• Description:
  Objectives
  
  To determine whether a cognitive intervention delivered by lay health educators (LHEs) in senior centers was effective in improving cognition in obese older adults.
  
  Methods
  
  This cluster randomized trial was conducted in 16 senior centers from which 228 senior adults were recruited. The centers were randomized to either the cognitive intervention or a control, weight-loss intervention. The primary outcome variable, cognitive function, was measured using the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS).
  
  Results
  
  Analyses of RBANS indices as continuous variables did not indicate significant differences between arms. However, after adjusting for baseline delayed memory, gender, and baseline body mass index, seniors in the cognitive intervention arm had a 2.7 times higher odds of a reliable improvement (clinically significant) in delayed memory from baseline as compared to those in the control intervention (95% CI, 1.3-5.6, p=.011). The intervention effect was not significant for the proportion showing reliable improvement in immediate memory or in attention. Attendance at the 12-session program was high with an average of 83% (67-92%) sessions attended and 87% of participants in the cognitive arm indicating they would recommend the program.
  
  Discussion
  
  Cognitive interventions can be effectively delivered in the community by LHEs.
