Correlation and Causation
Correlation alone does not mean causation, though the news cannot resist to use correlation to mean more than it does. Today we analyze three articles for proper use of correlation and causation. The attempted correlation, and causation statements made were including sleep with weight change, church goers and obesity, and having kids and being unhealthy.
Discussion
In the world of news reporting correlation often times gets reported as causation. This is not the case, since correlation inherently by definition requires further testing to show causality. These articles all refer to a different variable that shows correlation with weight gain or loss. It is our job to question all statistical statements made by our news. The articles we will study are "The Link Between Sleep and Weight", "Why Going to Church Can Make You Fat", and "Why Having Kids Is Bad for Your Health".
The Link Between Sleep and Weight
In the article "The Link Between Sleep and Weight" they use a few different study findings to support their claim of causation. The first involved a group of 40-60 year old women. These women had their weight and sleeping patterns tracked. This first study found that most of the women that had bad sleeping patterns were significantly more likely to have a major weight gain of equal to or more than 11lbs (McCoy, 2010). The second study involved observing the exercise and eating habits of a group of young men after sleeping for eight hours and four hours on two consecutive nights. The researchers found that the the men ate 560 calories more during the day after sleep deprivation compared with their well rested counterparts. The researchers discussed in this article claim that children are further at ris...

Desai, William C. Miller, Betty Staples and Terrill Bravender. I believed that this was a credible source because all of the authors have a medical degree. This article provided similar data saying that the percentage of people ages 12 to 19 who were overweight or obese rapidly increased from 5% to 17% between 1976 and 2002 (Desai 109). From this document I learned that college years are known to influence the forms of our adult behaviors including diet, physical activity, and other habits. Being a college student, I knew that college was going to change my work ethic and ability to do achieve new responsibilities but I did not know that it could actually greatly affect our weight. In the source it states that results from “both the National Longitudinal Study of Adolescent Health and the National Health and Nutrition Examination Survey" show that the transition to adulthood, a high number of people become obese and remain obese (Desai 109). One way I thought of this transformation was the freshman fifteen. The source was able to identify patterns of obesity but they still have not fully discovered examples of obese behaviors. However, the authors of this paper were able to perform a study to at least suggest some examples of behaviors related to obesity. They examined data collected from an electronic survey

In the recent decades, obesity has grown into a major health issue in the United States within young people. With 31 percent of the United States of children being obese, the United States has become the country with the highest rate of obesity in the world. Obesity is not only found among adults, but it is also now found mainly among children and teenagers. The childhood is a very important period for the initiation of obesity especially in this time. Eating practices that children are taught or learn during childhood affects a person later in their life whether they know or not. Multiple studies have confirmed that childhood obesity in the U.S has been on a rise for years. One out of three children in the U.S are obese, most of them face a higher risk of having medical, social and academic problems. Childhood obesity also leads to many health problems among young people. Those problems include diabetes, high blood pressure, high cholesterol and many more others. These problems cause a rise in health care costs that their families might have to pay sooner or later. The influence of parents and the media play a big role in causing these problems to happen. Some people believe that a family with an obese child should not raise child protection concerns if obesity is the only cause for concern (Callaghan, 2010). However, doctors should always be mindful of the possible role of abuse or neglect in contributing to obesity. The result of some research that was done on the symptoms of neglect shows a clear correlation between childhood abuse and obesity in childhood. A study of American school children has found that after controlling for socioeconomic status, those who were physically abused were more likely to be obese (Callaghan, 201...
Did you know that 35% of the United States population is considered obese? Also, 66% of the population is considered overweight or more? (Saint Onge 2014) Even more frightening, in 2012 the Center for Disease Control and Prevention reported that more than one third of children and adolescents in America were overweight or obese (CDC 2014). The media sources used investigates the political, scientific, historical, and cultural reasons behind the childhood obesity epidemic in America. Obesity is a rapid growing epidemic in America and these sources present the facts causing this epidemic. As well as how the children of the American society are being wrongly influenced by the media, especially advertisments. (Greenstreet 2008).

sleep in America and its effects on performance. The articles gave different types of results from different kinds of data with different degrees of definiteness. In spite of their differences, both articles showed that lack of sleep is a cause for decreased performance and a detriment to a productive and healthy lifestyle.
Does correlation mean causation? We are reminded on a daily basis that if we do not wear our seatbelt, we will die if we crash. This idea comes from the belief that if one wears a seatbelt they will be saved in the event of a crash. With that, I could say that wearing a seatbelt and surviving a crash are correlated so one must cause the other. However, there have been plenty of instances where people die in a crash while wearing a seatbelt. People tend to confuse correlation with causation because they simply try to justify why a situation happened based on what they think they have knowledge about but also because they do not fully understand causality.
When it comes to the topic of childhood obesity, most of us will readily agree that there are long-term medical affects associated with childhood obesity. The National Institute of Health states that obese children are more likely to become obese adults. Adult obesity is associated with a number of serious health conditions including heart disease, diabetes, and some cancers (National Institute of Health). Where this argument usually ends, however, is on the question of who is to blame. Whereas some are convinced that the government and the food industry are to blame, others maintain that parents are primarily bearing this burden. The people who believe the government and the food industry are to blame are consistently at odds over the issue of who is to blame for the long-term affects from childhood obesity with the people who tend to believe parents are to blame. Medical conditions are becoming more and more frequent, childhood obesity is becoming a growing problem and until recently, the government has not aided in the fight against obesity.
It is said that an obesity epidemic is sweeping the country and that the numbers are astronomical. Approximately 31% of all adults and 15% of children, ages 6-19 are obese. Obesity is also severe in a variety of ethnic groups. For example, 50% of non-Hispanic black women are obese. Many researchers believe that the trend in obesity as a lot to do with cultural, economic, and environmental factors. Simply stated I think it can be attributed to genetics, portion size as well as food available and cost, and laziness.

The CDC states that, “[o]verweight is defined as having excess body weight for a particular height… Obesity is defined as having excess body fat.” (1) Their data shows that “[i]n 2012, more than one third of children and adolescents were overweight or obese.” According to the information they provide, this translates to a more than quadruple increase since 1980. These statistics prove that this pro...
Obesity: Our weight also depends on our sleep duration. Studies show that people who slept for 9-10 hours are more likely exposed to obesity compared to those who slept between 7-8 hours. Even when food intake and exercise were taken into account, this link between sleep and obesity stayed the same.
