The largest twin study to date, involving over 21,000 identical twins 👯♂️, found that genetic differences 🧬 influence how individuals respond to their environment 🌍. These gene-environment interactions help explain varying susceptibility to ADHD, autism traits, anxiety 😟, depression 😔, and other conditions.

Research has found growing up in a society with a wide gap between the rich and the poor is linked to higher rates of depressive symptoms later in adulthood. The researchers adjusted for factors like age, sex, and education. Read Full Article #MentalHealth…
⬆️ Growing up in societies with greater economic inequality is linked to higher rates of depressive symptoms in adulthood. This effect is amplified for individuals with a genetic predisposition to depression, suggesting an unequal environment can worsen biological risks.
⬆️ Research published in Psychological Medicine analyzed data from 69,924 participants (twins born 1893-1979) across Australia, Denmark, Sweden, and the US. Childhood income gap was measured by the top 1% income share during ages 5-15.
⬆️ The study found that for men, high childhood inequality and a genetic predisposition for depression led to the most severe symptoms, supporting a gene-environment interaction. For women, genetic risk and inequality independently contributed to depression.
⬆️ In more unequal societies, genetic factors played a larger role in depression. Heritability of depressive symptoms was about 30% in low inequality areas, rising to nearly 37% in high inequality areas, indicating environment influences genetic expression.
