Predictors of mammography uptake in Korean women aged 40 years and over.

AIM
This paper is a report of a study performed to identify the predictors of mammography uptake for Korean women according to the stage of change, as determined by the transtheoretical model.


BACKGROUND
Although breast cancer is the most common female cancer in South Korea, its early detection rate here is low when compared with other developed countries. The transtheoretical model can be used to facilitate health promotion based on individual health behaviour and to devise stage-tailored interventions.


METHOD
The participants were a convenience sample of 920 women aged > or =40 years between December 2005 and February 2006. A cross-sectional design was used in which participants completed a questionnaire that consisted of measures of the transtheoretical model. To provide a standard of measure, the variables were converted from raw scores to standard scores and then to T scores (mean = 50, sd = 10). Logistic regression analysis was then used to estimate predictors of the stage of maintenance of mammography uptake.


FINDINGS
The most frequent stage of mammography uptake was 'contemplation'. Predictors of mammography uptake included decisional balance, commitment to regular screening and avoiding contact with the healthcare system. Commitment to regular screening and breast self-examination were strongly related to mammography maintenance.


CONCLUSION
The results of this study can be used for the development of theory-based and empirically supported mammography uptake intervention strategies and programmes directed towards women aged > or =40 years.
