Prevalence and associated factors of refractive error among adults in South Ethiopia, a community-based cross-sectional study.

INTRODUCTION: The increasing prevalence of refractive error has become a serious health issue that needs serious attention. However, there are few studies regarding the prevalence and associated factors of refractive error at the community level in Ethiopia as well as in the study area. Therefore, providing updated data is crucial to reduce the burdens of refractive error in the community. OBJECTIVE: To assess the prevalence and associated factors of refractive error among adults in Hawassa City, South Ethiopia, 2023. METHOD: A community-based cross-sectional study was conducted on 951 adults using a multistage sampling technique from May 8 to June 8, 2023, in Hawassa City, South Ethiopia. A pretested, structured questionnaire combined with an ocular examination and a refraction procedure was used to collect data. The collected data from the Kobo Toolbox was exported to a statistical package for social sciences for analysis. Binary and multivariable logistic regression analyses were performed. A P-value of less than 0.05 was considered statistically significant in the multivariable analysis. RESULT: A total of 894 study participants were involved in this study with a 94.1% response rate. The prevalence of refractive error was 12.3% (95% CI: 10.2, 14.5%). Regular use of electronic devices (adjusted odds ratio = 3.64, 95% CI: 2.25, 5.91), being diabetic (adjusted odds ratio = 4.02, 95% CI: 2.16, 7.48), positive family history of refractive error (adjusted odds ratio = 2.71, 95% CI 1.59, 4.61) and positive history of cataract surgery (adjusted odds ratio = 5.17, 95% CI 2.19, 12.4) were significantly associated with refractive error. CONCLUSION AND RECOMMENDATION: The overall magnitude of refractive error in our study area was high. Regular use of electronic devices, being diabetic, positive family history of refractive error, and a positive history of cataract surgery were associated with refractive error.

Factors Affecting Unmet Need for Presbyopia Correction Among School Teachers in Debre Tabor Town, Northwest Ethiopia.

Background: Uncorrected presbyopia is the leading cause of near visual impairment among working-age adults in the world. In Ethiopia, there was limited evidence on the magnitude of uncorrected presbyopia and its associated factors among school teachers. Therefore, this study aimed to determine the magnitude of untreated presbyopia and its associated factors among school teachers in Debre Tabor town, Northwest Ethiopia. Methods: An institution-based cross-sectional study was conducted on 448 school teachers at Debre Tabor town using a simple random sampling technique. The data were collected using a face-to-face interview and a comprehensive ocular examination. A binary multivariable logistic regression model was conducted to identify associated factors of the uncorrected presbyopia. Results: Generally, the prevalence of uncorrected presbyopia among school teachers was 63.62% (95% CI: 59.2-67.9). Age (35-45) (AOR: 4.56, 95% CI: 1.74, 11.91), female gender (AOR: 3.03, 95% CI: 1.75, 5.26), unaware of presbyopia (AOR: 2.35, 95% CI: 1.30, 4.25), unaware of refraction site (AOR: 4.21, 95% CI: 2.42, 7.33), no eye checkup history (AOR: 2.76, 95% CI: 1.52, 5.01), and no family history of spectacle use (AOR: 2.61, 95% 4.67) were significantly associated with uncorrected presbyopia. Conclusion: In the current study, the magnitude of uncorrected presbyopia was high. Age below 45 years, female gender, lack of awareness of presbyopia and refraction site, lack of history of eye checkups, and family spectacle use were significantly associated with uncorrected presbyopia. The early correction of presbyopia, health education on presbyopia, and the provision of affordable spectacle corrections for school teachers were recommended.

Symptomatic dry eye disease and associated factors among postgraduate students in Ethiopia.

BACKGROUND: Symptomatic dry eye disease is a growing public health challenge especially among those who are visual display unit (VDU) users and other long-time near activity workers. Globally, computer user adults experience a surge in the prevalence of dry eye. Data is insufficient on the prevalence of dry eye disease among postgraduate students in Ethiopia. Therefore, the present was aimed to assess the prevalence of dry eye and its associated factors among postgraduate students at the University of Gondar, Northwest Ethiopia. METHODS: A cross-sectional study was conducted on a total of 423 postgraduate students who were selected based on a simple random sampling technique. Data was collected through online symptom-based ocular surface disease index questionnaire. Binary logistic regression was used to test the association and p-value of <0.05 was considered to determine the significance of the association. RESULTS: From the total postgraduate students, 404 completed the study with a response rate of 95.5%. The prevalence of symptomatic dry eye disease was 50.5% (95% CI, 45.1%-54.9%). Average continuous visual display unit use for 2-4hours per day[AOR = 2.57 (95% CI, 1.27-5.21)] and for> 4hours per day[AOR = 3.77 (95% CI 1.87-7.59)], duration of visual display unit use for 3-5 years [AOR = 2.24 (95% CI, 1.17-4.31)], 6-8 years [AOR = 2.46 (95% CI,1.31-4.62)] and > 8 years [AOR = 3.25 (95% CI, 1.63-6.48)], average sleeping hour < 7 hours/day within last week [AOR = 2.17 (95% CI, 1.35-3.49)] and current known allergic conjunctivitis [AOR = 5.42 (95% CI, 2.43-12.10)] were significantly associated with symptomatic dry eye disease. CONCLUSION AND RECOMMENDATION: In this study, about half of postgraduate students faced symptomatic dry eye disease. Significant association was observed between symptomatic dry eye disease and average continuous hours of visual display unit use, duration of visual display unit use in years, shortage of sleep and current known allergic conjunctivitis. It is advisable for postgraduate students to limit screen exposure hour and establish regular breaking time along their exposure. It is also advisable to have optimum sleep as possible. It is also important to explore dry eye disease on a large sample incorporating clinical tests.

