Introduction: From a public health standpoint, the average weight of newborns is one of the main indicators of the quality of health care services received, reproductive health, safe motherhood, nutrition and intrauterine growth during pregnancy. The aim of this study is to investigate the relationship between the biological characteristics and the marital satisfaction of mothers who give birth to newborns with low birth weight (LBW) in the city of Chalus.
Method: This is a causal–comparative study, conducted in 2016 in which the mothers of 50 newborns with a birth weight of less than 2500 g and those of 50 newborns with an ideal / satisfactory weight of more than 3800 g were surveyed. The information was gathered with Afrooz Questionnaires for Biological, Cognitive, Psychological and Social traits of Mothers and Marital Satisfaction of Couples. The data collected from the questionnaires was analyzed with descriptive statistics and logistical regression using SPSS version 22.
Results: The results of this study showed that the frequency of newborns with LBW in Chalus was%3/7. The frequency of pregnant mothers with an age of less than 20 was%3/33 while those over 35 was%11, and%23/8 with consanguineous marriages. The analysis showed that of the maternal characteristics studied, Mather’s age and marital satisfaction had a statistically significant relationship with LBW in newborns.
Conclusion: This study demonstrated that certain biological and psychological maternal traits have a considerable impact on LBW in newborns, and can be further considered in programs aimed towards the prevention of LBW.
