Upstate New York Infant Development Screening Program (Update KIDS)
Phase 1: Growth and Development
This Study aimed to determine whether infertility treatments, such as ovulation-stimulating medications and various assisted reproductive technologies (ART), adversely affect the growth, motor, and social development of children from birth through age three years, or if these technologies are associated with differences in the timing or rates of infant and child development, including motor and social development, the development of major and, especially, minor neuro-developmental impairments, and with physical growth patterns. Secondarily, but equally important, the Study also aimed to determine to test the American Academy of Pediatrics (AAP) developmental surveillance and screening algorithm. The Study aimed to provide information to the State of New York Department of Health that will allow it to more effectively plan and implement the New York State Early Intervention Program (EIP) and, by extension, to inform other States' programs nationally.
The Upstate KIDS Study, which represents a collaborative effort among the DIPHR Epidemiology and Biostatistics & Bioinformatics Branches, the New York State Department of Health, and the University at Albany School of Public Health, implemented a matched-exposure cohort design recruiting infants who were born between 2008 to 2010 in New York State (exclusive of New York City). Using vital records data, all children conceived by infertility treatment and all twins were recruited. In total, ~1,300 families whose child(ren) were conceived with infertility treatment (exposed) and ~3,700 families whose child(ren) were not conceived with any infertility treatment (unexposed) were recruited. A separate cohort of all higher-order multiples (triplets, quadruplets) were also recruited. Parents completed the infant questionnaires along with the Ages & Stages Questionnaire© developmental screen at 4, 8, 12, 18, 24, 30, 36 months of chronologic or gestation-corrected age and the Modified Checklist for Autism in Toddlers at 18 and 24 months. Children who did not pass the screen were referred to the NYS Early Intervention Program (EIP). In a subgroup, residual newborn blood spot samples (punches) from the Guthrie cards were retrieved by the NYS Newborn Screening Program for analysis of inflammatory and immune markers that may indicate an intrauterine infection and be predictive of later disease or delays in development. The Study also conducted linkages to the Society for Assisted Reproductive Technology Clinic Outcome Reporting System (SART CORS), NYS Congenital Malformations Registry, Cancer Registry, Newborn Screening Program, and the EIP, among others.
Phase 2: Cardio-metabolic health
Recent studies have drawn attention to concern that infertility treatment exposure may also increase cardio-metabolic risk. Low birth weight and preterm birth are tied to cardiovascular disease risk and mortality later in adult life. Both adverse birth outcomes are increased among singletons and twins conceived by IVF and among children conceived techniques apart from ART compared to children conceived naturally. These adverse birth outcomes of children conceived by infertility treatment may serve as an indicator of increased cardio-metabolic risk later in life. Increased risk among those having good birth outcomes, however, cannot be ruled out. The timing of puberty is also of interest, as some pubertal markers appear altered after IVF conception and early adrenarche may confer additional cardio-metabolic risks. Few studies have followed children conceived by non-ART treatment. As such, the cardio-metabolic status of children exposed to infertility treatment inclusive of ART remains unclear.
The Upstate KIDS Follow-Up Study, which remains a collaborative effort among the Epidemiology and Biostatistics & Bioinformatics Branches at NICHD and the University at Albany School of Public Health, will continue the follow-up of approximately 3200 children from the original cohort through age 8 years primarily by annual questionnaires. A subgroup will be invited to participate in a home visit program where measurements of cardio-metabolic risk along with biospecimens will be collected from mothers and their children. Lastly, all children will be asked to donate a saliva sample by mail when they reach age 8 years.
