Sarcopenia, low muscle strength and mass, and hand grip strength (HGS) are known to predict reduced independence in people in their seventies. This paper investigates these relationships in New Zealand octogenarians, including Indigenous M\u0101ori.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>This study used data from Life and Living in Advanced Age: A Cohort Study in New Zealand (LiLACS NZ), which recruited 421 M\u0101ori and 516 non-M\u0101ori in 2010-2011. The Nottingham Extended Activities of Daily Living (NEADL) scale measured independence. Participants were classified by ethnicity (M\u0101ori or non-M\u0101ori) and sex into high, medium or low independence trajectory groups based on their six annual NEADL scores using group-based trajectory modelling. The associations between HGS or probable sarcopenia (a binary measure of HGS) and independence trajectory group (high, medium, low) were tested separately by ethnicity and sex in multinomial logistic regression models.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Hand grip strength was inversely associated with low (versus medium) independence trajectory among M\u0101ori women, non-M\u0101ori women and non-M\u0101ori men, adjusting for age, comorbidities and cognition (adjusted odds ratio, aOR, 0.84 (95% CI 0.72, 0.97), 0.86 (0.77, 0.96) and 0.90 (0.81, 0.99), respectively).
