The work ability index and functional capacity among older workers.

BACKGROUND: Decreases in functional ability due to aging can impair work capacity and productivity among older workers. OBJECTIVE: This study compares the sociodemographics, health conditions, and physical functioning abilities of young and old workers as well as correlates of physical functioning capacity with the work ability index (WAI). METHOD: This exploratory, cross-sectional study examined employees of a higher education institution (HEI) and those of a metallurgical industry. Older workers (50 years old or above) were matched for gender and occupation type with younger workers (less than 50 years old). The following evaluations were applied: the multidimensional assessment questionnaire (which included sociodemographic, clinical, health perception, and physical health indices), the WAI, and a battery of physical functional tests. RESULTS: Diseases and regularly used medications were more common among the group of aging workers. The WAI did not differ between groups (p=0.237). Both groups showed similar physical functional capacity performances with regard to walking speed, muscle strength, and lower limb physical functioning. Aging workers showed a poorer performance on a test of right-leg support (p=0.004). The WAI was moderately correlated with the sit-to-stand test among older female workers (r=0.573, p=0.051). CONCLUSIONS: Unfavorable general health conditions did not affect the assessment of work ability or most of the tests of physical functional capacity in the aging group.

CONTEXTUALIZAÇÃO: O declínio da capacidade funcional, decorrente do envelhecimento, pode comprometer a capacidade para o trabalho e a produtividade dos trabalhadores mais velhos. OBJETIVO: Comparar o perfil sociodemográfico, as condições de saúde e a capacidade físico-funcional de trabalhadores jovens e mais velhos e correlacionar as medidas físico-funcionais ao índice de capacidade para o trabalho (ICT). MÉTODO: Estudo exploratório, transversal, com trabalhadores de uma Instituição de Ensino Superior e uma Indústria Metalúrgica. Os trabalhadores mais velhos (50 anos ou mais) foram pareados em relação ao gênero e ao tipo de ocupação a trabalhadores jovens (menos de 50 anos). Foram utilizados questionário de avaliação multidimensional, contendo dados sociodemográficos, clínicos, percepção da saúde e saúde física, o ICT e uma bateria de testes físico-funcionais. RESULTADOS: O número de doenças e número de medicamentos de uso regular foram maiores para o grupo de trabalhadores mais velhos. O ICT não apresentou diferença entre os grupos (p=0,237). A capacidade físico-funcional revelou desempenho similar entre os grupos em medidas de velocidade de caminhada, de força muscular e de função física de MMII. Os trabalhadores mais velhos apresentaram um pior desempenho apenas no teste de apoio unipodal direito (p=0,004). O ICT se mostrou correlacionado de forma moderada ao sit-to-stand test entre as mulheres do grupo de trabalhadores mais velhos (r=0,573, p=0,051). CONCLUSÃO: A avaliação da capacidade para o trabalho e a maior parte dos testes de capacidade físico-funcional no grupo mais velho parecem não ter sido ...
