Key result
Poor sleep quality was not associated with statistically significant differences in cardiac autonomic control compared to good sleep quality among functionally active older adults.
Why the study?
The study was conducted to identify differences in cardiac autonomic control between older people with good and poor sleep quality.
Does poor sleep quality reduce cardiac autonomic control (measured by HRV) in functionally active older adults?
Cross-Sectional (n=31)
No
Does poor sleep quality reduce cardiac autonomic control (measured by HRV) in functionally active older adults?
p-value: p=>0.05
In functionally active older adults without known cardiovascular disease, poor sleep quality was not associated with significant differences in resting cardiac autonomic control as measured by short-term heart rate variability.
No HRV differences by sleep quality observed in older adults; leaves open whether larger longitudinal studies would detect associations.
Objective To identify the differences in cardiac autonomic control between older people with good and poor sleep quality. Material and Methods This is a cross-sectional study with 40 older people aged ≥ 60 years, registered at a community health center in Petrolina, Pernambuco, Brazil. The sleep quality was assessed with the Pittsburgh Sleep Quality Index (PSQI). To assess heart rate variability (HRV), the RR intervals (RRI) were recorded for 10 min with a validated smartphone app and a wireless transmitter Polar H7 positioned on the patient’s chest. The HRV parameters were calculated with Kubios HRV, and the data were analyzed in SPSS. Subjects with good and poor sleep quality (PSQI >5) were compared with the Mann-Whitney U test. Results A total of 31 older people were included in the final analysis, with 18 (58.1%) of them having poor sleep quality. Older people with good sleep quality have similar cardiac autonomic control to those with poor sleep quality. The medians of time (mean RRI, pNN50, SDNN, and RMSSD) and frequency-domain HRV parameters (LFms2, LFnu, HFms2, HFnu, and LF/HF ratio) were statistically similar (p > .05) in older people with good and poor sleep quality. According to the effect size, the HRV indicators were slightly better among those with good sleep quality. Conclusion There were no statistical differences in cardiac autonomic control between older people with good and poor sleep quality.

Rocha et al. (2023) conducted a cross-sectional in Poor sleep quality (n=31). Poor sleep quality vs. Good sleep quality was evaluated on Cardiac autonomic control (HRV parameters) (p=>0.05). Poor sleep quality was not associated with statistically significant differences in cardiac autonomic control compared to good sleep quality among functionally active older adults.
