Impact of a telephone-based intervention on the reduction of health risks.
OBJECTIVE
Evaluate the long-term impact of telephone-based interventions that target high risk, ready-to-change individuals.


METHODS
Quasi-experimental design with pre/post comparisons of lifestyle-related health risks between participants and nonparticipants.


METHODS
Six organizations from the private and public sectors.


METHODS
Subjects were 607 intervention participants who were compared with a control group of 1134 eligible nonparticipants.


METHODS
Health risk assessment at baseline and at an average of 2 years later measured risk in 13 lifestyle areas.


METHODS
Programs were offered in seven areas: back care, cholesterol control, eating habits, exercise and activities, stress management, tobacco use, and weight control. Each program was conducted by a trained health educator who provided information and counseling to facilitate change in the area selected by the participant. All counseling was done by telephone and included three to five contacts over a 1-year period.


RESULTS
Binary logistic regression models controlling for gender and age revealed both specific and general effects. Participants were 1.8 to 3.5 times as likely as nonparticipants to reduce the targeted risk in six of seven risk areas. In addition, participants were 1.7 to 3.5 times as likely as nonparticipants to reduce their risks in nine of 13 areas not targeted by the intervention (i.e., general effect). Overall, participants significantly reduced their number of risks, whereas nonparticipants significantly increased their risk (difference of .85 risks).


CONCLUSIONS
Results show that at-risk participants make long-term improvements in health risks directly related to the intervention in which they participate. Results also suggest that this intervention may help individuals develop behavior-change skills they can apply to other lifestyle issues.
