Résumé : |
The uterus undergoes dramatic hypertrophic growth during pregnancy and efficient function of this muscular organ is essential for achieving safe birth outcomes for pregnant patients and neonates. Current scientific discourse on the uterine structure and function demonstrates that poor contractile capacity of the uterus at term is strongly correlated with complications including prolonged labour and labour dystocia, fetal distress, vacuum or forceps-assisted deliveries, caesarean section and postpartum haemorrhage.
Though such complications and interventions contribute to poor maternalfetal outcomes, reduce maternal satisfaction with the birth experience and increase cost of care, current research has not explored what modifiable factors affect the ability of the uterus to develop optimally during pregnancy. While much is known about what factors affect the body's ability to synthesise new skeletal muscle, almost nothing is known about what is needed to support uterine hypertrophy during gestation. Skeletal muscle hypertrophy requires adequate protein intake and synthesis, and micronutrient availability. It is reduced by the diabetic environment, obesity and age. All of these factors are also correlated with birth outcomes related to uterine function, though the direct mechanism has not been elucidated. It is likely that the muscle tissue of the uterus is affected by the same factors that mediate skeletal muscle hypertrophy: when these factors are optimal, adequate uterine hypertrophy can occur during gestation and effective contractile function is present at term. Drawing on an array of literature from several fields of study, this article explores the factors known to influence skeletal muscle hypertrophy and hypothesises links to the muscular development of the uterus during pregnancy and resultant birth outcomes. The factors presented in this article are well known to influence both skeletal muscle hypertrophy and birth outcomes related to the contractile function of the uterus. They include maternal dietary protein intake, vitamin D status, blood sugar control, obesity, gestational weight gain and age. Optimising the factors that are modifiable may serve to improve the safety of birth through improved uterine muscle development during pregnancy. |
