Comparing Weight Loss–Maintenance Outcomes of a Worksite-Based Lifestyle Program Delivered via DVD and Face-to-Face: A Randomized Trial

Background. Native Hawaiians and other Pacific Islanders have high rates of overweight and obesity compared with other ethnic groups in Hawai‘i. Effective weight loss and weight loss–maintenance programs are needed to address obesity and obesity-related health inequities for this group. Aims. Compare the effectiveness of a 9-month, worksite-based, weight loss–maintenance intervention delivered via DVD versus face-to-face in continued weight reduction and weight loss maintenance beyond the initial weight loss phase. Method. We tested DVD versus face-to-face delivery of the PILI@Work Program’s 9-month, weight loss–maintenance phase in Native Hawaiian–serving organizations. After completing the 3-month weight loss phase, participants ( n = 217) were randomized to receive the weight loss–maintenance phase delivered via trained peer facilitators or DVDs. Participant assessments at randomization and postintervention included weight, height, blood pressure, physical functioning, exercise frequency, and fat intake. Results. Eighty-three face-to-face participants were retained at 12 months (74.1%) compared with 73 DVD participants (69.5%). There was no significant difference between groups in weight loss or weight loss maintenance. The number of lessons attended in Phase 1 of the intervention (β = 0.358, p = .022) and baseline systolic blood pressure (β = −0.038, p = .048) predicted percent weight loss at 12 months. Discussion and Conclusion. Weight loss maintenance was similar across groups. This suggests that low-cost delivery methods for worksite-based interventions targeting at-risk populations can help address obesity and obesity-related disparities. Additionally, attendance during the weight loss phase and lower baseline systolic blood pressure predicted greater percent weight loss during the weight loss–maintenance phase, suggesting that early engagement and initial physical functioning improve long-term weight loss outcomes.

Secondary Outcomes

Introduction: Workplace wellness programs offer opportunities for decreasing obesity in adults. The effectiveness of such programs varies and is influenced by key intervention components (e.g. duration, intensity, content). We developed a multicomponent workplace wellness program, MyWay to Health (MW2H), which was adapted from an evidence-based weight loss intervention with demonstrated efficacy and meets the 2013 Guideline for the Management of Overweight and Obesity in adults. The purpose of this one-group pretest-posttest study was to evaluate program acceptability and effectiveness of MW2H on primary and secondary outcomes. Hypotheses: We hypothesized that MW2H would result in 1) clinically meaningful weight loss of ≥5%, and 2) improvements in cardiometabolic indices. Methods: During weeks 1-26, participants met privately with an interventionist for up to 24 weekly, 40-minute sessions, receiving training in eating and physical activity behavior change, self-regulation, and socioenvironmental strategies. During weeks 27-52, participants received maintenance support through phone calls, email, or in-person visits. Our primary outcome was percent weight loss. Secondary outcomes included improvement in BMI, waist circumference, HbA1c, cholesterol, and blood pressure. Outcomes were compared at baseline and 26 weeks; body weight only was measured at 52 weeks. Wilcoxin Signed Rank Tests were used to examine outcomes. Results: Participants (N=154) were mostly female (85%), White (75%), had a median age of 50 (Interquartile Range (IQR): 17) years, a median baseline BMI of 34.7 (IQR: 8.8), a median household income of $70,000 (IQR: $50,000), and 54% had a college degree or higher. Median number of in-person sessions attended was 19 (IQR: 4.0). Percent weight loss at 26 weeks (median [IQR]: 7.5% [6.8%]) was clinically meaningful, with 71% of participants achieving ≥5% weight loss. Statistically significant improvements in BMI, waist circumference, HbA1c, HDL cholesterol, and systolic and diastolic blood pressure (p<0.001 for all) were observed. At week 52, body weight data were available for 106 (69%) participants. Median percent weight loss from baseline was 7.0% (IQR: 9.3%). Of participants who achieved ≥5% weight loss at week 26, 94% maintained this level of weight loss at week 52. Conclusions: The MW2H workplace wellness program was acceptable to participants, evidenced by high program attendance, and resulted in clinically meaningful and statistically significant improvements in body weight and cardiometabolic indices. A majority of participants achieved ≥5% weight loss by 26 weeks, and nearly all participants for whom data was available maintained this level of weight loss at week 52. Additional research is needed to optimize intervention components, identify factors that contribute to weight maintenance, and examine MW2H effectiveness in a more diverse population.

