RDA Harmonization in SEA

1997: ILSI SEA called for a better understanding of RDAs in
the region
1998: Agreed on a framework for harmonization
The goal of the harmonized
RDAs was to obtain consensus
among the SEA countries on:
1. Definition of RDAs for SEA
2. Minimum list of core nutrients
3. Population age groupings
4. Reference body weights
Protein quality: NPU = 70 for Malaysia, Philippines, Singapore; protein usage = 60 for
Vietnam; digestibility of 85% for Thailand;

This was achieved by adopting a lower maintenance
value (90 mg nitrogen/kg per day) and replacing the 50%
increase in the protein allowance for growth to cover
day-to-day variation with an increase in the coefficient
of variation for growth.
The growth rates assumed were derived from the WHO
1994 breastfed pooled dataset (WHO 1994)
The efficiency of utilization of dietary protein for growth
was again assumed to be 70%.

The reference weights for infants and children up to 5 years are
the median values of the WHO Multicentre Growth Reference
Study Group (2006) for weight-for-age to achieve growth
potential.
The median weight-for-height and median height-based BMI
were used for the 6-9 years and 10-18 years, respectively, using
the median height of Filipino child with normal nutritional

Stunting is a chronic form of undernutrition that results from
some combination of prenatal and postnatal linear growth
faltering.
Infants who are born with a low birth weight are
particularly vulnerable to frequent infections and
malnutrition, which result in linear growth faltering and
poor cognitive development.
The severe irreversible physical and neurocognitive damage
that accompanies stunted growth is a major barrier to human
development.

The Impact of Nutritional Interventions beyond the First 2 Years
of Life on Linear Growth: A Systematic Review and Meta-Analysis
Roberts, JL and AD Stein; Adv Nutr 2017;8:323 36.
The aim of this analysis was to evaluate the effectiveness of
several nutrition-based interventions, specifically iron, zinc,
calcium, iodine, vitamin A, multiple (> 2) micronutrients, protein,
and food, at improving growth in children above 2 y of age.
Zinc (mean effect size: 0.15; 95% CI: 0.06, 0.24), vitamin A
(0.05; 95% CI: 0.01, 0.09), multiple micronutrients (0.26; 95%
CI: 0.13, 0.39), and protein (0.68; 95% CI: 0.30, 1.05) had
significant positive effects on linear growth, with baseline
height-for-age z score as a significant inverse predictor of the
effect size.

Association between maternal intake of n-6 to n-3 fatty acid
ratio during pregnancy and infant neurodevelopment at 6
months of age: results of the MOCEH cohort study
Hyejin Kim et al Nutrition J 16:23, 2017
The recommended dietary n-6/n-3 PUFAs ranges from 5:1 15:1 in
Europe and from 4:1 10:1 in the United States and South Korea
Conclusions: Both the maternal dietary n-6/n-3 PUFAs and
LA/ALA intake were significantly associated with the mental
and psychomotor development of infants at 6 months of age.
Thus, maintaining low n-6/n-3 PUFAs and LA/ALA is encouraged
for women during pregnancy.

Recommendations
In both adults and children, WHO
recommends reducing the intake of
*free sugars to less than 10% of total
energy intake (strong
recommendation).
the intake of free sugars to below 5% of
total energy intake (conditional
recommendation).
2015
(2015)
*Free sugars include monosaccharides and disaccharides
added to foods and beverages by the manufacturer, cook or
consumer, and sugars naturally present in honey, syrups, fruit
juices and fruit juice concentrates.

Evidence of dietary intake of children meeting the
recommended quantity and quality of protein?
Evidence of health benefits in infants and young children
provided with the recommended n-6/n-3 PUFAs ratios?
Evidence of the applications of the Acceptable
Macronutrient Distribution Range values in improving the
nutritional status of young children
