| Abstract |
The impact of stress on circulating levels of appetite-regulating hormones remains largely unknown. The aim of this study was to analyze the effect of acute psychosocial stress on the gut hormone peptide YY (PYY) secretion in obese and normal weight women. Therefore, we compared pre- and post-prandial plasma PYY secretion of 42 obese and 43 normal weight women in a repeated measure randomized controlled laboratory experiment. PYY and cortisol concentrations were measured and ratings of stress and satiety were also recorded in response to a psychological stressor (Trier Social Stress Test, TSST). PYY samples were collected in the fasting state both before participating in the TSST and before a control session. Participants had a standardized meal after the TSST and control session, respectively. PYY was measured both 30 and 60 min after the TSST and control session, respectively. Stress inhibited PYY secretion as well as food intake in all women, but did not influence subjective satiety perception. The present data indicate that despite of lower PYY levels the subjects' requirement to overeat was not increased. From an evolutionary perspective this finding is adaptive. After stress the organism is prepared for fight or flight reaction, whereas not primarily necessary functions are inhibited. Therefore, increased food intake during stress would be dysfunctional. |

Attention Score in Context
This research output has an Altmetric Attention Score of 12. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 24 November 2023.
All research outputs
#3,020,998
of 25,376,589 outputs
Outputs from Eating and Weight Disorders - Studies on Anorexia, Bulimia and Obesity
#136
of 1,125 outputs
Outputs of similar age
#40,629
of 294,625 outputs
Outputs of similar age from Eating and Weight Disorders - Studies on Anorexia, Bulimia and Obesity
#3
of 24 outputs
Altmetric has tracked 25,376,589 research outputs across all sources so far. Compared to these this one has done well and is in the 88th percentile: it's in the top 25% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 1,125 research outputs from this source. They typically receive more attention than average, with a mean Attention Score of 9.1. This one has done well, scoring higher than 88% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 294,625 tracked outputs that were published within six weeks on either side of this one in any source. This one has done well, scoring higher than 86% of its contemporaries.
We're also able to compare this research output to 24 others from the same source and published within six weeks on either side of this one. This one has done particularly well, scoring higher than 91% of its contemporaries.
