Background/Objectives: Personal listening devices (PLDs) have become ubiquitous in modern daily life, raising growing concerns about their cumulative impact on auditory health. This study examined the prevalence and patterns of PLD use and the independent predictors of perceived hearing handicap among Saudi adults. Methods: A nationwide cross-sectional survey was conducted between November 2025 and January 2026 among 2018 adults (aged 18 years or older) residing in Saudi Arabia. Participants completed a self-administered online questionnaire assessing sociodemographic characteristics, PLD usage patterns, and hearing handicap measured by the Revised Hearing Handicap Inventory (RHHI-18). Results: Participants had a mean age of 29 ± 12 years, 54.0% were female, and 93.9% were Saudi nationals. Earphones and headphones were used by 51.1% and 47.7% of participants, respectively, and 68.1% reported current use of at least one personal listening device. The mean RHHI-18 total score was 10 ± 18, and 23.0% of participants scored within the hearing handicap range (mild-to-moderate: 16.2%; significant: 6.8%). All PLD use categories were independently associated with higher RHHI-18 scores relative to non-use: headphones only (beta = 4.58; p < 0.001), earphones only (beta = 3.29; p = 0.002), and combined use (beta = 2.87; p = 0.005). Further independent correlates of higher RHHI-18 scores were stroke (beta = 21.51; p < 0.001), diabetes mellitus (beta = 8.64; p < 0.001), hypertension (beta = 4.84; p = 0.006), non-Saudi nationality (beta = 3.92; p = 0.014), male sex (beta = 3.09; p < 0.001), and older age (beta = 0.16; p = 0.002). Conclusions: PLD use is highly prevalent among Saudi adults and is independently associated with greater perceived hearing handicap. These findings support public health efforts promoting safe listening practices at the population level.

Background/Objectives: Lumbar puncture (LP) is an essential diagnostic and therapeutic procedure in neurological practice. Despite its clinical value, misconceptions and fear may influence its acceptance among the public. This study aimed to assess knowledge, attitudes, and misconceptions regarding LP among adults in Saudi Arabia and to examine associated sociodemographic factors. Methods: A cross-sectional study was conducted between June 2025 and January 2026 using a structured, self-administered online questionnaire adapted from a previously validated instrument. Adults aged ≥18 years residing in Saudi Arabia were recruited via convenience sampling through open social media channels, so the sample is self-selected rather than population-representative. Knowledge and attitude scores were categorized into defined levels, and multivariable regression analyses were performed to identify independent predictors. Results: A total of 1267 participants were included. Knowledge of LP was limited (mean 6.1 ± 3.9 of 18), with 905 (71%) scoring poor and only 362 (29%) demonstrating good knowledge; misconceptions about complications such as urinary incontinence and erectile dysfunction were common. Attitudes appeared favorable, with 1182 (93%) reaching the pre-specified 50% threshold, but this cut-off is lenient because an entirely neutral respondent scores 60% on a summed five-point scale, and only 692 (55%) agreed they would sign consent if their physician recommended LP. Knowledge and attitude were weakly but significantly related (r = 0.21, 95% CI 0.16 to 0.26; adjusted β = 0.25 per additional correct item, p < 0.001). Higher education, student status, healthcare occupation, and higher income predicted better knowledge, and male sex predicted lower knowledge (all p < 0.05), whereas sociodemographic factors were weakly associated with attitude. Conclusions: Among self-selected online respondents in Saudi Arabia, knowledge of lumbar puncture was limited while attitudes were comparatively favorable, and the two were weakly but positively related. Targeted educational interventions are warranted to address misconceptions, enhance public awareness, and support informed decision-making within the healthcare system.
