摘要
目的本研究旨在探索安徽省初中生零食选择偏好及其影响因素,为制定初中生饮食行为干预方案提供科学依据。方法基于离散选择实验设计问卷,采用分层整群随机抽样方法,在安徽省2个城市抽取443名初一和初二学生进行问卷调查。应用Stata16.0软件建立混合Logit模型,分析初中生的零食偏好并计算支付意愿。结果价格、口味、营养、购买地点、选择依据等因素对初中生的零食偏好有显著影响。初中生对富含膳食纤维、家人常吃的零食有正向偏好,且愿意为富含膳食纤维的零食多支付9.276元。城市初中生更偏好口味和营养,农村初中生更偏好营养和购买地点。结论初中生在选择零食时更关注零食的营养成分和选择依据,家庭及学校应采取健康促进措施,帮助其建立健康的饮食行为。
