From the 30 October 2014 UCLA press release

In addition to providing other potential benefits to public health, all of those tweets and Facebook posts could help curb the spread of HIV.

Although public health researchers have focused early applications of social media on reliably monitoring the spread of diseases such as the flu, Sean Young of the Center for Digital Behavior at the University of California, Los Angeles, writes in an October 29th article in the Cell Press journal Trends in Microbiology of a future in which social media might predict and even change biomedical outcomes.

“We know that mining social media will have huge potential benefits for many areas of medicine in the future, but we’re still in the early stages of testing how powerful these technologies will be,” Young said.

With the right tools in place, he says, social media offers a rich source of psychological and health-related data generated in an environment in which people are often willing to share freely.

His recent work on Behavioral Insights on Big Data (BIBD) for HIV offers the tantalizing possibility that insights gleaned from social media could be used to help governments, public health departments, hospitals, and caretakers monitor people’s health behaviors “to know where, when, and how we might be able to prevent HIV transmission.”

Young details a social-media-based intervention in which African American and Latino men who have sex with men shared a tremendous amount of personal information through social media, including when or whether they had ‘come out,’ as well as experiences of homelessness and stigmatization. What’s more, they found that people who discussed HIV prevention topics on social media were more than twice as likely to later request an HIV test.

In the context of HIV prevention, tweets have also been shown to identify people who are currently or soon to engage in sexual- or drug-related risk behaviors. Those tweets can be mapped to particular locations and related to actual HIV trends.

What’s needed now is the updated infrastructure and sophisticated toolkits to handle all of those data, Young said, noting that there are about 500 million communications sent every day on Twitter alone. He and a team of University of California computer scientists are working to meet that challenge now.

Although privacy concerns about such uses of social media shouldn’t be ignored, Young says there is evidence that people have already begun to accept such uses of social media, even by corporations looking to boost profits.

“Since people are already getting used to the fact that corporations are doing this, we should at least support public health researchers in using these same methods to try and improve our health and well being,” he said. “We’re already seeing increased support from patients and public health departments.”

Shared psychological characteristics that are linked to aggression between patients with Internet addiction and those with alcohol dependence | Full Text Reports….

Background
Internet addiction (IA) is considered as one of behavioral addictions. Although common neurobiological mechanisms have been suggested to underlie behavioral addiction and substance dependence, few studies have directly compared IA with substance dependence, such as alcohol dependence (AD).

Methods
We compared patients with IA, AD, and healthy controls (HC) in terms of the Five Factor Model of personality and with regard to impulsiveness, anger expression, and mood to explore psychological factors that are linked to aggression. All patients were treatment-seeking and had moderate-to-severe symptoms.

Results
The IA and AD groups showed a lower level of agreeableness and higher levels of neuroticism, impulsivity, and anger expression compared with the HC group, which are characteristics related to aggression. The addiction groups showed lower levels of extraversion, openness to experience, and conscientiousness and were more depressive and anxious than the HCs, and the severity of IA and AD symptoms was positively correlated with these types of psychopathology.

Conclusions
IA and AD are similar in terms of personality, temperament, and emotion, and they share common characteristics that may lead to aggression. Our findings suggest that strategies to reduce aggression in patients with IA are necessary and that IA and AD are closely related and should be dealt with as having a close nosological relationship.

[Press Release] Brain Scans Show We Take Risks Because We Can’t Stop Ourselves

Major implications in concepts as free will, sin, justice, mental illness, government/medical “intervention”…..

From the 4 February 2014 University of Texas at Austin press release

AUSTIN, Texas — A new study correlating brain activity with how people make decisions suggests that when individuals engage in risky behavior, such as drunk driving or unsafe sex, it’s probably not because their brains’ desire systems are too active, but because their self-control systems are not active enough.

This might have implications for how health experts treat mental illness and addiction or how the legal system assesses a criminal’s likelihood of committing another crime.

When these brain regions (mostly associated with control) aren’t active enough, we make risky choices. Z-statistic corresponds to predictive ability, yellow being the most predictive regions. Image: Sarah Helfinstein/U. of Texas at Austin.

Researchers from The University of Texas at Austin, UCLA and elsewhere analyzed data from 108 subjects who sat in a magnetic resonance imaging (MRI) scanner — a machine that allows researchers to pinpoint brain activity in vivid, three-dimensional images — while playing a video game that simulates risk-taking.

