(HealthDay News) — Mobile phone use for making or receiving calls was significantly associated with a higher risk for new-onset hypertension, according to a study published online in the European Heart Journal: Digital Health.
Ziliang Ye, from Southern Medical University in Guangzhou, China, and colleagues examined associations of mobile phone use for making or receiving calls and use frequency with new-onset hypertension in the general population. The analysis included data (median follow-up, 12.0 years) from 212,046 participants in the UK Biobank without prior hypertension.
The researchers found that compared with mobile phone nonusers, a significantly higher risk for new-onset hypertension was seen in mobile phone users (hazard ratio [HR], 1.07). Compared with those with a weekly usage time of mobile phones for making or receiving calls <5 minutes, there was a significantly higher risk for new-onset hypertension for participants with a weekly usage time of 30 to 59 minutes (HR, 1.08), 1-3 hours (HR, 1.13), 4-6 hours (HR, 1.16), and more than 6 hours (HR, 1.25). The highest risk for new-onset hypertension was seen for participants with both high genetic risks for hypertension and longer weekly usage time of mobile phones.
“It’s the number of minutes people spend talking on a mobile that matter for heart health, with more minutes meaning greater risk,” a coauthor said in a statement. “Years of use or employing a hands-free set-up had no influence on the likelihood of developing high blood pressure.”
