Objective: To discover whether eating behaviour traits show continuity and stability over childhood. Subjects/Methods: Mothers of 428 twin children from the Twins Early Development Study participated in a study of eating and weight in 1999 when the children were 4 years old. Families were contacted again in 2006 when the children were aged 10 years, with complete data on 322 children; a response rate of 75%. At both times, mothers completed the Child Eating Behaviour Questionnaire (CEBQ) for each child. Continuity was assessed with correlations between scores at the two time points, and stability by changes in mean scores over time.Results: For all CEBQ subscales, correlations between the two time points were highly significant (P-values o0.001). For satiety responsiveness, slowness in eating, food responsiveness, enjoyment of food, emotional overeating and food fussiness, correlations ranged from r ¼ 0.44 to 0.55, with lower continuity for emotional undereating (r ¼ 0.29). Over time, satiety responsiveness, slowness in eating, food fussiness, and emotional undereating decreased, while food responsiveness, enjoyment of food and emotional overeating increased. Conclusions: Eating behaviours, including those associated with a tendency to overeat, emerge early in the developmental pathway and show levels of individual continuity comparable to stable personality traits. Appetitive traits related to higher satiety tended to decrease with maturation, while those associated with food responsiveness tended to increase. This pattern is consistent with strong tracking of body mass index alongside a progressive increase in the risk of obesity.

With overdose management training, opiate users can be trained to execute appropriate actions to assist the successful reversal of potentially fatal overdose. Wider provision may reduce drug-related deaths further. Future studies should examine whether public policy of wider overdose management training and naloxone provision could reduce the extent of opiate overdose fatalities, particularly at times of recognized increased risk.

EAH is a behavioural phenotype that is not specific to overweight children but instead shows a graded association with adiposity across the weight continuum, particularly in boys. In this study, the effect was less pronounced in girls, which may reflect social desirability pressures constraining food intake among heavier girls.
