SUBJECTS AND METHODS: Participants were 99 normal, healthy, full-term newborn babies with chronological age between 11 and 128 hours of age (mean=46.73, standard deviation=26.36). A cross-sectional study design was used to measure WBA at 16 one-third octave frequency points from 99 neonates comprising of three ethnic groups: Malays (n=58), Chinese (n=13) and Indians (n=28). A total of 165 ears (83.3%) that passed a battery of tests involving distortion product otoacoustic emissions, 1 kHz tympanometry and acoustic stapedial reflex were further tested using WBA. Moreover, body size measurements were recorded from each participant.
RESULTS: The Malays and Indians neonates showed almost identical WBA response across the frequency range while the Chinese babies showed lower absorbance values between 1.25 kHz and 5 kHz. However, the differences observed in WBA between the three ethnic groups were not statistically significant (p=0.23). Additionally, there were no statistically significant difference in birth weight, height and head circumference among the three ethnic groups.
CONCLUSIONS: This study showed that Malays, Chinese and Indians neonates were not significantly different in their WBA responses. In conclusion, to apply for the ethnic-specific norms is not warranted when testing neonates from population constitute of these three ethnicities.
METHODS: This cross-sectional survey was conducted in Rawalpindi, Pakistan from March 1 to August 31, 2023. A total of 150 parents (79 fathers and 71 mothers) of children aged 0-12 years were recruited through convenience sampling at public locations such as schools, malls, and hospitals. Data were collected through face-to-face interviews using the validated "Parental Knowledge and Attitudes towards Childhood Hearing Loss Questionnaire," administered by a graduate student to assess parental knowledge and attitudes about childhood hearing loss. Descriptive statistics determined the percentage of correct responses and knowledge/attitudes scores. Chi-square tests explored associations between demographic factors and parental perspectives.
RESULTS: Overall, 67.3% of parents demonstrated good knowledge of childhood hearing loss. Notably, parents scored high on recognizing congenital causes (79.3%) but displayed low awareness of measles as a risk factor (29.3%). Significant gender disparities emerged in parental knowledge, with mothers exhibiting superior knowledge compared to fathers regarding newborn screening (63.4% vs. 46.8%), treatment availability (81.7% vs. 64.6%), and educational inclusion for children with hearing impairment (57.7% vs. 38.0%). Despite these knowledge gaps, parents generally held positive attitudes towards childhood hearing loss, with an average score of 94.7%. Gender and educational level significantly influence knowledge and attitudes.
CONCLUSIONS: Although parents in Rawalpindi generally have a good understanding and positive attitudes towards childhood hearing loss, gaps in knowledge about preventable causes and gender disparities need attention. Providing tailored counselling for higher-risk, less educated groups and expanding policies for paediatric audiology services nationwide can help address these issues.
OBJECTIVES: This study aimed to assess PCPs' knowledge and attitudes toward childhood hearing loss, investigate the association between knowledge and attitudes, and examine the influence of demographic factors on PCPs' knowledge and attitudes towards childhood hearing loss.
METHODS: This cross-sectional study was conducted from 30 November 2017 to 30 July 2018 at three public health clinics in Malaysia, specifically in the Federal Territory of Kuala Lumpur, Selangor, and Terengganu. A self-administered questionnaire assessed PCPs' knowledge of general facts, diagnosis and intervention, and risk factors for childhood hearing loss. Additionally, the questionnaire evaluated PCPS' attitudes across cognitive, affective, and behavioural domains regarding childhood hearing loss.
RESULTS: Most participants lacked sufficient knowledge about childhood hearing loss, with 61.4% not seeing it as a major health issue. Almost half (45.9%) didn't know that children with hearing loss can succeed in regular schools, and 78% were unaware that hearing aids don't fully restore normal hearing. Participants' awareness of risk factors varied widely, ranging from 24.6% to 90.3%. Despite these knowledge gaps, participants generally had positive attitudes towards childhood hearing loss, especially in cognitive and behavioural aspects. The study found a strong positive link between knowledge and attitudes, but demographic factors didn't significantly affect them.
CONCLUSIONS: This study highlights the urgent need to address knowledge gaps among Malaysian PCPs regarding childhood hearing loss. While these knowledge gaps exist, PCPs' positive attitudes form a foundation for developing targeted educational interventions to improve PCPs' knowledge and skills in managing childhood hearing loss. Collaborative efforts are essential to translate these findings into meaningful improvements in paediatric audiological care.
