Non-attendance in mammography screening and women's social network: a cohort study on the influence of family composition, social support, attitudes and cancer in close relations.

BACKGROUND

Mammography screening can reduce breast cancer mortality. The aim of the present study was to investigate non-attendance in mammography screening in relation to different aspects of a women's social network, attitudes and cancer in close relations.

METHODS

Data from the Malmö Diet and Cancer Study baseline examination in 1991-1996 was used. A re-examination began in 2007, and 1452 women participated. Family composition, social support, sense of belonging, attitudes on screening and breast cancer risk and on previous cancer in close relations were investigated in relation to self-reported participation in mammography screening using logistic regression analysis, yielding odds ratios with 95 % confidence intervals.

RESULTS

Both attendees (98.0 %) and non-attendees (95.2 %) considered mammography screening important. Non-attendance in mammography screening was associated with being unmarried vs. married (2.40:1.30-4.45) and with not having vs. having children (1.77:1.08-2.92). Non-attendees planned to abstain from mammography screening in the future more often than attendees (4.78:2.56-8.90), and they had often abstained from cervical cancer screening (1.69:1.04-2.75). No other statistically significant association was found.

CONCLUSIONS

This study indicates that family composition, but not necessarily the presence or absence of social support, perceived cancer risk or cancer in close relations, may affect non-attendance in mammography screening. A positive attitude towards mammography screening was found among both attendees and non-attendees, although the latter group planned to a lesser degree to attend mammography screening in the future.
