Objective: To investigate age-related trends in bulimic symptoms and associated putative risk factors among Norwegian youth.Method: A sample of 3,150 participants, 1,421 (45.1%) males and 1,759 (54.9%) females, was prospectively followed for 11 years at three time points from adolescence to adulthood. Linear random coefficient models were applied.Results: For females, bulimic symptoms increased from age 14 to 16 and declined slowly thereafter. For males, the symptoms decreased between ages 14 and 16 and returned in the early 20s. Females had higher levels of symptoms than males at every age. Age-associated trends in body mass index, appearance satisfaction, and symptoms of anxiety and depression were associated with some of the trends for both genders. For females, changes in alcohol consumption and cohabitation status functioned as predictors as well.Discussion: Males and females show distinct developmental trajectories of bulimic symptoms during adolescence and in the transition to adulthood. Prevention interventions should focus on putative risk factors in mid-adolescence for females and in the early 20s for males. V V C 2011 by Wiley Periodicals, Inc.

“…26 The striking finding from this study is that the rate of referral to specialist services is close to the level that epidemiological studies suggest is the actual incidence of new cases seen in primary care. 51,361 It is possible that GPs with links to specialist services have better knowledge of EDs and their treatment and therefore identify and refer more cases than GPs with no specialist links. Alternatively, the visibility and easy access to specialist services may encourage referrals rather than a 'wait and see' approach that is sometimes seen in primary care.…”

“…Eating disorders have a high rate of onset during adolescence, 51,52 the period during which young people attend secondary/high school. Research indicates that up to 1.5% of secondary school students suffer from a diagnosable eating disorder [53][54][55] and up to 15% experience subclinical eating disturbance.…”

BackgroundAnorexia nervosa (AN) is a severe psychiatric condition and evidence on how to best treat it is limited.ObjectivesThis programme consists of seven integrated work packages (WPs) and aims to develop and test disseminable and cost-effective treatments to optimise management for people with AN across all stages of illness.MethodsWP1a used surveys, focus groups and a pre–post trial to develop and evaluate a training programme for school staff on eating disorders (EDs). WP1b used a randomised controlled trial (RCT) [International Standard Randomised Controlled Trial Number (ISRCTN) 42594993] to evaluate a prevention programme for EDs in schools. WP2a evaluated an inpatient treatment for AN using case reports, interviews and a quasi-experimental trial. WP2b used a RCT (ISRCTN67720902) to evaluate two outpatient psychological therapies for AN. WP3 used a RCT (ISRCTN06149665) to evaluate an intervention for carers of inpatients with AN. WP4 used actimetry, self-report and endocrine assessment to examine physical activity (PA) in AN. WP5 conducted a RCT (ISRCTN18274621) of an e-mail-guided relapse prevention programme for inpatients with AN. WP6 analysed cohort data to examine the effects of maternal EDs on fertility and their children’s diet and growth. WP7a examined clinical case notes to explore how access to specialist ED services affects care pathways and user experiences. Finally, WP7b used data from this programme and the British Cohort Study (1970) to identify the costs of services used by people with AN and to estimate annual costs of AN for England.ResultsWP1a: a brief training programme improved knowledge, attitudes and confidence of school staff in managing EDs in school. WP1b: a teacher-delivered intervention was feasible and improved risk factors for EDs in adolescent girls. WP2a: both psychological therapies improved outcomes in outpatients with AN similarly, but patients preferred one of the treatments. WP2b: the inpatient treatment (Cognitive Remediation and Emotional Skills Training) was acceptable with perceived benefits by patients, but showed no benefits compared with treatment as usual (TAU). WP3: compared with TAU, the carer intervention improved a range of patient and carer outcomes, including carer burden and patient ED symptomatology. WP4: drive to exercise is tied to ED pathology and a desire to improve mood in AN patients. PA was not increased in these patients. WP5: compared with TAU, the e-mail-guided relapse prevention programme resulted in higher body mass index and lower distress in patients at 12 months after discharge. WP6: women with an ED had impaired fertility and their children had altered dietary and growth patterns compared with the children of women without an ED. WP7a: direct access to specialist ED services was associated with higher referral rates, lower admission rates, greater consistency of care and user satisfaction. WP7b: the annual costs of AN in England are estimated at between £45M and £230M for 2011.ConclusionsThis programme has produced evidence to inform future intervention development and has developed interventions that can be disseminated to improve outcomes for individuals with AN. Directions for future research include RCTs with longer-term outcomes and sufficient power to examine mediators and moderators of change.Trial registrationCurrent Controlled Trials ISRCTN42594993, ISRCTN67720902, ISRCTN06149665 and ISRCTN18274621.FundingThis project was funded by the National Institute for Health Research (NIHR) Programme Grants for Applied Research programme and will be published in full inProgramme Grants for Applied Research; Vol. 5, No. 16.

“…AN most commonly occurs during adolescence, with research suggesting that late adolescence, between the ages of fifteen and nineteen years, accounts for approximately 40% of all cases [2][3][4]. In adolescence it is important to consider the added complexities due to this being a developmentally sensitive time in which poor nutrition, hormonal changes and high levels of stress disrupt brain maturation [5].…”

How do we get our Daughter back? Parents' Perspectives on Recovery from Anorexia Nervosa

Background: Anorexia Nervosa is a severe mental illness most commonly occurring during adolescence. As a parent, caring for a child with Anorexia Nervosa can quickly consume all aspects of family life, leading to frustration, feelings of burden and increased levels of anxiety and depression. Despite the impact of the illness on parents, there is a surprising lack of literature drawing on parents perspectives of recovery, particularly during adolescence.
