This study examined, in a group of older patients, (a) the effectiveness of an invitation to participate in a program providing individualized physical activity advice in a primary care setting and (b) the changes in self-reported physical activity and symptoms in patients with osteoarthritis (OA).
Healthy, sedentary community-dwelling men and women aged 60 years or more were invited to participate. Following random allocation, the intervention group received individualized physical activity advice at baseline and at 3, 6, and 12 months followup.
Of the 299 people who satisfied the study's inclusion criteria, a subgroup of 69 people reported pain and stiffness of the hip or knee at baseline. These patients reported increases in frequency and time of walking and vigorous exercise (all P < 0.001), with no change to OA symptom scores (pain and stiffness), and a small decline in physical functioning was reported at 12 months followup in the control group only (P = 0.027). At the 12-month followup more intervention participants than control participants (P = 0.013) reported a greater intention to exercise.
An offer of primary care-based physical activity advice, with an emphasis on the benefits for general health (rather than "treatment" for OA), will attract individuals with OA symptoms. Although the present study was unable to demonstrate intervention-control group differences for the majority of outcomes, intention to exercise did appear to be positively influenced.
本研究在一组老年患者中考察了：（a）在初级保健机构中邀请患者参与提供个性化体育活动建议项目的有效性；（b）骨关节炎（OA）患者自我报告的体育活动及症状的变化。
邀请60岁及以上健康的、久坐不动的社区居民男女参与。随机分配后，干预组在基线时以及随访的3个月、6个月和12个月时接受个性化体育活动建议。
在满足研究纳入标准的299人中，有69人在基线时报告有髋部或膝部疼痛和僵硬。这些患者报告步行和剧烈运动的频率及时间增加（所有P<0.001），OA症状评分（疼痛和僵硬）无变化，仅在对照组的12个月随访时报告身体功能有小幅下降（P=0.027）。在12个月随访时，报告有更强运动意愿的干预组参与者多于对照组参与者（P=0.013）。
提供基于初级保健的体育活动建议，强调对总体健康的益处（而非对OA的“治疗”），将吸引有OA症状的个体。尽管本研究未能证明干预组与对照组在大多数结果上存在差异，但运动意愿似乎确实受到了积极影响。
