Lifestyle as regards physical exercise, smoking and drinking, of adult insulin-treated diabetic people compared with non-diabetic controls

Chronic complications in diabetes are sometimes associated with living habits. To investigate whether diabetic people's habits of smoking, drinking alcohol and taking physical exercise differed from those of the general population, a questionnaire was sent to 561 insulin-treated diabetic people and to 1,125 controls, matched for age, sex and domicile. Diabetic people were current smokers as often as controls (21% vs 23%; ns), but they drank less alcohol and more of them were non-drinkers (22% vs 13%; p < 0.001). Diabetic people more often took physical exercise than did controls (40% vs 28%; p < 0.001). Diabetic women were more seldom smokers (18% vs 26%; p < 0.05), more often non-drinkers (26% vs 14%; p < 0.001) and exercised regularly more (44% vs 28%; p < 0.001) than female controls. Diabetic men were more similar to male controls in their habits. Young diabetic people drank less alcohol and were more often non-drinkers (22% vs 9%; p < 0.001) compared with their controls. Comparison within the diabetic group showed that men drank alcohol more frequently and in greater amounts, and that more women were non-drinkers (26% vs 18%; p < 0.05). People with chronic complications drank less frequently and exercised less regularly (34% vs 44%; p < 0.05) than those without complications. These findings suggest that diabetic people's smoking, drinking and exercise habits are rather similar to general people's. However, diabetic women seem to take risk factors for developing complications into consideration more than men, which could reflect a true gender pattern and/or be an effect of worrying more about diabetes.
