OBJECTIVES: To study the effect of a physical activitycounseling intervention on instrumental activity of dailyliving (IADL) disability.DESIGN: Primary care–based, single-blind, randomizedcontrolled trial.SETTING: City of Jyva¨skyla¨, central Finland.PARTICIPANTS: Six hundred thirty-two people aged 75to 81 who were able to walk 500 meters without assistance,were at most moderately physically active, had a Mini-Mental State Examination score greater than 21, had nomedical contraindications for physical activity, and gaveinformed consent for participation.INTERVENTION: A single individualized physical activitycounseling session with supportive phone calls from a physio-therapist every 4 months for 2 years and annual lectures onphysical activity. Control gr oup received no intervention.MEASUREMENTS: The outcome was IADL disabilitydefinedashavingdifficultiesinorinabilitytoperformIADLtasks.AnalyseswerecarriedoutaccordingtobaselineIADLdisability, mobility limitation, and cognitive status.RESULTS: At the end of the follow-up, IADL disabilityhad increased in both groups (Po.001) and was lower inthe intervention group, but the group-by-time interactioneffect did not reach statistical significance. Subgroupanalyses revealed that the intervention prevented incidentdisability in subjects without disability at baseline (riskratio50.68,95%confidenceinterval50.47–0.97)buthadno effect on recovery from disability.CONCLUSION: The physical activity counseling interven-tion had no effect on older sedentary community-dwellingpersons with a wide range of IADL disability, although itprevented incident IADL disability. The results warrantfurther investigation to explore the benefits of a primarycare–based physical activity counseling program on decreas-ing and postponing IADL disability.
