The eldest daughters would have a high probability of being overweight according to the University of Sydney

A study by the University of Sydney in collaboration with Edinburgh indicates that daughters who are born first can have a high tendency to be overweight.

The study published in the Journal of Epidemiology & Community Health the older sistersWomen are 40% more likely to be obese than their younger sisters.

The researchers conducted a study on both education conditions and nutrition of girls. ​

Firstborn and overweight

Both the Universities of Sydney and Edinburgh conducted the study of 13,000 pairs of sisters. All of them have been evaluated and the preliminary result is that older people were more likely to be overweight in adulthood.

Overall, 29% were overweight and 40% were prone to obesity.

The reason for these results would be, according to the researchers, that the eldest daughter when they were in her mother’s womb had less blood supply.

Despite this condition, this is not a rule and a lot has to do with the lifestyle you lead, exercise and eat a healthy diet before and during pregnancy.

Causes of childhood overweight

Another aspect that older sisters have is that, according to researchers at the University of Edinburgh and the University of Sydney, they too They would have a higher IQ than their siblings.

To reach this conclusion, tested 5,000 children in the United States, from birth to age 14. During that time they had to develop different reading comprehension and writing tests, among others.

The results indicated that the first children performed better than their siblings, from the age of 1 and attribute it to the work parents do when they are dedicated only to a childonce the next children arrive, the mental stimulation is not the same as the first.

University of Sydney tips for avoiding childhood obesity

Focusing only on quick fixes, such as diet and exercise programs, won’t stem the rise in childhood obesity, say the researchers.

This was stated by a study by the Charles Perkins Center of the University of Sydney children whose parents did not finish high school and who live in a socially disadvantaged situation are more likely to be overweight or obesity in middle adolescence. High school completion is a strong indicator of socioeconomic status.

These factors were “on-ramps” that go down to influence the parents’ body mass index (BMI), which in turn has immediate repercussions on lifestyle (diet, sedentary time) of the risk that a child develops obesity.

University of Sydney pediatrician Professor Louise Baur 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 disadvantages and, of course, not something parents or children choose for themselvessaid Professor Baur, co-author of the university’s Charles Perkins Center.
