Adolescence represents a critical transition phase during which individuals acquire eating behaviours that can track into adulthood. This study aims to characterise trends in eating behaviours throughout adolescence by investigating the presence of sub-groups of individuals presenting distinct trajectories of vegetable and fruit, sugary beverage, breakfast and fast-food consumption. Data from 744 MATCH study Canadian participants followed from 11 to 18 Years old (2013-2019) were included in the analyses. Participants reported how often they ate breakfast and consumed vegetables and fruits, sugary beverages and fast foods. Trajectories of eating behaviours over seven years were identified using group-based multi-trajectory modelling. For girls, three different groups were identified, namely 'stable food intake with a decline in daily breakfast consumption' (39.9%), 'moderate food intake and worsening in overall eating behaviours' (38.0%) and 'stable high food intake' (22.1%). For boys, five different groups were identified, namely 'low food intake with stable daily breakfast consumption' (27.3%), 'breakfast-skippers and increasing fast food intake' (27.1%), 'low food intake with a decline in daily breakfast consumption' (23.9%), 'high food intake with worsening of eating behaviours' (13.3%) and 'average food intake with consistently high breakfast consumption' (8.4%). Eating behaviours evolve through various distinct trajectories and sub-group-specific strategies may be required to promote healthy eating behaviours among adolescents.
青春期是一个关键的过渡阶段，在此期间，个体形成的饮食习惯可能会延续到成年。本研究旨在通过调查个体在蔬菜和水果、含糖饮料、早餐和快餐消费方面存在不同轨迹的亚组的存在情况，来描述青春期饮食行为的变化趋势。分析中纳入了 744 名 MATCH 研究加拿大参与者的数据，这些参与者从 11 岁到 18 岁（2013-2019 年）进行了随访。参与者报告了他们吃早餐的频率以及食用蔬菜和水果、含糖饮料和快餐的频率。使用基于群组的多轨迹建模来确定七年期间饮食行为的轨迹。对于女孩，确定了三个不同的群组，即“稳定的食物摄入量，每日早餐摄入量下降”（39.9%）、“适度的食物摄入量，整体饮食行为恶化”（38.0%）和“稳定的高食物摄入量”（22.1%）。对于男孩，确定了五个不同的群组，即“低食物摄入量，稳定的每日早餐摄入量”（27.3%）、“不吃早餐，快餐摄入量增加”（27.1%）、“低食物摄入量，每日早餐摄入量下降”（23.9%）、“高食物摄入量，饮食行为恶化”（13.3%）和“平均食物摄入量，始终保持高早餐摄入量”（8.4%）。饮食行为通过各种不同的轨迹演变，可能需要针对特定亚组的策略来促进青少年的健康饮食行为。
