| Abstract
|
| [Objective] Preliminary study on the effects of seasons and Chinese solar terms on blood pressure in subjects with grade 1 hypertension, normal high blood pressure and normal blood pressure.[Methods] Ten subjects fulfilled the inclusion and exclusion criteria went into grade 1 hypertension group, normal high blood pressure group and normal blood pressure group separately in each group. Investigators requested subjects to record data of blood pressure in the whole year and corresponding seasons as well as Chinese solar terms. SPSS 17.0 software was used for statistical analysis.[Results] 1) The effects of seasons on blood pressure:Both systolic blood pressure (SBP) and diastolic blood pressure (DBP) in grade 1 hypertension group were rising significantly (P<0.05) in winter by comparison with autumn, while the data in spring were declining compared with winter (P<0.01). SBP was decreasing in summer by comparison with spring (P<0.05), and was increasing in autumn by comparison with summer (P<0.05). SBP in normal high blood pressure group was rising in winter than in autumn (P<0.01), declining in summer than in spring (P<0.01). In normal blood pressure group, all SBP and DBP in all seasons were not fluctuating statistically significant (P>0.05). 2) The effects of Chines solar terms on blood pressure:in grade 1 hypertension group, SBP was fluctuating significantly in the following periods:Shuangjiang to Lidong, Lidong to Xiaoxue, Dongzhi to Xiaohan, and Lichun to Yushui (P<0.05), DBP was fluctuating significantly in the following periods:Lidong to Xiaoxue, and Lichun to Yushui (P<0.05). In normal high blood pressure group, SBP was fluctuating in the period of Xiaohan to Dahan (P<0.05). Both SBP and DBP in normal blood pressure group were not statistically changed in all Chines solar terms changing periods (P>0.05).[Conclusion] Blood pressure are seasonal changed in both grade 1 hypertension and normal high blood pressure subjects, and the regular pattern is decreasing in spring, lower in summer, stable in autumn and higher in winter. Fluctuations of blood pressure in grade 1 hypertension group are obvious in winter and spring. The study indicated that grade 1 hypertension patients should pay more attention to blood pressure management on Lidong, Xiaoxue, Xiaohan and Yushui. |
