To produce evidence on an association between the number of teeth and selected cardiovascular risk factors among an elderly population.
The study population comprised of 523 community-living elderly people who participated in the population-based Kuopio 75+ study. The data for each subject were collected using a structured clinical health examination, an interview and laboratory tests. Linear regression models were used to estimate adjusted mean values and confidence limits.
Edentulous persons and persons with a small number of teeth had lower serum HDL cholesterol and higher triglyceride, leucocyte and blood glucose levels and a higher body mass index (BMI) compared with subjects to a large number of teeth.
The study showed that, in the Finnish home-dwelling population aged 75 years or older, those with a large number of teeth were less likely to have cardiovascular risk factors such as a low serum HDL cholesterol level, a high triglyceride level and a high BMI than did subjects with a small number of teeth or who were edentulous.
To investigate whether anthropometric and body composition variables and handgrip strength (HS) were associated with physical function and independent daily living in 88-year-old Swedish women.
A cross-sectional analysis of 83 community-dwelling women aged 88 years who were of normal weight (n=30), overweight (n=29), and obese (n=24) was performed.
Body weight (Wt), height, waist circumference (WC), and arm circumference were assessed using an electronic scale and a measuring tape. Tricep skinfold thickness was measured using a skinfold calliper. Fat mass (FM) and fat-free mass (FFM) were measured using bioelectrical impedance analysis, and HS was recorded with an electronic grip force instrument. Linear regression was used to determine the contributions of parameters as a single predictor or as a ratio of HS to physical function (Short Form-36, SF-36PF) and instrumental activities of daily living (IADL).
Obese women had greater absolute FM and FFM and lower HS corrected for FFM and HS-based ratios (i.e., HS/Wt, HS/body mass index [BMI]) than their normal weight and overweight counterparts. After adjusting for physical activity levels and the number of chronic diseases, HS-based ratios explained more variance in SF-36PF scoring (R2, 0.52-0.54) than single anthropometric and body composition variables (R2, 0.45-0.51). WC, HS, and HS-based ratios (HS/Wt and HS/FFM) were also associated with independence in IADL.
Obese very old women have a high WC but their HS is relatively low in relation to their Wt and FFM. These parameters are better than BMI for predicting physical function and independent daily living.
objectively measured population physical activity (PA) data from older persons is lacking. The aim of this study was to describe free-living PA patterns and sedentary behaviours in Icelandic older men and women using accelerometer.
from April 2009 to June 2010, 579 AGESII-study participants aged 73-98 years wore an accelerometer (Actigraph GT3X) at the right hip for one complete week in the free-living settings.
in all subjects, sedentary time was the largest component of the total wear time, 75%, followed by low-light PA, 21%. Moderate-vigorous PA (MVPA) was
