  • *This includes all current drinkers who reported weekly alcohol units of >21 units for men and >14 units for women.

  • The P value (two-sided) is from the likelihood ratio test for heterogeneity in the probability of consuming over the recommended weekly alcohol units across different levels of the specified explanatory factor with adjustment for all other factors in the multivariable model, using only the current drinkers. The threshold for statistical significance was 0.01.

  • The Ptrend is from the test for trend and the P value in parentheses is from the test for departure from a linear trend. Both P values are two-sided. The threshold for statistical significance was 0.01.

  • §This is not all current drinkers (n = 8,024) due to missing alcohol units for 51 survivors.

  • These values do not equal the total because of exclusion of those with no record of treatment (radiotherapy n = 2,089) and unusable or missing data (legal marital status: missing data, n = 174; whether receiving long-term regular hospital follow-up: missing data, n = 249; general health perception score: missing data, n = 139; mental health score: missing data, n = 162).

  • Information obtained from the consent form returned from the general practitioner, which asked whether the survivor was receiving long-term regular hospital follow-up in relation to his/her childhood neoplastic disease.

  • **The score categories were for general health perception (low, 0-32; moderate, 33-76; high, 77-100) and mental health (low, 0-52; moderate, 53-75; high, 76-100).
