Abstract

Objective: This study aimed to describe infant growth patterns using attained growth z-scores and growth velocity z-scores in the first year of life in Indonesia. Method: A cohort study of 359 newborns was conducted in 2015-2017 in Yogyakarta, Indonesia. Weight and length were routinely measured throughout the first year of life to calculate the attained growth z-scores (weight-for-age/WAZ, length-for-age/LAZ, and weight-for-length z-scores/WLZ) and growth velocity z-scores (weight velocity/WVZ and length velocity z-scores/LVZ). Undernutrition was categorized into underweight (WAZ<-2), stunting (LAZ<-2), and wasting (WLZ<-2). Growth faltering was categorized into weight faltering (WVZ<5th centile) and length faltering (LVZ<5th centile) using WHO child growth standards. Results: The proportion of undernutrition and growth faltering varied throughout infancy. The highest proportion of undernutrition was the proportion of stunting at 12 months (15.3%) which was two times higher than at birth (7.3%). The highest proportion of weight and length faltering was in 4-6 months with 28.6% and 39.4%, respectively. Median WAZ was relatively stable at around -0.30 SD in the first six months before it slightly decreased to -0.64 SD at 12 months of age. Median LAZ increased from -0.62 SD at birth to -0.23 SD at four months before declining to -0.83 SD at 12 months. In comparison to attained growth z-scores, growth velocity z-scores depicted an opposing pattern. Median WVZ decreased from 0.33 SD at 0-2 months to -0.80 SD at 4-6 months, while median LAZ dropped from 1.33 SD at 0-2 months to -1.20 SD at 6-9 months. Conclusion: The proportions of undernutrition and growth faltering were relatively high in the first year of life. Growth velocity z-scores showed an earlier downward pattern than attained growth z-scores. Therefore, routine monitoring, particularly in growth velocity z-scores, might allow earlier detection and treatment of child growth faltering.

Abstract

Purpose: To describe the prevalence of weight faltering, wasting, and stunting in infancy and explore their associations. Methods: This secondary analysis used a 2015-2017 birth-longitudinal cohort study in Yogyakarta, Indonesia. Mean Z-scores for weight-for-age (WAZ), length-for-age (LAZ), and weight-for-length (WLZ) were presented. Weight faltering, wasting, and stunting were assessed. Weight faltering refers to a deceleration in weight that crosses two major percentiles relative to the 2006 WHO Child Growth Standards, evaluated at 0-6 and 6-12 months. Wasting is defined as WLZ<-2 SD, while stunting is LAZ<-2 SD. The association between weight faltering and undernutrition at 6 and 12 months was explored using logistic regression. Results: This study included 294 of 422 participants from the original cohort study. The prevalence of wasting and stunting peaked at 7 months (13%, 6/45) and at 12 months (17%, 25/150), respectively. Weight faltering at 0-6 months (10%, 28/293) was higher than in 6-12 months (4%, 10/250). Bivariate analysis showed that weight faltering at 0-6 months was significantly associated with wasting at 6 months (OR 10.89, 95% CI 3.41-34.80, p-value<0.001) and at 12 months (OR 7.17, 95% CI 1.53-33.49, p-value=0.027), but not with stunting. Conclusion: The prevalence of weight faltering and wasting was higher at 6-7 months of life, whereas stunting was higher at 12 months. Despite showing no significant association with stunting, infants with weight faltering have a higher risk of wasting. Identification of weight faltering is essential to signal the need for further clinical investigation and to enable early intervention to prevent the onset of wasting.
