Values are means±SD.

Higher scores indicate more improper eating behaviour in terms of a higher probability of obesity: Cognition of weight and constitution, having false recognition of and assumptions about reasons for weight gain; Motivation for eating, having behavioural factors which can induce over-eating; Eating as a diversion, being subject to psychological factors which increase appetite (ie, perceived mental stress); Feeling of satiety, being prone to have an appetite and to eat as much as possible; Eating style, being prone to eat fast; Meal contents, having a preference for a high fat diet and sweets (eg, confectioneries and sweet buns); Temporal eating patterns, irregularity of timing and number of meals taken during the day and delay in timing of meals.
