Abstract
Background: Weight cycling, or repeated episodes of intentional weight loss, is related to negative cardiovascular health outcomes. Clinical diagnosis of overweight by healthcare providers is an important component of weight loss counseling, but such diagnoses may inadvertently promote weight cycling. We assessed the association between clinical diagnosis of overweight and history of weight cycling among adults in the United States with a history of being overweight.
Methods: Data from 5,512 adults aged 20 and older assessed in the nationally representative 2017-2020 National Health and Nutrition Examination Survey who reported ever having BMI≥25.0 kg/m2 were analyzed. Participants who reported ever being told by a doctor or healthcare provider that they were overweight were considered to have a clinical diagnosis of overweight. Weight cycling was defined as an episode of intentional weight loss of 10 pounds or more. Participant weight cycling history was categorized as having no episodes (reference), low weight cycling (1-5 weight loss episodes), or high weight cycling (6 or more episodes). We conducted multinomial logistic regression analysis of the association between a clinical diagnosis of overweight and level of weight cycling (none, low, or high). Covariates included gender, age, race/ethnicity, family income to poverty ratio, and education.
Results: Among US adults who had ever been overweight, 50.7% reported clinical diagnosis of overweight, 49.7% reported low weight cycling and 16.8% reported high weight cycling. Adults with a clinical diagnosis of overweight had higher relative odds of both low and high weight cycling (OR=3.45; 95%CI: 2,83, 4.20 and OR=8.78; 95%CI: 5.73, 13.48, respectively), compared with no weight cycling. Non-Hispanic white adults and men had the highest odds ratios for high weight cycling history.
Conclusions: Clinical diagnosis of overweight was associated with substantially higher odds of weight cycling among adults who have ever been overweight. Approaches to tailor weight loss counseling by healthcare providers that prevent weight cycling should be explored to minimize the physiological and psychosocial implications of frequent episodic weight loss among overweight adults.
