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: Neutron star merger directly observed for the first time

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event

On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...

Im Focus: Breaking: the first light from two neutron stars merging

Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.

Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....

Im Focus: Smart sensors for efficient processes

Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).

When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...

Im Focus: Cold molecules on collision course

Using a new cooling technique MPQ scientists succeed at observing collisions in a dense beam of cold and slow dipolar molecules.

How do chemical reactions proceed at extremely low temperatures? The answer requires the investigation of molecular samples that are cold, dense, and slow at...

Im Focus: Shrinking the proton again!

Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.

It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...
