For specific ages and genders, published LMS data (WHO reference and standard) were used to generate smoothed centiles 3, 10, 25, 50, 75, 90, and 97 (−2 to +2 SD) for height-for-age, BMI-for-age (2 19y), length-for-age, length-for-weight, and head circumference-for-age (0 2y).
Our findings indicate that rate of gestational weight gain was significantly associated with infant birth (weight and length) and growth outcomes at 6 months of age (weight for age, length for age, weight for length z scores weight gain velocity).
Their anthropometrical measures a year later were compared to the WHO sex-specific growth standards for weight-for-age, length-for-age, weight-for-length, and BMI-for-age.
Primary outcome was infant anthropometric indicators at 6 months of age (weight for age, length for age, weight for height z scores), and infant weight gain velocity during the first 6 months of life.
Based on the collected data, we calculated z scores for length-for-age, weight-for-age, weight-for-length/height, head circumference-for-age and body mass index (BMI -for-age among offspring according to the growth curves puBMI -for-ageHO in 2006.
The main birth characteristics are presented in Table 1. 1 Standard deviation The infant size at the age of follow up was analysed using weight- and length-for-age, weight-for-length, and BMI (weight/length -for-age as measures.
Mean Z-scores at 6, 9, 12 and 18 months for length-for-age, weight-for-age and weight-for-length will be determined as well as changes in Z-scores over 12 months.
Growth was assessed according to weight for age, length for age, weight for length and head circumference for age.
Postnatal somatic growth (measured, eg, using anthropometry (head circumference, weight-for-age, height or length-for-age, weight-for-height, BMI-for-age, mid-upper arm circumference, child growth rate)).
All parameters and covariates are based on units (m) for length, (kg) for weight, (L) for volume and (min) for time, unless otherwise stated.
The distributions of length-for-age, weight-for-length and BMI in late infancy of children born at term in central delivery clinics in the Khanh Hoa province in Vietnam deviate from the WHO standards.
