The ReACH Pregnancy and Delivery Qualitative Harmonization Protocol was performed using the study questionnaires and data dictionaries encompassing the pregnancy and delivery assessments from 24 studies. This harmonization protocol includes 86 variables targeting mothers, fathers, and children.
The ReACH Pregnancy and Delivery Qualitative DataSchema covers information on:
* Mothers' socio-demographic and economic characteristics

* Mothers' reproductive history
* Mothers' disease history (diabetes, hypertension) and during pregnancy (gestational diabetes, gestational hypertension, preeclampsia)
* Mothers' depression and anxiety
* Mothers' medication and supplement intake
* Mothers' use of medically assisted reproduction and IVF
* Mothers' physical measures before and during pregnancy
* Fathers' socio-demographic and economic characteristics
* Fathers' smoking during pregnancy
* Fathers' depression and anxiety
* Children's socio-demographic characteristics
* Children's physical measures and assessments
* Children's disease (congenital malformations, cerebral palsy)
* Delivery and birth information and outcomes
Harmonization
- Complete - study-specific variable is the same as DataSchema variable (status detail = identical) or needs transformation to generate DataSchema variable (status detail = compatible)
- Partial - categorical study-specific variable (status detail = proximate) or other types (status detail = tentative) could generate DataSchema variable but with loss of information
- Impossible - study does not collect DataSchema variable (status detail = unavailable) or cannot be used to generate DataSchema variable (status detail = incompatible)
- Undetermined - harmonization status not determined
- Not Applicable - harmonization status is not relevant
