Development of an assessment instrument to measure disability related distress in primary school learners with vision impairment due to uncorrected refractive error in rural areas of KwaZulu-Natal Province, South Africa.

Doctoral Degree. University of KwaZulu-Natal, Durban.With the increasing global emphasis on improving eye health in children, numerous efforts are being implemented to meet the eye care needs of the children. There is no instrument which can be used to measure the impact of the Disability Related Distress (DRD) on children with vision impairment (VI) due to uncorrected refractive error (URE). Aim The aim of the study was to develop an assessment instrument to measure DRD in Grade 1 to Grade 5 learners with VI due to URE in a rural and semi-rural setting. Methods This mixed-method study was conducted in 4 primary schools in Pinetown, KwaZulu Natal, Durban in 3 phases. Phase 1 involved twelve focus group discussions using semi-structured interviews to identify themes that formed the DRD items in the Instrument. A topic was qualified as an item if at least two participants made substantive comments on the topic in a single focus group and the topic was discussed by at least one child in two different groups. In Phase 2, we consulted ten experts to construct an instrument for pre-testing by considering relevance, relative importance, upsetting issues and wording of the items. Issues that had a mean score < 2 for relevance or importance were excluded. In Phase 3, we pre-tested the instrument to identify missing or redundant issues. An item was included in the final instrument if the mean score of relevance was > 1.5; prevalence ratio >30% or prevalence of scores 3 or 4 >50%; range of rate of occurrence was > 2 points; no significant concerns expressed by Primary Subjects, Secondary Subjects and Tertiary Subjects, and compliance of less than 5% of the responses to the item in the debriefing session suggested that the issues were not related to VI due to URE. Results In Phase 1, thirteen children with normal vision and 63 children with VI due to URE consented to participate in the focus group discussions. Eleven themes were generated from the focus group discussions and included as items in the draft provisional list. In Phase 2, one item was excluded and the experts pointed out the need to give explanations to the children. The items included were from the domains of Loss of Self Confidence (n=3), Loss of self-worth (n=3), Loss of interconnection/ interaction with community (n=2), Suspicion, humiliation and fight (n=1) and Discrimination (n=2). In Phase 3, pre-testing was conducted on 120 children (Normal vision, NV: Mild vision impairment, MVI: Severe vision impairment, SVI: 60:30:30). The rate of occurrence of the items showed an increasing trend, from NV to MVI and SVI. The average time needed for completing the questionnaire showed an increasing trend, from NV to MVI and SVI. All eleven items in the provisional list fulfilled the retention parameters. Conclusion The developed instrument is valid, appropriate and culturally sensitive to the rural population. Its administration is resource-friendly and efficient with straightforward analysis and interpretation of data. This makes it easy to communicate the finding to a wide range of stakeholders and decision makers

Depression, anxiety, stress symptoms and their determinants among secondary students with vision impairment in rural Northwestern China during the COVID-19 pandemic

ObjectiveThe measures implemented to control the spread of Coronavirus disease 2019 (COVID-19) could affect children’s mental and vision health. Youth particularly from minority and socioeconomically disadvantaged backgrounds were more likely to be impacted by these measures. This study aimed to examine the mental health of children with vision impairment and associated factors in North-western China during the COVID-19 pandemic.MethodsA cross-sectional study was conducted among 2,036 secondary school children living in Ningxia Hui Autonomous Region. Participants completed a survey on sociodemographic and lifestyle information and answered the Chinese version of the 21-item Depression Anxiety Stress Scales (DASS-21) questionnaire. Presenting visual acuity was measured by a trained enumerator. Multivariate logistic regression analysis was used to identify potential risk factors for mental health problems.ResultsResponses from 1,992 (97.8%) children were included in the analysis after excluding those with incomplete mental health outcome data. The prevalence of depression, anxiety and stress symptoms within the dataset were 28.9, 46.4, and 22.3%, respectively. The distribution of children with different stress levels differed significantly between those with and without vision impairment (p = 0.03). Multivariable logistic regression analyses revealed that depression symptoms decreased with higher parental education (OR, 0.76, 95% confidence intervals (CI):0.63–0.96), longer sleep duration (OR, 0.90, 95% CI: 0.81–0.97) and longer study time (OR, 0.82, 95% CI: 0.74–0.91), whereas they increased with higher recreational screen time (OR, 1.19, 95% CI: 1.08–1.32). Anxiety symptoms decreased with higher parental education (OR, 0.80, 95% CI: 0.66–0.96) and increased with higher recreational screen time (OR, 1.15, 95% CI: 1.04–1.27) and being a left-behind child (OR, 1.26, 95% CI: 1.04–1.54). In addition, stress symptoms decreased with longer sleep duration (OR, 0.92, 95%CI: 0.85–0.99) and increased with higher number of siblings (OR, 1.10, 95% CI: 1.01–1.19), higher recreational screen time (OR, 1.15, 95% CI: 1.04–1.28) and older age (OR,1.12, 95% CI: 1.004–1.24).ConclusionA considerable proportion of our sample experienced mental health problems during the pandemic. Healthcare planners in China should consider interventions such as reducing recreational screen time, ensuring sufficient sleep, and timely detection of mental health symptoms among socioeconomically disadvantaged groups

