Scientists trace teen puberty back to babyhood

This study aims to understand if factors during infancy—like hormones, feeding, or environmental exposures—influence a child's growth and the timing of puberty in their teenage years. Researchers are following up with children and their parents from a previous infant study, collecting information through home questionnaires, body measurements, and urine samples. The goal is to gather knowledge about what might be causing puberty to start earlier, which is linked to various health concerns later in life.
