Health Impact of Secondhand Smoke Exposure (SHSe) on Children

• SHSe is causally associated with the development of a variety of

pediatric respiratory tract problems, including asthma,2respiratory syncytial virus (RSV), middle ear disease, pneumonia and bronchitis, upper respiratory tract infections, as well as Sudden Infant Death Syndrome

• For every 100,000 U.S. children, at least 1000 excess respiratory

infections and 500 excess hospitalizations have been attributed to SHSe

• Annual healthcare expenditure directly related to SHSe is

approximately $5 billion with another $5 billion in indirect expenses.

• Upwards of 40% of all U.S. children are exposed to SHS, with low-

income minority children having rates of exposure up to 68%, suggesting that the risks of SHS exposure are widespread.

Dissemination and Implementation

• Interventions need to include individual

and organizational level components

• Best integrated within existing structures

to serve public in community based research

• Target organizations that serve at risk

populations to reduce health disparities

Baltimore City Head Start Partnership

• 11 Head Start

Programs

• Over 50 sites
• 500 Staff members

– 100 FSC – 400 Teachers

• 3500 Children

Baltimore City Head Start

• 25-30% of children diagnosis
• f asthma
• 25-30% of children exposed

to secondhand smoke

• 95% African American
• 100% Low-income

Office of Head Start

In 2007 EPA and the Office of Head Start announced a Memorandum of Understanding

• Cooperative activities to promote awareness
• Distribute effective strategies
• Lacks support to implement

Efficacious Interventions to Reduce SHS exposure

• Systematic review has found behavioral

interventions to be most efficacious in reducing SHSe

• Motivational Interviewing

– 3 studies demonstrated efficacious – Not routinely implemented in community settings

Rosen 2012. Pediatrics; 129 :141 -152

Study Aims

• Evaluate the effectiveness of Motivational

Interviewing + Head Start education in reducing child SHSe compared to Head Start education alone

• Evaluate implementation of interventions

in Head Start using RE-AIM framework

RCT Design

• Families with 1+ smoker in the home recruited

from Head Start

• Assessments completed at Baseline, 3-, 6- ,

and 12- months – 2 home visits at each time point – Air nicotine monitoring for 7 days – 2 child salivary cotinine 7 days apart – Caregiver survey

• Randomized to MI + Education or Education

Alone after Baseline

Screening Procedures

• Screening survey disseminated by HS staff
• Option to not complete form but still be counted

– Have to opt-in to be contacted about the study

• HS Staff compensation

– $50 to teacher if 80% of class returns screener by due date – $50 to FSC if all assigned classrooms cumulatively meet 80% completion

Measures

• Air Nicotine
• Salivary Cotinine
• Prevalence of Home Smoking Bans

Head Start Education

• Smoke-free days
• Staff education
• Lesson plans
• Health Fairs
• Health Advisory Meetings

Implementation Strategies

• Offer CE credits
• Universal Screening
• Adapted Education program for each

HS site

• Website and resources available
• Awareness Building Activities
• Staff Engagement

Key Principles of Motivational Interviewing

• Develop Discrepancy
• Express Empathy
• Amplify Ambivalence
• Roll with Resistance
• Support Self Efficacy

Goal is to identify, examine and resolve ambivalence about change

MI + Education

• All components of Head Start Education
• 4 sessions of MI

– Provide feedback on cotinine – Decisional Balance – Motivation/confidence ladder – Training on talking to family members – Support self-efficacy – Smoking cessation, if applicable

Cotinine Feedback

High Exposure (above 4.5 ng/ml) Your child was exposed to as much smoke as if they were a smoker themselves. Moderate Exposure (between 2.0 and 4.5 ng/ml) Your child was exposed to moderate levels of smoke, as if they smoked a few cigarettes themselves. Low Exposure (between 0.05 and 2 ng/ml) Your child was exposed to low levels of cigarette smoke, but still much more than the child of a non- smoker. Very Low Exposure (less than 0.05 ng/ml) Your child had very low exposure to smoke. It is great that your child is kept away from smoke. Keep it up! No Exposure (0 ng/ml) Your child had no exposure to smoke. It is great that your child is kept away from smoke. Keep it up!

