This article assesses the role played by media in contributing to the current epidemic of childhood obesity. Electronic media use, often referred to as screen time, is significantly correlated with child adiposity. Although the causal mechanism that accounts for this relationship is unclear, it is well established that reducing screen time improves weight status. Media advertising for unhealthy foods contributes to obesity by influencing children's food preferences, requests, and diet. Industry efforts have failed to improve the nutritional quality of foods marketed on television to children, leading public health advocates to recommend government restrictions on child-targeted advertisements for unhealthy foods.
本文评估了媒体在促成当前儿童肥胖症流行中所扮演的角色。电子媒体的使用，通常被称为屏幕时间，与儿童肥胖密切相关。虽然造成这种关系的因果机制尚不清楚，但减少屏幕时间确实可以改善体重状况。媒体对不健康食品的广告宣传通过影响儿童的食物偏好、要求和饮食来导致肥胖。行业的努力未能提高电视上针对儿童的广告食品的营养质量，这导致公共卫生倡导者建议政府限制针对儿童的不健康食品广告。
