    Objective

    Weight dissatisfaction, defined as discordance between actual and goal weight, may be associated with increased risk for several obesity-related comorbidities. The purpose of the study was to examine the association between weight dissatisfaction and risk of developing type 2 diabetes.

    Methods

    This longitudinal study used data from 9,584 adults enrolled in the Aerobics Center Longitudinal Study with an average of 5.1±4.1 years of follow-up. Key variables included multiple measures of measured weight, self-reported goal weight, and incident diabetes. Weight dissatisfaction was defined as being above the median of measured weight minus goal weight. Cox proportional hazards regression estimated hazard ratios (HR) and 95% confidence intervals (95%CI) for diabetes incidence by weight dissatisfaction.

    Results

    HRs for time-until-diabetes diagnosis revealed that family history of diabetes (HR=1.46, 95%CI=1.13-1.90), age (HR=1.03, 95%CI=1.02-1.04), and weight dissatisfaction (HR=1.83, 95%CI=1.50-2.25) at baseline were statistically significant predictors. Longitudinally, higher risk was observed in individuals who either stayed dissatisfied (HR=2.98, 95%CI=1.98-4.48) or became dissatisfied (HR=1.51, 95%CI=0.79-2.89), compared to those who either stayed satisfied (HR=1.00, referent) or became satisfied (HR=0.98, 95%CI=0.46-2.10). After additional adjustment for BMI, the elevated HR for those who remained dissatisfied compared to those who remained satisfied persisted (HR=2.85, 95%CI=1.89-4.31).

    Conclusions

    Chronic weight dissatisfaction increased type 2 diabetes risk. Weight dissatisfaction, regardless of BMI, represents a potentially important psychophysiological modifier of the relationships between BMI and risk of type 2 diabetes and warrants greater attention in future studies of chronic disease risk.
