Cardiovascular health status of taxi/for-hire vehicle drivers in the United States: A systematic review.

Most included studies used convenience samples, meaning the participants were not representative of all US taxi drivers. The majority of studies were cross-sectional, so they cannot prove that driving causes these health issues. Many studies relied on self-reported data for health conditions like hypertension and diabetes, which may be inaccurate. Only one study used a stratified random sampling method; the rest had potential for selection bias. The quality of evidence was low, with no randomized controlled trials included in the review. Findings may not generalize across different cities due to varying regulations and demographics.

The work was performed at Memorial Sloan Kettering Cancer Center. No specific funding source or conflicts of interest were declared in the provided text, though the authors note the lack of ethics review because no human subjects were directly involved in the review process itself.

Do not assume these rates apply to all taxi drivers. The evidence comes from small, non-representative convenience samples, and most studies were cross-sectional. High rates of hypertension and obesity were found in specific groups, but this does not prove that driving causes these conditions or that the findings are generalizable to the entire population of US drivers.
