This study examined colon cancer screening knowledge and potential covariates (demographic, health, health care, and cancer information seeking) among adults of at least 45 years of age. Data were analyzed from the 2003 National Cancer Institute's (NCI's) Health Information National Trends Survey (HINTS 2003), a U.S. random-digit dial study. Our sample consisted of 3,131 adults (53.6% female, 77.9% White). The colon cancer screening knowledge questions assessed whether participants had heard of the fecal occult blood test (FOBT; 73.7%), knew the recommended start age (26.1%), knew the frequency of FOBT (39.5%), had heard of flexible sigmoidoscopy or colonoscopy (84.3%), knew the start age (39.6%), and knew the frequency with which to test (12.8%). Factors associated with lower knowledge (all equal to p < .05 in a multivariate analysis) included being younger (45 to 49 years old) or older (70 years old or more), African American or non-Hispanic other, unmarried; had lower educational attainment; had not visited a health care provider in the past year; had not previously undergone FOBT; and had never looked for cancer information. This study documents low rates of colon cancer screening knowledge in the general population, and identifies subgroups where health communication interventions are most warranted.

    • "Screening for CRC has been shown to reduce mortality as it facilitates early detection and prevention of the malignancy [8-10]. The recommended screening methods for early detection of colorectal cancer are fecal occult blood test (FOBT), flexible sigmoidoscopy [11], barium enema and colonoscopy [12]. "

    ABSTRACT: Perceived susceptibility to an illness has been shown to affect Health-risk behavior. The objective of the present study was to determine the risk taking behaviors and the demographic predictors of perceived susceptibility to colorectal cancer in a population-based sample. A cross-sectional study was carried out among 305 Malaysian adults in six major districts, selected from urban, semi-urban, and rural settings in one state in Malaysia. A self-administered questionnaire was used in this study. It was comprised of socio-demographics, risk-taking behaviors, and validated domains of the Health Belief Model (HBM). The mean (+/- SD) age of the respondents was 34.5 (+/- 9.6) and the majority (59.0%) of them were 30 years or older. Almost 20.7% of the respondents felt they were susceptible to colorectal cancer. Self-reported perceived susceptibility mirrored unsatisfactory screening behaviors owing to the lack of doctors' recommendation, ignorance of screening modalities, procrastination, and the perception that screening was unnecessary. Factors significantly associated with perceived susceptibility to colorectal cancer were gender (OR = 1.8, 95% CI 1.0-3.3), age (OR = 2. 2, 95% CI 1.2-4.0), ethnicity (OR = 0. 3, 95% CI 0.2-0.6), family history of colorectal cancer (OR = 3. 2, 95% CI 1.4-7.4) and alcohol intake (OR = 3.9, 95% CI 2.1-7.5). The present study revealed that screening behavior among respondents was unsatisfactory. Hence, awareness of the importance of screening to prevent colorectal cancers is imperative.

    ABSTRACT: Health communication and health information technology influence the ways in which health care professionals and the public seek, use, and comprehend health information. The Health Information National Trends Survey (HINTS) program was developed to assess the effect of health communication and health information technology on health-related attitudes, knowledge, and behavior. HINTS has fielded 3 national data collections with the fourth (HINTS 4) currently underway. Throughout this time, the Journal of Health Communication has been a dedicated partner in disseminating research based on HINTS data. Thus, the authors thought it the perfect venue to provide an historical overview of the HINTS program and to introduce the most recent HINTS data collection effort. This commentary describes the rationale for and structure of HINTS 4, summarizes the methodological approach applied in Cycle 1 of HINTS 4, describes the timeline for the HINTS 4 data collection, and identifies priorities for research using HINTS 4 data.

    ABSTRACT: This study examines potential predictors of perceived risk for colon cancer in a U.S. sample of 2,949 individuals aged 45 and older with no colon cancer history. We examined perceived comparative risk for colon cancer as the outcome in ordinal regression analyses, and perceived absolute risk for colon cancer in linear regression analyses. Potential predictors included demographics, current risk behaviors, self-reported health, family and personal cancer history, emotion variables (colon cancer worry, general anxiety, and fear of positive screening findings), general cancer beliefs (causes, lack of preventability, information overload), and cancer information seeking. Those who had poorer self-reported health, a family cancer history, and increased colon cancer worry had higher perceived comparative and absolute colon cancer risk (all ps < .05). Those who were younger, interviewed in Spanish, had increased anxiety, and information overload had higher comparative risk; those with a personal history of cancer and fear that colon cancer screening would result in positive findings had higher absolute risk (all ps < .05). We determined that older individuals, those with risk factors, and those with good subjective health may not realize their colon cancer risk. Those distressed about colon cancer and who report cancer prevention information overload may require different messages.
