Anemia in Older Adults

A cross-sectional study with 829 older Mexican adults were recruited from July to September 2015, from four localities in the southern region of México. Older adults were interviewed at their homes and a fasting blood sample was obtained for analysis of micronutrient status (iron deficiency, vitamin B12 deficiency, folate deficiency, vitamin A deficiency and biomarkers of inflammation). The aim of the study was to identify the main causes of anemia in older adults with higher rates of anemia according to the recent data of the Mexican National Health and Nutrition Survey.

About this study

A survey with cross-sectional design was applied in 829 older Mexican adults, recruited during the period July to September 2015, from four localities in the southern region of México: including Champotón, Campeche, Mérida, and Valladolid. Older adults were interviewed at their homes to collect nutrition, health, cognitive and dietary information. Anthropometric measures and functionallity tests were also collected. A finger prick capillary blood sample was collected to measure hemoblobin in situ using HemoCue. Anemia was defined according to WHO criteria. A fasting venous blood sample was collected in 803 older adults. Serum was separated and frozen at -20°C to measure ferritin, retinol, vitamin B12, folate, iron, soluble transferrin receptor, C-reactive protein, interleukin 6, alpha glycoprotein 1, hepcidin, erythropoietin in the laboratory of nutrition of the National Institute of Public Health.

The study protocol was approved by Research, Biosecurity and Ethics Committees of the National Institute of Public Health. Participants received a detailed explanation of the study procedures and signed an informed consent form prior to data collection.
