Behavioral Counseling Helps Employees Drop Pounds
A new pilot study demonstrates that worksite programs that couple dietary advice and behavioral counseling can help employees lose weight.
Researchers at Tufts University discovered that employees enrolled in the intervention arm of a randomized controlled trial lost on average, 18 pounds over a six-month period compared to a two-pound weight gain in a control group.
“Although previous research has focused on weight loss interventions based in office settings, those studies that we are aware of report modest weight loss over periods ranging from three months to two years.
“To the best of our knowledge, our approach is unique because of the inclusion of a strong behavioral component,” said Sai Krupa Das, Ph.D., a scientist in the Energy Metabolism Laboratory. “Over the course of the intervention, a counselor with training in both nutrition and behavior modification met at first weekly and later bi-weekly with the participants as a group during their lunch hour.
“In these sessions, discussions focused on strategies for menu planning, portion control and managing hunger, as well as dealing with stress-related and emotional eating. The participants also received individual support in a weekly e-mail exchange with the counselor.”
Researchers say the weight loss component of the study included men and women from four Boston area companies, all of whom had a body mass index (BMI) classifying them as overweight or obese.
Eighty-four (84) men and women from two of the companies, one for-profit and one non-profit, completed the intervention. Thirty-four (34) employees from the other two companies served as the control group.
For six months, the employees enrolled in the intervention followed a reduced calorie diet, emphasizing low-glycemic and high fiber foods that are less likely to raise blood sugar. The participants were responsible for purchasing and preparing their own food.
At the completion of the intervention, Das and colleagues observed substantial improvements in common markers for cardiovascular disease and diabetes risk. These included lower total cholesterol and glucose levels and lower blood pressure compared to the control group.
Additionally, the intervention participants were given the option to enroll in a six-month, structured maintenance program. No significant weight re-gain was observed in the 40 participants who enrolled and stayed in the program.
“Based on our results, it seemed the weight loss intervention became embedded in the office culture and also helped the weight of people who were not enrolled in the program,” said Susan B. Roberts, Ph.D., a co-author of the study and director of the Energy Metabolism Laboratory.
Rresearchers also made an effort to reach employees who were not involved by producing a series of newsletters and holding monthly seminars on general health-related topics such as cardiovascular health, childhood nutrition and exercise.
“To gauge the impact of this parallel programming, we asked employees in all four worksites who did not participate in the weight loss intervention to provide us with a self-report of their body weight and we saw an encouraging ripple effect,” added Roberts. “Overweight and obese employees at the intervention sites lost up to three pounds while employees at the control sites gained up to two pounds.”
Researchers said that future studies will include more worksites and longer post-intervention follow-up.
“For example, the current study does not explain why the employees at the non-profit intervention site lost significantly less weight than the employees at the for-profit site,” said Das. “It would be valuable to know what exactly about the culture fostered the success, because offices are really wonderful settings for weight loss groups. Co-workers have established relationships, creating an automatic support system and level of comfort.
“There is also the benefit of not having to set aside as much additional time for weight management. It can be built right into the work day. ”
