Association between psycho-psychological factors and functional dyspepsia in elderly patients: Effect on activity of daily living score

Mediating and regulating effects of sleep quality on anxiety and ability of daily living in elderly patients with functional dyspepsia

BACKGROUND

Functional dyspepsia (FD) is a common disease that affects the health and quality of life of elderly patients. Sleep quality, ability to live daily, and emotional state are the main contributing factors. This study investigated the role of improving sleep quality in regulating negative emotions and improving daily living ability of elderly FD patients.

AIM

To investigate the mediating and regulating effects of sleep quality on anxiety and daily living ability in elderly patients with FD.

METHODS

Elderly FD patients admitted to our hospital from August 2018 to December 2019 were selected by convenience sampling method. Pittsburgh sleep quality scale, anxiety scale, and daily living ability scale were used for investigation and analysis. Pearson correlation analysis and multiple hierarchical regression analysis were used to analyze the survey results.

RESULTS

The scores of anxiety scale and daily living ability scale, and total score of sleep quality were 38.94 ± 9.58, 18.74 ± 7.69, and 8.73 ± 2.64, respectively. The scores of sleep continuity, subjective sleep, sleep drug use, sleep latency, habitual sleep efficiency, sleep disorder, and daytime dysfunction were 0.75 ± 0.24, 1.21 ± 0.53, 0.26 ± 0.13, 1.46 ± 0.35, 0.67 ± 0.18, and 1.43 ± 0.52, respectively. In elderly FD patients, anxiety was negatively correlated with daily living ability (r = -0.348, P < 0.05), and positively correlated with sleep quality (r = 0.553, P < 0.05), while daily living ability was positively correlated with sleep quality (r = 0.354, P < 0.05). The mediating effect equation was used to analyze the mediating effect of sleep on daily living ability and anxiety in elderly FD patients. The mediating effect was 0.131, accounting for 37.25% of the total effect. Stratified regression analysis showed that anxiety had a predictive effect on daily living ability, and sleep quality had a regulatory effect on anxiety and daily living ability in elderly FD patients.

CONCLUSION

Sleep has mediating and regulating effects on anxiety and daily living ability in elderly patients with FD. In clinical work, medical staff can improve daily living ability and relieve anxiety by regulating the sleep quality of patients.
