Description
For sample children under age 18, NAUSEAYR reports responses to the question, "During the past 12 months, has [sample child] had ... Nausea and/or vomiting?"
For 1998 forward, INTESTILL2WK reports whether sample adults and sample children had a stomach or intestinal illness with vomiting or diarrhea that started during the past two weeks. In 1999, sample adults with an affirmative answer in INTESTILL2WK were asked whether they saw a doctor for this condition (INTESTMD2WK).
