Factors Associated with Awareness, Attitudes and Practices Regarding Common Eye Diseases in the General Population in a Rural District in Bangladesh: The Bangladesh Population-based Diabetes and Eye Study (BPDES)

Public Awareness of Common Age-Related Eye Diseases in Northern Saudi Arabia

Background: Visual impairment and blindness pose substantial public health challenges in Saudi Arabia, especially among the elderly susceptible to blinding eye diseases. Assessing awareness of age-related eye diseases (AREDs) is vital for addressing vision loss in this demographic. However, there is a lack of research on ARED awareness in Northern Saudi Arabia, underscoring the need for evidence-based data from adult populations to craft effective health promotion strategies.

METHODS

This population-based descriptive survey was conducted on 411 Saudi adults aged 18-70 residing in Arar City, Saudi Arabia, over six months from September 2023. Random sampling was employed, and awareness levels were assessed using a pre-designed questionnaire. Data analysis was performed using Statistical Product and Service Solutions (SPSS, version 20.0; IBM SPSS Statistics for Windows, Armonk, NY).

RESULTS

 Among the 411 participants, 225 (54.7%) were aged 18-29 years, 312 (76%) were females, and 299 (72.6%) held a bachelor's degree or diploma. Regarding awareness, 71.3% knew about cataracts, but nearly half erroneously believed it could be treated solely medically. For diabetic retinopathy (DR), 366 (89%) recognized lifestyle modifications, and 378 (92%) understood screening as preventive measures. Most participants understood prevention methods for all four diseases, but misconceptions about treatment options were observed. Awareness of glaucoma and age-related macular degeneration (ARMD) was lower. No significant age-related differences were found in awareness, except for cataracts (P = 0.001). Education significantly influenced awareness of cataracts, DR, and glaucoma (P = 0.001, 0.013, and 0.008, respectively), but not ARMD (P = 0.606). The study found that the internet is the primary source of information on AREDs for most participants, except for cataracts, where friends and relatives are prominent.

CONCLUSION

The study reveals varying awareness levels of AREDs among Saudi adults. Although most participants understood preventive measures, misconceptions about treatment underscore the need for accurate education channels. Healthcare professionals must ensure information reliability to effectively combat misinformation and enhance awareness of AREDs.

Knowledge about age-related eye diseases in the general population in Germany

BACKGROUND

With a rising prevalence of age-related eye diseases, prevention and early diagnosis of these conditions are key goals of public eye health. Disease-related knowledge in the general public supports these goals but there is little data available. Thus, we have assessed knowledge of cataract, glaucoma, age-related macular degeneration (AMD) and diabetic eye disease in the German adult general population in a cross-sectional study and identified target groups for health education interventions.

METHODS

Knowledge assessment content was identified based on a literature review, expert input, and a list of items was generated after a qualitative selection process. The resulting 16-item instrument (4 items per condition) was administered to 1,008 participants from a survey panel, demographically representative of the adult German population. Test properties were evaluated based on a Rasch model and multiple correspondence analysis (MCA). Binary-logistic regression analysis was performed to investigate associations with age, sex, education level, employment status, marital status, income, reported health status, visual difficulties, and recent general practitioner (GP) and ophthalmologist consultations.

RESULTS

Replies were correct for a median of 9 out of 16 (range 2 - 16) items, which differed between conditions (p < 0.0001). Most responses were correct for cataract items (median: 3 / 4) and least were correct for AMD items (median: 2 / 4). 27%, 9%, 1% and 19% of respondents replied correctly to all cataract, glaucoma, AMD and diabetic eye disease-related items, respectively. Rasch analysis suggested an adequate targeting of items and in MCA, no evidence of multidimensionality was present. Older age, being retired, decreased general health and recent GP or ophthalmology consultations were significantly associated with more knowledge about common eye conditions (p ≤ 0.005). GP or ophthalmology consultations remained significant in a multivariable model (p ≤ 0.011).

CONCLUSIONS

Knowledge gaps regarding eye health are considerable in the German general population and should therefore be addressed in educational interventions targeting the public. Special attention when designing such campaigns needs to be paid to infrequent users of the healthcare system. Knowledge of AMD seems to be poorer compared to other eye conditions.

A systematic literature review for evaluation of knowledge, attitude, and self-care practice regarding common eye diseases in the healthy general population

Background and purpose

Increasing people's knowledge and then changing their attitude and practice with the aim of taking care of their eye health are very important. Considering the importance of the mentioned topic, the main goal of this study was to evaluate the knowledge, attitude, and practice about eye diseases in the general population of the world in the form of a systematic literature review.

Materials and Methods

This study was a systematic literature review study, and to do it, a systematic search was conducted in internationally available databases including Web of Science, ScienceDirect, Scopus, PubMed, and Google Scholar in the time range of 1998 to 2023. Finally, considering the inclusion and exclusion criteria of the study, the results of 18 articles were extracted.

Results

The findings showed that in general, people's level of knowledge about glaucoma was lower compared to other eye diseases, and the level of knowledge of men and women about eye diseases was different. In addition, the results showed that there was significant relationship between age and knowledge of various eye diseases. The results of all evaluated studies showed that people with higher education have more knowledge about eye diseases.

Conclusion

Based on this, it can be concluded that as glaucoma is one of the most important causes of blindness worldwide, it is necessary to plan to increase the level of public knowledge to recognize the symptoms and complications of this disease. In addition to that, it is necessary to increase people's advertisement by ophthalmology centers and eye specialists about the use of glasses and also to encourage people to visit the eye physician regularly.

Barriers to the uptake of eye health services of the children in rural Bangladesh: A community-based cross-sectional survey

Globally, ocular morbidity and disability among children are major public health concerns. This study was designed to explore the health-seeking behaviours of parents in Bangladesh whose children have ocular problems. A cross-sectional mixed method was followed for this study. The method was designed to measure the eye health care-seeking practices of caregivers/parents with children with ocular morbidity in three unions (the lowest administrative geographical area comprising 30,000-50,000 population) of the Raiganj Upazila under the Sirajganj District of Bangladesh. The study period was from January to April 2017. Face-to-face interviews using a semi-structured quantitative questionnaire with the caregivers and KI were conducted among the health service providers during the study period. This was the first community-based study conducted in Bangladesh to find out caregivers' health-seeking behaviour with identified ocular morbidity. Among 198 confirmed cases of childhood ocular problems, only 87 (43.9%) parents sought health care for their children's ocular morbidities. Better health-seeking behavior was found among the wealthier families. Proportions were 55.3% and 36% among wealthy and low-income families, respectively. Affluent families sought care from qualified service providers. Educated household heads chose qualified service providers for their children at a higher rate than illiterate household heads. Lack of knowledge, lack of awareness and financial constraints are significant barriers to seeking proper health care. More than half of the caregivers did not seek any eye care services for their children. Socio-demographic factors, and financial constraints play an essential role in the health-seeking behaviour of the parents.

Awareness and Knowledge of Glaucoma and Its Associated Risk Factors Among Adult Population in the Jazan Region, Saudi Arabia

Introduction Glaucoma can be considered a heterogeneous group of diseases with characteristic progressive optic neuropathy, which causes the development of visual field dysfunctions and irreversible blindness. Glaucoma is the most prevalent cause of irreversible blindness worldwide. Aim This study aimed to assess the awareness and knowledge of glaucoma and its associated risk factors among the adult population in Jazan, Saudi Arabia, in 2022. Methods A community-based cross-sectional study was conducted with 384 participants aged 40 years and above in the Jazan region. A convenience sampling technique was adopted to obtain the target sample size. Data were collected using a self-administered electronic questionnaire on Google Forms. Results A majority (73.1%) of the 387 respondents to the questionnaire were in the age group of 40-50 years, with the average age being 47.43 years. No statistically significant difference was found between different age groups' level of knowledge (p=0.769). In addition, the difference between levels of knowledge based on participants' residence was also statistically insignificant (p=0.387). Of the participants who were not diagnosed with glaucoma, 55% had poor knowledge of glaucoma; however, only 3.10% of the participants diagnosed with glaucoma had poor knowledge of the condition. Consequently, there was a statistically significant difference between participants' levels of knowledge based on their diagnosis of glaucoma (p=0.04). Conclusion The study revealed low knowledge and awareness levels regarding glaucoma among adults aged 40 years and above in the Jazan region.

