Siblings’ bad habits brush off

16.01.2006


Brothers and sisters are more powerful role models than friends or parents when it comes to teenage drinking and smoking, research has shown.



Researchers from The University of Queensland and University of Washington have proved that tobacco and alcohol use by older siblings increases the odds of similar behaviour from younger siblings by three to five times.

University of Washington Sociologist Dr Abby Fagan studied the contributions and influence of parents, siblings and peers on teen drug use.


Dr Fagan used data from 1370 Brisbane teenagers, who’ve been part of one of the world’s longest running health studies -- the Mater-University of Queensland Study of Pregnancy.

The teenagers were interviewed between 1995 and 1997 at 14 years old and were asked about how often they drank and smoked and also about their family relationships.

On average, 13 percent of younger siblings reported smoking and 36 percent reported drinking, but rates increased when older siblings also reported substance use.

About 10 percent of younger siblings with non-smoking older siblings used tobacco, compared to 40 percent of those whose older siblings smoked.

Likewise, younger sibling alcohol use increased from 25 to 53 percent when older siblings reported drinking.

"The results underscore the need to include siblings, or at least address issues relating to sibling relationships and influences, in prevention efforts," Dr Fagan wrote in her study, published in the latest American Journal of Drug Issues.

"Currently, most tobacco and alcohol prevention programs target individuals for change or are aimed at improving parent-child communication and interactions.

"If siblings are more powerful role models than parents, however, sibling and their potential influences on each other should be a primary focus of intervention."

Maternal depression also had a significant effect on adolescent substance use.

Dr Fagan’s paper was co-written with UQ’s Mater Study founder, Professor Jake Najman.

The Mater Study was started in 1981 as a health and social study of 7223 pregnant women.

Im Focus: Powerful IT security for the car of the future – research alliance develops new approaches

The more electronics steer, accelerate and brake cars, the more important it is to protect them against cyber-attacks. That is why 15 partners from industry and academia will work together over the next three years on new approaches to IT security in self-driving cars. The joint project goes by the name Security For Connected, Autonomous Cars (SecForCARs) and has funding of €7.2 million from the German Federal Ministry of Education and Research. Infineon is leading the project.

Vehicles already offer diverse communication interfaces and more and more automated functions, such as distance and lane-keeping assist systems. At the same...

Im Focus: Molecular switch will facilitate the development of pioneering electro-optical devices

A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.

The development of new electronic technologies drives the incessant reduction of functional component sizes. In the context of an international collaborative...

Im Focus: LZH showcases laser material processing of tomorrow at the LASYS 2018

At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.

At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...

Im Focus: Self-illuminating pixels for a new display generation

There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?

At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
