When abdominal ultrasound is performed it is general practice to examine not only the organs needed to answer the clinician's question but also the remaining abdominal and pelvic organs for which there is no clinical indication (= routine examinations). We investigated the effect of these routine examinations on the further management in 533 medical outpatients (222 women; 311 men; age 45 +/- 16 years). Of 7684 organs examined, 6194 (81%) were routine examinations, 469 of which revealed unexpected abnormalities. Only 19 of these were considered clinically relevant enough to warrant further work-up, and long-term follow-up was regarded as necessary in 6 patients only. However, an abnormal finding on routine examination had no eventual therapeutic implications in any patient. We conclude that in middle-aged medical outpatients it is sufficient to perform sonography on those abdominal and pelvic organs which need to be examined to answer the clinician's questions. Failure to routinely examine the remaining organs does not lead to a relevant loss of information, but may save time and money on fruitless work-up of unexpected findings.
The relation between the abdominal accumulation of body fat, total-body adiposity, and blood glucose level and the risk of non-insulin-dependent diabetes mellitus was evaluated prospectively among 1,972 male participants in the Department of Veterans Affairs Normative Aging Study cohort. The risk of non-insulin-dependent diabetes mellitus was assessed by means of the proportional hazards model; 226 cases of diabetes occurred among the 1,972 men (mean age at entry, 41.9 years; range, 22-80 years) over 35,496 person-years of observation. The relation of body mass index to diabetes risk was partly explained by body fat distribution; after adjusting for age, the ratio of abdominal circumference to hip breadth, and cigarette smoking, men in the top tertile for body mass index had a 1.3-fold greater risk of diabetes than did men in the lowest tertile (95% confidence interval 0.9-1.8). Moreover, after adjusting for age, body mass index, and cigarette smoking, men in the top tertile for the ratio of abdominal circumference to hip breadth had a 2.4-fold greater risk of diabetes than did men in the lowest tertile (95% confidence interval 1.7-3.7). When blood glucose was analyzed as a continuous outcome variable, the findings were consistent, i.e., a positive association with abdominal fat independent of total-body adiposity. These results confirm previous reports of a prospective relation between abdominal adiposity and the risk of diabetes and provide prospective evidence of a relation between blood glucose levels and both body fat distribution and obesity.
