*Numbers show the estimated total effects (considering both main and interactive effects) of heat exposure for each subgroup. These estimates were calculated through linear combinations of coefficients from the growth curve models detailed in online supplemental table2; All models were adjusted for race/ethnicity, neighbourhood SES, sex, living arrangement, educational attainment, household wealth, region of residence, urbanicity and years of follow-up. **p<0.01.
SES, socioeconomic status.
