Taxi drivers and modifiable health behaviors: Is stress associated?
Sheena Mirpuri, Kristen Riley, Francesca Gany
PMID 34366310WHAT IT FOUND
Most taxi drivers had poor nutrition and low physical activity.
Stress predicted sleep disturbances and smoking, but not diet or exercise. These behaviors mostly occurred independently, suggesting separate interventions are needed for each problem rather than a single stress-reduction program.
Key findings
01Perceived stress significantly predicted sleep disturbances and was related to smoking odds, but did not predict physical activity or nutrition.
02Health behaviors such as physical activity, nutrition, and sleep largely occurred independently of one another, except for a link between sugar consumption and smoking.
03Drivers reported low fruit and vegetable intake and minimal physical activity, with almost half reporting no moderate activity in the past month.

What it does not show
The study used a convenience sample of male drivers, which limits generalizability to female drivers or the broader population. The cross-sectional design prevents determining whether stress causes health behaviors or vice versa. Data relied on self-reports, which may be inaccurate due to social desirability or recall bias. The sample was collected during a period of economic instability for the taxi industry, which may have influenced stress levels. Night shift drivers were underrepresented, potentially missing sleep issues specific to that group.
The easy way to misread this
Do not assume that reducing stress will improve all health behaviors in this population. Stress predicted sleep and smoking but not diet or physical activity, and most behaviors occurred independently.
