Dietary and exercise change following acute cardiac syndrome onset: A latent class growth modelling analysis

The study determined sub-group trajectories of change on measures of diet and exercise following acute coronary syndrome. 150 participants were assessed in hospital, and 1month and 6 months later on measures including physical activity, diet, illness beliefs, coping and mood. Change trajectories were measured using latent class growth modelling, and multinomial logistic regression was used to predict class membership. These revealed changes in exercise were confined to a sub-group of participants already reporting relatively high exercise levels; those eating less healthily evidenced modest dietary improvements. Coping, gender, depression and perceived control predicted group membership to a modest exten
