Objectives Home blood pressure is theoretically ideal tool for longitudinal measurement during pregnancy. We previously reported that the home blood pressure was affected by environmental temperature and had stronger association with offspring’s birth weight than conventional blood pressure. In this study we compared morning and evening home blood pressure during pregnancy. Methods We used database from the BOSHI study which participated pregnant women from October 2006 to September 2011 at a maternity hospital in Miyagi Prefecture, Japan. The participants were asked to measure their own blood pressures every morning and if possible every evening at home while they were pregnant. A linear mixed model was used for analysis of the BP course throughout pregnancy. The SAS package (version 9.4) was used for the statistical analyses. Results Total 488 pregnant woman was included into the analysis. The average number of days home blood pressure measured was 77.9 days in the morning and 66.3 days in the evening. Home blood pressure values during pregnancy measured in the morning were a little but significantly higher than that measured in the evening (Δ = 0.9/2.6, P = 0.02/
