Claim
correlational

In university students in Jordan, body pain is common and strongly linked to poor sleep and anxiety, but not directly to how much dairy calcium people eat, meaning pain may be more related to stress and sleep than to nutrient levels.

What Would Prove This

Per GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this claim, ordered from strongest to weakest.

1
Systematic Reviews & Meta-Analyses

Whether insomnia and anxiety independently predict musculoskeletal pain in young adults, independent of calcium intake or other nutritional factors.

A systematic review and meta-analysis of longitudinal studies measuring insomnia (ISI), anxiety (HADS), and musculoskeletal pain (≥3 sites) in adults aged 18–25, assessing pooled effect sizes while adjusting for calcium intake, BMI, physical activity, and sleep hygiene.

2
Randomized Controlled Trials

Whether reducing insomnia or anxiety directly reduces musculoskeletal pain in young adults, independent of calcium intake.

A double-blind RCT of 200 university students with MSP and insomnia/anxiety (ISI ≥15, HADS-anxiety ≥11) randomized to CBT-I, CBT for anxiety, or waitlist control for 8 weeks, measuring change in MSP intensity and number of painful sites as primary outcomes.

3
Cohort Studies

Whether insomnia and anxiety predict the development of new musculoskeletal pain in young adults over time.

A prospective cohort study following 1000 university students aged 18–22 for 2 years, measuring ISI and HADS-anxiety quarterly and assessing incident MSP (≥3 painful sites) at 12 and 24 months, adjusting for baseline pain, calcium intake, and physical activity.

4
Case-Control Studies

Whether individuals with chronic musculoskeletal pain have higher prior levels of insomnia and anxiety compared to matched controls.

A case-control study comparing 12-month history of insomnia (ISI ≥15) and anxiety (HADS ≥11) in 200 university students with chronic MSP (≥3 sites for ≥3 months) versus 200 matched controls without MSP, using structured interviews and validated scales.

5
Cross-Sectional Studies
In Evidence

Whether musculoskeletal pain co-occurs with insomnia and anxiety in a population at a single point in time.

A cross-sectional survey of 1000 university students measuring ISI, HADS-anxiety, and MSP simultaneously using validated tools, as performed in this study.
