Obesidad sarcopénica en mujeres mayores: influencia del polimorfismo I/D de la enzima convertidora de angiotensina

INTRODUCTION Sarcopenic obesity (SO) is a term that refers to an increase of fat mass together with a decrease of muscle mass, which is suffered by a high percentage of elderly population. Physical activity seems to be a good strategy to prevent it getting worse. However, genetic factors related to the aging process and to elderlys physical fitness could have an influence on it. AIM To determine if elderly women > 60 who practice physical activity regularly had differences in sarcopenic obesity according to the I/D polymorphism from the ACE (angiotensin converter enzyme) gen. METHODS Cross-sectional study of 300 elderly women who have practiced physical exercise at least twice a week for the past two years. Anthropometric data, physical activity and sedentary behaviour questionnaire, sarcopenic obesity (determining the percentage of fat mass and total muscle mass by electrical impedance and grouping the quintiles of these values into four groups) and physical fitness assessment, as well as ACE gen genotype measured by oral mucosa sample, were evaluated. RESULTS There were significant differences (p < 0.05) in sarcopenic obesity according to ACE I/D genotype (SO values: 2.18 ACE DD vs 2.48 ACE II + ACE ID). CONCLUSIONS Women who were ACE DD presented lower risk of sarcopenic obesity than those in the ACE II and ACE ID groups.

Cumplimiento de las recomendaciones de actividad física para la salud en adultos hipertensos

INTRODUCTION It seems necessary to educate patients in the need of realize the importance of physical activity to improve their health, and specifically, about the important implications that the intensity of physical activity has for health and fitness benefits. OBJECTIVE The aim of this was to evaluate achievement of physical activity recommendations for health in a group of hypertensive controlled patients from two primary care centers: La Estación y La Algodonera located in Talavera de la Reina (Toledo). METHODS DESIGN Cross-sectional study. LOCATION Primary care centers: La Estación y La Algodonera located in Talavera de la Reina. PARTICIPANTS A total of 80 controlled hypertensive patients aged 40 to 60 years old who met the inclusion criteria were invited to the study. A sample of 52 patients obtained valid results to enter the study. MAIN MEASURES Minutes of Moderate to vigorous physical activity (MVPA), minutes of light activity and number steps were measured. Data was displayed by gender and weekdays vs weekend days. RESULTS Only 59.6% of patients achieved the minimum recommendation of 30 minutes of MVPA at least every day to improve health. Male achieved significantly more MVPA during the weekend than female did. Only women presented significant differences between MVPA during week days vs weekend days. CONCLUSIONS 59.6% of hypertensive controlled patients of our sample achieve the minimal physical activity recommendations for health; the rest of the sample should increase their physical activity to achieve the recommendation and to improve their blood pressure levels.
