Study summary

The process of bone remodeling exhibits pronounced diurnal pattern that is important for bone health. A balanced rate of bone resorption is required to maintain bone health, a balance that can be disturbed during the lifecycle to effect net rate of formation (as occurs during growth and development to adulthood) or net resorption (as occurs, for example, during the menopause).The research to be undertaken investigates the pluripotent effect of dairy-based products on the regulation of the diurnal process of bone metabolism in post-menopausal women at risk of osteoporosis.

Read the detailed description

Study Design: A block randomised, cross-over design of 24h rates of bone turnover in healthy, post-menopausal women with osteopenia receiving either a milk-based protein supplement (MBPS) or isoenergetic placebo control (PLACEBO).

Participants: 16 Post-menopausal women with osteopenia as determined by site-specific bone mineral density BMD (DXA) diagnosed and screened by a clinician and for dietary intake of calcium and Vit D by a clinical dietitian.

Subject screening (clinical examination) and dietary intake of calcium and Vit D (by food frequency questionnaire) will precede the experimental protocol.

Experimental protocol and data collection:

Subjects will attend for a 2 day and 2 night (overnight) residence equipped to conduct residential human trials.

The subjects' programmed protocol is as follows;

  1. Arrive @ 17:00h with overnight bag;
  2. Empty bladder and then provide and retain urine samples for the duration of the stay (assisted collection by researchers);
  3. Consume a standardised evening meal (pre-prepared by the research dietitian) and then relax reading/watching films etc;
  4. At 20:00h a research nurse will insert a cannula into a superficial arm vein and a blood draw (5ml) will be taken and processed for later analysis;
  5. Further blood draws (5ml) will be taken at 22:00h, 2300h, 2400h,0100h and 0200h and the cannula withdrawn;
  6. At 22:00h consume either placebo control (PLACEBO) (day 1) OR supplement (MBPM)(day 2) - or vice versa - in randomised order.
  7. Retire to bedroom;
  8. Consume a standardised breakfast and lunch (pre-prepared by the research dietitian) whilst living in and around the University grounds (i.e. in close proximity to ensure 24h urine collection is complete);
  9. Repeat from 2 above to end of 2nd day.

Study arms

  • Placebo comparator
    PLACEBO

    Intervention: Dietary Supplement: PLACEBO A group of subjects ingesting a liquid beverage (0.3g per kg body mass ; 1.2kcal/kg body mass) at 10:00pm, 3h post-absorptive of a standardised evening meal. Samples for the measurement of biomarkers of change in the rate of bone turnover appearing in the blood to be collected for the immediate 4h, and excreted in urine, 24h post-ingestion

    Dietary Supplement: PLACEBO

  • Active comparator
    Milk-based protein matrix

    Intervention: Dietary Supplement: MBPM A group of subjects ingesting a liquid beverage (0.3g per kg body mass ; 1.2kcal/kg body mass) at 10:00pm, 3h post-absorptive of a standardised evening meal. Samples for the measurement of biomarkers of change in the rate of bone turnover appearing in the blood to be collected for the immediate 4h, and excreted in urine, 24h post-ingestion

What researchers measure

Primary outcomes

  1. Bone turnover

    A balance of the difference between the magnitude and time course of the acute change (0-4h) in serum C-terminal telopeptide of type 1 collagen (CTX) in ng/mL, a measure of bone resorption, and procollagen type 1 amino-terminal propeptide (P1NP) in ng/ml, a measure of bone formation and diurnal change in bone resorption measured by 24h urinary excretion of deoxypyridinoline (Dpd), a marker of bone resorption, normalised to creatinine. Units nmolDPD/mmolCr

    Time frame: Pre-ingestion and1,2,3 and 4hours post-ingestion (serum) and Pre-ingestion to +24hour post-ingestion (urine)

Secondary outcomes

  1. Change in regulator of bone metabolism - PTH

    The magnitude and time course of the acute change (0-4h) in serum parathyroid hormone (PTH) measured in pmol/L
