Sukupolvivaikutukset

Sukupolvivaikutukset, translated as intergenerational effects or generational impacts, refer to the ways in which the circumstances, health, behaviors, and environmental exposures of one generation influence the outcomes of subsequent generations. These effects can be biological, psychological, social, or economic, and they are studied across fields such as epidemiology, sociology, developmental psychology, and genetics.

Biologically, epigenetic mechanisms provide a plausible pathway for some intergenerational transmission. Environmental factors such as nutrition, stress, or toxin exposure can cause chemical modifications to DNA that do not change the genetic sequence but can affect gene expression. Some of these epigenetic marks are retained after reproduction and may alter the phenotype of offspring. Research on animal models, and increasingly in humans, has linked parental diet and stress to metabolic and mental health outcomes in children.

Socially and economically, parental education, income, and health behaviors shape the materials and opportunities available to children. The “social determinants of health” framework notes that wealth and education differences are largely reproduced across generations through marriage patterns, schooling opportunities, and access to health care. Programs aimed at improving early childhood education or parental support can thus yield long‑term benefits that extend beyond the immediate cohort.

In public health, the concept of sukupolvivaikutukset is used to justify investments in prenatal care, maternal nutrition, and early childhood interventions. By recognizing that positive changes in one generation can reduce disease burden and inequality in future generations, policymakers argue that preventive measures confer an intergenerational return on investment.
