A Father's Involvement in the First Year of a Child's Life Affects Future Health 0 10

Unlike traditional surveys, the authors of the study employed direct observation and biochemical analysis methods. They visited families when the children were ten and 24 months old, recording 18-minute episodes of joint play, assessing the warmth of reactions, responsiveness to the child's needs, and the quality of parenting.

Then, at the age of seven, blood samples were taken from the children to measure levels of cholesterol, glycated hemoglobin, interleukin-6, and C-reactive protein. It turned out that the father's behavior in infancy was most strongly associated with the child's future metabolic health: sensitivity at ten months correlated with normal blood indicators at seven years, while its absence was linked to elevated levels of inflammation markers and problems with sugar regulation.

The researchers were surprised by the results: traditionally, the mother was assigned a key role in the family, but her warmth did not have such a significant connection with physical blood markers in the long term. Professor Hanna Shrier noted that a father's behavior before the child develops stable memories can influence their health by the second grade.