Risk factors associated with elevated intraocular pressure: a population-based study in a rural community of Bangladesh

OBJECTIVE

High intraocular pressure (IOP) is one of the major modifiable risk factors for glaucoma. The objective was to examine socio-demographic and clinical factors related to IOP.

METHODS AND ANALYSIS

This study was conducted among 3097 adults residing in a rural area of Bangladesh, with all participants undergoing clinical and ophthalmological evaluations. The measurement of IOP was carried out using of a rebound Tonometer called Icare pro. Multiple logistic regression analysis was employed to identify variables associated to IOP levels of 21 mm Hg or above. Adjusted OR (aOR) and 95% CI were reported.

RESULTS

This study found that, in total, 9% of the study population had high IOP in one or both eyes. Elevated IOP was significantly associated with respondents who were service holders (aOR 2.52; 95% CI 1.48 to 4.31), had a lower education level (aOR 1.55, 95% CI 1.07 to 2.23), used biomass fuel (aOR 2.00; 95% CI 1.09 to 3.67), belonged to a higher socioeconomic position (aOR 1.55, 95% CI 1.07 to 2.23) and had obesity (aOR 2.00; 95% CI 1.07 to 3.73), hypertension (aOR 1.32; 95% CI 1.01 to 1.73) or history of diabetes (aOR 2.44; 95% CI 1.67 to 3.55), after adjusting for covariates including age, sex, marital status, light source and tobacco consumption, in a multiple regression analysis.

CONCLUSION

Chronic diseases, such as hypertension and diabetes, obesity and sociodemographic characteristics such as high socioeconomic status and use of biomass fuels, have all been linked to elevated IOP. Patients with chronic diseases should undergo for IOP testing regularly.

Development and validation of a questionnaire for assessing parents' health literacy regarding vision screening for children: a Delphi study

Preschool vision screening is recommended to reduce the incidence of amblyopia that persists into adulthood. However, parent's perceptions regarding the importance of screening and early intervention may constitute a significant barrier to seeking vision exams and pursuing treatment. The aim of this study is to develop and validate a questionnaire for assessing parent's awareness, perception and health literacy of children's vision tests. The questionnaire was developed using the Delphi method with experts from the fields of pediatric ophthalmology, optometry, orthoptics, pediatric medicine, social sciences and Mother and Child Health Care centers. Experts were provided with drafts of the questions iteratively in three rounds until a consensus was reached independently on the relevant items, coherently language and redundancies. For the first, second and third stages of the Delphi process, 17, 15 and 13 experts participated in the panel respectively. Validity was achieved by wide consensus among the panel on the relevance of each question, of 75%, 85% and 90%, for the three rounds respectively. Here we describe the final questionnaire, EYES: Evaluating Young-Children Eye health Survey, which includes 31 questions regarding demographics, ocular history, parental health literacy, and perceptions of vision and vison exams.

Development of Knowledge, Attitude and Practice Questionnaire for age-related macular degeneration patients

AIM

To develop and validate a questionnaire to evaluate knowledge, attitude and practice of patients diagnosed with age-related macular degeneration (AMD) who have undergone intravitreal injection treatment.

METHODS

This study was conducted among patients diagnosed with AMD in Kuala Lumpur. The generation of the instrument included four phases which included item and domains development, content, face validity and exploratory factor analysis. Content validity and modified Kappa was used for validation of knowledge domain. Exploratory factor analysis was used for validation of both attitude and practice domains. Face validity was conducted in 12 patients, content validity was ascertained in 120 patients and test-retest reliability was determined in 39 patients with AMD.

RESULTS

Content validity index (CVI) and modified kappa showed excellent values for most items in the knowledge domain with CVI for item (I-CVI) values between 0.78-1.0 and Kappa values of >0.74. The Kaiser-Meyer-Olkin (KMO) sampling adequacy showed acceptable scores of 0.70 and 0.75 for both attitude and practice domains respectively and Bartlett's Test of sphericity were significant (χ2 =0.00, P<0.001). Factor analysis resulted in five factors with thirty items for attitude domain and four factors with twenty items for practice domain. The Cronbach's alpha showed acceptable values for all items in knowledge, attitude and practice domain with values >0.70 and good test-retest reliability. The final version of the questionnaire consisted of 93 items from four sections consisting of demographic details, knowledge, attitude and practice.

CONCLUSION

The findings of this validation and reliability study show that the developed questionnaire has a satisfactory psychometric property for measuring KAP of patients diagnosed with AMD undergoing intravitreal injection treatment.

Awareness of Common Eye Diseases and Their Risk Factors-A Nationwide Cross-Sectional Survey among Adults in Poland

Public knowledge and awareness of eye diseases may influence individuals' behaviors toward the use of eye care services and prevention methods. The objective of this study was to assess the awareness of common eye diseases and their risk factors among adults in Poland as well as to identify factors associated with knowledge of eye diseases. This nationwide cross-sectional web-based survey was carried out in December 2022 on a representative sample of 1076 adults in Poland. Most of the respondents had heard of cataracts (83.6%), glaucoma (80.7%), conjunctivitis (74.3%), and hordeolum (73.8%). Awareness of dry eye syndrome was declared by 50% of respondents, and 40% were aware of retinal detachment. Among the respondents, 32.3% had heard of AMD, and 16.4% had heard of diabetic retinopathy. A lack of awareness of glaucoma was declared by 38.1% of respondents, and 54.3% declared a lack of awareness of risk factors for AMD. Gender, age, and the presence of chronic diseases were the most important factors (p < 0.05) associated with awareness of common eye diseases and risk factors for glaucoma and AMD. This study demonstrated a low level of awareness of common eye diseases among adults in Poland. Personalized communication on eye diseases is needed.

The social construction of genomics and genetic analysis in ocular diseases in Ibadan, South-western Nigeria

Genomics, an emerging field to improve public health practice, has potential benefits to understanding ocular diseases. This study explored the social construction of genomics in ocular diseases in the blind community in Ibadan, Nigeria, through two focus group discussions and twelve in-depth interview sessions conducted among people living with ocular disorders. The data were thematic and content-analysed. Although the participants had limited knowledge about ocular diseases, genomics, and their nexus, they maintained a positive attitude toward its potential benefits. This informed their willingness to participate in genomics testing for ocular diseases. The participants preferred saliva-based sample collection over blood-based, and expressed concern for the procedure and accrued benefits of genomics studies. Thus, public sensitisation about ocular diseases and client-centred genomics testing procedures should be engendered.

Emergent Ophthalmic Disease Knowledge among Non-Ophthalmologist Healthcare Professionals in the Western Region of Saudi Arabia: Cross-Sectional Study

Background:

Patients with emergent ophthalmic diseases are likely to be examined by healthcare providers before an ophthalmologist, so it is essential that nonspecialists have adequate knowledge for recognition and preliminary diagnosis.

Objectives:

To assess knowledge of retinal detachment, acute angle-closure glaucoma, temporal arteritis, and central retinal artery occlusion among non-ophthalmologist healthcare professionals.

Methods:

We conducted an observational cross-sectional study of 351 healthcare workers, including medical residents, nurses, pharmacists, and optometrists, in western Saudi Arabia using a self-report questionnaire.

Results:

Total knowledge scores were 75.21% for retinal detachment and 74.9% for acute angle-closure glaucoma, but only 44.15% for temporal arteritis and 41.88% for central retinal artery occlusion. Stepwise logistic regression revealed that level of education was the most significant factor influencing knowledge of different eye diseases.

Conclusion:

Ophthalmologists are encouraged to promote greater awareness and provide other healthcare professionals with the knowledge required to recognize emergent eye diseases for early detection.

