Table 4. Association of stunting status at 2, 5 and 9 years and verbal, performance and total IQ scores at 9 years of age using regression analysis (n = 200#).
| Predictors | Adjusted beta co-efficient (95% CI) | ||
|---|---|---|---|
| Verbal IQ | Performance IQ | Total IQ | |
| Stunting | |||
| Children who were never stunted | 1 | 1 | 1 |
| Stunted at 2 years and catch-up at 5 years | -0.20 (-3.70–3.29) | -5.77 (-10.51 - -1.03) | -3.00 (-6.65–0.66) |
| Stunted at 2 and 5 years, and, catch-up at 9 years | -1.79 (-5.27–1.69) | -0.88 (-5.60–3.85) | -1.33 (-4.97–2.31) |
| Stunted at 2, 5 and 9 years | -4.61 (-8.86 - -0.36) | -4.64 (-10.41–1.14) | -4.62 (-9.07 - -0.17) |
| Socio economic status at 2 years | |||
| Low (<33rd percentile of WAMI) | 1 | 1 | 1 |
| High (> = 33rd percentile of WAMI) | 5.13 (2.27–7.98) | 4.91 (1.04–8.79) | 5.02 (2.04–8.01) |
| Mother’s IQ scores | 0.18 (0.06–0.31) | 0.33 (0.16–0.49) | 0.26 (0.13–0.38) |
IQ–Intelligence Quotient; WAMI–Water, Assets, Maternal Education and Income
#200/203(98.52%) children who had complete information on stunting at all three time points were included in this analysis.
Bolded values have significant p-values
R2 values for regression models with following outcomes -verbal, performance and total IQ scores were 14.88%, 13.96% and 17.06% respectively.