School eye health- going beyond refractive error.

Health, including visual health, is inextricably linked to school achievement, quality of life, and economic productivity. Introducing health education in schools is essential as knowledge and good habits acquired at an early age are likely to persist

Disability-related-distress in primary school learners with vision impairment due to uncorrected refractive error in KwaZulu-Natal Province, South Africa – a qualitative study

BACKGROUND:Uncorrected refractive error (URE) is a major cause of vision impairment among children that impacts negatively on their lives including distresses. We aim to understand the disability-related distress among vision-impaired children due to URE in rural and semi-rural South Africa using qualitative techniques. METHODS:Structured focus groups of children (aged 5-12 years old) with normal vision and vision impairment due to URE from four schools in Pinetown, KwaZulu Natal, South Africa, were performed (four mixed-gender group discussions and eight single gender group discussions). We recruited the study participants after the children underwent standardised vision screening. Criterion sampling was used when selecting study participants. The interviews were transcribed to identify meaning units and broken down to condensed meaning units, which were then grouped into megathemes. Themes were then generated. RESULTS:Thirteen children with normal vision and 63 children with vision impairment due to URE participated in the twelve focus group discussions with 36 boys (47%) and 40 girls (53%). Twelve themes were generated. The megathemes were Loss of Self Confidence (number of themes (n) = 3), Loss of self-worth (n = 3), Loss of interconnection/ interaction with community (n = 2), Humiliation (n = 2) and Discrimination (n = 2). CONCLUSIONS:We found that vision impairment due to URE can cause distress in different domains in children's life and further grouped them into different themes. The themes will be used for the development of a tool to assess disability-related distress among children with vision impairment due to URE. We also recommend that distresses caused by URE should be taken into consideration when designing eye care programmes for children

Near vision correction and quality of life among textile workers.

Background: Uncorrected near vision impairment affects the performance of near vision tasks and activities for an estimated 410 million people worldwide. Once normal vision becomes blurred or impaired, the ordinary and simple daily routines of individuals become difficult; often resulting in frustration and irritation, which is consequently reflected in their quality of life. Aim: We investigated the change of vision-related quality of life (VRQoL) following near correction among textile factory workers in South Africa. Methods: Presbyopic subjects who were 40 years and older with no other eye conditions were provided near spectacle correction. We interviewed subjects to ascertain their VRQoL scores using the National Eye Institute Visual Function Questionnaire, pre-treatment and 6 months after the provision of near corrections. Setting: The study was conducted among the textile factory workers in KwaZulu-Natal, South Africa. Results: A total of 423 textile factory workers were followed up from seven textile factories in Durban. The overall increase in VRQoL scores of 21.9 (95% CI 16.7–27) was significant (p < 0.01). This translates to a 36.5% (95% CI 30.6–42.4) change in VRQoL. The increase was highest among participants of African origin 25.1 (95% CI 21.14–29.1), males 18.8 (95% CI 12.6–27.2), among those who had completed primary school 35.8 (95% CI 21.7–49.9) and among participants with other responsibilities (ironing and quality assurance) 21.9 (95% CI 16.7–27). Conclusion: Correcting near vision impairment improved the VRQoL scores of textile factory workers. The results showed that VRQoL scores increased significantly across levels of education and categories of responsibilit
