Sentence examples for a given birthweight from inspiring English sources

20 Where the number of studies reporting a given birthweight standard and outcome allowed, we performed subgroup analysis to examine the effect of potential confounding factors.

For a given birthweight, South Asian babies born in India have been found to be fatter (as measured by subscapular and triceps skinfolds or cord-blood leptin levels) than white European babies born in Europe or the USA [ 7– 9].

We address a number of methodological issues related to our proposal, including the construction of confidence intervals for mortality risk at any given birthweight within a component, for odds ratios comparing mortality within two different components from the same population, and for odds ratios comparing mortality within analogous components from two different populations.

For example, Leonard, et al. (2007) [ 16] and Hutton, et al. (2007) [ 17] used the ratio of the observed birthweight to the expected birthweight for a given gestational age to assess fetal growth, whereas Leitner, et al. (2007) [ 15] and Gortner, et al. (2003) [ 19] classified all infants with birthweights below the 10th percentile as small for gestational age at birth.

Newborns classified as small-for-gestational age (SGA) were defined by a birthweight lower than the 10th percentile of birthweight distribution for a given gestational age and sex, according to French reference curves [ 22].

This definition is also easier to apply than that based on birthweight percentile for a given gestational age.

Using the concept of birthweight percentile at a given gestational age (i.e., LGA) as the definition of macrosomia has been proposed in recent years [ 2, 10, 21].

The population-specific definition of macrosomia using birthweight cut-off points irrespective of gestational age (4500 g in Africa and Latin America, 4000 g in Asia) is more predictive of maternal and perinatal adverse outcomes, and simpler to apply compared to the definition based on birthweight percentile for a given gestational age.

As it is increasingly recognized that racial variation in birthweight is substantial, more and more studies are using specific birthweight percentiles as cut-off points at a given gestational week (e.g., P90 or P97) based on the concept of large-for-gestational-age (LGA) [ 2, 10].

18 We defined births with a birthweight for gestational age of five or more standard deviations above or below the mean for a given gestational age as misclassified.

A birthweight cut-off points irrespective of gestational age (4500 g in Whites, 4300 g in Blacks and Hispanics) is more predictive of mortality and morbidity outcomes than the 97th percentile for a given gestational age.
