Your lunch leftovers are doing no favors for urban birds’ hearts, new research shows. Fatty food scraps may be boosting the cholesterol levels of crows in U.S. cities, but whether it’s a threat to their health isn’t clear. A team from Hamilton College in Clinton, N.Y., analyzed blood cholesterol levels of 140 crow nestlings in urban and rural areas of California. Those in urban areas had higher levels of cholesterol than those in rural areas, the findings showed. The researchers also tested the impact of human food by giving nestlings in rural New York state a regular supply of cheeseburgers. They then compared the cholesterol levels of those crows with nearby nestlings that didn’t get cheeseburgers. The cheeseburger-fed nestlings’ cholesterol levels were higher, and comparable to those of the city-dwelling crows in California. But whether higher cholesterol is bad for crows is uncertain. “Despite all the bad press that it gets, cholesterol has benefits and serves a lot of essential functions,” said study author Andrea Townsend, an assistant professor of biology. “It’s an important part of our cell membranes and a component of some crucial hormones. We know that excessive cholesterol causes disease in humans, but we don’t know what level would be ‘excessive’ in a wild bird,” she explained. The study was published Aug. 26 in The Condor: Ornithological Applications journal. The researchers followed… read on >

If you or someone you love is thinking about suicide, a new review points to effective treatments that can reduce suicide risk. Some involve therapy — cognitive behavioral therapy (CBT) or dialectical behavior therapy (DBT) — while others involve medication, such as ketamine (by infusion) or lithium. “People should be aware that there are treatments, such as CBT or DBT that can be helpful for people who have thoughts of suicide,” said the study’s lead author, Kristen D’Anci. She’s senior associate director of the Center for Clinical Evidence and Guidelines at the ECRI Institute in Plymouth Meeting, Pa. D’Anci added that medications, although less well-studied, can be an option, too. The study’s findings were published Aug. 26 in the Annals of Internal Medicine. Suicide is a growing concern in the United States. The nationwide rate increased 30% between 2000 and 2016, researchers said. Why is death by suicide on the rise? One reason rates have gone up is that people are more likely to report a suicide now because it’s a known mental condition, said psychologist Jill Harkavy-Friedman, vice president of research for the American Foundation for Suicide Prevention. As for other reasons why the rate is climbing, she said, “Suicide is a complex behavior, and each person’s risk is a little different.” For some, it may be lack of access to mental health or… read on >

Swedish researchers think they have honed in on why people with attention-deficit/hyperactivity disorder (ADHD) are more likely to die prematurely. Accidental injuries, suicide and substance abuse all play a part, and psychiatric problems fuel these factors, a new study from the Karolinska Institute suggests. To arrive at that conclusion, the researchers examined data from nearly 2.7 million people born in Sweden between 1983 and 2009. Of those, 3.2% were diagnosed with ADHD. The risk of premature death was higher among adults with ADHD than children with ADHD, and people diagnosed with ADHD later in life had a higher risk of premature death than those diagnosed earlier in life, the findings showed. Accidental injuries and suicide were the leading causes of death among people with ADHD, accounting for 35.8% and 31.4%, respectively, of the 414 deaths in that group. Substance use disorders contributed substantially to the risk of death due to suicide, while the increased risk of death due to accidental injuries was evident only in those without psychiatric conditions, the study authors said in a university news release. The investigators also found that early-onset conditions such as autism were most strongly associated with premature death due to natural causes, while later-onset psychiatric conditions, such as substance use disorders, were most strongly linked with death due to unnatural causes. The study was published recently in the… read on >

Tired of that spare tire? Low-calorie diets work, but can be difficult to follow. A much simpler approach to losing weight might be to just stop eating every other day. It’s called alternate-day fasting (ADF). As the name implies, you starve yourself by fasting one day and then you feast the next, and then repeat that pattern again and again. In just the month-long trial of the ADF diet, study volunteers lost more than seven pounds. That weight loss occurred even though people on the ADF diet ate about 30% more on the days they were allowed to eat than they normally would. Even with that extra food on feast days, the study volunteers still consumed fewer calories overall because of their fasting days, the researchers explained. “This is an easy regimen — no calculation of calories — and the compliance was very high,” said the study’s senior author, Frank Madeo, a professor of molecular biology at Karl-Franzens University of Graz, in Austria. Madeo said the researchers didn’t study how the ADF diet might compare to other types of intermittent-fasting diets or to a more typical lower-calorie diet. He said that the ADF study didn’t appear to have any impact on the immune system (at least in this short-term study), but that diets that simply rely on lower caloric intake may dampen immune system function.… read on >

A staggering number of teen girls are experiencing an insidious form of relationship abuse: reproductive coercion. Researchers report that it affects 1 in 8 adolescent girls who are sexually active. Reproductive coercion is a form of abuse in which a girl or woman is pressured into pregnancy. From a male partner threatening to leave if his female partner refuses to have his baby, to poking holes in condoms before sex, the coercion can take shape in a variety of ways. “Reproductive coercion is a form of power and control exerted via influencing women’s health, sexuality and health care behavior,” said study co-author Heather McCauley, an assistant professor of social work at Michigan State University. She added that the findings highlight a broader public health issue. “Our society so often normalizes the abusive experiences girls and women have in their relationships, making it difficult for young people to recognize that what they are experiencing is not healthy,” McCauley said. Researchers described the new study — published in the August issue of the journal Obstetrics & Gynecology — as the largest look to date at how many teen girls face this pressure. Most studies of reproductive coercion have focused on young adult women. For the study, McCauley and her colleagues analyzed data collected from 550 sexually active girls between age 14 and 19 at eight school-based health… read on >

