ABSTRACT
Studies have reported that both gender and adiposity influence cardiovascular reactivity amongst adolescents. However, not much is known about the effect of gender on the association of adiposity with cardiovascular reactivity. The current study was conducted to learn how gender affects the association of adiposity with cardiovascular reactivity in the Gujarati Indian adolescents so as to develop preventive strategies for the local population. A cross-sectional study was conducted on 428 (Girls-173, Boys- 255) Gujarati Indian adolescents of age group 16-19 years. Adiposity was assessed in terms of Body Mass Index (BMI), Body Fat Percentage (BF %), Fat Mass (FM), Fat Mass Index (FMI) and Waist Circumference (WC). Percentage Rise in Pulse Rate (%RPR) and Percentage Rise in Diastolic Blood Pressure (%RDBP) during Isometric Handgrip Test were used to assess the cardiovascular reactivity to acute sympathetic stress. Pearson’s correlation coefficient was determined to find the association of adiposity with cardiovascular reactivity. Boys were found to have a significantly larger WC, higher physical fitness and greater %RDBP in comparison to girls while girls had a significantly higher BF% and FMI in comparison to boys. In both boys and girls, BMI, BF%, FMI and WC showed significant positive association with %RDBP with stronger correlationship found in girls. Girls also showed a significant negative correlationship between physical fitness and vascular reactivity. It could thus be concluded that gender affected the association of adiposity with vascular reactivity in Gujarati Indian adolescent such that girls tend to have a larger correlationship between adiposity and vascular reactivity than boys which is most likely due to lower physical fitness.
ABSTRACT
OBJETIVO: Determinar la relación entre la adiposidad total y su distribución abdominal con los niveles de tensión arterial en mujeres de edad mediana. MÉTODOS: Se realizó un estudio descriptivo transversal en cuatro consultorios del Policlínico Universitario 19 de Abril del municipio Plaza de la Revolución. Se estudiaron 229 mujeres, entre 45 y 59 años, a los cuales se les determinó el índice de masa corporal (IMC), se midió la circunferencia de la cintura y se tomaron las cifras de tensión arterial. RESULTADOS: El 72 por ciento de las mujeres estudiadas tenían exceso de peso, el 38 por ciento circunferencia de la cintura ³88 cm, el 37 por ciento era hipertensas. Una asociación altamente significativa se encontró entre el IMC y la hipertensión arterial y entre la circunferencia de la cintura (CC) y la hipertensión arterial. Hubo una incidencia de 65 pacientes prehipertensas y 11 hipertensas. CONCLUSIÓN: El porcentaje de hipertensas aumenta según se incrementa el IMC, la hipertensión arterial es más frecuente en mujeres con CC ³ 88 cm, el porcentaje de hipertensión arterial es mayor en las mujeres posmenopáusicas
OBJECTIVE: To determine the relationship between the total adiposity and its abdominal distribution with the arterial pressure levels in middle-age women. METHODS: A cross-sectional and descriptive study was conducted in four consulting rooms of the 19 de Abril University Polyclinic from the Plaza de la Revoluci¾n municipality. A total of 229 women aged between 45 and 59 were studied to determine the body mass index (BMI), waist circumference (WC) was measured registering the arterial pressure figures. RESULTS: The 72 percent of study women had excess weight; the 38 percent had a waist circumference ³88 cm, the 37 percent was hypertensive. There was a highly significant association between the BMI and the high blood pressure and between the WC and the high blood pressure. There was also an incidence of 65 pre-hypertensive patients and 11 hypertensive patients. CONCLUSION: The hypertensive percentage increases according to an increase in BMI, the high blood pressure is more frequent in women with WC = 88 cm, the high blood pressure percentage is greater in postmenopausal women
