Making Research Matter


  • Racial and ethnic minorities are not likely to be enrolled in research
    - Despite demonstrated willingness to participate
  • Where does the disconnect between community member desire for research participation and actual research participation come from?


  • Substantial discordance between community member health conditions/concerns and topics of available studies for them to participate in (see figure in next slide)


  • The health conditions and health concerns of the community provide a wide range of public health relevant topics
  • Faculty research interests may not be aligned with community needs

*Health Concern percentages calculated out of the number of HealthStreet   members who provided at least one health concern as of March 2016 (n=6,724);

 Health Condition percentages calculated out of the total HealthStreet   member population with completed Health Intake Forms as of March 2016 (n=7,354);

Research Study topic percentages calculated out of all openly recruiting health research studies available to HealthStreet   members as of March 2016 (n=90)




  • Our project complements new statewide AD efforts with UF, Mount Sinai Medical Center, Memory Disorder Clinics, and other institutions to give Floridians an unprecedented opportunity to be part of cutting-edge AD screening, treatment and research.
  • We will develop a Florida AD Registry for early screening of underrepresented older adults in the community. The registry, protected with a Data Trust, would facilitate linkage between community members and the research enterprise to detect mild cognitive impairment (MCI) through diagnostic and therapeutic initiatives.
  • The project will launch an innovative, statewide community focused outreach program for underrepresented, diverse populations from three regions with the highest AD mortality.
  • Through Community Health Workers, 3,600 older adults will be assessed for MCI, social determinants, medical history, perceptions of and trust in AD research, and family history of AD.
  • We will link 360 65+ year olds with MCI in the new Florida AD Registry to research across Florida and eventually to a national patient powered network for AD.
  • With ongoing person-centered contact, and an expert team, we will track our efforts to increase AD knowledge, trust in research, recruitment, enrollment and retention in AD research that improves health.

Saturation Map of HealthStreet


Neighborhood Deprivation Index (NDI)

NDI was generated based on block group-level SES Indicators from the 2010-2014 American Community Survey:

  • Poverty: % HHs in poverty, % HHs earning <$30,000/year, % HHs with no vehicle
  • Occupation: % males(females) in management or professional occupations
  • Housing: % rented housing, % vacant housing, % renter/owner costs>50% income, median home values
  • Employment: % unemployed, % males no longer in work force
  • Education: % <high school education
  • Racial composition: % non-Hispanic blacks
  • Residential stability: % in same residence in the last year, % residents ≥65 years old

74% HealthStreet   participants are from areas with high deprivation*

HealthStreet   Frequent ED Utilizers

  • Characterized as ≥ 2 visits in the past 6-months 
  • Super-utilization is generally associated with:
    - Age- young adults and seniors
    - Females
    - Racial/ethnic minorities
    - Lower rates of employment
    - Higher rates of poverty
    - Less education
    - Medicare or Medicaid coverage
  • Between 4.6 to 8.0% of ED users are super-utilizers
    - These individuals account for between 21 to 28% of all visits
  • After controlling for age and gender, men with 3 – 5 chronic diseases had 6.33 AOR and women with 3 – 5 chronic diseases 3.49 AOR as those with no chronic diseases.  Significant AORs remained after adjusting for age, gender, depression, marital status, employment status and food insecurity (4.98 AOR and 2.49 AOR respectively)
