UNICEF's GOBI-FFF programs aim to reduce child mortality rates through relatively simple and inexpensive methods. The GOBI methods are: Growth monitoring to prevent malnutrition; Oral rehydration to treat diarrheal dehydration; Breastfeeding to provide optimal nutrition and immunity for infants; and Immunization to protect against diseases that kill or disable millions of children annually. The additional FFF strategies emphasize the importance of: Female education since children of uneducated mothers are twice as likely to die in infancy; Family spacing to reduce infant mortality rates; and Food supplements for at-risk mothers to lower the risk of low birthweight babies.
