- Abstract
Introduction: Based on data from Cycle 2 (2009-2011) of the Canadian Health Measures Survey (CHMS), 97% of Canadians 3-79 years had sufficient hemoglobin concentrations (Hb). Serum ferritin (SF) sufficiency for women aged 12-19 years and 20-49 years were lower at 87% and 91%, respectively. In view of changing dietary patterns, it is important to monitor iron status on an ongoing basis. Objectives: To determine iron sufficiency of Canadians (3-79 years) from CHMS Cycle 3 (2012-2013) and its relationship with selected demographic and dietary variables. Methods: CHMS Cycle 3 data from 5760 participants, representing 96% of Canadians, were analyzed using SPSS. CHMS survey weights were applied; data for pregnant women and individuals with abnormally high laboratory values were excluded. World Health Organization reference values for age and sex were used to estimate iron sufficiency based on Hb, SF, and other markers. Results: 95% of Canadians had Hb at or above age group and sex references. Of the 5% who were anemic, 61% had SF greater than reference values. The lowest Hb sufficiency (89%) was for females aged 20-64 years. Overall, 94% of Canadians had sufficient SF with 78% and 85% for women 12-19 years and 20-49 years, respectively. Hb and SF were significantly lower for those with low incomes and for those who reported good/fair/poor versus excellent/very good health. For women, Hb and SF were significantly higher for those consuming red meat, pasta and green leafy salads 1-3 times/week compared to those consuming these foods 4 times/week. Discussion: The proportion of young women (12-19 years) with sufficient SF dropped from 87% in Cycle 2 to 78% in Cycle 3. This is of concern given that it is crucial that women of child-bearing age have sufficient iron stores for pregnancy. Relevance: These results suggest that consumption of ironrich foods should be emphasized, particularly for women of child-bearing age.
