Research Critique of “Adherence to Walking or Stretching, and Risk of Preeclampsia in Sedentary Pregnant Women” Introduction
This paper is to critique a study of adherence to walking or stretching during pregnancy in high risk women who were sedentary and had previously experienced preeclampsia. The introduction of this article does give a sense of the importance of the problem area. This four-year study investigates the effects of walking or stretching on the incidence of preeclampsia and reports on adherence to the intervention and on the secondary outcomes of changes in resting heart rate (HR), resting blood pressure and weight gain. Statement of the Problem

The purpose of the study was to compare a walking exercise to a stretching exercise program during pregnancy in high-risk women who were sedentary and had previous history of preeclampsia. The problem was clearly stated and was a feasible researchable problem. The problem had significance for nursing and for the medical profession and might improve practice and education. While the researcher does a good job of stating why the problem is important, it could have been helpful for him to list numbers of people who are affected by preeclampsia and complications of the disease itself.

The research questions were clear by much inquiry. The research questions were: (a) Will previously sedentary pregnant women adhere to an exercise program for 40 minutes a day 5 times a week in the latter half of pregnancy? (b) Is there a difference in adherence to a walking program or a stretching exercise program? (c) How does adherence to walking or stretching change with the advance of pregnancy? and (d) Which exercise is more effective in reducing the risk of preeclampsia? (Yeo 2009).

The title appropriately indicates the target population sampled which are sedentary pregnant women, as well as the key dependent variable hypothesized to be favorably affected by the intervention which is walking or stretching exercise program. The type of research design is a randomized clinical trial and is clearly stated in this report. The abstract is well structured per the journal principles and is complete in presenting the key points of each section of the article. Review of Literature

The literature review that was done by the author was fully cited and pertinent to the research problem. The researcher explains why the research is important and was logically organized. The review concludes lengthy summary of relevant literature and its implications for the research problem under study. The researcher critically reviewed the literature and point out the limitations of the previous studies. The references used were effective in presenting the case for this study. The reference list itself was long with all articles dated. Theoretical Conceptual Framework

There was no theoretical or conceptual frameworks in this study, but could be derived from health promotion model. It is better to have it to support the findings. Hypothesis
The researcher does not state the hypothesis in this study. Predictable hypothesis based on research questions may be “Sedentary pregnant women will adhere to an exercise program for 40 minutes a day 5 times a week in the latter half of pregnancy” or “There is no difference in adherence to a walking program or a stretching exercise program” Methodology

The study was a randomized clinical trial that involved nine clinics in two health care systems in a Midwestern state and an exercise laboratory at a school of nursing. The study was conducted between November 2001 and July 2006. The design was appropriate for the research questions and covered an ample period with a long enough follow-up period. The...
