Obesity in adult male offspring. a Body weight of offspring from LF- and HF-fed dams who were weaned onto LF diet for 5 weeks and then fed either LF or HF diet from week 8 until week 20 (three-way ANOVA with repeated measures: maternal diet effect, p < 0.0001; postweaning diet effect, p < 0.0001; time effect, p < 0.0001; time × maternal diet, p = 0.0001; postweaning diet × maternal diet interaction, p < 0.0001; n = 12 per group except D-HF/O-HF group, n = 16. Post-hoc Bonferroni, ab*, p < 0.0001 compared with all other groups; ab, p < 0.0001 compared with D-LF/O-LF and D-LF/O-HF; a, p < 0.01 compared with D-LF/O-LF). b Body weight gain from 8 to 20 weeks of age (two-way ANOVA: postweaning diet effect, ‡‡‡‡P < 0.0001; post-hoc Tukey’s test, n = 12 per group except D-HF/O-HF group, n = 16). c Average daily calorific intake of offspring (three-way ANOVA with repeated measures: maternal diet effect, p < 0.0001; postweaning diet effect, p < 0.0001; time effect, p < 0.0001; time × maternal diet interaction, p = 0.0161; time × postweaning diet interaction, p < 0.0001; maternal diet × postweaning diet interaction, p < 0.0001; time × maternal diet × postweaning diet interaction, p = 0.0181; n = 12 per group except D-HF/O-HF group, n = 16. Post-hoc Bonferroni, ab*, p < 0.0001 compared with all other groups; a, p < 0.05 compared with D-LF/O-LF; b
p < 0.001 compared with D-LF/O-LF). d Feeding efficiency of offspring fed with either LF or HF diet for 12 weeks (two-way ANOVA: postweaning diet effect, ‡‡P = 0.0013; post-hoc Tukey’s test, n = 12 per group except D-HF/O-HF group, n = 16). e Epididymal fat pad weight (two-way ANOVA: maternal diet effect, P < 0.0001; postweaning diet effect, P < 0.0001; post-hoc Tukey’s, n = 12 per group except D-HF/O-HF group, n = 16), Subcutaneous fat pad weight (two-way ANOVA: maternal diet effect, P = 0.0002; postweaning diet effect, P = 0.0258; post-hoc Tukey’s, D-LF/O-LF, n = 5; D-HF/O-LF, n = 12; D-LF/O-HF, n = 12; D-HF/O-HF, n = 16) and mesenteric fat pad weight (two-way ANOVA: postweaning diet effect, ‡P = 0.0107: D-LF/O-LF, n = 12; D-HF/O-LF, n = 12; D-LF/O-HF, n = 10; D-HF/O-HF, n = 16). f Plasma leptin levels in the offspring at week 20 (n = 10 per group except D-HF/O-HF group, n = 8). Data are shown as mean ± SEM. *P < 0.05, **P < 0.01, ***P < 0.001, ****P < 0.0001
