| Abstract
|
| [Objective] Preliminary study on the changing patterns of weather factors, such as temperature, relative humidity, weather conditions on blood pressure in subjects with grade 1 hypertension, normal high blood pressure and normal blood pressure.[Methods] Thirty subjects fulfilled the inclusion and exclusion criteria went into grade 1 hypertension group, normal high blood pressure group and normal blood pressure group separately at the same period (ten in each). Investigators requested subjects to record data of blood pressure in the whole year and corresponding temperature, relative humidity, weather conditions in Tianjin. SPSS 19.0 software was used for statistical analysis.[Results] Daily mean systolic blood pressure (SBP) and diastolic blood pressure (DBP) in grade 1 hypertension group, as well as daily mean SBP in normal high blood pressure group were in negative correlation with average temperature in five days, average daily temperature and relative humidity separately (r<-0.5,P<0.05). SBP in the morning in both grade 1 hypertension and normal high blood pressure were in highest correlation with average temperature in five days, average daily temperature and relative humidity separately (r<-0.6, P<0.01) compared with other measurement time points. SBP and DBP in grade 1 hypertension group, as well as SBPs in normal high blood pressure group were higher in smog days (P<0.05), lower in rainy days (P<0.05).[Conclusion] Both grade 1 hypertension and normal high blood pressure groups are influenced by weather factors obviously, and both should be monitored in the morning. |
