A recent study published in the American Journal of Physiology found that prenatal exposure to thirdhand smoke can have as serious or even more negative impacts on an infant's lung development than postnatal or childhood exposure. Pregnant women should take precautions to avoid homes and places where thirdhand smoke is likely to be found.
A University of Missouri study found that teaching refusal skills can help minority youths resist tobacco use, particularly those from American Indian or Alaska Native (AI/AN) communities. These skills are crucial in countering the high rates of smoking among AI/AN youths, who have a greater lifetime smoking rate than other racial groups.
A study by Wake Forest Baptist Medical Center found that 40.3% of college students reported smoking tobacco from a hookah, while 17.4% were current users. Hookah smokers mistakenly believed it to be safer than cigarette smoking, with some even using hookahs as their first tobacco product.
A Spanish study reveals that babies who sleep with their smoker parents exhibit three times higher nicotine levels than those in separate rooms. The researchers found that ventilating bedrooms does not effectively reduce toxin exposure from passive smoking.
An Australian study found that 78% of school-aged children slept through a smoke alarm sounding for 30 seconds. The study highlights the importance of child evacuation in domestic fires, as only half of waking children recognized the alarm's sound. Younger children (5-10 years old) are significantly more at risk.
A study published in Pediatrics found that pregnant non-smokers exposed to second-hand smoke have a higher risk of delivering stillborn babies or babies with congenital birth defects. Passive smoking increased the risk of stillbirth by nearly one-quarter and was linked to a 13% increased risk of congenital birth defects.
Researchers found that text messaging is at least as effective as handheld devices in measuring smoking urges and resisting cravings, with tailored interventions tailored to individuals' response-inhibition capacities. The study also identified key brain regions involved in response inhibition.
