INTRODUCTION Systematic measurement of population physical activity levels is an important component of public health surveillance.
OBJECTIVES Describe patterns of physical activity in the Cuban population aged 15–69 years and identify factors associated with regular physical activity.
METHODS A descriptive cross-sectional study was conducted using a complex sampling design, representative of urban and rural areas, sex and age groups, including 7915 individuals. The International Physical Activity Questionnaire (short format) was applied. The population was classified as active, irregularly active and sedentary, according to sex, age, marital status, education, skin color, employment and perception of health risk related to physical inactivity or overweight. Percentages, odds ratios (OR) and 95% confidence intervals (CI) were calculated and a multinomial regression model was fitted with active persons as the reference category.
RESULTS Approximately 71% of the population self-classified as active, 23% as sedentary and 5.9% as irregularly active. Women had a higher probability of being sedentary (OR 2.51, CI 2.12–2.98) and irregularly active (OR 2.56, CI 95% 1.87–3.49). The probability of being sedentary increased with age (OR 1.19, CI 1.12–1.26), and also with the condition of being a homemaker, retired, or unemployed. Perceiving overweight as a high risk to health reduced likelihood of inactivity (OR 0.49, CI 0.29–0.83).
CONCLUSIONS Some 7 of 10 Cubans are physically active. The groups with the highest probability of inactivity and irregular activity and associated factors have been identified through national application (for the first time) of the International Physical Activity Questionnaire. The results should be taken into account for implementation of specialized strategies to promote systematic physical activity.

Las enfermedades crónicas no transmisibles se consideran la pandemia del siglo XXI y constituyen un desafío de alta prioridad para la salud pública; de ahí el creciente interés en la vigilancia de los factores de riesgo de las enfermedades crónicas. Cuba desarrolla la vigilancia de los factores de riesgo de forma descentralizada en cada uno de sus municipios como parte de la estrategia para enfrentar las enfermedades no transmisibles. No tiene precedentes en Cuba la vigilancia descentralizada con este nivel de detalle y diseñada expresamente para informar a los decisores en el municipio y la provincia. Se describe la metodología empleada para planificar y realizar la medición de los principales factores de riesgo en 12 municipios de 10 provincias, como parte del sistema nacional de vigilancia de Cuba. Los resultados han facilitado el uso oportuno de la información y la toma de decisiones basadas en pruebas a nivel local.

Chronic non-communicable diseases have been called the pandemic of the 21st century and constitute a high-priority public health challenge; hence growing interest in chronic disease risk factor surveillance. Cuba is implementing decentralized risk factor surveillance in each of its municipalities as part of a strategy to address non-communicable diseases. Decentralized surveillance with this level of detail and explicitly designed to inform municipal and provincial decisionmaking is unprecedented in Cuba. We describe the methodology for planning and implementing measurement of major risk factors in 12 municipalities in 10 provinces, as part of Cuba’s National Surveillance System. The results have facilitated timely use of information and evidence-based decisionmaking at the local level.

INTRODUCTION Tobacco and alcohol are currently the most widely consumed legal psychoactive substances in the world. They represent a heavy burden for health and society in almost all populations. Increasing consumption of both substances is a trend observed in women.
OBJECTIVE Describe the profile of women aged ≥15 years residing in urban areas of Cuba with respect to tobacco and alcohol consumption.
METHOD Basic information on tobacco and alcohol consumption by Cubans aged ≥15 years in urban areas was obtained from the Second National Survey on Risk Factors and Chronic Diseases (2001), a national descriptive cross-sectional study, the objective of which was to determine the frequency and epidemiological characteristics of the urban population’s main chronic disease risk factors. Sampling design was complex stratified multi-stage cluster. Of a sample of 23,743 individuals, 22,851 were surveyed, representative of 6.8 million Cubans. A questionnaire and structured interview were used. Variables were tobacco and alcohol use, as well as sociodemographic factors: sex, age, educational level, skin color, marital status, type of full-time employment and perceived economic situation. Prevalence, with 95% confidence intervals, and male:female prevalence ratios were estimated.
RESULTS Women who smoked were predominantlyaged 40–59 years; had completed less than university education; of black skin color; divorced; laborers, service workers or managers, and with a perceived economic situation as very poor. Women who consumed alcohol were predominantly aged 15–59 years, had at least middle school education, of mestizo or black skin color, of marital status other than widowed; there was no typical profile for occupation or perceived economic situation. Women who were both smokers and alcohol consumers were predominantly 20–59 years, of black or mestizo skin color, of marital status other than widowed; with no typical profile for educational level, occupation or perceived economic situation.
CONCLUSIONS The first nationwide socioeconomic profile of Cuban women using tobacco, alcohol or both constitutes a baseline for comparison to results of a new national study now under way, permitting evaluation of trends over time and effectiveness of prevention and control efforts.

Introduction Smoking is the main preventable cause of death worldwide. The World Health Organization estimates that smoking causes 5 million deaths annually, a figure that could double shortly if the present trend in tobacco product consumption continues.
Objectives Estimate smoking-attributable mortality in the Cuban population and provide information needed to carry out effective public health actions.
Methods This is a descriptive study using smoking prevalence and mortality data in Cuba for 1995 and 2007. Causes of death were grouped in three categories: malignant tumors, cardiovascular diseases and chronic respiratory diseases. Etiological fractions and attributable mortality were calculated by cause and sex.
Results Of deaths recorded in 1995 and 2007, 15% and 18% of preventable deaths were attributed to smoking, respectively. In Cuba in 2007, smoking caused 86% of deaths from lung cancer, 78% of deaths from chronic obstructive pulmonary disease, 28% of deaths from ischemic heart disease, and 26% of deaths from cerebrovascular disease.
Conclusions Smoking is responsible for high rates of preventable mortality in Cuba. There is willingness on the part of administrative and political authorities to discourage smoking, and more than half of smokers in Cuba wish to quit smoking. Given awareness that reducing smoking is the most effective means of decreasing preventable morbidity and mortality, the country is moving steadily toward concrete, sustainable steps leading to increased life expectancy and quality of life for the Cuban population.
