To assess the effectiveness of a primary care based programme of exercise on prescription among relatively inactive women over a two year period.
Randomised controlled trial.
17 primary care practices in Wellington, New Zealand.
1089 women aged 40-74 not undertaking 30 minutes of moderate intensity physical activity on at least five days of the week.
Brief physical activity intervention led by nurse with six month follow-up visit and monthly telephone support over nine months.
Physical activity assessed at baseline and 12 and 24 months. Secondary outcomes were quality of life (SF-36), weight, waist circumference,blood pressure, concentrations of fasting serum lipids,glycated haemoglobin (HbA1c), glucose, insulin, and physical fitness.
Mean age was 58.9 (SD 7) years. Trial retention rates were 93% and 89% at 12 and 24 months,respectively. At baseline,10%of intervention participants and 11% of control participants were achieving 150 minutes of at least moderate intensity physical activity a week. At 12 months rates increased to 43% and 30% and at 24 months to 39.3% and 32.8% (P<0.001), respectively. SF-36 physical functioning (P = 0.03) and mental health (P<0.05) scores improved more in intervention compared with control participants, but role physical scores were significantly lower (P<0.01). There were no significant differences in clinical outcomes. More falls (P<0.001) and injuries (P=0.03) were recorded in the intervention group.
This programme of exercise on prescription increased physical activity and quality of life over two years, although falls and injuries also increased. This finding supports the use of exercise on prescription programmes as part of population strategies to reduce physical inactivity.
评估一项基于初级保健的运动处方计划在两年时间里对相对不活跃女性的有效性。
随机对照试验。
新西兰惠灵顿的17家初级保健机构。
1089名年龄在40 - 74岁之间、每周至少五天未进行30分钟中等强度体育活动的女性。
由护士主导的简短体育活动干预，为期九个月，包括六个月的随访以及每月的电话支持。
在基线、12个月和24个月时评估体育活动情况。次要指标包括生活质量（SF - 36量表）、体重、腰围、血压、空腹血脂浓度、糖化血红蛋白（HbA1c）、血糖、胰岛素和体能。
平均年龄为58.9（标准差7）岁。在12个月和24个月时，试验保留率分别为93%和89%。基线时，干预组10%的参与者和对照组11%的参与者每周进行至少150分钟的中等强度体育活动。在12个月时，这一比例分别增至43%和30%，在24个月时分别增至39.3%和32.8%（P<0.001）。与对照组相比，干预组的SF - 36身体功能（P = 0.03）和心理健康（P<0.05）得分改善更为明显，但角色身体得分显著更低（P<0.01）。临床指标方面无显著差异。干预组记录到更多的跌倒（P<0.001）和受伤情况（P = 0.03）。
这项运动处方计划在两年内增加了体育活动和生活质量，尽管跌倒和受伤情况也有所增加。这一发现支持将运动处方计划作为减少身体不活动的人群策略的一部分。
