Abstract:
Objective:To investigate the relationship between changes in waist circumference, body weight, and blood pressure change in a high cardiovascular risk population and to provide a theoretical basis and reference for the prevention and treatment of hypertension and cardiovascular disease.Methods:A total of 12 931 patients with a high risk of cardiovascular disease participating in the follow-up survey in 2016 were selected as the study subjects, and their long-term follow-up data from 2017 to 2019 were included in the analysis. Statistical analysis was performed using a t-test, χ2 test, and generalized estimation equation (GEE). Results:Increased waist circumference, body weight, and BMI were associated with a higher risk of elevated blood pressure in people at high risk of cardiovascular disease. Waist circumference, weight, and BMI were reduced when blood pressure levels were lower. SBP and DBP increased by 0.200 (95% CI: 0.164-0.236) mmHg and 0.085 (95% CI: 0.066-0.105) mmHg for each 1 cm increase of waist circumference. SBP increased by 0.355 (95% CI: 0.289-0.421) mmHg and DBP increased by 0.182 (95% CI: 0.144-0.220) mmHg for each 1 kg increase in body weight. For each 1 kg/m 2 increase in BMI, SBP increased by 1.100 (95% CI: 1.194-1.258) mmHg, and DBP increased by 0.365 (95% CI: 0.273-0.456) mmHg. Compared with urban residents, SBP changes more with waist circumference and body weight, and DBP changes more with waist circumference in high-risk cardiovascular disease groups (all P for interaction <0.05). SBP with waist circumference and BMI and DBP with BMI was greater in participants without hypertension than in those with hypertension (all P for interaction <0.05). Conclusion:There is a positive linear correlation between the changes in waist circumference, body weight, and BMI and the changes in blood pressure in a high-risk cardiovascular disease population.
