Inexpensive, locally-produced ceramic cook stoves may produce less smoke than traditional indoor 3-stone fire pits, but they don't significantly reduce indoor air pollution or the risk of pneumonia in young children, according to results from a small, year-long observational study by researchers from the U.S. Centers for Disease Control and Prevention working in rural Kenya. "This research on cook stoves illustrates that the approach to improving children's health must employ strategies that take a holistic view of the child, one that includes the home," said Dr. David H. Walker, the new president of the American Society of Tropical Medicine and Hygiene and chairman of the department of pathology at UTMB. "Data from this and further studies will help aid programs make evidence-based decisions as they determine where to allocate their increasingly scarce funds."
