Estructura factorial del Cuestionario de Apoyo Social MOS en ancianos colombianos con dolor crónico / Factorial structure of the MOS Social Support Survey among senior and elder Colombian population diagnosed with chronic pain

Resumen El Cuestionario de Apoyo Social MOS es uno de los instrumentos que más se utilizan en la investigación y en la práctica gerontológica, pero no hay estudios acerca de su validez para la evaluación de ancianos colombianos. El objetivo de esta investigación fue valorar si la estructura de 4 factores descrita en otras poblaciones es válida, estudiar la fiabilidad y determinar diferencias atribuibles a género y convivencia con una pareja. Se trabajó con una muestra intencional de 463 mayores, de diversas regiones de Colombia. El análisis estadístico de los ítems evidenció ausencia de normalidad y altas correlaciones inter ítems e ítemescala (superiores a .60), por lo que se seleccionó el método de Mínimos Cuadrados no Ponderados (ULS) para el análisis factorial confirmatorio, con el que se evaluaron tres modelos (de un factor, de tres y de cuatro factores correlacionados) siendo el de 4 factores el que obtuvo mejores índices (NFI=.997; AGFI=.996; RMR=.056; NFI=.996). Los coeficientes alfa de las subescalas estaban entre .86 y .98. Se encontraron diferencias significativas en apoyo social percibido atribuibles al género y a tener pareja. Los resultados sustentan la validez del cuestionario MOS para la evaluación del apoyo social percibido por adultos mayores colombianos con dolor crónico.

Abstract Perceived social support refers to one's confidence that social support or resources are available if needed. It is related to health and quality of life in elderly, so it is recommended to be evaluated. The Social Support Survey MOS have been used but there is no evidence about its validity in Colombian ancient people with chronic pain. The aim of this study was to assess the factorial structure and reliability for the Social Support Survey MOS among a group of elderly people with chronic muskuloesqueletal pain; furthermore, differences between gender and married were investigated. 463 old people of different regions of Colombia were assessed with MOS and with a sociodemographic interview. Cronbach ranged between .86 y .98. Item correlations were higher than .60. The model of 4 correlated factors showed good fit (NFI= .997, AGFI= .996, RMR= .056 y GFI= .996), as shown by similar studies in other populations. Differences in social support perceived by gender and marital status were found. The results support the validity for the MOS to evaluate social support in ancient Colombian people with chronic muskuloesqueletal pain.

Anthropometric Index, Dietary Habits and Nutrient Intake of the Oldest-old Population Aged 95 and Over Living in Seoul / 대한지역사회영양학회지

The population aged 95 years and older in Seoul approximately increased to five-fold over the past 10 years, while nationwide rates increased to three-fold. In order to examine the dietary habit and nutritional status of oldest-old population living in Seoul, we recruited 87 subjects (25 males and 62 females) aged 95 years and older. The prevalence of underweight (BMI or = 25 kg/m2) were 18.2% and 18.2% in males, and 20.8% and 9.4% in females, respectively. In self-assessment of health, only 25.3% answered to be unhealthy. More males exercised regularly and reported a wide range of activities than females. The average of %Kcal from carbohydrate, protein and fat (C : P : F) was 64.9 : 13.8 : 21.2 in males and 68.1 : 14.2 : 17.7 in females. The average daily energy intake was 1,307 kcal in males and 1,304 kcal in females. More than 75% of subjects were taking under estimated average requirements (EAR) for vitamin B1, B2 & C and Ca. The average of mean adequacy ratio (MAR) was 0.66 in males and 0.70 in females, and 28.8% of males and 12.9% of females were in MAR < 0.50. Based on MAR, 32.0% of males and 14.5% females were classified as normal and 16.0% of males and 25.8% of females were classified as malnourished. Our subjects were taking more animal food, especially milk and its products, compared to those living, in rural areas. However, a significant proportion did not meet the EAR for vitamin B1, B2 & C and Ca.

Activity Groupings Reflecting Functional Characteristics Required in Daily Life in Institutionalized Dependent Females in the Old Old Elderly Group

Objectives: This study aimed to determine the activity groupings reflecting functional characteristics required in daily life for the institutionalized dependent females in the old-old elderly group, by examining the interrelationships of activities based on actual achievement characteristics. Methods: The participants were 697 dependent elderly living at welfare institutions in Japan and 344 old-old females were used for analysis. Factor analysis, based on Promax with the Kaiser Normalization method, was conducted using 74 activities of daily living (ADL) items to determine activity groups. Furthermore, whether each activity group could be classified into sub-groups was confirmed by applying factor analysis to the activities consisting of each activity group. Results: Four activity groups of lower extremity activities, manual activities, changing and holding posture activities, and upper extremity and dexterous manual activities were interpreted. Except for the manual activity group, these activity groups were classified into two sub-groups. Conclusions: These activity groupings were characterized by similarities of the body parts used in achievement and the difficulty of activity. The activity groupings obtained in this study are considered to be useful in ADL assessment focusing on evaluating functional characteristics of the dependent elderly.
