Reduction of appendicular muscle mass (AMM) and muscle strength are related to adverse events in older adults health. However, relation between AMM and muscle strengh of lower and upper limbs with quality of life (QoL) of older adults is not sufficiently understood. Objectives: Evaluate the relation between muscle strength of lower and upper limbs and AMM with QoL of older adults. Methods: Cross-sectional study composed by 399 older adults with 60 to 80 years old community-dwelling. Muscle strength of lower limbs (LL) was evaluated by sit-to-stand test in 30 seconds (SST) and strength of upper limbs (UP) by the test of hand grip strength (HGS). AMM was evaluated by bioelectrical impedance. Data lower than 25 percentiles of LL, UP and AMM by gender were considerate “low AMM” and “low muscle strength”. QoL was evaluated by WHOQOL-BREF questionnaire (general and specifics aspects: Phisical, Psychological, Social, Environmental). General and specifics aspects scores of QoL such as “needs to improve” and “regular” were grouped for multivariate analysis. Results: There was positive correlation between AMM and Pshycological and Social aspects of QoL (r = 0,105-0,121; p < 0,05). There was no correlation between strength of UP and QoL (p > 0,05). Strength of LL was correlated positivily with all the aspects of QoL (r = 0,175-0,343; p < 0,05). Low AMM was related to low QoL in Psychological aspect (prevalence ratio [PR]: 1,30, IC 95% 1,12–1,52). Low muscle strength of UP were associated to low general QoL (PR: 1,09, IC 95% 1,01–1,17). Low muscle strength of LL were associated to low general QoL (PR: 1,20, IC 95% 1,05–1,39), physical aspect (PR: 1,34, IC 95% 1,10–1,63), psychological (PR: 1,34, IC 95% 1,10–1,63) and environmental (PR: 1,12, IC 95% 1,00–1,24). Conclusion: Muscle strength, lower limbs mainly, was related to quality of life in older adults community-dwelling but did not with appendicular muscle mass and strength of UPAcesso AbertoEnvelhecimentoBioimpedânciaForça do aperto de mãoTeste de sentar e levantarQualidade de vida relacionada à saúdemasterThesis
