In a surprising finding, researchers have discovered that in war-torn Yemen, young people who don't smoke are actually more likely to have anemia than those who do. This "healthy smoker paradox" challenges the conventional wisdom that smoking always leads to better health. Instead, the study suggests that in extreme poverty, socioeconomic status may play a bigger role in determining health outcomes. The researchers found that students from lower-income backgrounds and females were more likely to have anemia, regardless of whether they smoked or not. This unexpected result highlights the complex interplay between social and biological factors in shaping health outcomes, particularly in crisis situations.
