8% of all children in foster care have serious emotional problems, 11% of children exiting foster care aged out of the system, in 2011. Children in foster care experience high rates of child abuse, emotional deprivation, and physical neglect. In one study in the United Kingdom "foster children were 7–8 times, and children in residential care 6 times more likely to be assessed by a pediatrician for abuse than a child in the general population". A study of foster children in Oregon and Washington State found that nearly one third reported being abused by a foster parent or another adult in a foster home. The "Parent Trauma Response Questionnaire" states that parental overprotection can be just as harmful psychologically as neglect. Development
As of 2019, the majority of children in the foster care system were under 8 years of age. These early years are quite important for the physical and mental development of children. More specifically, these early years are most important for brain development. Stressful and traumatic experiences have been found to have long-term negative consequences for the brain development in children whereas talking, singing, and playing can help encourage brain growth. Since the majority of children are removed from their homes due to neglect, this means that many of these children did not experience stable and stimulating environments to help promote this necessary growth.
Adults
GH treatment can confer a number of measurable benefits to severely GH-deficient adults, such as enhanced energy and strength, and improved bone density. Muscle mass may increase at the expense of adipose tissue. Although adults with hypopituitarism have been shown to have a reduced life expectancy, and a cardiovascular mortality rate of more than double controls, treatment has not been shown to improve mortality, although blood lipid levels do improve. Similarly, although measurements of bone density improve with treatment, rates of fractures have not been shown to improve.Effects on quality of life are unproven, with a number of studies finding that adults with GHD had near-normal indicators of QoL at baseline (giving little scope for improvement), and many using outdated dosing strategies. However, it may be that those adults with poor QoL at the start of treatment do benefit. Epidemiology
The incidence of idiopathic GHD in infants is about 1 in every 3800 live births, and rates in older children are rising as more children survive childhood cancers which are treated with radiotherapy, although exact rates are hard to obtain. The incidence of genuine adult-onset GHD, normally due to pituitary tumours, is estimated at 10 per million.
