Hearing threshold levels and hearing loss among people in Zhejiang, China: a population-based cross-sectional study.

ABSTRACT: Hearing loss (?26?dB threshold in the better ear), as a common chronic condition in humans, is increasingly gaining attention. Relevant research in China is relatively scarce, so we conduct a population-based study to investigate the prevalence of hearing loss among age groups, genders and ears in Zhejiang province, China, from September 2016 to June 2018.

Study design

Population-based cross-sectional study PARTICIPANTS: A total of 3754 participants aged 18-98 years and living in Zhejiang province, China.

Outcome measures

Pure-tone audiometric thresholds were measured at frequencies of 0.125-8?kHz for each subject. All participants were asked to complete a structured questionnaire, in the presence of a healthcare official.

Results

The prevalence of speech-frequency and high-frequency hearing loss was 27.9% and 42.9%, respectively, in Zhejiang. There were significant differences in auditory thresholds at most frequencies among the age groups, genders (male vs female: 31.6%vs24.1% at speech frequency; 48.9% vs 36.8% at high frequency) and ears. In addition to the common factors affecting both types of hearing loss, a significant correlation was found between personal income and speech-frequency hearing loss (OR=0.69, 95% CI 0.52 to 0.92), and between hyperlipidaemia and high-frequency hearing loss (OR=1.45, 95%?CI 1.02 to 2.07).

Conclusion

The prevalence of hearing loss was high among people living in Zhejiang, particularly males, and in the left ear. Moreover, hearing thresholds increased with age. Several lifestyle and environment factors, which can be influenced by awareness and education, were significantly associated with hearing loss.

Project description:BACKGROUND:Given that hearing loss is associated with increased social isolation, reduced earning potential and neurocognitive disease, findings of uncorrected hearing loss in the homeless population have important policy implications. We sought to estimate the prevalence of hearing impairment in an adult homeless population. METHODS:We recruited adult (age ? 18 yr) homeless people across 10 homeless shelters in Toronto between April and June 2018 using a 2-stage sampling technique. Participants were interviewed by 1 interviewer using a modified survey that had been used in previous studies looking at other health needs in homeless populations. A comprehensive head and neck examination and audiometric evaluation were performed in each participant by an otolaryngologist and an audiologist. Descriptive statistics were estimated. Audiometric data were standardized directly for age and sex to facilitate direct comparisons with the general Canadian population. RESULTS:Of the 132 people invited, 100 (75.8%) agreed to participate. The median age was 46 (interquartile range [IQR] 37-58) years. The median duration of homelessness was 24 (IQR 6-72) months. Although most participants (78) had some form of extended health care benefits through social assistance, only 22/78 (28%) were aware that hearing tests and hearing aids were covered through these programs. After direct standardization for age and sex, the proportions of participants with a speech-frequency and high-frequency hearing loss were 39.5% (95% confidence interval [CI] 30.4%-49.3%) and 51.9% (95% CI 42.2%-61.4%), respectively. Nineteen participants were hearing aid candidates, only 1 of whom owned functional hearing aids. Rates of speech-frequency hearing loss (39.5%, 95% CI 30.4%-49.3% v. 19.2%, 95% CI 16.9%-21.7%) and high-frequency hearing loss (51.9%, 95% CI 42.2%-61.4% v. 35.5%, 95% CI 33.1%-37.7%) were substantially higher than in the general Canadian population. INTERPRETATION:Our results suggest that homeless adults have a high prevalence of hearing impairment, even when living within a system of universal health insurance; awareness of health care benefits through social assistance programs was poor. Results from this study may prompt initiatives surrounding homeless outreach and health screening.

