Water Intake and Handgrip Strength in US Adults: A Cross-Sectional Study Based on NHANES 2011–2014 Data

Abstract

This study aimed to examine the relationship between daily total intake of water (DTIW) and handgrip strength (HGS) among US adults and to explore the impact of water intake on muscle function and health, providing a reference for public health policies and health education. Using the data from the National Health and Nutrition Examination Survey (NHANES) 2011–2014, a cross-sectional survey design was adopted to analyze 5427 adults (48.37% female and 51.63% male) aged 20 years and above. DTIW was assessed using two non-consecutive 24 h dietary recall interviews, and the HGS level was measured using a Takei Dynamometer. Weighted generalized linear regression models and restricted cubic spline plots were used to analyze the linear and nonlinear associations between DTIW and HGS level and to conduct a gender subgroup analysis and an interaction effect test. The results showed that there were significant differences in HGS and other characteristics among different quartile groups of DTIW (p < 0.05). There was a significant nonlinear trend (exhibiting an inverted U-curve) between DTIW and HGS (p for nonlinear = 0.0044), with a cut-off point of 2663 g/day. Gender subgroup analysis showed that the nonlinear trend (exhibiting an inverted U-curve) was significant only in males (p for nonlinear = 0.0016), with a cut-off point of 2595 g/day. None of the stratified variables had an interaction effect on the association between DTIW and HGS (p for interaction > 0.05). In conclusion, this study found a nonlinear association between DTIW and HGS levels, as well as a gender difference. This finding provides new clues and directions for exploring the mechanism of the impact of DTIW on muscle function and health and also provides new evidence and suggestions for adults to adjust their water intake reasonably.

Seasonality Affects Fluid Intake Behaviors among Young Adults in Hebei, China

“…In line with the results from the present study, a recent survey among 2233 Chinese residents in 27 cities reported a significantly higher TFI in males than females regardless of age group [ 21 ]. Wu et al [ 22 ] also found a significant difference in daily TWI between US males and females based on the National Health and Nutrition Examination Survey 2011–2014 data. According to the results of the GEE analysis, gender was significantly associated with TDF.…”

Synergistic Effects of Nutrients on Musculoskeletal Health in Gerontology: Understanding the Combined Impact of Macronutrients and Micronutrients

“…Adequate water intake helps maintain the balance of intracellular and extracellular fluids, promotes smooth blood circulation, enhances the delivery efficiency of nutrients and hormones, supports normal nervous system function, and improves the excitability and conduction speed of motor neurons. This, in turn, increases the contractile capacity and strength of muscle fibers [ 24 , 25 ].…”

The association between polyunsaturated fatty acids and periodontitis: NHANES 2011–2014 and Mendelian randomisation analysis

“…A total cholesterol concentration ≥ 200 mg/dL, triglyceride concentration ≥ 150 mg/dL, male HDL concentration < 40 mg/dL, female HDL concentration < 50 mg/dL, and low-density lipoprotein cholesterol concentration ≥ 130 mg/dL were the criteria for hyperlipidaemia. Additionally, the use of cholesterol-lowering drugs was also defined as hyperlipidaemia [21].…”
