Physical activity and metabolic health in chronic kidney disease: a cross-sectional study.

ABSTRACT:

Background

Patients with chronic kidney disease (CKD) are at high risk of progression to end stage renal disease and cardiovascular events. Physical activity may reduce these risks by improving metabolic health. We tested associations of physical activity with central components of metabolic health among people with moderate-severe non-diabetic CKD.

Methods

We performed a cross-sectional study of 47 people with CKD (estimated GFR <60 ml/min/1.73 m²) and 29 healthy control subjects. Accelerometry was used to measured physical activity over 7 days, the hyperinsulinemic-euglycemic clamp was used to measure insulin sensitivity, and DXA was used to measured fat mass. We tested associations of physical activity with insulin sensitivity, fat mass, blood pressure, serum lipid concentrations, and serum high sensitivity C-reactive protein concentration using multivariable linear regression, adjusting for possible confounding factors.

Results

Participants with CKD were less active than participants without CKD (mean (SD) 468.1 (233.1) versus 662.3 (292.5) counts per minute) and had lower insulin sensitivity (4.1 (2.1) versus 5.2 (2.0 (mg/min)/(?U/mL)), higher fat mass (32.0 (11.4) versus 29.4 (14.8) kg), and higher triglyceride concentrations (153.2 (91.6) versus 99.6 (66.8) mg/dL). With adjustment for demographics, comorbidity, medications, and estimated GFR, each two-fold higher level of physical activity was associated with a 0.9 (mg/min)/(?U/mL) higher insulin sensitivity (95% CI 0.2, 1.5, p?=?0.006), an 8.0 kg lower fat mass (-12.9, -3.1, p?=?0.001), and a 37.9 mg/dL lower triglyceride concentration (-71.9, -3.9, p?=?0.03). Associations of physical activity with insulin sensitivity and triglycerides did not differ significantly by CKD status (p-values for interaction >0.3).

Conclusions

Greater physical activity is associated with multiple manifestations of metabolic health among people with moderate-severe CKD.

Project description:OBJECTIVES:Elevated risk factors for a number of chronic diseases have been identified in lorry drivers. Unhealthy lifestyle behaviours such as a lack of physical activity (PA) and high levels of sedentary behaviour (sitting) likely contribute to this elevated risk. This study behaviourally phenotyped UK lorry drivers' sedentary and non-sedentary behaviours during workdays and non-workdays and examined markers of drivers cardio-metabolic health. SETTING:A transport company from the East Midlands, UK. PARTICIPANTS:A sample of 159 male heavy goods vehicle drivers (91% white European; (median (range)) age: 50 (24, 67) years) completed the health assessments. 87 (age: 50.0 (25.0, 65.0); body mass index (BMI): 27.7 (19.6, 43.4) kg/m2) provided objective information on sedentary and non-sedentary time. OUTCOMES:Participants self-reported their sociodemographic information. Primary outcomes: sedentary behaviour and PA, assessed over 7 days using an activPAL3 inclinometer. Cardio-metabolic markers included: blood pressure (BP), heart rate, waist circumference (WC), hip circumference, body composition and fasted capillary blood glucose, triglycerides, high-density lipopreotein cholesterol, low-density lipoprotein cholesterol (LDL-C) and total cholesterol (TC) levels. These cardio-metabolic markers were treated as secondary outcomes. RESULTS:Lorry drivers presented an unhealthy cardio-metabolic health profile (median (IQR) systolic BP: 129 (108.5, 164) mm Hg; diastolic BP: 81 (63, 104) mm Hg; BMI: 29 (20, 47) kg/m2; WC: 102 (77.5, 146.5) cm; LDL-C: 3 (1, 6) mmol/L; TC: 4.9 (3, 7.5) mmol/L). 84% were overweight or obese, 43% had type 2 diabetes or prediabetes and 34% had the metabolic syndrome. The subsample of lorry drivers with objective postural data (n=87) accumulated 13?hours/day and 8?hours/day of sedentary behaviour on workdays and non-workdays (p<0.001), respectively. On average, drivers accrued 12?min/day on workdays and 6?min/day on non-workdays of moderate-to-vigorous PA (MVPA). CONCLUSION:Lorry drivers demonstrate a high-risk cardio-metabolic profile and are highly sedentary and physically inactive. Interventions to reduce sitting and increase MVPA during breaks and leisure time to improve cardio-metabolic health are urgently needed. Educational programmes to raise awareness about diet and exercise are recommended.

