“…Our estimate of unmet need for near vision glasses (44.9%) was similar when compared to this same Tanzanian study's population aged 35+ years which found an uncorrected presbyopia prevalence of 46.5% [22] and slightly lower than studies in similar age groups in Ghana (64%) [23] and Nepal (66.1%) [24]. For hearing, the need for hearing aids (25.5%) in this study is lower than estimates from RAHL surveys, which used the same ear/hearing assessment methods, in Malawi (30.8%) [25] and China (54%) [26], likely because the focus was people 35+ compared to 50+ in the other surveys. The low coverage (<1%) is similar across all three studies [25,26].…”

Few estimates are available of the need for assistive devices (ADs) in African settings. This study aimed to estimate population-level need for glasses and hearing aids in The Gambia based on (1) clinical impairment assessment, and (2) self-reported AD awareness, and explore the relationship between the two methods. The Gambia 2019 National Eye Health Survey is a nationally representative population-based sample of 9188 adults aged 35+ years. Participants underwent standardised clinical vision assessments including the need for glasses (distance and near). Approximately 25% of the sample underwent clinical assessment of hearing and hearing aid need. Data were also collected on self-reported awareness, need and access barriers to vision and hearing ADs. Overall, 5.6% of the study population needed distance glasses (95% CI 5.0–6.3), 45.9% (95% CI 44.2–47.5) needed near glasses and 25.5% (95% CI 22.2–29.2) needed hearing aids. Coverage for each AD was very low (<4%). The agreement between self-report and clinical impairment assessment for AD need was poor. In conclusion, there is high prevalence and very low coverage for distance glasses, near glasses and hearing aids in The Gambia. Self-report measures alone will not provide an accurate estimate of AD need.

“…The observed incidence of HL in our study was lower than total prevalence reported by another study in China (1). However, results of this study were closer to prevalence of disabling HL ranged from 8.0 to 16.1% in several surveys (64)(65)(66)(67). Therefore, we applied the definition in the present study to minimize potential measurement error and focus on poor HL.…”

BackgroundHearing loss has occurred as a critical concern for aging and health. However, it remains unknown whether nocturnal sleep and midday napping duration are associated with hearing loss in middle-aged and older adults.MethodsThe study comprised 9,573 adults from China Health and Retirement Longitudinal Study, who have completed the survey for sleep characteristics and subjective functional hearing. We collected self-reported nocturnal sleep duration (<5, 5 to <6, 6 to <7, 7 to <9, ≥9 h/night) and midday napping duration (≤5, 5 to ≤30, and >30 min). The sleep information was classified into different sleep patterns. The primary outcome was self-reported hearing loss events. Multivariate Cox regression models and restricted cubic splines were used to investigate the longitudinal association of sleep characteristics with hearing loss. We applied Cox generalized additive models and bivariate exposure-response surface diagrams to visualize the effects of different sleep patterns on hearing loss.ResultsWe confirmed 1,073 cases of hearing loss (55.1% female) during the follow-up. After adjusting for demographic characteristics, lifestyle factors and health condition, nocturnal sleep with < 5 h was positively associated with hearing loss [hazard ratio (HR): 1.45, 95% confidence interval [CI]: 1.20, 1.75]. Individuals with napping for 5 to ≤30 min had a 20% (HR: 0.80, 95%CI: 0.63, 1.00) lower risk of hearing loss compared with those with napping ≤ 5 min. Restrictive cubic splines showed the reverse J-shaped association between nocturnal sleep and hearing loss. Moreover, we found significant joint effects of sleeping < 7 h/night and midday napping ≤ 5 min (HR: 1.27, 95% CI: 1.06, 1.52) on hearing loss. Bivariate exposure-response surface diagrams also reflected the finding that short sleep without napping existed the highest risk of hearing loss. Compared with persistently sleeping moderately (7–9 h/night), those who persistently slept < 7 h/night or shifted from < 7 h/night to moderate or > 9 h/night had higher risks of hearing loss.ConclusionInadequate nocturnal sleep was associated with an elevated risk of poor subjective hearing in middle-aged and older adults, while moderate napping decreased the risk of hearing loss. Keeping sleep stable within recommendation duration may be a useful strategy for preventing poor hearing loss.

“…When adjusting the grades of hearing impairment according to WHO recommendations, the prevalence of moderate to severe hearing loss among the Bangkok population was 2.8%, consistent with the nding of Ferrite's study (2017) (13) where the prevalence of moderate or greater hearing loss in northwest Cameroon was 3.6%. However, the prevalence was lower compared to studies in the Philippines and in China with the prevalence of 15 and 16.3%, respectively (9,14). The differences in the prevalence of hearing loss/hearing impairment were probably due to factors such as population sizes, sampling strategies, de nitions or criteria for grading hearing loss, and the prevalence of the outer and middle ear diseases in the population.…”

This cross-sectional random survey among Thai adults living in Bangkok aimed to identify the prevalence of hearing problems and study their relationship with personal factors. The questionnaire was interviewed. The air conduction pure-tone threshold audiometry was performed. A total of 2,463 participants (1,728 females) aged 15–96 years were included. The prevalence of hearing loss (HL) was 53.02% and increased with age. The prevalence of moderate or greater degree hearing impairment (HI) was 2.8%. The people aged 65 years and over had HL and HI more than younger people at 8.56 and 6.79 times, respectively. Males were two times more likely to have HL and HI than females. People with higher education had less chance of HL and HI than those without education or elementary level. People who ever worked in loud noises for >8 hrs. /day had HL 1.56 times more than those who never. An inconsistent correlation was found between HL, HI, and three NCDs. Although the majority of the volunteers had mild HL, it is crucial that they should be appropriately taken care of and monitored in order to prevent further loss. The questionnaire-based survey found only people with hearing problems that affect daily communication.
