Correlation Between Skeletal Muscle Mass and Fat-Free Mass in Infants Born Very Preterm.

Assessing growth quality in preterm infants present challenges, particularly with the use of the standard fat-free mass measurement. We report here a moderate correlation between indirect skeletal muscle mass measurements using the D3-creatine dilution method and fat-free mass measured with air-displacement plethysmography. Skeletal muscle mass could serve as an indicator of growth quality.

Stress-induced eating in women with binge-eating disorder and obesity.

The purpose of the current study was to investigate stress-induced eating in women with binge-eating disorder (BED) and obesity. Three groups of women [obese with BED (n=9); obese non-BED (n=11); and normal weight (NW) non-BED (n=12)], rated their levels of hunger and psychological distress before and after completing the Trier Social Stress Test, followed by food anticipation and then consumption of their preferred snack food. We differentiated between the motivational and hedonic components of eating by measuring the amount of food participants poured into a serving bowl compared to the amount consumed.

Binge eating disorder and obesity: preliminary evidence for distinct cardiovascular and psychological phenotypes.

This study investigated cardiovascular functioning, mood, and eating-related psychological factors at rest and in response to mental stress in three groups of women: 1) Obese women with binge eating disorder (BED; n=9); 2) obese non-BED women (n=15); and 3) normal weight (NW) non-BED women (n=15). Compared to both obese and NW non-BED women, obese women with BED showed heightened overall blood pressure and reported greater depression symptoms, perceived stress, and eating-related psychopathology. Additionally, obese women with BED reported greater overall negative affect and state anxiety compared to obese non-BED women.
