Data Warning â–¸

Breast feeding history is obtained via self-report, so is vulnerable to recall bias concerning the timing of starting and/or stopping breast feeding. In addition, as the data is obtained via a survey, it is likely that missing data will need to be statistically addressed during analysis.

Please review the Known Issues & Pending Updates page for updates that may affect data use.

Instrument Details🔗
