Functional disability in community-dwelling elderly: the role of cataracts and contextual factors

Cataract and associated factors among adults visiting ophthalmic clinic at Debre Markos comprehensive specialized hospital, northwest Ethiopia, 2020

Introduction:

Globally, it is estimated that 2.2 billion people have a visual impairment, of which around 65.2 million is due to cataract. Cataract is the leading cause of preventable blindness worldwide, with the greatest burden found in low-income countries. That is providing recent epidemiological data is very crucial to design intervention measures. The aim of this study was to assess the magnitude and associated factors of cataract among adults visiting ophthalmic clinic, Debre Markos comprehensive specialized hospital, Northwest Ethiopia, 2020.

Methods:

The sample size was calculated using single population formula and determined to be 174. All adult participants aged ⩾40 were the source population and those fulfilling the inclusion criteria were the study population. An institutional-based cross-sectional study design using a systematic random sampling technique was conducted from July to August, 2020. Semi-structured questionnaires and patients’ card were used to collect data. Data were entered into epi-data version 4.6 and the analysis was conducted using SPSS-25 software. Data were presented using graphs, tables and texts. Bivariable and multivariable binary logistic regression models were used to identify factors associated with cataract. Adjusted odds ratio with corresponding 95% confidence interval was computed to show the strength of association. A p-value < 0.05 was considered statistically significant.

Result:

From a total of 174 samples, 158 participated, giving a response rate of 90.8%. The prevalence of cataract was found to be 90 (57%). The variables—age 60–69 years (adjusted odds ratio = 6.667, 95% confidence interval: (1.662, 13.101)); age 70–79 years (adjusted odds ratio = 9.583, 95% confidence interval: (2.840, 32.342)), and single marital status (adjusted odds ratio = 2.945, 95% confidence interval: (1.241, 6.989))—had a significant association with cataract.

Conclusion:

The prevalence of cataract was found to be very high, which needs immediate intervention. Older age and single marital status were found to be significantly associated with cataract prevalence.

Fatores associados à incapacidade funcional de idosos com catarata: revisão integrativa

Resumo Objetivo identificar as evidências científicas disponíveis na literatura sobre os fatores associados à incapacidade funcional de idosos com catarata. Métodos revisão integrativa da literatura realizada nas bases de dados PubMed, Web of Science, LILACS e CINAHL. Incluíram-se os artigos originais que responderam à questão norteadora: quais as evidências científicas sobre os fatores associados à incapacidade funcional de idosos com catarata? Resultados foram incluídos seis artigos, a maioria foi publicada a partir do ano 2000 (n=4) e realizada na América (n=3). Predominaram os estudos do tipo longitudinal (n=3) com nível de evidência IV, e transversal (n=3) com nível de evidência VI, e que realizaram análise de caminhos (n=3). Com base nos achados, emergiram três categorias temáticas: características demográficas; relacionadas à saúde ocular, física e mental, e comportamentais. Conclusão a incapacidade funcional de idosos com catarata pode ser resultante de características demográficas, relacionadas à saúde ocular, física e mental, e comportamentais.

Factors associated with falls in older adults with cataracts

The aim of the present study was to evaluate factors associated with falls in community-dwelling older adults diagnosed with cataracts. An analytical, cross-sectional study was conducted with a sample of community-dwelling older adults residing in the Federal District of Brazil. Interviews and assessment tools were administered, such as the Timed Up and Go test, Short Physical Performance Battery (SPPB), Biodex Balance System, Katz Index, Lawton Scale, Minnesota Leisure Time Physical Activity Questionnaire and Mini Mental State Examination. Statistical analysis involved binary logistic regression. One hundred forty-two older adults (85 with cataracts) participated in the study (mean age: 69.39 ± 5.67 years). Falls were associated with the female sex (OR: 4.45) and sub-maximum score on the SPPB (OR: 3.53) among patients with cataracts, whereas multimorbidity (OR: 5.10) was the risk factor risk for older adults without cataracts. The data suggest different risk factors for falls among older adults diagnosed with cataracts.
