Examining the Association of Pain and Pain Frequency With Self-Reported Difficulty in Activities of Daily Living and Instrumental Activities of Daily Living Among Community-Dwelling Older Adults: Findings From the Longitudinal Aging Study in India

Abstract

OBJECTIVES: We examined the prevalence and associations of self-reported difficulty in activities of daily living (ADL) and instrumental activities of daily living (IADL) with pain among community-dwelling older adults in India. We also explored the interaction effects of age and sex in these associations. METHODS: We used the Longitudinal Ageing Study in India (LASI) Wave 1 data (2017-2018). Our unweighted sample included 31,464 older adults aged 60 years and above. Outcome measures were having difficulty in at least 1 ADL/IADL. We conducted multivariable logistic regression analyses to examine the association of pain with functional difficulties controlling for selected variables. RESULTS: A total of 23.8% of older adults reported ADL and 48.4% reported IADL difficulty. Among older adults who reported pain, 33.1% reported difficulty in ADL and 57.1% reported difficulty in IADL. The adjusted odds ratio (aOR) for ADL was 1.83 (confidence interval [CI]: 1.70-1.96) and for IADL was 1.43 (CI: 1.35-1.51) when respondents reported pain compared with those without pain. Older adults who reported frequent pain had 2.28 and 1.67 times higher odds of ADL (aOR: 2.28; CI: 2.07-2.50) and IADL difficulty (aOR: 1.67; CI: 1.53-1.82) compared with those with no pain. Additionally, age and sex of the respondents significantly moderated the associations of pain and difficulty in ADL and IADL. DISCUSSION: Given the higher prevalence and likelihood of functional difficulties among older Indian adults who experienced frequent pain, interventions to mitigate pain in this vulnerable population are needed to ensure active and healthy aging.
