Study found out older sister weigh more than their younger counterparts and slightly taller.
First-born sisters were found to be slightly taller than the younger oneâ€™s, however more likely to be more overweight. In the study conducted, height, weight, lifestyle and family history being included in the data collected as bases. Reasons for differences between first-born and those born later, still to find out.
Obesity may lead to health problems including diabetes, heart disease, stroke and some cancers issues. Based on the recent studies, first-born sisters are at greater risk of health problems, diabetes and high blood pressure on the list in later life than their siblings. â€śThe steady reduction in family size may be a contributing factor to the observed increase in adult BMI worldwide, not only among men, but also among women, they concluded.
Dr. Wayne Cutfield, senior author of the study and a professor of endocrinology at the University of Auckland in New Zealand stated, â€śThis study backs up the findings of three earlier studies conducted by [the research team] in adult females, adult males and children of both sexesâ€ť. Findings should not be treated as a â€śprediction that they will become obese, diabetic or hypertensiveâ€ť.
â€śWe found that firstborns were nearly 30 per cent more likely to be overweight, and 40 per cent more likely to be obese than their second-born sisters.â€ť, â€śCollectively, these studies show that both men and women who are born first are at greater risk of being overweight or obese.â€ť, â€śThe differences of about 20 to 25 per cent in obesity and insulin sensitivity between firstborns and those born later are not large enough to be a major determining factor. What this information about health risks does is to empower firstborns so they can make positive choices about diet and exercise,â€ť Professor Wayne added on study on first-born sisters to be more overweight than the young one.
Senior Cardiac Nurse at the British Heart Foundation, Maureen Talbot, said: â€śSince sibling rivalry can be a great motivator, brothers or sisters could use it as encouragement to eat as healthily as possible and stay active.â€śBeing overweight or obese can make you more likely to develop cardiovascular disease so itâ€™s important to keep to a healthy weight no matter whether youâ€™re the firstborn or the baby of the family.â€ť data showed that at birth, the firstborn sisters weighed a little less than their second-born sisters, on average IMAGE/ALAMY
