Applying Rogers' framework to evaluate public awareness and knowledge of medical genetics in a developing country.

ABSTRACT: Public knowledge of medical genetics is essential for better establishment of its services but has been rarely evaluated based on distinguished types of knowledge. We designed and validated a new self-administered questionnaire in Farsi (Persian language) to assess public knowledge of medical genetics based on Rogers' framework. This framework divides knowledge into three types of awareness, how-to (practical) and principles knowledge which refer to knowing the existence, proper use, and theoretical principles of an innovation, respectively. We asked consecutive individuals (n?=?306, age???20 years) visiting health centers in different regions of Yazd, a city in central Iran, to fill out the questionnaire. After validation, we analyzed 280 of the questionnaires which revealed a high degree of internal consistency (Cronbach's alpha 0.90) and a positive linear relationship among the scores of different knowledge. Our respondents had relatively fair awareness and how-to, but generally poor principles knowledge with statistically significantly better scores in females and those with higher education. We observed tangible strengths in topics such as consanguineous marriage, thalassemia, and hereditary predisposition to diabetes and cardiovascular disorders, and weaknesses in areas such as genetic testing and genetics of cancer. Notably, experience of premarital genetic counseling did not show any significant effect, but having a relative with a genetic disorder was significantly linked to better awareness scores. Our study provides a reliable and self-administered questionnaire for the assessment of public knowledge of medical genetics. Despite revealing important strengths and weaknesses in our population sample, larger scale evaluations in Iran and other developing countries are needed for better understanding of the public knowledge as the prerequisite for designing appropriate educational programs.

Project description:IntroductionGood knowledge and early identification of chronic kidney disease (CKD) can help in preventing disease progression in its early stages and reducing undesired outcomes. The aim of the current study was to assess the level of public knowledge about CKD, determine predictors of better knowledge, and to construct and validate a CKD knowledge scale for public health assessment and research use.MethodsA community-based cross-sectional study was conducted using an electronic self-administered questionnaire. All people living in Lebanon and being 18 years of age and above were considered eligible for recruitment. CKD knowledge was assessed by a 37-item scale that was constructed by principal component analysis and then validated. The score of the CKD knowledge scale was computed from the extracted factors. A multivariable binomial logistic regression model evaluated the sociodemographic and clinical predictors of the knowledge score.ResultsA total of 1308 participants were included. The scale items converged over 9 factors with Eigenvalue greater than 1 and explaining 53.26% of the total variance, and the total scale had a high Cronbach's alpha of 0.804. All items of the scale significantly correlated with the full scale with correlation coefficients ranging from 0.082 to 0.558. The ROC curve analysis determined an optimal cutoff point of better knowledge at 47.5 with 70.6% sensitivity and 44.2% specificity. The CKD knowledge score had a median of 51.00 (IQR 47.00-55.00). Higher knowledge score was significantly associated with old age (ORa = 1.018, 95% CI 1.006-1.030, P = 0.003),, occupation (ORa = 3.919, 95% CI 2.107-7.288, P < 0.001), and recent renal function assessment (ORa = 2.314, 95% CI 1.532-3.495, P < 0.001). However, a lower knowledge score was significantly associated with lower level of education (ORa = 0.462, 95% CI 0.327-0.653, P < 0.001).ConclusionA reliable tool to assess public knowledge and awareness about CKD was developed and validated. The overall knowledge was good, however, important gaps in CKD awareness were detected in some areas and subpopulations. Therefore, public health stakeholders need to implement targeted CKD educational activities to minimize the disease burden.

Project description:BackgroundDementia is a global public health priority. Many modifiable factors have been shown to influence the development of dementia, but these factors are not adequately known by the general public. This study aimed to assess public awareness of the factors that are associated with dementia in China.MethodsA cross-sectional study was conducted from May to October 2019 using an Internet-based questionnaire. Data on basic sociodemographic characteristics were collected, and the knowledge of risk and protective factors for dementia was investigated. Logistic regression analysis was performed to compare levels of the knowledge of factors associated with dementia across populations with different demographic characteristics.ResultsData from 3338 respondents were analyzed. The percentages of participants who accurately identified the risk factors of dementia were follows: 84.24% for negative affect, 65.07% for alcohol use, 56.68% for smoking, 48.74% for hypertension, and 42.66% for diabetes. The percentages of participants who accurately identified the protective factors for dementia were follows: 90.00% for exercise, 84.69% for social activity, 80.92% for intelligence games, 74.45% for reading, and 6.14% for antihypertensive or hypolipidemic drugs. The majority of Chinese people correctly recognized the role of lifestyle factors in the development of dementia but not medical factors. The levels of knowledge of the factors associated with dementia were significantly distinct across populations with different characteristics. The following sociodemographic characteristics were associated with more comprehensive knowledge of dementia risk and protective factors: women, young age, high education levels, nonmanual jobs, and contact with patients with dementia.ConclusionsPublic awareness and knowledge of risk and protective factors for dementia in China are still insufficient. More efforts are needed to publicize information to reduce the risk of dementia.
