Objective: Mammography is essential for reducing breast cancer mortality; however, its performance varies globally. This study aimed to evaluate mammography screening outcomes in Korea over 12 years and investigate regional variations. Materials and Methods: We analyzed mammography data from 42 million Korean women, aged 40 years and older, who participated in the Korean National Cancer Screening Program (KNCSP) from 2009 to 2020. Performance metrics—including recall rate (RR), positive predictive value (PPV), sensitivity, specificity, false positive rate (FPR), cancer detection rate (CDR), interval cancer rate (ICR), and dense breast rate (DBR), were computed. Twelve-year trends in these metrics were analyzed using Joinpoint regression. Regional variations were also examined across Korea’s 237 districts, stratified by age groups. Results: From 2009 to 2020, 42165405 mammography screenings were conducted through the KNCSP, increasing from 2821132 screenings in 2009 to 3596204 in 2020. The RR decreased from 17.2% in 2009 to 11.2% in 2020 (average annual percent change [AAPC] = -3.7%), while the PPV increased from 0.8% to 2.8%; AAPC = 10.7%), the CDR increased from 1.5 to 3.1 per 1000; AAPC = 7.3%), and the ICR rose from 0.9 to 1.6 per 1000; (AAPC = 5.2%). Regional variations were noted; however, differences in the RR, sensitivity, specificity, and FPR decreased over time. Conclusion While mammography performance improved from 2009 to 2020, the PPV and sensitivity remain suboptimal, underscoring the need for continuous monitoring. Regional disparities in performance, although reduced, persist. These findings provide essential baseline data for improving mammography quality and addressing inequities in breast cancer screening.

Purpose: This study aims to analyze the essence of infant parenting experiences of Vietnamese immigrant mothers married to Koreans’. Methods: The study participants are mothers who came to Korea from Vietnam as marriage immigrants, and have an experience of parenting infants in less than one year or are currently parenting infants. Data collection was carried out by interviews, and Colaizzi’s phenomenological method was used for analysis. Results: Total 17 meaning units, 8 themes and 3 theme clusters were identified. The three theme clusters are as follows: 1) A strange land, journey to ‘mother’, 2) A moment of carelessness, an unexpected accident, 3) The first step to safe parenting. Conclusion Vietnamese immigrant mothers have experienced of a sudden transition to motherhood in Korea, and have raised their infants in a bicultural environment. While raising their infants, they have encountered unexpected accidents due to differences in parenting culture and lifestyle. Nevertheless, Vietnamese immigrant mothers have made efforts to care for their infants safely and have shared parenting responsibility with their husbands. They also recognized the need for infant safety education based on community support. Therefore, in the future, infant safety education programs that consider cultural differences will be necessary.
