Assessing multilevel association of genderism on cognitive health of older adults across mesosystems and microsystems using the longitudinal aging study in India: An adaptation of the ecological syste…
Structural and social determinants across chronosystems critically shape educational transitions and cognitive aging in India by influencing cognitive reserve through life-course. Drawing on Bronfenbrenner's Ecological Systems Theory and the Cumulative Disadvantage/Advantage frameworks, we conceptualize genderism as a structural and social determinant of cognitive health operating across multiple ecological levels - national (macrosystem), region…

The results reveal marked structural changes in the age patterns of morbidity and mortality. The analysis also tested whether morbidity contour…
Understanding epidemiological transition in India
BACKGROUND: Omran's theory explains changing disease patterns over time predominantly from infectious to chronic noncommunicable diseases (NCDs). India's epidemiological transition is characterized by dual burden of diseases. Kumar addressed low mortality and high morbidity in Kerala, which seems also to be true for India as a country in the current demographic scenario. METHODS: NSS data (1986-1987, 1995-1996, 2004) and aggregated data on causes…
Maternal and child mortality indicators across 187 countries of the world: Converging or diverging
This study reassessed the progress achieved since 1990 in maternal and child mortality indicators to test whether the progress is converging or diverging across countries worldwide. The convergence process is examined using standard parametric and non-parametric econometric models of convergence. The results of absolute convergence estimates reveal that progress in maternal and child mortality indicators is diverging for the entire period of 1990…
Relevance of Health Knowledge in Reporting Maternal Health Complications and Use of Maternal Health Care in India
We measured levels of women's health knowledge and their association with the reporting of maternal health complications and related health care use. We found that women with higher levels of health knowledge reported more pregnancy and postnatal complications, and used more maternal health care services. Education has a positive impact on health, but education alone is not enough to ensure recognizing and reporting of health complications and in…
The impact of multimorbidity on adult physical and mental health in low- and middle-income countries: What does the study on global ageing and adult health (Sage) reveal?
BACKGROUND: Chronic diseases contribute a large share of disease burden in low- and middle-income countries (LMICs). Chronic diseases have a tendency to occur simultaneously and where there are two or more such conditions, this is termed as 'multimorbidity'. Multimorbidity is associated with adverse health outcomes, but limited research has been undertaken in LMICs. Therefore, this study examines the prevalence and correlates of multimorbidity as…