Attitude towards diabetes mellitus among adult communities in Gondar city, Ethiopia.

BACKGROUND: Diabetes mellitus is a metabolic disorder characterized by hyperglycemia resulting from defects in insulin secretion, insulin action, or both. Diabetes and its complications can be reduced by enhancing the attitude of the community. However, there is limited information regarding attitude towards diabetes in northwest Ethiopia. Therefore, this study determined the attitude and associated factors of diabetes mellitus among adult non-diabetic participants in Gondar city. METHODS: A community-based cross-sectional study was conducted in Gondar city. Systematic random sampling was employed to select 626 non-diabetic participants. The data were collected using a pre-tested structured questionnaire. Descriptive statistics, processing, and analysis were done using STATA version 14. Both bivariable and multivariable binary logistic regressions were used to identify the associated factors. An adjusted odds ratio with a 95% confidence interval was used to calculate a level of significance. RESULTS: Of 626 participants, 572 (91.37%) study subjects heard about diabetes mellitus. Three hundred and fifteen participants (55.07%) (95% CI: 50.9% - 59.1%) had a favorable attitude towards diabetes mellitus. Having good knowledge about diabetes (adjusted odds ratio = 2.69, 95% CI: 1.88, 3.87), and higher educational status (adjusted odds ratio = 1.69, 95% CI: 1.04, 2.78) were positively associated with a favorable attitude towards diabetes mellitus. Female gender (adjusted odds ratio = 0.68, 95% CI: 0.47, 0.98), on the other hand, had poor attitude towards diabetes mellitus. CONCLUSION: In this study, a favorable attitude towards diabetes was low among adult non-diabetic participants. Good knowledge, higher educational status, and being male were the factors associated with a favorable attitude towards diabetes.

Factors Affecting Voluntary HIV/AIDS Counseling and Testing Service Utilization Among Youth in Gondar City, Northwest Ethiopia.

BACKGROUND: Voluntary counseling and testing (VCT) is a vital response to human immunodeficiency virus (HIV) infection among adolescents in sub-Saharan Africa. Determining the status of VCT services is important to link HIV care and antiretroviral therapy. METHODS: An institutional cross-sectional study design was conducted among 841 young students at Gondar College of Teachers' Education. A self-administered questionnaire was used to gather the data. Descriptive statistics were performed. Bivariate and multivariable binary logistic regressions were used to identify factors associated with the use of VCTs. The adjusted odds ratio (AOR) with 95% confidence was used to report statistical significance. RESULTS: The majority (71%) were aware of VCT services. More than one-third (37.8%, 95% CI: 34.6-41.2) participants had used VCT services. Having peer groups used VCT (AOR=2.04, 95% CI: 1.31-3.20), having partner (AOR: =1.6, 95% CI: 1.04-2.45), desiring to have VCT in the future (AOR=3.58, 95% CI: 1.98-6.50), being aware of VCT (AOR= 1.98, 95% CI: 1.20-3.34), knew infected/dead individuals with HIV/AIDS (AOR=1.67, 95% CI: 1.07-2.61), know test sites (AOR=2.01, 95% CI: 1.29-3.13) were positively associated, whereas being married (AOR=0.36, 95% CI: 0.20-0.63) and fear of confidentiality (AOR=0.23, 95% CI: 0.10-0.52) were major barriers to use. CONCLUSION: Low use of VCTs, which was far away from the 90:90:90 WHO goal, has been noted. The use of VCT services was associated with having peer groups that used VCT, having a partner, wanting to have VCT in the future, knowing the infected/dead individual with HIV/AIDS, fear of confidentiality of results, knowing the test sites, and having awareness of VCT. Efforts are needed to strengthen the health system that also needs to pay attention to education about HIV and VCT.
