“…However, this study was weak in representativeness due to the relatively small sample size of fewer than 1,000 individuals (632 older adults aged 70 years and older). Our study specially investigated the associations between sleep duration and dual sensory impairment (both visual and hearing), indicated that individuals with short sleep duration had a higher risk of visual, hearing, and dual sensory impairments, consistent with the results of previous studies (Ramos et al, 2014;Ghemrawi et al, 2021). Nevertheless, our results did not find out any significant association between long sleep duration and sensory impairment.…”

“…Previous studies also investigated the associations between sleep duration and sensory functions, however, most of them only focused on one type of sensory impairment (Ramos et al, 2014;Ghemrawi et al, 2021). Peltzer and Phaswana-Mafuya (2017) analyzed data from the Study of Global Aging and Adults Health (SAGE) wave 1 in 2008 and noted that individuals with short sleep duration (≤ 5 h per day) had a higher risk of self-reported visual impairment.…”

ObjectiveStudies of sleep duration in relation to the risk of sensory impairments other than dementia are scarce. Little is known about the associations between sleep duration and sensory impairments in China. This study aims to explore the associations between sleep duration and single or dual sensory impairments (visual and/or hearing).MethodsThis cross-sectional study used the data from 17,668 respondents were drawn from the 2018 survey of the China Health and Retirement Longitudinal Study (CHARLS), an ongoing national longitudinal study of Chinese adults aged 45 years and above. The duration of sleep per night was obtained from face-to-face interviews. The presence of sensory impairments was measured by self-reported visual and hearing functions. Multivariable generalized linear models (GLM) with binomial family and log link to assess the associations between sleep duration and sensory impairments.ResultsOf the 17,668 respondents, 8,396 (47.5%) were men. The mean (SD) age was 62.5 (10.0) years old. Respondents with short (≤ 4, 5 h per night) sleep duration had a significantly higher risk of visual, hearing and dual sensory impairments than those who slept for 7 h per night after adjusting for covariates (P < 0.05). Meanwhile, respondents who slept for 6 h per night had a higher risk of hearing impairment (P = 0.005). Further analysis suggested a U-shaped association between sleep duration and sensory impairments. When sleep duration fell below 8 h, increased sleep duration was associated with a significantly lower risk of visual (OR, 0.93; 95%CI, 0.88–0.98; P = 0.006), hearing (OR, 0.89; 95% CI, 0.86–0.93; P < 0.001), and dual (OR, 0.90; 95% CI, 0.87–0.94; P < 0.001) impairments. When sleep duration exceeded 8 h, the risk of visual (OR, 1.09; 95% CI, 1.00–1.19; P = 0.048), hearing (OR, 1.04; 95% CI, 0.97–1.11; P = 0.269), and dual (OR, 1.07; 95% CI, 1.00–1.14; P = 0.044) impairments would increase facing prolonged sleep duration. Women and the elderly aged over 60 years old were more sensitive to short sleep duration and experienced a higher risk of sensory impairments.ConclusionIn this study, short sleep duration was associated with a higher risk of visual and hearing impairments. Future studies are needed to examine the mechanisms of the associations between sleep duration and sensory impairments.

“…However, the finding of this study was higher than the prevalence reported in Ghana 5.8% [ 36 ], Nigeria (5.02%) [ 37 ], (3.5%) [ 38 ], USA (7.5%) [ 39 ], Malaysia (8.9%) [ 40 ] and china (2.7%) [ 41 ]. But lower than the finding of the study in Gondar 26.8% [ 18 ], Debre Berhan (16.8%) [ 42 ], Nigeria 19% [ 43 ], Egypt (23.9%) [ 44 ], Zimbabwe 56.8% [ 45 ], Pakistan (26.7%) [ 46 ], United Arab Emirates and Lebanon (18.3%) [ 47 ] and England (17%) [ 48 ]. The possible reasons for this difference might be due to the difference in the study population, sample size, variation in geographical area, ethnicity.…”

Background Visual impairment (VI) is a decreased ability to see things which is critical problem for health professionals and students to whom normal vision is essential for their daily activity. If it is not timely managed, visual impairment leads to physical, psychological, and socio-economic malfunctions to the victims and nation. Despite the above impacts, currently there is no study in Ethiopia on this topic. Therefore, this study aimed to determine the prevalence of visual impairment and its associated factors among Medical and Health Science students at the University of Gondar. Methods A cross-sectional study was conducted from January to March 2020 among Medical and Health Science students. After recruiting study participants using systematic random sampling technique, we applied pre-tested self-administered questionnaire for sociodemographic variables and also visual acuity measurement was performed using Snellen chart placed at a distance of 6 meters. Visual acuity tested separately for each eye and for both eyes in a well- illuminated area. Pinhole was used for those participants with a visual acuity of < 6/9. Participants with a presenting visual acuity of < 6/12 in the better eye were diagnosed as having visual impairment. Epi data version 3.1 and stata version 14 were used for data entry and statistical analysis, respectively. Binary logistic regression was used, and the Adjusted Odds Ratio (AOR) with the 95% Confidence Interval (CI) was reported to declare the statistical significance and strength of association between VI and independent variables. Results A total of 654 students were screened for visual acuity. The prevalence of visual impairment was 12.5% (95% CI: 10.21, 15.31). Age above 25 years (AOR = 1.8; 95% CI: 1.02, 3.26) and current alcohol drinking (AOR = 2.9; 95% CI: 1.7, 5.00), were statistically significant factors of visual impairment. Conclusion The prevalence of visual impairment among medical and health science students was high. Age of study participant and current alcohol consumption were statically significant factors. This study warrants the routine screening of Medical and Health science students for visual impairment.
