Tests for linear trend in log odds of exceeding heavy episodic drinking thresholds: adjusted excess odds ratios of moving down one SES level, 2008–2013 (95 % CI; p-value)

	48 g+/64 g+	96 g+/128 g+	144 g+/192 g+	192 g+/256 g+
Income	0.91 (0.89–0.93;<0.001)	0.98 (0.95–1.01; 0.187)	1.03 (0.98–1.09; 0.242)	1.03 (0.94–1.13; 0.560)

Occupation	0.97 (0.95–0.98;<0.001)	1.03 (1.01–1.05; 0.004)	1.07 (1.03–1.10;<0.001)	1.10 (1.05–1.16;<0.001)
Deprivation	0.99 (0.97–1.01; 0.192)	1.05 (1.02–1.08;<0.001)	1.14 (1.09–1.20;<0.001)	1.19 (1.10–1.30;<0.001)

Adjusted for age, sex, ethnicity and year of survey

‘Other’ categories were excluded from education and occupation

Note that SES indicators have different numbers of levels. For example, ‘deprivation’ is based on quintiles, so an excess odds ratio of 1.19 represents an estimated odds ratio of 2.01 comparing bottom and top quintiles. Occupation has eight levels, so an excess odds ratio of 1.10 represents an estimated odds ratio of 1.95 between ‘unemployed’ and ‘higher managerial’

Thresholds are grams of pure alcohol in one day for women/men
