alcohol consumption – UofL News Fri, 17 Apr 2026 17:45:05 +0000 en-US hourly 1 UofL study: Drinking alcohol could reduce chances of pregnancy /section/science-and-tech/uofl-study-drinking-alcohol-could-reduce-chances-of-pregnancy/ Wed, 09 Jun 2021 13:43:41 +0000 http://www.uoflnews.com/?p=53693 As few as three alcoholic drink a weeks could make it more difficult for a woman to become pregnant, particularly if the drinking occurs in the second half of her menstrual cycle. The study, published this week in , investigated alcohol intake and the probability of conceiving it is the first study to evaluate the association during specific phases of the menstrual cycle.

University of Louisville School of Public Health and Information Sciences researcher Kira Taylor and her team analyzed data from more than 400 women for up to 19 months. The women completed daily diaries reporting how much alcohol they drank and what type.

Heavy drinking was defined as more than six alcoholic drinks a week, moderate drinking was three to six drinks a week, and binge drinking was defined as four or more drinks on a single day. A drink was defined as a third of a liter of beer, a medium glass of wine or just under a double shot of spirits. The researchers collected information on factors that could affect the results, such as age, medical history, smoking, obesity, intercourse frequency, use of birth control methods and intention to become pregnant.

“We found that heavy drinking during any phase of the menstrual cycle was significantly associated with a reduced probability of conception compared to non-drinkers,” Taylor said. “This is important because some women who are trying to conceive might believe it is ‘safe’ to drink during certain parts of the menstrual cycle.”

The research also found during the luteal phase, or the last two weeks of the menstrual cycle before bleeding starts and when the process of implantation occurs, not only heavy drinking but also moderate drinking was significantly associated with a reduced probability of conception. At the time of ovulation, usually around day 14 of the cycle, consuming a lot of alcohol – either heavy or binge drinking – was significantly associated with reduced chances of conception.

“If we assume that a typical, healthy, non-drinking woman in the general population who is trying to conceive has approximately a 25% chance of conceiving during one menstrual cycle, then out of 100 women approximately 25 non-drinkers would conceive in a particular cycle, about 20 moderate drinkers would conceive and only about 11 heavy drinkers would conceive,” Taylor said. “But the effect of moderate drinking during the luteal phase is more pronounced and only about 16 moderate drinkers would conceive.

“Our study only included a few hundred women and, while we believe the results strongly suggest that heavy and even moderate alcohol intake affects the ability to conceive, the exact percentages and numbers should be viewed as rough estimates,” she said.

Each extra day of binge drinking was associated with an approximate 19% reduction in the odds of conceiving during the luteal phase and a 41% reduction during the ovulatory phase. The researchers found no difference in their results between different types of drinks. The influence of drinking by male partners was not assessed.

While the study does not show that drinking alcohol causes the reduction in the chances of becoming pregnant, it does point to an association. Possible biological mechanisms to explain the association could be that alcohol intake affects the processes involved in ovulation so that no egg is released during the ovulatory part of the cycle, and alcohol could affect the ability of a fertilized egg to implant in the womb.

“The results in this study should not be construed to mean that drinking alcohol prevents pregnancy. In other words, alcohol is not birth control. Even if a woman drinks alcohol heavily, if she has unprotected intercourse, she can become pregnant,” Taylor said.

UofL researchers discover relationship between Uber, binge drinking /post/uofltoday/uofl-researchers-discover-relationship-between-uber-binge-drinking/ Tue, 17 Dec 2019 19:49:18 +0000 http://www.uoflnews.com/?p=49150 Think about the different times you’ve been with friends and someone mentions needing to utilize a ride-sharing service like Uber. While such services are often viewed as a responsible decision, researchers from the University of Louisville and Georgia State University have discovered that the increasing availability of .

Economists Jacob Burgdorf and Conor Lennon from UofL and Keith Teltser at Georgia State University looked at data from 2009, when Uber was introduced, through 2016, and included UberX’s arrival in 2012.Their paper signals total alcohol consumption and binge drinking both have risen in the period measured.

“Uber is naturally interesting because it’s this new thing; Jacob has research on beer distributors – he’s a beer industry guy – and I have co-authored a paper with Keith on bourbon and secondary markets for bourbon,” Lennon said, “so we have research on the alcohol industry, so naturally we were curious how does alcohol affect this (ride-sharing) industry.”

According to the research, it was determined that Uber has a larger effect on drinking in areas where public transportation is limited, noting a 17.5-to-21.8% increase in instances of binge drinking in those locales.

The findings also showed that Uber’s arrival coincides with an increase in average drinks, including a 4.9% rise in drinks on a single occasion and a 9% increase in incidences of heavy drinking.

“We were kind of surprised that nobody had focused exactly on this thing; everybody was focused on this secondary thing, which is drunk driving, which is after the fact,” Lennon said. “You have to make sure they’re not drinking more and drinking to excess and causing harm in other ways.

“Nobody had measured the first step.”

Burgdorf, Lennon, and Teltser also used their findings to investigate Uber’s impact on full-service restaurants, on the premise the ride-sharing app would have a positive effect on earnings at establishments serving alcohol. However, they found no significant impact on revenue, further suggesting that Uber is associated with increased consumption at “drinking places” and not full-service restaurants.

“If you go to Uber’s website, it says they’re strongly against drunk driving, and they have these free rides for people who are drunk, but they proudly announce that their busiest times are right around bar-closing time across the country,” Lennon said.

“… If Uber is announcing that, that’s almost telling you what Uber’s role is. It’s smacking you right in the face; the shocking thing is nobody wrote this paper before.”

