Objectives : The reproductive history of women has been suggested to have a possible influence on the risk of osteoporotic fractures. The purpose of this study was to assess the association between reproductive history and hip fractures in the elderly women. Methods : The study subjects were drawn from women members of the Korean Elderly Pharmacoepidemiologic Cohort (KEPEC), aged 65 years or over, whose reproductive histories were available, and who were beneficiaries of the Korea Medical Insurance Corporation (KMIC) in 1993 and lived in Busan city, Korea. The information on reproductive histories, and possible confounders, were collected from mailed questionnaires. Potential hip fracture cases were collected from the claims data obtained between 1993 and 1998, with a hospital survey conducted to confirm the final diagnoses. Rate ratios and their 95% confidence intervals, were calculated using a Cox's proportional hazard model. Results : Following up 5,215 women for 6 years, 51 cases were confirmed with hip fractures. When adjusted for age, weight and physical activity, the rate ratio of hip fractures in women who had given birth three or more times was 0.56 (95% CI: 0.25-1.25), compared with those who had given birth two or less times. When adjusted for age, number of births, weight and physical activity, the rate ratio in women who first gave birth when younger than 22 years was 0.60 (95% CI: 0.34-1.08) compared with those who had giving birth at 22 years or older. Conclusions : According to these findings, an early age when first giving birth might decrease the risk of hip fractures in elderly Korean women.

Recent epidemiologic studies show that gestational exposure to air pollution adversely affects pregnancy outcomes including low birth weight in preform birth. In this study, we evaluated the effect of air pollutants on LBW (low birth weight) on firstborn fetus throughout the gestational period using the birth cohort between 1999 and 2003 in Seoul. Using birth cohort data from the National Statistics Office of Korea we identified 288,346 firstborn births (excluded missing data on lack of information for birth weight and discordance between residential and certificated address from a total of 316,451) during 1999 to 2003 with complete covariate (gender, parity, date of birth, gestational age, parental age and educational level, maternal occupation etc.) and maternal residential history data. Our subjects were defined as more than 37 weeks and less than 44 weeks of completed gestation and we identified 5,457 persons (1.89%) by low birth weight (<2.5 kg) in this study. Using logistic regression, we estimated the risk of mean (entire pregnancy and trimester period) air pollution concentrations for CO, $O_3,\;PM_{10},\;NO_2\;and\;SO_2$. In terms of trimester-specific exposure, we found that some air pollutants exposure in each trimester would increase the risk for LBW. Results also showed that the effect size of air pollutants exposure during the first and third trimester is higher than during the second trimester. In all trimester, the estimated risk of LBW was 1.831 (95% CI=1.573-2.132) with unit increase for CO, 1.139 (95% CI=1.107-1.172) for 50, and 1.009 (95% CI=1.001-1.017) for $O_3$. Our results suggest that exposure during the gestation period to relatively low levels of some air pollutants may be associated with a reduction in birth weight on first-born fetus. These findings implicate the effective risk management strategies should be applied to minimize the public health impacts for pregnant women.

This study had two goals: 1) to explore generational differences in traditional family rituals and 2) to investigate the association between family values and family rituals. Using survey data from 500 married men and women in their 20s to 60s, we classified three generations: 1) 1941-1950 birth cohort (aged 59-68), 2) 1951-1970 birth cohort (aged 39-58), and 3) 1971 and later cohort (aged 38 or less). These generations represented post-colonialism, modernization, and the information era in Korea, respectively. The results demonstrated that birth-related traditional family rituals had been maintained across the generations. Ancestor worship was less likely to be observed by later generations. Further, the way in which family values was associated with family rituals differed across the generations, indicating that traditional family values had different influences on everyday family life culture across generations.

Objectives : This study was performed to examine the relationship between maternal exposure to environmental tobacco smoke (ETS) and pregnancy outcomes (low birth weight or preform baby) in a prospective cohort study. Methods : We made a pregnant women's cohort, and followed the pregnancy outcomes, between May 1st 2001 and August 31st 2002. We surveyed 2,250 women who visited our hospital during their 35th gestational week, with a self-administered questionnaire. The final total of mother-infant pairs analyzed in this study was 1,712. We used a multiple logistic regression analysis to analyze the effect of maternal ETS on the incidence of preform or low birth weight, and a linear regression analysis for the birth weight and gestational age. Results : Higher exposure to ETS (>=1 hours/day) during pregnancy was more negatively associated with the gestational age and birth weight, than no exposure to ETS (no or less than 1 hour). Maternal exposure to ETS was associated with preform baby(adjusted odds ratio (AOR) 1.7; 95% confidence interval (CI) 0.9, 3.3) and low birth weight (AOR 2.3; 95% CI 0.9, 5.5). In addition, we found that maternal ETS may reduce the birth weight by 70g after adjusting for potential confounding factors. Conclusions : This study suggests that maternal exposure to ETS during pregnancy may increase the frequency of low birth weights and preform births.

