ABSTRACT

INTRODUCTION: Childhood blindness is defined as a group of eye diseases occurring in childhood or early adolescence. Good parental knowledge of childhood blindness is important for early detection and management of the lifelong burden. PURPOSE: This study aimed to assess knowledge of childhood blindness and associated factors among parents or guardians. MATERIALS AND METHODS: A community-based cross-sectional study was conducted. Systematic random sampling was used to select the study participants. Data were collected by interview using a pre-tested semi-structured questionnaire. The collected data were analyzed by SPSS version 20. Multivariate logistic regression was used to identify the determinant factors, and p-values less than 0.05 were considered as statistically significant. RESULTS: A total of 524 participants were enrolled in the study, with a 98.49% response rate. The proportion of good knowledge of childhood blindness was 39.1% (95% CI: 34.9-43.3%). Being male (AOR=2.32, 95% CI: 1.4-3.87), higher educational status (AOR=6.47, 95% CI: 2.4-17.3), knowing where the child eye care center is (AOR=2.68, 95% CI: 1.5-4.7) and participation in eye care campaigns (AOR=1.95, 95% CI: 1.26-3.0) had statistically significant associations with knowledge of childhood blindness. CONCLUSION: Less than half of the study participants had good knowledge about childhood blindness. Being male, having higher educational status, knowing about the child eye care center and participation in eye care campaigns were positively associated with knowledge of childhood blindness.

ABSTRACT

BACKGROUND: An impairment of the visual system at or shortly after birth adversely affects educational performance of children which typically occurs through vision. Limited evidence on the magnitude and causes of visual impairment is one of the reasons for the low priority given to eye care in low-income countries. OBJECTIVES: To estimate the prevalence and determine the causes of visual impairment in primary school children in Gondar town, Northwest Ethiopia. MATERIALS AND METHODS: A descriptive cross-sectional study was conducted among 1289 children aged 5-15 years who were randomly selected in 9 primary schools (government and private) from May to June 2016. Visual acuity was measured at 6 m using Snellen's chart, and children with an acuity of less than 6/18 in the better eye underwent refraction and a detailed eye examination. A cause of their impairment was determined. Data were recorded using pretested tools. . Statistical Package for Social Sciences version 16 was used to enter and analyze the data using 95% confidence intervals. RESULTS: The prevalence of visual impairment was 1.8%. Refractive errors (nearly 70%) followed by strabismus and cataract, each contributing 4.3%, were the most frequent causes of visual impairment in the study population. Majority (87%) of the children had moderate degree of vision impairment, and 10-15-year age groups are the more affected ones. Children of age fifteen and above showed statistically significant association with visual impairment (p=0.005). CONCLUSION: The magnitude of visual impairment in primary school children in the study area is significant. School screening programme is recommended to minimize the burden of visual impairment in the study area.

ABSTRACT

INTRODUCTION: Low vision is a worldwide health problem in both developing and developed countries. A national survey of low vision and blindness in Ethiopia showed that the prevalence of low vision was 3.7% and that of blindness was 1.6%, whereas there is no evidence in the study area. PURPOSE: The study was aimed to assess the proportion and associated factors of low vision at the University of Gondar tertiary eye care and training center. METHODS: A hospital-based cross-sectional study was conducted on 727 study participants with a systematic random sampling technique from April 18 to May 16, 2019. Data were collected through the use of a structural questionnaire and physical eye examination. Data were entered into Epi Info version 7, and analysis was performed by using statistical package for social science (SPSS) version 20. The binary logistic regression model was fitted to identify factors associated with low vision, and variables with a P value of <0.05 in a multivariable binary logistic regression were considered as statistically significant. RESULTS: A total of 715 study participants have participated in this study with a mean age of 49.39 ± 19.93 years. The prevalence of low vision was 35.7% (95% CI: 32.3, 39.3). Being female (AOR = 1.58; 95% CI: 1.10, 2.28), no formal educational level (AOR = 2.24; 95% CI: 1.25, 4.02), history of cataract surgery (AOR = 2.58; 95% CI: 1.53, 4.36), and age ≥ 70 years (AOR: 3.96; 95% CI: 2.21, 7.10) were significantly associated with low vision. Conclusion and Recommendation. The prevalence of low vision found in this study was high as compared with the national and global magnitude. Older age, being female, previous history of cataract surgery, and no formal education were independently and significantly associated with low vision. Cataract and uncorrected refractive errors were identified as the main causes of low vision. Therefore, it requires a plan to provide an eye care education to the community, increasing the quality of cataract surgery and refractive service for the community in the catchment area.

