Body mass index values for newborns according to gestational age. Capuurro 1M. The combination of twho anthropometric parameters has been more appropriate to assess body composition and proportions in children, with special attention to the Body Mass Index BMIas it relates weight and length. However the BMI values for the neonatal period have not been determined yet. This study edav the BMI for newborns at different gestational ages represented in a normal smoothed percentile curve.

Retrospective study including 2, appropriate for gestational age newborns following the Alexander et al curve from 29 to 42 weeks of gestational age. Weight and lenght were measured following standard procedures.

For the construction aof a normal smoothed percentile curve, the 3 rd5 th10 th25 th50 th75 th90 th and 95 th percentiles were determined and a statistical procedure based on the mathematical model “sinosuoidal fit” was gestacipnal to establish a curve that estimates biological growth parameters. The Body Mass Index values for gestational age in all percentiles shows a steady increase up to 38 weeks, levels off up to the 40 th week, followed by a slight decrease to the 42 nd week in both genders.

The results show a direct correlation between gestational age and Body Mass Index for both genders in the nine percentiles, and can provide a useful reference to assess intra-uterine proportional growth. En un estudio retrospectivo incluyendo 2. The nutritional assessment of the capurrk has been a challenging issue and any deviation from the normal is associated with an increased risk of morbidity and mortality.

They are important for reflecting intrauterine growth and for defining a baseline for infants’ nutritional follow-up. A single standard anthropometric factor, as the measure of simple weight, cannot assess the nutritional status of the newborn properly. This report aims to present references for the Body Mass Index of the newborn at different gestational ages in both sexes and to construct a normal smoothed percentile curve. Exclusion criteria were newborns with impaired fetal growth or abnormalities such as hydrops fetalis, congenital malformations, congenital infection or multiple births.

To avoid the influence of unhealthy or growth restricted newborns due to unknown causes, the Alexander et al curve 8 was adopted as a pre-classification criteria and weight and length measurements below the 10 th percentile and above the 90 th percentile were also excluded.

The weight and length measurements were obtained using standard pediatric measurement procedures 9. The weight was determined when the baby was born; using a digital scale with an accuracy of 0.

The length assessment was performed using a wood length board with a fixed headpiece and a movable footpiece, perpendicular to the surface of the table. One of the pediatricians held the infant’s head and the other held the infant’s feet against the footboard, applying a gentle pressure to extend the infant’s legs so that the heels of the infant touched the footboard firmly.

To establish an accurate gestational age for each infant, the date of the last normal menstrual period was considered first, followed by the gestational age based on the first trimester ultrasonographic measurement and finally confirmed by the postnatal examination method Capurro for term infants and New Ballard for the preterms. The infants were grouped according to their gestational age, which was conventionally expressed as completed weeks.

The overall sample size was determined by the need to obtain sufficient data for valid calculation of percentile values from 29 to 42 weeks, totaling 2, infants. The BMI was calculated based on the formula: For the construction of the normal smoothed percentile curve, first the real BMI values for each percentile were ordered and the graphic model was analyzed. The distribution obtained fitted the mathematical model “sinusoidal fit”, as this mathematical model corresponded to the equation that best represented a biological parameter of growth and at the same time had a higher determination coefficient R 2 in all the calculated percentiles with lower residuals errors.

Through this formula exad corresponding prediction values were calculated, smoothing the possible skew of the distribution and determining the final curve. Sex differences for BMI in each gestational age were tested using the Students’ t-test.

Finally, gsstacional validity of BMI as a good index of overweight and underweight depends on its degree of independence from length.

The dataset included 2, infants, consisting of 1, boys and 1, girls, for gestational ages between 29 and 42 weeks. Table I and II give the BMI references for each gestational age in the studied percentiles 3, 5, 10, 25, 50, 75, 90, gdstacional and The 50 th percentile for BMI is 8. The Pearson’s correlation coefficients of BMI with length were very low, ranging from The final Body Mass Index curves for each gestational age in all percentiles show a steady increase up to 38 weeks, then a leveling off up to the 40th week, followed by a slight decrease in the 42 nd week figs.

Despite technological advances, anthropometric parameters continue ppr represent lor most practical method of assessing nutritional status and grstacional in the pediatric years, particularly during the neonatal period. In general, the classification of newborn infants, by plotting their anthropometric parameters as birth weight, length and head circumference on standard growth curves, has provided pediatricians with information regarding the risk of neonatal mortality and metabolic complications such as hypoglycemia and polycythemia.

The anthropometric parameters are important in reflecting intrauterine growth and to define a edav to follow-up the nutritional progress of the infant. Many authors have proposed that the assessment of body proportions may be more useful than single measurements for age alone for assessing newborn nutrition.

Weight adjusted for height provides a measure of the percentage body fat for older ages and many weightfor-length indexes have been proposed for this purpose. This index provides a gestacionzl estimate of body fat mass as it has a positive correlation with skinfold thickness and other methods of estimating the percentage of body fat, for example the bioelectrical impedance and densitometry. Furthermore, this index takes advantage of the physiologic principle regarding sparing length at pof expense of weight during mild to moderate malnutrition.

The Body mass index has been intensely gstacional for nutritional assessment in adolescents and adults, and has already been validated for children from 0 to 36 months as a good way to evaluate adiposity and body proportions. The validity of body mass index as an index of overweight and underweight depends on its degree of independence from length, 6,7 gesatcional at each gestational age group, the Pearson’s correlation coefficient of BMI with length was tested. The results obtained were very low, ranging from Many previous studies have shown concern about the correlation between birth weight, and intrauterine growth restriction, with clinical risk factors for cardiovascular diseases, including hyperlipidemia, elevated insulin and high blood pressure.

The construction of a BMI curve for newborns at different gestational ages can be used to track body proportions through life and may complement the nutritional assessment for this period. The presented curves show a steady growth of the BMI values for both sexes up to 38 weeks, then level off up to 40 weeks and is followed by a slight decrease in the 42 nd gestational week. This pattern can be explained considering that in late gestation the fetal growth is constrained by maternal and placental factors.

It might be a useful parameter for newborn classification, helping in the detection of intra-uterine growth disturbances and also assisting to validate the nutritional therapy through the time.
