Is insomnia associated with self-reported health and life satisfaction in cardiac arrest survivors? A cross-sectional survey.

Background: Insomnia symptoms seem to be common in cardiac arrest survivors but their associations with important outcomes such as self-reported health and life satisfaction have not previously been reported during the early post-event period. Therefore, the aim of the study was to investigate whether symptoms of insomnia are associated with self-reported health and life satisfaction in cardiac arrest survivors six months after the event. Methods: This multicentre cross-sectional survey included cardiac arrest survivors ≥18 years. Participants were recruited six months after the event from five hospitals in southern Sweden, and completed a questionnaire including the Minimal Insomnia Symptom Scale, EQ-5D-5L, Health Index, Hospital Anxiety and Depression Scale, and Satisfaction With Life Scale. Data were analysed using the Mann-Whitney U test, linear regression, and ordinal logistic regression. The regression analyses were adjusted for demographic and medical factors. Results: In total, 212 survivors, 76.4% males, with a mean age of 66.6 years (SD = 11.9) were included, and of those, 20% reported clinical insomnia. Insomnia was significantly associated with all aspects of self-reported health (p < 0.01) and life satisfaction (p < 0.001), except mobility (p = 0.093), self-care (p = 0.676), and usual activities (p = 0.073). Conclusion: Insomnia plays a potentially important role for both health and life satisfaction in cardiac arrest survivors. Screening for sleep problems should be part of post cardiac arrest care and follow-up to identify those in need of further medical examination and treatment.

A comprehensive description of self-reported health and life satisfaction in cardiac arrest survivors.

BACKGROUND: Self-reported health and life satisfaction are considered important outcomes in people surviving cardiac arrest. However, most previous studies have reported limited aspects on health, often based on composite scores, and few studies have focused on life satisfaction. Investigating health aspects with a broad and detailed perspective is important to increase the knowledge of life after cardiac arrest from the perspective of survivors. In addition, the knowledge of potential differences in health among survivors related to place of arrest (in-hospital cardiac arrest; IHCA or out-of-hospital cardiac arrest; OHCA) is scarce. The aim was to describe and compare self-reported health and life satisfaction in IHCA and OHCA survivors.  METHODS: This observational cross-sectional study included adult cardiac arrest survivors six months after resuscitation, treated at five Swedish hospitals between 2013 and 2018. Participants received a study specific questionnaire including Health Index (HI), EQ-5D 5 Levels (EQ-5D-5L), Minimal Insomnia Sleeping Scale (MISS), Multidimensional Scale of Perceived Social Support (MSPSS), Hospital Anxiety and Depression Scale (HADS), and Satisfaction With Life Scale (SWLS). In order to present characteristics descriptive statistics were applied. The Mann-Whitney U test, chi-square test or Fishers' exact test were used to compare differences in self-reported health and life satisfaction between in-hospital- and out-of-hospital cardiac arrest survivors RESULTS: In total, 212 survivors participated. Based on scale scores and general measures, the median scores of health and life satisfaction among survivors were high: HI total = 29, EQ VAS = 80, and SWLS = 20. According to HI, most problems were reported for tiredness (37.3 %) and strength (26.4 %), while pain/discomfort (57.5 %) and anxiety/depression (42.5 %) where most common according to EQ-5D-5L. Except for EQ-5D-5L mobility (p = 0.023), MSPSS significant other (p = 0.036), and MSPSS family (p = 0.043), no health differences in relation to place of arrest were identified. CONCLUSIONS: Although general health and life satisfaction were good among cardiac arrest survivors, several prevalent health problems were reported regardless of place of arrest. To achieve an improved understanding of health in cardiac arrest survivors, it is important to assess specific symptoms as a complement to composite scores of general, physical, emotional, and social health.

Association between Sleep Disturbances and Leisure Activities in the Elderly: A Comparison between Men and Women.

It has been suggested that physical or social activity is associated with fewer sleep disturbances among elderly people. Women report more sleep disturbances than men, which could indicate a variation in activity patterns between the genders. The aim of this study was to investigate associations between sleep disturbances and leisure activities in men and women (n = 945) aged ≥60 years in a Swedish population. Sleep disturbances were measured using eight dichotomous questions and seventeen variables, covering a wide range of leisure activities. Few leisure activities were found to be associated with sleep disturbances and their importance decreased when the models were adjusted for confounders and gender interactions. After clustering the leisure activities and investigating individual activities, sociointellectual activities were shown to be significant for sleep. However, following adjustment for confounders and gender interactions, home maintenance was the only activity significant for sleep. Being a female increased the effect of home maintenance. Besides those leisure activities, poor/fair self-rated health (OR 7.50, CI: 4.27-11.81) and being female (OR 4.86, CI: 2.75-8.61) were found to have the highest association with poor sleep. Leisure activities pursued by elderly people should focus on activities of a sociointellectual nature, especially among women, to promote sleep.
