OBJECTIVE: Identified Thai adults' knowledge and attitudes towards calcium and determined factors predicting calcium consumption. MATERIAL AND METHOD: One thousand four hundred seventy five Thai adults, aged > or = 20 years old were interviewed, using a semi-structured questionnaire. Knowledge about role of calcium and good sources of calcium was measured using 17 questions. Attitudes towards calcium were measured with 10 opinion statements, using 7-point Likert scale (1 = strongly disagree to 7 = strongly agree). Calcium consumption, based on a 24-hour recall, was assessed using food frequency checklists and open-ended questions. RESULTS: The median score for knowledge was 15 (IQR: 12, 16; total possible score: 17). The overall median of attitudinal score was 5.6 (IQR: 4.9, 6.1; cronbach's alpha = 0.80). Approximately 10.9% consumed adequate amounts of calcium (800 mg/day). CONCLUSION: Factors significantly determining the likelihood an adequate intake of calcium were age < 35 years, support from peers and taking calcium-supplements.
