| Research Abstract |
We examined the relationship between body mass index (BMI) during the period of adiposity rebound (AR), in which BMI increases in babyhood and begins to increase again after temporal decrease in childhood and at the age of 12 years, and the risk factors of arterial sclerosis, i.e., serum lipid level and blood pressure, in a birth cohort. As a result, it was demonstrated that: 1) abnormal findings, i.e., high BMI at 12 years of age, dyslipidemia, and high blood pressure tended to be observed in children with early AR, especially those aged 4 years or younger, 2) since no correlation was confirmed between the increase in body weight in babyhood and the period of AR, baby obesity doesnot cause future obesity, 3) the incidence of obesity at 12 years of age was lower in children with maternal feeding than in those with artificial feeding, 4) the living environment and habit, which may affect early AR are characteristic. It was revealed that future obesity and metabolic syndrome could be prevented by early intervention of the living habit inchildhood with a focus on the period of AR.
