    A cross sectional study of the microeconomic impact of cardiovascular disease hospitalization in four Low and Middle –Income Countrie
    (PLoS One, 2011) Huffman, MD; Rao, KD; Pichon-Riviere, A; Zhao, D; Harikrishnan, S; Ramaiya, K; Ajay, VS; Goenka, S; Calcagno, JI; Caporale, JE; Niu, S; Li Y; Liu, J; Thankappan, KR; Daivadanam, M; Esch, JV; Murphy, A; Moran, AE; Gaziano, TA; Suhrcke, M; Reddy, KS; Leeder, S; Prabhakaran, D
    OBJECTIVE: To estimate individual and household economic impact of cardiovascular disease (CVD) in selected low- and middle-income countries (LMIC). BACKGROUND: Empirical evidence on the microeconomic consequences of CVD in LMIC is scarce. METHODS AND FINDINGS: We surveyed 1,657 recently hospitalized CVD patients (66% male; mean age 55.8 years) from Argentina, China, India, and Tanzania to evaluate the microeconomic and functional/productivity impact of CVD hospitalization. Respondents were stratified into three income groups. Median out-of-pocket expenditures for CVD treatment over 15 month follow-up ranged from 354 international dollars (2007 INT$, Tanzania, low-income) to INT$2,917 (India, high-income). Catastrophic health spending (CHS) was present in >50% of respondents in China, India, and Tanzania. Distress financing (DF) and lost income were more common in low-income respondents. After adjustment, lack of health insurance was associated with CHS in Argentina (OR 4.73 [2.56, 8.76], India (OR 3.93 [2.23, 6.90], and Tanzania (OR 3.68 [1.86, 7.26] with a marginal association in China (OR 2.05 [0.82, 5.11]). These economic effects were accompanied by substantial decreases in individual functional health and productivity. CONCLUSIONS: Individuals in selected LMIC bear significant financial burdens following CVD hospitalization, yet with substantial variation across and within countries. Lack of insurance may drive much of the financial stress of CVD in LMIC patients and their families.

    A Cross-Sectional Study of the Microeconomic Impact of Cardiovascular Disease Hospitalization in Four Low- and Middle-Income Countries

    Prevalence and determinants of diabetes mellitus in the Indian industrial population
    (Diabetic Medicine, 2008) Ajay, VS; Prabhakaran, D; Jeemon, P; Thankappan, KR; Mohan, V; Ramakrishnan, L; Joshi, P; Ahmed, FU; Mohan, BVM; Chaturvedi, R; Mukherjee, R; Reddy, KS
    AIM: To highlight the regional difference in the prevalence of diabetes mellitus (DM) and to explore determinants in variability in the Indian industrial population. METHODS: A cross-sectional survey was carried out among the employees and their family members (10 930 individuals, mean age 39.6 years, 6764 male) of eleven medium-to-large industries from diverse sites in India, using a stratified random sampling technique. Information on behavioural, clinical and biochemical risk factors of DM was obtained, through standardized instruments. DM was diagnosed when fasting blood glucose was > or = 7.0 mmol/l and/or individuals took drug treatment for DM. Multiple logistic regression analysis was carried out to identify the potential predictors of DM. RESULT: In the 20 to 69-year-old age group, the crude prevalence of DM and impaired fasting glucose was 10.1 and 5.3%, respectively. Urban sites had a higher prevalence and awareness of DM status. Individuals in the lower education group had a high prevalence of DM (11.6%). In diabetic subjects, 38.4% were unaware that they had diabetes. Waist-circumference-to-height ratio had a higher DM predictive power than waist circumference and body mass index. The risk factors associated with overall prevalence of DM were: age, sex, low-education level, family history of DM, hypertension and overweight/obesity. Interaction of risk factors was observed only in urban high-prevalence sites. CONCLUSION: There are wide regional variations in the prevalence of DM in India. The high burden of undetected diabetes, even in settings with universal access to on-site health care, highlights the need for innovative prevention and control strategies.
