Question 3
One of the studies strengths is that it does look at long term affects. Do you think it received different results than other clinical trials because of its length or other factors such as less error in diet recall, or types of protein?

I think that it would receive different results for several reasons, but mostly because the longer you eat a certain way the more it will effect you body. But other factors within the scope of length could be time to see errors, normal effects of aging, etc.
The researchers emphasize the fact that what sets this study apart is it's length and focus on animal vs vegetable protein. I'm sure that both of these factors are responsible for the difference in results, but I didn't notice if the other clinical trials they were referencing were from the same time period or not. This could be a factor since the research is so old.
I think different results may have been obtained since it did look at long term affects. Many studies do not look at long term affects so the results are often very different. I don't think the other factors would have caused the results to vary as much as looking at the effects over a long period of time. They may cause a slight variation but I don't think it would be very much.
I agree with Kathy that the other studies being referenced could have been from a different time period causing differences in results. I also agree with Tiffany that normal effects of aging could also effect results over a long period of time. It would be interesting if the study was repeated using that factor as well as the others.
I think that it is possible that the more time a study covers, the more likely results could differ. Also, when a study covers a longer period of time, this provides the researchers with more data to analyze and could lead to more accurate results. I think it is possible that using Burke’s diet history and observing both animal and plant protein intakes could have lead to different results compared to other studies because this was a different approach to collecting data.
I believe the study reported that their results were not conclusive with other clinical trials because the of length differential. I agree with Tiffany about the eating habits and how those long-term habits affect our bodies. Kathy also makes a good point on the studies that were used in reference (specific to the time period) and their validity and reliability for comparison.
I think a long-term study was the right type for the question these researchers were asking because it shows the effect on body composition of protein in the diet, which doesn't change quickly. Studies that look at the effect of protein on weight over a short time period may show that protein has an effect in some people on metabolism, glycemic control, etc. (and thus effects weight loss) but that is different than body composition.
I agree with Meg on this. I do not think a short-term study could have provided appropriate information in this specific situation
I think all of these factors contribute to the different results. The largest contributor would probably be the fact that the study was long term. The subjects had more time to show the researchers a dietary pattern and therefore the researchers could draw more accurate conclusions. I also think that looking specifically at plant and animal protein intake over a long period of time shows how those different proteins truly affect our bodies.
I agree with Tiffany that the major reason long term affects are so important in this study is that the longer we eat a certain way, the more our body will be affected positive or negatively.
I also agree with Amanda that this study really cannot compare to similar studies because of the lenght of this research. I also agree with Meg that a short term study would not have been appropriate for the goals of this research
The longer the study the better understanding the researchers has of the population in the study. The participants would also become better at completing a diet recall over time.
I agree with Tiffany's point about the longer people eat a specific way, the more likely it will affect their bodies. In a large amount of studies when we take dietary recalls very few times over a short time-span, we aren't positive if this is how the individual normally eats or if it was simply an off day. The person could even be going through health-kick or attempting a diet. By observing the participants over a longer period of time, we are better able to see those patterns.
Few studies look at long term effects and so this study is unique in that it had that opportunity. I think it may have shown different results because it was able to look long term instead of directly after the study was completed.
Meg made an interesting point that this study would yield different answers with short term data. It would look more at body composition and BMI would be ineffective.
