Factors associated with the increase in resting energy expenditure during refeeding in malnourished anorexia nervosa patients

Abstract

In AN patients, the rise in REE observed during refeeding was independently linked to anxiety level, abdominal pain, physical activity, and cigarette smoking, and it contributed to resistance to weight gain.

Thyroid Hormones and Their Relation to Weight Status

“…Most of our findings were in agreement with previous studies in younger girls with obesity [6,7,8,9] and to previous smaller cross-sectional studies in adolescents with AN [1,2,3]. Conversely, we were able to demonstrate for the first time that TSH levels were significantly decreased in girls with AN and increased in girls with AN and weight gain in contrast to previous reports [1,2,3].…”

“…Conversely, we were able to demonstrate for the first time that TSH levels were significantly decreased in girls with AN and increased in girls with AN and weight gain in contrast to previous reports [1,2,3]. However, decreased TSH concentrations in girls with AN, which tended to increase with weight gain were observed in these studies, too.…”

“…In adolescents with AN, low fT3 and normal thyroid-stimulating hormone (TSH) concentrations have been reported [1,2,3], while other studies did not find a change in thyroid hormones [4, 5]. Furthermore, there are only very few longitudinal studies in girls with AN based mostly on small sample sizes and, most importantly, on short observation periods demonstrating controversial findings, too [1,2,3,4].…”

“…Furthermore, there are only very few longitudinal studies in girls with AN based mostly on small sample sizes and, most importantly, on short observation periods demonstrating controversial findings, too [1,2,3,4]. In agreement with other reports in obese children [6, 7]), we have demonstrated moderately elevated TSH, total T3, and free T3 (fT3) levels in obese prepubertal and early pubertal children in two previous studies [8, 9].…”

Die Bedeutung körperlicher Aktivität bei Anorexia nervosa: Dimensionen, Erfassung und Behandlungsstrategien aus Expertensicht

“…Diese betreffen unter anderem den Energiestoffwechsel. Studien zum totalen Energieverbrauch (total energy expenditure, TEE) von Patientinnen mit AN konnten zeigen, dass sich deren TEE trotz Untergewichts nicht von dem gesunder Probanden unterscheidet [Casper et al, 1991;Pirke et al, 1991;Van Wymelbeke et al, 2004]. Dieses Ergebnis wurde mit einer erhöhten körperlichen Aktivität der PatientInnen erklärt.…”