UofL’s BRICC Coalition works to increase students’ resiliency, reduce high risk behaviors /post/uofltoday/uofls-bricc-coalition-works-to-increase-students-resiliency-reduce-high-risk-behaviors/ /post/uofltoday/uofls-bricc-coalition-works-to-increase-students-resiliency-reduce-high-risk-behaviors/#respond Mon, 20 Feb 2017 19:10:38 +0000 http://uoflnews.com/?p=35402  

Did you know that alcohol misuse is the fifth leading risk factor for premature death and disability globally and among people between the ages of 15 and 49, it is the first? For those 20 to 39 years old, approximately 25 percent of the total deaths are alcohol attributable.

A group at UofL is working to ensure our students don’t fall victim to these statistics. The Building Resiliency in Campus Community (BRICC) Coalition, a Campus Health Services partnership, was created in 2007 in an effort to advance policies, programs and resources that increase resiliency and reduce high risk drinking on campus and in the community.

In 2010, Heather Parrino came on board as program manager. BRICC has since secured major gifts from Beam Suntory and Brown-Forman to support staff, programming, and infrastructure. They have developed additional resources, including the Voice of Reason manual and other initiatives that Parrino says have yielded tremendous success.

“We’ve been very successful because we have so many committed volunteers (about 200), we work with community and campus partners and we have external funding. I think we’re also serving as leaders in this area because we meet students where they are,” Parrino said.

That means, for example, hosting meetings in the basement of a fraternity house or sharing relevant information on residence hall bulletin boards.

Parrino specifically measures success through three metrics:

  1. UofL’s AlcoholEdu (alcohol prevention) and Haven (sexual violence prevention) programs, funded by the president, provost, and Campus Health Services. (AlcoholEdu is mandated for every first time freshmen and transfer student under 21 and Haven is required for every student. AlcoholEdu educates students about the impact of alcohol and how to prevent high-risk situations where alcohol is present. Haven addresses critical issues of sexual assault, relationship violence, stalking, and sexual harassment.
  1. A state law () passed in 2013 to provide immunity from prosecution for students who choose to call for help in an emergency.

“We support students that choose to drink and students that choose not to drink. We want to make sure all of our students stay safe,” she said.

  1. UofL developed the Voice of Reason manual about three years ago so that students could have tangible takeaways from their prevention training programs. The manual was created after an in-depth needs assessment, in partnership with Pacific Institute for Research and Evaluation, was completed in 2010, which included a focus groups of students and staff throughout campus.

“We rode in police cars, we came to campus at night, we went into apartment complexes. We would talk to anyone who would talk to us. In our needs assessment, we realized there is a lot of misinformation out there about alcohol use and that much of the communication is ineffective and disingenuous,” Parrino said. “This was our base for the Voice of Reason manual.”

Much of BRICC’s current strategic plan also came out of the needs assessment. The main objective is to “build resilience.”

“Alcohol isn’t the number one issue, resilience is,” Parrino said. “There are two main reasons people drink – to celebrate and to deal with stress. If we can teach students how to celebrate differently – going to dinner with their friends, going on a hike, etc. – then we can teach them life skills development to avoid major issues. We can teach them resilience. At the end of the day, the stress and the reason for celebrating are still there.”

BRICC has been using the Voice of Reason manual for three years. It has been so effective, Parrino said, the University of Kentucky is piloting it this year.

BRICC also features a number of other programs, including:

  • TIPs Training. TIPs stands for Training for Intervention Procedures. TIPs University certification is beneficial for students who are in charge of planning events, serving as RAs, risk management chairs and in other leadership positions. TIPs University “recognizes that students are in the best position to address drinking behaviors among their peers,” or, as Parrino explains, “meeting students where they are.”
In BRICC’s fall semester training, 68 RAs were certified prior to campus move-in day.

BRICC offers monthly TIPs University certifications to students and campus/community partners that serve students. The classes last four hours. In BRICC’s fall semester training, 68 RAs were certified prior to campus move-in day.

“My favorite part as a TIPs trainer is watching people arrive thinking they are going to listen to a boring lecture about alcohol information. Our participants become very engaged as they realize they are the experts and we are going to work together to facilitate conversations to address issues that are specific to them and their friends,” Parrino said.

  • BRICC Wall. The engages students with community members, businesses and city officials to “make changes in their communities and remove roadblocks to their academic success.” The exhibit challenges assumptions and encourages healthy decisions. It is made up of messages from students sharing their own stories about alcohol and substance abuse. The messages are written on “bricks” displayed as part of the exhibit.
  • Greeks Advocating Matuer Management of Alcohol (GAMMA). BRICC provides funding, resources, and a staff advisor for Greeks Advocating Mature Management of Alcohol, a UofL RSO. In the fall, GAMMA members lead the Voice of Reason initiative, a strategy to help both drinkers and nondrinkers make safer decisions in social settings. VOR includes five one-hour sessions that cover basic alcohol knowledge, awareness of risks, effective messaging and implementing strategies.
  • This semester, BRICC will also launch a new RSO called “Advocates for Recovery.” The first meeting is March 9. The organization will offer broad-based support to students in recovery, and will also include friends and allies of students in recovery. Programming will focus on increasing resilience, academic achievement, health and overall wellbeing.

Though the organization is still in the planning phase, Parrino said more than 150 students have expressed interest.

“As with everything we’ve done, we need to start from the ground and we need to find allies,” Parrino said. “I look at what we’re doing as more macro than programming. Our students need more than programming. We are constantly looking at how we can take care of them.”
