Nível de atividade física de pacientes em hemodiálise: um estudo de corte transversal

Physical Activity and Quality of Sleep Among Patient with Chronic Kidney Disease on Hemodialysis: A Cross-Sectional Study

Background

Chronic kidney disease (CKD) patients on hemodialysis face issues like poor quality of sleep and reduced physical activity, which can impair their quality of life. This study aimed to assess the physical activity and quality of sleep among CKD patients on hemodialysis.

Materials and Methods

This cross-sectional study was conducted at All India Institute of Medical Sciences (AIIMS), Jodhpur. Data from 66 participants selected consecutively using self-reported standardized tools, namely, Global Physical Activity Questionnaire (GPAQ) and Pittsburgh Sleep Quality Index (PSQI), were collected, along with sociodemographic variables. After receiving written informed consent, questionnaires were administered through face-to-face interviews.

Results

The majority of the individuals, 45 (68.2%), were found to be physically active with a mean score of 2280.8 metabolic equivalents (MET)-min/week. The average PSQI score was 9.24 ± 4, and 49 (74.2%) participants had a PSQI score as higher than 5, suggesting poor quality of sleep. Physical activity and quality of sleep were found to have a significant relationship (P = 0.03). Physical activity was found to have a significant relationship with age (P = 0.01), whereas quality of sleep was associated with smoking status (P = 0.04), alcohol consumption (P < 0.01), and body mass index (BMI; P = 0.03).

Conclusion

Contrary to many studies where CKD patients on hemodialysis were found to be physically inactive, the present study showed a substantial portion of them to be physically active. Poor quality of sleep was common; hence, interventions to promote sleep quality recommended.

Efficacy of Benson's Relaxation Technique on Anxiety and Depression among Patients Undergoing Hemodialysis: A Systematic Review

This study aimed to evaluate the efficacy of Benson's relaxation technique on anxiety and depression among patients undergoing hemodialysis. A systematic review of randomized controlled trials was conducted. Searching databases included EBSCO Host, PubMed, ProQuest, Science Direct, Sage Journals, Ovid, and Google Scholar from January 2000 to September 2020. Five randomized controlled trials were identified. Findings revealed a statistically significant decrease in anxiety score. Concerning depression; one RCT showed a statistically significant decrease and two RCTs revealed a non-significant difference in depression level. The overall quality of the RCTs was not high. Despite that the RCTs showed benefits of BRT in managing anxiety. However, this is not the same for depression. The lack of high-quality scientific evidence supporting its retinue use indicates that additional well designed randomized controlled trials in multiple countries are warranted to support the efficacy of Benson's relaxation technique on anxiety and depression among patients undergoing hemodialysis.

Prevalence and correlates of physical activity across kidney disease stages: an observational multicentre study

BACKGROUND

People with chronic kidney disease (CKD) report high levels of physical inactivity, a major modifiable risk factor for morbidity and mortality. Understanding the biological, psychosocial and demographic causes of physical activity behaviour is essential for the development and improvement of potential health interventions and promotional initiatives. This study investigated the prevalence of physical inactivity and determined individual correlates of this behaviour in a large sample of patients across the spectrum of kidney disease.

METHODS

A total of 5656 people across all stages of CKD (1-2, 3, 4-5, haemodialysis, peritoneal dialysis and renal transplant recipients) were recruited from 17 sites in England from July 2012 to October 2018. Physical activity was evaluated using the General Practice Physical Activity Questionnaire. Self-reported cardiorespiratory fitness, self-efficacy and stage of change were also assessed. Binominal generalized linear mutually adjusted models were conducted to explore the associations between physical activity and correlate variables. This cross-sectional observational multi-centre study was registered retrospectively as ISRCTN87066351 (October 2015).

RESULTS

The prevalence of physical activity (6-34%) was low and worsened with disease progression. Being older, female and having a greater number of comorbidities were associated with greater odds of being physically inactive. Higher haemoglobin, cardiorespiratory fitness and self-efficacy levels were associated with increased odds of being active. Neither ethnicity nor smoking history had any effect on physical activity.

CONCLUSIONS

Levels of physical inactivity are high across all stages of CKD. The identification of stage-specific correlates of physical activity may help to prioritize factors in target groups of kidney patients and improve the development and improvement of public health interventions.

Attitudes of hemodialysis patients, medical and nursing staff towards patients' physical activity

PURPOSE

Patients with end-stage renal disease (ESRD) seem to have a negative attitude towards physical activity, which is mainly favored by the lack of counseling provided by the medical and nursing staff. The aim of this study was to investigate the attitudes of both ESRD patients and medical staff on the participation and promotion of physical activity and identify the obstacles that discourage patients' involvement in intervention programs.

STUDY DESIGN

Subjective assessment questionnaires and the International Physical Activity Questionnaire were administrated to hemodialysis patients and medical staff, to investigate the association between patient's barriers to physical activity, the total intensity level of physical activity, and attitudes of both ESRD patients and medical staff on the participation and promotion of physical activity.

RESULTS

A total of 103 ESRD patients (61 men, 59.2%), 20 nephrologists (12 men, 60.0%), and 72 nurses (61 women, 84.7%) participated in the study. Most commonly reported patient's barriers were fatigue on dialysis (97.4%) and non-dialysis days (55.1%). Healthcare staff showed positive attitude towards renal rehabilitation exercise programs. However, most of physicians (85.0%) and nurses (83.3%) did not have previous experience with interventional exercise rehabilitation programs. Binary logistic regression revealed significant association between patients' inactivity, demographic data, and barriers towards physical activity, such as fatigue and pain in dialysis and non-dialysis days (p < 0.05), family's and physician's concern (p < 0.05), too many medical problems (p < 0.05), the fear of getting hurt (p = 0.01), and unwillingness for exercise (p < 0.05). Interestingly, healthcare staff's negative attitudes toward patient's physical activity seem to be strongly associated with patient's inactivity status.

CONCLUSION

Healthcare staff negative attitudes and multiple related barriers especially fatigue on dialysis and non-dialysis days, towards ESRD patient's physical activity, suppress desire for exercise and active patients' status, leading them to abstain from it.

Atividade física e a qualidade de vida de pacientes com doença renal crônica em hemodiálise

RESUMO O objetivo deste estudo foi avaliar o nível de atividade física (NAF) de pacientes com doença renal crônica (DRC) em hemodiálise (HD) e correlacionar estes níveis à qualidade de vida relacionada à saúde (QVRS). Trata-se de um estudo correlacional, transversal, e com abordagem quantitativa. Participaram da pesquisa 84 pacientes com diagnóstico de DRC. Utilizou-se o questionário internacional de atividade física para identificar o NAF e o questionário genérico de qualidade de vida (SF-36) para avaliar a QVRS. Foram realizadas análises estatísticas descritivas. Utilizou-se o teste Kolmogorov-Smirnov e verificou-se ausência de normalidade nos dados. O teste U de Mann Whitney foi utilizado para a comparação da QVRS entre grupos (ativos e insuficientemente ativos), bem como o coeficiente de correlação de Spearman para correlacionar o NAF e a QVRS. O nível de significância adotado foi de 5%. Na comparação de grupos, verificou-se que os pacientes ativos apresentaram melhor percepção de QVRS se comparados aos insuficientemente ativos. Ainda, a partir do coeficiente de correlação de Spearman, observou-se que o NAF está correlacionado com a QVRS, com estatísticas significantes em diversas dimensões do SF-36. Sendo assim, sugere-se que a prática regular de atividade física (AF) pode contribuir para uma melhor percepção de QVRS de pacientes em HD.
