Association between hand grip strength and spirometric parameters: Korean National health and Nutrition Examination Survey (KNHANES)
Abstract
Background: We investigated the associations between hand grip strength (HGS) and spirometric parameters.
Methods: A total of 5,303 participants over 40 years of age, who underwent spirometry and HGS testing, were selected from the Korean National Health and Nutrition Examination Survey 2014–2015. Outcome measures were forced expiratory volume in 1 s (FEV1), forced vital capacity (FVC), FEV1/FVC, and peak expiratory flow rate (PEFR). Unadjusted and adjusted linear regressions were used for the analyses.
Results: Mean HGS in the obstructive group was: male: 38.9±6.9 kg; female: 24.2±4.8 kg, which was significantly less than that in the normal group (male: 42.2±7.2 kg, P<0.001; female: 26.0±4.6 kg, P<0.001). In a multiple linear regression model, HGS was significantly associated with FEV1 (male: β=0.18, P<0.001, female: β=0.21, P<0.001), FVC (male: β=0.23, P<0.001, female: β=0.24, P<0.001) and PEFR (male: β=0.13, P<0.001, female: β=0.14, P<0.001) after adjustment.
Conclusions: We found associations between muscle strength as evaluated by HGS and spirometric pulmonary function parameters.
