The teenage alcohol drinking in 1980 is described in a cohort of 12,058 subjects born in Northern Finland in 1966, with special reference to non-standard families (with one or both parents absent). The percentage of boys (girls) who had been drinking alcohol at the age of 14 years, was 59.1 (58.3)%, being 57.5 (55.6%) in standard, full families and 66.0 (69.0)% in non-standard families. The percentage of having been drunk was 25.2 (25.1)%, or 22.8 (22.1)% in full families and 36.1 (37.1)% in the non-standard families. When adjusted for the maternal age at birth, place of residence, social class and child's status in the family (firstborn or not, only child or not) by means of regression modelling, the risk of alcohol drinking/having been drunk was still increased in non-standard families, especially in cases of divorce or same-sex parental death, the risk differences as compared to the standard family usually being between 10-20%. The results suggest that a non-standard family structure is associated with early juvenile alcohol drinking. Parental loss or absence may constitute one important factor leading to excessive haste in adopting the adolescent culture, including its potentially destructive habits.
