Abstract

Gene-environment correlations and interactions for the relationship between emotional problems (EP) and family environment in adolescents in low- to middle-income countries (LMIC) have been rarely investigated. In total, 3207 adolescent twins aged 12–18 (Mean = 14.6 ± 1.73) years attending public schools in Lagos State in Nigeria completed measures of EP and Family Chaos (FC). Model-fitting analyses suggested that genetic and non-shared environmental influences on EP were 21% and 71%, respectively, and the corresponding estimates were 23% and 71% for FC. Shared environmental influences were not significant (8% and 6% respectively). Phenotypic correlation between EP and FC was .30 (95% CI = .27–.34), which was significantly influenced by genetic (A – 49%, 95% CI: 0.01–0.97) and non-shared environmental factors (E – 32%, 95% CI: 0.10–0.54). Shared environmental influences were not significant (C – 19%, 95% CI: −0.13 to 0.50). Moderation effects were significant whereby as FC increased, A on EP decreased (βA = −0.07, 95% CI: −0.12 to −0.02) while E increased (βE = 0.06, 95% CI: 0.03–0.09). Our findings indicate that genetic and non-shared environmental risk factors may mediate the relationship between EP and FC, and that as FC increases, protective genetic influences on EP may be attenuated, whereas environmental influences may become stronger in adolescents in LMIC.