Project description:Health-related quality of life (HRQOL) has become a concept commonly used in the related research. Using the World Health Organization Quality of Life Questionnaire for Brief Version (WHOQOL-BREF), this study evaluated the Quality of Life (QOL) of people living with HIV/AIDS (PLWHA) in Zhejiang province, China, and assessed the influences of demographic, laboratory and disease-related variables on QOL. This cross-sectional study was conducted among PLWHA aged ? 18 years in Taizhou municipality, Zhejiang province, China, between August 1 and October 31, 2014. A multiple linear regression model was used to analyze the influential factors. Of 403 subjects, 72.48% were male, 72.46% had received a high- school or above education, 94.79% were of Han ethnicity, and 65.51% were non farmers. The total score of QOL was 15.99±1.99. The scores of QOL in physiological, psychological, social relation, and environmental domains were 14.99 ±2.25, 14.25 ±2.12, 13.22 ±2.37, and 13.31 ±1.99 respectively. Except the total score of QOL and the score of environmental domain (p<0.05), the scores in other domains had no significant difference with the results of the national norm level. The multiple linear regression model identified the physical domain related factors to be age (? = -0.045), CD4 count (? = 0.002), and ART adherence(? = 1.231). And it also showed that psychological domain related factors included CD4 count (? = 0.002) and WHO clinical stage (? = -0.437); social domain related factors included WHO clinical stage (? = -0.704) and ART adherence (? = 1.177); while environmental domain related factors included WHO clinical stage (? = -0.538), educational status(? = 0.549) and ART adherence(? = 1.078).Those who are young, with higher level of education, higher CD4 count and good access and adherence of ART, are likely to have better QOL among PLWHA in Zhejiang province. This suggests that in addition to ART, many other factors should be taken into consideration to improve the QOL of PLWHA. The relatively lower scores the subjects received in social relation and environmental domains also suggest that social relation and environmental interventions need to be strengthened.

Project description:BackgroundIncreased plasma total homocysteine (tHcy) is an influencing factor of cognitive impairment in the general population. However, studies on the relationship between the risk of cognitive impairment and plasma tHcy levels in patients with hypertension are limited. This study aimed to explore the association between plasma tHcy levels and cognitive function assessed by MMSE scores among hypertensive patients in China.MethodsA total of 9,527 subjects from the Chinese Hypertension Registry Study participated in this study. Plasma tHcy levels were quantified by high-performance liquid chromatography using a fluorescence detector. Cognitive assessment was performed using the Mini-Mental State Examination (MMSE). Linear regression models, two piecewise linear regression models, and smoothing curve fitting were applied to determine the relationship between plasma tHcy levels and cognitive function.ResultsThis analysis included 9,527 Chinese hypertensive adults. Based on the results of linear regression models, a negative relationship was identified between plasma tHcy levels and MMSE scores [beta coefficient (β) per standard deviation (SD) increase: -0.26, 95% confidence interval (CI) -0.35, -0.16, P < 0.001]. The fully adjusted smooth curve fitting presented a nonlinear between plasma tHcy levels and MMSE scores. The threshold effect analysis showed that the inflection point of tHcy was about 27.1 μmol/L. The effect size [β (95% CI)] per SD increase in plasma tHcy concentrations on MMSE scores was -0.93 (-1.24, -0.6) on the left side and -0.07 (-0.24, 0.10) on the right side of the inflection point (P-value for log-likelihood ratio (LLR) test was <0.001). Moreover, subgroup analyses revealed that sex could influence the negative association between plasma tHcy levels and MMSE scores up to a specific threshold (P-value for interaction <0.001). Linear regression models indicated that there was an enhanced inverse association between tHcy levels and MMSE scores in female patients with tHcy concentrations less than 26.9 μmol/L compared to male patients with tHcy concentrations less than 32.0 μmol/L.ConclusionsPlasma tHcy levels had a threshold effect on MMSE scores among hypertensive patients in China. Increased plasma tHcy levels were independently inversely associated with cognitive decline among hypertensive patients with tHcy concentrations <27.1 μmol/L.