Sociodemographic correlates of knowledge about high sodium-related diseases among adults in Malaysia

The prevalence of high sodium-related diseases is increasing across the globe. Knowledge plays an important role in disease prevention. The objective of the present study was to examine sociodemographic factors associated with knowledge of high sodium-related diseases. The Malaysian Community Salt Survey (MyCoSS) was used in the present study for secondary analyses. It is a nationwide cross-sectional survey that was conducted in Malaysia. A non-parametric test to evaluate trends and a negative binomial regression were utilised to assess knowledge of high sodium-related diseases. Income, educational level, gender, ethnicity, house locality and hypertension were found to be significantly associated with knowledge of high sodium-related diseases. In particular, higher income earners, well-educated people, women, Malays, urban dwellers and hypertensive adults were more likely to have acquired a lot of knowledge of high sodium-related diseases compared to that acquired by lower income earners, less-educated people, men, individuals of other ethnic groups, rural dwellers and nonhypertensive adults. In conclusion, sociodemographic factors and hypertension play an important role in knowledge acquired about high sodium-related diseases. The findings of the present study could inform a future policy directed towards increasing knowledge about high sodium-related diseases among the population in Malaysia.

Knowledge of and Intention to Participate in Physical Activity Programs and Their Associated Sociodemographic Factors in People with High Blood Pressure in a Rural Area of Bangladesh: Initial Investigation from a Cluster Randomized Controlled Trial

This initial investigation aimed to investigate the knowledge of the health benefits of physical activity (PA) and attitudes towards participation in PA. The study recruited 307 people aged 30-75 years with hypertension as part of a cluster randomized controlled trial from a rural area in Bangladesh. Of the 307 participants, 135 participated less than 2.5 h of physical activity per week, from which we collected data on attitudes toward PA. Regression analysis and Rasch analysis were used. More than 85% of homemakers, employees or businesspersons were willing to take part in PA. Based on the combined score from the knowledge and attitude items, 46% of people endorsed PA programs; proportions were higher in men than women (53% vs. 41%). After adjusting for covariates, men (odds ratio, 95% confidence interval (CI) 3.50, 1.72-7.11) compared to women and people with at least primary levels of schooling (OR 3.06, 95% CI, 1.27-7.38) compared with those with no education were more likely to organize or take part in any PA programs. People have positive attitudes towards PA but do not feel obligated to participate in PA programs. Future programs are needed to promote awareness and motivational interventions for PA, especially targeting women and people with low education levels, should be developed and implemented.

Knowledge, Attitude, Practices and Associated Factors Towards Trachoma Among People Living in Arba Minch Zuria District, Gamo Zone, Southern Ethiopia

Background

Trachoma is the second leading cause of blindness in the world affecting the poorest communities. Despite many interventions undertaken on prevention and control for trachoma, Ethiopia has failed to achieve the 2020 elimination goal.

Objective

To assess knowledge, attitude, practice and its associated factors toward trachoma infection among people living in Arba Minch Zuria district Gamo zone, Southern Ethiopia.

Methods

A community-based cross-sectional study was conducted from December 2019 to June 2020. Data were collected using a pretested interviewer-administered questionnaire from 796 randomly selected individuals. Epi Info version 7 was used to enter and clean the data and exported to SPSS V20 for analysis. A multivariable logistic regression analysis model was fitted to identify factors associated with the outcome variables.

Findings

Among 796 interviewed participants, 611 (76.8%) had inadequate knowledge toward trachoma infection and 244 (30.7%) had unfavorable attitude. Individuals who had no formal education (AOR=0.365, 95%CI: 0.212–0.626) and primary education (AOR=0.58, 95%CI: 0.35–0.962) were negatively associated with adequate knowledge towards trachoma infection. Being a farmer (AOR=0.063, 95%CI: 0.008–0.52), merchant (AOR=0.022, 95%CI: 0.003–0.194), student (AOR=0.026, 95%CI: 0.003–0.225) or housewife (AOR=0.03, 95%CI: 0.004–0.256) were negatively associated with adequate knowledge. Those study subjects whose wealth index were lowest (AOR=0.49, 95%CI: 0.27–0.878), second (AOR=0.38, 95%CI: 0.21–0.69) and middle (AOR=0.36, 95%CI: 0.199–0.658) percentiles negatively associated with adequate knowledge. A short distance to fetch water (AOR=2.53, 95%CI: 1.18–5.415) was positively associated with adequate knowledge about trachoma infection. Environmental cleanliness (AOR=2.224, 95%CI: 1.518–3.257), being male (AOR=1.848, 95%CI: 1.332–2.565) and distance from home to health facility (AOR=1.845, 95%CI: 1.308–2.600) were significantly associated with attitude status.

Conclusion

Considerable numbers of people have unfavorable attitude and inadequate knowledge about trachoma infection. Awareness creation through community mobilization and sensitization should be strengthened.

Factors Associated with Physical Activity among People with Hypertension in a Rural Area in Bangladesh: Baseline Data from a Cluster Randomized Control Trial

The health benefits of physical activity (PA) are well recognized, and PA levels vary in different populations. The study aimed to investigate PA levels and associated sociodemographic factors among people with hypertension in a rural area in Bangladesh. Baseline data were part of a cluster randomized controlled trial of 307 adults aged 30-75 years to study the effectiveness of PA and lifestyle changes in lowering blood pressure. The outcome variables were PA at work, commuter, recreation, metabolic equivalent task (MET)-minute per week and sitting time. Total 68 (22.1%) people participated in vigorous-intensity activity, 23 (7.5%) participated in moderate-intensity sports. Overall, 83% of people were physically active more than 600 MET-min. Women (OR 2.95, 95% CI, 1.36-6.39) compared to men, and people with no education (OR 4.47, 95% CI, 1.62-12.33) compared to people with secondary school certificates or above were less physically active. Of total PA, 63% were work-related, and 1% were recreation-related for women, and these figures were 55% and 3% for men. The study reports that vigorous-intensity PA is low, and recreation time is minimal. Routine PA, especially for women and people with low education levels, should be encouraged to increase PA to manage hypertension.

Lowering blood pressure by changing lifestyle through a motivational education program: a cluster randomized controlled trial study protocol

BACKGROUND

High blood pressure is an independent risk factor of cardiovascular disease (CVD) and is a major cause of disability and death. Managing a healthy lifestyle has been shown to reduce blood pressure and improve health outcomes. We aim to investigate the effectiveness of a lifestyle modification intervention program for lowering blood pressure in a rural area of Bangladesh.

METHODS

A single-center cluster randomized controlled trial (RCT). The study will be conducted for 6 months, a total of 300 participants of age 30 to 75 years with 150 adults in each of the intervention and the control arms. The intervention arm will involve the delivery of a blended learning education program on lifestyle changes for the management of high blood pressure. The education program comprises evidence-based information with pictures, fact sheets, and published literature about the effects of high blood pressure on CVD development, increased physical activity, and the role of a healthy diet in blood pressure management. The control group involves providing information booklets and general advice at the baseline data collection point. The primary outcome will be the absolute difference in clinic SBP and DBP. Secondary outcomes include the difference in the percentage of people adopting regular exercise habits, cessation of smoking and reducing sodium chloride intake, health literacy of all participants, and the perceived barriers and enablers to adopt behavior changes by collecting qualitative data. Analyses will include analysis of covariance to report the mean difference in blood pressure between the control and the intervention group and the difference in change in blood pressure due to the intervention.

DISCUSSION

The study will assess the effects of physical activity and lifestyle modification in controlling high blood pressure. This study will develop new evidence as to whether a simple lifestyle program implemented in a rural region of a low- and middle-income country will improve blood pressure parameters for people with different chronic diseases by engaging community people.

Assessment of Knowledge and Attitude of Cataract and Their Associated Factors Among Adults in Arba Minch Zuria Woreda, Southern Ethiopia

Background

Cataract is the major cause of reversible blindness and visual impairment in developing countries. It has been assumed that there is poor access to information related to the cause, prevention, and treatment of cataract in developing countries. There is also a paucity of data on knowledge and attitude towards cataract in Ethiopia.

Purpose

This study aimed to assess the knowledge and attitude of cataract and their associated factors among adults in Arba Minch Zuria Woreda, Southern Ethiopia.

