To determine whether Hispanic residents receiving the Healthy Fit intervention enhanced with Motivational Interviewing (MI) experienced greater improvements in body composition, relative to participants receiving the initial intervention.
Quasi-experimental evaluation.
El Paso, Texas.
Among 656 baseline participants, 374 (54%) completed the 12-month assessment.
In Healthy Fit, community health workers (CHWs) promote nutrition and exercise. To strengthen intrinsic motivation and help participants overcome barriers to change, we incorporated a 30-minute motivational interview into the baseline assessment. Follow-up phone calls at 1, 3, and 6 months were identical across conditions.
CHWs assessed body mass index (BMI) and body fat percentage (BFP) using a bioelectrical impedance scale.
Regression models estimated differences between intervention conditions on change in BMI and BFP from baseline to the 12-month assessment.
Participants receiving MI had 2.13 times higher odds of losing weight (OR = 2.14, 95% CI [1.30, 3.53], P = .003) and 2.59 times higher odds of reduced BFP (OR = 2.59, 95% CI [1.51, 4.41], P < .001), relative to initial intervention participants. MI participants lost an average of 1.23 kg (2.71 lbs.) and their BFP declined 2% over 12 months.
Findings suggest CHW use of MI is a promising approach for promoting incremental changes in diet and exercise, which Healthy Fit integrates into a low-cost intervention.
确定接受健康适应强化激励访谈（MI）干预的西班牙裔居民在身体成分方面是否比接受初始干预的参与者有更大的改善。
准实验评估。
德克萨斯州埃尔帕索。
在 656 名基线参与者中，有 374 名（54%）完成了 12 个月的评估。
在健康适应中，社区卫生工作者（CHW）促进营养和运动。为了增强内在动机并帮助参与者克服改变的障碍，我们在基线评估中纳入了 30 分钟的激励访谈。在 1、3 和 6 个月的随访电话在两种情况下是相同的。
CHW 使用生物电阻抗秤评估体重指数（BMI）和体脂肪百分比（BFP）。
回归模型估计干预条件之间从基线到 12 个月评估的 BMI 和 BFP 变化的差异。
接受 MI 的参与者减肥的可能性高出 2.13 倍（OR = 2.14，95%CI [1.30，3.53]，P =.003），体脂肪百分比降低的可能性高出 2.59 倍（OR = 2.59，95%CI [1.51，4.41]，P <.001），与初始干预参与者相比。MI 参与者在 12 个月内平均减轻 1.23 公斤（2.71 磅），体脂肪百分比下降 2%。
研究结果表明，CHW 使用 MI 是促进饮食和运动渐进式改变的一种有前途的方法，健康适应将其整合到低成本干预中。
