Sanchit Makkar, Jawahar Ramasamy Manivannan, Sumathi Swaminathan, Sandra M Travasso, Anjaly Teresa John, Patrick Webb, Anura V Kurpad, Tinku Thomas

Journal : BMJ Open Year : 2022 May

There are scant empirical data on the impacts of the COVID-19 pandemic on food security across the globe. India is no exception, with insights into the impacts of lockdown on food insecurity now emerging. We contribute to the empirical evidence on the prevalence of food insecurity in Bihar state before and after lockdown, and whether the government's policy of cash transfer moderated negative effects of food insecurity or not.   Read More

Modelling the potential impacts of improved monthly income on child stunting in India: a subnational geospatial perspective.

Satvik Kishore, Tinku Thomas, Harshal Sachdev, Anura V Kuruppad, Patrick Webb

Journal : BMJ Open Year : 2022 April

Approximately one-third of the world's stunted (low height-for-age) preschool-aged children live in India. The success of interventions designed to tackle stunting appears to vary by location and depth of poverty. We developed small-area estimation models to assess the potential impact of increments in household income on stunting across the country.   Read More

Antioxidant micronutrient supplements for adult critically ill patients: A bayesian multiple treatment comparisons meta-analysis.

Kiran Kumar Gudivada, Ashish Kumar, Krishnan Sriram, Jeswin Baby, Mariam Shariff, Sriram Sampath, Sumitra Sivakoti, BhuvanaKrishna

Journal : Clinical Nutrition ESPEN Year : 2022 February

Antioxidant micronutrients (AxMs) have been administered to critically ill adults attempting to counteract the oxidative stress imposed during critical illness. However, results are conflicting and relative effectiveness of AxMs regimens is unknown. We conducted a Bayesian multi-treatment comparison (MTC) meta-analysis to identify the best AxM treatment regimen that will improve clinical outcomes.   Read More

Revascularization or optimal medical therapy for stable ischemic heart disease: A Bayesian meta-analysis of contemporary trials.

Journal : Cardiovascular Revascularization Medicine Year : 2021 December

The role of revascularization in patients with stable ischemic heart disease (SIHD) has been controversial, more so in the present era of drug-eluting stents.To examine the absolute risk difference (ARD) between revascularization plus optimal medical therapy (OMT) versus OMT alone among patients with SIHD using Bayesian approach.   Read More

Blood Cultures and Molecular Diagnostics in Intensive Care Units to Diagnose Sepsis: A Bayesian Latent Class Model Analysis.

Sriram Sampath, Jeswin Baby, Bhuvana Krishna, Nandini Dendukuri, Tinku Thomas

Journal : Indian Journal of Critical Care Medicine Year : 2021 December

Confirmation of sepsis by standard blood cultures (STD) is often inconclusive due to slow growth and low positivity. Molecular diagnostics (MOL) are faster and may have higher positivity, but test performance can be inaccurately estimated if STD methods are used as comparators. Bayesian latent class models (LCMs) can evaluate diagnostic methods when there is no “gold standard.” Intensive care unit studies that have used LCMs to combine and compare ...   Read More

Contribution of economic and nutritional context to overweight / obesity dynamics in Indian women from 1998 to 2016: a multilevel analysis of national survey data.

Jeswin Baby, Jithin Sam Varghese, Shruthi Cyriac, M Venkat Narayan, Anura V Kurpad, Tinku Thomas, Shivani Patel

Journal : BMJ Open Year : 2021 December

Overweight/obesity increased dramatically among Indian women since 2000. We evaluated the independent contributions of economic and nutrition context to the changing distribution of overweight/obesity among women from 1998 to 2016 across India. Individual-level data from 473912 ever married Indian women aged 18-49 in the National Family Health Surveys (1998-1999, 2005-2006, 2015-2016) were merged with year-matched state-level economic and nutrition...   Read More

Re-evaluating the need for universal iron supplementation in pregnant Indian women in the light of gestational age specific low hemoglobin prevalence.

Aswathi Saji, Jeswin Baby, Anura V Kurpad, Tinku Thomas

Journal: I J C H Year : 2021 September

Anemia prevalence among Indian pregnant women in 2015-16 was 50.4% and has not declined from 49.7% in 1998-99 despite the national policies on iron-folic acid supplementation. New gestational age-specific cut-offs (INTERGROWTH cut-off) for risk of low Hemoglobin (Hb) have been identified. Aims and objectives: Compare prevalences of low Hb based on WHO and INTERGROWTH cut-offs Methods: The prevalence of anemia/low Hb among pregnant women in trimesters 2 and 3 from NFHS-4 data were estimated using the current WHO recommendations and the INTERGROWTH cut-offs.   Read More

Factors influencing household pulse consumption in India: A multilevel model analysis.

Anjaly Teresa John, Sanchit Makkar, Sumathi Swaminathan, Sumedha Minocha, Patrick Webb, Anura V Kurpad, TinkuThomas

Journal : Global Food Security Year : 2021 April

Pulses (also known as legumes) are important in achieving nutrient adequacy in India due to their quality protein content. This study compared district-level pulse production and consumption across India, and household and district-level determinants of pulse intake, including availability, accessibility and affordability, using multi-level models in nationally representative datasets for 2011-12. The per capita consumption was about 50% of recommended intake (80 g/day), even in high-producing districts. District-level pulse production was associated with household pulse intake...   Read More

Dietary Iron Intake and Anemia Are Weakly Associated, Limiting Effective Iron Fortification Strategies in India.

Sumathi Swaminathan, Santu Ghosh, Jithin Sam Varghese, Harshpal S Sachdev, Anura V Kurpad, Tinku Thomas

Journal : The Journal of Nutrition Year : 2019 May

Anemia prevalence in India remains high despite preventive iron supplementation programs. Consequently, concurrent national policies of iron fortification of staple foods have been initiated.This study evaluated the relation between dietary iron intake and anemia (hemoglobin < 12 g/dL) in women of reproductive age (WRA; 15-49 y) with respect to iron fortification in India.   Read More

Demand and supply factors of iron-folic acid supplementation and its association with anaemia in North Indian pregnant women.

Jithin Sam Varghese, Sumathi Swaminathan, V Kurpad, Tinku Thomas

Journal : PLOS ONE Year : 2019 January

Anaemia prevalence in pregnant women of India declined from 57.9% to 50.3% from National Family Health Survey (NFHS)-3 to NFHS-4. However, over the course of that decade, the uptake of iron and folic acid (IFA) supplementation for 100 days of pregnancy improved by only 15%. To understand demand side risk factors of anaemia specifically related to IFA intake, an in-depth survey was conducted on pregnant women (n = 436) in 50 villages and wards of Sirohi district of Rajasthan...   Read More
