Prevalence of caries was the same in community-dwelling and NHR
patients.
Conclusions:
Socioeconomic determinants such as education,
profession and place of living were determinants of OHS. NHS
should reimburse oral healthcare in order to prevent poor OHS in
older people.

Objectives:
Time spent in moderate-to-vigorous activity (MT) in
young adults predicts daily caloric expenditure (CE). Conversely CE
is best predicted in older adults by time spent in light activity (LT).
We examined highly active older adults to examine the biggest
contributors to energy expenditure in this population.
Methods:
54 community dwelling men and women
>
65 years
of age (mean 71.5 years) were enrolled in this cross-sectional
observational study. All were members of the Senior’s Whistler
Ski Team and all met current American guidelines for physical
activity. Activity levels (ST, LT and MT per day) were recorded with
accelerometers worn continuously for 7 days. CE was measured
using accelerometry, galvanic skin response, skin temperature
and heat flux (SenseWear armband). Significant variables were
then entered into a stepwise multivariate linear model containing
activity levels, age and gender.
Results:
The average daily non-lying sedentary time was 564
±
13
minutes (9.4
±
0.2 hours) per day. The main predictors of
higher CE were time spent in moderate-to-vigorous activity
(MT, Standardized
b
0.360
±
0.086, p
<
0.001) and male gender
(Standardized
b
1.421
±
0.171, p
<
0.001). A model containing only
MT and gender explained 66 percent of the variation in CE. An
increase in MT by one minute per day was associated with an
additional 25 calories expended in physical activity.
Conclusions:
The relationship between activity intensity and CE in
athletic seniors is similar to that observed in young adults. Active
older adults still spend a substantial proportion of the day engaged
in sedentary behaviours.
