The aim was to investigate the association between socioeconomic position (SEP) and physical activity, alcohol consumption and smoking, motivation to change lifestyle and health advices from general practitioners (GPs) in individuals with diabetes. Data were provided by the Danish National Health Survey 2013 and 7504 adults (⩾ 40 years) with diabetes were included. Educational level was used as SEP indicator and categorized into low, middle and high SEP. Dependent variables included physical activity, alcohol consumption, smoking, motivation to change lifestyle and GP lifestyle advices. Multiple logistic regression analyses adjusted for age, body mass index and ethnic background were performed. Higher SEP were associated with reduced odds of being physically inactive (middle SEP odds ratio (OR) men 0.58 (95% confidence intervals 0.47-0.72) and women 0.59 (0.47-0.75)) and non-smoking (middle SEP OR men 0.74 (0.59-0.93) and high SEP OR women 0.54 (0.38-0.77)) compared to participants with a low SEP. Alcohol consumption above the recommended maximum was associated with high SEP in men, OR 1.83 (1.30-2.61). Elevated SEP was associated with a motivation to increase physical activity levels (middle SEP OR men 1.45 (1.19-1.76) and women 1.35 (1.09-1.67)), high SEP was associated with none advice from GPs regarding smoking cessation among women, OR 0.47 (0.25-0.89).
