Cross-sectional associations of sedentary behaviour and physical activity on depression in Japanese older adults: an isotemporal substitution approach.

ABSTRACT:

Objectives

Reducing sedentary behaviour (SB) and increasing physical activity (PA) have been shown to be associated with decreased depression. However, there are yet few studies examining the potential benefits on older adults' depression, when SB is replaced with PA. This study aimed to examine the associations of objectively assessed SB, light-intensity PA (LPA) and moderate-to-vigorous PA (MVPA) with depression among a sample of Japanese older adults, and to explore impacts of substituting SB with PA on older adults' depression.

Design

Cross-sectional analysis.

Setting

General community.

Participants

A total of 276 older adults aged 65-85 years living in Japan.

Main outcome measures

Three behaviours including the average daily time spent in SB (≤1.5 M
