Asthma Research Paper

Introduction

Asthma is a chronic condition of complex relationships between the bronchial tubes, inflammation, obstruction and hyper responsiveness (Deppong et al., 2008). It can be triggered by the environment, weather conditions, strenuous exercise, respiratory infections, and atopy. Asthma has become more and more common in developed countries such as the U.S. and so has obesity, which leads researchers to question whether there is a potential causality. Several research studies have suggested that there is a positive relationship between these two chronic ailments and such information can aid health professionals to better treat these patients. Studies on this subject matter also found that subjects who lost weight displayed improvements in lung function (Davis et al., 2007). With that being said, I propose to investigate the association between obesity and asthma and also determine whether weight loss affects the performance of lungs for asthmatic individuals. I have chosen to incorporate the study conducted by Stenius-Aarniala et al. (2000), which is a randomized controlled study that was conducted in Finland. I chose this study

The control group received the same medical treatment and as much attention as the treatment group (Stenius-Aarniala et al., 2000). This study was conducted as a randomized control study, therefore, that limits the possibility of biases. However, after randomization some of the participants in the control group may have been disappointed for not being in the treatment group, which can influence his/her evaluation of symptoms and health status (Stenius-Aarniala et al., 2000). The main variables in this study are physical activity, diet, and rescue medication, which can consist of confounding factors. However, even with one participant who began smoking and the two participants who found the diet intolerable, there weren’t any significant
