“…This was the first large population-based study to provide a clinical association between olfactory dysfunction and mental health [31] . To analyze the association between olfactory dysfunction and mental health such as depressive symptoms and suicidal thoughts in South Korea, using data from the 2010–2011 KNHANES, Joo et al found that the prevalence of olfactory dysfunction was 5.0% (ages ≥ 19 years) [32] .…”

“…Essentially all studies show that the prevalence of decreased olfactory function increases very significantly with age [26, 32, 34, 36] . Which portion of the age range that is included in the study affects this phenomenon.…”

“…Both KNHANES and OLFACAT found that olfactory dysfunction was significantly associated with education level [32, 36] . For example, in OLFACAT, a low educational level was a risk factor for problems with smell detection, smell recognition/memory (middle school OR 1.2, 95% CI, 0.56–2.6; high school OR 0.84 95% CI, 0.72–0.97; university OR 0.93 95% CI, 0.83–1.04) and smell identification (middle school OR 0.49, 95% CI, 0.21–1.16; high school OR 1.01 95% CI, 0.88–1.15; university OR 1.21 95% CI, 1.09–1.34) [36] .…”

“…A few studies showed that depression is associated with olfactory dysfunction [30, 32] . In the KNHANES, for example, the participants with olfactory dysfunction were at higher risk for a depressed mood (OR1.505, 95% CI, 1.106–2.048) and suicidal thoughts (OR 1.306, 95% CI, 1.027–1.662).…”

Participants with olfactory dysfunction had a higher risk of mental disease than did participants without olfactory dysfunction, and this relationship persisted even after further adjustment for depressive mood [32] . In MAP, we found that more loneliness was associated with worse odor identification (OR per 1 SD, 0.78, 95% CI 0.69–0.88).…”

Insights into risk factors for olfactory decline are needed, because knowledge about its origin is limited. This impairment has important implications for human health. Several epidemiologic studies of olfaction provide insight into the prevalence of olfactory disorders. Here, we review the major population studies carried out on this topic to date. Our purpose is to characterize knowledge about olfactory disorders from human studies. We also describe the existing methods for measuring the sense of smell in population studies, present recent insights into the epidemiology of smell disorders, and discuss the risk factors identified to date. Synthesis of these data shows that olfactory dysfunction increases as people age and is worse in men. Further study of olfaction is warranted for gaining better information on the etiologies affecting its impairment, research that will have a large public health impact.
