Psychosocial factors in childhood are associated with worse midlife learning and memory: Study

Dec 05, 2022

Washington [US], December 5 : A new Finnish study has found that cumulative adverse psychosocial factors in childhood are associated with worse midlife learning and memory, and specifically child's self-regulation and social adjustment.
The study was published in the journal, 'Neuropsychology'.
Along with aging population, the prevalence of cognitive deficits is growing. Thus, revealing the role of various exposures beginning from childhood is important in order to bring tools for cognitive health promotion. An adverse psychosocial environment in childhood may harm cognitive development, but the associations for adulthood cognitive function remain obscure. Results from a longitudinal Finnish study show that unfavourable childhood psychosocial factors may link to poorer learning and memory in midlife.
"Previous evidence on adverse psychosocial factors and cognitive outcomes comes mainly from either short-term or retrospective long-term studies focusing on single psychosocial factor or adversity. This study is one of the first prospective longitudinal studies focusing on the associations between multiple childhood psychosocial factors and adulthood cognitive function," says Doctoral Researcher Amanda Nurmi from the Centre for Population Health Research at the University of Turku and Turku University Hospital.
Cognitive performance was measured at the age of 34-49 years. Of over 2,000 participants with cognitive function data, 1,191 also had complete data on childhood psychosocial factors from childhood. Socioeconomic and emotional environment, parental health behaviours, stressful events, self-regulation, and social adjustment were queried in the baseline. The results suggest that accumulation of unfavorable psychosocial factors in childhood may associate with poorer cognitive function in midlife. Specifically, poor self-regulatory behaviour and social adjustment in childhood are associated with poorer learning ability and memory approximately 30 years later.
"The results of our study can be leveraged to develop targeted interventions directed towards those families with cumulative adverse psychosocial factors. Interventions towards promoting a better psychosocial environment in childhood might have carry-over associations on cognitive function and thus be also reflected in future generations via parenting attitudes," Nurmi says.
