Abstract

Abstract: Objectives: The association of temperature maintenance with blood pressure (BP) has not been studied and the association of temperature with season-related BP was not being well understood. The present study aims to be further aware of season-related BP variation in Chinese adults. Methods: We used decoded data from adults who visited the hospital for health examination from January 2008 to November 2013. Multivariate regression models were used to analyses the association between outdoor temperature and BP. Results: The analysis included 438, 811 adults. Larger change of BP accompanied with unit change of average outdoor temperature among outpatient than inpatient patients. The association of temperature with BP was stronger in normotensives than that in hypertensives. Compared with temperature variation, the impact of temperature maintenance on BP was smaller. These associations were stronger in men, older individuals. Conclusions: Temperature was strongly inversely associated with BP in Chinese adults. Temperature maintenance was mildly associated with BP compared to temperature variance. Seasonal temperature variation should be considered when screening for hypertension.
