In March 2020, the World Health Organization (WHO) classified the infection of the coronavirus (SARSCoV2; COVID-19) as a global pandemic. To control the virus spread, many countries imposed important restrictions such as closures of business establishments, public parks, gyms or sport facilities, in addition to limited access to public transportation. While these measures helped to control further transmission of the virus, they also fostered undesirable lifestyle changes such as reduction in levels of physical activity (PA), higher intake of alcohol and unhealthy food which have adversely impacted physical and mental health and mental wellbeing since increased levels of stress, anxiety, and depression were described during this period.  This study aims to explore changes in physical activity, estimated cardiorespiratory fitness (VO2max), risk factors status and food intake between pre-COVID-19 pandemic and current time among the adult population of India, Indonesia, Tanzania, Lebanon, Brazil, Colombia, Uruguay, and Argentina. It also aims to explore how these changes are associated with the current mental wellbeing of participants by assessing their anxiety and depression symptoms.

Title: Potential impact of salt reformulation programs in processed foods in Mexico: a modeling study
Budget: $33,383
Start date: 6/1/22
End date: 9/30/23
Co-investigators: Josiemer Mattei, Tonatiuh Barrientos-Gutiérrez, Juan Rivera
Mentors: Josiemer Mattei, Tonatiuh Barrientos-Gutiérrez 

Cardiovascular disease is the first cause of death in Mexico; 52% of CVD deaths in the country are attributable to high blood pressure and 34% to dietary risks. Sodium intake increases high blood pressure and the risk of CVD. The Mexican government is interested in salt reduction programs, but no steps have been undertaken to implement a long-term salt reformulation program. While many modeling studies have addressed the future impact of sodium reduction, no studies have focused on which processed foods should be targeted to achieve the proposed salt reductions. This study aims to identify the range of sodium reductions on multiple processed foods worldwide and estimate the cost-effectiveness of establishing a mandatory law to set maximum limits of sodium content in processed foods. The results may further support salt reductions in Mexico towards the goal of reducing hypertension and CVD.

Start date: 8/1/22
End date: 7/31/23
Co-investigators: Abhinav Vaidya, Uma Koirala, Archana Shrestha
Mentors: Eric Rimm, Abhinav Vaidya 

Nutrition transition contributes to increasing burden of non-communicable diseases (NCDs) in low-and middle-income countries, such as Nepal. Nutrition labels are a major instrument to help consumers make positive, healthy food choices and therefore to improve their food literacy. Nepal has limited health promotion campaigns to address food literacy and food purchasing behavior through improvement of awareness of nutrition labeling. There is also a lack of data regarding food labeling literacy among the customers in Nepal. To address these gaps, this study aims to carry out formative research to explore food labeling implementation gaps in Nepal and assess nutritional literacy and food buying behavior among customers of Lalitpur district.

End date: 6/30/23
Co-investigators: Chitra Venkateswaran, K Rajasekharan Nayar, Malu Mohan, Anand Marthanda Pillai, DS Sabida Das
Mentors: Vilma Irazola, Aswathy Sreedevi 

The effectiveness of behavioral interventions in delaying or preventing cardiovascular diseases (CVD) is currently well established in many high-income countries, but these interventions need to be culturally adapted and implemented to a real-world setting in low- and middle-income countries like India. Furthermore, not much is known about the implementation and scale-up of such programs for special occupational groups like law enforcement officers. Studies show that police officials are at greater risk for cardiovascular diseases compared to the general population. This feasibility study proposes to evaluate whether a behavioral intervention based on the Health Belief Model (HBM) can reduce modifiable risk factors of CVD through psychological and behavioral changes in policemen in Thiruvananthapuram district of Kerala state, India.

