BACKGROUND: The association between blood pressure (BP) control and incident diabetes mellitus remains unknown. We aim to investigate the association between degree of time-averaged on-treatment systolic blood pressure (SBP) control and incident diabetes mellitus in hypertensive adults. METHODS AND RESULTS: A total of 14 978 adults with hypertension without diabetes mellitus at baseline were included from the CSPPT (China Stroke Primary Prevention Trial). Participants were randomized double-masked to daily enalapril 10 mg and folic acid 0.8 mg or enalapril 10 mg alone. BP measurements were taken every 3 months after randomization. The primary outcome was incident diabetes mellitus, defined as physician-diagnosed diabetes mellitus, or use of glucose-lowering drugs during follow-up, or fasting glucose ≥126 mg/dL at the exit visit. Over a median of 4.5 years, a significantly higher risk of incident diabetes mellitus was found in participants with time-averaged on-treatment SBP 130 to <140 mm Hg (10.3% versus 7.4%; odds ratio [OR], 1.37; 95% CI, 1.15‒1.64), compared with those with SBP 120 to <130 mm Hg. Moreover, the risk of incident diabetes mellitus increased by 24% (OR, 1.24; 95% CI, 1.00‒1.53) and the incidence of regression to normal fasting glucose (<100 mg/dL) decreased by 29% (OR, 0.71; 95% CI, 0.57‒0.89) in participants with intermediate BP control (SBP/dias-tolic blood pressure, 130 to <140 and/or 80 to <90 mm Hg), compared with those with a tight BP control of <130/<80 mm Hg. Similar results were found when the time-averaged BP were calculated using the BP measurements during the first 6-or 24-month treatment period, or in the analysis using propensity scores. CONCLUSIONS: In this non-diabetic, hypertensive population, SBP control in the range of 120 to <130 mm Hg, compared with the 130 to <140 mm Hg, was associated with a lower risk of incident diabetes mellitus.
