Article Synopsis
- Early-life parental factors, including positive personality traits and stress levels, significantly shape the environment for child development and can influence sleep health in children.
- The study involved 351 families from the Arizona Twin Project, assessing parental characteristics and children's sleep duration when the twins were both 12 months and 8 years old.
- Findings indicate that a more positive parental personality can reduce the genetic influence on sleep duration, while increased parental stress enhances genetic contributions, suggesting that both genetic and environmental factors play key roles in children's sleep health.

Article Synopsis
- Premature infants face potential long-term challenges like lower effortful control, which can negatively impact academic achievement, peer relationships, and overall wellness throughout their lives.
- The study investigates the interactions between genetics, early birth, and complications at birth to understand their effects on the development of effortful control from 12 months to 10 years using data from a twin cohort in Arizona.
- Results indicated that effortful control, particularly attentional focus, is strongly influenced by genetics rather than gestational age or early complications, highlighting the different origins of each subdomain of effortful control.
