Abstract

With the introduction of life-course epidemiology, researchers realized the importance of identifying risk factors in early life to prevent chronic diseases. This led to the establishment of the Ewha Birth and Growth Study in 2001; the study is a prospective birth cohort designed to provide evidence of early life risk factors for a child’s growth and health. Participants were recruited from those who visited Ewha Womans University Mokdong Hospital (a tertiary hospital in southwest Seoul, Korea) for prenatal care at 24-28 weeks of gestation. In total, 891 mothers enrolled in this study between 2001 and 2006 and their offspring (n=940) were followed-up. Regular check-up examinations of offspring were conducted at 3 years, 5 years, and 7 years of age and every year thereafter. To consider age-related health issues, extensive data were collected using questionnaires and measurements. In 2021, the study subjects will reach 19 years of age, and we are planning a check-up examination for early adulthood. About 20 years have passed since the cohort data were collected, and we have published results on childhood health outcomes associated with prenatal and birth characteristics, genetic and epigenetic characteristics related to childhood metabolism, the effects of exposure to endocrine disruptors, and dietary patterns in childhood. Recently, we started reporting on topics related to adolescent health. The findings will facilitate identification of early life risk factors for chronic diseases and the development of interventions for diseases later in life.

Key Message
To provide evidence of early life risk factors for the prevention of chronic diseases, the Ewha Birth and Growth Study was started in 2001. The Ewha Birth and Growth cohort is a leading long-term follow-up study in Korea, and we have published results on childhood health outcomes associated with prenatal and birth characteristics, genetic and epigenetic characteristics related to childhood metabolism, the effects of exposure to endocrine disruptors, and dietary patterns in childhood. We are planning to collect data for early adulthood, and our findings will contribute to the development of interventions to prevent chronic diseases.

Abstract

<sec><title>OBJECTIVES</title>The objective of this study was to estimate the prevalence of depression in medical students and to evaluate whether interpersonal social support, health-related behaviors, and socio-economic factors were associated with depression in medical students.</sec><sec><title>METHODS</title>The subjects in this study were 120 medical students in Seoul, Korea who were surveyed in September, 2008. The subjects were all women and over the age of 20. Their age, body mass index (BMI), quality of sleep, diet, household income, smoking, alcohol consumption, exercise levels, and self-reported health status were surveyed. The degree of perceived social support was measured using the interpersonal support evaluation list (ISEL). Depression was evaluated using the center for epidemiology studies depression scale (CES-D).</sec><sec><title>RESULTS</title>The mean CES-D score was 14.1±8.6 and 37.1% of the participants appeared to suffer from depression. Low levels of perceived interpersonal support increased the risk of depression by more than 10 times and having higher household income did not necessarily decrease the risk of depression.</sec><sec><title>CONCLUSION</title>Medical students have a relatively high level of depression. Efforts should be made to encourage social support in order to promote mental health in medical students.</sec>

Abstract

OBJECTIVES
Hebei Spirit oil spill accident has brought about the worst coastal oil contamination in Korean history. Following the accident, residents and volunteers, number exceeding a million from nationwide, were exposed to chemicals from the crude oil itself and dispersants, including volatility organic compounds (VOCs), polycyclic aromatic hydrocarbons (PAHs), and heavy metals through the clean-up works over months. This study was undertaken to investigate the effect of clean-up work on the peripheral nerve function and psychologic status of the residents after a prolonged exposure to clean-up work after the oil spill exposure.

METHODS

We performed a study on the residents of Jango-do Island, Chungnam, on 5 and 12 January 2008, six to eight weeks after the accident. A questionnaire on general characteristics, Korean Beck Depression Inventory (K-BDI), color vision test (Lanthony desaturated D-15 test), and vibration perception threshold test were done. Among 210 residents with 30 years or older, 63 (30%) finished questionnaires and completed at least one among K-BDI, color vision test, or vibration perception threshold test. Descriptive statistics was done on the residents.

RESULTS

The residents participated in clean-up work for average 20 days, max 30 days, during 6 weeks following the accident. Average work hours were 7.4 hours per day, max 10 hours. On K-BDI, 21 (33.3%) had a severe depressive state. Mean color confusion index was 1.29 in the right and 1.20 in the left. Mean vibration perception threshold was 3.69 VU (right) and 3.55 VU (left), respectively.

DISCUSSIONS

AND CONCLUSIONS: Compared to literature report, the residents had higher depression scale. Color vision threshold was not higher compared to general population near an industrial complex. Vibration perception threshold was significantly higher than the residents of similar age living near an abandoned mine in southern coastal area only in the age group of forties. These suggests there is some evidence of neuropsychiatric effect related to oil cleaning work and a mid- and long-term study of the oil exposure health effects with continuous monitoring should be done for the exposed residents in the affected area.

Abstract PDF: Abstract
OBJECTIVES
We aims to construct Infant Growth Cohort for evaluating whether oxidative stress in midterm pregnancy has an adverse effect on postnatal growth.
METHODS
AND MATERIALS: From September 2001 to April 2004, we constructed an Ewha Infant Growth Cohort connected with the Ewha Pregnant Women Cohort. We excluded mother-and-child pairs in which the mother had experienced hypertension or diabetes during pregnancy and had multiple births for this study, which gave us 233 mother-and-child pairs for analysis. We measured maternal serum homocysteine and urinary 8-hydroxyguanosine (8-OHdG) and malondialdehyde (MDA) at 24~28 weeks of pregnancy, and infant weights at birth and at 6 and 12 months postnatally. We applied repeated measures ANOVA with PROC MIXED to assess the significance of differences.
RESULTS
We followed 64 and 85 infants at 6 and 12 months respectively. The mean body weights were 3146.4 g at birth, 8229.7 g at 6 months, and 1006.47 g at 12 months. The mean birth weight of infants was lower in mothers with higher homocysteine levels (third and fourth quartiles), but body weights from the first- and fourth-quartile groups of maternal homocysteine levels were lower than the others even though it was not statistically significant. Body weights at birth and at 6 months in third- and fourth-quartile groups of 8-OHdG levels were lower than the others. The body weights in the fourth quartile MDA group were significantly lower than the others at all time points.
CONCLUSIONS
Maternal oxidative stress in midterm pregnancy may cause postnatal growth retardation. But, there were high rate of follow up loss and various measurement errors. Therefore, we need to have efforts for compete follow up and valid and reliable measurements.; Summary
