Insights
Unmet social needs and scarcity impact medication adherence in children with asthma. Addressing these social determinants may improve asthma control for vulnerable youth.
Area of Science:
- Pediatric Asthma Management
- Social Determinants of Health
- Behavioral Economics in Healthcare
Background:
- Asthma is a prevalent childhood chronic disease, disproportionately affecting lower socioeconomic status children.
- Suboptimal adherence to controller medications is a key factor in poor asthma control.
- Unmet social needs (food, lodging, childcare) create parental stress, impacting medication adherence.
Purpose of the Study:
- Investigate the relationship between unmet social needs, scarcity, and future discounting on pediatric asthma medication adherence.
- Assess the predictive power of these factors over time.
- Identify potential targets for integrated social care interventions.
Main Methods:
- 12-month prospective observational cohort study of 200 families with children aged 2-17 years.
- Primary outcome: adherence to controller medication (proportion of prescribed days covered).
- Key independent variables: unmet social needs, scarcity, future discounting (measured at recruitment and 6, 12-month follow-ups).
Main Results:
- Study enrollment and data collection began August 2022 and are ongoing until September 2024.
- Analysis will compare medication adherence between families with and without unmet social needs.
- Exploratory outcomes include healthcare utilization.
Conclusions:
- This study will document the impact of social needs, scarcity, and future discounting on asthma medication adherence in children.
- Findings may support novel, integrated social care interventions to improve adherence and reduce health risks.
- Potential to improve long-term outcomes for vulnerable children with asthma.
Background:
Asthma is one of the most prevalent chronic diseases of childhood and disproportionately affects children with lower socioeconomic status. Controller medications such as inhaled corticosteroids significantly reduce asthma exacerbations and improve symptoms. However, a large proportion of children still have poor asthma control, in part owing to suboptimal adherence. Financial barriers contribute to hindering adherence, as do behavioral factors related to low income. For example, unmet social needs for food, lodging, and childcare may create stress and worry in parents, negatively influencing medication adherence. These needs are also cognitively taxing and force families to focus on immediate needs, leading to scarcity and heightening future discounting; thus, there is the tendency to attribute greater value to the present than to the future in making decisions.
Objective:
In this project, we will investigate the relationship between unmet social needs, scarcity, and future discounting as well as their predictive power over time on medication adherence in children with asthma.
Methods:
This 12-month prospective observational cohort study will recruit 200 families of children aged 2 to 17 years at the Asthma Clinic of the Centre Hospitalier Universitaire Sainte-Justine, a tertiary care pediatric hospital in Montreal, Canada. The primary outcome will be adherence to controller medication, measured using the proportion of prescribed days covered during follow-up. Exploratory outcomes will include health care use. The main independent variables will be unmet social needs, scarcity, and future discounting, measured using validated instruments. These variables will be measured at recruitment as well as at 6- and 12-month follow-ups. Covariates will include sociodemographics, disease and treatment characteristics, and parental stress. Primary analysis will compare adherence to controller medication, measured using the proportion of prescribed days covered, between families with versus those without unmet social needs during the study period using multivariate linear regression.
Results:
The research activities of this study began in December 2021. Participant enrollment and data collection began in August 2022 and are expected to continue until September 2024.
Conclusions:
This project will allow the documentation of the impact of unmet social needs, scarcity, and future discounting on adherence in children with asthma using robust metrics of adherence and validated measures of scarcity and future discounting. If the relationship between unmet social needs, behavioral factors, and adherence is supported by our findings, this will suggest the potential for novel targets for integrated social care interventions to improve adherence to controller medication and reduce risk across the life course for vulnerable children with asthma.
