ABSTRACT
Objective To explore the effect of maternal animal sourced food intake during pregnancy on neonate birth weight and provide scientific basis for guiding the reasonable diet intake in pregnant women and increasing neonate birth weight.Methods Data were derived from a cross-sectional project of "the prevalence and risk factors of birth defects in Shaanxi province",which were conducted in 30 counties in Shaanxi province from July to November in 2013.A stratified multistage random sampling method was used to select women who were pregnant between January 2010 and December 2013 for a random semi-quantitative food frequency questionnaire survey to collect the data on the frequency and amount of food consumption on animal protein sources and the data of newborns.Children aged 0-1 years and their mothers were selected as the study subjects.The generalized linear model was used to analyze the relationship between the neonate birth weight and maternal animal sourced food intake during pregnancy,and by using neonate birth weight as dependent variable,food intake frequency as independent variable,three adjustment models were established for stratified analysis.Results Totally 11 459 participants were involved in this study.The average birth weight of newborn was (3 279.9 ± 454.6) g,the average weekly intake of animal sourced foods was 4.00 times for egg,1.50 times for meat,3.00 times for dairy foods,0.50 times for fish and 5.00 times for overall animal sourced foods in pregnant women.Without stratification,three models shown that meat and overall animal sourced food intake had effects on neonate birth weight.After adjustment for gestational weeks,maternal age,social and demographic factors and others,meat intake increased by 1 time a week,the increase of neonate birth weight was about 5.26 (95% CI1.32-9.20) g,and the overall animal food increased by 1 times a week,the average neonate birth weight increased by 3.24 (95% CI1.09-5.39) g.Stratified analysis showed that meat and overall animal sourced food always had more influences on baby girls and those living in rural area.In the region classification,the overall animal sourced food intake had more influences on women living in northern area and Guanzhong area of Shaanxi,and meat intake had greater influence on women living in southern Shaanxi.And the influences were positive,the more animal sourced foods were taken,the greater the birth weight increased.Conclusion Animal sourced food intake during pregnancy would benefit the increase of neonate birth weight.It suggests that pregnant women should pay more attention to the intake of animal sourced food.
