Duración de sueño en personas mayores con síndrome metabólico

Sleep is a quality-of-life indicator. Sleep alterations have health consequences. The objective of the study was to analyze the sleep pattern in elderly people with metabolic syndrome. A cross-sectional study was carried out on a sample of 326 participants of node 01 of the PREDIMEDPLUS study (University of Malaga). The hours of sleep were quantified objectively with an accelerometer, and subjectively, with a self-reported questionnaire. The average duration of sleep (hours) measured with the accelerometer was higher in women (6.6±0.1) than in men (6.2±0.1); these data differ from self-reported data of 6.7h±0.1 hours in men and 7.3h±0.1 in women. 43% of men and 30% of women sleep less than 6 hours. A high percentage of participants have a poor sleep. In addition, future methodological investigations of sleep assessment are needed.El sueño es un indicador de la calidad de vida. Sus alteraciones pueden afectar la salud. El objetivo del estudio fue analizar el patrón de sueño en personas mayores con síndrome metabólico. Se realizó un estudio transversal en 326 participantes del nodo 01 del Estudio PREDIMEDPLUS (Universidad de Málaga). Las horas de sueño se cuantificaron de forma objetiva con un acelerómetro, y de manera subjetiva, a partir de un cuestionario. La duración media del sueño (horas) medida con el acelerómetro fue mayor en mujeres (6,6 ± 0,1) que en hombres (6,2 ± 0,1); estos datos difieren de los auto-declarados de 6,7 ± 0,1 horas en hombres y 7,3 ± 0,1 en mujeres. Un 43 % de hombres y un 30 % de mujeres duermen menos de 6 horas. Un alto porcentaje de los participantes tienen un sueño deficiente. Además, se necesitan futuras investigaciones metodológicas de la evaluación del sueño

Alexitimia y depresión en mayores que practican actividad física dirigida

Associations between alexithymia and depression and sociodemographic factors have been investigated in elderly population. Whether exercise plays a role as a protective factor against these conditions has yet to be determined. Thus, the aim of this study was to investigate alexithymia and depression and its association with physical activity in elderly people. Twenty-seven participants, 9 men and 18 women (aged 64 ± 5.1). Subjects were assigned to either a sedentary group or a physically active group. All participants filled in Yesavage Scale, Toronto Alexithymia Scale (TAS)-20 and SF-12. Data were analyzed using Student’s t-test andmultiple linear regression analyses. Results showed that physically active elderly people scored lower for alexithymia and depression than sedentary subjects. These findings suggest that physical activity may have a role in benefiting mental disorders.La relación entre la alexitimia y la depresión y los factores sociodemográficos ha sido estudiada en personas mayores. Sin embargo, el papel atenuador del ejercicio en estas afecciones aún debe ser determinado. En el presente estudio se mide el grado de alexitimia y depresión en adultos mayores, comparando una muestra sedentaria con una de practicantes de actividad física. Se utilizó un diseño descriptivo transversal con una muestra compuesta por 27 participantes, 9 hombres y 18 mujeres de más de 60 años (64±5.1 años), con objeto de medir el grado de alexitimia y depresión que presentaban en el momento de la recogida de datos. Los instrumentos utilizados fueron la escala de depresión de Yesavage, la Escala de Alexitimia de Toronto (TAS-20) y el Cuestionario de Salud SF-12. Los resultados mostraron que los practicantes de actividad física presentaban puntuaciones más bajas en alexitimia y depresión que los sujetos sedentarios, sin que éstas variables estuvieran relacionadas en función del género y la edad. A tenor de los resultados, el ejercicio pudiera jugar algún papel en la modulación de las alteraciones psicológicas.

Isotemporal substitution of inactive time with physical activity and time in bed: Cross-sectional associations with cardiometabolic health in the PREDIMED-Plus study

© 2019 The Author(s). Background: This study explored the association between inactive time and measures of adiposity, clinical parameters, obesity, type 2 diabetes and metabolic syndrome components. It further examined the impact of reallocating inactive time to time in bed, light physical activity (LPA) or moderate-To-vigorous physical activity (MVPA) on cardio-metabolic risk factors, including measures of adiposity and body composition, biochemical parameters and blood pressure in older adults. Methods: This is a cross-sectional analysis of baseline data from 2189 Caucasian men and women (age 55-75 years, BMI 27-40 Kg/m2) from the PREDIMED-Plus study (http://www.predimedplus.com/). All participants had ≥3 components of the metabolic syndrome. Inactive time, physical activity and time in bed were objectively determined using triaxial accelerometers GENEActiv during 7 days (ActivInsights Ltd., Kimbolton, United Kingdom). Multiple adjusted linear and logistic regression models were used. Isotemporal substitution regression modelling was performed to assess the relationship of replacing the amount of time spent in one activity for another, on each outcome, including measures of adiposity and body composition, biochemical parameters and blood pressure in older adults. Results: Inactive time was associated with indicators of obesity and the metabolic syndrome. Reallocating 30 min per day of inactive time to 30 min per day of time in bed was associated with lower BMI, waist circumference and glycated hemoglobin (HbA1c) (all p-values < 0.05). Reallocating 30 min per day of inactive time with 30 min per day of LPA or MVPA was associated with lower BMI, waist circumference, total fat, visceral adipose tissue, HbA1c, glucose, triglycerides, and higher body muscle mass and HDL cholesterol (all p-values < 0.05). Conclusions: Inactive time was associated with a poor cardio-metabolic profile. Isotemporal substitution of inactive time with MVPA and LPA or time in bed could have beneficial impact on cardio-metabolic health. Trial registration: The trial was registered at the International Standard Randomized Controlled Trial (ISRCTN: http://www.isrctn.com/ISRCTN89898870) with number 89898870 and registration date of 24 July 2014, retrospectively registered
