Objective To study the change trend of blood pressure among rural adults in Shanxi province from 2002 to 2019, and to provide evidence for the prevention and control of hypertension in the population.
Methods The study included 1 095 rural adult residents (≥ 18 years) with normal blood pressure at baseline in four counties of Shanxi province as part of the Provincial Nutrition and Chronic Diseases Household Cohort Study, which began in 2002. Data were collected from participants′ blood pressure measurements in 2015 and 2019, and changes in participants′ blood pressure between 2002 and 2019 were analyzed.
Results Among the participants, systolic and diastolic blood pressure (both in mm Hg) showed a significant increasing trend during the period (both P < 0.05). Compared to 122.9 ± 10.4 in 2002, systolic blood pressure increased by 14.8 to 137.7 ± 18.8 in 2015 and by 15.8 to 138.7 ± 18.1 in 2019, with an increase percentage of 12.0% and 12. 9%; while compared to 72.6 ± 6.9 in 2002, diastolic blood pressure increased by 7.3 to 79.9 ± 10.9 in 2015 and by 7.5 to 80.1 ± 10.9 in 2019, with increase percentages of 10.1% and 10.3%, respectively.