ABSTRACT

BACKGROUND: Trachoma is an infectious eye disease caused by Chlamydia trachomatis, which is the leading infectious cause of blindness worldwide. In areas where trachoma is endemic, active trachoma is common among preschool-aged children, with varying magnitude. This study aimed to estimate the prevalence of active trachoma and associated risk factors among preschool-aged children in Dembia District, northwest Ethiopia. METHODS: A community-based cross-sectional survey was conducted among preschool-aged children of northwest Ethiopia. Multistage systematic random sampling was used to select 695 subjects. Trained clinical optometrists subjected each child to an ocular examination and assessed the presence of active trachoma. Face to face interview using pretested and structured questionnaire were conducted to collect data on possible risk factors. Trachoma cases were graded following a World Health Organization simplified grading scheme. All statistical analysis was carried out using the SPSS software version 20. Adjusted odds ratios (aORs) with 95% confidence intervals (CIs) were used to identify factors associated with active trachoma. RESULTS: Of the 681 preschool-aged children studied, 18% (95% CI: 15.4% - 21.1%) had a prevalence of active trachoma. Children who had clean faces (absence of nasal and ocular discharges) had a lower chance of having active trachoma [aOR = 0.55, 95% CI: 0.37 - 0.82]. The odds of having active trachoma decreased with an increase in the distance to a water point [aOR = 0.51, 95% CI: 0.33 - 0.78]. Similarly, no or poor utilization of liquid waste disposal in the child's household was associated with an increased chance of having active trachoma [aOR = 3.83, 95% CI: 1.26 - 11.61]. CONCLUSION: The prevalence of active trachoma in these preschool-aged children was found to be high and needs special interventions that focus on educating families about proper face washing, liquid waste disposal, and improving safe water supply near the households.

ABSTRACT

BACKGROUND: Vitamin A deficiency is the leading cause of preventable visual impairments in children. It is also an underlying cause for nearly one-fourth of global child mortality associated with measles, diarrhea, and malaria. The limited literature available in Ethiopia shows severe public health significance of vitamin-A deficiency. Hence the aim of the current study was to assess the prevalence and factors determining vitamin-A deficiency among preschool children in Dembia District, northwest Ethiopia. METHODS: A community-based cross-sectional study was conducted among preschool children of Dembia District from January to February, 2015. A multi-stage sampling, followed by a systematic sampling technique was employed to select study participants. A structured interviewer-administered questionnaire was used to collect data. Using a binary logistic regression model, multivariable analysis was fitted to identify the associated factors of vitamin-A deficiency. The adjusted odds ratio (AOR) with a 95 % confidence interval was computed to assess the strength of the association, and variables with a p value of <0.05 in multivariable analysis were considered as statistically significant. RESULTS: Six hundred eighty-one preschool children were included in the study, giving a response rate of 96.5 %. The overall prevalence of xerophthalmia was 8.6 %. The result of the multivariable analysis revealed that nonattendance at the antenatal care clinic [AOR 2.65,95 % CI (1.39,5.07)], being male [AOR 1.81, 95 % CI (1.01,3.24)], and in the age group of 49-59 months [AOR 3.00, 95 % CI (1.49,6.02)] were significantly associated with vitamin-A deficiency. CONCLUSIONS: Vitamin-A deficiency is a severe public health problem in the study area. Further strengthening antenatal care utilization and giving emphasis to preschool children will help to mitigate vitamin-A deficiency in the study area.

ABSTRACT

BACKGROUND: Stunting has been the most pressing public health problem throughout the developing countries. It is the major causes of child mortality and global disease burden, where 80 % of this burden is found in developing countries. In the future, stunting alone would result in 22 % of loss in adult income. About 40 % of children under five-years were stunted in Ethiopia. In the country, about 28 % of child mortality is related to undernutrition. Thus, the aim of this study was to determine the prevalence and determinants of stunting among preschool children in Dembia district, Northwest Ethiopia. METHODS: A community based cross-sectional study was carried out in Dembia district, Northwest Ethiopia from January 01 to February 29, 2015. A multi-stage sampling followed by a systematic sampling technique was employed to reach 681 mother-child pairs. A pretested and structured questionnaire was used to collect data. After exporting anthropometric data to ENA/SMART software version 2012, nutritional status (stunting) of a child was determined using the WHO Multicenter Growth Reference Standard. In binary logistic regression, a multivariable analysis was carried out to identify determinants of stunting. The Adjusted Odds Ratio (AOR) with a 95 % confidence interval was computed to assess the strength of the association, and variables with a P-value of <0.05 in multivariable analysis were considered as statistically significant. RESULTS: A total 681 of mother-child pairs were included in the study. The overall prevalence of stunting was 46 % [95 % CI: 38.7, 53.3 %]. In multivariable analysis, the odds of stunting was higher among children whose families had no latrine [AOR = 1.6, 95 % CI: 1.1, 2.2)]. Likewise, children living in household with more than four family size [AOR =1.4, 95 % CI: 1.1, 1.9)] were more likely to be stunted. CONCLUSIONS: This study confirms that stunting is a very high public health problem in Dembia district. The family size and latrine availability were significantly associated with stunting. Hence, emphasis should be given to improve the latrine coverage and utilization of family planning in the district.
