A study by the Universities of Sydney in collaboration with Edinburgh indicates that the daughters who are born first may have a high tendency to be overweight.
The study published in the Journal of Epidemiology & Community Health older sisters
have a 40% probability of suffering from obesity compared to their younger sisters.
The researchers carried out a study of both the conditions of upbringing and the feeding of the girls
.
Overweight in daughters born first.

First-born daughters and overweight
Both the University of Sydney and Edinburgh conducted the study on 13,000 pairs of sisters.
All of them were evaluated and
the preliminary result is that the older ones presented greater probabilities of being overweight in their adulthood.
In total, 29% were overweight and 40% had a tendency to be obese.
The reason for these results would be, according to the researchers, that
the firstborn daughter when they were in her mother's womb had a lower blood supply.
Childhood obesity is an increasingly widespread problem.
Despite this condition, this is not a rule and a lot has to do with the lifestyle you lead,
exercise, and eating a healthy diet before and during pregnancy.
Causes of childhood overweight
Other aspects that older sisters have is that, according to researchers from the University of Edinburgh and the University of Sydney, they would also
have a higher IQ than their brothers.
To reach this conclusion,
they analyzed 5,000 children in the United States, from birth to 14 years of age
.
During that period they had to develop different reading, comprehension, and writing tests, among others.
The results indicated that the first children had better results than their siblings,
from the age of 1 year and they attribute it to the work that the parents do when they are only dedicated to a baby
, once the following children arrive, the mental stimulation is already It is not the same as with the first.
Exercise to combat childhood obesity.
Tips from the University of Sydney to avoid childhood obesity
Focusing solely on immediate solutions, such as diet and exercise programs, will not stem the surge in childhood obesity, the researchers say.
A study from the Charles Perkins Center at the University of Sydney concludes that
children whose parents did not finish high school and who live in a socially disadvantaged situation are more likely to be overweight
or obese in middle adolescence.
High school completion is a strong indicator of socioeconomic status.
These factors were "on-ramps" going down to influence parental body mass index (BMI), which in turn
has immediate lifestyle (diet, sedentary time) implications for the risk of a child child develop obesity.
Professor Louise Baur, a pediatrician at the University of Sydney, says the research explains why most current public health policies to prevent childhood obesity have had limited success.
"We tend to ignore the root causes of childhood obesity, including
social disadvantage, and of course it's not something that parents or children choose for themselves
," said Professor Baur, a co-author from the Charles Perkins Center. of the University.
