Infants raised in early child care institutions in the 1950s [1] have a significantly shorter life expectancy than the general population.
This finding suggests that the first few years of life create a biological blueprint that affects health and survival for decades. The research highlights how the absence of fundamental emotional bonds can lead to permanent physiological vulnerabilities.
The study focused on a specific group of individuals who grew up in care institutions in Zurich [2]. By tracking these individuals over several decades, researchers were able to compare their longevity against those who were not institutionalized during their infancy.
According to the research, the primary drivers of this reduced lifespan are the deprivation of affection and stimulation during critical developmental windows. These early experiences are not merely psychological hurdles but factors that influence long-term physical health outcomes [1].
"Infants who grew up in early child care institutions in the 1950ss have a much shorter life expectancy than the general population," a researcher said [1].
The data suggests that the impact of this early environment persists regardless of later interventions or improvements in living conditions. The study emphasizes that the biological toll of early neglect is profound and enduring.
"For the first time, the study provides robust evidence that early deprivation of affection and stimulation has serious consequences across the life span," a researcher said [1].

This study provides empirical evidence for the 'critical period' hypothesis in human development, suggesting that emotional and sensory deprivation in infancy can infancy can cause systemic biological changes. By linking 1950s institutional conditions in Zurich to adult mortality, the research underscores the necessity of high-quality, affectionate care in early childhood to ensure long-term health and longevity.
