Variables
-
The objective of the 36 Months Harmonization Protocol was to define a list of core variables prospectively to be collected by three of the four mother and child randomized controlled trials to address the research aims of the HeLTI Initiative.
- Version
- 1.0
- Approach
- Prospective
- Type
- Quantitative
- Procedures
- Harmonized data is generated locally by studies (with the collaboration of the harmonization team).
- Participant Inclusion
- HeLTI participating children from three out of the four studies (no data collection at this timepoint in South Africa)
- Infrastructure
- Harmonized data must remain on study servers, but federated data analysis can be achieved
Information Content
The HeLTI 36 Months harmonized dataset includes information about:
- Lifestyle and behaviours (nutrition, sleep, physical activity, screen time)
- Chemical exposure (passive smoking exposure)
- Preschool life (child care)
- Symptoms and diseases
- Medication and supplements
- Death (cause of death)
- Adverse events (hospitalizations, birth defects, disability/incapacity, life-threatening conditions, child protective services involvement)
- Physical measures and assessments (height, weight, head circumference, mid-upper arm circumference, abdominal circumference, blood pressure)
- Administrative information

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
