Adolescent Smoking and Development of Long-Term Habits: A Longitudinal Analysis in SAS Presented: San Francisco, CA, SAS Global Forum, April-May 2013.

This study was an investigation into the impact of early adolescent smoking on adult smoking habits of National Longitudinal Survey of Youth 1997 Participants over the course of 13 years. The data was from a survey consisting of 1,212 individuals interviewed once a year for 13 years (1997 to 2009) with the frequencies and amounts of cigarettes smoked recorded. SAS® was used for the analysis and SAS arrays, do loops and macros were used in structuring the data. There is significant evidence that smoking habits increase over time, sex, and age when started smoking have an effect on number of cigarettes smoked, and the number of cigarettes increases as the number of peers who smoke and does drugs increases. |

Historically, deaf education in the United States has achieved poor results. An oft-quoted statistic is that on average, deaf students graduating from high school (at age 18-21) perform at the level of hearing 8-10 year olds in terms of reading and writing skills (Allen, 1994; Traxler, 2000). Performing secondary analyses on the Children of the National Longitudinal Survey of Youth (NLSY) focusing on developmental and educational outcomes allows one to predict growth patterns in each for deaf and hearing children. Children were flagged as deaf by careful deliberation of multiple questions to indicate hearing status. A sibling of each deaf child was picked as a means of comparison, to control for home environment. The use of frequencies, means, and growth models disproves many past assumptions and raises some interesting questions. |
