MIREC-ENDO

What is MIREC-ENDO?

MIREC-ENDO (short for endocrine) focuses on the onset and progression of puberty, metabolic function and growth.

What is Important About this Study?

Many people believe that puberty is beginning earlier and earlier, especially in girls. Unfortunately, the reason for this trend remains unclear. Some suspect that diet and body weight are factors, while others believe environmental chemicals may play a role.

We also want to learn about the factors that may affect body weight and metabolism for both mothers and their children. Some studies suggest a possible link between environmental chemicals and the likelihood of being overweight. We hope to shed some light on this question as well.

Because of the vast amount of data collected in the critical periods of infant and child development, MIREC is uniquely suited to be able to study factors affecting early or delayed puberty, growth and metabolic health. Metabolic health has been defined as ideal levels of blood sugar, triglycerides, high-density lipoprotein (HDL) cholesterol, blood pressure, and waist circumference, without using medication.


A better understanding of the timing of puberty is important as the age at which a child begins puberty can impact their physical and mental health later in life.
