Abstract:
Objective Maternal dietary modifications determine the susceptibility to metabolic diseases in adult life.However, whether maternal high-fat diet can induce early-onset aberrant glucose and lipid metabolism in offspring mice is less understood .Materials and Methods We examined the effects of feeding the pregnant mice with either a high fat diet or nornal chow diet throughout pregnancy and lactation on the glucose and lipid metabolism in their offsprings . Some glucose and lipid metabolism biomarkers and hepatic histology were analyzed .Results At weaning, for males of dams fed high-fat diet , they had heavier body weight , the blood glucose levels were significantly higher at 30 min ( P<0.001) and 60 min (P<0.01) after intraperitoneal glucose administration , and the AUC was also significantly larger (P=0.0016) and HOMA-IR was higher(P<0.05).For females of dams fed high-fat diet, they had higher blood glucose levels at 30 min ( P<0.01 ) after intraperitoneal glucose administration .No significant differences were observed of AUC and HOMA-IR.Both males and females of dams fed high-fat diet had elevated total cholesterol levels ( P<0.0001 and P=0.0004, respectively).Triglyceride levels showed no significant differences between the two groups of males and females . The offsprings of high-fat diet group indicated hepatic steatosis and there were no differences between males and females . Conclusions Maternal high fat diet during pregnancy and lactation can induce early -onset aberrant glucose and lipid me-tabolism in offspring mice , and the male offsprings are more prone to metabolic changes , such as obesity , glucose intoler-ance and insulin resistance .
