Egg Consumption Essay

There have been numerous debates about whether or not egg consumption is associated with the risk of coronary heart disease (CHD), stroke, or carotid plaque area. Two studies have been conducted to address this issue. The first study used a non-experimental research design (longitudinal (cohort)) to examine the association between egg consumption and risk of CHD and stroke in men and women. The dependent variables in this study were the risk of CHD and stroke. The independent variables were egg consumption and characteristics of the participants (total energy/food intake; smoking; age; alcohol consumption; history of hypertension and diabetes; parental history of myocardial infarction (MI); body mass index (BMI); multivitamin use/vitamin E …show more content…
The researchers used a non-probability sampling method (convenience sample and volunteer). The sample for this study was a total of 37,851 men (aged 40 to 75 years) and 80,082 women (aged 34 to 59 years), free of cardiovascular disease, diabetes, hypercholesterolemia, or cancer. Food-frequency/validated dietary questionnaires were sent to the Health Professionals Follow-up Study (HPFS) participants and the Nurses’ Health Study (NHS) participants. However, the questionnaire was further expanded to include 116 items (in 1984), and it’s comprised of an inclusive diet survey and items on medical history and lifestyle practice. Participants later received follow-up …show more content…
(1999) and Spence et al. (2012), scrambled eggs (inclusive of egg yolks) should be offered on the daily breakfast menu in the cafeterias at New Haven public schools. For instance, the study by Hu et al. (1999) showed no evidence of an overall significant association between egg consumption and risk of CHD or stroke in either men or women. In the same way, the study by Spence et al. (2012) demonstrated that there was no significant correlation between egg yolk consumption and smoking history, but plaque area increased linearly after age 40. In addition, both studies used participants who were between the ages of 40 to 75 years, so it would be difficult to generalize the study to New Haven public school students. There were also threats to both internal and external validity in both studies. Therefore, the results should not be generalized to New Haven public school students. The results can only be generalized to participants in the current experiments. Moreover, the article by Hu et al. (1999) did not compute a correlation coefficient between two sets of similar measurements to test for reliability of the method of measurement. The three methods most commonly used in health education research to calculate reliability are Cronbach’s alpha, Kuder-Richardson (KR) 20 coefficient, and the Spearman-Bowman split-half reliability procedure, and the researchers did not use
