This study was intended to determine frequency of obesity in a group of potential diabetics and find its relationship with age, sex, blood pressure and plasma 2hour post challenge glucose. Six hundred and eight subjects with impaired fasting glucose (IFG)/borderline fasting blood sugar (Borderline-FBS) levels (> 5.0 and< 7.0 mmol/L) on at least two occasions were successively recruited into the study as they present at our endocrine and special investigation clinic for the purpose of an oral glucose tolerance test (OGTT). There were 208males (34.21%) and 400females (65.79%). One hundred and seventy-six of the patients (28.95%) were found to be obese; one hundred and ninety-two (31.58%) were overweight while the remaining two hundred and forty (39.50%) had a normal body mass index. We conclude that a greater percentage of individuals with impaired fasting glucose are either overweight or obese and suggest that either being overweight or obese contribute to the onset of impaired glucose metabolism in them
