简要总结
The Offspring Born to Mothers with Polycystic Ovary Syndrome in Guangzhou Cohort study (PCOS-BIG) was established to investigate the short- and long-term effects of intrauterine exposure to maternal PCOS on the health of offspring in Guangzhou, China. Data are collected regarding maternal PCOS subtypes, nursing, diet and education as well as health outcomes in their later life. Biological samples including blood and tissue samples are also collected from participants.
详细描述
According to preliminary survey, the prevalence of polycystic ovary syndrome (PCOS) among Chinese women reached 7.5%. Hyperandrogenism and insulin resistance were considered as the main pathogenesis of PCOS. As reported, the secretion of androgen is higher among women with PCOS than the healthy reference population throughout their fertile lives. Worth of concern, offspring of PCOS patients presented with glucolipid metabolism disorders as early as during their childhood, while whose pathogenesis remains unclear. Prenatal exposure of rhesus monkey in pregnant to androgens produces glucolipid metabolic alterations in offspring resembling those in PCOS, suggesting that the exposure of the fetus to hyperandrogenism during gestation could affect the glucolipid metabolism of PCOS offspring. Growing evidence shows that different exposures during pregnancy will affect the DNA methylation of offspring and disturb their endocrine and metabolism. A birth cohort would provide an opportunity to examine the short- and long-term effects of PCOS exposure, such as hyperandrogenism, on health consequences of the offspring.
