Knowledge of ocular complications of diabetes in community-based people with type 2 diabetes: The Fremantle Diabetes Study II

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.

Use of Eye Care Service and Associated Factors Among Adult Diabetic Patients Attending at Diabetic Clinics in Two Referral Hospitals, Northeast Ethiopia

PURPOSE

The objective of this study was to determine the proportion of use of eye care service and associated factors among adult diabetic patients attending diabetic clinics in two referral hospitals, Northeast Ethiopia, 2020.

METHODS

A hospital-based cross-sectional study was carried out with a sample size of 546 at Dessie and Debre-Birhan Comprehensive Specialized Hospitals from July 06 to August 14/2020. Systematic random sampling with a sampling fraction of 2 was employed to select study participants at outpatient departments in diabetic clinics. A pre-tested structured questionnaire, checklist, and visual acuity chart were used to collect the data. The collected data were entered into EPI-data version 4.4 and analyzed using Statistical Package for Social Sciences (SPSS) version 25. Binary logistic regression was fitted to identify the possible factors associated with the outcome variable, and the strength of association was expressed using an adjusted odds ratio at a 95% confidence interval. Variables with p-values of less than 0.05 were considered statistically significant.

RESULTS

A total of 531 adult patients with diabetes participated with a response rate of 97.3%. In this study, the proportion of use of eye care service within the past 1 year was 31.5% (95% CI: 27.5, 35.4). Age from 40 to 64 years (AOR=2.86, 95% CI; 1.43,5.70) and >65 years (AOR=3.15, 95% CI: 1.32,7.50), duration of diabetes 6-10 years (AOR=2.15, 95% CI: 1.26, 3.69) and >11 years (AOR=2.93, 95% CI: 1.51, 5.69), presence of visual symptoms (AOR=3.12, 95% CI: 1.56, 6.18), good attitude on the need of a regular eye checkup (AOR=2.87, 95% CI: 1.68, 4.94), and good knowledge about diabetic ocular complication (AOR=2.29, 95% CI: 1.33, 3.94) were positively associated with the use of eye care service.

CONCLUSION

The proportion of use of eye care service among adult diabetic patients was low. The use of eye care service was significantly and independently associated with older age, longer duration of diabetes, presence of visual symptoms, good attitude on the need of a regular eye checkup, and good knowledge about diabetic ocular complication. We recommend that the patients with diabetes should be taught about diabetic ocular complications and the importance of regular eye check-ups by health professionals to increase utilization of eye care services by patients with diabetes.
