The study, of 5,500 seventh- and eighth-graders at 16 California schools, found that young Hispanic adolescents were more likely than other students to have ever used alcohol, cigarettes or marijuana. Asian students, meanwhile, had the lowest rates of substance use compared with Hispanic, white and African American students.
Moreover, the study found that some of the factors that seemed to influence kids' odds of substance use also varied by race and ethnicity.
Among Hispanic youth, it was personal factors that were linked to the risk of substance use -- including their confidence in their ability to "say no" and whether they believed drinking, smoking and drug use had more negative consequences.
In contrast, a wider range of factors was linked to Asian teens' relatively low rates of substance use -- not only those same personal-level factors but also respect for their parents and lower rates of substance use among their older siblings and peers.
The findings point to some important issues that could be addressed in substance-use prevention programs for middle school students, according to Regina A. Shih, Ph.D., and colleagues at the research organization RAND Corporation.
"Most interventions haven't really been tailored to be culturally appropriate," Shih explained. For example, "skills training," where kids learn how to resist pressure to smoke, drink or use drugs, could help address one of the personal factors that was connected to Hispanic students' higher rates of substance use.
Similarly, interventions that encourage positive parent-child communication and boost kids' sense of responsibility to their parents might help maintain lower rates of substance use -- and could be particularly effective for young Asian teens.
Shih said, however, that the researchers are not suggesting that such targeted efforts only be offered to students of certain ethnicities -- but that they could be widely applied in prevention programs to help the broadest range of kids possible. Many existing interventions target these types of personal factors and address adolescent and parent communication. "It is important for parents to be aware that many youth initiate substance use during the middle school years, and parents can help their teen make healthier choices by monitoring their activities and talking with them about these issues," Shih said.
Of all students in the study, 22 percent said they had ever used alcohol, 10 percent admitted to smoking at some point, and 7 percent reported marijuana use. In general, the odds of substance use were highest among Hispanic students, lowest among Asians and not statistically different between white and African American students.
When it came to drinking, for example, 26 percent of Hispanic students said they had ever tried alcohol, versus 21 percent of black students, 18 percent of whites and just below 10 percent of Asians.
When the researchers accounted for several other factors -- including gender and students' family structures -- Hispanic middle schoolers still had a higher probability, and Asian students still had a lower probability, of ever using cigarettes, alcohol or marijuana, compared with white students.
Using this large longitudinal sample, Shih's team will be able to continue to follow young adolescents over time to see which personal, family and school factors seem to predict the initiation or worsening of teens' smoking, drinking or drug use.
This study was funded by a diversity supplement and is part of a larger intervention project funded by the National Institute on Alcohol Abuse and Alcoholism (led by Dr. Elizabeth D'Amico).

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.
Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...
The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.
Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.
An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.
Endoscopes allow doctors to see into a patient’s body like through a keyhole. Typically, the images are transmitted via a bundle of several hundreds of optical...

Water molecules exist in two different forms with almost identical physical properties. For the first time, researchers have succeeded in separating the two forms to show that they can exhibit different chemical reactivities. These results were reported by researchers from the University of Basel and their colleagues in Hamburg in the scientific journal Nature Communications.
From a chemical perspective, water is a molecule in which a single oxygen atom is linked to two hydrogen atoms. It is less well known that water exists in two...