Project description:BackgroundHearing loss and tinnitus have been linked to mild cognitive impairment (MCI); however, the evidence is constrained by ethical and temporal constraints, and few prospective studies have definitively established causation. This study aims to utilize Mendelian randomization (MR) and cross-sectional studies to validate and analyze this association.MethodsThis study employs a two-step approach. Initially, the genetic data of the European population from the Genome-wide association studies (GWAS) database is utilized to establish the causal relationship between hearing loss and cognitive impairment through Mendelian randomization using the inverse variance weighted (IVW) method. This is achieved by identifying strongly correlated single nucleotide polymorphisms (SNPs), eliminating linkage disequilibrium, and excluding weak instrumental variables. In the second step, 363 elderly individuals from 10 communities in Qingdao, China are assessed and examined using methods questionnaire survey and pure tone audiology (PTA). Logistic regression and multiple linear regression were used to analyze the risk factors of MCI in the elderly and to calculate the cutoff values.ResultsMendelian randomization studies have shown that hearing loss is a risk factor for MCI in European populations, with a risk ratio of hearing loss to MCI loss of 1. 23. The findings of this cross-sectional study indicate that age, tinnitus, and hearing loss emerged as significant risk factors for MCI in univariate logistic regression analysis. Furthermore, multivariate logistic regression analysis identified hearing loss and tinnitus as potential risk factors for MCI. Consistent results were observed in multiple linear regression analysis, revealing that hearing loss and age significantly influenced the development of MCI. Additionally, a notable finding was that the likelihood of MCI occurrence increased by 9% when the hearing threshold exceeded 20 decibels.ConclusionThis study provides evidence from genomic and epidemiological investigations indicating that hearing loss may serve as a risk factor for cognitive impairment. While our epidemiological study has found both hearing loss and tinnitus as potential risk factors for cognitive decline, additional research is required to establish a causal relationship, particularly given that tinnitus can manifest as a symptom of various underlying medical conditions.

Project description:OBJECTIVES:To describe the basic demographical characteristics of whole blood donors in Zhejiang Province, China, from 2006 to 2015 and to examine the trends in individual characteristics associated with blood donation and the relationship between weight and donation. DESIGN:Cross-sectional study comparing characteristics of blood donors and annual donations for the period 2006 to 2015. SETTING:Urban and rural communities in Zhejiang, China (11 cities, 89 districts or counties and 1379 townships). PARTICIPANTS:3 226 571 volunteer blood donors. OUTCOME MEASURES:Volume of each whole blood donation and donation frequency. All data were collected by trained staff and entered into a standardised electronic information system. RESULTS:The number of blood donations generally trended up in Zhejiang Province from 2006 to 2015. Donors were predominately males aged 18 to 25 years, but this major donor age group shifted to the 26 to 45 year range by 2015. The rate of repeated blood donation was 30.8 per cent. The blood volume per donation concentrated in 200 mL and 400 mL categories has been gradually shifted to 300 mL and 400 mL. Approximately one-third of donors had a college education. The average weight of donors increased over time for both men and women. Both the blood volume of each donation and donation frequency were proportional to weight. CONCLUSIONS:The trend of voluntary non-remunerated blood donation in Zhejiang province is positive. However, given the expected growth in demand for whole blood, more research is needed to increase both the donor pool and the rate of repeated donation. The relationship between body weight and blood donation warrants further study because while improving nutritional status is associated with higher average donation volume and more frequent donations, overnutrition may lead to poorer quality of donated blood. Blood donation may present a unique opportunity for health education and body weight management to monitor and improve population health.

Project description:ObjectiveTo investigate the prevalence and correlating factors of binge drinking among middle and high school students in Zhejiang Province, China.MethodsWe performed a cross-sectional study using data from a school-based survey. A total of 23 543 (response rate=97.5%) eligible adolescents from 442 different schools (including middle schools, academic high schools and vocational high schools) were asked to fill in an anonymous self-administered behaviour questionnaire between April and May 2017. Multivariable logistic regression models were used to examine the associations of sociodemographic and behavioural factors with binge drinking.ResultsThe mean (SD) age of participants was 15.6 (1.7) years and 51.3% were boys. The proportions of students from middle schools, academic high schools and vocational high schools were 51.9%, 27.5% and 20.6%, respectively. In total, 22.8% (95% CI 21.6 to 23.9) of students reported drinking alcohol in the past 30 days and 9.2% (95% CI 8.5 to 10.0) of students reported binge drinking (defined as drinking four or more alcoholic drinks in 1-2 hours period among girls and five or more alcoholic drinks among boys) during the past month. The prevalence of binge drinking was highest among vocational high school students (17.9% vs 6.3% and 7.7% among middle school and academic high school students, respectively). Older age, studying at high school, poor academic performance, higher levels of physical activity, excessive screen-time, loneliness, insomnia, previous suicide attempt, cigarette smoking, fighting, being bullied and sexual experience were found to be positively associated with adolescent binge drinking.ConclusionsBinge drinking is common among middle and high school students in Zhejiang, China. Efforts to prevent binge drinking may need to address a cluster of sociodemographic and behavioural factors. Our findings provide information to enable healthcare providers to identify students at high-risk of binge drinking and to inform planning of intervention measures for at-risk students.