The researchers used specialized software to look for patterns of activity across the whole brain that preceded a person’s making a risky choice or a safe choice in one set of subjects. Then they asked the software to predict what other subjects would choose during the game based solely on their brain activity. The software accurately predicted people’s choices 71 percent of the time.

“These patterns are reliable enough that not only can we predict what will happen in an additional test on the same person, but on people we haven’t seen before,” said Russell Poldrack, director of UT Austin’s Imaging Research Center and professor of psychology and neuroscience.

[Press release] Is smoking cannabis and driving the new drinking and driving?

From the [undated December] Ontario Centre for Addiction and Mental Health

Use of prescription, over-the-counter medications also of concern in CAMH’s latest Ontario Student Drug Use and Health Survey (OSDUHS)

December 11, 2013 – Alcohol consumption and smoking among Ontario students in grades 7-12 is at an all-time low; however recreational use of over-the-counter drugs is on the rise.  Prescription drug misuse and driving after using drugs also remain elevated according to the 2013 Ontario Student Drug Use and Health Survey (OSDUHS) released today by the Centre for Addiction and Mental Health (CAMH). The survey of 10,272 students from across Ontario is Canada’s longest-running systematic study of alcohol and other drug use among youth, and one of the longest-running surveys in the world

Over-the-counter and prescription drugs

The survey shows one in eight (representing 120,000 middle and high school students in Ontario) reported taking a prescription opioid pain medication recreationally in the last year, and the majority of these students said that they got the drugs from home. About one per cent (representing 13,500 students) reported using stimulant drugs (used to treat ADHD) without a prescription. There was an increase in the number of students who reported using over-the-counter cough medication to “get high,” with over 94,000 students (about 10%) engaging in this behaviour. This was the only drug to show an increase in recent years. One in six high school students reported symptoms of a drug use problem; this represents 132,700 students in grades 9-12.

Substance use and driving

Eighteen per cent of students reported being a passenger in a car driven by someone who had been drinking alcohol. Four per cent of students with a G-class driver’s license said they had driven a vehicle within one hour of consuming two or more drinks – this is an estimated 12,700 adolescent drivers in Ontario.

Cannabis smoking and driving levels were even higher. Despite the serious impact that smoking cannabis can have on psychomotor skills and the ability to drive safely, one in ten licensed students reported driving a car within one hour of smoking cannabis. This represents 31,500 adolescent drivers in Ontario. Fourteen per cent of students reported being a passenger in a car where the driver had been using drugs.

“The number of students who report using cannabis and driving has remained the same in recent years which tells us that students do not take the potential dangers of driving while under the influence seriously,” said Dr. Robert Mann, CAMH Senior Scientist and OSDUHS Principal Investigator.  “The public health messages around the dangers of drinking and driving seem to have had an impact on our youth but the same can’t be said for cannabis use, which is worrisome.”

Drinking

Alcohol use among Ontario students reached an all-time low with 50 per cent (representing 483,900 students) reporting drinking alcohol in the past year. “Though the overall decline shows promise, we see that the kids who are drinking are doing so in dangerous ways,” added Dr. Mann. “One in five (representing 193,400 students) reports binge drinking at least once in the past month and a similar percentage report blacking out on at least one occasion when drinking alcohol in the past year. Eight per cent report being injured or injuring someone else while they had been drinking.”

New this year

New in this year’s OSDUHS are questions on the use of waterpipes and electronic cigarettes.  Almost 10 per cent (representing 88,400 students) reported smoking tobacco through a waterpipe in the past year. About 15 per cent of high school students (representing 99,800 students) reported smoking electronic cigarettes in their lifetime. For the first time the survey asked students whether they had used synthetic cannabis, commonly known by street names, “K2” or “spice.” Two per cent – representing over 17,000 students – had tried the drug.

“These new numbers give us some insight into the use of alternative and emerging drugs among young people,” said Dr. Hayley Hamilton, CAMH Scientist and Co-Investigator on the OSDUHS. “We see that while cannabis use among students is holding steady since our last survey at around one quarter of students, this new synthetic form has emerged and we will want to track its prevalence in future surveys. The same holds for smoking – while the rate of students smoking has leveled off over the past few years, we see that youth are still smoking cigarettes and tobacco, but in alternate ways.”

