Indoor pollutants are partly causes of chronic respiratory diseases in Vietnam's Ho Chi Minh City, a study has found.
The study, part of a five-year project starting in 2012, involved 506 houses with 1,561 occupants from five types: rented, rural, tube, slum and apartments, Vietnam News Agency reported Monday.
The five-year project involving Belgium and Vietnamese doctors sought to evaluate the prevalence of chronic respiratory diseases (CRD), identify the risks factors, and prevent the disease in Vietnam.
There was a 41.9 percent prevalence of all types of CRD, with only 15.3 percent of patients getting them medically diagnosed.
The prevalence of CRD and obstructive syndrome was higher in rural and rental houses than in apartments and tube houses.
