Changes in youth cigarette use and intentions following implementation of a tobacco control program: findings from the Florida Youth Tobacco Survey, 1998-2000.

CONTEXT: Many states are developing tobacco use prevention and reduction programs, and current data on tobacco use behaviors and how these change over time in response to program activities are needed for program design, implementation, and evaluation. OBJECTIVES: To assess changes in youth cigarette use and intentions following implementation of the Florida Pilot Program on Tobacco Control. DESIGN, SETTING, AND PARTICIPANTS: Self-administered survey conducted prior to program implementation (1998), and 1 and 2 years (1999, 2000) later among a sample of Florida public middle school and high school students who were classified as never users, experimenters, current users, and former users of cigarettes based on survey responses. MAIN OUTCOME MEASURES: Changes in cigarette use status, intentions, and behaviors among students over a 2-year period. RESULTS: Surveys were completed by 22,540, 20,978, and 23, 745 students attending 255, 242, and 243 Florida public middle and high schools in 1998, 1999 and 2000, respectively. Response rates for the 3 survey years ranged from 80% to 82% and 72% to 82% for the middle school and high school surveys, respectively. After 2 years, current cigarette use dropped from 18.5% to 11.1% (P<.001) among middle school students and from 27.4% to 22.6% (P =.01) among high school students. Prevalence of never use increased from 56.4% to 69. 3% (P<.001) and from 31.9% to 43.1% (P =.001) among middle school and high school students, respectively. Prevalence of experimenting decreased among middle school and high school students from 21.4% to 16.2% (P<.001) and from 32.8% to 28.2% (P<.001), respectively. Among never users, the percentage of committed nonsmokers increased from 67.4% to 76.9% (P<.001) and from 73.7% to 79.3% (P<.001) among middle school and high school students, respectively. Among experimenters, the percentage of students who said they will not smoke again increased from 30.4% to 42.0% (P<.001) in middle school and from 44.4% to 51.0% (P<.001) in high school. CONCLUSIONS: Progress toward reduction of youth tobacco use was observed in each of the 2 years of Florida's Pilot Program on Tobacco Control. Our results suggest that a comprehensive statewide program can be effective in preventing and reducing youth tobacco use. JAMA. 2000;284:723-728

Editing data: what difference do consistency checks make?

In 1998, the Florida Department of Health undertook a self-administered school-based survey of tobacco use, attitudes, and behaviors among nearly 23,000 public school students in grades 6-12. The survey design did not use skip patterns; therefore, students had multiple opportunities to contradict themselves. By using examples from the high school portion (grades 9-12) of the survey, the authors examined five possible approaches to handling data inconsistencies and the effect that each has on point estimates. Use of these approaches resulted in point estimates of current cigarette use ranging from 25.6% to 29.7%. The number of missing respondents varied from 33 (less than 1%) to 1,374 (13%), depending on which approach was used. After stratification by gender and race, the prevalence estimates changed marginally for girls but strikingly for boys. Non-Hispanic White students were substantially more likely than non-Hispanic Black students to report current cigarette use, but the magnitude of this difference varied significantly according to the analytical approach used. The approach used to check data consistency may influence point estimates and comparability with other studies. Therefore, this issue should be addressed when findings are reported.

Do ethnic differences in dietary cation intake explain ethnic differences in hypertension prevalence? Results from a cross-sectional analysis.

PURPOSE: To better understand how the magnitude of the association between ethnicity and hypertension is affected by ethnic differences in dietary cation intake, we describe differences in dietary cation intakes and prevalence of hypertension across four ethnic groups (African-Americans, European-Americans, Mexican-Americans, and Puerto Ricans). We also assess the cross-sectional association between: (i) hypertension and self-reported dietary intakes of sodium, potassium, and calcium for each ethnic group; and (ii) ethnicity and hypertension before and after adjustment for dietary cation intakes. METHODS: Data from the Second National Health and Nutrition Examination Survey (1976-1980) and the Hispanic Health and Nutrition Examination Survey (1982-1984) were analyzed. Multiple logistic regression was used to estimate odds ratio (OR) for hypertension for each ethnic group, with adjustment for age, body mass index (BMI), and diabetes status. Comparisons were made to assess whether the magnitude for the ethnicity ORs changed when the three nutrient variables were entered into the model. RESULTS: Mexican-American and Puerto Rican men and women showed clinically and statistically significantly higher mean intakes of the three cations than did African-American men and women, who reported clinically and statistically significantly lower mean intakes of sodium, potassium, and calcium than did European-American men and women. Mean dietary intakes of potassium and calcium were higher for normotensives than for hypertensives among all ethnic groups, except African-American and Mexican-American women. In multivariate modeling, stark differences in ORs for hypertension persisted across ethnic groups despite inclusion of the nutrient variables. CONCLUSION: In this cross-sectional study, adjustment for dietary cation intakes did not alter the magnitude of the ethnic differences in prevalence of hypertension.
