Aim
We previously reported that female babies born small developed cardiovascular risks in middle age. The present study was conducted using the same cohort to examine the relationship between physique at 6 years and the metabolic disease risk in middle age.
Methods
Data collected from 721 women aged 41–69 years who underwent a medical examination at a single institution between 2007 and 2008 were retrospectively examined. We collected data from medical examinations and a questionnaire on physique (thin, normal, and fat) at 6 years. The relationship between birthweight and physique at 6 years was investigated.
Results
Among females who were born small (< 2500 g), 80%, 16%, and 4% became thin, normal, or fat, respectively, by 6 years. Physique at 6 years had a negative relationship with future triglyceride, fasting glucose, HbA1C, insulin, and homeostasis model assessment of insulin resistance (HOMA‐IR) levels and a positive relationship with high‐density lipoprotein cholesterol levels.
Conclusion
Although our findings may be specific to the study population, physique at 6 years had a negative relationship with the metabolic disease risk in middle‐aged Japanese women. Insulin and MOMA‐IR levels negatively correlated with physique at 6 years, and development from low birthweight infants to childhood obesity was rare in this cohort.