Title: Cost-effectiveness analysis of intensive blood pressure control to enhance the Universal Health
Coverage of hypertension in Iran
Budget: $9,998
Start date: 7/15/21
End date: 9/30/22
Co-investigator: Mahboubeh Parsaeia
Mentors: Goodarz Danaei, Ankur Pandya

The SPRINT trial supports that aggressive blood pressure treatment target (less than 120 mm Hg) compared with the standard treatment target (less than 140 mm Hg) significantly reduces CVD events and all-cause mortality among individuals at high risk for CVD but without diabetes.  However, lowering the blood pressure target to 130/80 mm Hg based on the2017 ACC/AHA sharply increases the prevalence of hypertension in Iran. This raises the question of whether the health gains produced by lowering the blood pressure target are worth the costs, and whether the aggressive treatment target is more cost-effective than the standard target in Iran. To answer this question, this study will consist of a model-based cost-effectiveness analysis, comparing costs and health gains of pharmacological therapy for different subpopulations based on the standard vs. aggressive treatment targets.

Despite extensive knowledge on prevention and control of hypertension, the strongest modifiable cardiovascular disease (CVD) risk factor, its incidence and prevalence continue to rise in India. Recognizing the importance of comprehensive primary care addressing non-communicable diseases, the Indian government has launched several policies and programs such as Ayushman Bharat. However, a gap remains from pharmacological and lifestyle interventions working in silos, and a lack  collaboration between healthcare providers using modern sciences and those using traditional therapeutic disciplines. The goal of this study is to assess the feasibility of an integrative, protocol-based primary care intervention for significant hypertension control.

Cardiovascular diseases  and their behavioral risk factors such as tobacco use, unhealthy diet, physical inactivity, and harmful use of alcohol are emerging public health problems in Nepal. Most of the focus, however, has been on hospital-centric curative services for CVDs, rather than on primary prevention. Our recent CVD-focused community-based interventions in Nepal have yielded success in terms of improving the knowledge and perceptions of mothers, and improving cascade of care of diabetes management through involvement of community health volunteers. This study aimed to conduct formative research to inform the design and implementation of a community-based CVD prevention intervention in the Sinamangal-Minbhawan squatter area.

End date: 11/30/22
Co-investigators: Trevor Ferguson, Ian Hambleton, Saria Hassan, Simon Anderson
Mentor: Trevor Ferguson

In Barbados, levels of hypertension (40.7%) are high and account for the highest proportion of deaths due to cardiovascular and noncommunicable diseases (NCDs). The financial implications of the high and increasing prevalence are grave especially in Barbados, which in 2018, was among the top five most indebted nations in the world. Tackling NCDs requires a multi-level approach involving the health system, providers and the individual. This study seeks to evaluate the effectiveness and cultural appropriateness of a hypertension self-management program including lifestyle workshops, self-monitoring training, and tools to enhance medication adherence, in a small island developing state with a high burden of NCDs.

Start date: 6/1/20
End date: 11/30/22
Mentors: Joseph Brain, Nancy Long Seiber

Among the Indian states, Tamilnadu ranks first in ischemic heart disease and second in diabetes mellitus, requiring urgent action. With about 25% of the population being adolescents, there is also a rise in the cardiometabolic risk factors in this age group. The existing national programs, such as the School Health Program, National Program for Prevention & Control of Cancer, Diabetes, Cardiovascular Diseases & Stroke, and the Rashtriya Kishor Sawstya Karyakram, focus on undernutrition, menstrual hygiene and substance abuse and not on NCDs, resulting in a large void of prevention. This study seeks to prevent the adult onset of cardiometabolic diseases by designing, implementing, and evaluating the effectiveness of a comprehensive school-based intervention program among adolescents aged 10-18 years in the rural area of Coimbatore, India.

 Impact of a patient-targeted MOOC on cardiovascular health outcomes and health literacy of patients with hypertension in Colombia
Budget: $39,779, with $15,000 funded by the Lown Scholars Program
Start date: 6/1/19
End date: 9/30/22
Co-investigators: Rima Rudd, Carlos Mendivil, Luis Jorge Hernandez, Jovana Ocampo, Conecta-TE, Margaret Raba
Mentor: Rima Rudd

It is expected that in 2025, almost three quarters of patients with hypertension and/or cardiovascular disease will live in developing countries. Addressing disparities is a critical component of management strategies for chronic diseases, as there is evidence shows that level of education and health literacy are associated with poorer control of hypertension. Based on recommendation by the National Academy of Sciences, the significance of this project is to improve health outcomes on a broad scale by improving health literacy and incorporating adequate teaching materials and strategies that target particular patient needs. This study aims to develop a patient-targeted massive open online course (MOOC) in cardiovascular health, guided by health literacy data from patients with cardiovascular disease. A small group of patients are planned to pilot the MOOC in a subnet of hospitals in Bogotá, and the study plans to explore their experience.

