Objective To examine and compare dietary nutrients status,prenatal care,life style of mother of preterm /low birth weight (LBW) infants (preterm group) and full term infants (full term group) in two counties in Chongqing. Methods Interviews were conducted among the mother of 460 preterm/LBW infants and 460 full term infants by trained interviewers using questionnaires about maternal nutition,prenatal care and life style.Chi-square and analysis of variance (ANOVA) test were employed to test between-group differences in demographic characteristics,maternal nutition,prenatal care and life style. Results The proportions of mother during pregnacy taking folate,the proportion and and frequency of mother eating animal foods,milk and dairy products,fruits,and eating average amouts of animal foods for preterm/LBW group were all lower than the full term group.Such differences were statistically significant.The differences of mother during pregnancy taking calcium,vitamins for two groups were not statistically significant.While the differences of mother during pregnancy taking the amount of staples,the frequency of vegetables,eggs,beans and soy products weekly were not statistically significant.The frequency of prenatal care,the proportion of prenatal care in second-class medical institution,the weight of mother before delivery for preterm group were all lower than the full term group,WBC at childbirth for preterm group was higher than the full term group.Such differences were all statistically significant.No significant differences were observed in the proportions who took prenatal care in different levels of hospitals,who passived smoking,who with prenatal intercourse,who used electric blanket,who physical activity,and neutrocyte at childbirth. Conclusions The status of maternal nutition in pregnancy for preterm group is worse than the full term group,and the frequence of antenatal care for preterm group is less than the full term group.It is necessary to suggest for strengthing maternal nutition in pregnancy and maintaining regular antenatal examination for the decrease of reducing preterm /low birth weight infants.
