Mariska Stam started working as a PhD-student at the department of Otolaryngology-Head and Neck surgery, section Ear & Hearing of VU University Medical Center/EMGO+ Institute in September 2010. Her project concerned “National Longitudinal Study on Hearing (NL-SH), second wave”. The aim of this prospective cohort study is to examine the (longitudinal) relationship between hearing impairment and various aspects of life, such as work, psychosocial health, quality of life and use of health care. More information can be found on the website of the project www.hooronderzoek.nl.


Mariska may defend her PhD dissertation, entitled "How hearing impairment may impact adult life: Baseline and 5-year follow-up results of the NL-SH study" on June 10th, 2015 at 13:45 hrs at VU University in Amsterdam. This thesis covers a series of studies each providing news insights into how hearing impairment may impact the lives of adults, and into the determinants and consequences of a deterioration in speech recognition ability over time. Baseline and 5-year follow-up data of the web-based NL-SH study were used. It is the first time that deterioration of speech intelligibility in noise over years was investigated at such a large scale. The following major conclusions are as follows:

  • Diabetes relates to impaired hearing ability. We found associations between poor speech recognition ability in noise and 1) self-reported diabetes, and 2) self-reported diabetes medication
  • Adults with poor speech recognition ability in noise aged 18 to 64 years have a relatively poorer socioeconomic status than their normally hearing peers as indicated by paid work, educational level, and income
  • On average, for the total group of adults aged 18 to 70 years, a small numeric deterioration in speech recognition ability was found over five years. However, deterioration of speech recognition ability seems to accelerates at the age of 50
  • Over time, poorer hearing ability status was related to more feelings of loneliness and a deterioration over time was related for some subgroups of participants to increased

Hearing impairment can thus negatively impact different domains of life. Continuation of the NL-SH study and other longitudinal epidemiological studies in hearing is indispensible to better understand the mechanisms underlying for instance the relationship between diabetes and hearing problems. Longitudinal studies additionally provide us with important insights about the process of hearing deterioration over the life span. Currently, a next follow-up measurement in the NL-SH study (10-years after baseline) will be therefore prepared.


Currently, Mariska continues her scientific work at the department of Otolaryngology-Head and Neck Surgery, section Ear & Hearing of VU University Medical Center as a post-doc researcher co-supervising the NL-SH study.
