Objective: Recent national surveys have documented that the majority of adults in the United States do not meet the recommended levels of healthy lifestyle-related behaviors. The Nutrition and Physical Activity (NuPA) study was designed to promote fruit and vegetable consumption, physical activity, and weight management for a working population. Method: Data were collected nationwide, USA, from 2005 to 2007 and analyzed in 2008. A total of 2470 employed participants were randomized into the self-help (SH: n=1191) or self-help plus telephone counseling (SH + C: n=1279) group. The SH. +. C group received nine structured telephone counseling sessions in addition to the print materials. Results: A series of hierarchical regression analyses for each of the health behavior outcomes in the present-at-follow-up subsample (n=1098-1148) revealed that the SH. +. C was effective in increasing fruit and vegetable consumption. Among the overweight and obese participants, weight loss was significant in both the SH and SH. +. C groups. Conclusion: Using a theory-based behavioral change counseling technique and targeting multiple health behaviors among employed individuals, our findings demonstrate that the addition of telephone counseling to mailed self-help materials is effective in promoting healthy diet and weight management.
