School-based promotion of cessation support: reach of proactive mailings and acceptability of treatment in smoking parents recruited into cessation support through primary schools

Short-term effectiveness of the national German quitline for smoking cessation: results of a randomized controlled trial

BACKGROUND

The objective of the present study was to examine the short-term effectiveness of the national German quitline for smoking cessation.

METHODS

A parallel-group, two-arm, superiority, randomized controlled trial with data collection at baseline and post-intervention (three months from baseline) was conducted. Individuals were randomized to either the intervention group, receiving up to six telephone counselling calls, or the control group, receiving an active control intervention (self-help brochure). The primary outcome was the seven-day point prevalence abstinence at post-assessment. Secondary outcomes included changes in smoking-related cognitions and coping strategies from pre- to post-assessment, the perceived effectiveness of intervention components, and the satisfaction with the intervention.

RESULTS

A total of n = 905 adult daily smokers were assigned to either the intervention group (n = 477) or the control group (n = 428). Intention-to-treat analyses demonstrated that individuals allocated to the telephone counselling condition were more likely to achieve seven-day point prevalence abstinence at post-assessment compared to those allocated to the self-help brochure condition (41.1% vs. 23.1%; OR = 2.3, 95% CI [1.7, 3.1]). Participants who received the allocated intervention in both study groups displayed significant improvements in smoking-related cognitions and coping strategies with the intervention group showing greater enhancements than the control group. This pattern was also found regarding the perceived effectiveness of intervention components and the satisfaction with the intervention.

CONCLUSION

The present study provides first empirical evidence on the short-term effectiveness of the national German quitline for smoking cessation, highlighting its potential as an effective public health intervention to reduce the burden of disease associated with smoking.

Schools and Wastewater Surveillance: Practical Implications for an Emerging Technology to Impact Child Health

Since the start of the COVID-19 pandemic, wastewater surveillance has emerged as a public health tool that supplements traditional surveillance methods used to detect the prevalence of the SARS-CoV-2 virus in communities. In May 2020, the Houston Health Department (HHD) partnered with a coalition of municipal and academic partners to develop a wastewater monitoring and reporting system for the city of Houston, Texas. The HHD subsequently launched a program to conduct targeted wastewater sampling at 52 school sites located in a large, urban school district in Houston. Data generated by this program are shared with school district officials and nurses from participating schools. Although initial feedback from these stakeholders indicated that they considered the wastewater data valuable, the emergency nature of the pandemic prevented a systematic evaluation of the program. To address this gap in knowledge, the HHD and Rice University conducted a study to determine how wastewater data are used to make decisions about COVID-19 prevention and mitigation practices in schools. Our findings indicate that maximizing the utility of wastewater data in the school context will require the development of communication strategies and education efforts tailored to the needs of specific audiences and improving collaboration between local health departments, school districts, and school nurses.

A pilot summer day camp cooking curriculum to influence family meals

Background

Efforts to combat the epidemic of childhood obesity have approached the issue from many different angles, with a family approach being the gold standard. While most efforts focus on the parents, few have viewed the child as the agent of change. In this study, we explored the feasibility of implementing a cooking curriculum into a summer day camp to determine its reception and explore the potential of home reach.

Methods

In partnership with a local YMCA, a child-focused cooking curriculum was developed, designed to be delivered to various age groups with key nutritional messages. Interviews were conducted with participating children and their parents to determine acceptability and potential to influence the home environment as well as explore children’s understanding of nutrition and cooking topics.

Results

Children in the study ranged from 7 to 15 years of age. Children overwhelmingly enjoyed the cooking camp and talked about it with their parents at home. Almost all parents had plans to try the recipes at home, and many had already made one or more of the recipes.

Conclusions

It is feasible to incorporate cooking lessons into a children’s summer day camp, with some evidence of reach into the home. Future studies should evaluate children as agents of change in cooking and meal preparation, and assess if this could increase the number and quality of family meals.

Evaluation and Implementation of a Proactive Telephone Smoking Cessation Counseling for Parents: A Study Protocol of an Effectiveness Implementation Hybrid Design

Detrimental health consequences of smoking for both parents and children stress the importance for parents to quit. A Dutch efficacy trial supported the efficacy of proactive telephone counseling on parents. Still, how this program would function in "real world" conditions and how parents could be optimally reached is unclear. Therefore, this study will use an innovative method to examine the recruitment success of two implementation approaches (i.e., via a healthcare approach and a mass media approach) to test the (cost)effectiveness of the program. A two-arm randomized controlled trial and an implementation study (i.e., process evaluation) are conducted. Parents (N = 158) will be randomly assigned to the intervention (i.e., telephone counseling) or control conditions (i.e., self-help brochure). Primary outcome measure is 7-day point prevalence abstinence at three months post-intervention. Qualitative and quantitative research methods are used for the process evaluation. We expect that parents in the intervention condition have higher cessation rates than parents in the control condition. We also expect that the recruitment of parents via (youth) health care services is a more promising implementation approach compared to mass media. Results will have implications for the effectiveness of a proactive telephone counseling and provide directions for its successful implementation.

