In this study we used a model to predict of the Iranian people aged height from age, shin length and forearm length. Methods: A total 165 aged people ≥60 years were randomly selected based on medical record number of about 800 eligible older people who lived in Kahrizak Charity Foundation. Standing height, shin length and forearm length were measured. Data from 99 participants were used to creat a predicting multivariate linear regression model for estimation of standing height of older men and women. The data of the rest 66 participants were used for models testing. Result: The following equations were created: Men height = 78.928+ (1.430× shin length) + (0.817×forearm length)-(0.176×age) The height of women = 71.694+ (1.414×shin length) + (1.084× forearm length)-(0.277× age) R 2 were calculated as 0.63 for men and 0.52 for women. Error of estimation was +0.44 cm and it was-0.16cm and +1.09cm for men and women respectively. Estimated heights were not significantly different from standing statures. Conclusion: height was predictable from shin length and for forearm lengths and also age with a relatively small error in the estimation among Iranian older people. The error of model is more in women than men.

Methods: A total of 247 Kahrizak Charity Foundation (KCF) residents aged 365 years were followed up for approximately 39 months. At the baseline, the questionnaires of Barthel Index (BI), Mini-Mental State Examination, Geriatric Depression Scale, Mini Nutritional Assessment and Norton Index was given. Medical history was recorded and anthropometric values were also measured at the baseline. Fasting blood samples were collected at baseline. Mortality and its causes were recorded during the study. Results: A total of 30% (74) of participants died during the study. The variables that had a significant association with mortality in the Cox regression hazard model were entered into the principal components analysis (PCA). The older people's mortality index (OPMI) was developed by four variables extracted from PCA, including BI, age, hemoglobin and mid-arm circumference. Cut-points of these components were calculated using ROC curve analysis. Based on neural network analysis, there was no significant difference in relative importance of OPMI components. OPMI was correlated to mortality (r = -0.351, P = 0.000) and survival (r = -0.355, P = 0.000). OPMI score was defined as the number of adverse predictors present. An increasing hazard ratio for mortality was observed from scores 1 to 4 (2.10, 4.56, 7.12 and 13.85, respectively). Our suggested model could predict mortality in KCF residents well. The new developed model could be a practical, easy and non-expensive index for mortality prediction in elderly care facilities. Geriatr Gerontol Int 2012; 12: 36-45.

The Nutritional Form for the Elderly (NUFFE) is an instrument for nutritional screening that is easily applicable without special nutritional training. →What this article adds: The developed Persian version of NUFFE is a valid and reliable tool in nutritional screening among Iranian elderly nursing homes residents.

Design Cross-sectional study. Setting Participants were recruited from the Kahrizak Charity Foundation (KCF). Measurements Nutritional and ability status were examined using the MNA and the Barthel Index (BI). Participants were divided according to MNA (≤23.5 and > 23.5). Results Two hundred and thirty-five ≥ 60-year-old

Materials and Methods: In 28 diabetic patients and 22 age and sex-matched healthy adults, the carotid intimae-media thickness was measured using Doppler ultrasound. Blood glucose, total cholesterol, triglycerides, LDL and HLD choles-terol level were measured after overnight fasting and again 4 hours after a standard high-fat meal. Results: The carotid intimae- ...
