          La evidencia reciente muestra que los patrones de sueño nocturno pueden ser un factor que contribuye a la epidemia de obesidad, sin embargo no se ha explorado esta asociación en adultos mayores (AM). El objetivo del presente estudio es determinar la asociación entre cantidad de sueño nocturno y obesidad en AM autónomos chilenos. Se evaluaron 1.706 AM autónomos de ambos sexos, de la ciudad de Santiago de Chile, 59,9% mujeres. Se les aplicó a cada uno la encuesta de sueño de Pittsburg y una evaluación antropométrica. El 84,0% de los AM duerme menos que lo recomendado. Dormir menos horas de las recomendadas se asocia con obesidad, (OR=1,49 (IC95% 1,04- 2,13)). Sin embargo al ajustar por tabaco y medicamentos esta asociación pierde significancia ((OR=1,50 (IC95% 0,95-2,38)). Se observa una asociación entre menos horas de sueño nocturno y obesidad en AM autónomos.

          Nocturnal sleep patterns maybe a contributing factor for the epidemic of obesity. Epidemiologic and experimental studies have reported that sleep restriction is an independent risk factor for weight gain and obesity, but has not been explored this association in elderly. The objetive is to determine the association between the sleep durationand obesity in elderly Chilean autonomous.1,706 AM autonomous 59.9% women, of the city of Santiago, of Chile, was applied to each survey dream of Pittsburg and anthropometric evaluation.84.0% of the elderly population sleeps less than recommended. Sleeping less hours than recommended is associated with an increased risk of obesity. (OR=1,49 (IC95% 1.04 - 2.13)) However, without adjusting for tobacco and medicine consumption, this association loses its significance ((OR=1,50 (IC95% 0,95-2,38)). An association between less sleep hours and an increased risk of obesity in the autonomous elderly is observed.

            Aging-related sleep changes.

            Normal aging is accompanied by changes in the sleep quality, quantity, and architecture. Specifically, there appears to be a measurable decrease in the ability of the healthy elderly to initiate and maintain sleep, accompanied by a decrease in the proportion of the deeper, more restorative slow-wave sleep and rapid eye movement sleep. There is epidemiologic evidence that this impaired ability to initiate, maintain, and ultimately achieve good quality, optimal sleep may be a marker of increased mortality and neurocognitive dysfunction. Possible mechanisms related to these age-related changes in sleep include age-related changes in circadian modulation, homeostatic factors, cardiopulmonary function, and endocrine function. This article describes the normal changes in sleep physiology in the elderly.

              The Associations between Anthropometric Indices and Obstructive Sleep Apnea in a Korean Population

              Background Obesity is a major risk factor for the development of obstructive sleep apnea (OSA). Although clinical and epidemiological studies have shown that OSA and obesity are strongly associated, few Asian studies have examined the associations between anthropometric obesity indices and OSA, especially in the Korean population. The purpose of this study was to evaluate the influence of anthropometric obesity indices on OSA in a Korean population. Methods Anthropometric indices, including neck circumference, waist circumference, and body mass index, were assessed in 383 consecutive subjects with suspected OSA. Results Of the 383 subjects assessed, 316 (82.5%) were diagnosed with OSA. Neck circumference (r = 0.518), waist circumference (r = 0.570), and body mass index (r = 0.512) were correlated with the apnea-hypopnea index (p<0.001, for all). After adjusting for age, sex, alcohol consumption, and smoking, a logistic regression model showed that neck circumference [odds ratio (OR), 1.414; p<0.001)], waist circumference (OR, 1.114; p<0.001), and body mass index (OR, 1.364; p<0.001) were associated with OSA. The linear regression model showed that neck circumference (β = 3.748, p<0.001), waist circumference (β = 1.272, p<0.001), and body mass index (β = 3.082, p<0.001) were associated with apnea-hypopnea index. The cut-off values for predicting OSA were determined as 34.5 cm for neck circumference, 76.5 cm for waist circumference, and 23.05 kg/m2 for body mass index for females, and 38.75 cm for neck circumference, 88.5 cm for waist circumference, and 24.95 kg/m2 for body mass index for males. Conclusion Increased anthropometric indices were significantly associated with the presence and severity of OSA in a Korean population. In addition, this study demonstrated the cut-off values for body mass index, waist circumference, and neck circumference for increased OSA risk.
