(US) (n = 17), Australia (n = 12) and United kingdom (UK) (n = 10). The mean age on the participants ranged from four.five to 76.5 years. A total of 5 studies included only people aged 55 years or older [226]; 11 research incorporated only people today below 16 years old [277]. Most research have been balanced in gender distribution, with proportions of female participants ranging from 32 to 67 . 4 studies exclusively examined female participants [381]. Cities and inner-city neighbourhoods were the predominant settings. Seven research took location in multi-ethnic and/or socioeconomically deprived regions [291,37,424]. A single study specifically examined the differential impact of green space on young children of South Asian descent versus Caucasian kids [37].
