Data from the iGrow study includes prenatal maternal perceived stressful life events and infant cortisol output. Variables also include covariates such as women’s prenatal substance use, time since the infant was last fed, and number of available cortisol samples. The dataset was contributed by Yu Chen and is hosted on Harvard Dataverse, with a last update recorded on 2026-05-28.
Use Cases
- Modeling the relationship between prenatal perceived stressful life events and infant cortisol output.
- Investigating the role of covariates like maternal substance use as potential confounders in stress-biology associations.
- Analyzing how factors like time since last feeding correlate with infant cortisol measurements.
Strengths
- Includes multiple covariate measures such as prenatal substance use and feeding timing, which can support controlled analyses.
- Dataset is hosted on Harvard Dataverse, a reputable academic repository.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment for large-scale analyses.
