Objectives. The aim of this study was to evaluate smoking trends among Span
ish men and women by social class between 1987 and 1997.
Methods. We used secondary analysis of the National Health Interview Survey
s of 1987,1993,1995, and 1997. The main outcome measures were prevalence of
smoking, smoking cessation activity (quit ratio), and smoking initiation i
n the manual and nonmanual social class in each year and smoking prevalence
ratio, smoking cessation ratio, and smoking initiation ratio in 1997, vers
us 1987 in each social class.
Results. Among men ages 25 years and older the prevalence of smoking in bot
h the manual and the nonmanual social class decreased between 1987 and 1997
in all age groups, and the relative magnitude of the decrease was always g
reater in the nonmanual social class. In contrast, among women the prevalen
ce of smoking increased in both social classes: in the 25- to 44-year age g
roup the smoking prevalence ratios in 1997 versus, 1987 were 1.20 in the no
nmanual social class and 1.61 in the manual social class, while in the 45-
to 64-year age group the prevalence ratios were 2.52 and 2.15, respectively
. The quit rate among men increased in both social classes in all age group
s between 1987 and 1997; in contrast, among women the quit rate increased o
nly among those ages 25 to 44 years in the nonmanual social class. Smoking
prevalence for people ages 16 to 24 years-smoking initiation-decreased amon
g men and women between 1987 and 1997 in both social classes.
Conclusions. Smoking trends in Spain by social class have differed among me
n and women. The findings are considered in the context of policies and pro
grams aimed at reducing smoking. (C) 2001 American Health Foundation and Ac
