Association Between Omega-3 Supplement Use and Cognitive Function in Korean Older Adults: An 8-Year Longitudinal Cohort Study.

ABSTRACT:

Objectives

South Korea has a relatively high baseline omega-3 fatty acids (O3FA) status due to dietary patterns. However, evidence on additional benefits of O3FA supplementation remains limited. This study examined the 8-year longitudinal effects of O3FA supplement use on cognitive performance among community-dwelling older adults in South Korea.

Design

Prospective longitudinal cohort study.

Data were from the Korean Longitudinal Study on Cognitive Aging and Dementia (KLOSCAD). A total of 4,949 adults aged ≥60 years (mean age = 69.55 ± 6.56; 44.2% men) were included, and 2,053 completed the 8-year follow-up (2010-2012 to 2018-2020).

Measurements

O3FA supplement use was assessed through structured questionnaires on regular intake of omeg
