Patient use of weight-management activities: A comparison of patient and physician assessments

ObjectiveExamine concordance between patient and physician assessments of patient self-reported use of weight-management activities.MethodsAnalysis of baseline data from a randomized controlled trial of patient and physician interventions to improve patient–physician communication (41 physicians and 274 of their patients).ResultsA majority of patients reported regular exercise (55.6%) and efforts to lose weight, such as eating less (63.1%) while physicians only perceived one-third of patients as engaging in those activities (exercise, 36.6%; weight loss, 33.3%). Kappa scores indicated small agreement between patient and physician assessments of patient self-reported use of exercise, mean kappa 0.28 (range 0.15 to 0.40) and no agreement between patient and physician assessments of patient self-reported efforts to lose weight, mean kappa −0.14 (range −0.26 to −0.01). Obese patients were more likely than non-obese patients to report trying to lose weight or exercising regularly (p < 0.05), but physicians were less likely to perceive obese patients as engaging in those activities (p < 0.05).ConclusionsPrimary care physicians differed considerably from their patients, especially obese patients, in their assessments of patient use of weight-management activities.Practice implicationsThese results highlight the importance of improving patient–provider communication about weight-management activities, particularly among obese patients.
