Abstract

LOW BIRTH WEIGHT (LWB) is defined by WHO as infants who weigh less than 2500 gm at birth. ln the world 20 million (16% of an births) LWB babies born each year, and accounts for up to 70% of neonatal deaths in some countries. An estimate of 5% LBW was announced for Iran by WHO in 1995. We sought to determined the frequency of LWB and some related factors in a group of lranain patiant, therefore a cross sectional study was conducted, intering 4000 delivery records of liveborn in the hospitals of Tehran University, in 1999.The frequency rate of LBW was 9.2% (369 cases), in univariate analysis, there was significant association between LBW and: PRETERM LABOR, PREMATURE RUPTURE OF MEMBRANEs (PROM), oligohydraminus, placental abruption, preeclampsia, primigravidity, twines or more fetuses and femal infants, (p<0/05). In our study 75.1% of LBW of infant was born preterm, compare to 24% full term infants (P=0.0001).In multivariate analysis based on logistic regression, PRETERM LABOR was the most important risk factor for LBW (OR =9.39 P=0.00001) Other significant risk factors included: PREMATURE RUPTURE OF MEMBRANEs (OR = 2.29 P= 0.00001), Oligohydraminus (OR = 1.9 P = 0.0396), Placental abruption (OR =2.01 P=0.0048), Primigravidity(OR = 2.05 P=0.00001) and twines or more fetuses (OR = 1.66, P= 0.0035).The maternal high risk ages (<20 and ≥35 years) was not a risk factor for LBW (OR =0.66 P =0.0145). According to our findings, it seems that the frequecy of LBW in Iran is nearly at an acceptable level, since the population or the study was selected from referral hospitals of Tehran, and preterm later seems to be the most important risk factor, though other factors are involve.