Regional differences

  • Students in Toronto and Western Ontario reported the nonmedical use of opioid prescription pain medication at higher rates than the rest of the province (15 per cent and 13 per cent respectively)
  • Students in the north were less likely to use prescription opioid pain medication (7 per cent) but reported higher rates of hazardous drinking than the provincial average (19 per cent and 16 per cent respectively)
  • Students in the east reported higher rates of hazardous drinking than the provincial average (20 per cent and 16 per cent respectively)

The U.S. Health Disadvantage – Part 2: Possible Causes and Solutions

by Kirsten Hartil 

“Everyone has the right to a standard of living adequate for the health and well-being of himself and his family, including food, clothing, housing and medical care.”

At least according to Article 25 of The United Nations Universal Declaration of Human Rights, so why does the United States, one of the wealthiest countries in the world, have some of the poorest health outcomes compared to other high income countries?

My previous blog, adapted from the Institute of Medicine (IOM) report U.S. Health in International Perspective: Shorter Lives, Poorer Health, described how the U.S. compares in causes of mortality and years of life lost with other high income and OECD countries. Here, as outlined in the report, I explore some of the social determinants of health that may explain this. Social determinants of health, as opposed to biological determinants (biology and genetics), describe the…

Economic Environment During Infancy Linked With Substance Use, Delinquent Behavior in Adolescence

Us unemployment rates 1950 2005

While correlation doesn’t equate cause/effect…there just may be something here…

From the 31 December 2012 article at ScienceDaily

The larger economic environment during infancy may be associated with subsequent substance use and delinquent behavior during adolescence, according to a report published Online First by Archives of General Psychiatry, a JAMA Network publication.

“The results demonstrate a strong correlation between the unemployment rate during infancy and subsequent behavioral problems. This finding suggests that unfavorable economic conditions during infancy may create circumstances that can affect the psychological development of the infant and lead to the development of behavioral problems in adolescence,” the authors note.

According to the study results, exposure to a 1 percent deviation from mean regional unemployment rates at the age of 1 year was associated with an increase in the odds ratios of engaging in marijuana use (1.09), smoking (1.07), alcohol use (1.06), arrest (1.17), gang affiliation (1.09), and petty (1.06) and major theft (1.11). No significant associations were noted with the use of hard drugs and assaultive behavior, the results indicate.

“Although the past does not necessarily predict the future, it provides important lessons. Our findings suggest an important static risk factor that mental health professionals may want to take into account when dealing with children exposed to the current economic crisis,” the authors conclude. “We hope that the study inspires mental health professionals to look for potential causes and explore interventions that can mitigate some of these long-term consequences.”

[Reblog] Clustering of unhealthy behaviours over time Implications for policy and practice

 

From The Kings Fund (UK site)

Summary

People’s lifestyles – whether they smoke, how much they drink, what they eat, whether they take regular exercise – affect their health and mortality. It is well known that each of these lifestyle risk factors is unequally distributed in the population.

Less is known about how these behaviours co-occur or cluster in the population and about how these patterns of multiple lifestyle risk have been evolving over time. This paper considers this in the context of the English population and sets out the implications for public health policy and practice that flow from the findings.

It reviews the current evidence on multiple lifestyle risks and analyses data from the Health Survey for England on the distribution of these risks in the adult population and how this is changing over time.

You can also download the supporting methodology and data appendices (98 kb) [pdf]

Key points

  • The overall proportion of the English population that engages in three or four unhealthy behaviours has declined significantly, from around 33 per cent of the population in 2003, to 25 per cent in 2008.
  • These reductions have been seen mainly among those in higher socio-economic and educational groups: people with no qualifications were more than five times as likely as those with higher education to engage in all four poor behaviours in 2008, compared with only three times as likely in 2003.
  • The health of the overall population will improve as a result of the decline in these behaviours, but the poorest and those with least education will benefit least, leading to widening inequalities and avoidable pressure on the NHS.

Policy implications

More effective ways must be found to help people in lower socio-economic groups and those with the least education to improve their health behaviours.

This requires a more holistic approach to policy and practice, addressing lifestyles that encompass multiple rather than individual unhealthy behaviours.

In addition, behaviour change should be linked more closely to inequalities policy and be focused more directly on improving the health of the poorest.

