ObjectivesExamining the associations between health and lifestyle factors recorded in the participants’ early teens and development of suicidal thoughts recorded 4 years later.DesignPopulation-based prospective cohort study.SettingsAll students in the two relevant year classes in Nord-Trøndelag County were invited, 80% attended both waves of data collection.Participants2399 secondary school students who participated in the Young-HUNT1 study in 1995–1997 (13–15 years old) were included in a follow-up study 4 years later (17–19 years old).Primary outcome measureSuicidal thoughts reported at age 17–19 years.Results408 (17%, 95% CI 15.5% to 18.5%) of the adolescents reported suicidal thoughts at follow-up, 158 (14.2%, CI 13.6% to 16.4%) boys and 250 (19.5%, CI 18.8% to 22.0%) girls. Baseline anxiety and depressive symptoms (adjusted OR (aOR) 1.9, CI 1.4 to 2.6), conduct problems (aOR 1.8, CI 1.3 to 2.6), overweight (aOR 1.9 CI 1.4 to 2.4), and muscular pain and tension (aOR 1.8, CI 1.4 to 2.4), were all associated with reporting suicidal thoughts at follow-up.ConclusionsOne in six young adults experienced suicidal thoughts, girls predominating. Suicidal thoughts were most strongly associated with symptoms of anxiety/depression, conduct problems, pain/tension and overweight reported when participants were 13–15 years old. Specific preventive efforts in these groups might be indicated. Future research should investigate whether similar associations are seen with suicide/suicidal attempts as endpoints.

ObjectiveCompulsive exercise is a well‐known feature in eating disorders. The Exercise and Eating Disorder (EED) self‐report questionnaire was developed to assess aspects of compulsive exercise not adequately captured by existing instruments. This study aimed to test psychometric properties and the factor structure of the EED among women with eating disorders and a control group.MethodThe study included 449 female participants, including 244 eating disorders patients and 205 healthy controls. The patient group consisted of 32.4% (n = 79) AN patients, 23.4% (n = 57) BN, 34.4% (n = 84) EDNOS and 9.8% (n = 24) with BED diagnosis.ResultsThe analyses confirmed adequate psychometric properties of the EED, with a four‐factor solution: (1) compulsive exercise, (2) positive and healthy exercise, (3) awareness of bodily signals, and (4) weight and shape exercise. The EED discriminated significantly (p < .001) between patients and controls on the global score, subscales, and individual items. Test‐retest reliability was satisfactory (r = 0.86). Convergent validity was demonstrated by high correlations between the EED and the Eating Disorder Examination Questionnaire (EDE‐Q; r = 0.79).DiscussionThe EED is the first clinically derived, self‐report questionnaire to assess compulsive exercise among ED patients. The EED offers assessment that has broader clinical utility than existing instruments because it identifies treatment targets and treatment priorities. © 2015 Wiley Periodicals, Inc.

Background: The aim of this study was to explore changes in the BMI-distribution over time among Norwegian adolescents.