Positive Effect

In this secondary analysis of the DiOGenes study, we investigated whether physical activity (PA) contributes to diet-induced weight loss and helps to reduce subsequent regain. We also studied the associations of PA with changes in cardiometabolic variables. Adults with overweight were included and followed an 8-week low-calorie diet (LCD). When successful (>8% weight loss), participants were randomized to different ad libitum diet groups and were advised to maintain their weight loss over the 6-month intervention period. Body weight (BW), body composition, cardiometabolic variables and subjectively-assessed PA were measured at baseline, at the end of weight loss and at the end of the intervention. BW was reduced by the LCD (from 99.8 ± 16.7 to 88.4 ± 14.9 kg; P < 0.001). This reduction was maintained during the weight maintenance period (89.2 ± 16.0 kg). Total PA (sum score of the three subscales of the Baecke questionnaire) increased during the weight loss period (from 8.16 ± 0.83 to 8.39 ± 0.78; P < 0.001) and this increase was subsequently maintained (8.42 ± 0.90). We found no evidence that baseline PA predicted weight loss. However, a higher level of baseline PA predicted a larger weight-loss-induced improvement in total cholesterol, triglycerides, glucose and CRP, and in post-prandial insulin sensitivity (Matsuda index). Subsequent weight and fat mass maintenance were predicted by the post-weight loss level of PA and associated with changes in PA during the weight maintenance phase. In conclusion, despite the fact that higher baseline levels of PA did not predict more weight loss during the LCD, nor that an increase in PA during the LCD was associated with more weight loss, higher PA levels were associated with more improvements in several cardiometabolic variables. The positive effect of higher PA on weight loss maintenance seems in contrast to randomized controlled trials that have not been able to confirm a positive effect of exercise training programmes on weight loss maintenance. This analysis supports the notion that higher self-imposed levels of PA may improve the cardiometabolic risk profile during weight loss and help to maintain weight loss afterwards.

Meal Replacements

Background and aims: Meal replacement diets consist of replacing one or more meals with an artificial nutritional supplement. The objective of this study was to compare the effect of one against two meal replacement strategies on body composition and cardiovascular risk parameters in patients with obesity. Methods: A randomized clinical trial was designed with a modified hypocaloric diet with an artificial nutritional preparation replacing one or two meals for three months in patients with obesity and osteoarthritis pending orthopedic surgery. An anthropometric evaluation and a measurement of the body composition were done with bioelectrical impedance measurement at the beginning and at three months. Results: A total of 112 patients were recruited. Fifty-two patients (46.4%) were randomized to one replacement and 60 patients (53.6%) to two meal replacements. Eighty-one patients (72.3%) were women, and the average age was 61 (11.03) years. The percentage of weight loss at three months was 8.27 (4.79)% (one meal replacement: 7.98 (5.97)%; two meal replacements: 8.50 (3.48)%; p = 0.56). A decrease in fat mass measured by the fat mass index (FMI) was detected (one meal replacement: −2.15 (1.45) kg/m2 vs. two meal replacements: −2.78 (2.55) kg/m2; p > 0.05), and a relative increase in fat-free mass was observed (one meal replacement: +3.57 (4.61)% vs. two meal replacements: +2.14 (4.45)%; p > 0.05). A decrease in HOMA-IR, systolic blood pressure (SBP), and total cholesterol was observed in both groups without differences between them. Conclusions: The substitution strategies of one or two meal replacements were effective in weight loss and fat mass decrease without differences between the two groups. An improvement in lipid parameters, glycemic control, and systolic blood pressure was observed without differences between strategies.
