The present study examined the differences in the food bank users' perceptions related to calcium nutrition across sex and employment status using a cross-sectional, prospective design at a large food bank in Canada. A total of 197 individuals participated for a response rate of 97%. A structured survey was developed and pilot tested before it was administered. Gender and employment status were the independent variables and calcium nutrition perceptions was the primary dependent variable. Chi-square analyses were conducted. Over 75% of participants perceived calcium to be important, but 47% believed they have insufficient intakes and over 15% admitted to being uncertain of their actual calcium needs. Food costs and not knowing food sources of calcium were indicated as the main determinant for choosing calcium rich foods. While the men surveyed were more likely to be "unsure of sources" of calcium, women were more concerned about the cost of calcium rich foods. Based on the results, it was recommended that nutrition education initiatives should inform food bank users of their calcium needs and economical ways to obtain an adequate calcium intake.