Patients and Methods

A community-based cross-sectional study was conducted among 623 adults from February 6 to April 16, 2020. The study participants were selected by the multi-stage sampling technique. Data were collected with a pre-tested structured questionnaire by using face-to-face interviews. The data were entered into Epi info version 7.2 and exported to SPSS version 23 for analysis. The level of statistical significance was set at a p-value less than 0.05 in multivariable logistic regression.

Results

Among 623 total participants, 54.9% of them had good knowledge about cataract, while 37.9% of them had favorable attitude about cataract. Inability to read and write (AOR=0.104, 95% CI: 0.042–0.258), primary school educational level (AOR=0.208, 95% CI: 0.091–0.478), secondary school educational level (AOR=0.199, 95% CI: 0.088–0.451), earning average monthly income 350–820 Ethiopian birr (AOR=2.364, 95% CI: 1.277–4.373), not having previous eye examination (AOR=0.605, 95% CI: 0.425–0.861) and unavailability of eye clinic (AOR=0.65, 95% CI: 0.446–0.945) were significantly associated with knowledge of cataract. No history of cataract (AOR=0.257, 95% CI: 0.157–0.418) was significantly associated with attitude towards cataract.

Conclusion

Significant portion of participants had poor knowledge and an unfavorable attitude towards a cataract. So, it is recommended that stakeholders in different hierarchies need to exert efforts on creating awareness about cataract by considering the education level of the community. Moreover, attention should be given to the availability and accessibility of the primary eye care unit.

Awareness and knowledge about glaucoma among patients visiting the screening clinic in Jeddah Eye Hospital, Saudi Arabia

AIM

To explore levels and determinants of awareness and knowledge about glaucoma among patients.

METHODS

This was a cross-sectional study that included adult patients from October to the end of December 2018. A semi-structured questionnaire was designed by the researchers to measure the levels of awareness and knowledge about 18 basic information about glaucoma. The sheet was divided into 4 domains: types of glaucoma, risk factors, clinical features, and management. A knowledge score (KS, range=0-18) was calculated, with higher scores indicating higher levels.

RESULTS

A total of 383 patients responded to the questionnaire, 61.9% males, mean±SD age was 38.5±12.94 years old, and 61.6% had a university degree or higher. Of them, 6.3% and 23.2% reported personal and family history of glaucoma, respectively. The most frequently reported source of information about glaucoma was another person with glaucoma (28.2%), followed by physicians (24.8%) and TV (19.6%). Knowledge by item ranged from 3.1% to 82.5% correctness rate, while KS showed mean=5.91 and median=5; and reliability testing of the knowledge scale showed Cronbach's alpha=0.782. Higher KS were found among respondents with higher educational level (P=0.036), diabetes history (P=0.025), and personal (P<0.001) and family (P<0.001) history of glaucoma.

CONCLUSION

This study reveals low awareness and knowledge levels about glaucoma among the attendees of a local eye care hospital, where several misconceptions about disease risk factors, clinical features, and management are identified.

Public Awareness of Common Eye Diseases and the Role of Pharmacists in Raising This Awareness in Saudi Arabia: A Cross-Sectional Study

Knowledge of common eye disorders and their prevention and treatment can play an essential role in reducing the visual impairment burden. A cross-sectional, questionnaire-based study was conducted from 15 November 2020 to 15 January 2021 to estimate the knowledge and awareness about common eye problems and their possible risk factors among the general population of the Hail Region, Saudi Arabia. The study also investigated the participants’ sources of information about eye diseases. Participants from various areas of the Hail Region were randomly selected. There were four parts in the questionnaire based upon the general awareness about the common eye diseases, participants’ knowledge and awareness of risk factors associated with eye disorders, awareness of treatment and prevention of various eye disorders, and the participants’ sources of information about ocular diseases. The questionnaire was distributed to the participants by direct contact with them at eye clinics, hospitals, malls, and markets. The number of participants in the survey was 400 people, 53.8% males and 46.3% females. Cataracts were known to 31% of the participants, 43% knew about glaucoma, 66% knew about dry eyes, and 44% knew about diabetic retinopathy. Overall, 46% of the participants knew about eye problems, and the male participants had better knowledge about eye problems than the female ones. The primary sources of information about the common eye diseases were pharmacists (43.3%), family physicians (40.3%), the Internet (37.3%), the community (37.3%), television and radio (9.3%), and books/ brochures (9.5%). In the Hail Region, the general public carries a moderate awareness of preventable vision-threatening ocular disorders. However, the awareness of cataracts and glaucoma was low. The gaps in awareness can be overcome by public health promotion. In offering information about eye conditions to the general public, pharmacists may play a crucial role.

Mobile health intervention for promotion of eye health literacy

PURPOSE

Improving eye health awareness in the underserved population is a universal eye health priority. The ubiquity of cell phones and internet usage provides new and innovative opportunities for health promotion. This study evaluated the effect of mobile health intervention (text message link) to promote eye health literacy (EHL) of priority ocular morbidities.

METHODS

This study was an intervention evaluation and employed a two-armed pre-test post-test approach. Baseline assessment on EHL was performed on 424 university students. Participants were categorised into intervention and control groups, using the 1:1 allocation ratio. The intervention and control group received a text message alone and text message with a link, respectively. EHL was assessed via a self-administered questionnaire. The primary outcome measures were changes in EHL scores between baseline and one month post-intervention. Descriptive analysis was performed to assess the cost-effectiveness of the intervention.

RESULTS

With low attrition and a response rate of 95.6%, 409 responses were eligible for analysis. The mean age of the participants (49.4% males and 50.6% of females) was 19.9±1.68 years. Baseline EHL scores were low, and there was no correlation with a demographic profile (all p<0.05, CI 95%). The demographic characteristics were similar between the two groups (for all, P <0.05, CI 95%) at baseline. The EHL scores improved in both groups between the pre-and post-test assessment; however, improvements were statistically significant only in the control group. The one-month post-intervention EHL scores were also higher in the intervention group compared to the control (p≤0.001, CI 95% for all). The total cost incurred for the intervention used was 11.5 USD.

CONCLUSION

Text message link demonstrated effectiveness for improving the EHL scores; the low baseline EHL scores substantially improved with intervention. The text message link intervention is a cost-effective method and could be considered in advocating for eye health in developing countries, particularly during global emergencies.

Knowledge, Attitudes, and Practices about Trachoma in Rural Communities of Tigray Region, Northern Ethiopia: Implications for Prevention and Control

Background

Trachoma is a neglected tropical disease which is the leading infectious cause of blindness in the world. Trachoma is one of the major health problems in Tigray Region, Northern Ethiopia. However, knowledge, attitudes, and practices about trachoma are not yet studied in depth. The objective of the study was to assess knowledge, attitudes, and practices on trachoma and its associated factors among rural communities in two districts of Tigay Region, Northern Ethiopia.

Methods

A cross-sectional study was conducted in two districts of Tigray Region, Northern Ethiopia, from May 7–24, 2017. Data were collected on paper based, were entered into Epi Info version 3.5.1, and then exported to SPSS version 21 for analysis. Logistic regression analysis was done to identify factors associated with knowledge, attitudes, and practices.

Results

In this study, a total of 194 respondents were included. The overall level of good knowledge, attitudes, and practices on trachoma was 51%, 49.5%, and 35.6%, respectively. Having ever received health education was significantly associated with good knowledge (adjusted odds ratio (AOR) = 4.10; 95% confidence interval (CI): 1.91–8.79) and attitudes (AOR = 2.10; 95% CI: 1.02–4.25). Moreover, good knowledge was associated with good practices on trachoma prevention and control (AOR = 2.86; 95% CI: 1.46–5.62).

Conclusion

Our study implies that areas with high burden of trachoma need to improve communities' knowledge, attitudes, and practices towards trachoma prevention and control in order to eliminate trachoma as a public health problem. Therefore, health education focused on SAFE strategy should be provided to increase knowledge and changing attitudes that contribute for good practices towards trachoma prevention and control among communities.

An assessment of awareness of mental health conditions and its association with socio-demographic characteristics: a cross-sectional study in a rural district in Bangladesh

BACKGROUND

To assess the level of awareness, knowledge and help-seeking attitudes and behaviours in relation to mental health conditions (MHCs) and associations with socio-demographic characteristics of a rural district of Bangladesh.

