OBJECTIVE: To study the impact of cardiovascular diseases (CVDs) on hearing deterioration among ageing adults in a longitudinal setting. Furthermore, to describe the pure tone threshold changes at the 0.125-8 kHz frequency range over 13 years. DESIGN: A population-based follow-up study. STUDY SAMPLE: A random sample of 850 adults, of whom 559 participated in the follow-up study. Otological examination, a structured interview, and pure tone audiometry were conducted. Multivariate regression models were used to estimate the effect of CVD (participants had at least one cardiovascular condition) on hearing deterioration of the better ear hearing level (BEHL), defined as a change in the pure-tone average (PTA) of the frequencies 0.5, 1, 2, and 4 kHz and separately at the lower (0.125, 0.25, and 0.5 kHz) and higher (4, 6, and 8 kHz) frequencies. RESULTS: In the multivariable-adjusted analysis, the BEHL change at 13 years was 0.7 dB greater among participants with CVD (p = 0.3). The mean BEHL change during the 13-year follow-up was 12.0 dB (95% CI 11.4-12.6) among all participants.

OBJECTIVE: The aim of this study was to investigate the prevalence and incidence of hearing impairment (HI) in a longitudinal setting among adults. DESIGN: An unscreened, population-based epidemiological 13-year follow-up study. Study sample: 850 randomly sampled 54 to 66-year-old baseline participants, of whom 559 participated in the follow-up study at the age of 68 to 79 years. A questionnaire-based interview, an otological examination and pure-tone audiometry were performed. RESULTS: The overall prevalence of HI was 70.3%, defined by better ear hearing level (BEHL) ≥ 20 dB in the 0.5-4 kHz frequency range. The prevalence was higher among men (78.6%) than among women (63.7%). The overall incidence rate for HI was 45.8 per 1000 person years and the 13-year cumulative incidence was 60.9%. The incidence was higher among men and older participants. CONCLUSION: HI is highly prevalent and incident among older adults in Northern Finland., Funding Agencies:Finnish State Research funding Yrjo Jahnsson Foundation Paivikki and Sakari Sohlberg Foundation Finnish Society of Audiology

The Saami are the only indigenous population in Europe and their traditional living area is northern Scandinavia. Hearing impairment (HI) among Saami has not been studied before. The objective was to investigate the presence and type of HI among Saami adults, aged 49-77 years (median age 61 years), living in northern Finland. In addition, the presence of self-reported hearing difficulties, difficulties to hear in background noise and tinnitus were studied. An epidemiological, cross-sectional study encompassing a structured interview, otological examination and audiometry was performed. Bilateral HI was present in 42.9% of men and 29.4% of women, when HI was defined as a pure tone average (PTA) of at least 20 dB hearing level (HL) or more at the frequencies of 0.5, 1, 2 and 4 kHz. In one or both ears (worse ear hearing level, WEHL0.5,1,2,4≥20 dB HL) HI was present in 61.8% of men and 42.2% of women. Sensorineural high frequency hearing impairment was found to be most common. Nearly half (46.9%) of the study subjects reported hearing problems and more than half (55.6%) reported difficulties in following conversation in background noise. Measured HI and subjective hearing difficulties are common among the Saami adults. The healthcare personnel working in this area should be aware of the hearing problems of the Saami population.

Objective: To investigate the influence of cardiovascular diseases on hearing impairment (HI) among adults. Furthermore, to seek other potential risk factors for HI, such as smoking, obesity, and socioeconomic class. Design: A cross-sectional, unscreened, population-based, epidemiological study among adults. Study sample: The subjects (n = 850), aged 54-66 years, were randomly sampled from the population register. A questionnaire survey, an otological examination, and pure-tone audiometry were performed. Results: Cardiovascular diseases did not increase the risk for HI in a propensity-score adjusted logistic regression model: OR 1.24, 95% CI 0.79 to 1.96 for HI defined by better ear hearing level (BEHL), and OR 1.48, 95% CI 0.96 to 2.28 for HI defined by worse ear hearing level (WEHL), in the 0.5-4 kHz frequency range. Heavy smoking is a risk factor for HI among men (BEHL: OR 1.96, WEHL: OR 1.88) and women (WEHL: OR 2.4). Among men, obesity (BEHL, OR 1.85) and lower socioeconomic class (BEHL: OR 2.79, WEHL: OR 2.28) are also risk factors for HI. Conclusion: No significant association between cardiovascular disease and HI was found., Funding Agencies|Oulu University Hospital; European ARHI Project [QLRT-2001-00331]
