Study Reveals the Ideal Number of Children for a Woman's Longevity.

How Family Size Affects Women's Lifespan

According to TSN.ua: Research from the University of Helsinki indicates that the number of children a woman has significantly influences her lifespan and biological aging. The most favorable outcomes were observed in women who had two or three children and became pregnant between the ages of 24 and 38. Conversely, the worst indicators were found in women with no children and those with an average of 6.8 children.

The study involved 14,836 women, all of whom were twins, allowing researchers to account for genetic factors that might affect the results. In a subgroup of 1,054 participants, specific markers of biological aging were also assessed, providing more precise data.

Key Findings of the Research

Participants were divided into seven groups based on the number of children and the timing of their births. The poorest biological aging markers were identified in women with no children and those with an average of 6.8 children. This suggests that both insufficient and excessive numbers of children can negatively impact health. This type of twin study is particularly valuable for separating environmental influences from genetic predispositions.

“A person who is biologically older than their calendar age faces a higher risk of mortality.”

These findings underscore the importance of considering reproductive factors in women's health research. Understanding the optimal number of children could have significant implications for public health policy, social security, and family planning. The study may serve as a foundation for further scientific inquiry into the complex relationship between reproductive choices and women's overall well-being.
