Context The increase in sedentary lifestyle may contribute to the rise in o
besity nationally. Although guidelines suggest that physicians counsel all
patients about exercise, physicians counsel only a minority of their patien
ts. Whether patient factors influence physician counseling is not well esta
blished.
Objectives To examine and to identify factors associated with exercise coun
seling by US physicians.
Design and Setting National population-based supplemental (Year 2000) surve
y to the 1995 National Health Interview Survey.
Participants Of the 17 317 respondents to the Year 2000 supplemental survey
, 9711 adults had seen a physician in the previous year, and 9299 responded
when asked about physician counseling on exercise.
Main Outcome Measure Physician counseling to begin or to continue to exerci
se.
Results Of 9299 respondents, 34% reported being counseled about exercise at
their last visit. After adjustment for other sociodemographic and clinical
factors, women were slightly more likely to be counseled, with an adjusted
odds ratio (AOR) of 1.15 (95% confidence interval [CI], 1.02-1.29). Physic
ians counseled older patients (>30 years) more often than younger patients;
those aged 40 to 49 years were counseled most often (AOR, 1.71 [95% CI, 1.
34-2.20]). Patients with incomes above $50 000, those with higher levels of
physical activity, college graduates, and patients who were overweight to
obese (body mass index: 25 to greater than or equal to 30 kg/m(2)) were mor
e likely to be counseled, as were patients with cardiac disease (AOR, 1.81
[95% CI, 1.52-2.14]) and diabetes (AOR, 1.87 [95% CI, 1.46-2.38]), Counseli
ng did not vary by physician specialty or patient race.
Conclusion The rate of physician counseling about exercise is low nationall
y. Physicians appear to counsel as secondary prevention and are less likely
to counsel patients at risk for obesity. The failure to counsel younger, d
isease-free adults and those from lower socioeconomic groups may represent
important missed opportunities for primary prevention.
