This study aimed to examine individual, behavioural and home environmental factors associated with frequency of consumption of fruit, vegetables and energy-dense snacks among adolescents. Adolescents aged 11-12 years (n = 521, 48% boys) completed a paper-based questionnaire during class-time which included a Food Frequency Questionnaire assessing their consumption of fruit, vegetables, and energy-dense (ED) snacks, and items assessing habits, self-efficacy, eating at the television (TV), eating with parents, parenting practices, and home availability and accessibility of foods. Multiple linear regression analyses showed that eating fruit and vegetables while watching TV and home availability and accessibility of fruit and vegetables were positively associated with frequency of fruit consumption and vegetable consumption, while home accessibility of ED snack foods was negatively associated with frequency of fruit consumption. Habit for eating ED snack foods in front the TV, eating ED snack foods while watching TV, and home availability of ED snacks were positively associated with frequency of ED snack consumption. This study has highlighted the importance of a healthy home environment for promoting fruit and vegetable intake in early adolescents and also suggests that, if snacking while TV viewing occurs, this could be a good opportunity for promoting fruit and vegetable intake. These findings are likely to be useful for supporting the development of multi-faceted interventions and aid us in knowing what advice to give to parents to help them to help their young adolescents to develop and maintain healthy eating habits.
本研究旨在探讨与青少年水果、蔬菜和高能量零食消费频率相关的个人、行为和家庭环境因素。11至12岁的青少年(n = 521,48%为男孩)在课堂上完成了一份纸质问卷,其中包括一份食物频率问卷,用于评估他们对水果、蔬菜和高能量(ED)零食的消费情况,以及评估习惯、自我效能、在电视前进食、与父母一起进食、育儿方式以及家庭食物供应和可及性的项目。多元线性回归分析表明,在看电视时食用水果和蔬菜以及家庭中水果和蔬菜的供应和可及性与水果消费频率和蔬菜消费频率呈正相关,而ED零食的家庭可及性与水果消费频率呈负相关。在电视前吃ED零食的习惯、看电视时吃ED零食以及家庭中ED零食的供应与ED零食消费频率呈正相关。本研究强调了健康家庭环境对促进青少年早期水果和蔬菜摄入量的重要性,还表明,如果在看电视时吃零食,这可能是促进水果和蔬菜摄入量的好机会。这些发现可能有助于支持多方面干预措施的制定,并帮助我们了解应向父母提供何种建议,以帮助他们的青少年养成并保持健康的饮食习惯。
