Infant and Young Child Feeding Practices Assessment
Also known as: IYCF, WHO IYCF Indicators
The IYCF assessment is a set of core indicators developed by WHO and UNICEF to measure the prevalence of key feeding practices in children aged 0–23 months. The indicators track six essential markers: exclusive breastfeeding in infants under 6 months, continued breastfeeding in the second year, timely introduction of complementary foods at 6–8 months, and adequate dietary diversity and meal frequency by 6–23 months. These indicators are foundational for monitoring nutrition outcomes and evaluating maternal and child health programs worldwide.

When to use it
IYCF indicators are the standard for monitoring infant and young child nutrition in national surveys, program evaluations, and research. Use in Demographic and Health Surveys (DHS), Multiple Indicator Cluster Surveys (MICS), and population-based prevalence studies. Appropriate for mothers and caregivers of children aged 0–23 months in any country or setting. Essential for baseline and endline measurement in maternal, newborn, and child health programs, including breastfeeding promotion, complementary feeding counseling, and nutrition supplementation initiatives. Recommended for all child nutrition surveillance and evaluation activities.
Strengths & limitations
- WHO/UNICEF-endorsed standard; globally comparable indicators used in 100+ countries.
- Based on strong evidence of links between feeding practices and child nutrition/health outcomes.
- Feasible for large-scale population surveys; brief, standardized questions minimize respondent burden.
- Binary indicators are simple to interpret and communicate to non-technical audiences.
- Sensitive to program interventions; documented responsiveness to breastfeeding promotion, complementary feeding education, and food assistance.
- Integrated into major global surveys (DHS, MICS); enables comparison with international benchmarks.
- Relies on maternal recall; subject to forward/backward telescoping bias (respondents may misremember ages and timelines).
- Does not capture feeding quality or safety; dietary diversity does not ensure micronutrient adequacy for individual children.
- Does not measure food quantity, energy intake, or individual-level food distribution within household.
- 24-hour dietary recall masks seasonal and temporal variation; single day may not represent usual feeding pattern.
- Dietary diversity threshold of ≥4 food groups is population-average target; individual child may be inadequately nourished despite diversity.
- Does not assess breastfeeding exclusivity at individual meal level; relies on maternal recall of liquid supplements.
Frequently asked
What is the difference between exclusive breastfeeding and continued breastfeeding in the IYCF indicators?
Exclusive breastfeeding (indicator 1) means the child receives ONLY breast milk—no formula, water, water-based liquids, or solid/semi-solid foods—and is measured in children <6 months. It is a binary yes/no based on the previous 24 hours. Continued breastfeeding (indicators 2 and 3) means the child is still receiving breast milk at 12–15 months and 20–23 months, regardless of other foods. Continued breastfeeding can coexist with complementary foods and formula; exclusive breastfeeding cannot.
How do I determine if a child meets minimum dietary diversity if they eat snacks, not structured meals?
Minimum dietary diversity counts all foods and drinks consumed in the past 24 hours, regardless of meal structure. Include foods eaten as meals, snacks, street foods, and shared family dishes. Ask systematically about each food group (grains, legumes, dairy, meat/poultry, eggs, vitamin-A vegetables/fruits, other vegetables/fruits) and code yes if any food from that group was consumed. Snacks and small portions count equally to main meals.
What happens if a child aged 12–15 months is never breastfed? How do I score continued breastfeeding?
If a child was never breastfed (formula-fed from birth), the continued breastfeeding indicator is scored 'no' because the child is not receiving breast milk at 12–15 months. Continued breastfeeding is a yes/no indicator with no 'not applicable' option; 'no' covers both children who stopped breastfeeding and children never breastfed. This is correct scoring; the prevalence of continued breastfeeding will be low in populations with high early formula adoption.
How do I score minimum meal frequency for a 6-month-old who is starting complementary foods?
At 6 months, if the child is breastfed, minimum meal frequency is ≥2 meals/snacks of solid or semi-solid complementary food per day (plus breast milk). If not breastfed, the target is ≥3 meals/snacks. Ask the mother how many times yesterday the child ate complementary foods (not counting breast milk). If breastfed and ate ≥2 meals, score yes. If not breastfed and ate ≥3 meals, score yes.
