Can life-styles of subjects with impaired glucose tolerance be changed? A feasibility study.

Author information

Diabetes Research Laboratories, Radcliffe Infirmary, Oxford, UK.


Thirty-one subjects with impaired glucose tolerance were randomly allocated to a group receiving advice to improve their diet and physical activity levels over 6 months (n = 23) or to a control group (n = 8). At 6 months, 18 of the 23 subjects receiving 'healthy living' advice were re-examined (five subjects had withdrawn). Fourteen of the 18 subjects showed an alteration in diet or an increase in exercise. The 18 subjects re-evaluated showed a reduction in systolic blood pressure (118 +/- 15 vs 124 +/- 15 mmHg, p less than 0.05) and decrease in total plasma cholesterol (4.5 +/- 1 vs 5.2 +/- 1 mmol l-1, p less than 0.01) and LDL-cholesterol levels (2.8 +/- 0.9 vs 3.2 +/- 0.9 mmol l-1, p less than 0.05). Plasma glucose levels were unchanged. One subject withdrew from the control group. At 6 months, the seven control subjects examined showed no significant change in metabolic parameters, with little measurable change in diet or exercise. At 2 years, 17 of the 23 'healthy living' subjects were reassessed. Nine of the subjects had continued to exercise or maintained a decreased weight compared to baseline. Fasting plasma glucose levels had increased (6.0 +/- 1.2 vs 5.5 +/- 0.6 mmol l-1, p less than 0.05), with the only continued improvement being a reduced LDL level (2.8 +/- 0.7 vs 3.1 +/- 0.9 mmol l-1, p less than 0.05). At 2 years, a similar proportion of the control group were taking regular exercise compared with the 'healthy living' group.(ABSTRACT TRUNCATED AT 250 WORDS).
