It is fundamental to understand how adolescents perceive their parents and peers behaviour and stimulus to adolescents own behaviour. This research aimed to study the perception Portuguese adolescents have about their parents and peers behaviour and the stimulus to adolescents own physical activity and eating behaviour.

Adolescents also perceive parents to encourage them to have healthy diets always/almost always (93,9% mothers; 88,0%fathers) and to be physically active always/almost always (86,3% mothers; 88,8%fathers). A Cohen’s kappa moderate consistency among perception of fathers and mothers stimulus was found either to healthy diet (0.47; p <0.001), and physical activity (0.42; p <0.001); and between perception of peers stimulus and behaviour (0.45; p
