title: Metabolic syndrome and discrepancy between actual and self-identified good weight: Aerobics Center Longitudinal Study.
abstract: This study examined whether the discrepancy between measured and self-identified good weight (weight discrepancy) predicts metabolic syndrome (MetSyn). This study included 6,413 participants enrolled in the Aerobics Center Longitudinal Study (mean follow-up: 4.8±3.8 years). Weight discrepancy was defined as measured weight minus self-identified good weight. MetSyn was defined using standard definitions. Hazard ratios (HRs) and 95% confidence intervals (95% CIs) for incident MetSyn, by weight discrepancy category, were estimated using Cox proportional hazards regression. The multivariable-adjusted HR for MetSyn was 3.48 (95% CI=2.48-4.86) for those who maintained higher weight discrepancy over time compared to individuals with lower weight discrepancy. Additional adjustment for body mass index did not change this interpretation (HR=3.44; 95% CI=2.46-4.82). Weight discrepancy may be a useful screening characteristic and target for future interventions to further reduce the risk of chronic weight-related disorders, included MetSyn.
