INTRODUCTION
The habit of smoking is considered a true drug addiction and
is widespread all over the world; 47% of males and 12 % females smoke (1), causing
cardiovascular illness and death by cancer of the lungs and pharynx (2).
Countries with low level of socio economic development occupy the first places in the rank of the greatest number of smokers with more than 15 years of habit. Our country occupies place 46º, with a prevalence of 35% in people older than 15 years old (3).
The habit is accepted socially in communities of adults of both sexes and it has lately extended to teenagers, influenced by causes tant tend to improve their social status and other causes. Adults and young people begin smoking during their university life, but in the past few years young people began to smoke earlier, during their high school period.
That's why we ask ourselves: Where and at what age does the habit begin nowadays? Are high schools fertile ground for the beginning of the habit? Which are the causes for the beginning of smoking? Which is the influence of school and home? These questions are the starting point for the studies in order to find the answers.
OBJECTIVES
To determine the prevalence over: a) The habit of smoking
in students, b) Causes for the beginning, c) Influence of school and home on
high school students of the capital city of Santiago del Estero.
MATERIAL AND METHODS
The design of the studies, is plannified to present a scientific
problem of quantification (descriptive), prospective, observational and transversal
(4). The population studied: High School students attending schools in the city
of Santiago del Estero. The study was made in three steps:
1st. Step: discussion and information about the habit of smoking and its consequences, through several months using Programmed Conferences given by medical doctors, using didactical material and giving information about the components of cigarettes , organic consequences, physical and psychological consequences, etc.
2nd. Step: Fulfillment of the anonymous survey , coordinated by a teacher, looking for spontaneous and true answers, without guidance.
3rd. Step: charge of data and analysis. The studied variables are seen in the 29 questions in the survey, with the option of suggested answers, such as a) college, course and time of attending school b) age, sex, and districts where they live c) parents activities d) students knowledge about the habit of smoking e) information about parents and teachers´ habits f) level of information about smoking g) substances present in cigarettes h) organs that are affected and illnesses produced by the habit of smoking.
Statistic analysis: Data was placed in a base of related data Foxpro2,5 (5) and then analyzed using statistic program (Statgraphics V.5.0 (6). We analyzed these data for : a) categorical variables : distribution of frequencies and/or percentages and b) variables in superior scale: parameters that resume measures of central tendency and dispersion (7). The manuscript was made with word processor.

DISCUSSION
The studied population represents approximately 70% of high
school students of the capital city of Santiago del Estero. It constitutes a
representative sample. The global prevalence of the main capitals of the world
in relation to our study has is lower than in other studies. Germany (7,7%)
(8) and Mexico (9,1%) and very low compared with the rest of the mentioned capitals,
with an average of 35,5%, with similar ages.
Different works in the entire world show the prevalence of the habit of smoking among students. The study made in Oklahoma (10) established the prevalence of 21% in young adults, the prevalence of feminine sex, with an during high school time up to 38%, percentage that reduces after graduation (28%).
The study establishes as conclusion that preventive actions through campaigns make the habit decrease between 8 and 9 th grades. Those actions produce more important positive impacts as measures to prevent the habit in adults.
The prevalence of the habit in German colleges varies according to the considered level. GYMNASIUM presents prevalence of 2,7%, different from HAUPTSCHULE with 14,3 % or KEALSCHULER with 5,6 % , or GESAMTSCHULE with 8,2%.
The study with the method of the anonymous survey made in Barcelona (11) over students of the 8th. Grade (ages 13 to 14), reveals that adolescence is an important period to develop preventive actions to try to avoid smoking in adults. The results show: teenagers present prevalence of 10,9 % without sex differences. The conclusion is the increase of the habit in school population.
A national survey in France (12) considering teenagers and adults show the decrease of smoking in both sexes teenagers (16%) along 14 years of control. Boys from the 10th. grade of the Canadian School (13) showed prevalence of the habit of 28 %. In senior and junior high schools in the rural area of Oregon, United States (14), there exists a prevalence of 39 % of the habit of chewing tobacco, 7 % corresponding to women, which is considerably high for this form of addiction.
Non students teenagers from Chile (15) are: usual smokers 3640 % (older than 10 years old) and 48 % (older than 15 years old). The results are different in Chinese cities, with almost no smoking women ( 2%)(16), different from men who began smoking between 2024 years old (52%) as a consequence of customs and beliefs of oriental women.
An anonymous survey (17) in 3.623 teenagers of 8 schools of Northern England, reveal prevalence of 21 %, more women than men, the same prevalence as in bulimic girls in Japan. (18) The global average prevalence of smoking habit in student teenagers and non student teenagers in the world is about 25%. (Table 6).
CONCLUSIONS
a) The low prevalence, in relation to other countries and
the world average, with predominance of feminine sex, state colleges, in students
of 1415 years old, that regularly are in 3rd4th grades.
b) There exists influence of home and colleges as initial places for the habit.
c) Teenagers smoke less than 10 cigarettes per day, with election of blonde tobacco; more frequent with friends and classmates.
d) The influence of the students own classmates is a great influence for the beginning of the habit of smoking; then they go on smoking because they like it.
e) High school students of Santiago del Estero have an adequate level of information about addictions, and they know what happens to the body, with the exception of heart illnesses.
