Trial Outcomes & Findings for A School-Based Intervention to Reduce Lyme Disease (NCT NCT00594997)

NCT ID: NCT00594997

Last Updated: 2025-10-03

Results Overview

Parents of children were asked at baseline to report any new case of Lyme Disease within the past 12 months. This question was asked again a year later after receiving the educational intervention was given. We then will compare the number of reported Lyme Disease cases at baseline to the number of Lyme disease cases reported a year later. New cases of Lyme Disease had to be confirmed by medical record review.

PRIMARY outcome

Timeframe: baseline - 1 year

Population: Number of Lyme cases reported in the intervention and control groups

Parents of children were asked at baseline to report any new case of Lyme Disease within the past 12 months. This question was asked again a year later after receiving the educational intervention was given. We then will compare the number of reported Lyme Disease cases at baseline to the number of Lyme disease cases reported a year later. New cases of Lyme Disease had to be confirmed by medical record review.

Education
n=10 Participants

Control
n=4 Participants
The number of incident cases of Lyme reported by parents of students in the control group. These students did not receive the educational intervention.

1 Number of cases incident Lyme disease

SECONDARY outcome

Timeframe: baseline -1 year

Population: Composite knowledge score for intervention and control students post-intervention. Comparing the change in score between intervention and controls between pre and post evaluation.

Three outcome measures, knowledge of LD transmission, self reported tick bite precautionary behaviors and attitudes towards taking precautions were measured. A Lyme Disease knowledge score was created from totaling the number of correct answers on the 6 knowledge questions, ranging from 0-6. A score with a higher value indicated an increase in the desired behavior. These questions were asked before and after the intervention to compared the change from preintervention with postintervention between intervention and control students, adjusted for age, sex and pre-knowledge score. Precautionary behavior outcomes were graded on a linear scale quantifying the amount of practice.
