Short\u2010term exposure to Asian dust has been associated with cardiovascular disease through mechanisms such as systemic inflammation. Because inflammation is a potential trigger of placental abruption, exposure may also lead to abruption. We examined whether exposure to Asian dust was associated with abruption.<\/jats:p><\/jats:sec><jats:sec><jats:title>Design<\/jats:title><jats:p>A bi\u2010directional, time\u2010stratified case\u2010crossover design.<\/jats:p><\/jats:sec><jats:sec><jats:title>Setting and population<\/jats:title><jats:p>From the Japan Perinatal Registry Network database, we identified 3014 patients who delivered singleton births in hospitals in nine Japanese prefectures from 2009 to 2014 with a diagnosis of placental abruption.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Asian dust levels were measured at Light Detection and Ranging monitoring stations, and these measurements were used to define the Asian dust days.
