 The Northwest Adelaide Health Study is a longitudinal cohort study of people aged 18 years and over, aimed at describing normative data for hand-grip strength in a community-based Australian population. Secondary aims were to investigate the relationship between body mass index, BMI, and hand-grip strength, and to compare Australian data with international hand-grip strength norms. The sample was randomly selected and recruited by telephone interview, with 3,206 participants returning for the second stage of the study. Following exclusion of participants with hand pain or arthritis, 1,366 men and 1,312 women provided hand-grip strength measurements. The study population was relatively young, with 41.5% under 40 years, and their mean BMI was 28.1 kilograms per square meter, SD 5.5. Higher hand-grip strength was weekly related to higher BMI in adults under the age of 30 and over the age of 70, but inversely related to higher BMI between these ages. Australian norms from this sample had amongst the lowest of the hand-grip strength of the internationally published norms, except those from underweight populations. The age and gender grip strength values are lower in younger adults than those reported in international literature.
