At every YHC routing check out (in the guy age circa 0, 1, 2, step 3, 4, 6, nine, a dozen few days), child weight and height try measured using standardized actions of the YHC nurses . We put kid lbs aspect within kid period of circa 0, 3, six, and nine months. To adjust lbs to own psychological growth and you may intercourse differences, the weight-for-many years z-score (WAZ) have been determined using the Dutch 1997 years- and you will sex-particular reference thinking. Kids putting on weight in almost any date windows (0–3 months, 0–half a year, and you can six–one year) try examined by the changes in WAZ among them date-activities. A rise in WAZ of greater than 0.67 from inside the whenever windows is actually recognized as quick putting on weight.[eight, 27]