METHODS

We recruited 2425 adult samples (18-90 years) from a Cross-sectional study in Narial district of Bangladesh. Data on awareness, knowledge, help-seeking attitudes and practice in relation to six MHCs were collected. The MHCs were classified as common (depression, anxiety and drug addiction), and severe (psychosis, dementia and bipolar disorder). Associations of MHCs with socio-demographic characteristics were assessed using Chi-square tests. Rasch analysis was performed to transform the latent attribute (awareness) of MHCs from ordinal to interval scale. Multiple regression analysis was performed to determine how the socio-demographic characteristics contribute to the combined awareness score of MHCs.

RESULTS

Of 2425 participants, 17 (0.7%) were cognizant of all the awareness construct of MHCs, and 1365 (56.28%) were not aware of any of MHCs. The prevalence of awareness of MHCs such as depression (8.5%), anxiety (6.2%), psychosis (3.5%), and bipolar disorder (3.3%), was found to be very low. Awareness was significantly lower in older adults, and in women. Higher levels of education (β 1.77, 95% confidence interval (CI): 1.58-1.97) associated with common MHCs and (β 0.81, 95% CI: 0.67-0.95) those associated with severe MHCs contributed significantly to increased awareness as opposed to having no or primary level of education. Availability of sufficient funds when applied to common MHCs (β 0.43, 95% CI: 0.26-0.61) and severe MHCs (β 0.25, 95% CI: 0.13-0.38) appeared to be more effective in boosting awareness compared to unstable financial situations. Almost 100% of the participants who were aware of the MHCs demonstrated positive attitudes towards seeking medical or psychological counselling.

CONCLUSIONS

Awareness of MHCs appeared to be very limited. However, knowledgeable participants were found to be very receptive to medical or psychological counselling. For improving awareness of MHCs need to conduct various intervention programs in particular those campaigns that focus on women, older adults, low SES and people up to the primary levels of education.

Factors Associated with Knowledge, Attitude and Practices of Common Eye Diseases in General Population: A Multicenter Cross-Sectional Study from Pakistan

High prevalence of blindness coupled with low public awareness of eye diseases is a severe problem in Pakistan. The objective of this study was to evaluate the awareness, attitude and practices related to common ocular problems and eye care use among general population of Punjab, Pakistan. Data were collected cross-sectionally, using random selection of participants from five districts of Punjab, Pakistan. A pre-tested questionnaire was used to collect the data from January to March 2017. The ordinal data were converted to interval--based data by Rasch analysis, which is termed as "knowledge score" and ranges from -3 to +3. Descriptive statistics, linear regression, binary logistic regression and chi square analysis were performed to evaluate the data. Of the 2073 people contacted, 96.4% (2019) responded the interviewer. The mean (SD) age was 39.9 (11.4) years, majority were males (64.8%) and only 3.1% were illiterate. The majority (68.1%) of respondents were aware that blindness can be prevented and are least aware of age-related macular degradation (31.4%). Multivariate analysis to knowledge scores demonstrated that male gender (β = 0.53 95%CI = 0.39, 0.66, p < 0.001), higher education (β = 0.31 95%CI = 0.25, 0.37, p < 0.001) were significantly associated with knowledge score. Eighty-two percent of our respondents had a positive attitude towards health-seeking behavior and those who had adequate income on most of occasions were 1.82 (AOR = 1.82 95%CI = 1.26, 2.62 p = 0.001) times more prone towards health-seeking behavior than those who had insufficient income. Out of all respondents, 21.5% had an eye examination at least once a year and this frequency was significantly higher in lower age, females, high education and high Socio Economic Status level (p < 0.05). Among the general population of Pakistan, awareness about prevention of blindness and refractive error was optimum, while awareness of blindness causing eye conditions, like age-related macular degradation was low. Intensive improvements in the health literacy and public interventions-specifically in old age people, males and respondents with lower education-are urgently needed.

Knowledge about cataract and associated factors among adults in Gondar town, northwest Ethiopia

Purpose

The aim of this study was to assess knowledge regarding cataract and associated factors among adults in Gondar town Northwest Ethiopia.

Methods

A community-based cross-sectional study was conducted on 836 adults age ≥18years, using multi-stage systematic random sampling technique, in Gondar town Northwest Ethiopia from April 15-May 7, 2017. Data were collected using pre-tested structured questionnaires through face to face interview. The collected data was entered to Epi info version 7 and analyzed using SPSS version 20. Binary logistic regression was used to identify associated factors. Those variables with p-value <0.05 and confidence interval ≠ 1 in multivariable logistic regression were considered as statistically significant factors for knowledge regarding cataract.

Result

Among 845 eligible adults, 98.9% (836) of them were fully participated. The median age of participants was 28 years with an interquartile range of 17 years. Of the total participants, 67.2% (562) of them had awareness about cataract [95% CI, 63.8–70.2]. Among 562 participants, 61.7% of them had good knowledge about cataract [95% CI, 57.5–66.00]. It was also found that higher level of education [AOR = 2.86, 95%CI: 1.37–5.96], higher family monthly income [AOR = 1.92, 95%CI: 1.03–3.57], having previous eye examination [AOR = 1.53, 95% CI: 1.02–2.31] and positive family history of cataract [AOR = 1.76, 95%CI: 1.03–3.01] were positively associated with good knowledge.

Conclusion

Significant portion of the participants had good knowledge about cataract, which was positively associated with higher level of education, higher family monthly income, presence of previous eye examination and positive family history of cataract. However, significant knowledge gap regarding the risk factors and prevention strategies was recognized. Hence, it might be logical to pay special attention in prospering knowledge on how to prevent the occurrence of the disease.

Incidence and Risk Factors for Blindness in Adults With Diabetes: The Israeli National Diabetes Registry (INDR)

PURPOSE

To estimate the 3-year incidence of blindness among diabetes patients aged ≥18 years; to compare blindness incidence rates of persons with and without diabetes; and to investigate risk factors associated with diabetic retinopathy (DR), age-related macular degeneration (ARMD), glaucoma, and cataract-related blindness.

DESIGN

Cohort study.

METHODS

The Israeli National Diabetes Registry for 2012 was cross-linked with the database of blindness certifications obtained from the National Registry of the Blind. Blindness was defined as the receipt of an official certificate of blindness (a visual acuity of 3/60 or worse, or a visual field loss of <20 degrees in the better eye.) Incidence rates of blindness, overall and by main cause of blindness, were calculated for the years 2013-2015. Standardized morbidity ratios (SMRs) for 2013 were calculated, using the nondiabetic population as a reference. A multinomial logistic model was used to identify covariates associated with the incidence of blindness by main cause of blindness.

RESULTS

The 3-year incidence rates were 31.0 and 8.4 per 10 000 for overall and DR-related blindness, respectively. The SMR for overall blindness in people with diabetes was significantly higher than in the general nondiabetic population (1.39; 95% confidence interval: 1.27-1.53); however, the SMRs for ARMD, glaucoma, and cataract were not statistically significant. Poor metabolic control, insulin treatment, long diabetes duration, and chronic kidney disease were associated with DR-related blindness. Low socioeconomic status (SES) was associated with both cataract and DR-related blindness.

CONCLUSIONS

Optimum metabolic control of diabetes is important for prevention of DR-related blindness. SES-related disparities in blindness risk should be explored and reduced by directing efforts to provide appropriate treatment for all diabetic patients in order to prevent unnecessary blindness.

Sociodemographic Differences in Smoking Knowledge in Malaysia

The objective of the present study is to examine the sociodemographic determinants of amount of smoking knowledge in Malaysia. Data are obtained from the Global Adult Tobacco Survey (GATS). The GATS uses a multistage stratified sampling. A total of 4,153 respondents are used for analyses. The effects of sociodemographic factors on smoking knowledge are examined using a negative binomial regression. Age, wealth index, education, ethnicity, house locality, and smoking behavior are significantly associated with smoking knowledge. In particular, there are negative relationships between smoking knowledge and higher wealth index, less-educated individuals, Chinese, rural dwellers, and smokers. The present study concludes that sociodemographic factors play an important role in determining smoking knowledge. Hence, as an intervention measure directed toward improving the knowledge of smoking among Malaysian population, effective policies should pay special attention to individuals who are likely to have poor information on smoking.

