macrosomia
Unfavourable birth weight, as characterised by either low birth weight (<2500 g) or macrosomia (>4000 g), accounts for approximately 20 % of births worldwidePregnancy is a critical time for caution about diets. Maternal dietary habits can have a direct effect on the growing fetusAnother health behaviour during pregnancy that may influence birth weight is sedentary behaviour, which is mainly attributed to prolonged screen time. With an escalation in the use of digital technologies over the last two decades, prolonged and excessive screen time has become a public health concern. The increased sedentary time during pregnancy is associated with higher levels of LDL-cholesterol in mothers and a larger newborn abdominal circumference. However, its association with child birth weight remains inconclusiveA better understanding of the association between maternal dietary and sedentary behaviours during pregnancy and birth weight will inform future health promotion interventions. Research on the association between mothers’ dietary and sedentary behaviours and birth weight is scarce and results are inconclusive. To address this knowledge deficit, this study investigated whether mothers’ dietary and sedentary behaviours during pregnancy are associated with their children’s birth weight outcomes.
