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: Fizzy soda water could be key to clean manufacture of flat wonder material: Graphene

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.

As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...

Im Focus: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...

Im Focus: Circular RNA linked to brain function

For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.

While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.

The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...

Im Focus: Scientists shine new light on the “other high temperature superconductor”

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.

Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
