Background: The association between marital status and health status among the elderly has been at the forefront of investigation for a long time. However, the study on the effects of marital status on health care utilisation is limited. This study assesses the association between use of inpatient health services and marital status among older adults in India from the perspective of sex. Methods: Data used in the study have been obtained from the 75th Round of National Sample Survey (NSS) on "Social Consumption: Health" with the sample size of 42,762 individuals aged 60 years or above. The study implements the Andersen's behavioural framework controlling the predisposing, enabling, and need characteristics and uses binary logistic regression models to assess the effect of marital status on inpatient health service. Results: There is a significant difference in inpatient healthcare use between married and widowed elderly by age, educational level, perceived health and mobility for both sexes. The unadjusted regression analysis shows that widowed are more likely to use inpatient health services both for women (OR=1.57; CI 95%= 1.47, 1.68) and men (OR=1.11; CI 95%= 1.02, 1.2). However, after controlling the predisposing, enabling, and need factors, a strong association between healthcare services and marital status has been found for women, but not for men. Widowed women (OR=1.43; CI 95%=1.33, 1.54) are more likely to use inpatient health care than married women. Conclusion: The present study has reported the association between the utilisation of inpatient health services and marital status for the elderly in India. Our study advocates that there is a sex difference in the utilisation of inpatient health services by the marital Status in India. Older widowed women should get more focus on health and elderly policy perspectives.
