Mothers and fathers of twin babies conceived through ART show higher rates of depression, anxiety, and social dysfunction compared to parents of singletons. Counselling and preparation before birth may play a role in mitigating these effects.
A study of over 7,600 Swedish twins found that genetic factors and the individual's unique environment play a significant role in determining their choice of sexual partner. The results suggest that familial and public attitudes have a minimal impact on this decision.
A recent study found that genetic risk factors for common fears, such as situational or blood-injury phobias, decline in importance during childhood and adolescence. However, new genetic influences emerge during early adolescence, late adolescence, and adulthood, suggesting a dynamic relationship between genetics and fear.
A new study led by Virginia Commonwealth University researchers found that genetic factors play a crucial role in shaping how individuals choose their peer groups. The study suggests that genes become increasingly important as individuals develop, potentially influencing their risk for future substance use or deviant behaviors.
A Finnish study found that persistent smokers are at a higher risk of developing depressive symptoms compared to never smokers. In contrast, those who successfully quit smoking tend to experience elevated depressive symptoms in the short term, but this risk declines over time.
A study published in Archives of Ophthalmology found that smoking increases the risk of Age-related Macular Degeneration (AMD), while a higher intake of fish and omega-3 fatty acids reduces the risk. The research, conducted on 681 male twins, highlights the importance of prevention over limited treatment options for AMD.
A study found that improving education on the risks of twins improved IVF patients' understanding and reduced their desire for multiple births. However, despite increased knowledge, many patients still prefer to have twins due to a desire to complete their family quickly with minimal treatments.
