[Meta-analysis of effects on adolescent smoking cessation programs in Korea]

Meta-analysis of the effects of smoking prevention programs for young adolescents

Purpose

This meta-analysis aimed to analyze the effects of smoking prevention programs for young adolescents at early smoking stages to identify the appropriate characteristics of prevention programs for this population.

Methods

Searches of health-related databases and Google Scholar were conducted, and 23 randomized studies were included in the analysis. The main outcome variable was smoking behavior. The analysis was conducted using Comprehensive Meta-Analysis software (version 3.0).

Results

Smoking prevention programs significantly reduced smoking behaviors (OR=0.85, 95% CI=0.77-0.93). School-based programs (OR=0.79, 95% CI=0.75-0.83), programs by trained teachers or educators (OR=0.77, 95% CI=0.71-0.83), high-intensity programs (OR=0.82, 95% CI=0.75-0.91), and programs in an in-school setting (OR=0.82, 95% CI=0.74-0.90) had the most significant effect on reducing smoking behavior.

Conclusion

For young adolescents, smoking prevention programs are most effective when they are school-based or highintensity programs, and when conducted by teachers or educators with proper training. Further studies are required since there was insufficient research to explore the effect of web-based programs or family-centered programs on adolescent smokers.

Predicting Old-age Mortality Using Principal Component Analysis: Results from a National Panel Survey in Korea

Background and Objectives: This study aimed to group diseases classified by the International Classification of Diseases using principal component analysis, and discuss a systematic approach to reducing the preventable death rate from a perspective of public health. Materials and Methods: Using a 10-year follow-up analysis of the Korean Longitudinal Study of Aging (KLoSA) data, this study obtained de-identified data including participants’ data of community-dwelling individuals aged ≥45 years from 2006 to 2016. Participants were randomly selected using a multistage, stratified probability sampling based on geographical area and housing type. We excluded 37 participants with missing information at baseline and included 10,217 study participants. This study used the principal component analysis to extract comorbidity patterns, and chi-square test and Cox proportional hazards models for analyzing the association between the factors of interest. Results: Principal component 1 (diabetes, heart disease, and hypertension) was associated with an increased hazard ratio (HR) of 1.079 (95% confidence interval (CI) 1.031–1.129, p = 0.001). Principal component 3 (psychiatric and cerebrovascular diseases) was related to an increased HR of 1.134 (95% CI 1.094–1.175, p < 0.0001). Moreover, principal component 4 was associated with a high HR of 1.172 (95% CI 1.130–1.215, p < 0.0001). However, among participants aged between 45 and 64 years, principal component 4 showed a meaningfully increased HR of 1.262 (95% CI 1.184–1.346, p < 0.001). In this study, among the four principal components, three were statistically associated with increased mortality. Conclusions: The principal component analysis for predicting mortality may become a useful tool, and artificial intelligence (AI) will improve a value-based healthcare strategy, along with developing a clinical decision support model.

Three-month effects of Project EX: A smoking intervention pilot program with Korean adolescents

Despite current prevention and cessation efforts, adolescent smoking remains a pressing issue worldwide, including in Korea. The current study evaluates Project EX-Korea, a teen tobacco use cessation program, three months after baseline. The quasi-experimental trial intervention involved 160 smokers in 10th to 12th grade, 85 from the program condition schools and 75 from the control. At three-month follow-up, the intent-to-treat (ITT) quit rate in the program group (30.2%) was 3.6 times that of the rate in the standard care control group (9.2%; p < 0.05). Among those who did not quit, those in the program group smoked less on average than those in the control group, but there was no difference in follow-up mFTQ scores between the two non-quitter groups. As teen tobacco use cessation programming is much needed in Korea, Project EX is a plausible program to implement among Korean adolescents.

•

Teen tobacco use cessation programming is still much needed in Korea and worldwide.

•

Project EX is a credible tobacco cessation program to help Korean adolescents quit.

•

The program group's quit rate was 3.6 times that of the control group's quit rate.

•

Non-quitters in the program group smoked less than those in the control group.

[Effects of a Strength Based I-Change Smoking Cessation Program for Smoking Middle School Boys]

PURPOSE

This study was done to develop a strength based I-change smoking cessation program for middle school boys and identified its effects.

METHODS

The study design was a nonequivalent control group pre-post test design. The participants were 97 middle school students from D city, who were in school from April 6 to September 25, 2015. The experimental group participated in the strength based I-change smoking cessation program, while the comparative group participated in a general smoking cessation program. The control group did not participate in any program. Data analyses involved χ²-test, Fishers' exact test, Bonferroni test, and Repeated measures ANOVA, with the IBM SPSS for Windows (version 20.0) program.

