What is the purpose of this trial?

This trial aims to help taxi drivers manage high blood pressure and reduce cancer risk by promoting healthy weight and increasing cancer screenings. Participants will attend health fairs and may receive text messages and home blood pressure monitoring devices. Some will also get extra support from family or friends to encourage healthy habits. This trial could suit male taxi drivers with high blood pressure who have been licensed for at least three months in NYC. Participants should be ready to stay in NYC for the next nine months and have a cell phone for receiving texts.

As an unphased trial, this study offers a unique opportunity to contribute to research that could improve health outcomes for taxi drivers.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. It seems focused on monitoring and managing blood pressure rather than changing existing treatments.

Is there any evidence suggesting that this trial's treatments are likely to be safe?

Research shows that using text messages along with home blood pressure monitoring safely aids in managing blood pressure. Studies have found that text messages increase involvement, prompting more frequent checks and sharing of blood pressure readings. This method has been linked to better blood pressure control and earlier diagnoses of high blood pressure, facilitating quicker management of the condition.

When social network support is added to text messaging and home monitoring, research also shows it is safe and effective. Digital tools like these can improve blood pressure, especially for those with limited access to healthcare. This approach encourages adherence to treatment plans and has improved quality of life.

Overall, these methods are well-tolerated, with no major reports of negative effects. They leverage everyday technology and social support to help people manage their blood pressure safely and effectively. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Researchers are excited about these interventions for blood pressure control because they incorporate innovative technology and social support, which are not standard features in most current treatments. Unlike traditional methods that primarily rely on medication and regular doctor visits, these interventions use text messaging and home blood pressure monitoring to engage patients actively in managing their health. Additionally, the inclusion of social network support distinguishes one of the interventions by involving family and peers to encourage healthy behaviors, which could enhance motivation and adherence to blood pressure management. This multifaceted approach aims to empower individuals to take control of their health in a more interactive and supportive way.

What evidence suggests that this trial's treatments could be effective for blood pressure control?

This trial will compare different health support interventions for blood pressure control. One treatment arm uses text messages and home blood pressure monitoring, which research has shown can help manage high blood pressure. Studies found that sending text reminders to check blood pressure helps people maintain control, with over 64% of participants seeing improvements. Another arm in this trial adds social network support, where friends or family encourage healthy habits. However, some research suggests that support from others alone might not significantly aid blood pressure control. Overall, combining text messages and home monitoring appears promising for effectively managing blood pressure. ^{2 6 7 8 9}

Are You a Good Fit for This Trial?

This trial is for male taxi drivers over 19 years old in NYC with high blood pressure, who plan to stay in the city for at least 9 months. They must have a cell phone capable of receiving texts and speak English, Spanish, Bengali, Urdu, or French. Part-time drivers and those with cardiovascular diseases other than hypertension are excluded.

Inclusion Criteria

Hypertensive-level readings over three weeks, with at least two of three elevated BP readings (systolic ≥140 and/or diastolic ≥90); OR One hypertensive crisis readings (systolic ≥165 and/or diastolic ≥100) {eligible for the study without having to return for second or third readings} OR have a known diagnosis of hypertension and have elevated values at one reading {eligible for the study without having to return for second or third readings}

You can speak English, Spanish, Bengali, Urdu, or French.

Over 19 years of age (we are selecting participants older than three years past the legal driving age of 16, as younger drivers tend to change jobs more often)

Exclusion Criteria

Part-time driver (drives fewer than 35 hours per week). Although it is highly unlikely for NYC taxi drivers to work for multiple garages at study baseline, drivers may switch jobs and/or their garage base affiliation while participating in this study. New jobs and/or garage base affiliations will be tracked during follow-up assessments and noted for potential limitations with study retention and intervention contamination. Drivers will be allowed to continue the study even if they are no longer working with the initial garage base.

You have or had heart problems such as coronary artery disease, angina or aortic stenosis. High blood pressure is not included.
