Contrasting income-based inequalities in incidence and mortality of breast cancer in Korea, 2006-2015.

Objectives: Breast cancer incidence and mortality rates in Korea are increasing. This study analyzed income-based inequalities in the incidence and mortality of women breast cancer from 2006 to 2015, using national data that covered all Korean women.

Methods: We used the National Health Information Database from 2006 to 2015.

Impact of the Korea Early Childhood Home-visiting Intervention (KECHI) on child health and development and maternal health: a randomised controlled trial protocol.

Introduction: Randomised controlled trials (RCTs) of early childhood home-visiting interventions led by nurses have been conducted mainly in Western countries, whereas such trials have been limited in non-Western cultures, including Asia. In South Korea, a national nurse home visit programme (Korea Early Childhood Home-visiting Intervention (KECHI)) was developed in 2020 and launched throughout the country. We designed a pragmatic RCT to evaluate the effectiveness of KECHI on child health and development and maternal health.

The association of women's experience of abuse in childhood with depression during pregnancy and the role of emotional support as a moderator.

Background: This study aimed to examine the prevalence of antenatal depression and experience of abuse during childhood, to analyze the association between having experienced childhood abuse and depression during pregnancy, and to explore the role of emotional support as a moderator of that association.

Methods: In total, 44,770 pregnant women were analyzed from the self-administered registry for risk assessment at community public health centers in Seoul, Republic of Korea, for home visiting service provision between 2015 and 2019. The Edinburgh Postnatal Depression Scale (EPDS) was applied for the assessment of depression.

Comparison of Bayesian Spatiotemporal Models for Small-Area Life Expectancy: A Simulation Study.

The purpose of this study was to assess the precision, uncertainty, and normality of small-area life expectancy estimates calculated using Bayesian spatiotemporal models. We hypothesized 6 scenarios in which all 247 districts of South Korea had the same year-specific female population of 500, 1,000, 2,000, 5,000, 10,000, and 25,000 individuals during the study period (2013-2017). We generated 1,000 hypothetical data sets for each scenario and calculated district-year life expectancies.

Prevalence of intimate partner violence victimization among Korean perinatal women and associated factors.

Objective: To determine the prevalence of intimate partner violence (IPV) victimization and the factors associated with IPV during pregnancy and the early postnatal period in Korean community samples.

Methods: We enrolled 5953 pregnant mothers and mothers with young children registered in the Early Life Health Management Program provided by 30 public health centers in Korea between 2020 and 2021. We used the Korean Hurt, Insult, Threaten, and Scream (K-HITS) questionnaire to measure IPV.
