Childhood obesity has emerged as a public health concern in Canada. It has been suggested that excessive screen viewing (i.e., television, computer, video) is a major factor contributing to the increased risk of obesity in children. Exploring young children's experiences with this modifiable behavior may be beneficial to the creation of a multifaceted program aimed at the primary prevention of obesity.
To seek parents' perceptions and insights pertaining to their preschoolers' screen-viewing behaviors.
This qualitative study targeted a heterogeneous sample of parents with children aged 2.5 to 5 years. Two experienced moderators using a semistructured interview guide conducted the ten focus groups between September and November 2003. All focus groups were audio-recorded and transcribed verbatim. In fall 2003 to spring 2004, inductive content analysis was conducted independently by a minimum of two qualitative researchers.
Many parents were not concerned with the amount of screen viewing their children engaged in, although the content of what was on the screen was of particular interest to them. Very few parents seemed to appreciate the linkage between preschoolers' screen-viewing habits and their potential risk for obesity.
Public health interventions are needed to increase parents' awareness with respect to the harmful effects of excessive screen viewing in preschoolers.
儿童肥胖已成为加拿大的一个公共卫生问题。有人认为,过多地观看屏幕(即电视、电脑、视频)是导致儿童肥胖风险增加的一个主要因素。探究幼儿在这种可改变行为方面的经历,可能有助于制定一个旨在初级预防肥胖的多方面计划。
了解家长对其学龄前儿童屏幕观看行为的看法和见解。
这项定性研究针对的是有2.5至5岁孩子的家长组成的异质样本。2003年9月至11月期间,两名经验丰富的主持人使用半结构化访谈指南主持了10个焦点小组。所有焦点小组都进行了录音,并逐字转录。2003年秋季至2004年春季,至少两名定性研究人员独立进行了归纳性内容分析。
许多家长并不关心孩子观看屏幕的时长,不过屏幕上的内容特别引起他们的兴趣。很少有家长似乎意识到学龄前儿童的屏幕观看习惯与其肥胖潜在风险之间的联系。
需要开展公共卫生干预措施,以提高家长对学龄前儿童过多观看屏幕的有害影响的认识。
