ABSTRACT Obesity and its related co-morbidities place a huge burden on the health care system. Patients who know they are obese may better control their weight or seek medical attention. Self-recognition may be affected by race/ethnicity, but little is known about racial/ethnic differences in knowledge of obesity's health risks.
To examine awareness of obesity and attendant health risks among US whites, Hispanics and African-Americans.
Cross-sectional self-administered survey.
Adult patients at three general medical clinics and one cardiology clinic.
Thirty-one questions regarding demographics, height and weight, and perceptions and attitudes regarding obesity and associated health risks. Multiple logistic regression was used to quantify the association between ethnicity and obesity awareness, controlling for socio-demographic confounders.
Of 1,090 patients who were offered the survey, 1,031 completed it (response rate 95%); a final sample size of 970 was obtained after exclusion for implausible BMI, mixed or Asian ethnicity. Mean age was 47 years; 64% were female, 39% were white, 39% Hispanic and 22% African-American; 48% were obese (BMI ≥30 kg/m(2)). Among obese subjects, whites were more likely to self-report obesity than minorities (adjusted proportions: 95% of whites vs. 84% of African-American and 86% of Hispanics, P = 0.006). Ethnic differences in obesity recognition disappeared when BMI was >35 kg/m(2). African-Americans were significantly less likely than whites or Hispanics to view obesity as a health problem (77% vs. 90% vs. 88%, p < 0.001); African-Americans and Hispanics were less likely than whites to recognize the link between obesity and hypertension, diabetes and heart disease. Of self-identified obese patients, 99% wanted to lose weight, but only 60% received weight loss advice from their health care provider.
African-Americans and Hispanics are significantly less likely to self report obesity and associated health risks. Educational efforts may be necessary, especially for patients with BMIs between 30 and 35.

    ABSTRACT: Abstract Background: While knowledge of cardiovascular disease (CVD) has improved, it remains low among minority women, thereby contributing to disparities and posing health challenges. Moreover, substantial numbers of women do not recognize that excess weight imposes CVD risk and increases morbidity and decreases survival. In order to test the hypothesis that CVD knowledge is reduced among overweight and obese women, CVD knowledge and weight perception was compared among Hispanic and non-Hispanic white (NHW) women. Methods: Data from 382 Hispanic and 301 NHW women, participants in the Heart Health in Action database (n=829), were analyzed from a structured behavioral risk factor surveillance system (BRFSS) questionnaire to assess demographics, risk factors, and CVD knowledge. Multivariable logistic regression analysis was utilized to test for differences between Hispanic and NHW women regarding knowledge with covariates of age, education, and body mass index (BMI). Results: Hispanics (27%) were less likely than NHW (88%) to correctly identify the leading cause of death among women, (p<0.0001). Years living in the United States did not relate to the percentage of respondents who correctly identified the leading cause of death among women or knew the symptoms of a heart attack. Differences between Hispanic and NHW remained significant after adjustment for age, education, and BMI (p<0.0001). Hispanics (69.4%) were less likely than NHW (82.9 %) to correctly estimate weight (p<0.0001). Underestimation of weight was greater among Hispanics (24.8%) than NHW (5.0%); 48.5% of overweight Hispanic participants versus 12.7% of overweight NHW participants underestimated weight (p<0.0001) and 17.2% of obese Hispanic versus 0% of NHW obese participants (p=0.001) underestimated weight. The percentage underestimating the silhouette corresponding to their weight was related to years in the United States: 29.3% for<10 years, 38.3% with 10-19 years, and 49.3% with ≥20 years (p=0.01 for trend). Conclusions: Effective prevention strategies for at-risk populations need to target CVD knowledge and awareness among overweight and obese Hispanic women.

    ABSTRACT: Objective To measure knowledge of the health consequences of obesity among overweight/obese Black and Hispanic adults and examine the relationship to prior weight loss. Methods Knowledge of the health consequences of obesity was assessed among 410 Black and Hispanic adults with BMI ≥ 25 kg/m2 enrolled in a behavior change weight loss study. The relationship between obesity risk knowledge and previous weight loss was also examined. Results The majority of participants were knowledgeable of the risk of hypertension (94%), diabetes (96%), high cholesterol (91%), joint pains/arthritis (89%) and sleep apnea (89%) associated with obesity. Among post-menopausal age women, 53% were aware of the increased risk of breast cancer. There was no significant relationship between obesity risk knowledge and previous weight loss of 10 pounds or more (OR = 1.075, 95% CI: [0.808, 1.430]). Conclusions We found that knowledge of the health consequences of obesity was high, except for knowledge of the risk of breast cancer. Obesity risk knowledge was not associated with past weight loss. Practice implications Further health education is needed regarding the increased risk of breast cancer associated with obesity. Our data suggest that knowledge of the health consequences of obesity is not associated with weight loss success.
