Objective The objective of this study was to determine the impact of nausea and vomiting of pregnancy (NVP) and other determinants on generic and NVP-specific health-related quality of life (QOL) in the first trimester of pregnancy.Design Prospective study.Setting Centre Hospitalier Universitaire (CHU) Sainte-Justine or René-Laennec clinics, Montreal, Quebec, Canada.Population Pregnant women attending the clinics for their prenatal care from 2004 to 2006. Women were eligible if they were ‡18 years of age and £16 weeks of gestation at the time of their first prenatal visit.Methods After their first prenatal visit, women were asked to fill out a questionnaire covering maternal characteristics, presence and severity of NVP, and health-related QOL.Main outcome measures QOL was measured by the generic 12-item Short Form Health Survey v.1 (SF-12) and the NVP-specific Quality of Life for Nausea and Vomiting during Pregnancy.Results Of the 367 pregnant women included in the study, 78.5% of women reported NVP in the first trimester of pregnancy. Multivariable linear models showed that presence of NVP in the first trimester of pregnancy was significantly associated with a lower physical component summary scale (P < 0.0001) and mental component summary scale (P = 0.0066) of the SF-12 scores. More severe NVP (moderate versus mild: P = 0.0002; severe versus mild: P = 0.0177 as measured by the validated modified Pregnancy-Unique Quantification of Emesis and Nausea index), intensity of nausea symptoms reported on a visual analogue scale (P < 0.0001), and nonpharmacological methods used to ease NVP symptoms in the first trimester of pregnancy (P = 0.0059) were significantly associated with poorer NVPspecific QOL among women suffering from NVP.Conclusion These findings show that presence and severity of NVP have a negative impact on health-related QOL, which emphasises the importance of an optimal management of NVP.

Neonatal behavioral signs were frequently found in exposed newborns, but symptoms were transient and self-limited. Premature infants could be more susceptible to the effects of selective serotonin reuptake inhibitors and venlafaxine.

Background: Studies that contributed to the epidemiology of nausea and vomiting of pregnancy have reported conflicting findings, and often failed to account for all possible co-variables necessary to evaluate the multidimensional associations. The objectives of this study were to: 1) Estimate the prevalence and the severity of nausea and vomiting of pregnancy during the 1 st and the 2 nd trimester of pregnancy, and 2) Identify determinants of presence and severity of nausea and vomiting of pregnancy during the 1 st and 2 nd trimesters separately, with a special emphasis on the impact of race/ethnicity.
