ObjectivesTo assess the prevalence of overweight/obese children and to explore body composition in a Swedish cohort of preschool children born with marginally low birth weight (MLBW, ie, 2000-2500Â g).Study designWe included 285 Swedish children with MLBW (44% small for gestational age), and 95 control children with normal birth weights. At 3.5Â years and 7Â years of age, we assessed anthropometrics, including the prevalence of overweight/obese children. At 7Â years, dual-energy X-ray was used for body composition.ResultsThere were no significant differences between groups in the prevalence of overweight/obesity or in skinfold thickness; however, at 3.5Â years, mean height, weight, and BMI in children with MLBW were 2.1Â cm (95% CI 1.2-3.1), 1.2Â kg (95% CI 0.7-1.6), and 0.47Â kg/m2 (95% CI 0.17-0.76) lower compared with controls. The corresponding mean differences also were lower in children with MLBW compared with control children at 7Â years; 2.5Â cm (95% CI 0.9-4.1), 1.6Â kg (95% CI 0.6-2.8), and 0.48Â kg/m2 (95% CI 0.01-0.94). The differences were greater in those born small for gestational age. Dual-energy X-ray analyses showed lower fat-free mass index in MLBW infants and a similar trend in fat mass index. Within children with MLBW, BMI at 7Â years correlated positively to growth velocity in infancy.ConclusionChildren with MLBW had lower BMI and did not show increased risk of overweight or obesity up to 7Â years. Nevertheless, the BMI in MLBW children was positively correlated to growth-velocity in infancy.Trial registrationClinicaltrials.gov: NCT00558454.
