Uptake of breast screening and associated factors among Hong Kong women aged ≥50 years: a population-based survey.

ABSTRACT

OBJECTIVE: To examine the uptake of breast screening and its associated factors among Hong Kong Chinese women aged ≥50 years. STUDY DESIGN: Cross-sectional population-based survey. METHODS: A sample of Hong Kong Chinese women was recruited through telephone random-digit dialling. The survey consisted of six sections perceived health status, use of complementary medicine, uptake of breast screening, perceived susceptibility to cancer, family history of cancer and demographic data. The factors associated with uptake of breast screening were analysed using logistic regression analysis. RESULTS: In total, 1002 women completed the (anonymous) telephone survey. The mean age was 63.5 (standard deviation 10.6) years. The uptake rate of breast screening among Hong Kong Chinese women aged ≥50 years was 34%. The primary reasons for undertaking breast screening were as part of a regular medical check-up (74%), prompted by local signs and symptoms (11%) and a physician's recommendation (7%). Higher educational level, married or cohabiting, family history of cancer, frequent use of complementary therapies, regular visits to a doctor or Chinese herbalist, and the recommendation of a health professional were all independently and significantly associated with increased odds of having had a mammogram. CONCLUSIONS: This study provides community-based evidence of the need for public health policy to promote broader use of mammography services among this target population, with emphasis on the active involvement of health care professionals, through the development and implementation of appropriate evidence-based and resource-sensitive strategies.
