A recent study led by scientists at the University of Hawai’i (UH) at Mānoa highlights concerning nutritional patterns among children aged two to eight years across 11 Pacific jurisdictions, including Alaska, American Samoa, the Commonwealth of the Northern Mariana Islands, the Federated States of Micronesia, Guam, Hawai’i, the Marshall Islands, and Palau. The research reveals that these children are either consuming excessive or insufficient amounts of key micronutrients, which has serious implications for their health.
The study, which also examined the relationship between micronutrient intake, obesity, and the skin condition acanthosis nigricans—a known indicator of insulin resistance—points to crucial gaps in the region’s nutritional landscape.
Lucia Seale, associate professor at the Pacific Biosciences Research Center in UH Mānoa’s School of Ocean and Earth Science and Technology, and Ashley Yamanaka, assistant director of the Children’s Healthy Living Center of Excellence, co-led the study. Seale emphasized the importance of early childhood nutrition in shaping long-term health, noting that while macronutrient excesses (like carbohydrates and fats) are often blamed for obesity, micronutrient imbalances also play a significant role. “Understanding the relationship between micronutrient intake and obesity can guide interventions aimed at addressing the region’s nutritional needs,” Seale stated.
Uncovering Micronutrient Imbalances
Prior research has focused on the micronutrient intake of adults in the United States-Affiliated Pacific (USAP) region, but this new study marks the first to explore how micronutrient levels relate to childhood obesity and overall health. The research team analyzed food intake data collected by the Children’s Healthy Living (CHL) Center, a collaborative initiative dedicated to improving nutrition and health across the Pacific. The data, gathered over several years, provides a comprehensive look at the eating habits of children in the region.
The study found that many Pacific children have inadequate intakes of essential nutrients like calcium, potassium, vitamin D, and vitamin E. At the same time, they are consuming too much sodium, folate, vitamin A, and niacin. These imbalances are linked to higher rates of obesity and acanthosis nigricans, a condition commonly associated with type 2 diabetes.
Seale and Yamanaka, along with collaborators from various universities and research centers, identified key nutritional disparities. “Pacific children with obesity had higher intakes of thiamin (vitamin B1) and lower intakes of selenium compared to their peers without obesity,” Seale explained. “Interestingly, their selenium levels were still above recommended daily intake guidelines, despite being considered excessive.”
Widespread Concerns About Excess Sodium
One of the most alarming findings was the widespread consumption of excessive sodium. According to the study, 95% of children in high-income areas of the Pacific, including Hawai’i, were consuming too much sodium, posing serious risks to their cardiovascular health. Additionally, 97% of children in these areas were not getting enough vitamin D, which is essential for bone health and immune function.
The study also found that 13% of children in these high-income areas consumed excessive amounts of selenium, a mineral commonly found in seafood and certain soils. While the high selenium intake is likely due to dietary patterns in Hawai’i, Seale expressed concern about the potential health risks associated with overconsumption.
Tailored Interventions for Improved Nutrition
The research not only highlights critical nutrient imbalances but also suggests that more tailored dietary recommendations are necessary for the diverse Pacific jurisdictions. By analyzing nutrient intake data in relation to local income levels, the researchers propose a foundation for future programs and policies, such as school meal initiatives and trade regulations.
“The findings underscore the need for targeted interventions to address sodium reduction and improve overall nutritional intake,” Seale said. “This study provides valuable data that can inform strategies for improving childhood nutrition and long-term health in Pacific communities.”
The researchers emphasize that any nutritional programs or policies must be culturally and socioeconomically relevant to the region. By ensuring these strategies are grounded in scientific evidence, the study paves the way for future efforts aimed at improving the health and well-being of children across the Pacific.
In conclusion, this research not only contributes to our understanding of the nutritional challenges faced by children in the Pacific but also lays the groundwork for more effective, region-specific solutions. As Seale noted, “This study represents an essential first step in shaping policies that reflect the unique needs of our communities, reinforcing UH’s commitment to research that drives meaningful change.”
