Knowledge of cataracts and eye care utilization among adults aged 50 and above in rural Western China

Level of eye healthcare utilisation and associated factors in Gamo and Gofa Zones, Southern Ethiopia: a community-based, cross-sectional study

OBJECTIVE

About 90% of eye health problems are preventable or curable with existing cost-effective interventions. There is limited evidence on eye healthcare utilisation (ECU) and the factors influencing it in the study area. This study aimed to determine the level of ECU and the associated factors in Southern Ethiopia.

DESIGN

A community-based, cross-sectional study was conducted in Southern Ethiopia from 1 June to 15 July 2023. Data were analysed using SPSS V.27.

SETTING

Two selected districts (Dita and Uba Debretsehay) in Southern Ethiopia.

PARTICIPANTS

Permanent residents living in randomly selected kebeles.

OUTCOME MEASURE

The level of ECU was the outcome measure. A binary logistic regression model was used to check the association between explanatory variables and the dependent variable. To avoid many variables and unstable estimates and to control for possible confounders in the subsequent model, only variables that reached a p value of less than 0.25 on binary analysis were used in the multivariate logistic regression analysis to identify factors independently associated with ECU.

RESULTS

992 respondents participated in this study, with a response rate of 95.4%. The prevalence of ECU within the past 2 years was 21.6% (95% CI 19.0, 24.3). The reported barriers to ECU were lack of awareness (123, 40.6%) and lack of money (58, 19.2%). Age <30 years (adjusted OR (AOR)=2.7; 95% CI 1.5, 4.6), being male (AOR=2.2; 95% CI 1.4, 3.6), shorter travel time (AOR=2.0; 95% CI 1.3, 3.1), undergoing regular vision check-ups (AOR=5.4; 95% CI 3.47, 8.37), history of eye diseases (AOR=4.8; 95% CI 2.5, 9.1) and having trichiasis (AOR=1.5; 95% CI 1.1, 2.3) were positively associated with eye care service utilisation. Low wealth quantile (AOR=0.62; 95% CI 0.39, 0.98) and poor knowledge (AOR=0.26; 95% CI 0.16, 0.44) were negatively associated with eye care service utilisation.

CONCLUSIONS

The ECU within the past 2 years was a quarter. Socioeconomic factors, disease-related factors and respondent knowledge are independently associated with ECU. Designing strategies that can improve the capacity of healthcare facilities and patient awareness is important in order to reduce barriers and improve service utilisation. Researchers interested in working in the area should focus on community-specific approaches that can improve community health literacy by using stronger study designs.

Perceptions and Misconceptions About Eye Disease Treatment: A Cross-Sectional Study From Jazan, Saudi Arabia

BACKGROUND

Eye diseases such as cataracts and glaucoma significantly contribute to vision impairment and blindness worldwide. While cataracts are the leading cause of preventable blindness, glaucoma, often referred to as the "silent thief of sight", can lead to irreversible vision loss if untreated. Despite their prevalence, awareness and understanding of these conditions remain low, particularly in regions like Saudi Arabia, where demographic changes and rising diabetes rates exacerbate the burden of eye diseases. This study aims to assess the knowledge and perceptions of cataracts and glaucoma among residents of Jazan to identify gaps and inform public health interventions.

METHODS

A cross-sectional online survey was conducted among participants aged 18 years and older in Jazan. The structured questionnaire assessed demographic information, awareness of cataracts and glaucoma, understanding of symptoms, and perceptions of treatment options. Data collection took place over four weeks, with statistical analysis performed using descriptive statistics to summarize findings.

RESULTS

A total of 426 participants completed the survey. Of these, 43.9% (n = 186) were aware of cataracts, while only 28.1% (n = 119) recognized glaucoma. Awareness of cataract symptoms varied, with 43.4% (n = 184) identifying blurred vision; however, 71.5% (n = 303) reported being unaware of glaucoma. A significant majority (68.2%, n = 289) recognized surgical treatment for cataracts, but only 27.8% (n = 118) were aware of treatment options for glaucoma. High levels of uncertainty about both conditions suggest a critical lack of understanding in the community.

