To examine the effectiveness of a structured multimodal behavioral intervention to change dietary behaviors, as well as self-efficacy and social support for engaging in healthier diets.
A quasi-experimental design was used to assign sites into intervention and comparison groups. Data were collected at baseline, 3 months, and 6 months. The intervention group participated in Texercise Select, a 12-week lifestyle enhancement program. Multiple mixed-effects models were used to examine nutrition-related changes over time.
For the intervention group, significant improvements were observed for fast food consumption (P = .011), fruit/vegetable consumption (P = .008), water consumption (P = .009), and social support (P < .001) from baseline to 3 months. The magnitude of these improvements was significantly greater than changes in the comparison group.
Findings suggest the intervention's ability to improve diet-related outcomes among older adults; however, additional efforts are needed to maintain changes over longer periods.
研究一种结构化的多模式行为干预措施对改变饮食行为以及对参与更健康饮食的自我效能和社会支持的有效性。
采用准实验设计将研究地点分为干预组和对照组。在基线、3 个月和 6 个月时收集数据。干预组参与了 Texercise Select，这是一个为期 12 周的生活方式增强计划。采用多种混合效应模型来检测随时间的营养相关变化。
对于干预组，从基线到 3 个月时，快餐消费（P=0.011）、水果/蔬菜消费（P=0.008）、水消费（P=0.009）和社会支持（P<.001）都有显著改善。这些改善的幅度明显大于对照组的变化。
研究结果表明，该干预措施有能力改善老年人的饮食相关结果；然而，需要进一步努力来维持更长时间的变化。
