Determine the effectiveness and acceptability of a text message intervention (DTEXT) on HbA1c and self-management behaviors for Australian adults with type 2 diabetes.
Using intention to treat analysis and generalized estimating equations, this randomized controlled trial of 395 adults determined change in HbA1c at 3 and 6 months between the intervention and control group. Secondary outcomes included change in nutrition, physical activity, blood lipid profile, body mass index, quality of life, self-efficacy, medication taking and program acceptability.
No significant difference was observed between the intervention or control group for HbA1c at 3 months (P = 0.23) or 6 months (P = 0.22). Significant improvements were seen in consumption of vegetables at 3 months (P < 0.001) and 6 months (P = 0.04); fruit at 3 months (P = 0.046) and discretionary sweet foods at 3 months (P = 0.02). No other significant effects seen. The intervention demonstrated high rates of acceptability (94.0%) and minimal withdrawal (1.5%).
DTEXT was an acceptable text message intervention that improved some nutritional behaviors in people with type 2 diabetes, but did not significantly improve HbA1c or other outcomes. Further research is required to optimize DTEXT.
DTEXT provides an acceptable, feasible form of self-management support that may complement existing diabetes care.
评估针对澳大利亚 2 型糖尿病患者的短信干预（DTEXT）对糖化血红蛋白（HbA1c）和自我管理行为的有效性和可接受性。
本随机对照试验纳入 395 名成年人，采用意向治疗分析和广义估计方程，比较干预组和对照组在 3 个月和 6 个月时 HbA1c 的变化。次要结局包括营养、体力活动、血脂谱、体重指数、生活质量、自我效能、药物治疗和方案可接受性的变化。
干预组和对照组在 3 个月（P = 0.23）或 6 个月（P = 0.22）时的 HbA1c 无显著差异。3 个月（P < 0.001）和 6 个月（P = 0.04）时蔬菜摄入量、3 个月（P = 0.046）和 3 个月（P = 0.02）时水果摄入量和 3 个月时可自由支配甜食摄入量显著增加。未观察到其他显著效果。该干预措施具有较高的可接受性（94.0%）和极低的退出率（1.5%）。
DTEXT 是一种可接受的短信干预措施，可改善 2 型糖尿病患者的一些营养行为，但不能显著改善 HbA1c 或其他结局。需要进一步研究来优化 DTEXT。
DTEXT 提供了一种可接受且可行的自我管理支持形式，可补充现有的糖尿病护理。
