Interdisciplinary research training : NCD epidemiology and prevention in India
The interdisciplinary research training program on non-communicable diseases (NCDs) focuses on the epidemiology and prevention of NCDs across the life-course, in cross-connecting subject areas (child health, nutrition and lifestyle, environmental health, obesity and diabetes, stroke and other vascular diseases) and population science disciplines (epidemiology and biostatistics, clinical trials, translation research, social sciences, and economics). The aim of this project is to provide short-term training in year one where eight junior faculty researchers will receive four months of training at Emory to acquire specific and focused mentoring and research skills. A total of ten post-doctoral fellows (one batch of five in years 2-3 and one batch in years 4-5) will receive 24 months of training (four months at Emory in the first year, six weeks at Emory in the second year, and the remaining 18.5 months in India).
Prevention of type 2 diabetes in women with gestational diabetes in urban India – a feasibility study:
Gestational diabetes (GDM) is a strong risk factor for developing type 2 diabetes mellitus. GDM and type 2 diabetes are both common among Indian women. Limited information about lifestyle programs to prevent or delay diabetes in women with GDM is available from other countries, but their applicability in India is unknown. We are evaluating the feasibility of adapting such programs by making them culturally appropriate to the Indian context and testing them in a small group of patients. The study is being carried out at All India Institute of Medical Sciences and the Centre for Fertility Management, Hyderabad with the aim of recruiting a total of 250 pregnant women with gestational diabetes. The results from this study will allow us to refine the program and perform a larger study to conclusively determine its generalizability and sustainability in urban India.

The CARRS – Surveillance Study:
CCDC, the scientific and executive secretariat of the Center of Excellence in Cardio-metabolic Risk Reduction in South Asia (CoE-CARRS) in PHFI, is implementing a cohort modeled cardio metabolic surveillance study in three major cities in South Asia (Chennai, Delhi and Karachi). The study partners are PHFI, Emory University, AIIMS, Aga Khan University Karachi and Madras Diabetic Research Foundation, Chennai. The CARRS Surveillance study starts with a baseline cross-sectional survey enrolling 12,000 participants and following them over a period of three years to collect preliminary incidence, morbidity, and mortality data.
CARRS – Sub-Studies
1. Assessment of dietary salt intake levels among adults in Delhi and Haryana: Multiple epidemiological studies conducted worldwide have found excess dietary salt or sodium intake to be associated with increased risk of high blood pressure or hypertension. Also nearly half of blood pressure related CVD events occur among those without clinical hypertension, so population wide salt reduction is clearly one of the most cost-effective strategies to prevent CVD. This sub-study of CARRS Surveillance Study and the ICMR Urban-Rural Study seeks to provide contemporary data on salt consumption levels and sources of dietary salt in Delhi and Haryana, which will reflect recent dietary changes that are occurring in India.
The three main objectives are:
1) to determine the mean daily salt consumption through the collection of 24- hour urinary sodium excretion samples
2) to determine the main sources of salt in the diets using 24-hour dietary recall method and
3) to assess knowledge, attitudes and behaviors with regard to salt consumption and its impact on health by a questionnaire. The total duration of the proposed project is two years and survey will include 1400 participants with roughly half each residing in urban Delhi and rural Haryana.

2. Prevalence of Polycystic ovarian syndrome (PCOS) and its association with cardiometabolic risk factors in reproductive age women in Delhi and Chennai, India: Women with PCOS are more likely to have increased cardiometabolic risk factors. The prevalence of PCOS in India and its association with cardiometabolic risk factors have not been studied extensively. The objective of this study was to measure the prevalence of oligomenorrhea and self-reported hirsutism as markers of PCOS in a representative sample of reproductive age women in Delhi and Chennai in the CARRS (Centre for Cardiometabolic Risk Reduction) cohort. CARRS is a multi-stage cluster random sampling cross sectional survey of adults aged >20 years (non-pregnant women) to measure prevalence of cardiometabolic risk factors in South Asia. Female participants of reproductive age received an additional validated PCOS questionnaire. Our definition of PCOS is limited to oligomenorrhea and clinical features of hyperandrogenism.
To assess for oligomenorrhea, participants were asked:
1) How many menstrual cycle have you had?
2) How long was the longest menstrual cycle in the last year? (after excluding for breast feeding, menopause and hysterectomy). To assess hirsutism, women were asked to score themselves using pictures of the 9 body parts used to calculate the modified Ferriman-Gallway score.
The preliminary results from this study were presented at the American Diabetes Association Conference, San Francisco, 2014. In summary, PCOS questionnaire was administered to 1927 female participants in Delhi and Chennai. The prevalence of oligomenorrhea and hirsutism was 11.6% and 6.6%, respectively. The prevalence of oligomenorrhea and self-reported hirsutism was higher in South Asian women compared to other ethnicities. This may have implications for future cardiovascular risk in the population studied.

Simplified Cardiovascular Management Study (SIMCARD): The simplified cardiovascular management program, also known as the SimCard study, was a one-year cluster-randomized controlled trial carried out in 47 villages in Haryana, India and Tibet, China and with limited access to basic cardiovascular disease (CVD) management and appropriate medications. The study was carried out by the Public Health Foundation of India (PHFI) in collaboration with the Centre for Chronic Disease Control (CCDC), All India Institute of Medical Sciences (AIIMS) in India and The George Institute for Global Health at Peking University Health Science Center in collaboration with Tibet University in China.
The study enrolled 2086 individuals with high CVD risks, defined as over 40 years old with a self-reported history of CVD and a measured systolic blood pressure over 160mmHg. Community health workers (CHWs) were deployed and trained to manage those individuals with the assistance of an Android smartphone app consisting of a guideline-based but simplified CVD management program.
A simplified ‘2+2’ intervention model, which consisted of two medications (blood pressure lowering agents and aspirin) and two lifestyle modifications (smoking cessation and salt reduction), was developed. The model was based on the international and national clinical guidelines for CVD management so that it can be easily implemented and incorporated into the existing local healthcare system as well. In both China and India, interventions were tailored to the local cultures and customs when possible. For example, Health educational materials on lifestyle in China and India were all provided in local languages with cultural-specific images.
The combined results strongly demonstrated the effectiveness of the SIMCARD trial in increasing the adherence to anti-hypertensive medications, (a net-difference of 25.5%. between the control and Intervention groups) In Separate country-specific analysis, the net increase in the proportion of high-risk individuals taking aspirin was higher in China (24.5%) than in India (9.8%), but both were highly significant. There was a significant net reduction in mean SBP in China (-4.1 mmHg, P=0.006) but a non-significant decline in India. Both countries had large net increases (>16%) in the proportion of high-risk patients receiving monthly follow-up.
Use of a Multidrug Pill in reducing cardiovascular Events (UMPIRE) Trial: UMPIRE Trial is a phase 3 – randomised, controlled clinical trial of fixed-dose combination medication, Red Heart Pill, in patients (1000 in Europe and 1000 in India) at high risk of cardiovascular disease. The Red Heart Pill contains low dose aspirin, statin and two blood pressure lowering medicines and will be compared to usual cardiovascular medications to test its effect on adherence and change in blood pressure and LDL cholesterol at 12 months. The trial has completed recruiting 1000 patients each in India and Europe by July 2011; end of study visits have begun and are expected to be complete by July 2012. The Imperial College London is the International Coordinating Center while in India the study is coordinated by George Institute India, Hyderabad and CCDC, New Delhi.
