Association of large for gestational age with cardiovascular metabolic risks: a systematic review and meta‐analysis

Abstract

AbstractObjectiveThe aim of this study was to clarify the relationships among large for gestational age (LGA) and cardiometabolic risk factors.MethodsPubMed, Web of Science, and the Cochrane Library databases were searched to identify studies on LGA and outcomes of interest, including BMI, blood pressure, glucose metabolism, and lipid profiles. Data were independently extracted by two reviewers. A meta‐analysis was performed using a random‐effects model. The Newcastle‐Ottawa Scale and funnel graph were used to assess the quality and publication bias, respectively.ResultsOverall, 42 studies involving 841,325 individuals were included. Compared with individuals born appropriate for gestational age, individuals born LGA had higher odds of overweight and obesity (odds ratios [OR] = 1.44, 95% CI: 1.31‐1.59), type 1 diabetes (OR = 1.28, 95% CI: 1.15‐1.43), hypertension (OR = 1.23, 95% CI: 1.01‐1.51), and metabolic syndrome (OR = 1.43, 95%; CI: 1.05‐1.96). No significant difference was found in hypertriglyceridemia and hypercholesterolemia. Stratified analyses showed that, compared with individuals born appropriate for gestational age, individuals born LGA had higher odds for overweight and obesity from toddler age to puberty age (toddler age: OR = 2.12, 95% CI: 1.22‐3.70; preschool: OR = 1.81, 95% CI: 1.55‐2.12; school age: OR = 1.53, 95% CI: 1.09‐2.14; puberty: OR = 1.40, 95% CI: 1.11‐1.77).ConclusionsLGA is associated with increased odds of obesity and metabolic syndrome later in life. Future studies should focus on elucidating the potential mechanisms and identifying risk factors.
