- Aim: The use of serum insulin-like growth factor-1 (IGF-1) concentrations as an index of nutrition has been analysed in teenage girls with eating disorders and weight loss. Method: Blood samples for analysis of IGF-1 were obtained at 349 assessments of 302 patients and biweekly during 56 treatment periods in 46 patients. IGF-1 was related to body size, weight loss, degree of leanness (BMI standard deviation score) and rate of weight loss. Results: At assessment, when most of the girls were on a weight-losing course, serum IGF-1 concentrations were low. Weight loss immediately prior to assessment was the most important predictor of IGF-1. Together with measurements of weight, height, weight loss and BMI standard deviation score the rate of weight loss predicted IGF-1 to 32–55%. During treatment when there was net weight gain, IGF-1 increased in parallel with the BMI standard deviation score, a measure of leanness, and was also influenced by the short-term weight trend. Conclusion: The serum IGF-1 concentration is an indicator of nutritional status in adolescents with eating disorders. It is sensitive to short-term weight changes measured in a clinical setting and could be used at assessment and to monitor nutritional rehabilitation.

- Aim: Circulating thyroid hormone concentrations are influenced by nonthyroidal disease and changes in nutritional status. We studied thyroid hormones as possible indicators of nutrition in adolescent girls with eating disorders. Method: Blood samples for analyses of thyroid hormones were obtained at 360 assessments of 298 patients and biweekly during 42 treatment periods in 36 patients. Results: At assessment, when most of the girls were on a weight losing course, serum triiodothyronine (T3) concentrations were low. Great weight loss and rapid rate of weight loss were the most important predictors of low T3 concentrations. Serum free thyroxine concentrations were in the lower normal range. In premenarcheal girls, weight loss was the most important predictor of free thyroxine but this relationship was weaker in postmenarcheal girls. Serum TSH concentrations were within the normal range and only weakly related to weight changes. During treatment, T3 increased in parallel with weight but was also influenced by the short-term weight trend. Conclusion: Serum T3 concentration is an indicator of nutritional status in adolescent girls with eating disorders. It is sensitive to short-term weight changes and could be used to monitor progress throughout nutritional rehabilitation.

Adolescent Eating Disorders in a Sociocultural Context
- 2005
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Adolescence means an increased risk for eating disorders (ED) and the female gender is the most important risk factor. Empirical studies of the perceptions of gender ideals—as potential mediating factors between the socio-cultural context and ED—were this thesis’ primary goals. Further aims implied evaluating the psychometric properties of the Eating Disorders Inventory for Children (EDI-C) and providing normative data for boys and girls concerning self-assessed ED symptoms and related psychological traits.The EDI-C has satisfying psychometric properties, and normative data are now provided. The vast majority of preadolescent and adolescent boys and girls (n=4725) are not preoccupied with weight concerns, but 1–3% of the boys and 9–20% of the girls here indicate feelings of anxiety and problematic attitudes. An increase of self-reported ED symptoms occurs during female preadolescence and early adolescence. Responses to three open-ended questions—addressing perceived and personal gender ideals of adolescent boys (n=347) and girls with (n=204) and without (n=417) an ED—indicate that girls are, compared to boys, more involved in images of ideals. The perceived ideal man and ideal woman differ in body size and strength. This corresponds with different health risk behaviours reported in boys (body building) and girls (dieting). Awareness of media ideals and an ability to discriminate them from individual values was common in the normal groups and in girls who had recovered from an ED. A poor outcome was associated with thinness stated as ideals of the media, without mentioning good looks. Factors that could predict outcome at the 3-year follow-up of an ED in adolescent girls were: good looks (media ideal), maturity fears, profession (individual ideal), sexual debut, and vomiting.The addition of a gender perspective would add a dimension to programmes aiming at preventing and treating ED in adolescence.

- ObjectiveTo evaluate the Swedish version of the Eating Disorder Inventory for Children (EDI-C) from a gender and developmental perspective and to provide normative data.MethodsData were collected within seven cross-sectional projects. Completed questionnaires, from 2070 boys and 2655 girls in grades 4–12, were included.ResultsThe psychometric properties of EDI-C in non-clinical groups of girls and adolescent boys resemble those found for adolescent girls with an eating disorder. Significant differences were found between genders, grades and pre-adolescent and adolescent groups. An increase in drive for thinness, body dissatisfaction and problems with interoceptive awareness and impulse regulation characterized the adolescent girls. Maturity fears, interpersonal distrust and social insecurity decreased during adolescence for both genders.ConclusionsThe results indicate that the EDI-C could well be used for both boys and girls, although separate norms are recommended for pre-adolescents and adolescents as well as for boys and girls.

- Three open-ended questions based on Steiner-Adair (1986) were used to study gender concepts in relation to ideals in adolescent boys and girls and eating-disordered girls. The answers were coded according to themes emanating from the collected data and not predetermined. Dichotomous differences were found between the genders regarding perceived ideals of body size, but clinical and nonclinical girls perceived ideals of society and media similarly. Individual gender concepts differed substantially from the perceived ideals, and were most often focused on lifestyle and life conditions. However, the clinical girls were somewhat more likely to emphasize appearance and loving relationships.
