Associations of television viewing and computer use with cognitive performance in older adults: A cross-sectional NHANES study

= 0.030), with smaller positive associations observed for CERAD. RCS analyses indicated a nonlinear association for computer use, with peak cognitive benefits at approximately two hours per day, while TV viewing showed a linear negative relationship. Associations were robust across age, sex, and race subgroups and in sensitivity analyses.ConclusionsIn older adults, longer TV viewing was associated with lower verbal fluency, whereas moderate computer use was associated with better processing speed. A non-linear association was observed for computer use, with benefits peaking at around 2 h per day.
