objective
the aim of this study was to investigate the impact of the exposure to oil leak on pulmonary function and prevalence of asthma in
the elementary school students in taean, where were located in the western coast of republic of Korea and exposed to offshore oil
leak on December 7th , 2007
Subjects and methods
Of 662 eligible students, 477 (72.1%) subjects who agreed to and completed the health assessment were enrolled on June 2009.
A Questionnaire developed by the international study of Asthma and Allergic diseases in Children (issAC) was modified and used.
methacholine bronchial provocation tests (mBPt) were performed in 109 (22.9%) subjects who reported asthmatic symptoms in
the questionnaire. Participants were stratified into two exposure groups (high vs. low). general characteristics and asthma-related
symptoms, and prevalence of asthma were compared.
results
there were no statistically significant differences in sex, age, Bmi, and family history of asthma between the two groups. the
number of children who was previously diagnosed asthma, began wheezing after oil leak or had current asthma symptoms was
significantly higher in the high-exposure group than that in the low-exposure group (previously diagnosed asthma; 20.6% vs
11.6%, P=0.008, wheezing after the oil leak; 6.7% vs 1.0%, P=0.01, current asthma symptoms; 30.6% vs 18.6%, P=0.00). FEV1 was significantly lower in the high-exposure group than that in the low-exposure group (82.6±10.8% vs 85.2±10.3%, P=0.01).
those who showed positive (PC20°Â16mg/ml) response in the bronchial provocation test was significantly higher in the highexposure
group than that in the low-exposure group (18.2% vs 7.6%, P=0.00). logistic regression on asthma indicated increased
odds for male (Or: 1.88, 95%Ci: 1.04-3.41), children with family history of asthma (Or: 4.02, 95%Ci: 1.38-11.71), and highexposure
group (Or: 3.26, 95%Ci: 1.79-5.92) adjusting for age, sex, and Bmi.
Conclusion
the study suggest that exposure to oil leak can be a risk factor in the development of asthma in elementary school students
although the causality is not certain. Follow-up studies and further analyses with biologic exposure index will elucidate the
relationship between oil leak and asthma.

Background: the prevalence of COPD is increasing in india. Only few studies have been conducted in rural areas of india to find
out the prevalence of COPD and its relationship with tobacco smoking, environmental tobacco smoke (Ets) exposure and type of
cooking fuel used. Hence the present study was undertaken with the following objectives:i)
to find out the prevalence of COPD in adult subjects of 35 years and above.
ii) to determine the tobacco smoking, Ets exposure and type of cooking fuel used as an associated risk factor with COPD.
material and methods: Field survey was conducted for COPD epidemiology in the rural field practice area of Kempegowda institute
of medical sciences, Bangalore, india which covers a population of 44,387 residing in 71 villages using cluster sampling technique
with the help of previously validated and standardized translated kannada (local language) version questionnaire for diagnosis of
COPD among subjects of age 35 years and above. spirometry was performed to all those who gave positive response to COPD and
