Scientists from New Zealand found that children who emerged from their parents at the first light, the more prone they have diabetes and hypertension. The scientists also noted that the first-born or only children are more developed physically, and in addition, they are slimmer and higher than their brothers and sisters.
In the study took part 85 children, age at the time of the study was 4-11 years. Scientists took their blood for biochemical analysis, measured weight and height, and also conducted an analysis of hormonal and lipid profile. After processing the received data, the researchers found that first-borns are more sensitive to insulin, and they have higher blood pressure.
Experts believe that the difference in metabolic processes in younger and older children are associated with different processes in the mother's womb, when the amount of fruit substances grows during each subsequent pregnancy.
