Association between the Infant and Child Feeding Index (ICFI) and nutritional status of children aged 6 to 35 months in Coastal Cities of Fujian Province, China
This study of 1,807 children in Fujian Province, China, found that while the Infant and Child Feeding Index (ICFI) effectively reflects population-level feeding practices and socioeconomic disparities, its utility for predicting individual child growth outcomes is limited due to a weak correlation with nutritional status.

Imagine you are trying to judge how well a young child is being fed. You could look at their growth chart (like checking if a plant is tall enough), or you could look at their daily menu (checking if they are getting the right ingredients). This study from Fujian Province, China, tried to see if a specific "menu checklist" called the Infant and Child Feeding Index (ICFI) is a good predictor of how well a child is actually growing.
Here is the breakdown of what the researchers found, using simple analogies:
The "Menu Checklist" (The ICFI)
Think of the ICFI as a report card for a child's diet. Instead of just asking "Did they eat?", this index gives points for:
- Breastfeeding: Is the child still nursing?
- Variety: Are they eating different types of food (like meat, eggs, beans, and grains)?
- Frequency: How often are they eating these foods?
The researchers gave this "report card" to nearly 1,800 children aged 6 months to 3 years old. They wanted to see if a high score on this menu checklist meant the child was growing well.
What the Checklist Scored
The average score was decent (about 8 out of 13), but it wasn't perfect. The researchers noticed a few clear patterns:
- Age Matters: Older toddlers (12–35 months) got much higher scores than babies (6–8 months). It's like a teenager getting an "A" on a homework assignment while a kindergartener gets a "C" on the same test; the older kids just have more experience with solid foods.
- The "Address" Factor: Kids living in cities scored higher than those in the countryside.
- The "Mom" Factor: Children whose mothers had more education or were slightly older (31–40 years old) tended to have better diet scores.
- Money Matters: Higher household income was linked to better scores.
Basically, the checklist was very good at showing who had better resources and knowledge. If a family had more money, lived in a city, and the mom had a college degree, the child's "menu score" was usually excellent.
The Big Surprise: The Checklist vs. The Growth Chart
This is the most important part of the study. The researchers compared the "Menu Score" (ICFI) against the child's actual physical growth (measured by height and weight charts, known as Z-scores).
- The Expectation: They hoped that a high menu score would mean a tall, healthy child.
- The Reality: The connection was very weak.
- For the younger babies (6–11 months), there was no link at all between a good diet score and how they were growing.
- For the older toddlers (12–35 months), there was a tiny, barely noticeable link between a good diet score and their weight, but nothing for their height.
The Analogy: Imagine two runners. Runner A has a perfect training plan (high ICFI score). Runner B has a messy training plan (low ICFI score). You might expect Runner A to be faster. But in this study, the researchers found that having the "perfect plan" didn't guarantee the runner was actually faster. Other things—like genetics, hidden illnesses, or how much sleep they got—were just as important, if not more so.
The Conclusion
The study concludes that the ICFI is a great tool for looking at a whole group of people to see if there are gaps between rich and poor, or city and country. It tells us, "Hey, families with more education are feeding their kids better."
However, it is not a great tool for predicting if a specific child will grow tall or strong. Just because a child has a high "menu score" doesn't automatically mean they are growing perfectly, and a low score doesn't guarantee they are failing to grow.
The Takeaway:
The researchers suggest that while we should keep using this checklist to spot families who need help with their feeding knowledge (especially in rural areas and for younger babies), we shouldn't rely on it alone to judge a child's health. We still need to look at the child's actual growth chart and consider other factors like genetics and health, not just what they ate on paper.
