Comparing Attained Weight and Weight Velocity during the First 6 Months in Predicting Child Undernutrition and Mortality.

ABSTRACT:

Background

The first 6 mo of life are critical for subsequent risk of undernutrition and mortality. The predictive abilities of attained weight at the end of each month and monthly weight velocity for undernutrition and mortality need to be compared.

Objectives

This study aimed to examine the predictive abilities of different weight metrics during the first 6 mo of life in predicting undernutrition and mortality.

Methods

This study used a cohort of infants in Tanzania. Weight and length were measured monthly from birth to 18 mo of age. Three weight metrics during the first 6 mo of life were considered as predictors, including attained weight-for-age z score (WAZ) at the end of each month, monthly change in WAZ, and monthly weight velocity z score (WVZ). Logistic models were used with undernutrition (at 6 or 12 mo) and mortality (over the first 18 mo) as outcomes. AUC values were compared across metrics.

Results

For predicting wasting at 6 mo, WVZ (AUC: 0.80) had a greater predictive ability than attained WAZ (AUC: 0.76) and change in WAZ (AUC: 0.71) during the second month of life. After 2 mo, attained WAZ (AUC: 0.81-0.89) had greater predictive abilities than WVZ (AUC: 0.71-0.77) and change in WAZ (AUC: 0.65-0.67). For predicting stunting at 6 mo, attained WAZ (AUC: 0.75-0.79) had consistently greater predictive abilities than WVZ (AUC: 0.56-0.66) and change in WAZ (AUC: 0.50-0.57). The weight metrics had similar abilities in predicting mortality, with the AUC rarely reaching >0.65.

Conclusions

Attained weight at the end of each month had greater abilities than monthly weight velocity in the same month in predicting undernutrition. Attained weight remains a useful indicator for identifying infants at greater risk of undernutrition.

Project description:Background and objectivesStudies in low-and middle-income countries where nutrition transition is underway provides mixed evidence of double burden of maternal overnutrition and child undernutrition among mother-child pairs. Shifting dietary pattern and rapid increase in overweight/obesity among adults with persistent child undernutrition indicate that India is experiencing nutrition transition and double burden of malnutrition. Hence, the study explores the presence of and the factors associated with mother-child dyads of over- and undernutrition in India.Methods and materialsThe study uses National Family Health Survey 2015-16 data. The analytic sample consists of 28,817 weighted mother-child pairs where an overweight/obese mother is paired with an undernourished child. The nutritional status of children is defined according to WHO 2006 child growth standards as underweight (i.e., low weight-for-age), stunting (i.e., low height-for-age) and wasting (i.e., low weight-for-height). Maternal overweight/obesity (i.e., BMI ≥ 25 kg/m2) is defined using adult BMI criterion. Descriptive, bivariate, and adjusted multivariable logistic regression analysis are conducted.ResultsOf the overweight/obese mothers, 21.3%, 26.5%, and 14% have underweight, stunted, and wasted children respectively. In adjusted models, maternal short stature (aOR: 2.94, 95% CI: 2.30-3.75), age of child (aOR: 3.29, 95% CI: 2.76-3.92), and poorest wealth status (aOR: 2.01, 95% CI: 1.59-2.54) are significant predictors of overweight/obese mothers and stunted child pairs. Similarly, poor wealth status (aOR: 1.68, 95% CI:1.32-2.14), maternal stature (aOR: 2.70, 95% CI: 2.08-3.52), and child aged 2-5 years (aOR: 1.77, 95% CI:1.51-2.08) are also significantly associated with higher occurrence of overweight/obese mother and-underweight child pairs.ConclusionFindings of the study are consistent with the phase of nutrition transition and double burden of malnutrition. The paper concludes with suggestions to improve the socioeconomic condition, more strategic nutrition specific investments and policy interventions to eliminate all forms of malnutrition for achieving SDGs.
