Abstract
OBJECTIVE: The present study aimed to analyze the association of 2-year changes in BMI and waist circumference with changes in blood pressure (BP) in a randomized sample of community-dwelling adults. METHODS: A sample of 331 middle-aged and older adults (mean age of 59.6 ± 17.3 years) was randomly selected. Measurements of SBP and DBP, BMI, and waist circumference were collected at baseline and after 2-year follow-up. Chronological age, sex, socioeconomic status, ethnicity, and self-reported medical diagnosis and use of medication for hypertension, diabetes, and high low-density lipoprotein-cholesterol were covariates. Multiple linear regression models were adopted for statistical analysis. RESULTS: SBP was positively associated with BMI (β = 0.48, P = 0.013) and waist circumference (β = 0.21, P = 0.005) at baseline and only with waist circumference at follow-up (β = 0.20, P = 0.007). DBP was positively associated with BMI (β = 0.31, P = 0.009) and waist circumference (β = 0.12, P = 0.006) values at baseline and at follow-up (BMI β = 0.42, P = 0.001; waist circumference β = 0.18, P = 0.001). Only the 2-year changes in waist circumference were associated to changes in SBP (β = 0.33, P = 0.013), regardless of confounding factors and BMI. CONCLUSION: It is suggested that waist circumference is the main factor for control over the time in strategies focused on BP management in adult population.
