Type A behavior in middle-aged men correlated with smaller meal sizes and increased meal frequency. Higher Type A scores were linked to more sugar and less starch/polyunsaturated fat intake relative to energy. Diet does not explain Type A

Area of Science:

  • Cardiology
  • Nutritional Science
  • Behavioral Medicine

Background:

  • Type A behavior pattern is a known risk factor for ischemic heart disease.
  • Dietary habits are also implicated in cardiovascular health.
  • Understanding the interplay between behavior and diet is crucial for public health.

Purpose of the Study:

  • To investigate the relationship between Type A behavior and eating patterns.
  • To examine the association between Type A behavior and nutrient intake.
  • To determine if dietary factors mediate the link between Type A behavior and ischemic heart disease.

Main Methods:

  • Utilized data from 532 employed men aged 45-59 from the Caerphilly study.
  • Assessed eating patterns and nutrient intake using 7-day weighed dietary records.

  • Employed multiple regression analysis controlling for age, height, social class, and smoking.

    • Main Results:

    • Increased Type A scores correlated with reduced meal size (9%) and increased meal frequency (6%).
    • Higher Type A scores showed trends for increased sugar and decreased starch and polyunsaturated fat intake as a percentage of energy.
    • Significant associations remained for meal size, dietary fiber per MJ, and sugar percentage of energy after controlling for covariates.

    Conclusions:

    • Dietary patterns associated with Type A behavior do not appear to explain the increased risk of ischemic heart disease.
    • The study suggests that the link between Type A behavior and heart disease is unlikely mediated by the investigated dietary factors.
