RESUMO
Background The measurement of handgrip strength (HGS) has prognostic value with respect to all-cause mortality, cardiovascular mortality and cardiovascular disease, and is an important part of the evaluation of frailty. Published reference ranges for HGS aremostly derived from Caucasian populations in high-income countries. There is a paucity of information on normative HGS valuesin non-Caucasian populations from low- or middle-income countries. The objective of this study was to develop reference HGS rangesfor healthy adults from a broad range of ethnicities and socioeconomically diverse geographic regions. Methods HGS was measured using a Jamar dynamometer in 125,462 healthy adults aged 35-70 years from 21 countries inthe Prospective Urban Rural Epidemiology (PURE) study. Results HGS values differed among individuals from different geographic regions. HGS values were highest among thosefrom Europe/North America, lowest among those from South Asia, South East Asia and Africa, and intermediate among thosefrom China, South America, and the Middle East. Reference ranges stratified by geographic region, age, and sex are presented. These ranges varied from a median (25th75th percentile) 50 kg (4356 kg) in men 60 years from South East Asia. Reference ranges by ethnicity and body-mass index are also reported...
