Low Birth Weight Related Factors Affecting The Research

ObjectiveIn recent years, with the level of development of assisted reproductive technology and increased environmental degradation and food security situation, the impact of the increase in maternal adverse lifestyle and mental pressures and other factors, low birth weight children has increased every year. This study explores causes related influence factors of low birth weight, premature so as to provide the basis for seeking corresponding effective interventions.Subjects and MethodsThis topic selection of Dalian City in 2013 January to 2014 December in Dalian City Maternal and child health hospital obstetrics childbirth parturient woman as the object of study. In a questionnaire survey conducted research(all respondents are informed consent). The birth weight below 2500 g in pregnant women is set as the study group, and birth weight greater than or equal to 2500 g of pregnant women as control group, were the same questionnaire. Data input and statistics using the SPSS13.0software, qualitative variables using chi square test were used for univariate analysis,quantitative variables by using single factor variance analysis of single factor analysis,α=0.05; Using two classification logistic multivariate regression analysis regression,α=0.05. Analysis of cause of preterm related risk factors of low birth weight infants.ResultsThis study is to investigate the low birth weight infants(Study Group) and normal birth weight infants(control group) each 330 cases were recovered, Among them, 630 cases with complete with visitor data, the study group 324 cases, control group 306 cases. In study group, babies born in the average weight was 2.02 + 0.45Kg; 264 low birth weight premature infants, full-term low birth weight in 60 cases. Among them,preterm low birth weight for gestational age of 27 weeks minimum. The study group and the control group in the single factor analysis showed the neonatal birth condition:Study group the incidence of birth defects is higher than that of control group. The study group and the control group comparison showed that the high risk factors of premature birth weight infants is low. The study group and the control group in the single factor analysis showed: Pregnancy on pregnancy age, mother of births, multiple births, the mother with preterm history, history of cesarean section, abnormal placenta history,pregnancy induced hypertension history, the Department of internal medicine disease history, umbilical cord around the neck, around the body, polyhydramnios or oligohydramnios, amniotic fluid pollution, parents education level, mother’s occupation environment contact with harmful factors passive smoking, mother, pregnancy care times, father life emotion, computer time to contact the mother during pregnancy day,father every contact computer time and other factors, The study group and the control group which has statistical difference(P < 0.05). In the multivariate logistic regression analysis showed: The study group and the control group in twins or multiple pregnancy,occupation environment mother contact with harmful factors, maternal suffering from pregnancy induced hypertension, amniotic fluid pollution factor is statistically significant(P < 0.05).ConclusionsThe reason for premature low birth weight infants is very complex, and often work together.1. Single factor analysis showed: The main factors of low birth weight is Preterm birth. Second, pregnancy age, mother bore times, multiple pregnancy, the mother has a history of preterm labor, cesarean section history, history of placental abnormalities,history of Gestational hypertension and so on is cause of risk factors for low birth weight.2. By multivariate logistic regression analysis revealed: twins or multiple births,occupation environment mother contact with harmful factors, maternal suffering from pregnancy induced hypertension, amniotic fluid pollution and other factors may be the risk factors of premature and low birth weight infants.3. Low birth weight infants with risk of birth defects than normal birth weight infants high.
