Eating As Treatment (EAT): A stepped wedge, randomised control trial of a health behaviour change intervention provided by dietitians to improve nutrition in head and neck cancer patients undergoing radiotherapy

维持头颈癌（HNC）患者的营养具有挑战性。放疗和癌症的负担使HNC患者难以维持足够的营养。HNC患者也有更高水平的精神疾病和物质依赖，包括酒精滥用。这项试验旨在建立在有希望的试点数据的基础上，首次评估营养师提供的健康行为干预（饮食作为治疗），以改善HNC患者的营养状况。

Maintaining nutrition in Head and Neck Cancer (HNC) patients is challenging. Radiotherapy and the burden of the cancer make it difficult for HNC patients to maintain sufficient nutrition. HNC patients also have higher levels of mental illness and substance dependence including alcohol misuse. This trial aims to build on promising pilot data to evaluate for the first time a dietitian delivered health behaviour intervention (Eating As Treatment) to improve nutritional status among HNC patients.
