The purpose of this study was to examine the risk factors of diabetes in non-diabetic adults and to determine the extent to which these adults are aware of those risk factors. This descriptive study was carried out in a Primary Health Center and 140 people, aged 30 years and older, non-diabetic, not having had acute infectious disease and not pregnant were recruited using a convenience sampling method. An Interview Form, Diabetes Risk Test and Diabetes Risk Awareness Questionnaire were used for collecting data. Diabetes risk factors such as age, body mass index (BMI), waist-hip scale, family history of diabetes, physical inactivity, cigarette use, hypertension and to bear large baby (:?'. 4000 gr) among women were assessed with blood glucose level. Scores of 10 or higher from Diabetes Risk test was accepted as evidence of diabetes risk in this study with a majority of the sample (75.7%) were in a high-risk group and an overall average score of 11.26±3.84. The mean age was 52.2±14.3 and most of the sample was women (67.9%). The major risk factors were physical inactivity (96.4 % in work activity, 89.2 % at leisure activity), Hypertension (41.4 %), Obesity (35.7 %), Age (27.9 % above 65), family history of diabetes (27. I %) and to bear large baby (25.2%) respectively. The average score for awareness of diabetes risk in this study was 10.7±2.7 (min:O- max: 15). Those individuals with hypertension, a family history of diabetes and who had had themselves tested for diabetes had significantly higher scores on the awareness test. The findings highlight the importance of prevention and early detection of diabetes for nursing implications.