More research and better use of the data already available is key. In particular, it would be helpful to know whether it is easier or harder to change the behaviour of those with multiple risks, whether it is more effective to tackle the risks in sequence or in tandem, what the most cost-effective approaches are and what we can learn from other areas of care.

Exposure to Sexual Content in Popular Movies Predicts Sexual Behavior in Adolescence

 

From the 17th July 2012 article at ScienceNewsDaily

Intuitively it simply makes sense: exposure to sexual content in movies at an early age probably influences adolescents’ sexual behavior. And yet, even though a great deal of research has shown that adolescents who watch more risky behaviors in popular movies, like drinking or smoking, are more likely to drink and smoke themselves, surprisingly little research has examined whether movies influence adolescents’ sexual behaviors.

Until now.

Over six years, psychological scientists examined whether or not seeing sex on the big screen translates into sex in the real world for adolescents. Their findings, which are to be published inPsychological Science, a journal of the Association for Psychological Science, revealed not only that it did but also explained some of the reasons why.

It appears from our meta-analysis that risk-glorifying media has potentially grave consequences, such as innumerable incidences of fatalities, injuries and high economic costs in a broad variety of risk-taking domains, such as substance abuse, reckless driving, gambling and risky sexual behavior,” wrote Fischer.

Among the media examined, video games that glorify risk were more likely to prompt dangerous behavior than passive exposure, such as watching films or listening to music. The authors examined research conducted between 1983 and 2009 in the United States and Europe, incorporating more than 80,000 participants. Most people were between the ages of 16 and 24, but some of the samples did include older and younger participants.

An analysis of this size helps prove that exposure to risk-glorifying media actually leads to riskier behavior, which was exemplified in several experiments, the authors said. For example, in a typical experiment, participants were first exposed to media content that either glorified risk taking — such as pictures of extreme sports or street racing video games — or did not glorify such behavior. Afterward, the researchers measured how willing the participants were to engage in certain types of risky behaviors, such as participating in extreme sports or reckless driving, measured in a computer simulation.

One study of 961 young adults found that those who watched movies showing people drinking were more likely to drink more and have alcohol-related problems later in life. Similar effects were found in other studies of smoking.

“These results support recent lines of research into the relationship between risk taking and the media,” said Fischer. “There is indeed a reliable connection between exposure to risk-glorifying media content and risk-taking behaviors, cognitions and emotions.”…

Some states in the United States have implemented laws to address school bullying. Law prohibits bullying of students based on sexual orientation and gender identity Law prohibits bullying of students based on sexual orientation only School regulation or ethical code for teachers that address bullying of students based on sexual orientation Law prohibits bullying in school but lists no specific categories of protection No statewide law that specifically prohibits bullying in schools (Photo credit: Wikipedia)

From the 6 June 2012 post at KevinMD.com

10 topics to discuss with your teen this summer

1. Marijuana. My teens ask me great questions about the physical effects of marijuana on the body. Pot seems to be the latest recreational “drug of choice”  among teen users in our area, noting that it is easier and cheaper to obtain than alcohol. With legalization arguments mounting as the Presidential election draws near, arm yourself with the facts about the risks of marijuana use  and how you can openly discuss this drug. Most importantly, be honest. Don’t lie. Don’t over-exaggerate. You want to be a trusted source worth coming back to.

2. Bullying. Stories about severe bullying are real, and sobering. Social media and cell phones have brought bullying to a new level. Most of our Kansas City area schools have bullying policies in place – encourage them to be used. There are also movements, such as Lady Gaga’s Born This Way Foundation, that are rapidly growing; showing promise that many teens are openly fighting against bullying. Encourage this in your child. Know the signs of bullying and victimization. And, act on your suspicions.

3. Recreational ADHD drug use. In my area, one Adderall XR tablet will sell for $10 during finals week. Yep, one pill. My teen…

Fewer Young People Smoking, Drinking and Using Drugs – New survey reveals encouraging trend

Heaven knows I post enough somewhat depressing health statistics items…
Here’s some good news for a change..and an example of a public health measure that seems to have worked (as always be careful when inferring cause/effect!)

