  • Does home-based screening improve hypertension diagnosis, treatment and control? A regression discontinuity analysis in urban India

    Open AccessMichaela Theilmann, Sneha Sarah Mani et al.ARTICLEBMJ Global Health2025

    As part of India’s efforts to expand primary healthcare services, several state governments are implementing or considering home-based hypertension screening programmes to improve population-wide diagnosis and blood pressure (BP) control rates. However, there is limited evidence on the effectiveness of home-based screening programmes in India. Using six waves of population-representative cohort data (N=15574), we estimate the causal effect of a h…

  • Co-creating community engagement and involvement strategies

    Open AccessMonika Arora, Mansi Chopra et al.ARTICLEBMJ Global Health2025

    Living with multiple long-term conditions (MLTCs) presents significant healthcare and patient-level challenges, which are further compounded by fragmented and poorly coordinated healthcare systems, leading to difficulties in access, dissatisfaction with quality of services, non-engagement with treatment protocols and poor outcomes.

  • The role of neighborhood and household level socio-economic status in determining air pollution exposure in two Indian cities

    Open AccessJyothi S Menon, Siddhartha Mandal et al.ARTICLEEnvironmental Research Letters2025

    Although recent studies indicate that air pollution exposure affects lower socioeconomic groups more, there is limited evidence regarding the relative influence of household and neighborhood socioeconomic status (SES) on air pollution exposure in lower- and middle-income country settings. We evaluated the associations between neighborhood- and household-level SES metrics and exposure to ambient particulate matter (PM 2.5 ) in two populous Indian …

  • The maternal and newborn health eCohort to track longitudinal care quality

    Open AccessCatherine Arsenault, Katherine Wright et al.ARTICLEGlobal Health Action2024

    The MNH eCohort was developed to fill gaps in maternal and newborn health (MNH) care quality measurement. In this paper, we describe the survey development process, recruitment strategy, data collection procedures, survey content and plans for analysis of the data generated by the study. We also compare the survey content to that of existing multi-country tools on MNH care quality. The eCohort is a longitudinal mixed-mode (in-person and phone) su…

  • Methods and participant characteristics in the Cancer Risk in Vegetarians Consortium

    Open AccessYashvee Dunneram, Jia Yi Lee et al.ARTICLEBMC Public Health2024

    Food intakes and lifestyle factors of both non-vegetarians and vegetarians varied markedly across the individual cohorts, which may be due to differences in both culture and socioeconomic status, as well as differences in questionnaire design. Therefore, care is needed in the interpretation of the impacts of vegetarian diets on cancer risk

  • Doubling Farmers’ Incomes in India by 2022

    Open AccessSukhwinder Singh, Nikhil Srinivasapura Venkateshmurthy et al.ARTICLEMillennial Asia2024References: 1

    In 2016–2017, Indian government set a policy target of doubling farmers’ incomes by 2022. This article investigates farmers’ perspectives on this contentious policy. Results suggest that only 18% of farmers were aware of this policy. Most farmers blamed the government’s support, high cost of cultivation and low MSP for their inability to increase their farm profitability. While synthesizing farmers’ perspectives, past trends, and the debate among…

  • Effect modification by sex for associations of fine particulate matter (PM 2.5 ) with cardiovascular mortality, hospitalization, and emergency room visits

    Open AccessSeongkum Heo, Ji-Young Son et al.ARTICLEEnvironmental Research Letters2022

    Particulate matter with aerodynamic diameter no larger than 2.5 μm (PM 2.5 ) has been linked to cardiovascular diseases (CVDs) but evidence for vulnerability by sex remains unclear. We performed systematic review and meta-analysis to synthesize the state of scientific evidence on whether cardiovascular risks from PM 2.5 differ for men compared to women. The databases Pubmed, Scopus, Embase, and GreenFILE were searched for studies published Jan. 1…

  • Anxiety and depression among adult tobacco users during the Covid-19 restrictions in India

    Open AccessShalini Bassi, Gaurang P Nazar et al.ARTICLEFrontiers in Psychiatry2022

    During COVID-19 lockdown, mental health of tobacco users (primarily women) was associated with food, housing and financial insecurity.
