Abstract Objectives To assess the dietary intakes and diet
quality of menopausal women relative to premenopausal women,
and to determine whether their diets are compatible with
reducing risks of cardiovascular disease (CVD) and
osteoporosis. Design Cross-sectional study using 3-day food
records and anthropometric measurements. Subjects Thirty
apparently healthy, nonoestrogen using and nonsupplemented
women menopausal since 3-5 years and 30 well-matched
premenopausal women. Outcome measures Nutrient intakes, diet
nutrient density, body mass index (BMI), waist
circumference, waist-to-hip ratio and serum oestradiol.
Results Energy intake and body weight of pre- and
postmenopausal women were comparable. Their BMI, waist
circumference and waist-to-hip ratios were within healthy
ranges. The diet of postmenopausal women was compatible
(less total lipids and saturated fatty acids; more fibres,
antioxidant vitamins and potassium) with North American
nutritional recommendations linked to cardiovascular health.
Their dietary iron intakes exceeded their reduced
physiological need, which may jeopardize their
cardiovascular system. Their calcium and vitamin D intakes
were far below recommendations for healthy bones. Five other
nutrients were also suboptimal. Phosphorus intake (high in
both groups) correlated with dietary proteins, sulphur amino
acids and calcium. Conclusions The diet of the
postmenopausal women studied were more compatible with
national nutritional recommendations than that of
premenopausal controls. However, these postmenopausal women,
not taking hormone replacement therapy (HRT) and having
inadequate dietary calcium and vitamin D intakes, may be at
increased risk of osteoporotic fracture later in life. More
studies on CVD risk inherent to body iron accumulation
involving a large number of postmenopausal women are
warranted before planning public health measures regarding
dietary iron intake.
