To analyze the compliance of urban populations at high risk of breast cancer in Nanchang City from 2021 to 2023 and explore potential influencing factors, in order to provide a scientific basis for improving screening participation rates and optimizing screening strategies.
Permanent registered residents aged 45-74 years in Nanchang City were selected for a breast cancer risk factor survey and risk assessment. Individuals assessed as high-risk for breast cancer were recommended to undergo combined breast ultrasound and X-ray examinations at designated hospitals. SPSS 25.0 was used to perform χ2 analysis to compare screening participation rates across groups with different characteristics. Multivariable logistic stepwise regression analysis was also conducted to identify factors associated with screening participation.
A total of 9 138 high-risk individuals for breast cancer were enrolled, of whom 4 228 participated in breast cancer screening, yielding an overall participation rate of 46.27%. Multivariable logistic stepwise regression analysis showed that higher education level (OR=1.235, 95% CI: 1.052-1.450), current smoking (OR=1.519, 95% CI: 1.296-1.779), exposure to secondhand smoke (OR=1.784, 95% CI: 1.621-1.964), history of childbirth (OR=2.631, 95% CI: 2.141-3.233), history of benign breast disease (OR=1.846, 95% CI: 1.683-2.025), and family history of breast cancer in blood relatives (OR=1.560, 95% CI: 1.406-1.731) were facilitating factors for screening participation (P<0.05). In contrast, age 65-74 years (OR=0.572, 95% CI: 0.508-0.645), screening in 2022 (OR=0.644, 95% CI: 0.573-0.724) and 2023 (OR=0.709, 95% CI: 0.637-0.789), engaging in physical exercise ≥3 times per week (OR=0.763, 95% CI: 0.691-0.844), and history of breastfeeding (OR=0.882, 95% CI: 0.803-0.970) were inhibiting factors for screening participation (P<0.05).
The screening rate among urban populations at high risk of breast cancer in Nanchang City was relatively low and influenced by multiple factors, including education level, smoking history, childbirth history, breastfeeding history, physical exercise, and family history of breast cancer. It is recommended to adopt targeted health education, strengthen social support networks, and focus on subgroups with low screening participation in future efforts to improve screening coverage and enhance prevention and control outcomes.
