Background
Health Literacy (HL)“the degree to which individuals have
the capacity to obtain, process, and understand basic health
information and services needed to make appropriate health decisions”
DHHS, 20003
![Page 4: Exploring the Association between Maternal Health Literacy and Pediatric Healthcare Utilization](https://reader035.vdocuments.us/reader035/viewer/2022070304/54bd60be4a7959e0128b4608/html5/thumbnails/4.jpg)
Background
We know
Women with low health literacy have poor health outcomes and underutilize preventive care

Background
We know
Appropriate use of pediatric preventive care is associated with significant reductions in morbidity and mortality and has been shown to reduce healthcare costs and decrease hospital admissions

Significance
• We don’t know– Are children of mothers with low health
literacy at a disadvantage similar to that of their mothers?
• Conflicting evidence about the impact of maternal HL on pediatric social and health outcomes – Pati et al (2011) -TANF/Vaccination compliance

Parent Study
• Community based prospective cohort study of mothers and infants in Philadelphia– Investigating the contextual, social, behavioral,
and family context of maternal child health (extensive surveys)
– Followed from prenatal period to 24 months post partum
– >5000 participants – 1034 had health literacy assessments – REALM / STOFHLA
• Funded by the CDC and National Institute of Child Health and Development 8
CDC (TS 312 15/15; Culhane) and NICHD (1R01 D36462 01A; Elo and Culhane)

Operationalized Independent Variables
Predisposing
Enabling
Need
9
Demographic characteristics, such as race, age, and
maternal education have been shown to impact parent
driven pediatric health service useHere Andersen grouped
personal and family factors including social supports,
income, insurance & physical access to providers
Need, the strongest predictor of health service use based
on how people view their own functional capacity,
symptoms, & general state of health
(and that of the children they care for)

Dependent Variables Operationalized
Well- Child Visits Year 1 /Year 2
(WCV)
10
The primary outcome measure of preventive care utilization is the overall number of documented well-child visits in the first two years of lifeThe AAP recommends 7 WCV in year 1 of life and 3 in year 2 of life
ED. SCV, % Compliance
CPT and ICD-9 Codes were used to identify these visits in the Medicaid claims files AAP, 2011
ED Visits Year 1 /Year 2

Quantitative Analysis Revealed
• HL was not associated with the number of well-child visits, sick-child visits, ED visits or % compliance with a minimum number of visits in year 1 and year 2 of life
• HL did not prove to mediate or moderate the relationships between any of predisposing and enabling factors under study and our outcomes of interest
• Higher health literacy was not protective in this population

Qualitative Analysis Revealed
• Women with low HL and women higher HL encountered an overlapping set of challenges when navigating the healthcare system
• Several themes emerged and were used to elaborate on Andersen’s Model and shed light on the quantitative findings and a critical case emerged

A Critical Case Emerges Back ground and significance:
•Dyslexia affects 5-17% of adults in the US•No significant difference in the prevalence across socioeconomic strata•Undiagnosed dyslexia, is more common among the poor
Methods: •Four in depth interviews•Participant graduated from high school and had attended community college •Diagnosed with severe dyslexia (mid 20s) had no intervention.
Results: •Poor readers with dyslexia may be difficult to identify•Strategies used to compensate for LD may render common HL screening tools ineffective •REALM did not identify this participant
Conclusions and Implications: •Strategies employed by persons w/ LD may fail in the healthcare setting•Strategies are not well suited for HC where anxiety is high and accuracy is crucial•HL interventions may not be effective in the context of dyslexia or other learning disabilities

Missed Opportunities
“Yes, but I, but I’m like, OK, it prevents cancer, is there any side effects from
it, he’s like no, no, it’s in the pamphlet and I’m like, I see that, I
understand that, I understand it was on paper, but it’s different when you
hear it from someone. And I just wish he would’ve had more of a
conversation about it, ‘cause it was like, no, I, everybody’s getting it, and
I’m like OK?” Note:
This participant declined the HPV vaccine for her daughter, who she generally relies on to translate written materials.

Benefit of Mix Methods
• New Concepts – Lay informants – Pseudo experts– Experts
• Confirmation – Parity – Employment
• Unexpected findings (dyslexia example)
“I don’t take advice from
family or friends as much as I would a doctor”
“I would call
the
hospital…... I
got
reprimanded
for calling”“My cousin is
in nursing school”
“Friends, but
their kids are
younger so
they don’t
know”

Dependent Variables Operationalized
Compliant Year 1(WCV)
Compliant Year 2(WCV)
Shulmen, 200631
We also documented the percent of dyads that were compliant with a minimum number of WCV per year
There is a precedent in the literature for setting this bench-mark at 4 for year 1 and 2 for year 2 of life, slightly lower than the AAP recommendations
CPT and ICD-9 Codes were used to identify these visits in the Medicaid claims files

Hypotheses
Mothers with low health literacy (< 6th grade) will be less likely than mothers with marginal to higher health literacy (> 7th grade) to meet pediatric preventive care recommendations.

