Sleep quality and associated factors among patients with chronic kidney disease in Nigeria: a cross-sectional study

OBJECTIVE

Poor sleep quality adversely affects the overall well-being and outcomes of patients with chronic kidney disease (CKD). However, it has not been well studied in Africans with CKD. We determined the prevalence of poor sleep quality and associated factors among patients with CKD.

DESIGN

This was a cross-sectional study that involved patients with CKD .

SETTINGS

The study was carried out in the outpatient clinic of nine hospitals in Nigeria.

METHODS

Sleep quality, depressive and anxiety symptoms and quality of life (QoL) were assessed among 307 patients with CKD using Pittsburgh Sleep Quality Index Questionnaire, Hospital Anxiety Depression Scale Questionnaire and 12-item Short Form Health Survey Quality of Life Questionnaire, respectively. The prevalence of poor sleep quality and associated factors were determined. A p<0.05 was considered as statistically significant.

RESULTS

The mean age of the study participants was 51.40±15.17 years. The male:female ratio was 1.5:1 One hundred and twenty-one (39.4%) of the patients were on maintenance haemodialysis (MHD). The prevalence of poor sleep quality, anxiety symptoms and depressive symptoms among the patients was 50.2%, 37.8% and 17.6%, respectively. The prevalence of poor sleep quality in the CKD stages 3, 4, 5 and 5D was 38.1%, 42.6%, 52.2% and 58.7%, respectively. The prevalence of poor sleep quality was significantly higher in MHD patients compared with predialysis CKD (59.5% vs 43.6%; p=0.008). Factors associated with poor sleep quality were CKD stage (p=0.035), anaemia (p=0.003), pruritus (p=0.045), anxiety symptoms (p≤0.001), depressive symptoms (p≤0.001) and reduced QoL (p≤0.001). On multivariate analysis, factors associated with poor sleep were anxiety (AOR 2.19; 95% CI 1.27 to 3.79; p=0.005), anaemia (AOR 5.49; 95% CI 1.43 to 21.00;p=0.013) and reduced physical component of QoL (AOR 4.11; 95% CI 1.61 to 10.47; p=0.003).

CONCLUSION

Poor sleep quality is common among patients with CKD especially in the advanced stage. The significant factors associated with poor sleep quality were QoL, anaemia and anxiety symptoms. These factors should be adequately managed to improve the overall outcomes of patients with CKD.

Determinants of Interest in Nephrology Career Choice among Internal Medicine Junior Residents in Nigeria

INTRODUCTION

There has been decreased interest in postgraduate nephrology training over the years. This trend could worsen the shortage of nephrologists and inability to meet the health needs of patients with kidney diseases if not urgently addressed.

AIM

To determine interest in and determinants of nephrology career choice among junior internal medicine residents in Nigeria.

METHODOLOGY

This was a cross-sectional study that enrolled 273 junior residents in internal medicine across Nigeria. A self-administered questionnaire that was adapted from two previous studies was used for data collection.

RESULTS

The mean age of the respondents was 33.6±4.4 years with a male: female ratio of 1.8:1. This study showed that 16.8% and 21.6% of junior residents in internal medicine considered nephrology as their first and second choice area to specialize, respectively. Factors that ranked high as determinants of a decision to do nephrology were personal interest (94.3%), opportunities to perform renal procedures (93.3%), and exposure to nephrology training (85.7%). Factors that discouraged a choice of nephrology according to respondents were high mortality of renal patients (67.3%), poor outcomes of renal patients (70.2%), in ability to fund treatment by renal patients (66.1%), unsatisfactory life-work balance among nephrologists (60.7%), and late presentation of renal patients (59.0%). Others were high workload compared to available doctors (59.0%) and poor job satisfaction (55.4%). Factors that could stimulate more interest in nephrology according to respondents included creation of better working environment with adequate equipment for training (96.3%), provision of health insurance with adequate coverage for renal patients (97.4%), and increased government support for renal care services (99.3%).

CONCLUSION

There is a need to promote and sustain interest of residents in nephrology by ensuring improved survival of patients through better access to renal care, ensuring an adequate and well motivated work force, provision of adequate facilities and health insurance services.

