Improving Blood Pressure ControlNCT02701829
Taxi METERS: Measuring Effectiveness of Technology, Education, Referrals and Support
A study testing Health Fair + TECH [Text Messaging + Home Blood Pressure Monitoring] and Heal th Fair + TECH [Text Messaging + Home Blood Pressure Monitoring] + Social Network Support (SNS) in people with Improving Blood Pressure Control, run by Memorial Sloan Kettering Cancer Center at 1 site in United States.
Trial summary
In our past work it was found that many drivers had high blood pressure, and lifestyles that led to being overweight and not having cancer screenings performed. The investigators are now adding to the Health Fairs' usual program different ways of following up with drivers who attend our Health Fairs. Read more about this study

- Men only
- Healthy volunteers accepted
- Adult, Older adult
Who may be able to join
- Male
- 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}
- 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);
- Planning on remaining in NYC for at least 9 months (with no vacations or trips to exceed two months)

- Licensed taxi driver for at least 3 months;
- Speaks English, Spanish, Bengali, Urdu, or French;
- Owns a cell phone that can receive text messages and is willing to receive text messages for this study
Who cannot join
- 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.

About this study
In our past work it was found that many drivers had high blood pressure, and lifestyles that led to being overweight and not having cancer screenings performed. The investigators are now adding to the Health Fairs' usual program different ways of following up with drivers who attend our Health Fairs. The investigators are doing this because they want to find the best way to help drivers manage high blood pressure, and reduce cancer risk, by maintaining a healthy weight and increasing colorectal cancer screening. Health screenings will be conducted by trained personnel, and a physician or nurse will provide a health consult in person or over the phone (via MSK-issued phone/video/audio devices).
In the event that participants are unable to meet in person for biometric measurements, staff will accept their self-reported weight, blood pressure, and waist circumference over the phone. Staff may mail blood pressure machines (to participants who did not receive them at baseline), scales, and measuring tapes to participants to assist in the completion of self-reported biometric measures. Along with supplies, participants may also receive a letter asking for the confirmation of supply receipt.
- If critically abnormal values are identified during the health fair, under the advisement of the clinician, the driver may be escorted by trained staff directly to a health care facility for immediate medical follow-up

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
In our past work it was found that many drivers had high blood pressure, and lifestyles that led to being overweight and not having cancer screenings performed. The investigators are now adding to the Health Fairs' usual program different ways of following up with drivers who attend our Health Fairs.

Health screenings will be conducted by trained personnel, and a physician or nurse will provide a health consult in person or over the phone (via MSK-issued phone/video/audio devices).
In the event that participants are unable to meet in person for biometric measurements, staff will accept their self-reported weight, blood pressure, and waist circumference over the phone. Staff may mail blood pressure machines (to participants who did not receive them at baseline), scales, and measuring tapes to participants to assist in the completion of self-reported biometric measures.

Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
decrease in blood pressure levels (time frame: 9 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 30 Oct 2025.
