摘要
Objective To evaluate the associations between selected birth characteristics-prematurity and poor intrauterine growth-and risk factors for coronary artery disease detected among children enrolled in the fifth grade. %26lt;br%26gt;Study design Children (n = 3054) with matched birth and fifth grade health screening data on body mass index (BMI), systolic blood pressure, and fasting lipid profiles were analyzed using MANOVA with the following independent variables of weight gain by the fifth grade: BMI percentile, normal or overweight/obese (BMI %26gt;= 85th percentile), prematurity, and intrauterine growth (ie, small for gestational age [SGA], appropriate for gestational age [AGA], or large for gestational age [LGA]). %26lt;br%26gt;Results LGA status at birth was associated with overweight/obesity later in life. In fifth grade, overweight/obese children had elevated systolic blood pressure and abnormal levels of most fasting serum lipids compared with normal-weight children regardless of birth characteristics. Beyond the effects of BMI percentile, preterm infants had higher levels of triglycerides (TG) than term infants by the fifth grade (P %26lt; .05). SGA infants who become overweight/obese had higher levels of TGs and very low-density lipoproteins compared with AGA and LGA infants, whether overweight or normal weight (P %26lt; .05). %26lt;br%26gt;Conclusion BMI %26gt;= 85th percentile in the fifth grade is associated with abnormalities in most coronary artery risk factors regardless of birth characteristics. Beyond the effects of BMI percentile in the fifth grade, preterm infants had higher TG levels than term infants. SGA infants who were overweight/obese in the fifth grade had higher TG and very low-density lipoprotein levels compared with AGA and LGA infants who were overweight/obese or of normal weight in the fifth grade.
