The role of common genetic variation in educational attainment and income: evidence from the National Child Development Study.

ABSTRACT: We investigated the role of common genetic variation in educational attainment and household income. We used data from 5,458 participants of the National Child Development Study to estimate: 1) the associations of rs9320913, rs11584700 and rs4851266 and socioeconomic position and educational phenotypes; and 2) the univariate chip-heritability of each phenotype, and the genetic correlation between each phenotype and educational attainment at age 16. The three SNPs were associated with most measures of educational attainment. Common genetic variation contributed to 6 of 14 socioeconomic background phenotypes, and 17 of 29 educational phenotypes. We found evidence of genetic correlations between educational attainment at age 16 and 4 of 14 social background and 8 of 28 educational phenotypes. This suggests common genetic variation contributes both to differences in educational attainment and its relationship with other phenotypes. However, we remain cautious that cryptic population structure, assortative mating, and dynastic effects may influence these associations.

Project description:ObjectiveTo determine if first trimester maternal thyroid dysfunction is a critical determinant of child scholastic performance and overall educational attainment.DesignProspective cohort study.SettingAvon Longitudinal Study of Parents and Children cohort in the UK.Participants4615 mother-child pairs with an available first trimester sample (median 10 weeks gestation, interquartile range 8-12).ExposuresFree thyroxine, thyroid stimulating hormone, and thyroid peroxidase antibodies assessed as continuous measures and the seven clinical categories of maternal thyroid function.Main outcome measuresFive age-specific national curriculum assessments in 3580 children at entry stage assessment at 54 months, increasing up to 4461 children at their final school assessment at age 15.ResultsNo strong evidence of clinically meaningful associations of first trimester free thyroxine and thyroid stimulating hormone levels with entry stage assessment score or Standard Assessment Test scores at any of the key stages was found. Associations of maternal free thyroxine or thyroid stimulating hormone with the total number of General Certificates of Secondary Education (GCSEs) passed (range 0-16) were all close to the null: free thyroxine, rate ratio per pmol/L 1.00 (95% confidence interval 1.00 to 1.01); and thyroid stimulating hormone, rate ratio 0.98 (0.94 to 1.02). No important relationship was observed when more detailed capped scores of GCSEs allowing for both the number and grade of pass or when language, mathematics, and science performance were examined individually or when all educational assessments undertaken by an individual from school entry to leaving were considered. 200 (4.3%) mothers were newly identified as having hypothyroidism or subclinical hypothyroidism and 97 (2.1%) subclinical hyperthyroidism or hyperthyroidism. Children of mothers with thyroid dysfunction attained an equivalent number of GCSEs and equivalent grades as children of mothers with euthyroidism.ConclusionsMaternal thyroid dysfunction in early pregnancy does not have a clinically important association with impaired child performance at school or educational achievement.

Project description:ObjectiveSocial determinants contribute to adverse outcomes in cardiovascular and non-cardiovascular conditions. However, their investigation in atrial fibrillation (AF) remains limited. We examined the associations between annual income and educational attainment with risk of hospitalization in individuals with AF receiving care in a regional health care system. We hypothesized that individuals with lower income and lower education would have an increased risk of hospitalization.MethodsWe enrolled a cohort of individuals with prevalent AF from an ambulatory setting. We related annual income (≤$19,999/year; $20,000-49,000/year; $50,000-99,999/year; ≥$100,000/year) and educational attainment (high school/vocational; some college; Bachelor's; graduate) to hospitalization events in multivariable-adjusted Cox proportional hazards models, using the Andersen-Gill model to account for the potential of participants to have multiple events.ResultsIn 339 individuals with AF (age 72.3 ± 10.1 years; 43% women) followed for median 2.6 years (range 0-3.4 years), we observed 417 hospitalization events. We identified an association between both income and educational attainment and hospitalization risk. In multivariable-adjusted analyses which included educational attainment individuals in the lowest annual income category (≤19,999/year) had 2.0-fold greater hospitalization risk than those in the highest (≥100,000/year; 95% Confidence Interval [CI] 1.08-4.09; p = 0.03). In multivariable-adjusted analyses without adjustment for income, those in the lowest educational attainment category (high school/vocational) had a 2-fold increased risk of hospitalization relative to the highest (graduate-level; 95% CI 1.12-3.54, p = 0.02). However, this association between education and events was attenuated with further adjustment for income (95% CI 0.97-3.15, p = 0.06).ConclusionsWe identified relationships between income and education and prospective risk of hospitalization risk in AF. Our findings support the consideration of social determinants in evaluating and treating socioeconomically disadvantaged individuals with AF to reduce hospitalization risk.
