Reach and Effectiveness of a Weight Loss Intervention in Patients With Prediabetes in Colorado
Introduction Although lifestyle interventions are effective in delaying the onset of diabetes , translating these lessons to routine health care setting s remains a challenge . We investigated the effectiveness of a theory-based , brief , small-group weight loss intervention for diabetes prevention . A secondary purpose was to determine the potential reach of the intervention . Methods A total of 14,379 members of an integrated health care organization newly diagnosed with prediabetes were potentially eligible to participate in this matched cohort longitudinal study . Of this group , 1,030 attended a 90-minute , small-group session that targeted personal action planning for healthful eating , physical activity , and weight management . We accessed electronic medical records to select 1 to 2 controls ( matched on impaired fasting glucose measurement , sex , age , and body mass index ) for each member who attended the small-group session ( n = 760 ) . Weight change , as recorded in the medical record , was the primary outcome . Mixed models analyses were used to adjust for matching variables and covariates and to account for individual r and om effects over time . Results Small-group participants  lost significantly more weight than did their matched controls . A significantly higher proportion of small-group participants  lost at least 5 % of their body weight compared with controls . Conclusion A brief , small-group weight loss intervention was effective . However , it did not reach broadly into the population that was at risk for diabetes
