Relatively Healthy Male Veterans Observed Over Time to See What Types of Diseases Develop (ACTIVE Health)

January 29, 2021 updated by: VA Office of Research and Development

CSP #499A - Selenium and Vitamin E Cancer Prevention Trial - COHORT

The purpose of this study is to gather a mixed racial group of relatively healthy male Veterans (for example, White, African-American, and Hispanic), who are at least 50 years of age. These men will be followed to see what types of diseases they develop and to determine if racial differences in lifestyle, blood test results, or genes are related to the types of diseases that are found. Diseases of particular interest are prostate cancer, other cancers, cardiovascular disease (for example, heart attacks and stroke), high blood pressure and diabetes. The group to be followed will consist of about 16,000 men recruited from about 40 VA Medical Centers across the country. Each man will be followed for at least five years depending on when he enters the study.

Detailed Description

The purpose of this study is to gather a mixed racial group of relatively healthy male Veterans (for example, White, African-American, and Hispanic), who are at least 50 years of age. These men will be followed to see what types of diseases they develop and to determine if racial differences in lifestyle, blood test results, or genes are related to the types of diseases that are found. Diseases of particular interest are prostate cancer, other cancers, cardiovascular disease (for example, heart attacks and stroke), high blood pressure and diabetes. The group to be followed will consist of about 16,000 men recruited from about 40 VA Medical Centers across the country. Each man will be followed for at least five years depending on when he enters the study.

Participants are asked to complete a set of forms to provide a brief medical history, demographics, information on lifestyle such as physical activities, smoking, and drinking, information on diet, and information on quality of life.

Subjects will be seen on a biannual basis with follow-up telephone interviews conducted during the intervening years. Follow-up telephone interviews will be conducted at the MAVERIC Call Center while follow-up clinic visits will take place at each SELECT site. In addition, VA clinical and administrative databases will be used to augment follow-up and confirm reported events.

During follow-up visits, participants will be asked whether they experienced any medical events since the last study visit, with information on specific diagnoses including prostate cancer, lung cancer, colon cancer, other cancers, stroke, myocardial infarction, hypertension, diabetes mellitus, kidney disease, chronic prostatitis, and benign prostatic hypertrophy. Confirmation of self-reported diagnosis will be made by an examination of discharge summaries, medical records, and available diagnostic and laboratory information by an end-points committee.

Recruitment for this observational cohort will proceed in parallel with recruitment for SELECT and can use SELECT staff and resources with very little additional burden in cost or staff time.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

50 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

Yes

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Prevalence of Chronic Conditions in African American and White Male Veterans
Time Frame: Every six months for at least five years
To determine whether differences in the prevalence of common chronic conditions affecting older Veterans among African-American and white male Veterans are explained by medical, lifestyle, dietary, or other risk factors.
Every six months for at least five years

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
