When a child is born, his or her parents hope for the best while also wondering what the world has in store for their little one.
While being a new parent can feel unpredictable, new research suggests a baby’s body mass index (BMI) can help predict obesity later in life.

However, new research from the Cincinnati Children's Hospital Medical Center shines some light on its potential.
The researchers say weight gained during infancy is different than pounds put on later in life.
Their findings were presented today at the national Endocrine Society meeting in Boston.
BMI in Babies
The researchers studied 783 lean and 480 obese participants, including those referred to specialized care at Cincinnati Children’s Hospital Center.
The scientists say they found the weight trajectories of children who were obese by 6 years old were different than those who were at a healthy weight at 4 months old.
The research team then double-checked their findings by studying young children seen by a pediatric clinic in Denver and found their research also applied to this group.
Dr. Allison Smego, the study’s lead author and a fellow in the division of endocrinology at Cincinnati Children's Hospital Center, said BMI above the 85th percentile at 6, 12, and 18 months can accurately predict a child’s risk for early childhood obesity.
"These children have a high lifetime risk for persistent obesity and metabolic disease and should be monitored closely at a very young age," Smego said in a press release.
While this doesn’t automatically mean an obese infant will become an obese adult, it could help identify those who are at a higher risk so early interventions can be implemented.
“Pediatricians can identify high-risk infants with BMI above the 85th percentile and focus additional counseling and education regarding healthy lifestyles toward the families of these children,” Smego said. “Our hope in using this tool is that we can prevent obesity in early childhood.”
About a third of adults and children in the U.S. are overweight or obese, so the healthcare system faces a major hurdle in attempting to deal with the related health risks.
Some of the risks include a shortened lifespan due to metabolic diseases like diabetes, heart disease, and even some types of cancer.
More People Obese Than Underweight
Globally, the number of obese adults has risen dramatically, from 105 million in 1975 to 641 million in 2014, according to a new study in the Lancet.
Examining BMI records, researchers found the world’s population is adding about 3.3 pounds per person every decade. At this rate, a fifth of men and women worldwide will be obese and 6 percent of men and 9 percent of women will be severely obese.
However, poorer countries still have to worry about malnutrition.
That’s something Dr. George Davey Smith, professor at the MRC Integrative Epidemiology Unit, School of Social and Community Medicine in the United Kingdom, calls "a fatter, healthier, but more unequal world.”
"A focus on obesity at the expense of recognition of the substantial remaining burden of undernutrition threatens to divert resources away from disorders that affect the poor to those that are more likely to affect the wealthier in low income countries," Smith wrote in a commentary accompanying the Lancet research.
