Aims

We have set three aims, split into sub-objectives:

1 To study underage drinking and heavy drinking episodes in childhood and adolescence:

1.1 To describe the consumption and patterns of alcohol use in youth, investigating possible biases due to drop outs and the accuracy of their reporting;

1.2 To describe changes and trajectories of alcohol use during development;

2 To analyse the social-patterns of alcohol consumption in a parental adult population:

2.1 The frequency, intensity and typology of drinking across different time-points and how they relate with socio-economic position will be addressed;

3 To investigate the role of socio-economic factors and parental exposures on early or heavy episodic alcohol use in young people:

3.1 The relative influence of family income, parental occupation and education and family financial strain on alcohol use in young people;

3.2 The association between parental use of alcohol and alcohol use in the young person.
