Are you seriously going to say to someone who is metabolically fit but fat, who eats well, who exercises regularly, that they still have to lose weight? You are saying the shorter life expectancy and greater risk are from the weight and that, by implication, reduction of weight will increase health. However, is this necessarily the case? The rest pay for their share," when will you be sending me a check to pay my doctor? If you stick to the original group of subjects and don't play games with the data, the data support a much lower estimate of risk from obesity. But, from a societal perspective, it's also a choice that impacts health care costs for everyone else. This will skew the results and mask the effects of the entire experiment. This influenced the results and compromised the validity of the experiment. But in studies where such factors as activity level, consumption of certain kinds of food, social factors such as socioeconomic levels and stress levels have been accounted for, weight becomes an almost non-existent factor. A central goal of most research is the identification of causal relationships, or demonstrating that a particular independent variable (the cause) has an effect on the dependent variable of interest (the effect). (Here is a reference that kind of, sort of explains how it is calculated now: http://health.howstuffworks.com/pregnancy-and-parenting/childhood-conditions/childhood-obesity1.htm), Here's the thing. Thanks for the thoughtful response, Stabby. It is why skinny people get disease and die to. Instead, the underlying assumption is that it is "obvious" that therefore people need to control their weight. Well I suppose I will be one who isn't offended and outraged by your post. Investigators also provided precise estimates of the increased risk of death among people who are overweight and obese. If I am right, then HAES will lead to good health no matter what someone's size is. 5. It was a choice I was making. Everyone who reads research critically starts with skepticism. This is where another event actually caused the effect noticed, rather than your treatment or manipulation. Here are 3 simple but effective methods: 5W1H, 6M and 8P method. ScienceDaily (Mar. Public Health Here's a good discussion of the problems with obesity research, including discussing the implications of the JAMA article: http://www.healthyweightnetwork.com/cntrovsy.htm#controvsy.htm, ================================================. eval(ez_write_tag([[300,250],'explorable_com-box-4','ezslot_1',262,'0','0']));The key principle of establishing cause and effect is proving that the effects seen in the experiment happened after the cause. As you have pointed out, cause and effect is extremely difficult to establish especially when it comes to human nutrition and health. Cause and Effect Definition. It is not obvious, and more importantly, it should not be assumed in science to be obvious. Above those points, the relative risk of death increased linearly with increased body mass indices in both men and women.". ====================================================. Reference The investigators noted the relationship between BMI and mortality may differ across racial and ethnic groups. And, btw, don't you think the cost of health care would be reduced significantly if every time an insured fat person went to the doctor their symptoms were ignore, they were given pills they don't need to lose weight and they are encouraged to have expensive surgeries that don't work or require multiple additional surgeries? A simple experiment utilizes a control group of participants who receive no treatment and an experimental … *People with higher BMIs have more cytokines from the stress of dealing with a social stigma on a daily basis and are therefore at higher risk for conditions that lead to early death.

So you have a personal stake, Anon... A good scientist always challenges his assumptions. This makes it exceptionally difficult for the researcher to state that their treatment is the sole cause, so any research program must contain measures to establish the cause and effect relationship. He describes a case history as an event or series of events set in an organisational framework with or without a related environment. Unlike in association studies, random assignment assures (if everything is designed correctly) that its the behavior being studied, and not some other random effect… Sensational numbers are better than small, hard to understand or overly large, beyond comprehension numbers. And, don't confuse the differnce between proof that losing weight helps with proof that getting obese in the first place is unhealthy.

As compared with a BMI of 22.5 to 24.9, the researchers report a 44 percent increase in risk of death for participants with a BMI of 30.0 to 34.9; an 88 percent increase in risk for those with a BMI of 35.0 to 39.9; and a 2.5 times (250 percent) higher risk of death for participants whose BMI was 40.0 to 49.9. I would disagree -- I think that if we ask the questions we are supposed to ask when reviewing research, then we can learn more not less. The first thing to remember with causality, especially in the non-physical sciences, is that it is impossible to establish complete causality. Ah! However, in other disciplines timing may not be a broad factor. It just happens to be an aspect of health policy that I have considerable personal experience. A study of more than 1 million adults in the United States (457,785 men and 588,369 women), investigated the relation between body mass index and the risk of death from all causes, cancer, and cardiovascular disease. Biases exist in all research. In the physical sciences, such as physics and chemistry, it is fairly easy to establish causality, because a good experimental design can neutralize any potentially confounding variables. Additional precision might be gained from larger cohort studies, but bias because of nonrepresentative samples and the use of self-reported weight and height could lead to less accurate estimates.". Are you teaching a psychology class? Results were broadly similar for men. The only way to do this is through a strong and well-considered experimental design, often containing pilot studies to establish cause and effect before plowing on with a complex and expensive study. Again, I think some people are missing the point. Also, it is very hard if not impossible to isolate variables in human studies. 6 Ways to Increase Happiness at Work and at Home. We need to follow the evidence the best that we can and try to draw meaningful conclusions when we can, but not at the expense of good science and meaningful and relevant applications. With the above example, an alcoholic drink manufacturer could use the second interpretation to claim that alcohol is not a factor in depression and that the responsibility is upon society to ensure that people do not become depressed. People who do not smoke do get cancer. What I say to my students who ask me how can anyone find the time to examine all the information coming at them and fully understanding it is: If you don't have the time to examine it, then don't repeat it. At that point, the information becomes a sacred cow instead of a proposition to be debated and examined. Cause and effect demonstrated by measuring the impact of the Independent Variable on the Dependent Variable. Establishing Cause and Effect Through Experiments 48. This means you're free to copy, share and adapt any parts (or all) of the text in the article, as long as you give appropriate credit and provide a link/reference to this page.

