BACKGROUND & AIMS: Although maximal voluntary handgrip strength (HGS) is considered a reliable tool in nutritional assessment there are few reference data available. This paper presents reference values for handgrip strength of healthy adults (age > or = 20 years) from a household survey.
Data were obtained from a representative sample of adults (1122 males and 1928 females) living in Niterói, Rio de Janeiro, Brazil. HGS was measured three times with a Jamar mechanical dynamometer in both hands and the highest value used in the analysis. The percentile distribution of HGS was calculated according to sex and age categories.
Mean values of right and left HGS were 42.8 and 40.9 kg for males, and 25.3 and 24.0 kg for females, respectively. HGS increased with age and significantly decreased after 40 and 50 year-olds for women and men, respectively. Body mass index (BMI) was associated with HGS in both sexes but only underweight male subjects had significantly lower HGS values.
The highest HGS values are observed at the 4th decade of life with significant declines thereafter. HGS is significantly associated with BMI. The reference values of HGS may be useful in assessing the nutritional status of similar adult urban population.
尽管最大自主握力（HGS）被认为是营养评估中的一种可靠工具，但可用的参考数据很少。本文展示了一项家庭调查中健康成年人（年龄≥20岁）握力的参考值。
数据来自居住在巴西里约热内卢尼泰罗伊的成年人代表性样本（1122名男性和1928名女性）。使用Jamar机械测力计对双手进行三次握力测量，并将最高值用于分析。根据性别和年龄类别计算握力的百分位数分布。
男性右、左手握力的平均值分别为42.8千克和40.9千克，女性分别为25.3千克和24.0千克。握力随年龄增长，女性在40岁、男性在50岁之后握力显著下降。体重指数（BMI）与两性的握力均相关，但只有体重过轻的男性受试者握力值显著较低。
在生命的第四个十年观察到最高的握力值，此后显著下降。握力与BMI显著相关。握力的参考值可能有助于评估类似城市成年人群的营养状况。
