Study Manager Jacque DeMatteis said that currently, 12 interviewers scour the county for volunteers to participate in the sample group. Based on demographic factors gathered in the preliminary meeting, potential volunteers may be asked a series of questions related to health history and personal habits, or excused for not conforming to the survey data needed from a particular demographic. The sample data compiled in Trigg County and other locations will be compiled to form a representative sample of the entire United States population. Of a core group of over 1,000 potential surveyed volunteers, she hopes to complete examinations and collect data on 400-450 residents.
DeMatteis said that if suitable for the study, the interview could last as little as 30 minutes for a child, to 45 minutes to an hour for adults. “One of the variables in the length of time it takes for a survey is we enter all the medicines and supplements a sampled person uses.”
“If for instance, all members of a family of four are selected, we could interview a teenage child on his or her own, interview one of he parents for a young child and interview the husband wife on their own. We try to make this as user friendly as possible. If people are busy, we will gladly come back at a more convenient time.”
