Hypertension

A study was performed relating neonatal blood-pressure level to neonatal taste responsiveness (Zinner et al. [29]). To assess salt taste responsiveness, infants 2 to 4 days old were offered 3 solutions via nipple cannulas containing (i) water, (ii) water + 0.1 molar salt, and (iii) water + 0.3 molar salt. Infant blood pressure was measured separately with a Physiometrics machine at 2€“4 days of age. A comparison was made between the mean number of sucks per burst of sucking (MSB) on (water + 0.3 molar salt) minus the MSB on water alone = Δ MSB. If Δ MSB ‰¤ ˆ’ 10, it was considered an aversive response; if Δ MSB > 0, it was considered a preferential response; otherwise, it was considered a neutral response. For the purposes of this question, the neutral response infants were eliminated and we compare the distribution of diastolic blood pressure between the aversive and preferential response infants. The results are given in Table 10.46.
