Introdução: As alterações da meia-idade são influenciadas, entre outros, por aspetos hormonais (e.g., devido à diminuição do estrogênio há aumento da gordura abdominal) e culturais. Estas alterações podem influenciar a perceção da imagem corporal feminina e, por conseguinte, o uso de estratégias de gestão de peso (avaliadas pelo Oxford Food and Activity Behaviors for Middle-Aged Women - OxFAB-MAW).
Objetivo: Este estudo pretende validar a OxFAB-MAW para esta amostra de mulheres brasileiras e aferir se: a preocupação com a imagem corporal, variáveis sociodemográficas (e.g., renda familiar mensal), de saúde (e.g., Índice de Massa Corporal), de menopausa (e.g., estado de menopausa) e de estilo de vida (e.g., consumo de bebidas alcoólicas) influenciam o uso de estratégias de gestão de peso nestas mulheres.
Método: 254 participantes brasileiras entre os 40-65 anos (M=48.92; DP=7.34) completaram o Body Shape Questionnaire (BSQ-8B), o OxFAB-MAW e um questionário sociodemográfico, de menopausa, saúde e estilo de vida. A validade do construto, convergente, a consistência interna, a fiabilidade do construto, a sensibilidade e os pesos fatoriais da OxFAB-MAW foram avaliados. Foi analisado um modelo preditivo que avaliou a influência de várias variáveis nos domínios da OxFAB-MAW. Resultados: A OxFAB-MAW demonstrou ter propriedades psicométricas adequadas nesta amostra, à excepção de 2 domínios (com valores sofríveis de consistência interna e de fiabilidade do construto). O modelo preditivo demonstrou que menores rendas familiares mensais e o consumo de bebidas alcoólicas predizem a frequência do uso de determinadas estratégias de gestão de peso.
Conclusões: A OxFAB-MAW demonstra ser culturalmente sensível na avaliação das estratégias de gestão de peso nesta amostra. Este estudo pode contribuir para aprofundar a influência de fatores psicossociais na relação destas mulheres com os seus corpos e os comportamentos de saúde ou de risco que adotam para gerir o seu peso. Além de informar intervenções e políticas públicas eficazes e culturalmente ajustadas às necessidades dessa população.
Introduction: Midlife changes are influenced, among other factors, by hormonal (e.g., a decrease in estrogen levels to increased abdominal fat) and cultural aspects. These changes can impact women's perception of body image and, consequently, the use of weight management strategies (as assessed by the Oxford Food and Activity Behaviors for Middle-Aged Women – OxFAB-MAW). Objective: This study aims to validate the OxFAB-MAW for a sample of Brazilian women and to investigate whether body image concerns, sociodemographic variables (e.g., monthly household income), health indicators (e.g., Body Mass Index), menopausal status (e.g., menopausal stage), and lifestyle factors (e.g., alcohol consumption) influence the use of weight management strategies in this population. Method: A total of 254 Brazilian women aged 40 to 65 years (M=48.92; SD=7.34) completed the Body Shape Questionnaire (BSQ-8B), the OxFAB-MAW, and a sociodemographic, menopausal, health, and lifestyle questionnaire. Construct and convergent validity, internal consistency, construct reliability, sensitivity, and factor loadings of the OxFAB-MAW were assessed. A predictive model was analyzed to examine the influence of various variables on the OxFAB-MAW domains. Results: The OxFAB-MAW demonstrated adequate psychometric properties in this sample, with the exception of two domains that showed weak internal consistency and construct reliability. The predictive model indicated that lower monthly household income and alcohol consumption predicted the frequency of use of certain weight management strategies. Conclusions: The OxFAB-MAW appears to be culturally sensitive for assessing weight management strategies in this sample. This study contributes to a deeper understanding of the influence of psychosocial factors on women’s relationships with their bodies and the health or risk behaviors they adopt to manage their weight. It also offers insights for the development of effective and culturally appropriate interventions and public health policies tailored to the needs of this population.
