One of six information booklets with accompanying training materials for the Medicaid Early and Periodic Screening Diagnosis and Treatment (EPSDT) program, this booklet describes the stages of child growth and development and some of the health problems which EPSDT clients might have. Section I describes tests commonly included in an EPSDT screening program. Section II overviews five stages of child growth and development: pregnancy, infancy, early childhood, childhood and adolescence. Child safety considerations are emphasized and issues faced during adolescence are discussed. Section III indicates the pattern of non-use of health care systems among EPSDT clients and provides guidelines for establishing a good relationship between parents and their child's doctor. Section IV discusses selected health problems which EPSDT clients are likely to have and about which EPSDT workers may want information. Health problems in the following categories are defined: anemia, child abuse, dental health, diabetes, hearing and speech, high blood pressure, immunization, lead poisoning, malnutrition, obesity, parasites, rheumatic fever, sickle cell conditions, skin problems, substance abuse, tuberculosis, venereal disease, vision. Treatment procedures and implications for the EPSDT worker are indicated. Section V lists selected references. (Author/RH)