Health awareness, lifestyle and dietary behavior of university students in the northeast part of Bangladesh

INTRODUCTION

University students generally face a variety of challenges. During this period of life, they practice some unhealthy eating patterns and lifestyles. Therefore, we aimed to assess the health awareness status of university students from the northeast part of Bangladesh and to evaluate its associated factors.

METHODS

We conducted a cross-sectional study using a stratified random sampling among public and private university students from the northeast region of Bangladesh and interviewed 1143 students. We used a self-reported questionnaire, including questions related to awareness status, lifestyle practice, dietary habit and socio-demographic factors. To assess students' health awareness status and its association with their lifestyle practices and socio-demographic factors, we used logistic regression models.

RESULTS

The majority (61%) of the students were not aware of better health status and their dietary habits were not adequate. Smokers [odds ratio (OR): 0.66; 95% confidence interval (CI): 0.44, 0.99] were less likely to be aware of better health status. The participants who thought that they were leading a healthy lifestyle were less likely (OR: 0.71; CI: 0.56, 0.92) to be aware. Moreover, frequency of participating in sports and the psychological factors related to eating behaviors were significantly (p < 0.05) associated with health awareness status.

CONCLUSION

Our study findings may help to create a foundation for possible interventional programs on health awareness and nutritional education to improve the health awareness status and dietary behavior of university students. To prevent students from poor eating habits while feeling happy, effective programs (e.g. seminars, projects and media campaigns) should be held, which may include enhancing healthy and recommended amounts of food consumption.

Factors associated with participation in a diabetic retinopathy screening program in a rural district in Bangladesh

AIM

Diabetic retinopathy (DR) screening is one of the keys in successful diabetes care, but the participation in DR screening is sub-optimal. This study aims to assess the factors associated with participation in a DR screening program in a rural district of Bangladesh.

METHOD

213 persons with diabetes identified in a population-based assessment of over 3000 persons ≥ 40 years were offered free of cost screening for DR. Awareness, attitudes and practice about diabetes and common eye diseases along with socio-demographic factors were assessed.

RESULTS

68 (32%) patients participated in the screening program. After multivariate adjustment, awareness related to diabetes causes eye disease (odds ratio (OR) 8.47, 95% confidence interval (CI) 3.95-18.18), awareness of DR (OR 5.15, 95% CI 1.89-14.01) and awareness of the possibility to prevent DR-related vision loss (OR 3.15, 95% CI 1.53-6.51) were associated with higher proportion of participation. Lack of confidence upon skills of ophthalmic assistants and fear of complications were barriers but socio-economic condition was not a barrier in attending the screening program.

CONCLUSIONS

The major factor associated with participation in DR screening is diabetes-related health literacy in rural Bangladesh. Public health promotion program should be designed to provide health education to increase participation in the screening program.

Factors associated with second-hand smoke awareness in Malaysia

Background:

The proportion of people exposed to second-hand smoke increases dramatically with a sharp increase in the prevalence of smoking. It is expected that awareness of the effect of second-hand smoke plays an important role in curbing smoking.

Objectives:

The objective of this study is to examine factors affecting awareness of second-hand smoke in Malaysia.

Methods:

Nationally representative data, covering a large sample size (4153 respondents) and collected based on multistage sampling, are used. Multiple logistic regression is employed to analyse the effects of demographic and lifestyle variables on the likelihood of being aware of second-hand smoke.

Results:

Results show that older people are less likely to be aware of second-hand smoke than youngsters and that less-educated individuals are less likely to be aware of second-hand smoke than well-educated individuals. Significant relationships are found between second-hand smoke awareness and wealth index, ethnicity and smoking behaviour.

Conclusion:

Demographic profiles should be considered when drawing up policies aimed at improving awareness of second-hand smoke among adults. The government needs to focus more on older people, wealthy individuals, less-educated individuals, Chinese individuals and smokers if a successful policy is to be implemented.

Investigation of time to first presentation and extrahospital factors in the treatment of neovascular age-related macular degeneration: a retrospective cross-sectional study

OBJECTIVES

To assess the time from symptom onset to treatment for neovascular age-related macular degeneration (nvAMD) and to measure the awareness of AMD in Southeast Scotland.

DESIGN

Retrospective cross-sectional study.

SETTING

Secondary care, Southeast of Scotland.

METHODS

Patients treated with intravitreal therapy (IVT) for nvAMD in Southeast Scotland between 2013 and 2015 were identified using a treatment register. Notes were retrospectively reviewed. We measured time from: (A) symptom onset to first presentation at primary care, (B) referral to ophthalmic clinic appointment and (C) ophthalmic clinic appointment to first IVT treatment. To investigate AMD awareness, we performed a cluster random sample survey of patients visiting non-AMD ophthalmic clinics using a previously validated 12-item questionnaire.

RESULTS

195 patients (mean age 78 years) were included in the study. The mean delays between the different stages-A, B and C-were 54.2 (95% CI ±13), 28.2 (95% CI ±4.0) and 31.5 (95% CI ±3.6) days, respectively. There was an additional mean delay of 7.5 (95% CI ±1.6) days when patients were indirectly referred by optometrists via general practitioners (P<0.05). 140 patients (mean age 78) participated in the awareness survey; 62.1% reported being 'aware' of AMD but only 37.3% described AMD symptoms correctly.

CONCLUSIONS

There was a significant delay at every step of the nvAMD care pathway. The causes for this were multifactorial and included delays in first presentation to a healthcare provider, referral from primary care and initiation of secondary care treatment. Our data are likely to underestimate prehospital delays as a large number of cases are likely to have undefined symptoms and onset. We also identified suboptimal awareness of AMD which could account for a substantial delay in presentation from symptom onset. These findings highlight the need to address AMD awareness and the need for urgent treatment to prevent avoidable vision loss resulting from nvAMD.

Awareness and eye health-seeking practices for cataract among urban slum population of Delhi: The North India eye disease awareness study

Purpose:

The objective of the study was to assess the awareness and health-seeking practices related to cataract in urban slums of Delhi.

Methods:

This study design was a population-based cross-sectional study. Participants aged 18–60 years were recruited from randomly selected five slums of South Delhi. They were interviewed using a semi-structured interview schedule on awareness and eye health-seeking practices related to cataract. The practices were recorded if the respondents themselves or any other member of the family was diagnosed with cataract in previous 2 years.

Results:

A total of 1552 respondents participated in the study, of which, 89.9% had heard of cataract but only (42%) were aware of any symptom of cataract. The common symptoms of cataract reported by the participants were white opacity in eyes (25.9%) and loss of vision (20.6%). Surgery as a treatment of cataract was known to only 559 (40.1%) participants. Awareness about surgery as treatment of cataract was significantly higher among people aged 45–60 years (adjusted odds ratio = 2.89, 95% confidence interval = 2.11–3.97) and in educated people (adjusted OR = 3.69 95% CI = 2.37–5.73). Out of 84 respondents who had been diagnosed with cataract, the health-seeking practices were observed by 70 (83.3%) participants. Among them, 51 (72.9%) had undergone surgery and another 19 (27.1%) had been advised to wait for surgery. Most of the operated patients 48 (94.1%) attended the postoperative follow-up.

Conclusion:

The study findings suggest the majority of participants have heard of cataract, but there is low awareness of its symptoms and treatment, and good eye health-seeking practices observed for cataract in urban slum population. Gaps in awareness observed can be filled up by implementing proper eye health education programs.

Multiple deprivation, vision loss, and ophthalmic disease in adults: global perspectives

The association between socioeconomic position and morbidity and mortality has long been recognized. We evaluate the evidence for an association between multiple aspects of deprivation and ocular health in a global context. This is a systematic review of studies that evaluated deprivation in the adult population in the context of the major acquired causes of visual loss such as cataract, diabetic eye disease, glaucoma, age-related macular degeneration, and ocular trauma. The search strategy identified relevant studies reported between 1946 and August 2016, with randomized control trials, case-control, cohort, and cross-sectional study designs being selected for inclusion. The studies identified in this review from across the world demonstrate the extent to which the common themes such as low educational attainment and low income may be associated with increased incidence of various sight-threatening conditions and may adversely affect access to specialist assessment and delivery of treatment. Health inequality may always persist, but an increased recognition of the importance of the various impacts of deprivation may empower policy makers to target limited resources to the most vulnerable groups in order to deliver the greatest benefit.

