Yes—anemia rose from 8.0% to 14.2% among U.S. women ages 20–45 who were not pregnant, from 1999–2000 to 2021–2023. The study used national health survey data from 8,200 women. Researchers compared blood test results across surveys spanning 1999 through 2023. These were snapshots of different women, not the same women followed over time. Two blood markers helped separate low iron from anemia. The study defined low iron as Ferritin below 15 micrograms per liter. It defined anemia as Hemoglobin below 12 grams per deciliter. Hemoglobin is the protein that carries oxygen in blood. Women below both cutoffs were counted as having anemia with low iron. Anemia with low iron more than doubled, rising from 4.3% to 9.1%. Low iron alone followed a different pattern. Its rate went from 17.9% to 18.8%, without a clear change. So, low iron remained common while anemia became more common. Across all survey years combined, 17.3% had low iron. That represented an estimated 5.70 million women nationwide. For this community, the key distinction is that these results aren't interchangeable. A Ferritin result and a Hemoglobin result answer different questions. The study counted women with low iron even without anemia. It did not establish why anemia rates rose or test a treatment. When comparing bloodwork on BioSocial, sharing both values could add useful context. Dates and units can also make comparisons clearer. Community notes can help show how individual patterns differ from national trends. These population numbers don't show how any one person's results changed. What patterns have you noticed in your Ferritin and Hemoglobin results over time?