The world is filled with many people and some people are more interested and/or have more talents in examining certain kinds of data than others. Quantitative research design also tends to generate only proved or unproven results, with there being very little room for grey areas and uncertainty. I am not naive enough to claim that everyone just needed to "exercise self-control", all of that is strongly mediated by hormones which do become dysregulated after a time eating an unhealthy diet, this is been demonstrated by researchers time and time again, the so-call "yo-yo effect", it is because the body defends a particular fat mass depending upon hormonal and neurotransmitter signaling.

It isn't sexy or flashy and I think the media wants it to be and as a result we get this constant influx of information misrepresented and twisted usually for someone's financial gain. Many of these claims deviate from the scientific process and pay little heed to cause and effect, diluting the claims of genuine researchers in the field. I find the complexities of how the mind, the body and the social environment come together to create both health and illness fascinating and I hope future medical research will move in the direction of integration of these various systems to more holistically understand this wonderful thing called the human body. "Obese Workers Cost Workplace More Than Insurance, Absenteeism, According to New Study What if the case can be made that there is a genetic component? Please save your sympathy. So, many believe that some folks just would rather eat whatever they want than do the hard work necessary to overcome obesity. They found that healthy women who had never smoked and who were overweight were 13 percent more likely to die during the study follow-up period than those with a BMI between 22.5 and 24.9. Changes in the cause has to create a corresponding change in the effect. A considerable amount of psychological research uses the experimental method. Genetics? And a lot of fun. One notable example, by the researchers Balnaves and Caputi, looked at the academic performance of university students and attempted to find a correlation with age. They really do it. People like simple answers. http://jama.ama-assn.org/content/303/3/242.short (Note that the plateau occurred before Michelle Obama's current efforts.). NOW I know that you are personally invested in being right about the obesity model. By their own system of measurement, kids are no longer getting fatter. But you (and the people who wrote up the research) are making an assumption about causation. The placebo effect refers to the bias created when a subject is aware of the expected results or has ideas about his or her expected performance. 1. I love medical sociology and I love thinking critically about how people speak about the world. Statistical assessments of correlation are easily reported in percentages and thus often make the first paragraph or even the headline. There are hundreds of thousands, if not millions, of smokers who have quit for well past the five year mark. Percentages work better than totals. But after this decision was made, those working with childhood obesity conveniently forgot all these problems of measurement and started just talking about prevalence like they had hard data. Kids do not grow evenly over time and therefore what looks like a big weight gain might look like a growth spurt if you wait just a little. Other studies reported in the journal show that obesity appears particularly threatening in the presence of other health problems, such as poor muscle strength and depression. History is filled with examples of people who decide that a group is less than human (which is a hateful decision imho) and then decide that the thing to be done is "help these poor creatures" who cannot help themselves.

AND I said that there are lots of studies that demonstrate quitting smoking improves health of the individual (and btw, on the population level as well). So why are these points important? It will be interesting to see if similar correlations exist with other diseases associated with obesity, such as cancer and heart disease.". Which one of these studies follows the course of the same individuals as they move from one BMI category to another (gaining or losing) and studies the results of this change in BMI in their health status? really? An experiment with no established cause and effect, on the other hand, will be practically useless and a waste of resources. I'm encouraged by the number of younger people who are not dieting and I hope someday the trigger of the word "diet" and discussions of different regimens will not be so emotionally charged.

It's actually one of the best articles (if not the best) I've read on the subject - not only about obesity but explaining just how science works which many people are confused about. The questions I and others have raised regarding this body of evidence are legitimate questions of the data and the conclusions drawn from the data. How or why? Targeting obesity itself often stigmatizes a group of people which honestly does nothing to help the cause. This is one of the reasons cited for the strong link between health and socioeconomic status, which exists even if you account for access to health care. Key Terms. Finkelstein found that presenteeism accounted for as much as 56 percent of the total cost of obesity for women, and 68 percent for men. We have this new concept in our country I've heard labeled "healthism." An experiment tests the effect that an independent variable has upon a dependent variable but a correlation looks for a relationship between two variables. I am not sure this is an analysis of whether obesity is healthy, unhealthy or neutral, but instead a discussion about how we come to those conclusions. and, where is your science? Unfortunately it has become a taboo issue, the elephant in the room that no one knows how to approach. One great movie moment that demonstrates this principle is in the move Contact when Ellie (Jodie Foster) first hears the alien transmission and runs into the telescope control room screaming "make me a liar."

This is the key fact here. It also assumes that there is an obvious method of actually controlling weight. While correlational research is invaluable in identifying relationships among variables, a major limitation is the inability to establish causality. So thanks for the bibliography, but I think you've proven my point more than yours. Science must evolve and adapt and be willing to grow and change, it needs to be willing to reject its premise.
