Macronutrient intake associated with weight gain in adolescent girls with anorexia nervosa

Abstract ObjectiveAdolescents and women with anorexia nervosa (AN) are known to severely restrict total calorie and fat intake. However, data are limited regarding specific macronutrient intake associated with weight gain in AN. ObjectiveTo prospectively investigate dietary macronutrient composition associated with weight gain in adolescent girls with AN. MethodA prospective naturalistic study of 90 girls 12–18 years old; 45 with AN and 45 healthy normal‐weight‐controls over a 6–12‐month period. Participants completed four‐day food diaries and underwent body composition assessment using dual energy x‐ray absorptiometry. Weight gain was defined as a ≥10% increase in BMI from baseline. ResultsBaseline clinical characteristics did not differ between girls with AN who did not gain weight (AN‐0) versus those who did (AN‐1) over the following 6–12 month period except for percentage of calories from proteins (p = 0.046). At 6–12 month follow up, AN‐1 consumed a lower percentage of total calories from protein (p = .001), and a higher percentage of total calories from fat (p = .02) compared to AN‐0. AN‐1 had a significant increase in the percentage of total calories obtained from and poly‐unsaturated‐fatty acids (PUFA) (p = 0.006) compared to AN‐0, between baseline and follow up. Within the AN group, BMI at follow‐up was associated positively with percentage of total calories...

Abstract Subchondral insufficiency fracture (SIF) is a fragility fracture secondary to osteoporosis that leads to collapse of the femoral head with no evidence of osteonecrosis. SIF of the femoral head has been reported in adults of varying ages and both sexes, but it has never been reported to occur in pregnant women. Herein, we describe a 40-year-old primiparous patient with pre-existing anorexia nervosa who developed SIF of the femoral head in the third trimester. At 29 weeks of gestation, the patient complained of sudden pain on walking in both hips. Despite the bed rest, her hip pain increased; consequently, ...

ABSTRACTBackgroundBone health and growth during adolescence require adequate total body protein (TBPr). Renutrition for patients with anorexia nervosa (AN) should aim to normalize body composition and to recover both fat mass and TBPr.ObjectiveWe intended to analyze predictors of protein status, including exercise status, in adolescents with AN and to investigate whether weight gain would replenish body protein deficits.MethodsWe assessed TBPr in a longitudinal, observational study as height-adjusted nitrogen index (NI) using in vivo neutron activation analysis in 103 adolescents with AN [mean ± SD age, 15.6 &p...

CONCLUSIONS: The current study did not demonstrate a vitamin D deficiency in patients with AN and our data does not support vitamin D deficiency as a contributing factor to bone loss in AN. Instead, we observed a trend toward higher vitamin D levels in AN subjects compared to controls. Measurement of free vitamin D levels did not contribute to additional information.

ABSTRACT ObjectiveDSM‐5 revised the diagnostic criteria for anorexia nervosa (AN) by eliminating the amenorrhea requirement, liberalizing weight and psychological criteria, and adding the formal diagnosis of “atypical AN” for individuals with AN psychological symptoms without low weight. We sought to determine whether bone density (BMD) is impaired in women diagnosed with AN using the new, more liberal, DSM‐5 criteria. MethodCross‐sectional study of 168 women, 18 − 45y: (1) AN by DSM‐IV (DSM‐IV AN) (n = 37), (2) AN by DSM‐5 but not DSM‐IV criteria (DSM‐5 AN) (n&...

DiscussionFat percentage and body mass index were positive predictors of the resumption of menses, however, body composition measured by dual energy X‐ray absorptiometry was not superior to body mass index in predicting menstrual recovery, which is of great clinical relevance as body mass index is easier and cheaper to obtain. Body composition measures only account for one of numerous factors involved in the resumption of menses. Regression models based on our data had a R2 value of 0.14, indicating that only 14% of the variation in menstrual recovery could be explained by the variables included. © 2016 Wiley Period...
