RESUMEN
BACKGROUND: Global commitments to reduce cardiovascular disease (CVD) burden by 2025 will require data on CVDs from lower income countries. This study aimed to estimate the prevalence of angina, and its association with hypertension, diabetes, and depression, in six low- and middle-income countries (LMICs). METHODS: Data from the World Health Organization (WHO) Study on global AGEing and adult health (SAGE) Wave 1 from China, Ghana, India, Mexico, Russia and South Africa were utilized. Multivariable logistic regression methods were used to examine the factors associated with angina. RESULTS: A total of 31,443 respondents aged 50â¯years and over were included in these analyses. The prevalence of angina was highest in Russia (39%), lowest in China (8%), and consistently higher in women than men. Angina was comorbid with chronic conditions and depression but patterns varied across countries. Depression was negatively associated with angina among older adults in Ghana but was positively associated with angina in all other countries. Hypertension was associated with increased odds of angina among older adults in China (OR 1.9; 95% CI 1.59-2.25), India (OR 1.4; 95% CI 1.14-1.78) and Russia (OR 3.7; 95% CI 2.33-6.00). Diabetes was associated with higher odds of angina in China (OR 1.6; 95% CI 1.15-2.15), Russia (OR 2.5; 95% CI 1.57-3.87), and South Africa (OR 4.1; 95% CI 2.49-6.88). CONCLUSIONS: CVD is a significant contributor to disease burden in LMICs. Angina was often co-morbid with other conditions, therefore compelling health systems to develop longer-term integrated care systems to address co- and multi-morbidity.

OBJECTIVES: Perceived income adequacy is positively associated with self-rated health (SRH) and quality of life (QOL) among adults in higher-income countries. Additionally, older individuals often report higher levels of income adequacy. However, it is unclear if these associations, documented primarily in high-income countries, are also evident across economically and culturally distinctive low- and middle-income countries. METHODS: Data were drawn from the World Health Organization's Study on global AGEing and adult health (SAGE), a study of adults aged 50 years or older in China, Ghana, India, Mexico, the Russian Federation, and South Africa. Smaller samples of younger adults (18-49 years) were included for comparison purposes. Participants reported income adequacy, SRH, and QOL. Associations between age and income adequacy and between income adequacy and SRH/QOL were examined using country-specific logistic regression analysis. RESULTS: Older adults in China and Russia were more likely to report better income adequacy than their 18- to 49-year-old counterparts; however, the opposite was observed in Ghana and India. SRH and QOL improved as income adequacy increased in all countries. DISCUSSION: As expected, income adequacy was correlated with SRH and QOL. However, the relationship between age and income adequacy varied cross-culturally, potentially due to differences in familial and governmental financial support.

BACKGROUND: Unhealthy lifestyles and depression are highly interrelated: depression might elicit and exacerbate unhealthy lifestyles and people with unhealthy lifestyles are more likely to become depressed over time. However, few longitudinal evidence of these relationships has been collected in emerging countries. The present study aims i) to analyse whether people with unhealthy lifestyles are more likely to develop depression, and ii) to examine whether depressed people with unhealthy lifestyles are more likely to remain depressed. A total of 7908 participants from Ghana, India, Mexico and Russia were firstly evaluated in the World Health Organization's Study on Global AGEing and Adult Health (SAGE) Wave 0 (2002-2004) and re-evaluated in 2007-2010 (Wave 1). Data on tobacco use, alcohol drinking and physical activity, were collected. Logistic regressions models were employed to assess whether baseline unhealthy lifestyles were related to depression in Wave 1, among people without 12-month depression in Wave 0 and any previous lifetime diagnosis of depression, and to 12-month depression at both study waves (persistent depression). RESULTS: Baseline daily and non-daily smoking was associated with depression in Wave 1. Low physical activity and heavy alcohol drinking were associated with persistent depression. CONCLUSIONS: Unhealthy lifestyles and depression are also positively related in emerging countries. Smoking on a daily and non-daily basis was longitudinally related to depression. Depressed people with low physical activity and with heavy drinking patterns were more likely to become depressed over time. Several interpretations of these results are given. Further studies should check whether a reduction of these unhealthy lifestyles leads to lower depression rates and/or to a better clinical prognosis of depressed people.
