BACKGROUNDThis systematic review and meta-analysis evaluates the additional effects of exercise to hypocaloric diet on body weight, body composition, glycaemic control, and cardio-respiratory fitness in adults with overweight or obesity and type 2 diabetes.METHODSEmbase, Medline, Web of Science, and Cochrane Central databases were evaluated and 11 studies were included. Random-effects meta-analysis was performed on body weight and measures of body composition and glycaemic control, to compare the effect of hypocaloric diet plus exercise with hypocaloric diet alone.RESULTSExercise interventions consisted of walking or jogging, cycle ergometer training, football training, or resistance training, and duration varied from 2 to 52!weeks. Body weight and measures of body composition and glycemic control decreased during both the combined intervention and hypocaloric diet alone. Mean difference in change of body weight (0.77 kg [95% CI: 2.03; 0.50]), BMI (0.34 kg/m2 [95% CI 0.73; 0.05]), waist circumference (1.42 cm [95% CI: 3.84; 1.00]), fat-free mass (0.18 kg [95% CI 0.52; 0.17]), fat mass (1.61 kg [95% CI 4.42; 1.19]), fasting glucose (+0.14 mmol/l [95% CI 0.02; 0.30]), HbA1c (0.06 % [95% CI 0.25; 0.13]), and HOMA-IR (+0.01 [95% CI: 0.40; 0.42]) was not statistically different between the combined intervention and hypocaloric diet alone. Two studies reported VO2max and showed significant increases upon addition of exercise to hypocaloric diet.CONCLUSIONAdditional effects of exercise to hypocaloric diet in adults with overweight or obesity and type 2 diabetes were not shown for body weight, body composition, or glycaemic control, while cardio-respiratory fitness improves.
MULTIFILE
Management of type 1 diabetes (T1D) is essential for a successful long-term treatment. This is especially important for teenagers transitioning to self-management. However, due to teenagers’ interests and lifestyles, T1D management isn’t often highly prioritized by teenagers, possibly leading todeficits in monitoring and health status. In this work, we aim to increase monitoring potential for teenagers by developing a mobile app that is centered around the lifestyle and needs of teenagers. We further emphasize patient-doctor communication by concentrating on the human behind the numbers. We contribute user requirements, a paper-prototype design of the T1D management app and an initial evaluation with medical staff such as diabetes nurses.
