Study design

Purpose of the study

Prevention

Allocation to intervention

Randomised controlled trial

Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)

Participants will be randomized based on a double-blind randomization schedule in which both researchers and participants will be unware of treatment group allocation

Methods used to generate the sequence in which subjects will be randomised (sequence generation)

Subjects will be stratified based on the age and BMI and, each stratum will be randomized by simple randomisation using a randomisation table created by computer software.

Masking / blinding

Blinded (masking used)

Who is / are masked / blinded?

The people receiving the treatment/s
The people administering the treatment/s

Statistical methods / analysis

The sample size calculation applies to CTx-II/creatinine, CTx-II/ CP II ratio, and COMP as the primary outcome variables. For CTX-II/ creatinine as well as CTx-II/ CPII a sample size of 24 is required to detect a 20% difference from baseline and a power of 80%. 25 subjects will be recruited for each group. For COMP as well as CP-II a sample size of 7 is required to detect a 20% difference from baseline.
Statistical analysis will be performed using IBM statistics software version 25 (Armonk, NY, USA). Participant characteristics will be presented as mean and standard deviation (mean, SD). Data will be analyzed by one-way ANOVA or Student’s t-test for variable with normal distribution and Kruskal-Wallis and Mann-Whitney U test for variable without normal distribution. Tukey’s t-test will be used to test whether difference from baseline for each treatment was different from zero, indicating that the mean changed over time.

Summary

Brief summary

Osteoarthritis (OA) is the most common type of joint disease, contributing to progressive pain and disability in the elderly. In New Zealand, OA is affecting 10.2% of the adult population and the incidence escalating with age, and obesity causing the large health-related quality of life loss in NZ. The prevalence of OA is generally higher in women compared to men, as the incidence tend to consistently increase, particularly following menopause, likely due to losing the protective effect of estrogen on joint tissue.
There is no cure for OA and the conventional treatment only used for symptom management. Oil extract from the Greenshell mussel (GSM), a native New Zealand shellfish, has been effective to reduce OA symptoms. A recent animal study showed flash-dried powder from whole GSM meat has preventive effects against the early-stage of metabolic-associated OA. In this study adding GSM powder into the diet of rats actively developing diet-induced OA reduced the cartilage degradation marker. Results from this preliminary study support the potential for an intervention study feeding human subjects with the whole meat GSM powder in order to attenuate the development of OA in a high-risk population. 
Therefore, this study aims to evaluate the effects of flash-dried whole meat GSM powder (3 g/day) or identical placebo for 12 weeks on cartilage and bone biomarkers, inflammation, body composition, health parameters, knee function and joint pain in healthy overweight/obese postmenopausal women. Data will be collected using questionnaires to assess the demographic detail, dietary intake, knee function, and pain. Blood (20 ml) and spot urine samples will be collected at the beginning, week 6 and week 12 to measure the biomarkers of cartilage, bone, and inflammation. Dual-energy X-ray absorptiometry (DXA) will be used at the beginning and week 12 for body composition (fat/lean ratio) measurement.
