Clinical Trial Summary

This project is a single blind cluster randomized controlled trial with a purpose of assessing the effectiveness of a comprehensive tertiary interventions (before pregnancy, during pregnancy and after delivery) on the incidence and the clinical outcomes of birth defects in a preparing-for-pregancy population in Shanghai. The preconception intervention is focused on identifying individuals whose red blood cell folate level is below recommended level for preventing neural tube defects (400ng/ml) or with elevated homocysteine level (over th 80th percentiles, 6.8 µmol/L) , and modifying their folate deficiency status to normal before pregnancy.

Outcome

Type Measure Description Time frame Safety issue
Primary Incidence of total fetal birth defects found during the second trimester, still birth, and neontal birth defects identified after delivery This is a composite outcome: the total number of fetus defects detected by Down's syndrome screenings, NT examinations and Ultrasound image examinations during the second trimester, stillbirth, and the number of birth defects after delivery diagnosed by clinical team.
(Defects are classified in consistent with our birth defect monitoring policy, which have 24 types of defects: Anencephalus; Spina bifida; Encephalocele; Congenital Hydrocephalus; Cleft Palate; Cleft Lip; Cleft Lip with Cleft Palate; Microtia (including Anotia); Deformity of external ear(s) (except Microtia and Anotia); Esophageal atresia or stenosis; Anorectal atresia (including Congenital Anorectal Malformations); Hypospadia; Ectopocystis; Pes Equinovarus; Polydactylism; Syndactylia; Limb shortening; Congenital Diaphragmatic Hernia; Pcromphalus; Celoschisis; Conjoined Twins; Trisomy 21 syndrome; Congenital heart disease; Others. )
From the confirmation of pregnant to 28 days after birth
Secondary Incidence rate of total abortion because of the affected congenital defects Reasons of abortion are recorded From the confirmation of pregnant to the 28th gestational week
Secondary Incidence of death or severe organ dysfunctions Severe organ dysfunctions were defined based on specialty clinical examinaitons From birth to 6 months after delivery ( can be expanding to the end of the 7th month)
Secondary Extra medical cost that relates to affecting any birth defects during pregnancy and after birth Additional medical cost that exceeds normal pregnancies and children within one year old From confirmation of pregnancy to one year old after birth
Secondary incidence of congenital heart defect congenital heart defects diagnosed during pregnancy (ultrasound) and after birth( Echocardiography). (Definition see Zhao et al. Lancet 2014) from conception to one year old
Secondary Total pregnancy loss artificial abortions without any medical reasons were exluded from conception to 28 gestational weeks
