Insights
Higher handgrip strength and faster walking pace are linked to a lower risk of developing chronic kidney disease (CKD). These physical indicators show a significant inverse relationship with incident CKD in the general population.
Area of Science:
- Gerontology
- Nephrology
- Epidemiology
Background:
- Uncertainty exists regarding the individual and combined effects of handgrip strength and walking pace on chronic kidney disease (CKD) risk.
- Large-scale observational data from the UK Biobank were utilized to address this knowledge gap.
Purpose of the Study:
- To investigate the relationship between handgrip strength and/or walking pace and the incidence of CKD.
- To determine if these physical parameters serve as predictive markers for CKD development.
Main Methods:
- Analysis of data from 417,504 participants in the UK Biobank, free of pre-existing kidney disease.
- Handgrip strength measured by dynamometer; walking pace self-reported (slow, average, brisk).
- Cox proportional hazards models employed to calculate hazard ratios (HRs) and 95% confidence intervals (CIs) for incident CKD.
Main Results:
- Over a median follow-up of 12.1 years, 11,064 (2.7%) participants developed incident CKD.
- Both higher handgrip strength and faster walking pace were significantly inversely associated with CKD risk.
- The lowest risk of incident CKD was observed in participants with both higher handgrip strength and average or brisk walking pace.
Conclusions:
- Handgrip strength and walking pace are significant inverse predictors of incident CKD in the general population.
- These easily measurable physical attributes may play a role in assessing CKD risk.
Background:
The individual and combined relations of handgrip strength and walking pace with the risk of chronic kidney disease (CKD) remain uncertain. We aimed to investigate the relationship of handgrip strength and/or walking pace with incident CKD, using data from the large-scale, observational UK Biobank.
Methods:
A total of 417 504 participants free of prior kidney diseases were included from UK Biobank. Handgrip strength was assessed by dynamometer. The walking pace was self-reported as slow, average, or brisk. Cox proportional hazards models were applied to calculate hazard ratios (HRs) and 95% confidence intervals (CIs) for incident CKD.
Results:
The average age of the study population was 56.3 (SD, 8.1) years. 192 012 (46.0%) of the participants were male. The mean handgrip strength was 23.5 (SD, 6.2) and 40.0 (SD, 8.8) kg for females and males, respectively. Over a median follow-up duration of 12.1 years, 11 064 (2.7%) participants developed incident CKD. Handgrip strength was significantly inversely associated with the risk of incident CKD in both males and females (both P for trend <0.001). When handgrip strength was assessed as sex-specific quartiles, compared with those in the first quartile, the adjusted HRs (95% CI) of incident CKD in participants in the second, third and fourth quartiles were 0.84 (0.79, 0.89), 0.76 (0.71, 0.81) and 0.72 (0.67, 0.77), respectively. Compared with those with slow walking pace, participants with average (HR, 0.64; 95% CI: 0.60-0.68) or brisk (HR, 0.53; 95% CI: 0.49-0.57) walking pace had significantly lower risks of incident CKD. Compared with those with both lower handgrip strength (the first quartile) and slow walking pace, the lowest risk of incident CKD was observed in participants with both higher handgrip strength (the 2-4 quartiles) and average or brisk walking pace (HR, 0.51; 95% CI: 0.46-0.55).
Conclusions:
Handgrip strength and walking pace were significantly inversely associated with incident CKD in the general population.
