NEWS Wallowa.com Wednesday, July 31, 2019 B3 Smartphones cause problems for college students Craig Berkley Cambridge University A survey of more than 3,400 university students in the USA has found that one in fi ve respondents reported problematic smartphone use. Female students were more likely be affected and prob- lematic smartphone use was associated with lower grade averages, mental health problems and higher num- bers of sexual partners. Smartphones offer the potential of instant, round- the-clock access for making phone calls, playing games, gambling, chatting with friends, using messenger systems, accessing web ser- vices (e.g. websites, social networks and pornography), and searching for informa- tion. The number of users is rapidly increasing, with some estimates suggesting that there are now more than 2.7 billion users worldwide. While most people using smartphones fi nd them a helpful and positive part of life, a minority of users develop excessive smart- phone use, meaning that smartphone use has signifi - cant negative effects on how people function in life. Pre- vious research has linked excessive smartphone use to mental health issues such as anxiety, depression, post-traumatic stress disor- der (PTSD), attention defi - cit hyperactivity disorder (ADHD) and problems with self-esteem. A collaborative team of researchers from the Univer- sity of Chicago, University of Cambridge, and the Uni- versity of Minnesota, devel- oped the Health and Addic- tive Behaviours Survey to assess mental health and well-being in a large sample of university students. They used the survey to investi- gate the impact of smart- phone use on university students. Just over a third (3,425) of students invited to take the test responded. The results are published today A Cambridge University study found that excessive smartphone use can create problems for college student.s in the Journal of Behavioral Addictions. The self-report survey consisted of 156 questions. Based on their responses, the students were given a score ranging from 10 to 60, with a score of 32 and above being defi ned as problem- atic smartphone use. This defi nition was based on a threshold recommended pre- viously in clinical valida- tion studies using the scale. Typical characteristics of problematic use include: excessive use; trouble con- centrating in class or at work due to smartphone use; feel- ing fretful or impatient with- out their smartphone; miss- ing work due to smartphone use; and experiencing phys- ical consequences of exces- sive use, such as light-head- edness or blurred vision. The researchers found that one in fi ve (20%) of respondents reported prob- lematic smartphone use. Problematic smartphone use was greater among female rather than male stu- dents – 64% of problem users were female. Impor- tantly, the researchers found a link between problematic smartphone use and lower grade point averages (aca- demic achievement). “Although the effect of problematic smartphone use on grade point averages was relatively small, it’s worth noting that even a small neg- ative impact could have a profound effect on an indi- vidual’s academic achieve- ment and then on their employment opportunities in later life,” said Professor Jon Grant from the Department of Psychiatry & Behavioral Neuroscience at the Univer- sity of Chicago. While students reporting problematic smartphone use tended be less sexually active than their peers (70.9% com- pared to 74%), the propor- tion of students reporting two or more sexual partners in the past 12 months was signifi cantly higher among problem users: 37.4% of sexually-active problematic smartphone users compared with 27.2% sexually-active students who reported no problem use. The proportion with six or more sexual part- ners was more than double among sexually-active prob- lematic smartphone users (6.8% compared to 3.0%). “Smartphones can help connect people and help people feel less isolated, and our fi ndings suggest that they may act as an avenue for sexual contact, whether through sustained partner- ships or more casual sex,” added Dr Sam Chamberlain, Wellcome Trust Clinical Fel- low and Honorary Consul- tant Psychiatrist from the Department of Psychiatry at the University of Cambridge and the Cambridge & Peter- “It’s easy to think of prob- lematic smartphone use as an addiction, but if it was that simple, we would expect it to be associated with a wide range of substance misuse problems, especially in such a large sample, but this does not seem to be the case,” added Dr Sam Chamberlain. “One possible explana- tion for these results is that people develop excessive smartphone use because of other mental health diffi - culties. For example, peo- ple who are socially iso- lated, those who experience depression or anxiety, or those who have attention problems (as in ADHD) may be more prone to excessive smartphone use, as well as to using alcohol. Smartphone use likely develops earlier in life – on average – than alco- hol use problems and so it is unlikely that alcohol use itself leads to smartphone use.” borough NHS Foundation Trust. The researchers found that alcohol misuse was sig- nifi cantly higher in those with problematic smart- phone use compared to the control group. To assess this, the team used a scale known as the Alcohol Use Disor- ders Identifi cation Test: a score of eight or above indi- cates harmful alcohol use. 33.3% of problematic smart- phone users scored eight or above compared to 22.5% of other smartphone users. The researchers found no sig- nifi cant link with any other form of substance abuse or addiction. In terms of other men- tal health problems, the researchers found that prob- lematic smartphone use was signifi cantly associated with lower self-esteem, ADHD, depression, anxiety, and PTSD, mirroring similar fi ndings elsewhere. New research on historic megadroughts may help predict future climatic events Nicole deRoberts Columbia University About a dozen mega- droughts struck the Ameri- can Southwest during the 9th through the 15th centuries, but then they mysteriously ceased around the year 1600. What caused this clustering of megadroughts — that is, severe droughts that last for decades — and why do they happen at all? If scientists can under- stand why megadroughts happened in the past, it can help us better predict whether, how, and where they might happen in the future. A study published today in Science Advances provides the fi rst comprehensive the- ory for why there were megadroughts in the Ameri- can Southwest. The authors found that ocean temperature conditions plus high radia- tive forcing — when Earth absorbs more sunlight than it radiates back into space — play important roles in trig- gering megadroughts. The study suggests an increasing risk of future megadroughts in the American Southwest due to climate change. Previously, scientists have studied the individ- ual factors that contribute to megadroughts. In the new study, a team of scientists at Columbia University’s Lam- ont-Doherty Earth Obser- vatory has looked at how multiple factors from the global climate system work together, and projected that warming climate may bring a new round of megadroughts. By reconstructing aquatic climate data and sea-sur- face temperatures from the last 2,000 years, the team found three key factors that led to megadroughts in the American Southwest: radia- tive forcing, severe and fre- quent La Niña events — cool tropical Pacifi c sea surface temperatures that cause changes to global weather events — and warm condi- tions in the Atlantic. High radiative forcing appears to have dried out the Ameri- can Southwest, likely due to an increase in solar activ- ity (which would send more radiation toward us) and a decrease in volcanic activity (which would admit more of it) at the time. The resulting increase in heat would lead to greater evaporation. At the same time, warmer than usual Atlantic sea-surface temperatures combined with very strong and frequent La Niñas decreased precipita- tion in the already dried-out area. Of these three factors, La Niña conditions were esti- mated to be more than twice as important in causing the megadroughts. While the Lamont scien- tists say they were able to pinpoint the causes of mega- droughts in a more com- plete way than has been done before, they say such events will remain diffi cult for sci- entists to predict. There are predictions about future trends in temperatures, arid- ity, and sea surface tempera- tures, but future El Niño and La Niña activity remains dif- fi cult to simulate. Neverthe- less, the researchers conclude that human-driven climate Introducing Orthopedic Surgeon Dr. Adam Heisinger change is stacking the deck towards more megadroughts in the future. “Because you increase the baseline aridity, in the future when you have a big La Niña, or several of them in a row, it could lead to mega- droughts in the American West,” explained lead author Nathan Steiger, a Lam- ont-Doherty Earth Observa- tory hydroclimatologist. During the time of the medieval megadroughts, increased radiative forc- ing was caused by natu- ral climate variability. But today we are experiencing increased dryness in many locations around the globe due to human-made forces. Climate change is setting the stage for an increased possi- bility of megadroughts in the future through greater aridity, say the researchers.
