Childhood Nutrition Can Positively Influence Social Behaviors and Development

Emerging research suggests good nutritional intake during childhood has a positive effective on early childhood development.

The study was led by two University of Pennsylvania researchers: Jianghong Liu, an associate professor in Penn’s School of Nursing and Perelman School of Medicine, and Adrian Raine, the Richard Perry University Professor of Criminology, Psychiatry, and Psychology.

Their study provides a unique perspective on a field that often focuses on how poor diet negatively influences early childhood development. The study results appear in the journal Maternal & Child Nutrition.

“What people are not doing is looking at positive effects of good nutrition, in particular on social behavior,” said Raine.

“We link nutrition to physical health but also social health and positive social behavior.”

Liu said it’s a gap in the research she hopes this work might bridge. “No one has looked at positive social behavior,” she said.

“Childhood social behavior, even adult social behavior, has a lot of implications for physical and mental health and well-being.”

For this study, the scientists analyzed a sample of 1,795 3-year-old children from Mauritius, an island off the eastern coast of Africa with a population of about 1.3 million people. They focused on four aspects of physical health related to nutrition and four indicators of social development.

Physical health factors are medical issues that can include anemia, expressed by low hemoglobin levels that reflect iron deficiency. Another condition is angular stomatitis revealed by cracked lips and a lack of vitamin B2 and niacin. And a third is sparse hair or hair discoloration as a result of insufficient protein intake.

On Mauritius, where the majority of children have black hair, the fourth factor shows up as an orange or red tint to the hair.

The researchers considered a child with just one of the quartet as “suffering from nutritional deficits.” However, children with more malnutrition indicators showed more impaired social behavior.

Social interactions studied included friendliness, extent of verbalization, active social play, and exploratory behavior.

To assess a child’s abilities, a research assistant observed every child’s success and rated these factors on a specified scale.

The observer knew that the research concentrated on child development and behavior but was unaware of the nutrition-related hypothesis.

Examining the relationship between these components after the fact, Liu and Raine discovered a statistically significant link between nutrition and comprehensive social behavior. The neurocognitive relations was undiscovered to this point.

“The bigger message is give children good nutrition early on,” Liu said. “Not only will it enhance cognitive function but, importantly, promote good social behavior,” which is essential to brain development and intelligence.

“In the same study,” Raine said, “we’ve shown that children with positive social behavior, eight years later, they have higher IQs.”

Despite the diversity of Mauritius, which has Indian, Creole and, to a smaller extent, Chinese, French and English populations, the researchers acknowledge a desire to replicate their findings in large cities in the United States.

Another limitation is the study’s cross-sectional nature, meaning measurements occurred all at once rather than over a long period of time.

Ideally, Raine said, “you want a randomized control trial. You want to manipulate nutrition to see whether you can get improvements in social behavior and cognitive function.”

It’s possible to reverse the effects of poor nutrition, too, according to the researchers.

“It’s never too late to provide good nutrients,” Liu said.

“And it’s never too early,” Raine added.
