Malnutrition is a serious problem for Guinea. A 2012 study reported high chronic malnutrition rates, with levels ranging from 34% to 40% by region, as well as acute malnutrition rates above 10% in Upper Guinea's mining zones. The survey showed that 139,200 children suffer from acute malnutrition, 609,696 from chronic malnutrition and further 1,592,892 suffer from anemia. Degradation of care practices, limited access to medical services, inadequate hygiene practices and a lack of food diversity explain these levels.