Effectiveness: Intent-To-Treat

• Overall ITT

– lower air nicotine at 12 months in MI + education group – Increase in prevalence of HSB at 3 months in MI + education group

• Post Hoc Analyses

– Families who implemented HSB had sig. lower cotinine and nicotine

Adoption: Head Start Staff Education

* p<0.05 for all items

Implementation: Community Based Research

• Staff witnessed a

homicide en route to a home visit

• Changed protocol

from home to phone intervention visits

Implementation: Home versus Phone

• 83 families were randomized to receive 2

home sessions and 3 phone sessions

• 82 families received 5 phone sessions
• Families in the phone only condition had

significantly lower air nicotine and greater prevalence of HSB at 3- and 12- months

• The phone only group had a significantly

higher completion rate (54% to 33%)

Maintenance

• 0 Head Start Programs have scheduled

SHS education program

• 29% of children still live with smokers
• 80% of families report having a home

smoking ban

– Increased from 70% at baseline

Intervention Evaluation using RE-AIM Framework

Outcome REACH 12% enrolled in study among all children with SHS; EFFECTIVENESS Families in the MI+ Educ group had a 15% increase in HSB and decrease in air-nicotine at 12 months and families with HSB had lower nicotine and cotinine ADOPTION 83% of HS programs participated in SHS training. Staff reported significant improvement in knowledge, beliefs and comfort talking about SHS. IMPLEMENTATION Only 33% completed 4 sessions Change in home vs. phone showed phone delivery had better completion rate and treatment effect Fidelity monitoring 2-3X/month MAINTENANCE 0 Head Start sites scheduled education programs after intervention period

Challenges to Implementation

• Limited community resources

– Time – Money – Staff

• Low uptake of intervention
• Competing demands on family

Qualitative Analyses of Unique Barriers for Intervention

• Transcribed random sample of 50

intervention session tapes

• 2 coders analyzed transcripts to identify

major themes using Grounded Theory Approach

• Identify barriers and facilitators for

implementing a home smoking ban

Barriers to SHS reduction

Child follows parent

• “it's like a moth to a flame, as soon as I light a cigarette he will come

flying in the room.”

Neighborhood Safety

• “They don't bother you too much, but I just don't like to see all what's

going on out there. I just don't like it.”

• “They selling out the house, they do all kinds of stuff over there.”

Police Involvement

• “Cause I see the police come walk their beat, ask questions, I don't

want to get involved so I just basically stay in the house.”

• “If the police see a lot of people in the front, then they bothering us.”

Weather

• “Cuz it's getting colder so probably more smoking we will do in the

house because of the weather.”

Facilitators of SHS Reduction

Physician Support

• “And then my doctor's talking to me about it.”
• “She was telling me, to just try to take it slow, don't try to do cold turkey

like I've been doing in the past.”

• “Cause my doctor put me on the patch. I couldn't do this without it.”

Cost

• “I don't care how stressed out I be, plus it cost too much.”
• “The money that I spend, I can spend on something else.”

Be a Good Parent

• “He feel like he did a great step, he took a great step for his family.”
• “Cause I feel like I failed as a parent with my first son because now I

see by me smoking so many years he picked up the habit and I'm trying to avoid that for the other 3.”

Tailor Interventions for Population

• Difficult for a caregiver to leave a young

child to smoke outside

• Inner city outdoor environments are

challenging

– Police harassment – Physical safety – Annoyance from neighbors (chipping)

• Family Dynamics

Implications

• MI is effective in reducing SHSe in Head start

children

• Need to develop different strategies to engage

more families

• Reduction to SHS exposure needs to be

addressed across multiple levels to increase reach and overall public health

• Need to develop mechanism for sustaining

interventions
