1192 Medico-legal Update, July-September 2020, Vol.20, No. 3 Association of birth Spacing with birth weight in Baghdad City Buthaina Ateyah Rashid 1 ; Shaymaa Hadi Najm 2 ; Aws Azmi Shakir 1 1 M.Sc Community Health Technology College of Health and Medical Technology-Baghdad, Middle Technical University, 2 M.Sc Community Health Technology Institute of Medical Technology-Baghdad, Middle Technical University, Iraq Abstract Background: Birth spacing might infuence infantile under nutrition through its association with preterm births and low birth weight. If a pregnancy occurs too soon after the previous birth, the mother may not have recovered her nutritional status, which can contribute to preterm birth and low birth weight. Birth spacing allows women to recover and be healthy for their next pregnancy. Objectives: To determining the effect of birth spacing with birth weight, also to study the factors effecting birth spacing interval in a sample of women in Baghdad city. Materials and methods: The study design was descriptive study (cross sectional). Which included 100 women collected from Mohammad-Baker-Al-Hakim Hospital in Shua’la city in Baghdad, during the period from 10 th October 2017 till 10 th March 2018 during data collection, the questionnaire from each woman was done. Results: This study clarifed that the highest percentage of women (46%) had a birth interval (>24) months and (26%) them had a birth interval of (8-12) month. while, lower percentage of women (12%) had a birth interval of (13-18) months. The highest percentage of birth babies of (3.2Kg) and more than (3.2Kg) (51.19%) had a birth interval of (>24) months, while, highest percentage of less than (3.2Kg), (50%) had birth intervals of (8-12) months. Conclusions: The highest rate of women had a birth interval of (>24) months with birth interval of (8-12) months, had a birth interval of (13-18) months. Birth interval was longer in mother of breast feeding. The highest rate of birth space interval was among age group (26-30) years. The highest rate of birth weight babies had birth intervals of (>24) months with birth intervals of (8-12) months. Keywords: Birth, Spacing, Birth Weight, Pregnant. Introduction Birth spacing had been made by the International Organizations based on the information that was available several years ago. While publications by the World Health organizations (WHO) [1] and other international organizations recommend waiting at least 2-3 years between pregnancies to reduce infant and child mortality, and also to beneft maternal health [2] . Several studies have reported greater risks of the adverse pregnancy outcomes low birth weight and small- for-gestational-age (SGA) after short pregnancy intervals [1] . Some investigators have attributed the higher risk of poor pregnancy outcomes to the associated factors rather than causally relations of short inter pregnancy intervals, such as maternal socio-demographic characteristics and lifestyle [3,4] . Foliate depletion, in particular, has been proposed as the nutritional factor that contributes most to the risk of fetal growth restriction [5] . As a consequence, their offspring may be at higher risk of intrauterine growth restriction and low birth weight [6,7] . Data on date of delivery, infant gender, birth weight, and gestational age (based on ultrasound or, if that measurement was not available <10% of cases, on the timing of the last menstrual period as recorded by the obstetric