To assess the proportion of spectacles-wearing and an aspect of familial aggregation of myoptic spectacles-wearing and to observe the birth cohort for myoptic spectacles-wearing, a nationwide self-administered questionnaire survey was conducted from March 11 to September 19, 1985 A probability sample of 13,346 persons was taken from 180 enumerated districts designated by the fifth nationwide tuberculosis prevalence survey from Korean Institute of Tuberculosis. The major findings of this survey are as follows: 1) Total of 62.5% of the study population lived in urban area whereas 37.5% lived in Eup-Myun area. There was statistically significant difference in age and sex distribution between two residential area. 2) The percentage of spectacles-wearing was 8.3% and among these, myoptic and hyperoptic spectacles were 6.0%, 2.3%, respectively. A total of 8.5% of the male study population wore spectacles and this was slightly higher than the female (8.0%). 3) Among the occupational groups, students were the highest myoptic spectacles-wearing group whereas professionals were the highest hyperoptic spectacles-wearing group. 4) The proportion of myoptic spectacles-wearing was higher in female students than in male students respectively 11.6%, 8.7%. There was an increasing tendency of spectacles-wearing as age increased. 5) The age-sex adjusted prevalence rate of myoptic spectacles-wearing by residential areas was 2 times higher in urban area than Eup-Myun area 6) A wearing of the myoptic spectacles in early age was observed in recent birth cohort than remote birth cohort. 7) There was a tendency of familial aggregation for myoptic spectacles-wearing. The proportion of myoptic spectacles-wearing was 6 times higher for those who had parents wearing spectacles. 8) 60.9% of the total myoptic spectacles-wearing persons received the eye-specialist's order and 44. 9% for the hyperoptic spectacles wearing.

Objectives : To investigate the effect of parents' social class on infant and child mortality rates among the birth cohort, for the period of transition to and from the Koran economic crisis 1995-2004. Methods : All births reported to between 1995 and 2004 (n=5,711,337) were analyzed using a Cox regression model, to study the role of the social determinants of parents in infant and child mortality. The results were adjusted for the parents' age, education and occupation, together with mother's obstetrical history. Results. The crude death rate among those under 10 was 3.71 per 1000 births (21,217 deaths among 5,711,337 births) between 1995 and 2004. The birth cohorts from lower educated parents less than elementary school showed higher mortality rates compared with those from higher educated parents over university level (HR:3.0 (95%CI:2.8-3.7) for father and HR:3.4 (95%CI:3.3-4.5) for mother). The mother's education level showed a stronger relationship with mortality among the birth cohort than that of the fathers. The gaps in infant mortality rates by parents' social class, and educational level became wider from 1995 to 2004. In particular, the breadth of the existing gap between higher and lower parents' social class groups has dramatically widened since the economic crisis of 1998. Discussions : This study shows that social differences exist in infant and child mortality rates. Also, the gap for the infant mortality due to social class has become wider since the economic crisis of 1998.

Background: In this prospective cohort study, we investigated the association between fatty acid ethyl esters (FAEEs) in meconium as biomarkers of prenatal ethanol exposure and growth deficits, as birth outcomes, that constitute several of the key cardinal features of fetal alcohol syndrome. Methods: A total of 157 meconium samples were collected from enrolled infants within 24 hours of birth, and nine FAEEs were quantified using liquid chromatography/tandem mass spectrometry. The relationships between cumulative concentrations of nine species of FAEEs in meconium and birth parameters of growth (age-sex-specific centiles of head circumference [HC], weight, and length) and respective and combined birth outcomes of growth deficits (HC ${\leq}10th$ centile, weight ${\leq}10th$ centile, and length ${\leq}10th$ centile) were determined. Results: Multivariate logistic regression analysis demonstrated that higher cumulative concentrations of meconium FAEEs correlated with elevated risks for HC and length, both, 10th percentile or less (adjusted odds ratio [aOR], 2.94; 95% confidence interval [CI], 1.12-7.74; P = 0.029) and HC and weight and length, all of them, 10th percentile or less (aOR, 3.27; 95% CI, 1.12-9.59; P = 0.031). Conclusion: The elevated cumulative FAEEs in meconium were associated with combined growth deficits at birth, specifically HC and length, both, 10th percentile or less, which might be correlated with detrimental alcohol effects on fetal brain and bone development, suggesting a plausible alcohol-specific pattern of intrauterine growth restriction.

Purpose: The study was done to explore growth variation in head circumference (HC) in extremely premature infants (EPI) with brain injury. Methods: A retrospective cohort study was conducted with 79 cohort samples from the archives of the catch-up growth project. Mean age of the infants was 29.2 weeks of gestation and mean HC, 27.1 cm at birth. Their HC measurements were retrieved from the archives up to 6 month of corrected age (CA) and analyzed against history of brain injury during hospitalization. Results: Overall growth retardation in HC was observed in the cohort sample compared to longer gestation premature infants. EPI with brain injury showed decreased HC compared to infants without brain injury, and resulting growth variation across 6 month of CA. Highest retardation in HC growth was observed in male infants with brain injury. Conclusion: Extreme preterm birth itself may function as a major obstacle against HC growth toward term age in EPI. Sustainability of brain injury could be observed with higher HC growth retardation after term. Evolutionary favor to female infants may exist in HC growth of EPI. Intensive education on HC monitoring is highly suggested for parents of EPI, particularly with children with brain injury.
