Description: The purpose of this epidemiologic study was to increase the scientific base of knowledge about nausea and vomiting during pregnancy using a prospective cohort design. The specific objectives were to: (1) determine the incidence of nausea and vomiting during pregnancy in the study sample, (2) determine the risk factors for the development of nausea and vomiting during pregnancy, (3) identify which interventions women use for the relief of nausea and vomiting during pregnancy, and (4) identify which treatments women report as most and least effective in relieving nausea and vomiting during pregnancy.

One hundred-sixty pregnant women recruited from a Health Maintenance Organization in the Buffalo, New York area were included in the sample. The participants were predominantly white, married, and well educated. Data were collected during 3 structured telephone interviews which were conducted within 2 weeks after the initial prenatal appointment, at 16 weeks gestation, and after delivery.

In this study, incidence of nausea during pregnancy was 67%, while incidence of vomiting during pregnancy was 32%. Four significant risk factors for nausea during pregnancy were identified: (1) past history of nausea during pregnancy, (2) food aversions, (3) food cravings, and (4) increased salivation. Risk factors were the same for vomiting during pregnancy, except that increased salivation was not significant. Unconditional logistic regression equations controlling for age and parity confirmed the significance of these risk factors.

Analyses of the use of relief measures for nausea and vomiting in pregnancy, together with their perceived efficacy, revealed that the women in this sample used a wide variety of interventions to relieve nausea and vomiting. Dietary modifications comprised the most frequently used interventions. Eating small, frequent meals was the relief measure cited by the largest proportion of women. Many women reported eating or avoiding specific foods/drinks to relieve nausea and vomiting. Interventions unrelated to diet were also reported, the most frequently mentioned being getting more rest.

his research provides nurses with specific information about women's experiences with nausea and vomiting during pregnancy. Study results can be used as a database to design educational interventions for pregnant women. Further, findings have implications for the direction of future research.