Parental Smoking Cessation: Impacting Children's Tobacco Smoke Exposure in the Home

OBJECTIVES

There is no safe or risk-free level of tobacco use or tobacco smoke exposure. In this randomized controlled trial, we tested a tobacco control intervention in families and specifically evaluated a tailored cessation intervention for the parents and/or caregivers (Ps/Cs) who were smokers while their children were simultaneously enrolled in tobacco prevention.

METHODS

Ps/Cs and children were recruited from 14 elementary schools across rural and urban settings. Approximately one-fourth (24.3%; n = 110) of the total Ps/Cs enrolled in the randomized controlled trial (n = 453) were smokers, predominantly women (80.9%), with a mean age of 37.7 years. (SD 12.2); 62.7% were African American, 44% had less than a high school education, and 58% earned <$20 000 annually. P/C smokers were offered a tailored cessation intervention in years 1 and 2. Self-report smoking status and saliva cotinine were obtained at baseline, the end of treatment (EOT) and/or year 2, and in the year 4 follow-up.

RESULTS

Ps/Cs in the intervention group showed a larger increase in self-reported smoking abstinence over time (EOT: 6.5% [SE = 5.7%]; year 4: 40.6% [SE = 5.7%]) than the control group (EOT: 0.0% [SE = 6.5%]; year 4: 13.2% [SE = 6.4%]; F = 4.82; P = .0306). For cotinine, the intervention group showed a decrease from baseline (239.9 [SE = 1.3]) to EOT 99.3 [SE = 1.4]) and then maintenance through year 4 (109.6 [SE = 1.4]), whereas the control group showed increases from baseline (221.1 [SE = 1.4]) to EOT (239.0 [SE = 1.4]) to year 4 (325.8 [SE = 14]; F = 5.72; P = .0039).

CONCLUSIONS

This study provides evidence that tailored cessation offered to Ps/Cs in their children's schools during their children's enrollment in tobacco prevention may contribute to more robust success in P/C cessation and a reduction of tobacco smoke exposure in children.

The longitudinal, bidirectional relationships between parent reports of child secondhand smoke exposure and child smoking trajectories

This study examines the longitudinal relationships between child smoking and secondhand smoke exposure (SHSe). Participants were 222 parent-child dyads. The parents smoked, had a child with (48%) or without asthma, and were enrolled in a smoking/health intervention. Parent-reported child SHSe was measured at baseline and 4, 6, and 12-month follow-ups; self-reported child smoking was assessed at these points and at 2-months. A parallel process growth model was used. Baseline child SHSe and smoking were correlated (r = 0.30). Changes in child SHSe and child smoking moved in tandem as evidenced by a correlation between the linear slopes of child smoking and SHSe (r = 0.32), and a correlation between the linear slope of child smoking and the quadratic slope of child SHSe (r = - 0.44). Results may inform interventions with the potential to reduce child SHSe and smoking among children at increased risk due to their exposure to parental smoking.

Promoting smoking cessation among parents: effects on smoking-related cognitions and smoking initiation in children

BACKGROUND

Parental smoking is associated with an increased risk of smoking among youth. Epidemiological research has shown that parental smoking cessation can attenuate this risk. This study examined whether telephone counselling for parents and subsequent parental smoking cessation affect smoking-related cognitions and smoking initiation among children of smoking parents.

METHODS

Data of a two-arm randomized controlled trial were used in which 512 smoking parents were recruited into cessation support through their children's primary schools. After the baseline assessment, smoking parents were randomly assigned to tailored telephone counselling or a standard self-help brochure. Parental cessation was measured as 6-month prolonged abstinence at the 12-month follow-up. Children's smoking-related cognitions and smoking initiation were examined at 3-month, 12-month, and 30-month follow-up.

RESULTS

No statistical evidence was found that children of parents who received telephone counselling tailored to smoking parents or children of parents who achieved prolonged abstinence differ in smoking-related cognitions (i.e., smoking outcome expectancies, perceived safety of smoking, self-efficacy to refrain from smoking, susceptibility to smoking) or smoking initiation rate on any follow-up assessment.

CONCLUSIONS

This study is the first to examine the effects of an evidence-based smoking cessation treatment for parents and treatment-induced parental smoking cessation on cognitive and behavioural outcomes among children. Although descriptive statistics showed lower smoking initiation rates among children of parents who achieved prolonged abstinence, there was no statistical evidence that telephone counselling tailored to parents or treatment-induced parental smoking cessation affects precursors of smoking or smoking initiation among youth.

