A 2012 randomised controlled trial of 360 pregnant women found that women who attended a workshop addressing dietary behaviours, gestational weight gain awareness, physical activity, smoking and breastfeeding were significantly more likely to report increased consumption of fruit and vegetables, a higher diet quality score and physical activity compared with women who received usual care [45]
We set those thresholds so that we assign roughly a third of 30-day periods within each clinical group to each functional impairment level (low, medium, or high)
The American Lung Association also advocates additional research but argues smoke is harmful to lung health and that marijuana has been shown to contain many of the same toxins, irritants and carcinogens as tobacco smoke. Marijuana may also be more harmful to the lungs because of how people smoke it, Rizzo said
