Health behaviour research, explained
20 open-access health behaviour studies, each with a flashcard deck and a quiz.
- Does the WHO GPAQ match a wearable for activity and sitting?
In 95 adults, GPAQ moderately matched Actigraph MVPA (r=0.48) but poorly captured sitting time (r=0.19), with a 349 min/day sedentary gap.
- Which COVID NPIs actually lowered Rt?
Across 130 countries, school closure and internal movement limits consistently tracked lower SARS-CoV-2 Rt; other NPIs were more conditional or inconclusive.
- Healthy lifestyle and multimorbidity risk
Healthier lifestyle scores tracked lower CVD and diabetes risk and lower multimorbidity transitions.
- Does patient-centered care help people with many conditions feel better?
Among 216 Dutch primary-care patients with multi-morbidity, patient-centered and co-created care tracked with better physical/social well-being and higher care satisfaction.
- How did fear and precautions change early in the 2009 flu pandemic?
As the 2009 swine flu spread, Americans felt more likely to catch it, yet their interest in vaccines and information seeking fell, tracking the decline in news coverage rather than the actual risk.
- Does a step-log app keep people tracking activity?
In 10,000 Steps members, a smartphone iStepLog app preserved daily logging and high step counts versus matched controls whose logging fell.
- Web program increased older adults’ measured activity in a trial
A Dutch RCT found a web-based intervention raised daily activity ~46% and improved weight and HbA1c markers in inactive 60–70-year-olds.
- Smart-T smoking EMI app
A tailored smartphone EMI for low-SES smokers was highly acceptable and achieved 20% CO-confirmed abstinence at 12 weeks in a small sample.
- Facebook team walking RCT
A 50-day team social-network pedometer program boosted walking/MVPA during the intervention, but gains were not maintained 3 months later.
- Child-care diet/activity RCT and zBMI
A seven-month child-care nutrition and activity intervention significantly reduced children's zBMI versus control centers.
- Do ensemble COVID forecasts beat single models?
Over 52 weeks and 32 European countries, a weekly multi-model ensemble beat most component models for cases and deaths, with median combining outperforming means.
- Do cigarette smokers sleep worse than nonsmokers in central China?
Among 26,282 Hunan residents, smokers (25.3%) scored worse on almost every PSQI domain and more often had sleep disturbance (32.7% vs 24.5%).
- What is left 1 year after mostly non-severe COVID-19?
Among 120 Wuhan survivors (~87% non-severe) followed a median 314.5 days, sleep problems, dyspnea, fatigue, joint pain, anxiety/depression, and diffusion impairment remained common.
- Does sarcopenia go with rotator-cuff tendon trouble?
In 112 older adults, sarcopenia tracked more shoulder pain, thicker supraspinatus tendons (β=0.447), and lower tendon-to-muscle echogenicity, but not more rotator-cuff tears.
- How much does Long COVID after mild illness hurt quality of life?
In 112 Long-COVID patients (mostly mild acute COVID), SF-36 physical scores were markedly below Swiss norms; fatigue and concentration problems dominated.
- Did India’s tobacco epidemic peak and recede?
Across NFHS rounds, age-standardized tobacco use in Indian men rose 32% from 1998-99 to 2005-06 (27.90% to 36.81%) then fell 26% by 2015-16 (to 27.31%), while women’s use declined throughout—yet 2015-16 levels still looked like 1998-99, with huge state gaps.
- Who uses smokeless tobacco in India’s LASI sample?
Among 65,561 LASI adults, 38% had used any tobacco; 22.8% ever and 20.4% currently used smokeless tobacco, with higher use in rural, male, poorer, ST, and informal/agricultural work.
- Do diet and sleep disorders combine to raise death risk?
In 23,212 NHANES adults, low Mediterranean-diet scores plus sleep disorders raised all-cause (HR 2.16) and CVD (HR 2.68) mortality, with a significant CVD interaction.
- What do global experts agree on about Long COVID?
A 179-person, 28-country Delphi reached 187 consensus statements—strongest on diagnosis and research needs, including children and biomarkers.
- Does meth break male and female prefrontal neurons the same way?
In 94 F344 rats, males and females self-administered similar meth (≈28–29 mg/kg over 21 days) and kept seeking at 30 days, but VGCC calcium spikes fell in males and rose in females after short withdrawal.
