Outcome | LFD | HFD |
---|---|---|
First pregnancy | n = 18 | n = 8 |
Body weight (g) | 5.8 ± 0.2 | 7.4 ± 0.8* |
Body length (snout to vent) (mm) | 48.0 ± 0.8 | 53.5 ± 1.4* |
Body mass index (kg/m2) | 2.48 ± 0.06 | 2.53 ± 0.17* |
Second pregnancy | n = 33 | n = 7 |
Body weight (g) | 5.9 ± 0.1 | 8.9 ± 0.3*† |
Body length (snout to vent) (mm) | 49.1 ± 0.6 | 56.7 ± 1.0*† |
Body mass index (kg/m2) | 2.47 ± 0.04 | 2.77 ± 0.09*§ |
There was a significant effect of both diet (p < 0.001*) and pregnancy (p < 0.035†) on offspring body weight and length (2-way ANOVA) with no significant interactions (p < 0.299). There was a significant effect of diet only (p < 0.001§) but not pregnancy (p = 0.169) on offspring BMI (2-way ANOVA) with no significant interaction (p = 0.131)
From 4 weeks of age, C57Bl/6 J female mice (n = 28) were separated into 2 treatment groups and fed either a low fat diet (LFD, n = 14) or high fat diet (HFD, n = 14). Female mice were mated with male C57Bl/6 J mice after dams were fed either diet for 12 weeks. Three weeks later, offspring were born. Dams were re-mated 1 week after their first litters were removed at 2 weeks of age. All measures were obtained from offspring at 2 weeks of age. Data are shown as mean ± SEM