Project description:BackgroundsDyspepsia is a condition that affects 25% of the U.S. population, and, when associated with pyrosis, its prevalence reaches 40%. Patients with chronic renal insufficiency not only present higher circulating levels of gastrin and gastric dysmotilty, but also make use of a great amount of drugs for the treatment of their comorbidities. This situation increases the chances of developing gastrointestinal symptoms. The aim of the current study is to evaluate the dyspeptic disease profile in patients undergoing hemodialysis, comparing them with chronic renal disease patients in conservative treatment and non-renal injury patients.MethodsThis is a cross sectional study performed at the Gastroenterology department at Faculdade de Medicina do ABC in São Paulo, Brazil. Three groups were set aside according to the renal function levels calculated using the simplified MDRD formula. They answered three questionnaires that evaluated the presence of dyspepsia, functional dyspepsia and gastroesophageal reflux disease (GERD) associated with the performance of high digestive endoscopy.ResultsA significant difference between the groups was observed concerning the renal function evaluated by the rates of creatinine clearance, creatinine and urea (p?<?0.001). The rate of dyspepsia in the control group was higher than in patients with renal function alterations (p?=?0.014). There was no difference between groups when it came to the presence of functional dyspepsia and GERD. However, there was a higher use of proton pump inhibitors in the hemodialysis group than in the other groups (p?<?0.001).ConclusionIn the proposed model, there was no positive correlation between the worsening of the renal function and the presence of dyspepsia, functional dyspepsia and GERD. The longitudinal evaluation of hemodialysis patients is hampered by the high mortality rates in this group. There was a higher use of proton pump inhibitors, and it is believed that the dyspeptic symptoms are not acid-related.

Project description:Background: Health-related quality of life is rapidly becoming recognized as an important indicator of how a disease affects patient lives and for evaluating the quality of care, especially for chronic conditions such as chronic kidney disease (CKD). Objectives: This study is an attempt to assess the quality of life in patients with chronic kidney disease at MMIMSR and also identify characteristics that may be associated with their worsening quality of life. Materials and Methods: This cross-sectional investigation was conducted at the in-patient department (IPD) of the MMIMSR hospital. This study included 105 CKD patients and used a systematic random sampling method for quantitative analysis. This study utilized a 36-item short-form SF-36 (v1.3) questionnaire to assess HRQoL in CKD patients. Descriptive statistics were employed at the baseline. Chi square and ANOVA were used to draw comparisons between two groups or more than two groups, respectively. Logistic regression analysis was utilized to identify the potential QoL determinants. A p value of 0.05 or lower was used to determine statistical significance. Results: Among a total of 105 participants, the mean (±standard deviation) age was found to be 54.53 ± 13.47 years; 48 were male patients, and 57 were female patients. Diabetes Mellitus (61.9%), hypertension (56.2%), chronic glomerulonephritis (7.6%), chronic pyelonephritis (6.7%), and polycystic kidney disease (5.7%) were identified to be the most frequent disorders associated with CKD. The current study also demonstrated that the HRQoL score domains such as symptom problem list, the effect of kidney disease, and the burden of kidney disease decline significantly and progressively as the patient advances into higher stages of CKD (p = 0.005). A similar pattern was observed in work status, sleep, and general health (p < 0.005). Additionally, a statistically significant difference was noted for cognitive function, quality of social interaction, overall health, dialysis staff encouragement, patient satisfaction, social support, physical functioning, role of physical health, pain, emotional well-being, role of emotional health, social functioning, and energy fatigue (p < 0.005). The mean difference for PCS and MCS based on CKD stages was found to be statistically significant (p < 0.005). The PCS and MCS showed a positive correlation with GFR (r = 0.521), and Hb (r = 0.378), GFR (r = 0.836), and Hb (r = 0.488), respectively. Conclusions: The findings of this study demonstrated that a significant decrease in HRQoL was observed among CKD patients, with a progressive deterioration of HRQoL dimensions as the patient advances to end-stage renal disease. This study also revealed that CKD imposes various restrictions on patients' day-to-day lives, particularly in terms of their physical and mental functioning, even in the initial stages of the disease.
