A comparison of perinatal mortality in Korea on holidays and working days
Insights
Infants born on holidays in Korea had a 24% higher perinatal mortality rate. This increased risk of infant death during holidays is linked to variations in perinatal care quality.
Area of Science:
- Public Health
- Epidemiology
- Perinatal Medicine
Background:
- Holiday births in Korea show a higher perinatal mortality rate compared to workday births.
- Understanding the reasons behind this disparity is crucial for improving infant outcomes.
Purpose of the Study:
- To investigate the difference in perinatal mortality between infants born on holidays and workdays.
- To identify the underlying causes of increased holiday perinatal mortality.
Main Methods:
- A cross-sectional study utilizing 1999 Korean vital statistics and National Infant Mortality Survey data.
- Analysis of 628,485 births, classifying mortality by day of the week.
- Logistic regression used to estimate odds ratios for holiday mortality, adjusting for confounding factors like birthweight.
Main Results:
- Perinatal deaths were 24% higher on holidays (PMR 16.4 vs. 12.8).
- The adjusted odds ratio for perinatal death among holiday births was 1.2 (95% CI, 1.1-1.3).
- Births on holidays were 33% lower than expected.
Conclusions:
- Higher perinatal mortality during Korean holidays is associated with variations in perinatal care quality.
- The findings suggest a need to address potential disparities in healthcare delivery during public holidays.
Objective:
To examine whether the perinatal mortality of infants born during holidays differs from that of infants born on workdays, and to elucidate its cause.
Design:
Cross-sectional study. Setting Vital statistics linked to the National Infant Mortality Survey data for 1999 births in Korea.
Population:
In all, 628 485 births in 1999 in Korea.
Methods:
Number of births and perinatal mortality were classified according to the day of the week using the occurrence index. After adjusting for confounding factors, the odds ratios (ORs) for increased holiday mortality were estimated using logistic regression.
Main Outcome Measure:
Birthweight-adjusted perinatal mortality.
Results:
Births on holidays were 33% fewer and perinatal deaths 24% higher than expected (PMR, Perinatal Mortality Rate, 16.4 versus 12.8; OR, 1.3; 95% CI, 1.2-1.4). After the adjustment of birthweight, gender, plurality and congenital anomalies, the odds ratio for death of infants born during holidays was 1.2 (95% CI, 1.1-1.3).
Conclusions:
The higher perinatal mortality during holidays in Korea appears to be due to different qualities of perinatal care, rather than difference in case-mix.