WEDNESDAY, Aug. 21, 2019 (HealthDay News) — It would be welcome news to millions if fish oil supplements were proven to help prevent diabetes. But new research delivers very disappointing data on the prospect. Previous research has hinted that fish oil supplements — which contain omega-3 fatty acids — might improve blood sugar metabolism and possibly stave off type 2 diabetes. But this latest research found no evidence that popping a daily fish oil pill could keep diabetes at bay. “This large systematic review included information from many thousands of people over long periods. Despite all this information, we don’t see protective effects, and the most trustworthy studies consistently showed little or no effect of long-chain omega-3 fats on diabetes,” said study author Lee Hooper. Additionally, she said that her group’s previous research has shown that these types of supplements also don’t protect against heart disease, stroke or early death. Hooper is a reader in research synthesis, nutrition and hydration at Norwich Medical School at the University of East Anglia, in England. Fish oil supplements can help reduce high levels of triglycerides (a type of blood fat that contributes to heart disease), Hooper noted. She said the supplements are generally considered safe to take, but added that this review found that larger doses — above four or five grams per day — of fish oil… read on >

If you’re satisfied with your life, you probably have emotional well-being. Emotional well-being can be mastered just like any other skill, according to Richard Davidson, founder of the Center for Healthy Minds at the University of Wisconsin-Madison. How? By developing four key traits, said Davidson, a neuroscientist. The first is resilience. Research at the Center for Healthy Minds found that, over time, regular mindfulness meditation can help you learn how to bounce back from adversity. Mindfulness meditation teaches you to become aware of your thoughts and emotions, center yourself and decide how you would like to proceed with the rest of your day. (Find out more at mindful.org.) Having a positive outlook is the second key trait — both finding the positive in others and being positive in the way you approach life. Another type of meditation called compassion meditation is said to bring measurable changes after two weeks of 30-minute-a-day sessions. The goal is to switch from being judgmental to being caring. Next is improving your attention level. A Harvard study found most people spend nearly half of their waking hours not paying attention to what they’re doing. Letting the mind wander typically makes people unhappy, the researchers concluded. Practice focusing on the here and now, one task or activity at a time. Finally, become more generous of spirit. This means feeling happy for… read on >

Living in the city can be hard on the senses and the spirit, but spending some time in a tree-lined park could counteract that stress, new research suggests. “Over a three-month period, we collected tweets from 4,688 Twitter users before, during and after they posted from the park,” explained study author Aaron Schwartz. He’s a Ph.D. candidate at the University of Vermont’s school of environment and natural resources and the Gund Institute for Environment. All of the 160 parks that were visited in the study were located in the city of San Francisco. About 100,000 tweets were analyzed by a hedonometer, a kind of online happiness dictionary that ranks words according to their happiness content. Tweeting “jail,” for example, would bank a score of less than 2, while a tweet of “hahaha” would render a score nearly 8. After comparing pre-park tweets to post-park tweets, the study authors concluded that parks trigger a mood bump equivalent to that seen at Christmas, the day hedonometer happiness levels hit their peak. The team didn’t track how long participants spent in parks, so they can’t say how short a visit might trigger a mood change. And some parks turned out to be better mood boosters than others. Large regional parks with lots of tree cover and vegetation conferred the biggest happiness lift, while paved urban plazas offered the… read on >

Are you having enough sex? It’s a loaded question. “Enough,” like “a lot,” means different things to different people — it could mean every night, twice a week or twice a month. Many studies have tried to pinpoint how often the average couple has sex, how that number might change at various stages in a relationship and the ideal amount for happiness. But one of the most interesting takeaways from recent research is that enough sex is whatever amount brings both sexual and marital satisfaction to both partners. It’s not the number of times detailed in a magazine article or how often your best friend and his or her partner are having it. And more isn’t always better. In fact, according to one study, couples who have a lot of sex but feel like they’re just going through the motions or that the sex is dull aren’t happier or more satisfied with the sex or their relationship. So what are the secrets of satisfied couples? They’re things that focus on the quality of sex, not the quantity. This includes being in sync with your partner when it comes to frequency and variety in lovemaking. Communication, including talking about sexual desires, is at the heart of being in sync, yet so many people still feel awkward about bringing up likes and dislikes. Having the same view… read on >

(HealthDay News) — Everyone feels lack of motivation at some point, and it doesn’t necessarily represent a mental health issue, says the Mental Health Foundation. From meeting up with friends to participating in a hobby, sometimes it can be difficult to find the motivation to get involved. To help overcome lack of motivation, the Mental Health Foundation suggests: Break tasks into manageable chunks. Write down each positive thing you go through during the day. Give yourself credit for the small things you do. Make some time for yourself. Be gentle on yourself. Be present in the moment. Ask for help when needed.
