Sleep problems and fatigue in chronically ill women

Sleep parameters measured by accelerometry: descriptive analyses from the 22-year follow-up of the Pelotas 1993 birth cohort

OBJECTIVE

To describe the sleep time window (STW), total sleep time (TST), and sleep percent [SP = (TST/STW) × 100] by accelerometry in a population-based young adult cohort in Brazil.

METHODS

Cross-sectional analysis with a 22-year sample (N = 2462). Sleep variables were measured using an accelerometer. The devices were worn on the non-dominant wrist for approximately seven days. A raw data analysis using the GGIR package was performed. The following sleep variables were extracted: TST, STW, and SP. Linear regression was used to adjust averages. All analyses were stratified according to sex. A comparison between weekday and weekend averages was also conducted.

RESULTS

The means of TST, STW, and SP for men were 5.9 h, 7.1 h, and 83.1%, respectively. For women, the means of TST, STW, and SP were 6.4 h, 7.6 h, and 84.6%, respectively. Women presented a higher means of all outcomes compared to men (p < 0.001). After adjusting for both sexes, white skin color and not working or studying were associated with higher TST. Individuals not working or studying presented higher means of STW and lower sleep SP. Women with children who were less than two years of age presented lower values of three evaluated outcomes. Regarding behavior and health condition variables, obesity was associated with lower STW only for men. Physical activity was associated with higher SP and risk drinking with lower TST and STW only for women.

CONCLUSION

Differences between sexes were observed in TST, STW, and SP. In all outcomes women presented a higher means. Socioeconomic variables were associated with both sexes, but having children and behavior/health conditions differed between sexes.

Assessment of Sleep Quality and Effects of Relaxation Exercise on Sleep Quality in Patients Hospitalized in Internal Medicine Services in a University Hospital: The Effect of Relaxation Exercises in Patients Hospitalized

This study aims to assess sleep quality and determine the effects of relaxation exercise on sleep quality in patients hospitalized in internal medicine services. In total, 47 patients comprised the control group and did not engage in the exercise intervention--the progressive muscle relaxation exercise, whereas 235 patients were assigned to the intervention group (N = 282). In this study, Description Questionnaire Form and the Pittsburg Sleep Quality Index (PSQI) were used. Most patients (73.8%) had poor sleep quality. The mean pre- and postexercise PSQI scores of the patients in the interventional group were 8.7 ± 4.0 and 6.1 ± 3.3, respectively. The mean pre- and postexercise PSQI scores of the control patients were 6.6 ± 3.5 and 5.6 ± 2.7, respectively. According to this study, the exercises significantly enhanced the quality of sleep. Patients should be encouraged by nurses to perform relaxation exercises.
