RESUMEN
INTRODUCTION: Handgrip strength is a robust indicator of the biological health of elderly. OBJECTIVE: The purpose of this study is twofold: 1) estimate the normative values of absolute and relative handgrip strength, specific to adults over 60 years of age in Colombia, using quantile regression models: 2) compare the normative values of absolute and relative handgrip strength in Colombian older adults with those from different countries. METHODS: A cross-sectional analysis of a sample of 5377 older adults. Handgrip strength was evaluated with a TKK 5101 digital dynamometer (Takei Scientific Instruments Co., Ltd., Tokyo, Japan). Relative handgrip strength was estimated by dividing by weight in kilograms. The absolute and relative handgrip strength normative values were estimated through quantile regression models for the percentiles P5, P10, P25, P50, P75, P90 and P95, they were developed independently for each sex; all analyzes were adjusted for the expansion factor. RESULTS: Absolute handgrip strength values were considerably higher in men (P50 60-64 years = 32.0 kg, P50 >85 years = 18.0 kg) compared to women (P50 60-65 years = 19.0 kg; P50 >85 years = 12.0 kg), in all age groups. Additionally, as age increases in both sexes, there is a decrease in the values of absolute and relative manual grip strength. CONCLUSIONS: The estimated normative values in the Colombian population were generally lower than those reported in other studies around the world. These results could be related with methodologies used variability to evaluate handgrip strength and the estimation methods, which could influence the discrepancies between the different reports.
