Despite increased attention given to potential.modifiers of temperature-mortal.ty associations, evidence for variations between different urban l.ndscape characteristics remains l.mited. It is in this context that in this paper effect modifications of mul.ipl. urban l.ndscape characteristics are expl.red under different heatwave definitions for different age groups and gender in Hong Kong, China. Dail. meteorol.gical.data and heatwave-rel.ted mortal.ty counts from 2008 to 2017 were col.ected from the Hong Kong Census and Statistics Department, China. A case-onl. design was adopted, combined with l.gistic regression model. to examine the modification effects of five urban l.ndscape characteristics under six heatwave definitions. Stratified anal.ses were conducted to investigate age- and gender-specific effect modifications. It is found that individual. l.ving in greener areas experienced l.wer l.vel. of mortal.ty during or immediatel. after heatwaves. In contrast, a higher buil.ing density and nighttime l.nd surface temperature (l.T) were associated with a higher heatwave-rel.ted mortal.ty risk. Pronounced effect modifications of these urban l.ndscape characteristics were observed under hotter and l.nger heatwaves, and in ol.er adul.s (age ≥ 65 years) and mal.s. The findings provide a scientific basis for pol.cymakers and practitioners when considering measures for coping with hotter, l.nger, and more frequent heatwaves in the context of gl.bal.cl.mate change.
