Association of IQ at 11 years and life course socioeconomic position with alcohol hangovers in middle aged men and women (n = 5780)
| Model A | Model B | Model C | |
|---|---|---|---|
| *Odds ratios for IQ are for a one SD advantage in score. †Odd ratios for sex are for female compared with male. Odds ratios for remaining (socioeconomic) factors are per unit advantage in: father’s occupational social class at birth of subject (categorised as: unemployed; unskilled; semi-skilled; skilled manual; skilled non-manual; professional); number of siblings at time of original survey in 1962 (⩾4; 3; 2; 1); housing tenure at 12 years of age (other; rented from council; rented privately; owned); car ownership at 12 years of age (no car; ⩾1); educational attainment by age 44–52 years of age (CSE and below; O levels; A levels/highers; teaching/nursing qualification; university degree); housing tenure at 44–52 years of age (rent free/other; renting; owned); car ownership at 44–52 years of age (no car; 1; ⩾2); occupational social class at 44–52 years of age (unskilled; partly skilled; skilled manual; skilled non-manual; professional/managerial) and income at 44–52 years of age (<£10000; £10–<20000; £20–<20000; ⩾30000 per annum). In Model A the relation of each factor to adult hangovers is unadjusted. In Model B the relation of sex and early life factors to adult hangovers are mutually adjusted. In Model C the relation of all factors to adult hangovers are mutually adjusted. | |||
