Prevalence and clinical determinants of low bone mineral density in anorexia nervosa.

OBJECTIVE: To determine the prevalence of low bone mass in anorexia nervosa (AN) and the association with clinical parameters. METHODS: A cross-sectional study on 286 Caucasian women with AN. Bone mineral density (BMD) was measured with DXA. Low BMD was defined as a Z-score

A community study of psychosocial functioning and weight in young children and adolescents.

BACKGROUND: Children with either underweight or overweight may be at risk for mental health problems and require mental health service use. The present study investigated the relationship between weight status and psychosocial dysfunctioning in children of two different age groups (5-6 and 13-14 years). METHODS: Using height and weight measurements collected during routine medical examinations of all children in a circumscribed geographical region, measures of underweight and overweight were calculated in young children (aged 5-6 years; n=797) and in adolescents (13-14 years; n=614). In addition, parent-reported questionnaires (young children) and adolescent-reported questionnaires (adolescents), including the Strengths and Difficulties Questionnaire (SDQ), provided information on psychopathology subscales including emotional symptoms, conduct problems, hyperactivity-inattention, peer problems and prosocial behaviour. RESULTS: Few associations were apparent after controlling for confounding variables. Young children who were underweight (but not severely underweight) less frequently displayed conduct problems, while adolescents who were overweight or obese reported more peer problems and less prosocial behaviour than did children of normal weight. Children who were underweight and children who were overweight did not score higher on any of the other psychopathology scales than did children of normal weight in either age group. CONCLUSION: Our findings suggest that the domains of weight problems and psychopathology do not display strong associations. However, there are indications that some areas of psychopathology may be differentially associated with weight problems. Further longitudinal research is warranted.

Personality and vulnerability to depression in stroke patients: a 1-year prospective follow-up study.

BACKGROUND AND PURPOSE: Depression is a frequent sequela of stroke that negatively interferes with rehabilitation outcome. Personality traits have been neglected as potential vulnerability factors for poststroke depression (PSD). In a 1-year prospective study, the influence of the 5 main personality traits (ie, neuroticism, extraversion, openness, agreeableness, and conscientiousness) on the development of PSD was studied. METHODS: One month after stroke, 190 consecutive patients with a first-ever supratentorial infarct were asked to complete a personality inventory, the NEO-Five Factor Inventory, which is based on the Five Factor Model of personality. Depressive symptoms were assessed 1, 3, 6, 9, and 12 months after stroke with 3 self-rating questionnaires as screening instruments for depression. PSD was diagnosed as major or minor depression through the use of the Structured Clinical Interview from the Diagnostic and Statistical Manual of Mental Disorders. RESULTS: The 1-year cumulative incidence of depression was 38.7%. Cox regression analysis showed that patients with high neuroticism scores had a 4.6-times-higher risk of developing PSD than patients with low neuroticism scores (P=0.001) regardless of lesion location. Level of handicap was the only other factor that showed an independent effect on the occurrence of PSD. CONCLUSIONS: Neuroticism is an important predictor of PSD, a finding that emphasizes the need to take personality into account as a potential vulnerability factor for depression in stroke patients. Research on PSD should aim at delineating the interplay between neurological and psychological factors in the development of PSD.
