PrimeScreen diet quality scores for intervention and control groups at 3 gestational stages of pregnancy
| Gestational stage (wk) | Intervention (n = 55)1 | Control (n = 56)2 | 
|---|---|---|
| 12–173 | 18.7 ± 7.6a | 17.7 ± 8.7 | 
| 26–28 | 22.9 ± 6.1b | 18.7 ± 7.7 | 
| 36–38 | 22.5 ± 6.9c | 18.7 ± 8.5 | 
Values are mean ± SD.
Intervention: a vs. b, P < 0.001; a vs. c, P < 0.008; as analyzed using generalized estimating equations adjusted for maternal prepregnancy body mass index and study site.
Control: no differences across time points as analyzed by generalized estimating equations adjusted for maternal prepregnancy body mass index and study site.
Measures taken before intervention initiated.
