Study Finds Girls Starting Periods Earlier and Less Regularly
A study by Apple and Harvard reveals that people in the US are starting their menstrual cycles earlier and experiencing more irregularities, which are linked to poor health outcomes such as cardiovascular diseases, cancers, and fertility issues. The mean age of first periods has decreased, and the time to regularity has increased, with childhood obesity and environmental factors like endocrine-disrupting chemicals being potential contributors. The study highlights the need for more awareness and further research.
