Long-term Iron Absorption and Loss in Women
Long-term Iron Absorption and Loss in Overweight/Obese Thai Middle-aged Women
Forrás: ClinicalTrials.gov · Utoljára frissítve: 2026. okt. 2.
Rövid összefoglaló (regiszter, angolul)
Obese people typically have chronic low-grade inflammation. Based on short-term studies, this inflammation could affect the absorption, utilization, storage, and mobilization of iron, and individuals with inflammation might develop iron deficiency (ID) and anemia when inadequacy of iron intake is presented. The double burden of malnutrition is nowadays emerging as a major public health concern in many countries, including Thailand. Understanding the association of chronic inflammation among people with overweight or obesity (OW/OB) with long-term iron absorption and loss is important for developing appropriate policies and programs to promote iron balance and, consequently, optimal iron status and health outcomes. Since previous reports among Thai women showed a high prevalence of OW/OB and anemia, this study will be conducted to determine the long-term iron absorption and loss among OW/OB free-living women using the iron isotope dilution method.
