If you have siblings, you likely have distinct feelings about your position in the family hierarchy—whether as the esteemed eldest, the cherished youngest, or the often-overlooked middle child. You may have spent years grumbling about how you paved the way for your younger siblings. However, recent research suggests you might want to express some gratitude instead, as having a sibling could be linked to better health outcomes for the firstborn.
A study conducted in the U.S. and published by the American Academy of Pediatrics reveals that children who welcome a sibling before reaching first grade have a lower likelihood of becoming obese. You might wonder: is it due to the older sibling constantly being chased by their playful younger counterpart? Or is it simply a matter of families distributing their food resources among more mouths? Perhaps parents with multiple children are more inclined to take their kids to parks for active playtime at various times throughout the day?
While the study does not delve into the reasons behind this correlation, it indicates that the arrival of a sibling prior to the first child turning six is associated with healthier body mass index (BMI) trajectories. Importantly, it does not claim that only children are destined for obesity, but rather suggests that the dynamics and lifestyle changes that come with a second child may lead to healthier habits. For instance, you might find yourself less concerned when your older child doesn’t finish their meal, as exhaustion takes over while your children zoom around you.
Childhood obesity is influenced by numerous factors, making this study just one piece of a complex puzzle. Previous research has linked obesity to maternal health, pregnancy weight gain, family history, and even the influence of deli meats or C-section births. It seems like everything is on the table, including the cultural phenomenon of popular children’s shows like Caillou.
Despite its intriguing findings, this study is unlikely to sway those undecided about expanding their family. After all, it lacks the romance of suggesting that having another child might lead to a healthier firstborn. When considering whether to have another child, there are many layers to unpack—financial implications, work-life balance, educational needs, and housing logistics. The idea of having a second child to potentially lower the BMI of your already wonderful firstborn is unlikely to top your list of reasons.
Moreover, just because siblings may promote active lifestyles does not automatically mean parents will also enjoy better health. If your strategy for surviving parenting involves pairing fine wines with crunchy snacks, I fully support your choices. Now that’s the kind of study worth celebrating!
