Socioeconomic position and cardiovascular risk factors among people with screen-detected Type 2 DM: Six-year follow-up of the ADDITION-Denmark trial

Abstract Aims To examine whether socioeconomic position (SEP) was associated with change in cardiovascular risk factors and meeting treatment targets for cardiovascular risk factors among individuals with screen-detected Type 2 DM at six-year follow-up. Methods The study population was 1533 people with Type 2 DM identified from at stepwise diabetes screening programme in general practice during 2001–2006 in the ADDITION-Denmark study. The ADDITION-study was performed as a randomised trial but the two randomisation groups were analysed as one cohort in this study. Cardiovascular risk factors were measured at baseline and repeated at follow-up (mean: 5.9 [1.4] years). Information on SEP, redeemed antihypertensive and lipid-lowering treatment were obtained from Danish registers. Multivariate analyses were performed to estimate change in cardiovascular risk factors and difference in meeting treatment targets. Results The change in HbA1c , cholesterol, blood pressure and BMI were virtually the same across educational level, income level, occupational status or cohabiting status. Overall, the ability to meet treatment targets for HbA1c , cholesterol and blood pressure was not modified by SEP-group. A higher proportion of people with lower educational level or lower income level in the intensive care redeemed anti-hypertensive treatment compared to people with higher educational or income levels. Conclusion Screen-detection and early treatment onset did not introduce socioeconomic inequality in metabolic control in people with screen-detected Type 2 DM at six-year follow-up.
