Assignment 4: Creating graphs for your data

In this study, we are interested to see the correlation between the quantity of smoked tobacco and the smokers who try more than one tu cut down with tobacco.

The first Variable is S3AQ8A6′‘More than one try to  stop/ cut down with tobacco’‘. It is a categorical variable. The SAS program to have a bart chart is bellow:

The bar chart shows the percent of smokers more then one try to cut down or stop thtobacco,  about 44%, as indicated by the reponse code of one (yes they do). And those who didn’t try, about 55,6% indicated by 2.

The second variable is the quantity of tobacco use:  

The bar chart:

The bar chart show us that 30% of smokers smoke 600 cigarettes per month. This point represent the peakness of this bar chart.

the correlation between its 2 variables gives us the following result:

the obtained bar chart is the following

So we can see from this graph that the more the number of packets consumed the more the attempts to cut down with tobacco use decrease.  Among those smoking 0 to 1 packs per month try 1,8 more than once to cut down with tobacco but couldn’t. on the other hand those smoking greater than 60 packs per month try 1,4 more than once to stop tobacco.

Results:

Description

In this work i made a combination between several variables.People who more than one try to cut down with tobacco use but found couldn’t are(S3AQ8A6)  63% of current user (SMOKER). The Usual smoking frequency day per month (USFREQMO) show that 91,67% of participants smoke every day with a number of cigarettes used by month is 87,44% grater then 100 cigarettes (NUMCIGMO_EST). These results may explain the feeling of depression felt following cut down on tobacco use observed on 72,90% of participants in this study (S3AQ8A7A).

Assignment 2: Running your first program SAS

- 1 My program:

2- Frequency tables:

3- Description

The main goal of this research is to find out what the association between variables 1 (SMOKER), 2 (S3AQ8A6) and 3 (S3AQ8A7A). As a result we can see that 100% of the current user of tobacco try to stop/ cut down on tobacco but found couldn’t.  The frequency is more important before 12 months (93;09%) ago then happen in last 12 months (74,21%). The question is this result due to depression after stopping tobacco use? the frequency tables showed that current user of tobacco feel depressed after stopping tobacco ,use  (72,17%) and it is more important in last 12 months.

This result load us to think of there is a link with the nicotine dependence. And the question will be: Is nicotine dependence induce depression after stopping tobacco, the cause that prohibit current user of tobacco to cut down with tobacco use? for another association to test.

Is the failure to cut down on tobacco use associated with tobacco use status and the feeling of depression after stopping tobacco use

After looking through the codebook for NESARC study. The section 3: tobacco use and dependence caught my attention and more specifically I was interested on cutting down on tobacco use.My friends and relatives who use tobacco say that more we use tobacco the more we can’t stop it. It becomes a habit. The, I decide to explore the association between tobacco use status and more than once try to stop/ cut down on tobacco use but found couldn’t. On the other hand, I wonderabout the causes that prevent smokers from cutting tobacco. Does  smokers return to tobacco because they feel depressed and they only tobacco use could help them?? An association between:’’ more than once try  to stop/ cut down on tobacco use but found couldn’t’’ and ‘‘ever feel depressed after stopping or cutting down on tobacco use.

After the litterature reviews I find a positive correlation between requency of tobacco use and the failure on stopping tobacco. On the other side, multiple items describe depression associated with the cutting down on tobacco but also I don’t find the answer about is it depression that derived back to tobaco use.
