Abstract

The eating habits of adolescents are often inadequate, with high consumption of unhealthy foods and low consumption of healthy foods. It is necessary to design and implement effective interventions to improve eating habits at this age and evaluate their feasibility, acceptability, and effectiveness. The use of theories for behavior change in health interventions favors the adoption of healthy behaviors. Due to this, the objective was set to determine the feasibility, acceptability, and effect on food consumption of a new educational nutritional intervention program for adolescents based on the Social Cognitive Theory (SCT) and supported by the Trans-theoretical Model (TTM) and identify areas of improvement in study design and intervention for future larger-scale studies. A pilot study of a cluster randomized controlled trial was conducted in adolescents of both sexes, 12 to 15 years of age, students from a public secondary school in Tonala, Jalisco, Mexico. The results show that a nutritional education intervention for adolescents, based on SCT and supported by the TTM, is feasible, acceptable, and with positive results in the modification of the consumption of ultra-processed foods, vegetables/fruits, and water. This pilot study identified some aspects that could be improved to enhance the effectiveness of the interventions in future studies.

基于社会认知理论的青少年教育营养干预计划:集群随机对照试验的试点研究。
青少年的饮食习惯往往不够好,不健康食品吃得多,健康食品吃得少。有必要设计和实施有效的干预措施来改善这个年龄段的饮食习惯,并评估其可行性、可接受性和有效性。在健康干预中使用行为改变理论有利于采纳健康行为。因此,我们的目标是确定一项基于社会认知理论(Social Cognitive Theory,SCT)并得到跨理论模型(Trans-theoretical Model,TTM)支持的新的青少年营养教育干预计划的可行性、可接受性和对食物消费的影响,并为未来更大规模的研究确定在研究设计和干预方面需要改进的地方。在墨西哥哈利斯科州托纳拉一所公立中学的 12 至 15 岁男女青少年中开展了一项分组随机对照试验的试点研究。结果表明,基于 SCT 并得到 TTM 支持的青少年营养教育干预是可行的、可接受的,并在改变超加工食品、蔬菜/水果和水的消费方面取得了积极成果。这项试点研究发现了一些可以改进的方面,以便在今后的研究中提高干预措施的效果。
