Outcome measures
Primary outcome
Calcium intake from food, supplement and medication was obtained from a food
questionnaire. The attendant of the client will fill in this questionnaire. In
this questionnaire there will be asked how many cups of food products with
calcium the patient eats e.g. milk, cheese and yoghurt. These cups will be
converted in grams calcium.
The quality of the calcaneus (heel bone) will be measured with a Lunar Achilles
Insight, which is a portable device that measures the bone quality of the heel
with ultrasonometry. Evidence supports the value of densitometry at the heel as
the optimum peripheral site for fracture risk assessment, due to the heel's
easy accessibility, metabolically active bone and high trabecular content.
Secondary outcome
The secondary variability*s are the age, the level of development, the
mobility, sort of residence and guidance of the client. The level of
development is subdivided in profound mental retardation (IQ below 20), severe
mental retardation (IQ is 20 - 34), moderate mental retardation (IQ is 35 - 49)
and mild mental retardation (IQ is 50 - 69).
The mobility is subdivided in be able to stand or walk and not be able to stand
or walk.
The sort of residence is subdivided in living in a community, living in a
private apartment in a community, in a family replacement residence.
The guidance is subdivided in guided but independent living or independent
living.
With these variability*s we want to answer the question if there is a relation
between the calcium intake and the secondary variability*s.
Background summary
In this study we determine the calcium intake from food, supplements or
medication in postmenopausal women with an intellectual disability (ID). We
also determine the prevalence of osteoporosis in the same group.
Osteoporosis is characterized by low bone mass and micro architectural
deterioration of bone tissue, which leads to an increase in bone fragility with
a resultant susceptibility to fracture.
The factor that leads to osteoporosis in women is also because of the decrease
of estrogens in the menopause. Therefore, the Dutch federation of general
practitioners (Nederlandse Huisartsen Genootschap Standard) gives the advice to
eat daily 1000 to 1200mg of calcium. It seems to be that Dutch women at the age
of 50 years and older, eat 100 to 250mg less calcium than is advised.
Little is known about the prevalence of the calcium intake in postmenopausal
women with an intellectual disability. But it is known that the prevalence of
osteoporosis is higher in women with an ID. Women with physical disabilities
that impair mobility have many risk factors for osteoporosis. Such women often
are non-ambulatory, frequently taking medications that increase the risk of
osteoporosis, and may have lifestyles that do not offer optimal exposure to
sunlight, which can predispose to vitamin D deficiency.
Study objective
We examine whether the calcium intake from food in postmenopausal women with an
ID suffice to the quantity calcium intake that is advised by the NHG-standard.
If the conclusion of this study will be that the population is eating less
calcium than is advised, a simple advise and intervention can follow.
Study design
This study has a cross-sectional observational design, where there will be no
interventions.
Study burden and risks
The attendant of the client will answer the food questionnaire. It will take at
the very most 30 minutes. This depends on how acquainted the attendant is with
the food pattern of the client.
The measurement of the bone quality with the Lunar Achilles Insight will take
five minutes per client. The Lunar Achilles Insight is non-invasive and free
from radiation. The testing is simple and fast and is does not give discomfort
to the client. The measurements can also be executed at feet that are mildly
dysmorfic. The measurements are less suitable for people with severe motor
disabilities or severe dysmorfic feet. These measurements can be invalid.
There are no medical risks for the client. When the conclusion is that the
client has a reduced intake of calcium or a reduced bone quality, advise about
interventions and further research will be giving to the permanent doctor of
the client.
