Disease activity index (DAI) is the combined score of weight loss, stool consistency, and bleeding.
Independent variables were BMI classes, the scores of somatic and mental diseases, the BES grade, and the score of weight history.
Briefly this involved obtaining the z score of weight for height (difference between weight and mean weight for height, relative to standard deviation), adjusting this by adding a constant that depended on stage of gestation, and then recalculating a weight only from this adjusted z score.

Underweight, stunting, and wasting were defined as < − 2 z score of weight-for-age (WAZ), height-for-age (HAZ), and weight-for-height z-scores (WHZ), respectively.
► The journal Cell Metabolism retracted a 2014 paper in which researchers announced "that they had discovered how grizzly bears gain scores of weight before hibernation, but avoid the obesity-associated health problems," Hanae Armitage reported in a third Tuesday ScienceInsider.
Just more than a year ago, researchers published a paper announcing that they had discovered how grizzly bears gain scores of weight before hibernation, but avoid the obesity-associated health problems, such as diabetes, that typically accompany such dramatic weight gain in people.
Based on the effect size of 0.5 standard deviation (SD) of difference between the average Z-score of weight at 12 months of age, level of significance of 5% and test power of 80%, was calculated 72 mother-child pairs per group and 144 pairs in the control group, summing up a total 432 pairs calculating a loss to follow up of 20%, the size of the final sample consists of 521 mother-child pairs.
Since use of standardised scores of weight and length rather than raw measurements makes local and international comparisons easier, growth measurements were standardised to generate z-scores using the 2006 WHO reference population [ 28].
The final model can be written as (for example, for fetal weight): SD score of fetal weight = β0 + β1× gawks + β2× exposure group + β3× gawks × exposure group (gawks = gestational age in weeks).
Primary outcomes were birth weight, Z-score of birth weight, placental weight, and placental ratio.
In this study, we found that changes of Hb levels from early pregnancy were significantly inversely associated with birth weight, Z-score of birth weight, placental weight, and placental ratio in pregnant Japanese women.