RESULTS

Compared to the comparison and control groups, the experimental group showed significant improvement in knowledge, attitude, self-efficacy, behavior change. Also cotinine in urine and modeling of social influence in the experimental group significantly decreased after the strength based I-change smoking cessation program.

CONCLUSION

These findings indicate that the strength based I-change smoking cessation program is an effective intervention for middle school boys who smoke. The findings suggest that such programs can be used at public health centers or through school health education to decrease smoking in adolescents.

[Effect of school-based peer leader centered smoking prevention program]

PURPOSE

The purpose of this study was to develop and evaluate a school-based peer leader centered smoking prevention program.

METHODS

Non-equivalent control group with a pre/post-test design was used. Students (n=174) in two boys' junior high schools located in D city, Korea participated with 85 being selected for the experimental group and 89 for the control group. Five sessions were given to the experimental group and a 50 minute lecture to the control group. Knowledge, attitude, non-smoking intention, and non-smoking efficacy were measured for the both experimental and control group at two weeks before the program and one month after the program was completed. Data were analyzed using χ²-test, Fisher's exact test, independent t-test and paired t-test with the SPSS 21.0 program.

RESULTS

The experimental group showed higher overall knowledge, negative attitude toward smoking, and higher non-smoking intention and efficacy. After receiving the school based peer leader centered smoking prevention program scores for attitude toward smoking and non-smoking efficacy increased in the experimental group were higher than in the control group.

CONCLUSION

The school-based peer leader centered smoking prevention program needs longitudinal evaluation, but from this study, there is an indication that this program can be used with junior high school students and effectively change students' attitude toward smoking and promote non-smoking efficacy.

Alcohol, tobacco, and other drug misuse prevention and cessation programming for alternative high school youth: a review

BACKGROUND

Relative to youth in regular high schools, alternative high school (AHS) youth are at high risk for alcohol, tobacco, and other drug (ATOD) misuse. Prevention and cessation efforts are needed for this population.

METHODS

A systematic, exhaustive literature search was completed to identify ATOD misuse prevention and cessation research studies with AHS youth.

RESULTS

For the AHS population, 23 ATOD misuse prevention or cessation program evaluations were located. This review indicated that successful efforts have focused on instruction in motivation enhancement, life coping skills, and decision making.

CONCLUSIONS

Alcohol, tobacco, and other drug misuse prevention and cessation programming for AHSs is effective, delivered in the classroom or as a school-based clinic. There is little evidence, though, that this programming is effective when delivered through other modalities such as via computer or bridging beyond the school setting. More research and application of evidence-based programming are recommended for youth in AHS settings.

[Effectiveness of a motivational interviewing smoking cessation program on cessation change in adolescents]

PURPOSE

This study examined the effectiveness of an Adolescent Motivational Interviewing Cessation program on smoking cessation change. The study was done with a nonequivalent control group pretest-posttest design.

METHODS

The participants were 39 high school students from G city, who were in school from September 1 to October 30, 2009. The students were assigned to the experimental group (20) and participated in the motivational interviewing cessation program or to the control group (19) who did not participate. Data analyses involved χ²-test, independent t-test, Repeated Measures ANOVA, and utilized the SPSS program.

RESULTS

The experimental group had significantly less daily smoking, nicotine dependence and smoking temptation in comparison to the control group. The experimental group had significantly higher stage of change in comparison to the control group.

CONCLUSION

The results of the study indicate that a motivational interviewing cessation program delivered to adolescents who smoke is an effective method of encouraging cessation, and can be utilized as an effective nursing intervention for adolescents who smoke.

A meta-analysis on the effectiveness of computer-based education in nursing

Objectives

The purpose of this study was to conduct a comparative analysis of education effectiveness between computer-based education and traditional education methods in nursing.

Methods

Medical and nursing literature databases were searched to identify studies regarding the effectiveness of computer-based education in nursing. Overall effect sizes for three outcome variables (knowledge, attitude, and practice level) were calculated. The effects of study characteristics on the outcome variables were analyzed.

Results

Twenty-seven studies published from 1990 to February 2009, which that met the inclusion criteria, were included in the analysis. The meta-analysis showed that computer-based education generally had positive effects on knowledge, attitude, and practice, with overall effect sizes of 0.43, 0.35, and 0.34, respectively. This study also showed that the type of learner and the total education period had different effects on knowledge.

Conclusions

This metaanalysis found that computer-based education in nursing had positive effects on knowledge, attitude, and practice.
