Abstract

Relationship between adult height and cognitive impairment remains unclear. The present study used data collected during the 2019 Korea Community Health Survey. The study population was composed of 150,742 persons aged ≥ 40 years, and the study outcome was subjective cognitive decline (SCD). Covariates included comorbidities, health-related habits, social status, mental health, social contact, and family history of dementia. Approximately one in five subjects presented with SCD, which was more frequent in women. Factors associated with SCD varied by gender. A multivariate regression model revealed that height was significantly related to SCD in men but not in women even after adjustment for covariates.