Predictors of cessation treatment outcome and treatment moderators among smoking parents receiving quitline counselling or self-help material

OBJECTIVE

Several cessation treatments effectively enhance cessation, but it is not always clear which treatment may be most suitable for a particular client. We examined predictors of treatment outcome and treatment moderators among smoking parents in the Netherlands.

METHOD

We conducted secondary analyses of a randomized controlled trial in which smoking parents received either quitline counselling (n=256) or a self-help brochure (n=256). Data collection was completed in October 2012. Endpoints were 7-day point prevalence abstinence and 6-month prolonged abstinence at 12-month follow-up. Potential predictors and moderators included socio-demographic characteristics, smoking-related variables, and child-related variables.

RESULTS

Male gender, higher employment status, lower daily cigarette consumption, higher levels of confidence in quitting, presence of a child with a chronic respiratory illness, and wanting to quit for the health of one's child predicted abstinence at 12months. Significant treatment moderators were intention to quit and educational level. Quitline counselling was effective regardless of intention to quit and educational level, but self-help material was less effective among less motivated and lower educated parents.

CONCLUSION

Certain subgroups of smokers, such as parents who are concerned about the health of their child, are particularly receptive to cessation support. Individual characteristics should be considered in treatment selections.

Self-efficacy and acceptance of cravings to smoke underlie the effectiveness of quitline counseling for smoking cessation

BACKGROUND

Few studies have examined why smoking cessation interventions are effective. The aim of this study was to examine the mediating processes underlying the effectiveness of cessation counseling administered by the Dutch national quitline.

METHODS

Data were used of a two-arm randomized controlled trial in which smoking parents, who were recruited through primary schools in The Netherlands, received either quitline cessation counseling (n=256) or a self-help brochure (n=256). The endpoint was 6-months prolonged abstinence at 12-months follow-up, with 86.7% outcome data retention. Putative psychological mediators of treatment effectiveness included smoking-related cognitions (positive smoking outcome expectancies, self-efficacy), emotions (negative affect, perceived stress, depressive symptoms), and smoking cue coping methods (avoidance coping, acceptance coping) assessed at 3-months post-measurement.

RESULTS

Quitline cessation counseling significantly decreased positive smoking outcome expectancies and negative affect and increased self-efficacy to refrain from smoking, avoidance of external cues to smoking, and acceptance of internal cues to smoking compared to self-help material. Increased self-efficacy to refrain from smoking in stressful and tempting situations (p<.001) and increased acceptance of cravings to smoke (p<.001) significantly mediated the effect of quitline cessation counseling on prolonged abstinence at 12-months follow-up (explained variance: 25.1%).

CONCLUSIONS

Self-efficacy to refrain from smoking and acceptance of cravings represent an important source of therapeutic change in smoking cessation counseling.

Effectiveness of proactive quitline counselling for smoking parents recruited through primary schools: results of a randomized controlled trial

AIMS

To test the effectiveness of tailored quitline (telephone) counselling among smoking parents recruited into cessation support through their children's primary schools.

DESIGN

Two-arm randomized controlled trial with 3- and 12-month follow-up.

SETTING

Proactive telephone counselling was administered by the Dutch national quitline.

PARTICIPANTS

Smoking parents were recruited through their children's primary schools and received either intensive quitline support in combination with tailored supplementary materials (n = 256) or a standard self-help brochure (n = 256).

MEASUREMENTS

The primary outcome was 7-day point-prevalence abstinence at 12-month follow-up. Also measured were baseline characteristics, use of and adherence to nicotine replacement therapy and pharmacotherapy, smoking characteristics and implementation of a home smoking ban.

FINDINGS

Parents who received quitline counselling were more likely to report 7-day point-prevalence abstinence at 12-month assessment [34.0 versus 18.0%, odds ratio (OR) = 2.35, confidence interval (CI) = 1.56-3.54] than those who received a standard self-help brochure. Parents who received quitline counselling were more likely to use nicotine replacement therapy (P < 0.001) than those who received a standard self-help brochure. Among parents who did not achieve abstinence, those who received quitline counselling smoked fewer cigarettes at 3-month (P < 0.001) and 12-month assessment (P < 0.001), were more likely to make a quit attempt (P < 0.001), to achieve 24 hours' abstinence (P < 0.001) and to implement a complete home smoking ban (P < 0.01).

CONCLUSIONS

Intensive quitline support tailored to smoking parents is an effective method for helping parents quit smoking and promoting parenting practices that protect their children from adverse effects of smoking.
