Prevalence of coronary heart disease and major cardiovascular risk factors in Thailand.

BACKGROUND: Coronary heart disease (CHD) is expected to become one of the major health problems in developing countries such as Thailand where prevalence data are scarce. This study reports the prevalence of CHD, as indicated by electrocardiogram (ECG) Minnesota coding, and its risk factors in Thailand. METHODS: In 1991 we conducted a cross-sectional ECG survey in a multistage random sample of the Thai population, aged > or =30. All major cardiovascular risk factors were measured. Standard supine 12-lead ECG data were collected; amplitudes and intervals were measured manually and entered into a computer. Abnormal tracings were verified by five cardiologists, and agreement among at least three of them was accepted as final. RESULTS: The total sample included 3822 men and 4967 women aged > or =30 years. The age-standardized prevalence rate of CHD was 9.9/1000 (men 9.2/1000, women 10.7/ 1000). The age-standardized level of major cardiovascular risk factors among men and women respectively were: total cholesterol 4.8 mmol/l (187.3 mg/dl), 5.1 mmol/l (197.7 mg/dl); hypercholesterolaemia (> or =6.2 mmol/l) 12.2%, 16.9%; systolic blood pressure (mmHg) 117.8, 117.7; diastolic blood pressure (mmHg) 76.9, 75.8; body mass index (kg/m2) 21.7, 22.8; fasting blood sugar 4.8 mmol/l (87.9 mg/dl), 5.0 mmol/l (90.3 mg/dl); hypertension (> or =160/95 +/- on antihypertensive drugs) 6.3%, 8.1%; smoking 65.1%, 8.5%; diabetes mellitus (> or =7.8 mmol/l) 2.4%, 3.7%; obesity (>25 kg/m2) 15.2%, 27.2%. CONCLUSIONS: Most of the age-adjusted mean values and proportion of major cardiovascular disease risk factors as well as the prevalence of total CHD in the Thai population were much lower than the median of those values found in developing countries.

Research priorities for tobacco control in developing countries: a regional approach to a global consultative process.

OBJECTIVE: To develop regional tobacco control research agendas for developing countries through a consultative process. METHODS: Research for International Tobacco Control, located at the International Development Research Centre in Ottawa, Canada, convened three regional meetings for Latin America and the Caribbean, South and Southeast Asia, and Eastern, Central and Southern Africa. Participation by researchers, policymakers, and advocates from a wide range of disciplines ensured an accurate representation of regional issues. RESULTS: The four main recurring themes within each regional agenda were: (1) the lack of standardised and comparable data; (2) the absence of a network for communication of information, data, and best practices; (3) a lack of adequate capacity for tobacco control research, especially in non-health related areas such as economics and policy analysis; and (4) a need for concerted mobilisation of human and financial resources in order to implement a comprehensive research agenda, build partnerships, and stimulate comparative research and analysis. Specific research issues included the need for descriptive data with respect to the supply side of the tobacco equation, and analytical data related to tobacco use, production and marketing, and taxation. CONCLUSIONS: There was a uniform perception of tobacco as a multidisciplinary issue. All regional agendas included a balance of health, economic, agricultural, environmental, sociocultural, and international trade concerns. Research data are urgently required to provide a sound basis for the development of tobacco control policies and programmes. As tobacco control takes its rightful place on the global health agenda, it is vital that funding for tobacco control research be increased.
