In 1989, when the Ceausescu regime fell in Romania, foreign families streamed in to adopt many of the nation’s children that had been abandoned in institutions. This was the start of an era of significant growth in intercountry adoption that included many countries in the former Soviet Union and Eastern and Central Europe. The opening of these once closed societies provided researchers with unprecedented opportunities to study child development and early childhood adversity through the impact of children living in institutions. Intercountry adoption in the region provided a unique group of children for study, children that had lived in institutions for various periods of time at different ages in their development and were later adopted. Researchers have also been able to assess children placed in foster care from institutions and those receiving new forms of care within institutions.
This paper briefly summarizes four distinct sets of research on the impact of institutionalization on children. Three are seminal studies specific to the CEE/CIS1 region, covering a wide range of issues in child development. The fourth is a set of meta-analyses based on thousands of adopted children worldwide. Consistent with these studies are new and important findings on the brain development of children. The findings of these and other similar research studies are many, and can be pursued by further studying the resources highlighted in the appendix to this paper. However, one inescapable conclusion is clear from the research highlighted here: for the sake of their development and wellbeing, it is of the utmost importance for young children to be in nurturing family-based environments early in their young lives.The English and Romanian Adoption Study (ERA)2 focuses on 165 Romanian children adopted by English families in the early 1990s. The children are grouped according to their age at the time of their adoption, and then assessed at later ages in their lives. This study is representative of children coming from severely deprived institutional care into family permanency in a country with an advanced social service system. ERA findings include:
The Bucharest Early Intervention Project (BEIP)3 is the first-ever randomized study of foster care as an alternative to institutionalization and a form of intervention to address the deprivation associated with institutional care. The BEIP research began in 2000. Half of the 136 institutionalized children studied were placed in high-quality foster care. One aspect of this research involved measuring the electrical brain activity of children through electroencephalograms (EEGs). Key findings include:
The St. Petersburg-USA Orphanage Team Research project4 studied three baby homes in St. Petersburg, beginning in 2000. The baby homes met reasonable medical and nutritional standards, but children there clearly lacked strong socio-emotional relationships with their caregivers. As part of the project, caregivers were offered training in early childhood development and mental health, emphasizing the need for responsive and developmentally appropriate childcare. Structural changes were also implemented, which included a reduction in the number of children cared for by each caregiver, the promotion of interactive “family time” play, and fewer changes in caregivers for children. This was intended to provide more family-like care. Close to 1,000 children and over 500 caregivers have been involved in the study. Findings include:
Meta-analyses are research projects in which results of other studies published on the same topic are combined. After reviewed and selected for quality, this pooled data can provide strong evidence from which to draw conclusions. Most of the results below are drawn from social scientists associated with Leiden University5 in the Netherlands, who specialize in research based on thousands of adopted individuals worldwide, many of them adopted from residential care
Historically, institutions in the CEE/CIS region have been established to provide children with the basic needs of food, medical care, shelter, and education. This is also true for many institutions in other developing regions of the world.
Measuring physical growth is, of course, a common means to assess development of children. It is clear, however, that factors beyond disease and the lack of nutrition can inhibit growth. “Psychosocial growth failure” is a term that reflects the additional adversity experienced by children that can contribute to failure in growth. For young institutionalized children, this adversity comes from the lack of attentive and nurturing care that normally comes from parents.7 For example, the feeding of infants requires close personal attention as opposed to propping up a bottle. An infant with disabilities may require specialized feeding. Unfortunately, many institutions lack the budgets and the staff necessary to perform these functions
Growth suppression in adversity – and eventual recovery with nurturing care – is found in all the research concerning children that have been institutionalized. The St. Petersburg-USA Orphanage Team Research confirms this, in that enhanced social and emotional support by caregivers resulted in improved growth for infants and young children, without any changes in their nutrition.
Overall growth failure is linked, to varying degrees, with cognitive, emotional, and behavioral challenges. As the English and Romanian Adoption Study demonstrates, if an institutionalized child is placed in family-like care within six months of age, the risk of early and persistent growth failure is significantly lowered.
Profound changes occur in the brain early in a child’s life as important neural foundations are built. But it is difficult to study the brain and its functioning in relation to the impact of institutionalization, due to the timing challenges of assessing brains before, during, and after potentially sensitive periods of brain development within different care environments. Additionally, the brain is known to adjust and compensate for deficits in ways that are difficult to measure, let alone fully understand.