Public awareness of common eye diseases in Jordan

BACKGROUND

Cataract, glaucoma, diabetic retinopathy and dry eye disease are common with high prevalence in Jordan. This study aims to assess the awareness of these ocular diseases among Jordanian population.

METHOD

A self-designed questionnaire was developed in Arabic and used to interview people in different provinces of Jordan. Socio-demographic data e.g. age, gender and level of education was reported. Public awareness of four ocular diseases; cataract, glaucoma, diabetic retinopathy (DR) and dry eye disease (DED) was assessed. Questions about familiarity with the diseases, familiarity with their risk factors and participants' source of knowledge were asked. Moreover, awareness of the effect of these disease on the eye whether they are blinding, preventable, treatable and/or the vision is back to normal following treatment was also assessed.

RESULTS

A total of 802 participants (232 males and 570 females) completed the questionnaire. The average age (± standard deviation) of the study participants was 28 ± 11.6 (range 18 to 80 years old). Awareness of cataract, glaucoma, DR and DED was reported by 31%, 38%, 37% and 52% of the study population, respectively. Family/relatives/friends and mass media appeared to be the most common sources of knowledge. Age and level of education of the participants were significantly associated with the level of disease awareness.

CONCLUSION

This work shows that the level of awareness of the four ocular diseases among Jordanians is good and compares with many reports in the developed and developing countries. Familiarity and knowledge about ocular diseases is essential as it would increase the chance of the subject being tested and thus diagnosed early enough if any problem occurred. Better understanding of the disease would encourage subjects to seek medical care sooner which in turn would prevent visual impairment. Therefore, awareness campaigns should be made to target unaware population.

Ocular knowledge and practice among type 2 diabetic patients in a tertiary care hospital in Bangladesh

Background and aims

Diabetes mellitus is likely to have a major effect on vision, and adequate knowledge of its ocular manifestations is of substantial importance to diabetic patients. The study aimed to assess the ocular knowledge and practices among Type 2 diabetic patients of Bangladesh.

Methods

This cross-sectional study included 122 diabetic patients from the outpatient department (OPD) of the apex diabetic healthcare hospital of the country under the sponsorship of the Diabetic Association of Bangladesh (BIRDEM). A questionnaire was used for collecting data on knowledge on and practices relating to diabetes mellitus with particular emphasis on ocular issues. A predefined score was used for categorizing levels of knowledge and practices as poor, average, and good.

Results

Of the 122 respondents, 63%, 55%, 40%, 44%, and 30% reported, blindness, retinopathy, cataracts, glaucoma, and double vision respectively, as complications of diabetes mellitus. About 50% were aware of the need for eye screening for people with the complications. Only 8% monitored their blood glucose levels daily, 15% monitored weekly, and 10% reported checking their blood pressure daily and 43% took their medications as prescribed. The level of diabetic knowledge was poor, moderate and good, respectively, among 24%, 56%, and 20% of the respondents, whereas the practice standards showed that 47%, 31%, and 22% had poor, average, and good levels respectively. The knowledge score was significantly associated with the practice score (r = 0.460, p = 0.001).

Conclusion

The results indicate that the ocular knowledge and practices among diabetic patients attending a tertiary-care hospital in Bangladesh is average. Health and eye-care practitioners need to expand diabetic health education and promotion among diabetic patients.

Awareness and practices regarding eye diseases among patients with diabetes: a cross sectional analysis of the CoDiab-VD cohort

BACKGROUND

The increasing prevalence of diabetes is leading to a rise of eye diseases, augmenting the risk of sight-threatening complications. The aim of this study was to evaluate prevalence, awareness and practices regarding eye diseases among patients with diabetes in the canton of Vaud, Switzerland.

METHODS

A cohort of 323 patients with diabetes completed a self-administered questionnaire assessing prevalence, awareness and practices regarding eye diseases, besides health status and quality of care measures. Descriptive analyses followed by exploratory subgroup analyses and linear regressions were performed to investigate factors associated with awareness and practices.

RESULTS

While diabetic retinopathy was reported by 40.9% of patients with type 1 diabetes and 9.8% of patients with type 2 diabetes, 35.8% and 12.6% of all participants reported cataract and glaucoma, respectively. Awareness that diabetes could damage the eyes was reported by almost all participants; the majority was also aware of the importance of glycemic control and regular eye examination in preventing eye diseases. In contrast, only 70.5% of participants underwent an eye examination by an ophthalmologist during the past year. Eye examination was associated with better patients' awareness. Barriers mentioned by patients revealed a lack of knowledge about screening guidelines, in particular regarding the preventive nature of eye examinations.

CONCLUSIONS

Despite high levels of awareness regarding diabetic eye diseases, a significant proportion of patients with diabetes did not report annual eye examination. Both healthcare strategic efforts targeting the promotion of regular eye examination and initiatives aiming at improving knowledge of screening guidelines should be encouraged.

Psychological distress and quality of life: rationale and protocol of a prospective cohort study in a rural district in Bangaladesh

INTRODUCTION

A significant proportion of the global burden of disease has been attributed to mental and behavioural disorders. People with mental disorders (MDs) have lower levels of health-related quality of life than those without MDs. Several studies have shown that in low-resource countries, a range of social determinants including poor health literacy is critical in the epidemiological transition of disease outcome. There is a lack of evidence of MDs literacy, the prevalence and risk factors of common mental health conditions, or any validated instruments to measure psychological distress or evaluate the quality of life in rural areas of Bangladesh.

AIMS

The aims of this study are: (1) report the awareness, knowledge, attitudes and practice (KAP) of MDs; (2) estimate the prevalence of and risk factors for psychological distress; (3) measure association of psychological distress and other socio-demographic factors with quality of life and (4) test the feasibility to use Kessler 10-item (K10) and WHO Quality Of Life-BREF (WHOQOL-BREF) questionnaires in rural Bangladesh for measuring psychological distress and quality of life.

METHODS AND ANALYSIS

A sample of 1500 adults aged 18-59 years and 1200 older adults aged 60-90 years will be interviewed from a multistage cluster random sample. Each participant will go through a face-to-face interview to assess their awareness and KAP of MDs. Information about the participant's sociodemographic and socioeconomic status will be collected along with the psychological distress (K10) and quality of life (WHOQOL-BREF) questionnaires. Internal consistency, validity, reliability and item discrimination of K10 and WHOQOL-BREF instruments will be determined by using Rasch analysis and regression techniques.

ETHICS AND DISSEMINATION

Human Ethics Approval was received from the Swinburne University of Technology Human Ethics Committee. Results of this research will be disseminated via scientific forums including peer-reviewed publications and presentations at national and international conferences.

Public Awareness regarding Common Eye Diseases among Saudi Adults in Riyadh City: A Quantitative Study

Aim

The current study aimed to evaluate the knowledge of eye disease and awareness of eye care among the Saudi adults and to explore existing eye-related misconceptions in the community.

Methods

A cross-sectional study was conducted in Riyadh city during May and June 2016. A self-administered anonymous online questionnaire was used to explore the most common misconceptions related to eye diseases and eye care.

Results

Out of 1000 individuals, only 711 (71.1%) participant responses were received. The participants' acceptable knowledge (score ≥50%) was high about the eye problem in diabetes (88.6%), ocular trauma (81.2%), and other general eye diseases (91.3%), whereas low about refractive errors (63%), pediatric eye problems (51.5%), and glaucoma (14.8%). The variation in knowledge about specific ocular morbidities was significant (p < 0.001). The majority of participants reported sources of information about the common eye diseases and eye care encountered from the community, internet-based resources, and social media.

