RESUMEN
BACKGROUND: The epidemiological transition has seen a trend from communicable to non-communicable diseases in developing countries. At the pinnacle of these chronic diseases is hypertension, pre-hypertension, diabetes and obesity. This leads to increased cardiovascular morbidity and mortality worldwide. In addition, environmental and behavioural changes such as lifestyle habits represent modifiable risk factors for the development of cardiovascular diseases. The Caribbean is not immune to this trend. METHODS: This was a cross-sectional survey conducted between June and September 2009 and involved individuals 15-74 years of age. Age-gender was weighted to get as close a representative sample of the general population living in the British Virgin Islands (BVI) for more than two years to a total of 301 (n = 301, M: 144, F: 157; CI 95% +/- error 5%). The study was carried out using a handout questionnaire that included variables on age, gender socio-economic status (SES), income level, cigarette smoking, physical activity, weight, height, body mass index (BMI), blood pressure, fasting blood glucose and cholesterol. RESULTS: This study shows a prevalence of hypertension of 16.6%, pre-hypertension--29.9%, diabetes mellitus--10.0% [M: 5.6%, F: 14%, p < 0.01], impaired fasting glucose (IFG)--16.9% [M: 13.9%, F: 19.7%, p < 0.01], overweight--25.6% (M: 19.4%, F: 31.2%, p < 0.001), obesity (body mass index > 30)--23.6% (M: 17.4%, F: 29.3%, p < 0.001) [all significantly higher in women], smoking habits--16.6% and alcohol--51.2% [significantly higher in men: 22.5% and 56.7%, respectively]. Of the respondents, 43.2% had a low/inactive physical activity level. Clustering of greater than one risk factor was more pronounced for women than for men 29.6% (M: 27.1%, F: 31.8%, p < 0.05). Sedentary lifestyle (low/inactive physical activity) and obesity were the only risk factors that had a positive correlation with all four chronic diseases (p < 0.05). CONCLUSION: The above results indicate that a national strategy needs to be implemented to control cardiovascular diseases, educate the population and promote healthy lifestyle habits with particular attention to low physical inactivity and obesity.

ANTECEDENTES: La transición epidemiológica ha visto una tendencia a pasar de enfermedades comunicables a enfermedades no comunicables en los países en vías de desarrollo. En la cima de estas enfermedades crónicas se hallan la hipertensión, la pre-hipertensión, la diabetes y la obesidad. Esto conduce al aumento de la morbilidad y la mortalidad cardiovasculares a nivel mundial. Además, los cambios medioambientales y conductuales tales como los hábitos de estilo de vida, representan factores de riesgo modificables para el desarrollo de las enfermedades cardiovasculares. El Caribe no es ajeno a esta tendencia. MÉTODOS: Se trata de un estudio transversal llevado a cabo entre junio y septiembre de 2009, el cual incluyó individuos de 15 - 74 años de edad. Se ponderó la edad-género con el propósito de obtener una muestra tan representativa como fuera posible de la población general que vive en las Islas Vírgenes Británicas (IVB) por más de dos años para un total de 301 (n = 301, M: 144, F: 157; CI 95% error ± 5%). El estudio fue llevado a cabo usando hojas informativas con un cuestionario que incluían las variables: edad, género, estatus socioeconómico (ESE), nivel de ingresos, hábito de fumar, actividad física, peso, altura, índice de masa corporal (IMC), presión sanguínea, y prueba de colesterol y de glucosa en sangre en ayunas. RESULTADOS: Este estudio muestra una prevalencia de hipertensión de 16.6%, pre-hipertensión 29.9%, diabetes mellitus 10.0% [M: 5.6%, F: 14%, p < 0.01], glucosa en ayunas alterada (GAA) 16.9% [M: 13.9%, F: 19.7%, p < 0.01], sobrepeso 25.6% (M: 19.4%, F: 31.2%, p < 0.001), obesidad (índice de masa corporal > 30) 23.6% (M: 17.4%, F: 29.3%, p < 0.001) [todos significativamente más altos en las mujeres], hábito de fumar 16.6% y consumo de alcohol 51.2% [significativamente más altos en los hombres 22.5% y 56.7%, respectivamente]. De los encuestados, el 43.2% tenían un nivel de actividad física inactivo/bajo. La existencia de más de un factor de riesgo fue más pronunciada en las mujeres que en los hombres 29.6% (M: 27.1%, F: 31.8%, p < 0.05). El estilo de vida sedentario (actividad física inactiva/baja) y la obesidad fueron los únicos factores de riesgo que tuvieron una correlación positiva con las cuatro enfermedades crónicas (p < 0.05). CONCLUSIÓN: Los resultados enumerados indican que es necesario implementar una estrategia nacional a fin de controlar las enfermedades cardiovasculares, educar, y promover hábitos de estilo de vida saludables con atención particular a la actividad física baja y la obesidad.
