, and pattern of infant’s growth up to sixth month of age were
registered in a questionnaire. All registered data were transferred to SPSS 15 software and
analyzed. Results: Mean ± SD of birth weight was 3071 ± 625.66 g. There was a significant
relationship between birth weight and mother’s age (P < 0.001) and weight (P < 0.001).
Children of mothers younger than 18 years had much birth weights. There was a
significant relationship between birth weight and GA during delivery (P < 0.001). Children
of preterm labor had lower birth weights. In twins, LBW was more prevalent (P < 0.001).
Conclusion: Our results show that LBW is related to multiple causes and that most of
them are preventable with educational programs and also strict and regular prenatal care.
Decreasing incidence of LBW children can be achieved by cooperation between different
parts of health and clinical systems.
