Harmonized Data from Six Ageing Cohorts on Multisite Pain and IADL Impairment

Harmonized individual-level data from six longitudinal ageing cohorts supports the study "Multisite pain, pain severity and incident instrumental activities of daily living impairment in middle-aged and older adults". The dataset includes measures of multisite pain, incident IADL impairment, and covariates like age, sex, and socioeconomic status.

Use Cases

• Analyze the association between pain severity and functional decline based on pain severity measures.
• Model the risk of IADL impairment based on the number of pain sites.
• Investigate the role of covariates like socioeconomic status and comorbidities in pain-related outcomes.
• Replicate findings from the original study on multisite pain and incident IADL impairment.

Strengths

• Harmonized data from six distinct longitudinal ageing cohorts provides a multi-source perspective.
• The dataset includes key covariates such as socioeconomic status and lifestyle factors, enabling controlled analyses.
• The 24.3 MB file size suggests a dataset with substantial individual-level records.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale modeling.
• Data may reflect geographic or temporal bias inherent to the specific cohort studies aggregated.
