Background: Despite the clinical importance of prediabetes, little is known about the level of prediabetes awareness amongst the first-degree relatives of diabetes in India. Methods: This was a prospective open label questionnaire study conducted among 553 first-degree relatives of diabetes patients recruited from selected colleges of Nilgiris district of TamilNadu.First degree-relatives awareness on prediabetes was assessed using a prediabetes awareness questionnaire. An education session using a prediabetes information pamphlet were provided. After a washout period of 10 days the questionnaire were readministered to study the impact of education provided. The chi square analysis was used to measure the level of association between the dependent & the independent variables. A paired samples T test was carried out to determine if the mean of pre & post education scores was statistically significant. Results: A paired samples t-test showed that the participant’s level of prediabetes knowledge increased from prediabetes awareness program, pre-program (M = 3.6, SD = 1.18) to post-program (M = 6.7, SD = 1.544; t = -47.01, p < 0.05, df = 552). Conclusion: Planning and implementing programs to motivate students to be responsible for their own health are of paramount importance.
