This study was aimed to reveal that the usual cold or heat state was associated with hypertension and could be
a risk. We emailed educational personnel in D university to join this study and 182 subjects participated in from
March to December in 2016. The usual cold or heat diagnosis was conducted by two experts who had over 10 years
expertise. The blood pressure was measured from the subjected after 10 minute rest with Jawon medical device. The
hypertension was diagnosed by the guide of the Seventh Report of the Joint National Committee on Prevention,
Detection, Evaluation, and Treatment of High Blood Pressure. The frequency analysis was used in general
characteristics, Pearson’s Correlation Coefficient analysis was conducted in among continuous variables, and
chi-square test was also used between hypertension and cold or heat group. Logistic regression was analyzed to
generate the odds ratios (ORs) and 95% confidence interval (CI) for hypertension. The cold score was suggested to
have negative association with Body mass Index (BMI, -.374, p<.001), systolic blood pressure (-.333, p<.001), and
diastolic pressure (-.261, p<.001). The heat score was analyzed to have positive association with Body mass Index
(.413, p<.001), systolic blood pressure (.249, p<.001), and diastolic pressure (.156, p<.001). The distribution of the cold
group (35.1%) and non-cold group (64.9%) in hypertension was significantly different (p=0.18). The distribution of the
heat group (62.2%) and non-heat group (37.8%) was significantly different (p=0.27). The usual cold was associated with
decreased ORs (ORs 0.405, 95% CI=0.191-0.857), and usual heat was associated with increased ORs (ORs 2.327, 95%
CI=1.108-4.888). However, after adjusting body mass index, sex, and smoking, the association was not significantly
different. It is possible that usual cold or heat associate with hypertension. Further study is needed to show that
usual heat may be a independent risk factor for hypertension through follow up design. |