Conclusions

The majority of the participants had awareness about the common eye diseases, whereas low percentage of participant's awareness about specific condition of eye diseases. Public eye health awareness should be more focused on social media and the internet to be able to cover the younger individuals of the community.

Accuracy and reliability of retinal photo grading for diabetic retinopathy: Remote graders from a developing country and standard retinal photo grader in Australia

Background

To evaluate the accuracy and reliability of fundus retinal photos graded by local graders in Bangladesh with those graded by an expert at the Centre for Eye Research Australia (CERA) in the context of mass scale diabetic retinopathy (DR) screening in Bangladesh.

Methods

A population-based cross-sectional study of 3,104 adults identified 213 (7.2%) eligible patients with diabetes of age ≥ 40 years in 2012–2013. Retinal photographs were collected using a non-mydriatic digital fundus retinal camera and a two-field imaging protocol. The photos were graded by two remote graders (G1 and G2) who were trained by a retinal specialist (RS) in Bangladesh, by the RS himself, and by a Centre for Eye Research Australia (CERA) grader. The local graders up skilled their grading ability by comparing 30% of the photos graded by the CERA grader with their own grades. Learning from that exercise was applied to the remaining 70% of photos, which were re-graded. Reliability and accuracy of grading amongst the graders were reported using cross tabulation, inter- and intra-grader reliability, and with sensitivity and specificity.

Results

Of 122 eyes from 61 patients, the mild (R1) DR was estimated to be 14 to 25%, pre-proliferative (R2) DR 4–8%, and proliferative (R3) DR 0.8 to 1.6%, whereas 25%, 8%, 18%, and 15% were found to be ungradable by CERA, RS, G1, and G2, respectively. Of 8 (6.6%) eyes identified as R2 by the CERA grader, 5 (63%), 3 (38%) and 3 (38%) were correctly classified as R2, whereas the rest were classified either as R1 or R3 but none were classified as no DR (R0) or ungradable by the RS, G1 and G2, respectively. After getting experience reviewing the 30% test set graded by the CERA grader, the local graders graded moderate and severe DR with 100% accuracy. After excluding ungradable photos, the sensitivity (specificity) relative to the CERA grader was 82% (88%) before and 80% (93%) after training for G1 and 56% (87%) before and 77% (90%) after training for G2. In case of maculopathy, the CERA grader reported 11.2% eyes with maculopathy, which included 100% of the 4.9% by RS, 6.6% by G1, and 7.4% by G2.

Conclusions

Local graders in Bangladesh are able to grade retinal photos with high accuracy if the DR is at least of a moderate level. With appropriate training and experience, local graders have the ability to contribute significantly to the grading of millions of retinal photos, which required grading in resource- poor countries.

Awareness of Age-related Macular Degeneration and Its Risk Factors among Beijing Residents in China

BACKGROUND

Age-related macular degeneration (AMD) is a major cause of irreversible blindness, and awareness of this disease is important in the prevention of blindness. However, lack of public awareness of AMD was shown in previous studies, and there was no report of AMD awareness in the Mainland of China. Therefore, the aim of our study was to assess the awareness of AMD and its risk factors among Beijing residents in China.

METHODS

A cross-sectional, computer-assisted, telephone investigation was conducted to measure the awareness of AMD among Beijing residents. All the contacts of potential respondents were randomly generated by computer. Only those above 18 years of age and willing to participate in the study were included. The questionnaire for the study was modified from the AMD Alliance International Global Report. Pearson's Chi-square test and binary logistic regression analysis were used to identify the factors that affected the knowledge of AMD.

RESULTS

Among 385 Beijing residents who agreed to participate, the awareness of AMD was 6.8%, far below than that of cataract and glaucoma. Participants who were above 30 years of age (odds ratio [OR] 6.17, confidence interval [CI] 1.44-26.57), with experience of health-related work (OR 8.11, CI 3.25-20.27), and whose relatives/friends or themselves suffering from AMD (OR 32.18, CI 11.29-91.68) had better AMD awareness. Among those familiar with AMD, only 35% of them identified smoking as a risk factor, and only 23.1% of the residents believed that smoking could lead to blindness.

CONCLUSIONS

The sample of Chinese population had limited knowledge of AMD. Educational programs need to be carried out to raise public awareness of AMD.

Factors Associated with Disability in Rural Bangladesh: Bangladesh Population-Based Diabetes and Eye Study (BPDES)

BACKGROUND

To assess factors associated with disability in a rural district of Bangladesh.

METHODS

Using a population-based systematic sampling technique, data were collected from 3104 adults aged ≥ 30 years from the Banshgram union of Narail district. Data collected included an interviewer administered questionnaire to report physical disabilities including impairment that prevents engagement with paid work, visual, hearing, and mobility as well as mental disabilities. Socio-demographic and anthropometric factors including educational attainment and body mass index, as well as clinical factors such as blood pressure, and fasting blood glucose were also collected. Binary and multinomial logistic regression techniques were used to explore the association of various socio-demographic and clinical factors with disability.

RESULTS

The mean (SD), minimum and maximum ages of the participants were 51 (12), 30 and 89 years. Of total participants, 65% were female. The prevalence of disability varied from 29.1% for visual impairment (highest) to 16.5% for hearing, 14.7% for movement difficulties and 1.6% (lowest) for any other disability that prevented engagement with paid work. Overall, the prevalence of a single disability was 28.6% and that of two or more disabilities was 14.7%. Older age, gender (female), lower socio-economic status (SES), and hypertension were associated with a higher prevalence of most of the disability components. The prevalence of hearing problems (24.5% vs. 13.3%, p<0.001) and movement difficulties (24.9% vs. 13.0%, p<0.001) was significantly higher among lower-income participants than their higher-income counterparts after controlling for age. Prevalence of visual impairment (54.6% vs. 9.2%, p<0.001), hearing (32.2% vs. 6.7%, p<0.001) and movement difficulties (29.2% vs. 5.5%, p<0.001) were significantly higher in people of aged 60 years or older than those aged 30-34 years. After multivariate adjustment, the prevalence of single disability (prevalence risk ratio [PRR] 1.25, 95% CI: 1.09-1.42, p<0.001), and multiple disabilities (PRR 1.41, 95% CI 1.14-1.73, p<0.001) was higher among females than males. The prevalence of single disability and multiple disabilities was respectively 21% (PRR 1.21, 95% CI: 1.02-1.42, p<0.001) and 88% (PRR 1.88, 95% CI: 1.38-2.54, p<0.001) higher among participants with low educational attainment (primary level or less) than those with at least a secondary level of education.

CONCLUSIONS

In rural Bangladesh, the prevalence of disability is high. Public health programs should target those of low SES, older age, and female participants and aim to provide necessary supports in order to bridge disability-related inequities.

Ten Emerging Trends in the Epidemiology of Diabetic Retinopathy

PURPOSE

Diabetes is a major public health problem affecting 415 million people worldwide. With the increasing prevalence of diabetes, diabetic retinopathy (DR) is emerging as the leading cause of avoidable blindness worldwide.

METHODS

We reviewed previous and recent literature to provide an overview of emerging trends on the burden, epidemiology, risk factors, and prevention of DR.

RESULTS

First, there is clear evidence of a global increase in the prevalence of diabetes. Second, there is a decline in the incidence of blindness due to DR, particularly in developed countries. Third, diabetic macular edema (DME) rather than proliferative diabetic retinopathy (PDR) is the increasingly common cause of visual impairment. Fourth, DR awareness remains patchy and low in most populations. Fifth, hyperglycemia remains the most consistent risk factor for DR in type 1 diabetes across different studies and populations. Sixth, in contrast, blood pressure is an important risk factor for DR in type 2 diabetes. Seventh, the relationship between dyslipidemia and DR remains unclear, with inconsistent results from different studies and trials. Eighth, the utility of predictive models incorporating multiple risk factors for assessing DR risk requires evaluation. Ninth, photographic screening of DR using tele-ophthalmology platforms is increasingly recognized as being feasible and cost-effective. Finally, DR prevention in low-resource settings cannot follow models developed in high-resource countries and requires different strategies.

CONCLUSIONS

The ten trends we observed in the current review may guide planning of public healthcare strategies for the management of DR and prevention of blindness.
