Physical activity (PA) is a cornerstone in the management of type 2 diabetes (T2DM). This pilot investigation explores the effects of a standard diabetes education program compared with a supplemental PA intervention on diabetes-related health outcomes.
Using a prospective 2-armed design, 96 adults with T2DM were randomly assigned to either standard care (diabetes education program; n = 49) or standard care supplemented with an 8-week, individualized-counseling and community-based PA component (n = 47). Measurements were taken at baseline, 3, 6, and 12 months. Primary outcomes were changes in PA (self-report) and HbA1c. Between group changes were compared using analysis of covariance (ANCOVA) and changes over time using repeated-measures ANOVA.
In comparison with standard care, the supplemental group demonstrated an increase in PA (Ps < 0.01) and cardiorespiratory fitness (Ps < 0.05) from baseline to all follow-up time-points. HbA1c levels declined (P < .05) from baseline to all time points in the standard care group. Reduction in cholesterol-ratio (P < .01), increase in HDL (P < .05), and reductions in blood pressure, resting heart rate and BMI (approaching statistical significance Ps < 0.10) were also reported for both groups.
PA counseling in addition to standard care is effective for promoting PA behavior change and positive health-related outcomes among individuals with T2DM.
身体活动（PA）是 2 型糖尿病（T2DM）管理的基石。本初步研究探讨了标准糖尿病教育计划与补充 PA 干预对糖尿病相关健康结果的影响。
使用前瞻性 2 臂设计，96 名 T2DM 成年人被随机分配到标准护理（糖尿病教育计划；n = 49）或标准护理加 8 周个体化咨询和基于社区的 PA 成分（n = 47）。在基线、3、6 和 12 个月时进行测量。主要结果是 PA（自我报告）和 HbA1c 的变化。使用协方差分析（ANCOVA）比较组间变化，使用重复测量方差分析比较随时间的变化。
与标准护理相比，补充组从基线到所有随访时间点的 PA（P < 0.01）和心肺适能（P < 0.05）均增加。标准护理组的 HbA1c 水平从基线到所有时间点均下降（P < 0.05）。两组均报告胆固醇比值降低（P < 0.01）、HDL 升高（P < 0.05）以及血压、静息心率和 BMI 降低（接近统计学意义 P < 0.10）。
除标准护理外，PA 咨询对于促进 T2DM 个体的 PA 行为改变和积极的健康相关结果是有效的。
