Barriers to physical activity and healthy diet among breast cancer survivors: A multilevel perspective.
Sommaire de l'article
Cancer survivors engage in suboptimal levels of health behaviours and report many barriers to health behaviours, but we lack a solid understanding of the different levels of barriers and how they relate to enacted health behaviours. To address these issues, we conducted mixed-method research in 97 breast cancer survivors. Participants' barriers to physical activity (PA) and healthy diet, asked as an open-ended question, were coded as individual-level, social-level, and organisational/environmental-level for each health behaviour. Moderate-to-vigorous PA and fruit and vegetable (F&V) intake were assessed. Most participants perceived at least one PA (72.7%) and diet (64.9%) individual-level barrier (e.g. physical symptoms/injury); only 15.2% (PA) and 15.6% (diet) reported at least one social-level barrier (e.g. family obligations). About 28.8% (PA) and 29.9% (diet) perceived at least one organisational/environmental-level barrier (e.g. job demand, cost of F&V). Survivors perceiving individual-level dietary barriers consumed less F&V (-.65 servings/day) than those not perceiving dietary barriers at this level. Survivors perceiving social-level dietary barriers reported marginally lower F&V intake (-.65 servings/day) than their counterparts. Those perceiving organisational/environmental-level PA barriers reported marginally fewer minutes (-44.30/week) of moderate-to-vigorous PA than their counterparts. Barriers at multiple levels should be addressed to improve health behaviours among breast cancer survivors.