Hypotheses
Children of mothers with low health literacy (< 6th grade) will be more likely than children of mothers with marginal to high health literacy (> 7th grade) to
•visit an emergency room.
•be seen by a provider for a sick-child visit.

Hypotheses
Low maternal health literacy will mediate the relationship between negative predisposing and enabling factors and
•timely receipt of pediatric preventive care.
•pediatric emergency room visits.
•the number of sick-child visits.34

Hypotheses
Low maternal health literacy will moderate the relationship between negative predisposing and enabling factors and
•timely receipt of pediatric preventive care.
•pediatric emergency room visits.

Qualitative Methods
• In depth semi structured interviews– Issues of interest
• Need factors / perceived need• Health beliefs• Social support/relationships• Ability to navigate the healthcare system
• Transcribed verbatim • Coded using NVIVO8 (QSR) software
guided by Andersen’s model

Guiding Qualitative Hypotheses
Qualitative interviews will show that mothers with low health literacy will
report different issues related to access to preventive pediatric care than mothers with marginal to high
health literacy.
Additionally, they will perceive different barriers to care and will suggest different interventions
to reduce these barriers.

Quantitative Analysis Revealed
• HL was not associated with the number of well-child visits, sick-child visits, ED visits or % compliance with a minimum number of visits in year 1 and year 2 of life
• When we controlled for health literacy we saw no impact on establish associations between a set of independent variables and our outcome variables

Associations of Interest
• 66% of the women in our sample had completed high school or GED however only 50% had a REALM score > 9th grade
• 100% of the women in the highest HL
group were born in the US while that was the case for only 80% of the women in the low HL group

Qualitative Analysis Revealed
• Women with low HL and women higher HL encountered an overlapping set of challenges when navigating the healthcare system
• Confirmed the quantitative findings (for the most part kids are getting the minimum number of visits)
• Several themes emerged and were used to elaborate on Andersen’s Model and shed light on the quantitative findings
• Critical case emerged 58

• Confirmation – Parity – Employment
• Unexpected findings (dyslexia example)

family or friends as much as I would a doctor”
“I would call

A Critical Case Emerges Back ground and significance:
•Dyslexia affects 5-17% of adults in the US•No significant difference in the prevalence across socioeconomic strata•Undiagnosed dyslexia, is more common among the poor
Methods: •Four in depth interviews•Participant graduated from high school and had attended community college •Diagnosed with severe dyslexia (mid 20s) had no intervention.
Results: •Poor readers with dyslexia may be difficult to identify•Strategies used to compensate for LD may render common HL screening tools ineffective •REALM did not identify this participant
Conclusions and Implications: •Strategies employed by persons w/ LD may fail in the healthcare setting•Strategies are not well suited for HC where anxiety is high and accuracy is crucial•HL interventions may not be effective in the context of dyslexia or other learning disabilities

Missed Opportunities
“Yes, but I, but I’m like, OK, it prevents cancer, is there any side effects from
it, he’s like no, no, it’s in the pamphlet and I’m like, I see that, I
understand that, I understand it was on paper, but it’s different when you
hear it from someone. And I just wish he would’ve had more of a
conversation about it, ‘cause it was like, no, I, everybody’s getting it, and
I’m like OK?” Note:
This participant declined the HPV vaccine for her daughter, who she generally relies on to translate written materials.

Health Literacy
• 50% of the group was compliant in year 1 and this did not vary by health literacy
• 44% of the group was compliant in year 2 and again no variation by health literacy
Does health literacy matter in this population?

Limitations & Lessons Learned
• Sample size / power• Inclusion criteria
– 10 month of eligibility
• Locating the poorest readers • REALM
– Was it reliable in the population? – Does it need to be validated in the context of
LD?
• Did not take full advantage of the
available data* • Limited generalizability and transferability 67
![Page 68: Exploring the Association between Maternal Health Literacy and Pediatric Healthcare Utilization](https://reader035.vdocuments.us/reader035/viewer/2022070304/54bd60be4a7959e0128b4608/html5/thumbnails/68.jpg)
Next Steps
• Augment the current analysis and submit a paper for publication – Abstract has been sent to APHA
• Critical Case was presented at Health Literacy Annual Research Conference – Need to further explore how a learning
disability impacts health literacy
68
![Page 69: Exploring the Association between Maternal Health Literacy and Pediatric Healthcare Utilization](https://reader035.vdocuments.us/reader035/viewer/2022070304/54bd60be4a7959e0128b4608/html5/thumbnails/69.jpg)
Next Steps Continued
• Now that the dyads have been established we plan to revisit the survey data in order to explore additional research questions (many of which were brought to light in the qualitative arm of the study)
• For example:– Feeling respected by a provider (qualitative)– Mastery Scale and Coping Questions (parent study)
• “Sometimes I feel that I am being pushed around in life” • “There is little I can do to change many of the important things in
life”
• For example:– Depression/mental illness (qualitative)– Depression (parent study)
