N2 - Low birth weight has been linked to insulin resistance and cardiovascular disease. We hypothesized that insulin sensitivity of both muscle and vascular tissues were impaired in young men with low birth weight. Blood flow was measured by venous occlusion plethysmography during dose-response studies of acetylcholine and sodium nitroprusside in the forearm of fourteen 21-yr-old men with low birth weight and 16 controls of normal birth weight. Glucose uptake was measured during intraarterial insulin infusion. Dose-response studies were repeated during insulin infusion. The maximal blood flow during acetylcholine infusion was 14.1 +/- 2.7 and 14.4 +/- 2.1 [ml x (100 ml forearm)(-1) x min(-1)] in low and normal birth weight subjects, respectively. Insulin coinfusion increased acetylcholine-stimulated flow in both groups: 18.0 +/- 3.1 vs. 17.9 +/- 3.1 [ml x (100 ml forearm)(-1) x min(-1)], NS. Insulin infusion increased glucose uptake significantly in the normal birth weight group, compared with the low birth weight group: 0.40 +/- 0.09 to 1.00 +/- 0.16 vs. 0.44 +/- 0.09 to 0.59 +/- 0.1 [ micro mol glucose x (100 ml forearm)(-1) x min(-1)], P = 0.04. Young men with low birth weight have normal insulin-stimulated endothelial function and impaired insulin-stimulated forearm glucose uptake. Thus, endothelial dysfunction does not necessarily coexist with metabolic alterations in subjects with low birth weight.