From the 31 May 2012 Health Canada press release (via an RSS feed I subscribe to…Full Text Reports)

May 31, 2012
For immediate release

OTTAWA – According to the latest results of the Youth Smoking Survey, only three per cent of Canadian students in grades 6-12 said they smoked daily in 2010-2011, down from 4% in 2008-2009.

The school-based survey also found that fewer students have even tried cigarettes once; a decline among those who had ever tried little cigars; and a drop in the percent of students reporting using alcohol, cannabis and other drugs.

“After seeing smoking rates hit historic lows in Canada recently, these new statistics are encouraging,” said the Honourable Leona Aglukkaq, Minister of Health. “In particular, the drop in little cigar smoking suggests that the Cracking Down on Tobacco Marketing Aimed at Youth Act is having an impact on consumption of these products by youth.”

The Youth Smoking Survey, funded by Health Canada and conducted by the University of Waterloo’s Propel Centre for Population Health Impact, is a survey of Canadian youth in grades 6-12 that captures information related to tobacco, alcohol and drug use. Among the findings for 2010-2011:

  • Nearly three-quarters (74%) of youth in grades 6-12 said they have never tried smoking a cigarette, not even a puff, a significant increase from 67% in 2008-2009.
  • Among younger students, just 2% of those in grades 6-9 smoked daily or occasionally, the lowest smoking rate recorded by the survey since it began, in 1994.
  • Just 6% of youth in grades 6-9 had ever tried smoking little cigars, a significant decrease from 10% in the previous survey. Similarly, in grades 10-12, 26% of youth reported having ever tried smoking little cigars, also a significant decrease from 35% in 2008-2009.
  • Among students in grades 7-12, alcohol use in the past 12 months fell to 45% from 53% in 2008-2009. Although one-third (33%) of students in the past year reported binge drinking (i.e., five or more drinks on one occasion), this is a significant decrease from 39% in 2008-2009.
  • Cannabis use was reported by 21% of students in grades 7-12, compared to 27% in 2008-2009. There were also significant decreases in the use of MDMA (ecstasy), hallucinogens and salvia, and in the abuse of psychoactive pharmaceuticals.

These and other results of the survey are available on Health Canada’s website.

In recent years, the Government of Canada has taken steps to reduce smoking among Canadian youth. The Cracking Down on Tobacco Marketing Aimed at Youth Act, in force since 2010, prohibits the sale of little cigars and blunt wraps in packages of fewer than 20 units, and prohibits the sale of little cigars and other tobacco products that contain specified additives, including most flavouring agents.

Increasing Condom Use, Reducing Sexually Transmitted Infections Through Behavioral Interventions

From the 19 December 2011 Medical News Today article

Behavioral interventions aimed at reducing sexual risk behaviors, such as unprotected sex, are effective at both promoting condom use and reducing sexually transmitted infections (STIs) long after the initial intervention, according to a new report in the Journal of Acquired Immune Deficiency Syndromes. …

…Researchers found that behavioral interventions – which included HIV education, motivation and skills-based training aimed at negotiating safer sex behaviors – were successful at improving condom use and reducing incident STIs, including HIV, for up to four years. This meta-analysis is believed to be the first to examine the incidence of HIV in a wide range of at-risk populations.

Scott-Sheldon says that while it may seem intuitive that behavioral changes, such as increased condom use, will result in fewer STIs, previous studies have been unable to support that assertion.

“The association between behavioral and biological outcomes is complex, since transmission of STIs depends on a number of factors, including partner type, characteristics, and perceptions of partner safety,” she says. “Examining both outcomes, and factors associated with sexual risk behaviors, should be important in determining the efficacy of behavioral interventions.” …

Fatherhood Can Help Change a Man’s Bad Habits

From the 7 November 2011 Science Daily article

After men become fathers for the first time, they show significant decreases in crime, tobacco and alcohol use, according to a new, 19-year study.

Researchers assessed more than 200 at-risk boys annually from the age of 12 to 31, and examined how men’s crime, tobacco, alcohol, and marijuana use changed over time. While previous studies showed that marriage can change a man’s negative behavior, they had not isolated the additional effects of fatherhood.

“These decreases were in addition to the general tendency of boys to engage less in these types of behaviors as they approach and enter adulthood,” said David Kerr, assistant professor of psychology at Oregon State University and lead author of the study. “Controlling for the aging process, fatherhood was an independent factor in predicting decreases in crime, alcohol and tobacco use.”…