Hypertension and Diabetes Self-care Activities: A Hospital Based Pilot Survey in Benin City, Nigeria

AIMS AND OBJECTIVES

The burden of hypertension and diabetes is on the increase globally with its attendant complications. Although self-care activities are critical to the successful management of both conditions, there are only a few reports on such activities, especially in this part of the world. This pilot study was therefore undertaken to assess the self-care activities among hypertensive and diabetic patients in Benin City.

PATIENTS AND METHODS

Hypertensive and diabetic patients were consecutively recruited from the out- patient department of the University of Benin Teaching Hospital. The questionnaires were developed based on past assessment scales such as the Hypertension Self-Care Activity Level Effects (H-SCALE) and the Summary of Diabetes Self-Care Assessment (SDSCA) for hypertensive and diabetic participants respectively.

RESULTS

A total of 85(32 hypertensive, 24 diabetic and 29 co-morbid hypertensive diabetic) participants completed the study. Only 14 (16.5%) subjects had good self-care practice, 39 (45.9%) had fair practice while poor self-care practice was found in 32 (37.6%) subjects. Adherence to medications, clinic adherence, use of self-monitoring devices, regular exercising and dietician contact were generally low. However, only a relatively few subjects smoked tobacco or took significant alcohol.

CONCLUSION

The health-related self-care practice among the patients was generally not good. There was no significant difference in the overall level of self-care among hypertensive, diabetic patients or those with co-morbid conditions. There is need for more aggressive health education aimed at improving the current health-related self-care habits among these patients.

Prevalence and correlates of chronic kidney disease among civil servants in Bayelsa state, Nigeria

INTRODUCTION

Chronic kidney disease (CKD) has become a public health problem with rising incidence and prevalence world-wide. Despite the fact that Sub-Saharan Africa, including Nigeria appears to be badly hit by this epidemic, there is a paucity of data on CKD prevalence in these regions and where data exists, they are mostly hospital-based.

OBJECTIVES

The present study was carried out to determine the prevalence and correlates of CKD in an urban civil service population in Bayelsa State, Nigeria.

MATERIALS AND METHODS

A total of 179 civil servants in the Bayelsa State secretariat were screened for CKD during the World Kidney Day on March 2012. CKD was defined as estimated glomerular filtration rate <60 ml/min/1.73 m 2 body surface area and/or proteinuria. Socio-demographic data was obtained using interviewer-administered semi-structured questionnaire while anthropometric measurements were taken. Blood pressure (BP), urinalysis, serum urea and creatinine were also assessed.

RESULTS

The prevalence of CKD in the study was 7.8%. Age >50 years was associated with CKD in univariate analysis but none of age, gender, body mass index, BP or hyperglycemia independently predicted it.

CONCLUSION

The prevalence of CKD among Nigerian civil servants was fairly high and was associated with advancing age. Routine screening for CKD in this population is recommended.

Choice of medical specialties amongst final year medical students in two universities in South-South, Nigeria

Study aimed at determining the preferred medical specialties among final year medical students and the most important factor(s) influencing their choices.

METHODS

A cross-sectional questionnaire-based survey was carried out among all final year medical students from the University of Benin (UNIBEN) and the Niger Delta University (NDU). The study was done in UNIBEN in July 2011 and subsequently in NDU in March 2012.Students were asked to choose the most preferred specialty out of a list of options and to select the most important factors influencing their choice.

RESULTS

A total of one hundred and sixty seven (102 UNIBEN and 65 NDU) students completed the study. A hundred (59.9%) respondents preferred surgery-related specialties while forty nine (29.3%) preferred medicine-related specialty. Forty five (26.9%) students preferred surgery while thirty six (21.6%) preferred obstetrics and gynaecology. Internal medicine and paediatrics were preferred amongst 18(10.8%) and 10(6.0%) respondents respectively. Other specialties were chosen to a lesser degree. Personal interest in 95(56.9%) participants was the most important factor influencing choice of medical specialties.

CONCLUSION

The study highlights a general preference for core clinical specialties and surgery-related specialties especially surgery and obstetrics and gynaecology, amongst final year medical students. Personal interest was the most important factor influencing career choice. These findings have important implications for Nigeria's medical education and health care policy making.
