Cholesterol-related knowledge, attitudes, and behaviors in a low-income, urban patient population.
To determine knowledge, attitudes, behaviors, and self-reported cholesterol measurement in a low-income, urban patient population, we conducted an interview survey of users and potential users of primary care services in a public health care system for low-income Harris County, Texas, residents. The response rate was 93%, with a final sample of 547 randomly selected subjects 18 years of age and older, who were Hispanic (54%), black (28%), non-Hispanic white (14%), and Asian, Native American, or other (4%). Results indicated that 76% had heard of serum or blood cholesterol, and 30% reported past cholesterol measurement. Knowledge that dietary saturated fat can raise blood cholesterol ranged from 11% in Hispanic men to 51% in non-Hispanic white men and women. A lower percentage of Hispanics correctly answered all knowledge questions, and Hispanics reported higher-fat food choices than blacks and non-Hispanic whites. More than 90% of the respondents expressed interest in more information on diet, 60% reported that they read nutrition labels, and 15% said they have been trying to reduce blood cholesterol levels. A lower percentage of Hispanics reported previous cholesterol measurement than blacks or non-Hispanic whites, a difference that persisted after adjusting for multiple factors associated with cholesterol measurement. Older age (older than 50) and more physician visits in the past year also were associated with past cholesterol measurement. Comparisons with national surveys show that cholesterol knowledge and actual measurement in this low-income sample lag behind those of the national population. Yet, despite gaps in knowledge and cholesterol measurement, respondents showed positive attitudes about and interest in cholesterol-lowering interventions.
