RESUMO
The impact of a hypertension awareness and educational program, BP DownShift, was evaluated among school bus drivers in a southern US state. At baseline (August 2007), blood pressure (BP) measurements, self-reported demographics, and hypertension awareness and management practices were collected from drivers who consented to participate in the study. Interventions included 4 educational mailings, installation of BP machines at all bus terminals, and access to free dietitian consultations and gym memberships. BP was evaluated using Department of Transportation guidelines. BP was remeasured and a survey was administered at follow-up (May 2008). At baseline, 208 drivers consented to the BP screening; 120 (58%) returned for a follow-up assessment. Most participants completing the study were female (73%) and African American (72%). Mean age was 50 years and mean body mass index was 32 kg/m(2); 52% of participants were obese. In all, 58% of participants reported a prior diagnosis of hypertension by a physician, and 63% reported taking antihypertensive medication. Both systolic and diastolic BP (SBP and DBP) were lower at follow-up (135/82 mmHg vs. 145/87 mmHg at baseline; P < 0.001, both comparisons); 42% had a reduction in SBP > 10 mmHg, and 44% had a reduction in DBP > 5 mmHg. At follow-up, 58% were controlled to BP < 140/90, compared to 38% at baseline (P < 0.001). At follow-up, an increased proportion of previously diagnosed drivers reported home BP monitoring, healthy diet, and regular exercise as components of hypertension self-management. The implementation of our hypertension education, self-management, and awareness program was associated with an improvement in BP control, which may positively impact commercial driver's license recertification as well as improve employee health.
