Background

A population‐based screening programme for abdominal aortic aneurysm (AAA) started in 2010 in Stockholm County, Sweden. This present study used individual data from Sweden's extensive healthcare registries to identify the reasons for non‐participation in the AAA screening programme.

Method

All 65‐year‐old men in Stockholm are invited to screening for AAA; this study included all men invited from July 2010 to July 2012. Participants and non‐participants were compared for socioeconomic factors, travel distance to the examination centre and healthcare use. The influence of these factors on participation was analysed using univariable and multivariable logistic regression models.

Results

The participation rate for AAA screening was 77·6 per cent (18 876 of 24 319 men invited). The prevalence of AAA (aortic diameter more than 2·9 cm) among participants was 1·4 per cent. The most important reasons for non‐participation in the multivariable regression analyses were: recent immigration (within 5 years) (odds ratio (OR) 3·25, 95 per cent confidence interval 1·94 to 5·47), low income (OR 2·76, 2·46 to 3·10), marital status single or divorced (OR 2·23, 2·08 to 2·39), low level of education (OR 1·28, 1·16 to 1·40) and long travel distance (OR 1·23, 1·10 to 1·37). Non‐participants had a higher incidence of stroke (4·5 versus 2·8 per cent; P < 0·001) and chronic pulmonary disease (2·9 versus 1·3 per cent; P < 0·001). Daily smoking was more common in residential areas where the participation rate for AAA screening was low.

Conclusion

Efforts to improve participation in AAA screening should target the groups with low income, a low level of education and immigrants. The higher morbidity in the non‐participant group, together with a higher rate of smoking, make it probable that this group also has a high risk of AAA.
