Early Weight Gain: Height Boost, Not Obesity Risk
- New research indicates that increasing weight in undernourished children during their first decade can lead to significantly taller adult stature.
- The findings are notably relevant for children facing undernutrition, offering a chance to improve their long-term health and development.
- Beverly Strassmann,a University of Michigan professor of anthropology,led the study.
Groundbreaking research flips the script on childhood weight gain. This study reveals that early weight gain in undernourished children,between ages 1 and 10,actually boosts adult height. Researchers followed over 1,300 participants for two decades and found no significant correlation between weight gain and increased obesity or high blood pressure risk later in life. This challenges existing nutritional intervention guidelines that frequently enough cease after age two. The findings highlight the importance of considering the long-term benefits of childhood weight increases, offering hope for improved health outcomes.

Childhood Weight gain Can Boost Adult Height, Study Shows
Updated June 24, 2025
New research indicates that increasing weight in undernourished children during their first decade can lead to significantly taller adult stature. The study, published in JAMA Network Open, found no significant increase in the risk of obesity or high blood pressure later in life.
The findings are notably relevant for children facing undernutrition, offering a chance to improve their long-term health and development. Researchers followed 1,348 participants in central Mali for 21 years, tracking weight gain from ages 1 to 10 and its impact on adult height.
Beverly Strassmann,a University of Michigan professor of anthropology,led the study. She noted that previous recommendations suggested interventions after age 2 might not be beneficial, due to concerns about increased blood pressure and obesity. However, Strassmann said this neglected the importance of weight gain for achieving full height potential.
The study revealed that weight gain between ages 1 and 10 was significantly associated with increased adult height for both males and females by age 21. Strassmann emphasized the importance of considering both the risks and benefits of childhood weight gain.
Strassmann also highlighted the unique longitudinal design of the research, which followed children from an average age of 1.6 years to 21 years. She said this is rare for low-income countries in Africa.
”Our findings are significant because they show that improved growth from age 1 to 10 years led to taller stature in adulthood and the increased risk for obesity and hypertension was negligible,” Strassmann said.
The research challenges the common belief that nutritional interventions for children should cease at age 2. strassmann said that not all children are reached within the first 1,000 days of life.
What’s next
Strassmann suggests that policies in undernourished settings should consider the importance of reducing undernutrition throughout childhood.Weight gain after age 2 can support growth and lead to taller adults without increasing the risk of obesity or hypertension.