Neurons in the brain connect via synapses, enabling crucial circuitry development in the brain. Neurons and synapses experience great growth in the prenatal period, to the point of overproduction. This process is controlled through genetics, though adversity during pregnancy – such as fetal exposure to alcohol – can have a negative impact.8 “Pruning back” and shaping this overproduction begins after a child is born. The central nervous system changes and adapts in response to environmental cues, experience, behavior, injury, or disease. A great deal of this brain shaping occurs in the early months and years of a child’s life. Thus, the deprivation experienced by institutionalized children early in their lives can negatively impact their brain circuitry development
Decreased head circumference is associated with psychosocial growth failure in young children who have been institutionalized, though there is an opportunity for the child to catch up to normal measurements if placed in a nurturing environment early in life. Additional information can be found in studies on the brain’s chemical/hormonal functioning, in anatomical images, and through neuro-psychological testing to better understand what happens in a child’s brain as a result of adversity caused by institutional care.
Growth hormone production begins in the pituitary gland, situated at the base of the brain, upon stimulation from the hypothalamus. Growth hormone, which is important for cognitive development as well as for growth, is converted into other active products in the liver, and is excreted primarily by the kidneys. This system can be altered if psychosocial growth failure is experienced.
Strong, frequent, and/or prolonged abuse leads to a condition known as “toxic stress.”9 Abnormal levels of stress hormones, such as cortisol, can disrupt brain development in young children, and affect other organ systems as well. It can also negatively impact growth. Research links early toxic stress with poor cognitive and emotional functioning well into the adult years.
Studies of children who have lived in institutions have shown higher and lower levels of cortisol in the children at various times of the day. This has been found in children with a history of institutional care adopted from Romania, Russia, and China, and has also been found in youth in the U.S. who suffered physical neglect prior to their placement in foster care.10 Studies of adopted children coming from particularly adverse institutional environments show that they may have higher cortisol levels for years if they are not placed in nurturing family care by 4-6 months of age.11
A number of brain imaging procedures shed further light on the impact of institutionalization on early childhood development. The EEG findings of the Bucharest Early Intervention Project are verified by an additional study on children adopted from Asia.12 Another imaging procedure, Positron Emission Tomography (PET), enables images and measurements of metabolism of different brain regions. When applied to Romanian adoptees institutionalized for an average of about three years, one PET study13 showed that their metabolism was significantly reduced in brain regions involved with higher cognitive functions, memory, and emotion – and this was linked to impulsivity, attention disorder, and social deficits.
Magnetic Resonance Imaging (MRI)14 has been performed on children that faced institutional deprivation early in their lives. Studies show images of diminished brain “white matter” that connects areas involved in higher cognitive and emotional functioning, which normally grows dramatically in the period before three years of age. Amygdalae15 in the brains of institutionalized children have been shown to have differing sizes compared to never-institutionalized children, as seen in the English and Romanian Adoption Study and another study of adoptees mostly from China.16
The above studies and others provide clear evidence that the early institutionalization of young children can have a number of harmful impacts on the brain, by
The diversity of studies of the brain brings us a depth of knowledge on how and why institutional care is so damaging for children. The English and Romanian Adoption Study shows that it is critical to place children in a nurturing family care environment before six months of age, such as through adoption. The Bucharest Early Intervention Project demonstrates the importance for children of alternative systems such as quality foster care, though this needs to happen very early in a child’s life for the strongest impact. The St. Petersburg-USA Orphanage Team Research confirms that, for children in residential care awaiting a safe and nurturing family – including the large number of institutionalized children that are disabled – the quality of care can be improved and lead to significant gains in child development.
Finally, the meta-analyses of thousands of adopted children is a testament to the resiliency of children that have been given the opportunity to be cared for and nurtured in permanent, loving families. Many children available for international adoption are older, and many infants cannot be easily adopted before the age of six months due to the nature of intercountry adoption. Yet even among children adopted at older ages, there is a great deal of variability in their outcomes, and the majority of children thrive in their adoptive families.
The severity of deficits and pace of recovery is different for each child who has experienced institutionalization, depending on a child’s prenatal and/or after-birth experience in a family and the adversity experienced prior to residential care. Genetics also plays an important, but not yet well understood, role. Conditions in institutions vary widely in size, training, operational methods, and financial resource availability, all of which have a bearing on child development. As a result, researchers agree that more study is needed on the topics covered in this paper.
It is clear, however, that the sum total of the research establishes a most compelling and urgent humanitarian need for the youngest of children to be saved from the adverse impact of institutionalization. Sensitive developmental periods during which a child needs nurturing care come very early and span a broad array of functions related to physical, cognitive, emotional, and behavioral wellbeing.
Family-based alternatives provide a far better environment for child development and often prove to be cost-effective when compared to institutional care. Along with efforts to strengthen adoption and foster care programs, stronger support services must be provided to struggling families so that children can remain with their families in a safe and healthy environment. A care model centered on institutions is simply too risky a gamble for orphaned, abandoned, and vulnerable children.

1 The CEE and CIS countries are those former communist states in Central and Eastern Europe (CEE), and countries formerly in the Soviet Union (many now members of the Commonwealth of Independent States, CIS). They constitute a region in the sense in that they share many of the same characteristics in their transitions, including their child welfare systems.
