Clinical Trial Summary
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.
Description:
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.
