• PGE could improve QoL, especially for physical domain • PGE was associated with anxiety among males and those aged 45-60 • PGE was not associated with stress • Access of greenspace was associated with physical domain of QoL • Access of greenspace was associated with anxiety and depression : This study aims to explore the association of perceived greenspace exposure (PGE) with quality of life (QoL) and mental health among non-healthcare workers. : A cross-sectional survey of non-healthcare workers was conducted in Hong Kong from March 2023 to December 2024. Information was collected by online questionnaires. We measured PGE using a 7-point Likert self-reported questionnaire about greenspace abundance, visibility, access and usage near participants’ neighborhood/workplace. We assessed relationships between PGE with QoL and mental health using generalized linear and logistic regression models, and restricted cubic spline regression with four knots was used to examine the dose-response relationship. : Among 1380 non-healthcare workers, 547 (39.6%) were male, the mean physical composite score (PCS) was 46.1 (standard deviation SD: 8.34) and the mean mental composite score (MCS) was 50.6 (14.59). We found 300 (21.7%) participants with stress symptoms above DASS-21 cut-off, 512 (37.1%) with anxiety symptoms above DASS-21 cut-off and 419 (30.4%) with depression symptoms above DASS-21 cut-off. Positive relationships between PCS and four PGE domains (ß=0.29, 95% CI: 0.03-0.54 for PGE1; 0.41, 0.18, 0.64 for PGE2; 0.45, 0.21-0.70 for PGE3 and 0.33, 0.09-0.58 for PGE4), and between MCS and PGE3 (0.54, 0.11-0.96) were observed. Besides, higher PGE3 was associated with lower odds of anxiety (odds ratio OR=0.93, 95% confidential interval CI: 0.87-0.99) and depression (OR=0.93, 95% CI: 0.87-0.99). Subgroup analyses showed that PGE played different roles on workers among different genders and ages. : PGE is associated with better quality of life and mental health. Urban planning should prioritize not only greenspace quantity but also, critically, its perceived accessibility near workplaces and neighborhoods.
