Objective.研究中年妇女5 ~ 7年后体力活动是否有助于身体健康功能。基线数据是在2000-2002年通过问卷调查收集的赫尔辛基市40-60岁的雇员。2007年在基线应答者中进行了随访调查（n = 7330，应答率83%）。在基线时询问过去12个月内休闲时间或通勤期间的身体活动。身体健康功能通过短表36问卷的身体成分总结（PCS）来测量。检查PCS平均评分，以及PCS评分差和好。剧烈运动和有条件锻炼的人比不运动和适度运动的人有更好的身体健康功能。基线健康和功能解释了发现的差异的主要部分。吸烟，饮酒和BMI进一步解释了一些差异。随访期间，身体健康功能平均评分无明显差异。身体健康状况良好，但调整后调节和不活动女性之间仍然存在一些差异。结论。身体活动和身体健康功能之间的前瞻性关联相对较弱，但高体力活动可能有助于保持良好的身体健康功能。剧烈活动可能比适度活动更有益。(C)2010年爱思唯尔公司All rights reserved.
Objective. To examine whether physical activity contributes to physical health functioning five to seven years later among middle-aged employees.Methods. Baseline data were collected in 2000-2002 by questionnaire surveys among 40-60-year-old employees of Helsinki City. A follow-up survey was conducted among baseline respondents in 2007 (n = 7330, response rate 83%). Physical activity during leisure time or commuting within the previous 12 months was asked at baseline. Physical health functioning was measured by physical component summary (PCS) of the Short-Form 36 questionnaire. PCS mean scores were examined, as were poor and good PCS scores.Results. Vigorously active and conditioning exercisers had better subsequent physical health functioning than did the inactive and moderately active. Baseline health and functioning explained a major part of the differences found. Smoking, alcohol use and BMI further explained some of the differences. No clear differences in physical health functioning mean scores emerged during follow-up. In good physical health functioning, however some differences between conditioning and inactive women remained after adjustments.Conclusions. Prospective associations between physical activity and physical health functioning were relatively weak, but high physical activity may help in maintaining good physical health functioning. Vigorous activity may be more beneficial than moderate activity. (C) 2010 Elsevier Inc. All rights reserved.
