A cross-sectional study was conducted to explore the association between soft drink consumption and handgrip strength (HGS) in subjects aged 40 years and older (n = 14,925). After multivariable-adjustment (including demographics, lifestyles, family history of diseases, dietary intake, and other beverages consumption), the least square means (95% confidence interval) of HGS across soft drink consumption categories were 43.1(42.7, 43.5) kg for almost never drink, 42.9(42.4, 43.4) kg for <1 cup/week, 42.8(42.1, 43.5) kg for 1-6 cups/week and 41.2(40.1, 42.6) kg for ≥1 cup/day (p for trend < 0.001) in men, and 26.6(25.9, 27.8) kg for almost never drink, 26.5(25.8, 27.1) kg for <1 cup/week, 26.3(25.7, 27.2) kg for 1-6 cups/week and 25.2(24.9, 27.0) kg for ≥1 cup/day (p for trend < 0.001) in women, respectively. Our findings suggest that higher consumption of soft drinks was significantly associated with lower HGS in middle-aged and older adults. Additional prospective or interventional studies are needed to confirm this issue.
