Abstract

The Early ACTID Study is a randomised controlled trial of diet plus exercise vs. diet alone and usual care in adults with type 2 diabetes, who were recruited five to eight months after diagnosis. The purpose of this study was 1) develop intervention materials to facilitate change in physical activity levels, 2) describe objectively measured habitual physical activity, 3) examine change in physical activity over six months, 4) explore the use of pedometers and diaries to monitor daily physical activity over a six-month period, 5) describe CRF levels, and 6) explore the independent and interactive cross-sectional associations of physical activity and CRF and HbA1c and the clustering of cardiovascular risk factors (i.e., metabolic syndrome) among adults with recently diagnosed T2D recruited to the Early ACTID Study. 340 Participants (207 men, and 133 women), aged 59.3�10.38 years, were recruited to the study. Conclusions: Levels of physical activity and CRF were low in participants recruited to the Early ACTID Study. Although physical activity and CRF were not associated with glycaemic control, higher levels were associated with a lower prevalence of the metabolic syndrome. The protective effect of physical activity and CRF was stronger in women than men. The use of pedometers and diaries appears to be acceptable to adults with T2D who are attempting to increase their physical activity.
