pregnant women during the second trimester (19) (Dubois et al., 2017).Understanding the value of measures undergone by the researchers are of great value to form a reputable study. It is obvious that key variables were indeed operationalized using the chosen methods. Aswell, specific instruments were adequately described in the methods portion of the study, and indeed NURS 328
RESEARCH STUDY: STUDENT CRITIQUE9powerful analytic methods were used in order to ensure the analysis helped control the extraneous variables hence the research and design of the report, excluding the lack of additional data as mentioned earlier are sound. An area of the study however, that clearly missed the mark would be the population and sample methods, which an informed reader would consider being far from being a true depiction of the Canadian population.In 1965 an insightful man, Austin Bradford Hill, an english epidemiologist and statistician who pioneered the randomized clinical trial and demonstrated the relationship between cigarette smoking and lung cancer published a paper entitled “The Environment and Disease: Association or Causation?”, wherehe outlined 9 various viewpoints from which we as researchers should study association before we cry causation (Hill., 1965). These viewpoints mesh perfectly in todays nutritional research studies. Making Hill’s work is of extreme importance to the critiqued study at hand, the quotes to follow by Hill are of powerful value and tools for all researchers to consider when carrying out a study of causation.“Consistency: Has it repeatedly been observed by different persons, in different places, circumstances and times?” (Hill.,1965)The answers in relevance to The Adequacy of nutritional intake from food and supplements in a cohort of pregnant women in Quebec, Canada would be, no, yes and, not sure. Reasons being, the major fault of the cohort study is, of the 1533 participants over 50% belong to a household with an average income well above the median of Quebec, and definitely far above the average household income of Canada as a whole. 94% of the participants have a post secondary education, and 71% were born in Canada. These statistics alone hinder the replicability, the validity, and contributions efforts of the study. These values are not true representations of the diversity of Quebec, these values do not take into consideration the various diets of diverse ethnicities, nor consider the nutritional inadequacy of lower household incomes and various social economic status found in many Canadian households. The sampledpopulation is not a true representation of Canada, and thus will not be of good value of research in clinicalapplication in government regulated facilities. NURS 328
RESEARCH STUDY: STUDENT CRITIQUE10The second point drawn from Austin Hill’s work comes from the same article, “The Environment and Disease: Association or Causation?”, wherein he mentions the idea of temporality,“[4] Temporality : Which is the cart and which is the horse? Does a particular diet lead to disease or
