Racial and ethnic differences in weight management behavior by weight perception status

Area of Science:

• Public Health
• Health Disparities
• Obesity Research

Background:

• Weight perception significantly influences health behaviors, yet its association with weight management strategies among diverse populations remains under-examined.
• Overweight and obesity are prevalent conditions, necessitating an understanding of factors that drive effective weight management across different racial and ethnic groups.

Purpose of the Study:

• To investigate racial and ethnic disparities in the relationship between how individuals perceive their weight and their engagement in weight management behaviors.
• To analyze these associations among a diverse sample of overweight and obese adults in the United States.

Main Methods:

• Utilized data from the National Health and Nutrition Examination Survey (1999-2006), including 11,319 non-Hispanic White, non-Hispanic Black, and Mexican American adults (aged ≥20 years).
• Calculated Body Mass Index (BMI) to define overweight (25 ≤ BMI < 30) and obesity (BMI ≥ 30).
• Assessed weight perception (correct vs. misperception) and weight management behaviors (e.g., trying to lose weight, not gain weight, weight goal) using logistic regression models stratified by race/ethnicity.

Main Results:

• Correct weight perception was positively associated with weight management behaviors across all studied racial/ethnic groups.
• Overweight non-Hispanic Black adults with weight misperception were less likely than their non-Hispanic White counterparts to attempt weight loss (aOR=0.7) or weight gain prevention (aOR=0.7).
• Obese non-Hispanic Black adults with weight misperception were less likely to desire weight reduction compared to obese non-Hispanic Whites (aOR=0.5).

Conclusions:

• The association between weight perception and weight management behaviors varies significantly by race and ethnicity.
• Addressing weight misperceptions may be crucial for promoting effective weight management, particularly within minority populations.
• Future interventions should consider tailored approaches to weight perception and management for diverse racial and ethnic groups.
