Normalized handgrip strength and future risk of hypertension: findings from a prospective cohort study.

Abstract

Previous reports of an association between handgrip strength (HGS) and the risk of hypertension have utilized cross-sectional designs. We aimed to assess the prospective association between HGS and hypertension risk in a general population. Handgrip strength was assessed at baseline in 463 Finnish men and women aged 61-73 years. Handgrip strength was normalized (HGS/body weight^2/3). After 16 years median follow-up, 110 hypertension cases occurred. Comparing the extreme tertiles of normalized HGS, the multivariable adjusted hazard ratio (95% CI) for hypertension was 0.63 (0.38-1.04). Previous evidence of associations may have been driven by study design limitations such as lack of temporality.
