Impact of shoe size in a sample of elderly individuals / Impacto do tamanho do calçado em uma amostra de idosos

Summary Introduction: The use of an improper shoe size is common in older people and is believed to have a detrimental effect on the quality of life related to foot health. The objective is to describe and compare, in a sample of participants, the impact of shoes that fit properly or improperly, as well as analyze the scores related to foot health and health overall. Method: A sample of 64 participants, with a mean age of 75.3±7.9 years, attended an outpatient center where self-report data was recorded, the measurements of the size of the feet and footwear were determined and the scores compared between the group that wears the correct size of shoes and another group of individuals who do not wear the correct size of shoes, using the Spanish version of the Foot Health Status Questionnaire. Results: The group wearing an improper shoe size showed poorer quality of life regarding overall health and specifically foot health. Differences between groups were evaluated using a t-test for independent samples resulting statistically significant (p<0.05) for the dimension of pain, function, footwear, overall foot health, and social function. Conclusion: Inadequate shoe size has a significant negative impact on quality of life related to foot health. The degree of negative impact seems to be associated with age, sex, and body mass index (BMI).

Resumo Introdução: o uso de sapatos com tamanhos inadequados é comum em pessoas idosas e acredita-se resultar em efeito negativo sobre a qualidade de vida relacionada à saúde do pé. O objetivo é descrever e comparar o impacto de uma amostra de participantes usando calçados de tamanho adequado e indivíduos com calçados de tamanho inadequado, e as pontuações relacionadas com a saúde do pé e geral. Método: de uma amostra de 64 participantes, com idade média de 75,3±7,9, de um centro ambulatorial, dados de autorrelato foram registrados e medidas do tamanho dos pés e dos calçados foram determinadas. Os escores foram comparados pelo Foot Health Status Questionnaire, na versão em espanhol, entre os grupos que usavam sapatos de tamanhos corretos e incorretos. Resultados: o grupo que utilizava sapatos inadequados mostrou pior qualidade de vida relacionada à saúde geral e no pé. Diferenças entre os grupos foram avaliadas utilizando o teste t para amostras independentes, sendo estatisticamente significativas (p<0,05) para dimensão da dor, função, calçados, saúde geral, do pé e função social. Conclusão: o uso de calçado inadequado tem um impacto negativo significativo sobre a qualidade de vida relacionada à saúde do pé. O grau de impacto negativo parece estar associado com idade, sexo e índice de massa corpórea (IMC).

Alterações podais e mobilidade em idosos atendidos em um ambulatório de geriatria / Modificaciones podales y movilidad en ancianos asistidos en un ambulatorio de geriatría / Podal changes and mobility in elderly assisted in geriatric outpatient clinic

Objective: to determine the most frequentpodal changes and their harm in the mobility in elderly outpatients. Method: this descriptive study was conducted with 121 elderly people who were treated in a geriatric outpatient clinic of a university hospital. Data were collected through interviews subsidized by structured tool and analyzed using descriptive and inferential statistics. Results: we observed high incidence of feet problems, especially in women and the young elderly, highlighting foot pain in the majority of respondents. There was also a predominance of elderly with partial independence. Conclusion: it is identified the need for special attention to the health of aged people who reports pain in feet, since this tends to restrict their usual activities, causing decreased quality of life, immobilization and possible falls.

Objetivo: verificar alterações podais mais frequentes e o prejuízo destas na mobilidade de idosos em atendimento ambulatorial. Método: estudo descritivo, realizado com 121 idosos que foram atendidos em um ambulatório de geriatria de um hospital universitário. Os dados foram coletados através de entrevista subsidiada por instrumento estruturado e analisados por meio de estatística descritiva e inferencial. Resultados: verificou-se alta incidência de problemas podais, especialmente nas mulheres e idosos jovens, destacando a ocorrência do pé doloroso na maioria dos entrevistados. Houve também predominância de idosos com independência parcial. Conclusão: identifica-se a necessidade de atenção especial à saúde do idoso que relata dor nos pés, visto que este tende a restringir suas atividades habituais, causando diminuição da qualidade de vida, imobilização e possíveis episódios de quedas.

Objetivo: verificar las modificaciones podales más frecuentes y el perjuicio de estas en la movilidad de ancianos en una clínica geriátrica. Método: estudio descriptivo, realizado con 121 ancianos que fueron asistidos en un ambulatorio de geriatría de un hospital universitario. Los datos fueron recolectados através de entrevistas subvencionadas por instrumento estructurado y analizados mediante estadística descriptiva e inferencial. Resultados: se verificó alta incidencia podales, especialmente entre las mujeres y ancianos jóvenes, destacando la ocurrencia del pie doloroso en la mayoría de los encuestados. También hubo un predominio de pacientes de edad avanzada con independencia parcial. Conclusión: se identifica la necesidad de prestar especial atención a salud del anciano que relata dolor en los pies, ya que este tiende a restringir sus actividades diarias, causando disminución de la calidad de vida, inmovilización y posibles episodios de caídas.

Brazilian version of the foot health status questionnaire (FHSQ-BR): cross-cultural adaptation and evaluation of measurement properties

OBJECTIVE: To conduct a cross-cultural adaptation of the Foot Health Status Questionnaire into Brazilian-Portuguese and to assess its measurement properties. INTRODUCTION: This instrument is an outcome measure with 10 domains with scores ranging from 0-100, worst to best, respectively. The translated instrument will improve the examinations and foot care of rheumatoid arthritis patients. METHODS: The questions were translated, back-translated, evaluated by a multidisciplinary committee and pre-tested (n = 40 rheumatoid arthritis subjects). The new version was submitted to a field test (n = 65) to evaluate measurement properties such as test-retest reliability, internal consistency and construct validity. The Health Assessment Questionnaire, Numeric Rating Scale for foot pain and Sharp/van der Heijde scores for foot X-rays were used to test the construct validity. RESULTS: The cross-cultural adaptation was completed with minor wording adaptations from the original instrument. The evaluation of measurement properties showed high reliability with low variation coefficients between interviews. The a-Cronbach coefficients varied from 0.468 to 0.855, while correlation to the Health Assessment Questionnaire and Numeric Rating Scale was statistically significant for five out of eight domains. DISCUSSION: Intra- and inter-observer correlations showed high reliability. Internal consistency coefficients were high for all domains, revealing higher values for less subjective domains. As for construct validity, each domain revealed correlations with a specific group of parameters according to what the domains intended to measure. CONCLUSION: The FHSQ was cross-culturally adapted, generating a reliable, consistent, and valid instrument that is useful for evaluating foot health in patients with rheumatoid arthritis.
