Objective To investigate the status of folic acid(FA) supplementation and determinants of its use in pregnant Chinese women.Methods In this cross-sectional study,questionnaires were used to collect information of participants and FA supplementation.Women were recruited between 6 and 12 weeks postpartum in Tianjin,China,between July 2015 and July 2016.Results A total of 1,921 women were recruited in the study.Approximately 93.1% of the study participants used FA,while 14.4% of the women taking FA from three months prior to preconception to three months post-conception.Women who took FA for three months prior to preconception through at least three months into their pregnancy were more likely to be between 30 and 34 years old(OR=2.91,95% CI:1.15,7.33),employed(OR=2.07,95% CI:1.17,3.67),primigravida(OR=5.20,95% CI:3.02,8.96),married to spouses with an intermediate education level(OR=2.92,95% CI:1.45,5.89),and earn a high family income(OR=3.19,95% CI:1.57,6.49).Conclusion The prevalence of periconceptional FA intake was far below the requirements of the National Health and Family Planning Commission of China;therefore,knowledge of FA supplementation should be strengthened among women who are or planning to become pregnant.
Objective To investigate the status of folic acid (FA) supplementation and determinants of its use in pregnant Chinese women. Methods In this cross-sectional study, questionnaires were used to collect information of participants and FA supplementation. Women were recruited between 6 and 12 weeks postpartum in Tianjin, China, between July 2015 and July 2016. Results A total of 1,921 women were recruited in the study. Appximately 93.1% of the study participants used FA, while 14.4% of the women taking FA from three months prior to preconception to three months post-conception. Women who took FA for three months prior to preconception through at least three months into their pregnancy were more likely to be between 30 and 34 years old (OR = 2.91, 95% CI: 1.15, 7.33), employed (OR = 2.07, 95% CI: 1.17, 3.67), primigravida (OR = 5.20,95% CI: 3.02,8.96), married to spouses with an intermediate education level , and earn a high family income (OR = 3.19, 95% CI: 1.57, 6.49) .Conclusion The prevalence of periconceptional FA intake was far below the requirements of the National Health and Family Planning Commission of China; therefore, knowledge of FA supplementation should be strengthened among women who are or planning to become pregnant.
