Sisters are not always alike, Mother Nature has her moods. There can also be striking differences in size and weight. A study by the University of Auckland’s Liggins Institute and a group of Swedish scientists has now shown that the first-born sisters are often the ones who weigh more.

For the study, 13 400 pairs of female siblings were studied for more than 18 years. The result: firstborn babies suffer 30 percent more from overweight than their smaller sisters. In addition, they are 40 percent more prone to obesity than their second siblings. However, according to the study, firstborns are generally slightly larger than their siblings. Unfortunately, the scientists cannot yet explain why this is so.

At this point, older sisters are encouraged to make a conciliatory study that says: People with sisters are more optimistic and more balanced.nOther exciting results from sibling research make firstborns score points. According to a study, the first child is a little more responsible, conscientious and dominant and suffers less from anxiety than its siblings.
