| Abstract |
We investigated the prevalence of suicidal ideation in relationship with symptoms of sleep disruption in people with postural orthostatic tachycardia syndrome (POTS). Online surveys (including the Pittsburgh Sleep Quality Index and the Suicide Behaviors Questionnaire - Revised) were completed by 705 POTS patients and 170 non-POTS controls. Poor sleep quality was reported in 98.4% of POTS patients with a calculated subjective sleep efficiency of 65.4%. The POTS group's sleep efficiency was significantly lower (t[873]= -11.32; p<0.001) and sleep disturbances because of pain were significantly higher (t[873]=15.36; p<0.001) than controls. Chi-square testing showed a larger proportion of individuals at high-risk for suicide among POTS patients than controls (c(2) [1, n=875]=55.6; p<0.001). Multiple linear regression analysis showed that sleep scores (β=0.23, p<0.001), age (β=-0.03, p<0.001), and illness with POTS (β=0.68, p=0.05) were significantly associated with suicide ideation scores (F[4, 870]=38.34, p<0.001). This model explained 15% of variance (R(2)=0.15) in suicidal ideation scores. Patients with POTS may suffer from increased sleep disturbance and suicidal ideation compared with the general population. Treatment to improve sleep efficiency and sleep quality is an important step toward better quality of life for POTS patients. |

Attention Score in Context
This research output has an Altmetric Attention Score of 6. 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 22 March 2023.
All research outputs
#6,564,179
of 25,593,129 outputs
Outputs from Nature and science of sleep
#236
of 634 outputs
Outputs of similar age
#96,948
of 324,467 outputs
Outputs of similar age from Nature and science of sleep
#9
of 11 outputs
Altmetric has tracked 25,593,129 research outputs across all sources so far. This one has received more attention than most of these and is in the 74th percentile.
So far Altmetric has tracked 634 research outputs from this source. They typically receive a lot more attention than average, with a mean Attention Score of 26.5. This one has gotten more attention than average, scoring higher than 62% 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 324,467 tracked outputs that were published within six weeks on either side of this one in any source. This one has gotten more attention than average, scoring higher than 69% of its contemporaries.
We're also able to compare this research output to 11 others from the same source and published within six weeks on either side of this one. This one is in the 18th percentile – i.e., 18% of its contemporaries scored the same or lower than it.