Title: Evaluation of a community engaged intervention for stroke prevention in Alappuzha, Kerala, India
Budget: $24,944
Start date: TBD
End date: TBD
Co-investigator: Rekha Rachel Philip
Mentor: Kathyrn Rexrode

In Kerala, in terms of years of life lost, stroke is the second leading cause among females and third leading cause among males. Of the stroke cases, about 15% of the patients become bedridden in the community. The Government of Kerala has realized the magnitude of the problem and has been initiating district-level stroke centers since 2017 where treatment for acute stroke is given free. Engaging the community in educating its population regarding warning signals of stroke and stroke risk factors could result in improved stroke awareness, facilitating early detection, effective thrombolytic treatment and better stroke outcomes, as well as prevention through management of stroke risk factors. This study aims to evaluate the impact of a community intervention for stroke awareness and prevention on pre-hospital time and management of risk factors.

In Uganda, the prevalence of hypertension is 26%, and only 26.7% of patients have controlled high blood pressure. Poor blood pressure control is increasing despite the availability of effective medications. Blood pressure control is much more complicated by scarcity of health professionals in most parts of the country, and up to one third of doctors leave the country in search of better jobs. This study aimed to test whether a comprehensive intervention program including community health workers, physician training, and text messaging will improve high blood pressure control among hypertensive patients attending hypertension clinics in southwestern Uganda.

Co-investigator: Marina Njelekela
Mentor: Vanessa Kerry

Rheumatic heart disease (RHD) accounts for approximately 275,000 deaths annually, and although almost eradicated in developed countries, RHD continues to affect many children and young adults in Sub Saharan African countries, including Tanzania. RHD can largely be prevented when appropriate control programs are implemented focusing on community awareness, appropriate diagnosis and treatment of its cause, namely Group A beta haemolytic Streptococcus (GAS) sore throat infection as well as proper management of Acute Rheumatic Fever. Since the most vulnerable populations for GAS throat infections are children, there is strong potential for RHD control programs to be successful when targeting primary schools, improving the reach of primary and secondary prevention as well as case detection of RHD. This study aimed to assess the feasibility and acceptability of a school-based RHD control program in Manyara Region using the World Heart Federations’s RHD control toolkit.

Co-investigator: Ramfis Nieto-Martinez
Mentor: Ramfis Nieto-Martinez

In Venezuela, cardiovascular disease is responsible for 30.5% of all deaths, increasing by 8.3% since 2007 to 2017. The prevalence of cardiometabolic risk factors in the country is also increasing. Through the VENMOLS and EVASCAM surveys, it has been estimated that 1.7 million adults could advance to type 2 diabetes (T2D) in the next three to five years. In previous studies, lifestyle interventions only showed a pooled mean weight loss 1.57 kg higher than standard care, demonstrating the large difficulties in weight loss of participants at community levels. This study aimed to improve the effectiveness of T2D prevention programs through a transculturalization process incorporating multiple validated components and by extension, positively impact T2D incidence, prevalence, quality of life, and health care costs.

Co-investigators: Alvaro Passi, Samanta Anriquez
Mentor: Goodarz Danaei

In Chile, 70% of the over-14-year-old population has chronic disease multi-morbidity (MM). People who live with 5 or more chronic diseases has increased from 11.9% to 17.5 % between 2010 and 2017 national health surveys. The Ministry of Health (MINSAL) recently proposed a national shift to a new MM-based chronic care mode, which included a new definition of MM strata. However, its capacity to predict important and costly events like hospitalizations and deaths that are amenable with primary care is not known. This study sought to contribute to a gap of knowledge using newly available and nationally representative data through cohort analysis of linked death certificates and hospital discharge data associated to the 2010 National Health Survey (Encuesta Nacional de Salud, ENS 2010). The general aim was to estimate the predictive validity of the simpler stratification definition that MINSAL wants to implement.

