WEDNESDAY, Dec. 20, 2023 (HealthDay News) — Being born after assisted reproductive technology (ART) is not associated with higher body mass index (BMI)\u00a0at age 5 to 8 years, according to a study published online Dec. 19 in\u00a0PLOS Medicine<\/em>.<\/p>\n Kristina Laugesen, M.D., Ph.D., from Aarhus University in Denmark, and colleagues examined associations between different fertility treatments and BMI in children at age 5 to 8 years. The analysis included 327,301 Danish children born between 2007 and 2012 (13,675 born after ART and 7,728 born after ovulation induction with or without intrauterine insemination [OI\/IUI]).<\/p>\n The researchers found that the crude prevalence of obesity was 1.9 percent in children born after ART, 2.0 percent in those born after OI\/IUI, and 2.7 percent in those born after no fertility treatment. Children born after ART and OI\/IUI had the same prevalence of being overweight (11 percent; prevalence odds ratio [POR], 1.00 [95 percent confidence interval (CI), 0.91 to 1.11]; P = 0.95) or obese (1.9 percent; POR, 1.01 [95 percent CI, 0.79 to 1.29]; P = 0.94) in adjusted analyses. A similar pattern was seen when comparing intracytoplasmic sperm injection with conventional in vitro fertilization (overweight: POR, 0.95 [95 percent CI, 0.83 to 1.07]; P = 0.39; obesity: POR, 1.16 [95 percent CI, 0.84 to 1.61]; P = 0.36). After frozen-thawed (2.7 percent) embryo transfer, obesity was more prevalent than after fresh embryo transfer (1.8 percent; POR, 1.54 [95 percent CI, 1.09 to 2.17]; P = 0.01).<\/p>\n “Our overall null results provide reassuring results for couples with infertility seeking help,” the authors write.<\/p>\n
