, Jongmin Oh, Eunji Mun, Jung Eun Choi, Kyung Hee Kim, Ji Hyen Lee, Hae Soon Kim, Eunhee Ha The worldwide incidence of precocious puberty, which is associated with negative health outcomes, is increasing. Several studies have suggested that environmental factors contribute to the development of precocious puberty alongside genetic factors. Some epidemiological studies have provided limited evidence suggesting an association between exposure to air pollution and changes in pubertal development. This systematic review aimed to summarize existing evidence on the association between air pollution exposure and precocious puberty. Following the Preferred Reporting Items for Systematic reviews and Meta-Analyses guidelines, we searched two databases (PubMed and Web of Science) until August 2023. The included studies assessed the association between air pollutant exposure and the risk of precocious puberty, early menarche, or pubertal development. Two authors independently performed study selection and data extraction. A meta-analysis and analysis of the risk of bias were infeasible due to the limited number of studies and the heterogeneity among them. The literature search resulted in 184 studies, from which we included six studies with sample sizes ranging from 437 to 4,074 participants. The studies reported heterogeneous outcomes. Four studies found that increased exposure to air pollution was related to earlier pubertal onset. One study was inconclusive, and another suggested that air pollutant exposure may delay the onset of thelarche. Most studies suggest that exposure to air pollutants accelerates pubertal development; however, the results from the available studies are inconsistent. More extensive and well-designed longitudinal studies are required for a comprehensive understanding of the association between air pollution and precocious puberty.

The COVID-19 testing station, Ewha Safe Station, is the core element of ESC. Symptomatic students and faculty members perform a combo swab self-PCR test or receive a nasopharyngeal swab PCR test from experts to prevent the spread of COVID-19 through early detection and management. ESC is significant in that it detects infection risks and proactively implements preemptive measures in a university. The COVID-19 health response system model at the university level was applied for the first time in South Korea, reaching a milestone in the history of university health in South Korea. In particular, it is highly valuable that the test was free of charge, as it enabled all of the examinees to have easy access to the test through joint cooperation with the Seegene Medical Foundation. This is a successful example of cooperation between schools and private institutions for public health improvement. In the future, the direct and indirect effects of the establishment and implementation of ESC need to be evaluated and confirmed, and areas requiring improvements need to be identified in preparation for another infectious disease outbreak in the future.

We used annual mortality rate, prevalence, and environmental indicators data from the World Bank and World Health Organizations (WHO). Trend analysis of the two Koreas was conducted to evaluate changes in health status over time. Spearman’s correlation analysis was used to find out the correlation between environmental indicators and children’s health status.
We found a distinct gap in children’s health status between the two Koreas. While North Korea reported a higher death rate of children than South Korea, both showed a decreasing trend with the gap narrowing from 2000 to 2017. The prevalence of overweight and obesity increased and that of thinness decreased in both Koreas. Except PM2.5 exposure, South Korea reported higher figures in most indicators of air pollutant emissions (South Korea, mean (SD)=28.3 (2.0); North Korea, mean (SD)=36.5 (2.8), P-value=0.002).
This study empirically discovered the gaps and patterns of children’s health between South Korea and North Korea. North Korean children experienced more severe health outcomes than children in South Korea. These findings imply that epigenetic modification caused by environmental stressors affect children’s health in the two Koreas despite similar genetic characteristics. Considering the gaps in children’s health between the two Koreas, more attention and resources need to be directed towards North Korea because the necessary commodities and services to improve children’s health are lacking in North Korea.
, Kyoung Sook Jeong, EunMee Kim, Eunhee Ha The majority of South Korean females use sanitary pads, which contain various organic solvents which could be excreted before and during their menstruation. However, they are not provided with findings from studies about the health effects of sanitary pads. Therefore, this study aims to establish a list of potential health hazards of sanitary pads and address the need for further extensive research by pointing out the limitations of the previous literature. A systematic review was adopted to conduct quantitative and qualitative reviews based on the PRISMA (preferred reporting items for systematic reviews and meta-analyses). Studies from electronic databases such as PubMed, RISS, and Google Scholar were retrieved for the final analyses. In accordance with our findings, we proposed a set of limitations of the previous studies. A systematic review revealed that there were effects of sanitary pads on vaginal or vulvar skin, endometriosis, and vaginal microflora. The review also revealed that organic solvents, which sanitary pads are composed of, bring potential harmful effects on pregnancy, autoimmune disease, cardiovascular disease, and neurological development. Social environments such as hygiene use or puberty education also turned out to affect female health. It was inferred that a lack of non-occupational and domestic studies reflecting the distinguishing features of sanitary pads with a reliable sample size remains as an important limitation. This study suggests that organic solvents in sanitary pads may increase some health risks bringing reproductive, autoimmune, cardiovascular, and neurological effects. Due to a lack of studies, a more extensive study can contribute to the public health of South Korean females.

, Jin Young Kim, Jae Sun Ryu, EunHee Ha, Hyesook Park Although common cold is a major cause of morbidity among university students, studies on the risk factors in relation to physical, social, emotional life styles among university students are limited. We sought to evaluate the effects of life style, depressive symptoms, and social support in common cold among medical school students.
120 medical students were surveyed through a self-reported questionnaire. They were asked to rate the severity of eight respiratory symptoms of the Jackson Criterion during the previous month. The ratings were summed to calculate the total symptom score. Social support was assessed by using Interpersonal Support Evaluation List(ISEL). Depressive symptoms were assessed by using The Center for Epidemiologic studies Depression Scale(CES-D). A score of 16 or higher was used as the cut-off point for high depressive symptoms. Life style factors were also evaluated. that Wilcoxon rank sum test, Kruskal-Wallis test, Chi-square test, and logistic regression test were used.
The symptom score ranged from 0 to 18 and the median was 10 among those who had experienced symptoms. 33(34.4%) had experienced cold during the last month. The social support score ranged from 91 to 156 and the median was 113. The prevalence of high depressive symptoms was 36.7%. Students with lower social support and higher depressive symptoms had higher cold symptom scores, although it was not statistically significant. Students who had evaluated their sleep quality and health status as bad had higher cold symptoms scores. In multiple logistics regression analysis, depression, sleep quality, and self-perceived health status were either significant or border-line significant risk factors of cold.
Our study suggests that life style factors such as sleep quality and self-perceived health status is associated with an increased susceptibility to common cold.