WHO reports that cardiovascular disease and cancer are the leading causes of mortality in Lebanon, with rates of 47% and 22%. There is also evidence from Western studies that prenatal exposure to maternal smoking is a major precursor of adverse health outcomes in the offspring, though data for risk factors to cardiovascular diseases in the Middle East is lacking. This study sought to validate environmental pollutant measurements and lifestyle assessment instruments (dietary and activity questionnaires) to be used postpartum, and to explore the impact of environmental pollutants on the obesity phenotype in mother-offspring pairs. Thus far, data on exposure to pollution of mother-infant pairs was collected and will be analyzed during the next project phase.

Argentina is the highest contributor to cardiovascular disease burden in South Latin America; at the same time, 36% of the population is uninsured and is constituted mainly of the poorest. Through a non-controlled feasibility study using a mixed methods approach, this study evaluated the feasibility of a CHW-led intervention to improve detection and risk factors management in the uninsured poor population with moderate or high CVD risk in Argentina. The proposed CHW-led intervention was feasible and well accepted to improve the detection and treatment of risk factors in the poor population with exclusive public health coverage and with moderate or high CVD risk at the primary care setting in Argentina.

This study assessed the effectiveness of a community-based education and peer support led by women self-help group members in reducing systolic blood pressure among people with hypertension in urban slums of Kochi, Kerala, India. Through consultation meetings with self-help groups, local government leaders, and participant groups, a study was designed and data collected by trained self-help group volunteers in twenty slums; community interventions followed and data analysis is ongoing. The project resulted in demand generation for better hypertension control, improved awareness, improved early detection, and improvement in positive life styles and overall blood pressure reduction in the intervention area.

This study assessed the coverage of screening, treatment, and follow-up for hypertension and diabetes by frontline health workers in two Indian states (Delhi and Himachal Pradesh) to determine inequalities in screening, treatment, and follow-up coverage by gender, poverty and caste status at facility level across two states and to characterize the workflow of frontline health workers undertaking screening, treatment and follow-up monitoring for hypertension and diabetes in these two states. The study is now embedded within the national program and will assist with state and district level decision-making to improve the delivery of CVD-related services, and engage frontline health workers in quality appraisal and equity analysis of data gathered by them.

Title: Cost-effectiveness of risk-based prevention in primary health care setting in rural and urban areas in Iran: from prediction to action (PredAction project)
Budget: $10,118
Start date: 4/15/18
End date: 4/14/19
Co-investigator: Noushin Fahimfar
Mentor: Goodarz Danaei

This study aimed to determine the clinical usefulness of the risk-based interventions for CVD prevention in urban and rural areas of Iran. Specifically, the study assessed the acceptability and preferences for treatment threshold among service users and healthcare providers in urban and rural populations by using the knowledge, attitude and practice (KAP) study and Treatment Trade-Off Method (TTM) used in shared decision making in order to determine the clinical usefulness of the Globorisk prediction model in different preferred risk thresholds for treatment by calculating the “net benefit.”

Title: Assessing the interaction between built environment and cardiometabolic risk factors: Its role on health disparities
Budget: $40,000
Start Date: 3/1/17
End Date: 2/28/18
Co-investigators: Adolfo Rubinstein, Natalia Elorriaga, Luz Gibbons, María Calderón
Mentor: Marcia Castro

This study evaluated the influence of Built Environments on health-related behaviors and cardiometabolic outcomes in the Southern Cone of Latin America, focusing on urban poor and health disparities. Food and physical activity environment and its relationship with socioeconomic status factors in four communities in Argentina, Chile and Uruguay were examined and the association between characteristics of the built environment and physical activity and diet and cardiometabolic conditions (hypertension, diabetes and obesity) were quantified in adults 40-80 years old in the four communities. The study also explored the agreement between perceived and objectively measured built environment, and their association with physical activity, diet, obesity and diabetes in the four communities.
