Statement of Research Interests
In Asia, there is an imperative need to implement the practice of evidence-based public health policy, planning, and spending. My earlier and ongoing research provides the appropriate evidence, which can guide the formulation of policy to bring in positive change that we can see in our lifetime. I am focused shaping my career towards independence and in building a long-term career in academic public health. Therefore, my future research plan is dedicated to exploring the impact of tackling determinants in the maternal and psychosocial environment and thereby promote positive health in populations through appropriate interventions.
The focus of my research is through the realization of the following objectives.
- Generating evidence regarding maternal and psychosocial environment of NCDs
- Explore the appropriate interventions through pilot projects
- Ensuring evidence-based public health policy planning and implementation
Objectives (a) and (b) help in identification and prioritization of maternal determinants of childhood obesity (and subsequent risk of diabetes and hypertension) in Asia. The evidence available in the next three years will aid in the generation of rigorous, feasible and contextually specific population-based pilot interventions. The objective (c) will be achieved through the implementation of pilot interventions based on objectives (a) & (b). The three objectives together will contribute to logical and empirically grounded choices of public health interventions.
In the next few years, I want to pilot the interventions based on the results of the research on the role of the maternal and psychosocial environment of NCDs in different populations. The overall results from testing the interventions will result in the implementation of evidence-based public health. In the next 5 years, I wish to inculcate the evidence into policy formulations at the national and international level to influence policymakers to bring positive changes with respect to NCD prevention and control. Due to demographic transition and lifestyle changes, the aging Asian populations continually are affected by NCDs. My engagement of research and advocacy in NCDs will aid in improving the health of an aging population and improve productivity. I am uniquely positioned to study the effects from an intergenerational perspective and earnestly believe that the positive changes will see the transformation of societies in the next two decades. Therefore, my long-term goal is to ensure healthy populations are sustained through integrated technical and advocacy efforts. My track record of working in public health over 17 years has provided a clear resolve for the achieving the objectives listed above.

Summary: Hypertension is a major contributor to the worldwide epidemic of cardiovascular disease (CVD).[1,2] It is estimated that hypertension causes 7.5 million deaths worldwide amounting to 12.8% of the total of all annual deaths. Many risk factors leading to hypertension are modifiable and therefore provide an opportunity for preventive efforts. There is an imperative need for population-based research to understand the modifiable factors such as job stress in leading to Hypertension. I chose workplace settings for the research as they provide opportunities to explore determinants of these negative behaviors and are amenable to interventions.
I led a moderately large study (N = 1071) in the software professionals in Bangalore, India employed at 27 different IT companies. The focus of our study was to study the association of Job stress and Hypertension as well as understanding the on the age gradient of hypertension prevalence. The research established a higher prevalence of hypertension in the younger age cohort, affecting 31% professionals with 5% having malignant levels of hypertension. It was known earlier that south Asians are predisposed to be hypertensive a decade earlier compared the developed countries. Our research suggested that hypertension in IT/ITES professionals occurs a decade earlier compared to the rest of India and two decades earlier compared to developed countries. This suggests that if untreated, these professionals would go on to develop cardiovascular diseases (CVD) at an early age. The results also indicated that 46% of professionals were in pre-hypertension. In addition, I found that the dimensions of workplace autonomy and workplace environment are associated with hypertension.
- The earlier understanding was that the association between job strain and coronary heart disease (CHD) is weak, with job strain slightly increasing the risk of coronary diseases by 3.4% in the general population. Our meta-analysis showed statistically significant associations with 30% higher risk of hypertension for those with job strain. This proves that job strain might be affecting the CHDs through hypertension. The paper on the meta-analysis of job stress and hypertension, therefore, is a significant contribution to the body of literature and would influence future research delineating the effects of stress on CHDs. As a testimony to the impact of the paper, the original paper by us was republished by the BMJ group in their postgraduate medical journal.
- It is important that individuals with higher stress have to change their lifestyle to prevent a progressive rise in BP using the recommended lifestyle modifications.  As a result of the findings from the study, the software companies have approached us and have requested to engage with them for improving health outcomes. I am in discussion with a major IT company to finalize the details of engagement towards improving the health of the employees.

- Subsequent to the study in software professionals, we have now conducted the study in schoolteachers and employees of the health department. These studies are helping us to collate evidence on the worksite-based burden of NCDs and are helpful in designing the appropriate interventions. A series of papers are pending for publications on the burden of the diseases in different workgroups.
