NUSC 5173: Quantitative Epidemiology I
WEEK 5 Discussion Questions
Discuss how the results might have been affected if the comparison group was: (1) no milk instead of non-fortified milk; (2) Discuss how the results might have been affected if the comparison group was: milk fortified with other nutrients besides those being investigated in the study.
The experimental aim of the Sazawal study was to "to evaluate the efficacy of milk fortified with specific multiple micronutrients (providing additional 7.8 mg zinc, 9.6 mg iron, 4.2 g selenium, 0.27 mg copper, 156 g vitamin A, 40.2 mg vitamin C, 7.5 mg, vitamin E per day (three feeds) x 1 year) on morbidity in children compared with the same milk without fortification” (Sazawal et al., 2007, p.1). Therefore, this study has one independent variable (IV) (fortified milk) and one control variable (unfortified milk) and several dependent variable (days with severe illnesses, incidence and prevalence of diarrhea, acute lower respiratory illness/pneumonia, and morbidity in children). In the Sazawal study (2007), the researchers specifically discuss the outcome on morbidity dependent on the assignment to fortified (intervention) or non-fortified (control) milk (see Table 3, p. 4), which demonstrates multivariate …show more content…
Additionally, in order to adhere to ethical standards, researchers must submit their study plans to the Institutional Review Board (IRB) as they are the U.S. external review committee designed to protect human rights (Polit & Beck,
