背景以患者为中心的运动加营养评估和咨询（PACE+）是一种基于初级保健环境的干预措施，旨在帮助患者改变体力活动和饮食行为。在4个月的干预前后，对173名成年人进行了评估。所有患者都完成了计算机化评估，并制定了量身定制的“行动计划”，以改变一种体力活动和一种营养行为，然后与他们的提供者讨论。访问后，受试者被随机分配到四个扩展干预条件之一：对照，仅邮件，不频繁的电话和邮件，以及频繁的电话和邮件。在基线和4个月时收集五种目标行为的自我报告（中度和剧烈体力活动阶段的变化、膳食脂肪、水果/蔬菜摄入量和暴饮暴食行为）。还采取了可接受性措施。所有条件下的参与者随着时间的推移改善了所有行为，支持计算机和提供者咨询组件的实用性。扩展干预没有产生关于模式（电话或邮件）或强度（频繁或不频繁）的差异结果。然而，对于每一种行为，以改变行为为目标的参与者比那些没有以改变行为为目标的参与者进步更大。干预的可接受性很高。以初级保健为基础的互动式健康交流，以改善身体活动和饮食行为是可行的，并取得了可喜的初步成果。(C)2001年美国健康基金会和爱思唯尔科学（美国）。
Background. Patient-centered Assessment and Counseling on Exercise plus nutrition (PACE+) is an intervention based in primary care settings to help patients change physical activity and dietary behaviors.Methods. One hundred seventy-three adults were assessed before and after a 4-month intervention. All patients completed a computerized assessment and created tailored "action plans" to change one physical activity and one nutrition behavior that they then discussed with their provider. After the visit, subjects were randomized to one of four extended intervention conditions: control, mail only, infrequent phone and mail, and frequent phone and mail. Self-report of five target behaviors (moderate and vigorous physical activity stage of change, dietary fat, fruit/vegetable intake, and overeating behaviors) was collected at baseline and 4 months. Acceptability measures were also taken.Results. Participants in all conditions improved on all behaviors over time, supporting the utility of the computer and provider counseling components. The extended intervention did not produce differential results with respect to mode (phone or mail) or intensity (frequent or infrequent). However, for each behavior, participants who targeted the behavior to change improved significantly more than those who did not target the behavior. Acceptability of the intervention was high.Conclusions. Primary care-based, interactive health communication to improve physical activity and dietary behavior is feasible and has promising initial results.
