Eraction for hard physical exercise (Wald 2 [2] = three.60, p = .165). The interaction impact for worldwide consuming disorder symptoms is summarised in Figure 1. Girls with elevated depressive symptoms at age 14 had larger scores at every time point than girls devoid of depressive symptoms at age 14, but scores remained steady involving age 14 and age 20 for the depressive symptom group, whereas they increased over time for the non-depressed group. Interaction effects for the categorical variables are summarised in Figure two. Girls with depressive symptoms at age 14 had higher prevalence prices for every eating disorder symptom at every time point, together with the exception of dietary rules at age 20. Even so, rates for binge eating, fasting, and dietary guidelines decreased by about 10 from age 14 to age 20 for this group, and rates for purging increased from at age 14 to age 17 but then decreased to approximate 14-year levels at age 20. For girls without having depressive symptoms at age 14, prices for binge consuming, purging, fasting and dietary rules increased over time (see Figure 2).Discussion This study has described the prevalence and trajectory of eating disorder symptoms in male and female adolescents followed from 14 to 20 years of age. Symptom trajectories varied based on the distinct consuming disorder symptom studied, participant sex, and the presence of depressive symptoms in early adolescence. For boys, consuming disorder symptoms tended to become steady (for purging, fasting and hard physical exercise) or decreasing (for global eating disorder symptom scores and binge consuming) from 14 to 17 years, then steady to 20 years. An exception was discovered for strict dietary rules, where prevalence decreased from age 14 to age 17 just before increasing to baseline levels by age 20. These results are consistent with findings from the small quantity of preceding research with adolescent males [3,5,8], which observed steady or minimizing symptoms from early to middle adolescence, prior to a rise in symptoms in late adolescence or early adulthood. In this sample, we didn’t observe marked increases in eating pathology in late adolescence, suggesting that any increases within this cohort did not occur until soon after age 20. It’s intriguing to note that the 1 symptom that did boost in late adolescence was attempts to stick to strict dietary guidelines. Cognitive-behavioural theories would recommend that an increase in strict dieting could precede a subsequent boost in binge consuming, and possibly purging [22,49]. This makes it possible for for the hypothesis that male participants in this sample are at risk for these behaviours as they move in to early adulthood. Boys who reported depressive symptoms at age 14 had larger prices of all eating disorder symptoms, on average, than boys who didn’t report marked depression at age 14. However, depression at age 14 didn’t relate considerably to symptom trajectories over the following 6 years.Figure 2 Prevalence rates (with 95 confidence intervals) for categorical eating disorder symptoms in girls, by time and 14-year depression status.
