Examining the effectiveness of India’s conditional maternal benefit programme on infant survival: Using data to clarify health inequality in developing countries

Research Topic

Transition of the inequality in non-communicable diseases in low- and middle-income countries in Asia

Due to rapid economic development over the past 20 years, most Asian countries enjoy longer life expectancies. However, non-communicable diseases (NCDs) such as cardiovascular diseases, diabetes and strokes, now outnumber infectious diseases as a cause of death. As prevalence of NCDs are substantially influenced by both individual lifestyles and socioeconomic status, its socioeconomic inequality has also been greatly changing. My research aims to develop methodological framework in the health inequality study and provide empirical evidence that would contribute to policies in low- and middle-income countries in Asia.
