title: Maternal pregnancy vomiting and offspring salt taste sensitivity and blood pressure.
abstract: The purpose of this study was to investigate the relationship between salt taste perception and blood pressure (BP) in normotensive adolescents as modified by maternal fluid losses during the first trimester of gestation. Seventy-two healthy adolescents (42 boys) aged between 9.0-21.1 years, recruited from the population-based RICARDIN study, were included. A maternal questionnaire about the duration of pregnancy, birth weight and vomiting or diarrhoea in the first trimester of gestation was collected. The sample was categorized into: "vomiter descendents", those whose mother reported significant vomiting in the first trimester of gestation and "non-vomiter descendents" the remaining. Height, weight, and standardised BP measurement were recorded. Salt gustatory performance was assessed using a behavioral sensitivity test to determine the lower NaCl gustatory threshold, and a behavioral discrimination test, measuring the ability to distinguish among different saline solutions. Salt taste sensitivity showed a significant correlation with systolic BP (SBP) in "vomiter descendents" ( r = -0.66; P =0.003), but not in "non-vomiter descendents". Adjusted by gender, and actual height and weight, salt sensitivity performance remained significantly related to SBP. An association between descendents' SBP and maternal vomiting during gestation exists, adding a new element of evidence to the "Barker hypothesis".
