Television, computer use, physical activity, diet and fatness in Australian adolescents.

Purpose: To examine sedentary behaviours (including television viewing, playing computer games and computer use), diet, exercise and fitness in relation to overweight/obesity in Australian adolescents.

Methods: Questionnaires elicited food frequency data, time spent in TV-viewing, using computers, other sedentary occupations and physical activity recall. Weight, height and fitness (laps completed in the Leger test) were measured.

Alcohol expectancies in late childhood: an ambivalence perspective on transitions toward alcohol use.

Background: Late childhood has been identified as a critical transition period in expectancies about alcohol use, but much previous theorising has been based on the assumption that the transition involves a simple shift from negative to positive. This paper addresses the possibility that young people entertain more complex alcohol-related expectancies, and are increasingly aware of both negative and positive consequences of consumption.

Method: Expectancies were measured in a sample of 233 primary school children aged 8, 10, and 12 years.
