Viet Nam: Prevalence of wasting, weight for height (% of children under 5)

Key figures

What the numbers say

In 2023, Viet Nam's prevalence of wasting, weight for height (% of children under 5) did not change 0 percentage points on 2022 (from 4.4% to 4.4%).

Across the 19 yearly changes before that (1994 to 2022), the average change was −0.13 percentage points and a typical year strayed about 2.32 percentage points from that (the standard deviation). This year's change was 0.1 standard deviations above that average, so it was an ordinary year: it sits within the range of normal year-to-year movement.

On record, the biggest yearly rise was 6.8 percentage points in 1994 and the biggest yearly fall was 4.8 percentage points in 2000. The numbers show how large and when, not why; for the cause, look at what happened in that country in those years.

From 2014 to 2023 the straight-line trend is downward, about 0.28 percentage points a year. A straight line explains 97% of the movement over 8 observed years.

What this measures

Prevalence of wasting is the proportion of children under age 5 whose weight for height is more than two standard deviations below the median for the international reference population ages 0-59 months.

Limitations: Survey estimates come with levels of uncertainty due to both sampling error and non-sampling error (e.g., measurement technical error, recording error etc.,). None of the two sources of errors have been fully taken into account for deriving estimates neither at country nor at regional or worldwide levels. Surveys are carried out in a specific period of the year, usually over a few months. However, this indicator can be affected by seasonality, factors related to food availability (e.g., pre-harvest periods), disease (e.g.,rainy season and diarrhoea, malaria, etc.), and natural disasters and conflicts. Hence, country-year estimates may not necessarily be comparable over time.

Regional and income-group figures are computed by the World Bank as a linear mixed-effect model estimates.
