To compare the effects of a physical activity (PA) intervention of group meetings versus group meetings supplemented by personal calls or automated calls on the adoption and maintenance of PA and on weight stability among African-American women.
Randomized clinical trial with three conditions randomly assigned across six sites.
Health settings in predominately African-American communities.
There were 288 women, aged 40 to 65, without major signs/symptoms of pulmonary/cardiovascular disease.
Six group meetings delivered over 48 weeks with either 11 personal motivational calls, 11 automated motivational messages, or no calls between meetings.
Measures included PA (questionnaires, accelerometer, aerobic fitness), weight, and body composition at baseline, 24 weeks, and 48 weeks.
Analysis of variance and mixed models.
Retention was 90% at 48 weeks. Adherence to PA increased significantly (p < .001) for questionnaire (d = .56, 128 min/wk), accelerometer (d = .37, 830 steps/d), and aerobic fitness (d = .41, 7 steps/2 min) at 24 weeks and was maintained at 48 weeks (p < .001), with no differences across conditions. Weight and body composition showed no significant changes over the course of the study.
Group meetings are a powerful intervention for increasing PA and preventing weight gain and may not need to be supplemented with telephone calls, which add costs and complexity.
比较小组会议形式的体育活动（PA）干预与补充了个人电话或自动电话的小组会议干预对非裔美国女性体育活动的采用和维持以及体重稳定性的影响。
在六个地点随机分配三种条件的随机临床试验。
主要为非裔美国人社区的健康场所。
288名年龄在40至65岁之间、无肺部/心血管疾病主要体征/症状的女性。
在48周内进行六次小组会议，会议期间分别有11次个人激励电话、11次自动激励信息或无电话。
测量指标包括基线、24周和48周时的体育活动（问卷调查、加速度计、有氧适能）、体重和身体成分。
方差分析和混合模型。
48周时的保留率为90%。24周时，问卷调查（d = 0.56，每周128分钟）、加速度计（d = 0.37，每天830步）和有氧适能（d = 0.41，每2分钟7步）的体育活动依从性显著增加（p < 0.001），并在48周时保持（p < 0.001），各条件之间无差异。在研究过程中，体重和身体成分无显著变化。
小组会议是增加体育活动和预防体重增加的有效干预措施，可能无需补充电话，因为电话会增加成本和复杂性。
