Background.Lifestyle intervention programs after bariatric surgery have been suggested to maximise health outcomes. This pilot study aimed to investigate the feasibility and impact of an 8-week combined supervised exercise with nutritional-behavioral intervention following Roux-en-Y gastric bypass and sleeve gastrectomy.Methods.Eight female patients (44 ± 8 years old, BMI = 38.5 ± 7.2 kgm−2) completed the program. Before and after intervention, anthropometric measures, six-minute walk test (6MWT), physical activity level, eating behavior, and quality of life (QoL) were assessed. Percentage weight loss (%WL) outcomes were compared with a historical matched control group.Results.The program significantly improved functional capacity (mean increment in 6MWT was 127 ± 107 meters,p=0.043), increased strenuous intensity exercise (44 ± 49 min/week,p=0.043), increased consumption of fruits and vegetables (p=0.034), reduced consumption of ready meals (p=0.034), and improved “Change in Health” in QoL domain (p=0.039). The intervention group exhibited greater %WL in the 3–12-month postsurgery period compared to historical controls, 12.2 ± 7.5% versus 5.1 ± 5.4%, respectively (p=0.027).Conclusions.Lifestyle intervention program following bariatric surgery is feasible and resulted in several beneficial outcomes. A large randomised control trial is now warranted.

To investigate longitudinal and bidirectional associations between mental health and physical activity from midlife into old age.Analysis was based on data from 6909 participants (aged 45 to 69 in 1997/99) from the Whitehall II cohort in the UK. Latent growth curve analysis examined possible bidirectional associations between the SF-36 Mental Component Summary and weekly physical activity measured at three time-points over ten years.Mental health and physical activity were associated at baseline (β=0.17, 95% CI 0.13, 0.21) and associations persisted into old age. In the latent growth curve model, both mental health and physical activity increased and their rates of change 'moved together' over time (β=0.24, 95% CI 0.11, 0.37). Relatively high baseline levels of either variable were associated with slightly slower increases in the other outcome (β=-0.02, 95% CI -0.03, -0.01; β=-0.07, 95% CI -0.11, -0.13), which are thought to reflect regression to the mean. However, those who started high on either variable remained the most advantaged at end of follow-up.From midlife to old age, greater physical activity is associated with better mental health and vice versa. These findings suggest persistent longitudinal and bidirectional associations between physical activity and mental health.
