Percent differences in cortisol reactivity and cortisol recovery rate by SES trajectory
| Cortisol Measure | Model 1a | Model 2b | ||
|---|---|---|---|---|
|
| ||||
| % Diff | 95% CI | % Diff | 95% CI | |
| Stress Reactivity (vs. Stable high) | ||||
| Downward mobility | −2 | (−15, 42) | 3 | (−11, 44) |
| Upward mobility | −6 | (−16, 39) | −1 | (−13, 41) |
| Stable medium | −8 | (−23, 41) | −1 | (−17, 44) |
| Stable low | −6 | (−19, 40) | −4 | (−17, 41) |
| Recovery Rate (per hour; vs. Stable high) | ||||
| Downward mobility | 30 | (7, 58) | 35 | (9, 61) |
| Upward mobility | 23 | (4, 53) | 27 | (7, 56) |
| Stable medium | 13 | (−12,53) | 14 | (−12, 54) |
| Stable low | 35 | (9, 61) | 46 | (15, 68) |
For reactivity, a positive point estimate indicates higher reactivity (i.e., a larger increase in cortisol). For recovery rate, a positive point estimate indicates slower recovery (i.e., a less negative hourly change in cortisol).
Bold indicates p < .05 compared to stable high SES.
a
Unadjusted.For global test of model fit compared to model excluding lifetime SES trajectory indicators, mean p-value across imputations = .14 (range .04-.29).
b
Adjusted for age, gender, race/ethnicity, and nativity. For global test of model fit compared to model excluding lifetime SES trajectory indicators, mean p-value across imputations = .03 (range .003-.10).
