Abstract

OBJECTIVE

To explore postsecondary students' perspectives of the impacts of a mobile health (mHealth) food literacy intervention on dietary behaviors and why the intervention was or was not effective at influencing their dietary behavior.

DESIGN

Qualitative study using semistructured focus groups.

SETTING

Ontario, Canada.

PARTICIPANTS

Ten focus groups were conducted with postsecondary students (n = 30) aged 17-25 years from 2 universities.

PHENOMENON OF INTEREST

The impacts of a mHealth food literacy intervention on participants' dietary behaviors and why the intervention was or was not effective.

ANALYSIS

Focus group data were transcribed verbatim and analyzed using inductive thematic analysis.

RESULTS

Themes regarding dietary impacts included increased dietary consciousness, decrease in perceived unhealthy foods, increase in perceived healthy foods, making healthier dietary choices, and the Hawthorne effect. Intervention effectiveness themes encompassed barriers and facilitators to engagement and participants' ability to implement the intervention into their dietary behaviors. Facilitators included intervention suitability and application functionality; barriers included technology concerns, lacking time, food accessibility, food affordability, and intervention suitability.

CONCLUSION AND IMPLICATIONS

This study provides insights into the impact, facilitators, and barriers of a mHealth food literacy intervention on postsecondary students' dietary behaviors. Consideration of these facilitators and barriers may improve the effectiveness of future interventions.

摘要

目的

探讨高等院校学生对移动健康（mHealth）食品素养干预对饮食行为影响的看法，以及该干预对其饮食行为产生影响或未产生影响的原因。

设计

采用半结构化焦点小组的定性研究。

地点

加拿大安大略省。

参与者

对来自两所大学的17至25岁高等院校学生（n = 30）进行了10个焦点小组访谈。

研究关注的现象

mHealth食品素养干预对参与者饮食行为的影响，以及该干预有效或无效的原因。

分析

焦点小组数据逐字转录，并采用归纳主题分析法进行分析。

结果

有关饮食影响的主题包括饮食意识增强、对不健康食品的认知减少、对健康食品的认知增加、做出更健康的饮食选择以及霍桑效应。干预效果主题包括参与的障碍和促进因素，以及参与者将干预措施应用于其饮食行为的能力。促进因素包括干预的适用性和应用功能；障碍包括技术问题、时间不足、食品可及性、食品可负担性和干预的适用性。
