Strengths And Limitations Of Microbiome

Discussion

The research methods in the studies reviewed improved in sophistication and clarity over time from 2011 to 2016. Three of the studies determined that antibiotics resulted in a risk for increased BMI in boys but not in girls (Ajslev et al., 2011; Azad et al., 2014; Murphy, et al., 2014). In general, repeated exposures to antibiotics (Saari et al., 2015; Schwartz et al., 2016; Scott et al., 2016) or broad-spectrum antibiotics (Bailey et al., 2014), in particular macrolides (Saari et al., 2015), were found to be associated with an increase in BMI.

The human microbiome is diverse, complex, and highly individual. Among many functions, gut microbiota are involved in carbohydrate and lipid metabolism (Munyaka et al., 2014; Principi & Esposito, 2016) and substantial research is ongoing in this area (Matamoros et al., 2013). It is reasonable to consider frequent antibiotic exposure in children a possible contributor to obesity, among many other …show more content…
on reversible, persistent, and progressive effects of antibiotics is worthy of replication in other geographic locations with diverse racial and ethnic populations. The three studies in the U.S. have been done in the Mid-Atlantic States (PA, NJ, DE) and sampled only a small number of Hispanics. The prevalence of obesity among Hispanic children in the U.S. is 22.4%, much higher than the overall rate of 16.9% (CDC, 2015a). Hispanics view antibiotics differently than non-Hispanics. For example, Hispanics are more likely than non-Hispanics to believe that antibiotics will help them recover from a cold (48% compared with 25%) (CDC, 2015c). It would be worthwhile to examine what role antibiotics may have in overweight and obesity of Hispanic children. Collection of continuous prescription data during a child’s life would be desirable, but this may be difficult in the absence of a national health care system. Reducing the prevalence of childhood overweight and obesity, and related racial/ethnic health disparities, depends on identification of modifiable risk factors (Bailey et al., 2014; Woo Baidal et al.,

    The study consisted of 36 male adults, with 18 of them having the diabetes. The results showed that the men with type 2 diabetes are associated with compositional changes in intestinal microbiota. When combining microbiota with metabolic diseases (obesity), the glucose level tolerance should be considered. This will broaden more ways to maintain metabolic diseases by modifying the gut microbiota (Larsen,…

    In 1990, obese adults represented less than 15 percent of the U.S. Population but by 2010, the obesity crisis had hit an unprecedented high. Thirty-six “states had obesity rates of 25 percent or higher, and 12 of those had obesity rates of 30 percent or higher” (Centers for Disease Control & Prevention, 2015, para. 1). Today, obesity has fast become a national health crisis, a crisis of vacated immunity when considering approximately two out of three adults are either overweight or obese. Although African Americans have the highest-age-adjusted rates of obesity for reasons to follow, this paper will focus on obesity and its impact on the Hispanic population. Hispanic Population Statistics Currently, national data suggest 78.6 percent of Hispanic males are either overweight or obese, followed by Hispanic females at 77.2 percent.…

    The USDA has been involved in actively promoting good nutrition to the public for more than one hundred years. It was in 1894 that the USDA developed and promoted food guides as a resource to help the American population learn about good nutrition and have the knowledge to choose a diet that was considered healthy for those times. The first USDA food guide consisting of the identification of food groups was developed in 1916. As time went on, the structure for food guides was focused on and evolved around the current needs of the population. These included notions on how to select foods with economics in mind especially during the Great Depression.…

    Although the term health disparities seem to represent a widely understood concept, its definition and exact meaning has caused much controversy. This is due to the fact that the most accepted definition of health disparities focuses on the differences that negatively and systematically affect those groups that are less advantaged and that not all differences in health status are considered to be disparities. Historically, in the United States, racial and ethnic disparities have been the primary point of discussion (Dehlendorf, 2010). The objective of this paper is to shed light onto the various types of disparities that affect Americans, specifically the minority populations and the economic cost. Heart disease is the number one cause of death…

    United States of American has been ranked as one of the most advanced countries in the world, bit one in three American children live in poverty with lack of adult care. In a low-income family, parents’ educational level is linked to low earnings. They usually have very limited food budget and choice on the grocery list. High dietary food then becomes the primary choice for children in poverty.

    Such studies can be used to an advantage when trying to predict if a specific environmental change could possibly affect stable gut microbiota, causing the microbes to become unstable, disrupting a previously beneficial symbiosis. I found this reading to be an extremely useful conceptual tool when trying to understand how microbe symbiosis and the environment can affect each other. Very few studies have targeted this factor in the past, and I believe it is important to identify with this factor of symbiosis in order to fully understand how the environment and the species within that habitat directly and indirectly affect one…

    Childhood obesity has been considered as an epidemic disease according to the CDC and there are numerous factors that contribute to the increase in rates. Some studies claimed that the prevalence of childhood obesity is common among children who belong in the low socioeconomic household. According to Ogden and colleagues, between the years 2011-2012, there were 16.9% of the youth who were included in the assessment were obese in the United States, and the rate has been consistent since 2009-2010.

    Lastly, human creations such as antibiotics and Frankenstein’s monster can have long term and sometimes permanent unintended consequences. When the monster escapes from his creator’s workspace in Frankenstein, he ends up creating horrific and permanent damage on the world by committing numerous murders. At the end of the novel, the monster himself even reflects on the evils that he has inflicted upon the world. He remorsefully states that he has “‘murdered the lovely and the helpless[,] . . . strangled the innocent as they slept, and grasped to death his throat who never injured [him] or any other living thing” (Shelley 202).…

    Obesity in America becomes a more relevant issue as time progresses and people develop terrible habits. Yvette C. Terrie, a writer from U.S. News Health states, “In the past two decades in the United States, there 's been an alarming increase in obesity rates among all age groups, even children. It 's estimated that more than one-third of adults and 17 percent of children and adolescents are obese.” These numbers are alarming because of the massive amounts of health problems that obesity causes such as diabetes, Coronary artery disease, and cancer (Terrie). Although it may not seem like it, some obese people have diseases or health complications that result in excessive overweight.…
