Outline of Final Research Achievements

We performed an exploratory and systematic analysis of a birth cohort to determine which period, i.e., babyhood, childhood, or school age, would be the “critical window,” the period of weight increase most closely related to the development of metabolic syndrome, based on adolescent obesity and insulin resistance. As a result, it was suggested that the weight increase in childhood, not in babyhood, would be closely related to future obesity and metabolic syndrome. In addition, it was estimated that children with an increase of body mass index (BMI) from the ages of 1.5 to 3 years would exhibit a greater increase of insulin resistance (HOMA-IR) for BMI increase at the age of 12 years, compared to those with a decrease of BMI, suggesting a high risk of metabolic syndrome. It was suggested that children who exhibited an increase in BMI at the 3-year medical checkup, compared to that at the 1.5-year checkup, should be selected as high-risk children.
