RESUMEN

OBJETIVO: Evaluar la posible asociación de la edad, el sexo, el sobrepeso, los antecedentes familiares de hipertensión arterial (HTA), el alcoholismo y el sedentarismo con la HTA en la población adulta de la ciudad de Colima, México. MÉTODOS: Estudio transversal analítico de base poblacional. Se aplicó una encuesta estructurada a 280 adultos mayores de 30 años que residían en la ciudad mexicana de Colima en 2001 y 2002. Las variables estudiadas fueron el sexo, la edad, el peso, la talla, los antecedentes familiares de HTA, la práctica de ejercicio físico, el tabaquismo y el consumo de alcohol. La presión arterial (PA) se midió por el método auscultatorio. Las mediciones limítrofes o dudosas se repitieron cuatro o cinco días después. Se consideró que había HTA cuando la PA sistólica era >140 mm Hg y la presión arterial diastólica era > 90 mm Hg, o la persona estaba bajo tratamiento antihipertensivo. Se calcularon las razones de posibilidades (odds ratios, RP) de las variables estudiadas y sus intervalos de confianza de 95 por ciento (IC95 por ciento). La asociación entre las variables y la HTA se estimó mediante regresión logística y la interacción mediante el coeficiente de productos de interacción. RESULTADOS: La prevalencia bruta de HTA fue de 28,6 por ciento. La prevalencia fue mayor en hombres que en mujeres (42,1 por ciento frente a 19,2 por ciento, respectivamente; RP = 3,04; IC95 por ciento: 1,8 a 5,2) y en personas mayores de 49 años que en personas de 30 a 49 años (36,8 por ciento frente a 21,9 por ciento, respectivamente; RP = 2,07; IC95 por ciento: 1,22 a 3,50). Los antecedentes familiares de HTA y el sobrepeso mostraron asociación con la HTA, mientras que la práctica de ejercicio físico tuvo un efecto protector (RP = 0,45; 0,23 a 0,86). Se encontró interacción entre la HTA y la edad (> 50 años), los antecedentes familiares de HTA, el sobrepeso y la práctica de ejercicio físico, particularmente en mujeres. CONCLUSIONES: La prevalencia de HTA en Colima es muy semejante a la encontrada a nivel nacional en México. Su fuerte asociación con el sexo masculino, independientemente de las otras variables, resalta la necesidad de promover campañas preventivas más enfocadas en los hombres.

Objective. To evaluate the possible association that age, sex, excess weight, family history of hypertension, alcoholism, and sedentary lifestyle have with hypertension in the adult population of the city of Colima, Mexico. Methods. This was a population-based analytic cross-sectional study. A structured survey was used with 280 adults older than 30 years of age who were living in the city of Colima in 2001 and 2002. The variables studied were sex, age, weight, height, family history of hypertension, engaging in physical exercise, smoking, and consuming alcohol. Blood pressure (BP) was measured with the auscultatory method. Borderline ordoubtful measurements were checked again four or five days later. Hypertension was defined as systolic BP ≥ 140 mm Hg and diastolic blood pressure ≥ 90 mm Hg, or as the person being under antihypertensive treatment. The odds ratios (ORs) of the variables studied were calculated, along with their 95% confidence intervals (95% CIs). The association between the variables and hypertension was estimated through logistic regression, and their interaction through the coefficient of the interaction products. Results. The overall prevalence of hypertension was 28.6%. The prevalence was higher in men than in women (42.1% vs. 19.2%; OR = 3.04, 95% CI: 1.8 to 5.2) and in people older than 49 years than in people 30 to 49 years old (36.8% vs. 21.9%; OR = 2.07, 95% CI: 1.22 to 3.50). A family history of hypertension and excess weight were associated with hypertension, while physical exercise had a protective effect (OR = 0.45; 95% CI: 0.23 to 0.86). There was interaction between hypertension and age ≥ 50 years, a family history of hypertension, overweight, and physical exercise, especially among women. Conclusions. The prevalence of hypertension in Colima is very similar to that for Mexico as a whole. The strong association that hypertension had with male gender, regardless of the other variables, emphasizes the need for promoting prevention campaigns that focus more on men

RESUMEN

OBJECTIVE: To evaluate the possible association that age, sex, excess weight, family history of hypertension, alcoholism, and sedentary lifestyle have with hypertension in the adult population of the city of Colima, Mexico. METHODS: This was a population-based analytic cross-sectional study. A structured survey was used with 280 adults older than 30 years of age who were living in the city of Colima in 2001 and 2002. The variables studied were sex, age, weight, height, family history of hypertension, engaging in physical exercise, smoking, and consuming alcohol. Blood pressure (BP) was measured with the auscultatory method. Borderline or doubtful measurements were checked again four or five days later. Hypertension was defined as systolic BP > or = 140 mm Hg and diastolic blood pressure > or = 90 mm Hg, or as the person being under antihypertensive treatment. The odds ratios (ORs) of the variables studied were calculated, along with their 95% confidence intervals (95% CIs). The association between the variables and hypertension was estimated through logistic regression, and their interaction through the coefficient of the interaction products. RESULTS: The overall prevalence of hypertension was 28.6%. The prevalence was higher in men than in women (42.1% vs. 19.2%; OR = 3.04, 95% CI: 1.8 to 5.2) and in people older than 49 years than in people 30 to 49 years old (36.8% vs. 21.9%; OR = 2.07, 95% CI: 1.22 to 3.50). A family history of hypertension and excess weight were associated with hypertension, while physical exercise had a protective effect (OR = 0.45; 95% CI: 0.23 to 0.86). There was interaction between hypertension and age > or = 50 years, a family history of hypertension, overweight, and physical exercise, especially among women. CONCLUSIONS: The prevalence of hypertension in Colima is very similar to that for Mexico as a whole. The strong association that hypertension had with male gender, regardless of the other variables, emphasizes the need for promoting prevention campaigns that focus more on men.
