University of North Carolina at Chapel Hill
![Page 2: Using Historical Records to Reconstruct Early Life SES Exposures in Decedents: Preliminary Findings from a Pilot Study Kathryn Rose and J. Stephen Perhac.](https://reader035.fdocuments.in/reader035/viewer/2022072014/56649e7d5503460f94b7f74a/html5/thumbnails/2.jpg)
Background
• Early life socioeconomic conditions associated with increased risk of chronic diseases in adulthood
• In most ongoing epidemiologic studies early life SES not ascertained at study inception– Collect from study participants while study is
ongoing – Obtain from historical records
![Page 3: Using Historical Records to Reconstruct Early Life SES Exposures in Decedents: Preliminary Findings from a Pilot Study Kathryn Rose and J. Stephen Perhac.](https://reader035.fdocuments.in/reader035/viewer/2022072014/56649e7d5503460f94b7f74a/html5/thumbnails/3.jpg)
• Linkage of death certificates with 1900-1920 individual census records (Hill, 2000; Preston,1996)– Elderly, white men: 70% linkage– Elderly black men: 56% linkage
• Study of link between childhood SES and Alzheimer’s disease (Moceri, 2001)– Attempted linkage with birth certificates and
declassified 1910-20 census records• 86% of participants linked to birth certificates and/or
census record• No significant variation by gender, age or education
Can Early Life SES Be Obtained From Historical Records?
![Page 4: Using Historical Records to Reconstruct Early Life SES Exposures in Decedents: Preliminary Findings from a Pilot Study Kathryn Rose and J. Stephen Perhac.](https://reader035.fdocuments.in/reader035/viewer/2022072014/56649e7d5503460f94b7f74a/html5/thumbnails/4.jpg)
Rationale for Current Pilot Study
• Feasibility of using public records to obtain early life SES information:– Accessibility– Cost ($$$ and time)– Availability of parental SES data
• Completeness• Comparability to data from other sources
• What are the sociodemographic determinants of successful linkage?
![Page 5: Using Historical Records to Reconstruct Early Life SES Exposures in Decedents: Preliminary Findings from a Pilot Study Kathryn Rose and J. Stephen Perhac.](https://reader035.fdocuments.in/reader035/viewer/2022072014/56649e7d5503460f94b7f74a/html5/thumbnails/5.jpg)
Participants
• Atherosclerosis Risk in Communities (ARIC) Study – Baseline examination 1987-89– Participants born between 1922 and 1944
• 451 participants from NC field center who subsequently died – Born between 1922-1935 (N=334)– Born in NC (N=319)

• Available for > 99% of decedents
– Social Security application (SS-5) data• Obtained for 99% of decedents
• Information abstracted:– Mother and father’s names– Participant data:
• Name(s), date and place of birth, race, gender

NC Birth Certificate Search
• 269 of 321 (84%) requested records found– Yield of usable records lower
• (N=253 - 79%)
– Yield:• Higher for whites than blacks (81% vs. 72%)• Higher for men than women (81% vs. 76%)• Did not not vary by education
– 95% contained parental occupational data

Linkage with 1930 Census Records
• Accessed using a proprietary website with computerized index
• Criteria Used to determine match:– Place of birth match vs. census address– Match on both parents’ names – Match on race– If participant born at the time of census
• Did age and name match?

Linkage with 1930 Census Records
• 238 of 334 records (71%) found on initial searches– Yield:
• Higher for whites (74%) than blacks (57%) • Higher for men (73%) than women (68%)• Lower for those with less than HS education
(69%) than for those with 12+ years of education (72%)
• Highest between 1927 and 1931 (80% +)

Sociodemographic Information Available from 1930 Census Records
• Virtually complete and legible
• Socioeconomic information• Home ownership• Household size• Literacy of mother and father• Occupational data on parents
– Job title – Industry– Whether an owner or an employee– Current employment status

Strengths and Limitations: Birth Certificate Data
Strengths• Data collected
directly from parents at time participant was born
• Records archived by state
Limitations • Limited SES data• Variation in content
across time and place• Access rules vary by
state• During this time period
records not always filed at birth
• Costly
![Page 17: Using Historical Records to Reconstruct Early Life SES Exposures in Decedents: Preliminary Findings from a Pilot Study Kathryn Rose and J. Stephen Perhac.](https://reader035.fdocuments.in/reader035/viewer/2022072014/56649e7d5503460f94b7f74a/html5/thumbnails/17.jpg)
Strengths and Limitations: Census Data
Strengths• Data collected in a
standardized manner across U.S. by trained census takers
• Large amount of parental SES-related data
• Inexpensive• Every person is
indexed
Limitations • Records are hand-
written• Data abstraction is
tedious• Limited ability to
track those not born in close proximity to census
• Only declassified after 72 years
![Page 18: Using Historical Records to Reconstruct Early Life SES Exposures in Decedents: Preliminary Findings from a Pilot Study Kathryn Rose and J. Stephen Perhac.](https://reader035.fdocuments.in/reader035/viewer/2022072014/56649e7d5503460f94b7f74a/html5/thumbnails/18.jpg)
Next Steps
• Continued search of census records• Comparison of the parental occupational
data from different sources – Census vs. birth certificate
– 1920 vs. 1930 census
– Historical records vs. those reported by participants
![Page 19: Using Historical Records to Reconstruct Early Life SES Exposures in Decedents: Preliminary Findings from a Pilot Study Kathryn Rose and J. Stephen Perhac.](https://reader035.fdocuments.in/reader035/viewer/2022072014/56649e7d5503460f94b7f74a/html5/thumbnails/19.jpg)
Conclusions
• It is feasible to use birth certificates and early census records as a source of early life SES information– Accessible – Parental SES information is complete– Labor-intensive and potentially expensive
• Potential use in such data is missing due to loss to follow-up
