Introdução: Nos últimos anos, tem-se verificado um aumento crescente do número de sobreviventes de cancro da mama o que implica uma vivência com as complicações crónicas resultantes do tratamento. Complicações essas que têm um impacto negativo na função, na participação e na qualidade de vida desta população. O desenvolvimento de linfedema (LE) é uma das principais complicações e preocupações que advêm do tratamento do cancro da mama e como tal, torna-se fulcral perceber qual a melhor forma de prevenir e tratar o desenvolvimento do mesmo. A prática de atividade física (AF) desencadeia uma série de benefícios clínicos, tendo sido demonstrado eficácia, segurança e viabilidade no controle das complicações subsequentes aos tratamentos do cancro da mama e na melhoria da função e qualidade de vida da população em estudo. Objetivo: Caracterizar os níveis de atividade física em mulheres sobreviventes do cancro da mama. Métodos: Foi realizado um estudo transversal analítico e foram selecionadas mulheres sobreviventes de cancro da mama, com 1 e 5 anos de pós-operatório. Foi aplicado um questionário de caracterização, foi medido o volume de LE dos membros superiores através da perimetria, foi avaliada a força de preensão palmar com o dinamómetro JAMAR, foi aplicado o questionário IPAQ-SF e foi colocado o acelerómetro Actigraph®. Resultados: A amostra é constituída por 46 mulheres com média de 37.5±14.1 meses de cirurgia mamária. Verificou-se que 50% da amostra apresentava excesso de peso e 28.3% obesidade. Verificou-se uma média de 1.2±0.1 METs, 8.3±1.8 horas por dia em atividade sedentária, despendendo em uma média 61% do tempo acordados em atividade sedentária. Foram encontradas correlações significativas entre a força de preensão do lado afetado e a diferença de volume entre os MS (rp=-0.303, p=0.041), bem como entre o índice de massa corporal (IMC) e a diferença de volume entre os MS (rp=0.34; p=0.02). Adicionalmente, foi encontrada uma correlação significativa entre o IMC e o volume do MS afetado (rp=0.85, p=.000). Conclusões: Embora a AF não possa prevenir diretamente a LE, pode desempenhar um papel importante na prevenção indireta do seu desenvolvimento, ajudando a controlar o IMC e promovendo níveis mais altos de força de preensão.
ABSTRACT - Introduction: In recent years, there has been an increase in the number of breast cancer survivors, which means living with the chronic complications resulting from treatment. These complications harm the function, participation, and quality of life of this population. The development of lymphedema (LE) is one of the major complications and concerns arising from breast cancer treatment, and as such it is crucial to understand the best way to prevent and treat its development. The practice of physical activity (PA) triggers several clinical benefits and is effective, safe, and feasible in controlling complications following breast cancer treatment and in improving function and quality of life in the study population. Objective: To characterize physical activity levels in breast cancer survivors. Methods: An analytical cross-sectional study was performed, selecting women who had survived breast cancer, 1 and 5 years after surgery. A characterization questionnaire was administered, upper limb LE volume was measured by perimetry, palmar grip strength was assessed with the JAMAR dynamometer, the IPAQ-SF questionnaire was administered, and the Actigraph® accelerometer was placed. Results: The sample consists of 46 women with a mean of 37.5±14.1 months since breast surgery. It was found that 50% of the sample was overweight and 28.3% was obese. There was a mean of 1.2±0.1 METs, 8.3±1.8 hours per day in sedentary activity, with a mean of 61% of waking time spent in sedentary activity. Significant correlations were found between grip strength on the affected side and the difference in volume between UL (rp=-0.303, p=0.041), and between body mass index (BMI) and the difference in volume between UL. MS (rp=0.34; p=0.02). Additionally, a significant correlation was found between BMI and the affected UL volume (rp=0.85, p=.000). Conclusions: Although PA cannot directly prevent LE, it can play an important role in indirectly preventing its development by helping to control BMI and promoting higher levels of grip strength.
