The "key" evidence is the chart in article. This chart shows that Hispanics, Mexican, and Puerto Rican-origin individuals have faster increases in BMI in adolescence and in adulthood. In contrast, Chinese, Filipino, and other Asian individuals have lower BMI or slower BMI increases in adolescence and in adulthood while comparing to Whites. The reasons that cause the differences in BMI trajectories are parental education, welfare receipt before age 18, skip breakfast, mean screen time, mean physical activity, and current smoking. For instance, since the Mexicans like to smoke and always skip breakfast during morning, they have fast increases in BMI in adolescence and in adulthood.
