RESUMEN
Objective@#To evaluate the association between atopic dermatitis (AD) and suicidal behaviors in adolescent defectors among residents who escaped from North Korean (adolescent defectors, n=423) and adolescents with South Korean parents (Korean adolescents, n=540,265). @*Methods@#The study used data from the Korea Youth Risk Behavior Survey conducted from 2011 to 2019. Differences in general characteristics, health behaviors, suicidal ideation, suicide plans, suicide attempts, and AD between adolescent defectors and Korean adolescents were examined. Multiple logistic regression analysis was used to determine the association between AD and suicidal behaviors. @*Results@#The adolescent defectors group had lower AD (16.3% vs. 24.2%), poorer subjective health (10% vs. 6%), smoked more (47% vs. 18%), drank more (60% vs. 43%), lived with family less frequently (56% vs. 96%), and were more than twice as likely to have depression (42% vs. 27%), suicidal ideation (30% vs. 14%), a suicide plan (23% vs. 5%), or have made a prior suicide attempt (19% vs. 3%) compared with the Korean adolescent group (p<0.001). The adjusted odds ratio for the adolescent defectors group compared to the Korean adolescent group was 1.66 for suicidal ideation, 3.59 for suicide plans, and 4.34 for suicide attempts (p<0.001). AD was found to be associated with suicide plans and attempts in adolescent defectors and associated with suicidal ideation in Korean adolescents. @*Conclusion@#AD was significantly associated with suicide plans and suicidal attempts among adolescent defectors and suicidal ideation in Korean adolescents, based on a random sample of middle- and high-school students.
RESUMEN
The aim of this study was to assess the prevalence of Marfan syndrome (MFS) in Korean adults. Data were collected from the National Health Insurance Service in Korea from 2006 through 2013. The data consisted of primary diagnoses related to MFS (Q87.4) diagnosed according to the 10th revision of the International Statistical Classification of Diseases and Related Health Problems. The age-standardized prevalence of MFS in adults was calculated using the estimated Korean population in 2010 as a reference. Overall, the prevalence of MFS was 0.90 per 100,000 persons in 2006 and 2.27 in 2013. For males in 2013, the prevalence per 100,000 persons was 2.61 in overall and 4.32 in 15–19 years-old. For females in 2013, the prevalence per 100,000 persons was 1.92 in overall and 3.02 in 10–14 years-old. In conclusion, currently, the age-standardized overall prevalence of MFS was 2.27 persons per 100,000 persons. And the overall age-standardized prevalence of MFS increased between 2006 and 2013 especially in 15–19 years-old males and 10–14 years-old females.
RESUMEN
OBJECTIVES: To date, studies have not comprehensively demonstrated the relationship between stroke incidence and socioeconomic status. This study investigated stroke incidence by household income level in conjunction with age, sex, and stroke subtype in Korea. METHODS: Contributions by the head of household were used as the basis for income levels. Household income levels for 21 766 036 people were classified into 6 groups. The stroke incidences were calculated by household income level, both overall within income categories and further by age group, sex, and stroke subtype. To present the inequalities among the six ranked groups in a single value, the slope index of inequality and relative index of inequality were calculated. RESULTS: In 2005, 57 690 people were first-time stroke patients. The incidences of total stroke for males and females increased as the income level decreased. The incidences of stroke increased as the income level decreased in those 74 years old and under, whereas there was no difference by income levels in those 75 and over. Intracerebral hemorrhage for the males represented the highest inequality among stroke subtypes. Incidences of subarachnoid hemorrhage did not differ by income levels. CONCLUSIONS: The incidence of stroke increases as the income level decreases, but it differs according to sex, age, and stroke subtype. The difference in the relative incidence is large for male intracerebral hemorrhage, whereas the difference in the absolute incidence is large for male ischemic stroke.
