Adherence to breast and cervical cancer screening in Spanish women with diabetes: Associated factors and trend between 2006 and 2010

Abstract

This study aimed to assess the adherence to breast and cervical cancer screening of women with diabetes mellitus (DM), and the associated factors and trend of use over time of these preventative services between 2006 and 2010 in Spain. The study used data from a population of women aged greater or equal to 18 years (n=11,957) who participated in the European Health Interview Survey in Spain (EHISS, 2009). Diabetes status was self-reported and included those with type 2 DM. Adherence to screening for cancer prevention was assessed by asking women aged greater or equel to 40 years whether they had undergone mammography and a Papanicolaou (Pap) cervical smear (in those aged 18-69 years) within the previous 2 and 3 years, respectively. Independent variables included sociodemographic and health-related characteristics. Also, the age-standardized prevalences of mammography and Pap smear uptake were compared in women with diabetes between 2006 and 2010. Among the diabetic women, 37.9% underwent mammography and 49.1% had a Pap smear vs 53.8% and 64%, respectively, in women without diabetes, with corresponding adjusted odds ratios of 0.81 (95% CI: 0.68-0.97) and 0.74 (95% CI: 0.60-0.91). Among diabetic women, attending more "physician visits" was a positive predictor of having both screening tests. Also, a higher monthly income level was associated with mammography uptake, and a higher educational level with Pap smear uptake. There was also a significant decrease in mammography screening uptake between 2006 and 2010 compared with a stable rate of uptake of cervical cancer screening. Spanish women with diabetes consistently underuse breast and cervical cancer screening tests compared with non-diabetic women. The decline in mammography uptake rates needs to be carefully monitored and may even call for intervention.