CONCLUSION

This study emphasizes the need for improved awareness and understanding of cataracts and glaucoma in Jazan, Saudi Arabia. By implementing targeted public health strategies, healthcare providers can enhance knowledge, encourage regular eye examinations, and ultimately reduce the burden of visual impairment in the community.

To investigate the individual and household-level factors influencing the willingness to pay for cataract surgery among patients aged 50 years and older in rural China: a cross-sectional study

OBJECTIVES

To investigate the factors influencing the willingness to pay (WTP) for cataract surgery among patients aged 50 years and older in rural China at both individual and household levels.

DESIGN

A cross-sectional study.

SETTING

The study was conducted in Gansu, China.

PARTICIPANTS

Patients aged ≥50 years who were diagnosed with cataracts indicated for surgery and lived rural in Gansu from October to December 2020 were included in the study.

PRIMARY AND SECONDARY OUTCOME MEASURES

The main study outcome was the patients' WTP for cataract surgery. The association of individual characteristics, knowledge about cataracts, health status and household characteristics with patients' WTP was also evaluated based on the collected data using structured questionnaires.

RESULTS

A total of 324 (85.94%) patients in the study reported that they were willing to pay for their cataract surgery. However, only 179 (47.48%) patients were willing to pay over ¥1000 to cover the cost of cataract surgery under the New Rural Cooperative Medical System (NRCMS). Patients aged 75 years and older were significantly less likely to pay for cataract surgery (p=0.037). Better visual status (p=0.032), self-reported severe poor visual status (p=0.001), higher annual household income (p=0.052) and a higher level of children's education (p=0.076) were significantly more likely to pay for cataract surgery.

CONCLUSIONS

The WTP for cataract surgery in rural China is still insufficient. More than half of patients' WTP for surgery do not cover the cost of cataract surgery after reimbursement by the NRCMS. Both individual and household characteristics contribute to the low WTP for cataract surgery.

Factors influencing cataract awareness and treatment attitudes among the middle-aged and older in western China's rural areas

Purpose

This study was conducted to determine the level of knowledge about cataracts and the associated factors among adults aged 50 and above in rural areas of Qingcheng county in Gansu Province of Western China, 2020.

Methods

A large community-based cross-sectional study was conducted among the randomly selected 1,503 adults aged 50 and above from October to December 2020. Data were collected by conducting eye examinations and face-to-face interviews. Multivariate binary logistic regression and multivariate linear regression were used to identify associated factors of knowledge about cataracts. Odds Ratio (OR), Coefficient (C), and 95% Confidence Interval (CI) were reported to declare the statistical associations between knowledge about cataracts and the independent variables.

Results

Of the 1,503 study participants, 1,078 (71.7%) had good knowledge about cataracts. The primary school completed [OR = 1.43 (95% CI 1.08-1.90), P = 0.012], Secondary school & above [OR = 2.69 (95% CI 1.86-3.89), P <0.001], Examine for cataract [OR = 1.82 (95%CI 1.27-2.62), P = 0.001] were positively significantly associated with knowledge about cataracts. Whereas eye examinations [OR = 0.73(95% CI 0.55-0.96), P = 0.022] were negatively associated with knowledge about cataracts. Multivariate linear regression analyses showed a significant negative correlation between age and knowledge of cataract treatment options. Living with at least one child was positively correlated with knowledge of the therapeutic effects of cataracts. And monthly household income was significantly positively correlated with knowledge of the therapeutic effects of cataracts, treatment options, and the surgical reimbursement ratio for cataracts.

Conclusions

More than one-third of the participants still had poor knowledge about cataracts. The respondents with at least primary education and above, with previous examinations, and with examination for cataracts had significant associations with good knowledge about cataracts. So, it is recommended that stakeholders in different hierarchies organize health education by considering the education level of the community, focusing on cataract treatment knowledge and the surgical reimbursement ratio to improve cataract surgery rates.
