Diet diversity and nutrient intakes in patients with Prinzmetal angina


Objective: Dietary diversity has been recommended to be effective in achieving an adequate nutrient intake. Few studies have investigated dietary diversity and nutrient intake in Prinzmetal angina patients. This case-control study aimed to assess the association between dietary diversity and Prinzmetal angina incidence.
Method: Energy and nutrient intakes were measured using three day 24-h recall. Dietary diversity was measured by summing the number of food groups consumed over 12 weeks. Independent-samples t test was used to compare quantitative variables between the groups.
Results: The mean score for Prinzmetal angina patients was 3 ± 0.025 groups/day, for controls was 4.5 ± 0.053 groups/day. There was a significant difference in diet diversity score between the groups (p = 0.01). There were significant differences in macro and micronutrient intakes between the groups with the exception of copper (p < 0.05). Intake of vitamin B12 in cases was 0.8 ± 0.02 μg/day and in controls was 1.5 ± 0.01 μg/day. Iron and zinc intakes in cases were lower than in controls.
Conclusion: Increasing dietary diversity in patients with Prinzmetal angina can be an important approach to declining the clinical symptoms of Prinzmetal angina.
