카요 우에다 교수의 연구실은 대기오염 물질, 특히 미세먼지(PM2.5 및 초미세먼지)와 화학성분이 건강에 미치는 영향을 중심으로 한 환경보건 연구를 수행하고 있습니다. 기상 조건, 화산먼지(아시안 먼지) 및 온도 변동과 같은 환경 요인과 호흡기 및 순환기 질환, 특히 어린이 천식 입원률과 심혈관 사망률 간의 연관성을 분석하고 있습니다. 장기적 및 단기적 노출 효과를 다각도로 평가하기 위해 통계모델링 기법을 활용한 고도화된 환경-건강 연구를 지속하고 있습니다.

This study showed that temperature fluctuation, SPM, and NO(2) were associated with an increased risk of hospitalization of children for asthma.
Asian Dust (AD) particles transported from source areas contribute to sharp increases in coarse particles in Japan. We examined the association of exposure to AD events with emergency ambulance dispatches in Nagasaki city. We also examined whether AD transported at different altitude routes from source areas influenced dispatch rates. Using lidar (light detection and ranging), we determined moderate AD days (0.066/km <dust extinction coefficient ≤0.105/km) and heavy AD days (0.105/km <dust extin
These findings suggest that some specific PM components have a more hazardous effect than others and contribute to seasonal variation in the health effects of PM2.5.
Positive associations between PM (2.5) and heart disease mortality in Japan were observed. The effects of PM(2.5) may vary by disease and age.
Small particles can reach alveoli without being trapped in the upper respiratory tract and may have a greater impact on health than larger particles. Given the limited knowledge on health effects of fine particulate matter (PM2.5) in Japan, the short-term effects of PM2.5 on daily mortality using the generalized additive model (GAM), generalized linear model (GLIM), and time-stratified case-crossover analysis were estimated. Daily mortality data were obtained from the Ministry of Health, Labor,
Long-term exposure to PM was not associated with increased cardiovascular mortality risk in this population-based cohort in Japan.
Long-term exposure to air pollution, especially for PM<sub>10</sub> and SO<sub>2</sub> was associated with self-reported high blood pressure, high blood cholesterol, and diabetes in subjects of TCS. Our study supports that exposure to air pollution increases cardiovascular disease risk factors for younger population.
Short-term health effects of ambient PM<sub>2.5</sub> have been established with numerous studies, but evidence in Asian countries is limited. This study aimed to investigate the short-term effects of PM<sub>2.5</sub> on acute health outcomes, particularly all-cause, cardiovascular, respiratory, cerebrovascular and neuropsychological outcomes. We utilized daily emergency ambulance dispatches (EAD) data from eight Japanese cities (2007-2011). Statistical analyses included two stages: (1) City-lev
We did not find any definite difference in the effect of high temperature on ambulance dispatches for different age groups. However, more measures should be taken for younger and middle-aged people to avoid heat-related illnesses.
