Abstract

Adolescence is a sensitive period throughout the life span.Multiple changes including rapid growth, body shape, social, physiological, psychological and economic aspects, are occurred during the adolescence.Development of personality and lifestyle patterns, including attitudes and behaviours regarding eating takes place at this stage.Adolescents eating behaviours are easily affected by several factors such as parents and peers habits; social relations and school environments.Availability of fast food in schools is another factor that increases its consumption by adolescence.Advertising and marketing by media encourage fast food intake as well.Convenience, taste, delivery services and large portion size of fast food are important factors that have a direct impact on purchasing decision and consumption among adolescence.
