Abstract Body (Do not enter title and authors here): Objective: Men who work in trade and labor occupations experience high rates of obesity and related cardiovascular disease due to high rates of sedentary leisure time and poor diet. Despite this, they are underrepresented in weight control programs. This pilot randomized trial evaluated the feasibility and acceptability of a 6-month program tailored to this occupational group versus a non-tailored standard-of-care behavioral weight loss program.

Methods: Men with overweight or obesity working in trade and labor occupations were randomly assigned to either a tailored program or the DPP Group Lifestyle Balance program delivered via 16 one-hour virtual group sessions. In-person assessments were conducted at baseline, 3, and 6 months. Semi-structured interviews and self-report were used to assess the acceptability of the interventions. Feasibility was assessed using recruitment metrics and proportion group sessions and study assessments completed.

Results: Participants (N = 28; median 44.0 years, interquartile range (IQR): 38.5-54.5), median 31.8 BMI, IQR 31.1-39.6) were recruited into the study over 7 months, and 71% and 79% were retained for assessments at 3 and 6 months, respectively. Overall, participants attended a median of 7 of the 16 group sessions (IQR 2.5-11.5). The tailored group completed a median of 11 of 16 weekly online progress reports (IQR 5-15). All participants reported that they would recommend the programs to other men and felt confident that they would continue using the strategies learned in the programs. Though the trial focused on feasibility rather than efficacy, median weight losses at 6 months were -3.0% in the tailored group (95% CI -9.3, -0.6) and -1.9% in the standard group (95% CI -7.4, 2.0).

Conclusions: Results suggest that both the tailored and standard weight loss interventions were well received by this group, but engagement was low. Future research should focus on understanding how to increase engagement rather than exclusively tailoring the program to this occupational group to enhance this group's involvement with cardiovascular disease prevention programs.
