Abstract

Objective:

Interventions currently recommended to control and prevent obesity have not been successful. Recent research has shifted towards the transgenerational cycle of obesity. We assessed the association between fetal macrosomia and early childhood body weight.

Methods:

We conducted a follow-back study to link birth certificate data to the Third National Health and Nutrition Examination Survey (1988-1994) of 2621 United States-born singletons aged 2–6 years. Birth weight and gestational age data were collected from birth certificates. Fetal macrosomia was defined as ≥ 90 th percentile of gestational age-race-sex-parity specific bodyweight distribution in 1989 vital statistics.

Results:

With 12.7% (0.85%) of participants born macrosomic, the prevalence of obesity and overweight (BMI percentiles ≥ 85 th in the CDC growth chart) among children was 17.8% (standard error = 1.17%). When the body weight was measured against age-sex specific height (BMI percentiles), macrosomia was significantly associated with overweight and obesity (odds ratio [OR]= 1.64, 95% confidence interval [CI]= 1.07–2.50) adjusted for family income, maternal age and marital status, race, maternal smoking during pregnancy, and breastfeeding. The association became insignificant after adjusting for postnatal lifestyle and parental body mass index (OR = 1.38 (0.84 - 2.26)]. When body weight was measured against age, children who were too heavy for their age were more likely to be born macrosomically [OR=2.64 (1.66 - 4.22)] than their peers with healthy age-specific body weight.

Conclusion:

Fetal macrosomia was significantly associated with a doubled risk of heavy body weight in children aged 2–6 years.
