Physical Activity Patterns among Individuals with Prediabetes or Type 2 Diabetes across Two Years-A Longitudinal Latent Class Analysis.

[{"label":"BACKGROUND","text":"This study aimed to identify distinct profiles of physical activity (PA) patterns among individuals with prediabetes or type 2 diabetes participating in a two-year PA trial and to investigate predictors of the profiles."},{"label":"METHODS","text":"Data ( = 168, collected 2013-2020) from the cohort of a randomized trial aimed at increasing PA in individuals with prediabetes and type 2 diabetes were used. PA and sedentary behaviours were assessed by waist-worn ActiGraph GT1M accelerometers at baseline and at 6, 12, 18 and 24 months. Fifteen PA and sedentary variables were entered into a latent class mixed model for multivariate longitudinal outcomes. Multinominal regression analysis modelled profile membership based on baseline activity level, age, gender, BMI, disease status and group randomisation."},{"label":"RESULTS","text":"Two profiles of PA patterns were identified: \"Increased activity\" ( = 37, 22%) included participants increasing time in PA and decreasing sedentary time. \"No change in activity\" ( = 131, 78%) included participants with no or minor changes. \"Increased activity\" were younger ( = 0.003) and more active at baseline ( = 0.011), compared to \"No change in activity\". No other predictor was associated with profile membership."},{"label":"CONCLUSIONS","text":"A majority of participants maintained PA and sedentary patterns over two years despite being part of a PA intervention. Individuals improving PA patterns were younger and more active at baseline."}]
