Abstract:
Objective To investigate the associations between preconception dietary patterns(DPs)among Chinese women of childbearing age and neonatal birth weight.Methods The subjects selected for the questionnaire survey and follow-up were women of childbearing age who underwent prenatal eugenic examination at Jiang'an Maternal and Child Health Hospi-tal.Dietary intake information was collected using a semi-quantitative food frequency questionnaire,dietary patterns were extrac-ted by principal component analysis,and the relationship between DPs and birth weight was analyzed by modified Poisson re-gression or linear regression models.Results The final analysis of 221 maternal and infant pairs showed that women who fol-lowed the"nuts-poultry"pattern,one of the four dietary patterns,had a lower risk of delivering large for gestational age(LGA)infants(RR:0.25;95％CI:0.08-0.79),which was more pronounced in those who delivered male infants(RR:0.14;95％CI:0.03-0.72).Conclusion The risk of having LGA newborn is decreased in woman who takes a preconception dietary pattern characterized by nuts and poultry,which is more pronounced in those delivering male infants.Females of childbearing age should maintain good dietary habits before conception to ensure proper growth and development of the fetus and reduce the risk of ad-verse birth outcomes.
