Background:Health literacy is a measure of an individual's ability to read, comprehend, and act on medical instructions. Limited health literacy can reduce the adults’ ability to comprehend and use basic health-related materials, such as prescription, food labels, health education pamphlets, articles, appointment slips, and health insurance plans, which can affect their ability to take appropriate and timely health care action. Nowadays, low health literacy is considered a worldwide health threat. So, the purpose of this study was to assess health literacy level in older adults and to investigate the relationships between health literacy and health status, health care utilization, and health preventive behaviors.Materials and Methods:A cross-sectional survey of 354 older adults was conducted in Isfahan. The method of sampling was clustering. Health literacy was measured using the Test of Functional Health Literacy in Adults (TOFHLA). Data were collected using home interviewing. Health status was measured based on self-rated general health. Health care utilization was measured based on self-reported outpatient clinic visits, emergency room visits, and hospitalizations, and health preventive behaviors were measured based on self-reported preventive health services use.Results:Approximately 79.6% of adults were found to have inadequate health literacy. They tended to be older, had fewer years of schooling, lower household income, and were females. Inadequate health literacy was associated with poorer general health (P < 0.001). Health literacy level was negatively associated with outpatient visits (P = 0.003) and hospitalization (P = 0.01). No significant association was found between health literacy level and emergency room utilization. Self-reported lack of PSA (Prostate-Specific Antigen) test (P < 0.001) and fecal occult blood test (FOBT; P = 0.003) was higher among individuals with inadequate health literacy than those with adequate health literacy. No significant association was found between health literacy level and mammogram in the last 2 years.Conclusion:Low health literacy is more prevalent in older adults. It indicates the importance of health literacy issue in health promotion. So, with simple educational materials and effective interventions for low health literacy group, we can improve health promotion in the society and mitigate the adverse health effects of low health literacy.
Background:Colorectal cancer is one of the most important and most common cancers and the second leading cause of cancer deaths worldwide. Every year, nearly 1 million new cases of colorectal cancer are recognized around the world and nearly half of them lose their lives due to the disease. The statistics reveal shocking incidence and mortality from colorectal cancer, therefore secondary prevention of this cancer is important and research has shown that by early diagnosis 90% of patients can be treated. Among the colorectal cancer screening tests, fecal occult blood test (FOBT) takes the priority because of its convenience and also low cost. But due to various reasons, the participation of people in this screening test is low. The goal of this study is to assess the factors that affect participation of population at average risk in colorectal cancer screening programs, based on health belief model structures.Materials and Methods:A cross-sectional survey of 196 individuals, more than 50 years old, was conducted in Isfahan. Ninety-eight people of the target group were selected from laboratories while they came there for doing FOBT test; the method of sampling in this group was random sampling. The method of data collection in the other 98 individuals was by home interview and they were selected by cluster sampling. The questionnaire used was based on health belief model to assess the factors associated with performing FOBT. The data collected were analyzed using descriptive and inferential statistical methods.Results:The mean score of knowledge in the first group was 48/5 ± 11/7 and in the second group was 36/5 ± 19/3. Individuals in the first group were more likely to be married, had more years of schooling, and better financial status. There were significant relationships between knowledge (P<0.001), perceived susceptibility (P<0.001), perceived severity (P<0.001), perceived barriers (P<0.001), and self-efficacy (P<0.001) in the two groups. There was no significant association between the perceived benefits in the two groups. Those people who have had FOBT test in last year in each group reported better score of Health Belief Model model structures.Conclusion:According to this study, it seems that there is an urgent need to pay more attention to this disease and its prevention through screening. With a better understanding of factors affecting the test, it can be a useful step to reduce the rate of death and costs, and improve the community health outcomes.
