Too much is too much: Influence of former stress levels on food craving and weight gain during the COVID-19 period.

The COVID-19 pandemic and associated social restrictions had an extensive effect on peoples' lives. Increased rates of weight gain were widely reported, as were declines in the general populations' mental health, including increases in perceived stress. This study investigated whether higher perceived levels of stress during the pandemic were associated with greater levels of weight gain, and whether poor prior levels of mental health were a factor in higher levels of both stress and weight gain during the pandemic. Underlying changes in eating behaviours and dietary consumption were also investigated. During January-February 2021, UK adults (n = 179) completed a self-report online questionnaire to measure perceived levels of stress and changes (current versus pre-COVID-19 restrictions) in weight, eating behaviours, dietary consumption, and physical activity. Participants also reported on how COVID-19 had impacted their lives and their level of mental health prior to the pandemic. Participants with higher levels of stress were significantly more likely to report weight gain and twice as likely to report increased food cravings and comfort food consumption (OR = 2.3 and 1.9-2.5, respectively). Participants reporting an increase in food cravings were 6-11 times more likely to snack and to have increased consumption of high sugar or processed foods (OR = 6.3, 11.2 and 6.3, respectively). Females reported a far greater number of COVID-19 enforced lifestyle changes and both being female and having poor mental health prior to the pandemic were significant predictors of higher stress and weight gain during the pandemic. Although COVID-19 and the pandemic restrictions were unprecedented, this study suggests that understanding and addressing the disparity of higher perceived stress in females and individuals' previous levels of mental health, as well as the key role of food cravings, is key for successfully addressing the continuing societal issue of weight gain and obesity.

Predictors of Short-Term Alcohol Drinking in Patients with Alcohol Use Disorders during the Third Wave of the COVID-19 Pandemic: Prospective Study in Three Addiction Outpatient Centers in France.

The present study investigates the extent to which the COVID-19 crisis disturbed different life domains of patients with alcohol use disorder (AUD) and assessed the associations between these disturbances and the risk of short-term alcohol drinking. All patients aged >18 years receiving outpatient care at three addiction treatment facilities from 15 April to 30 May 2021 were eligible for inclusion in the study. A trained resident assessed the extent to which the COVID-19 crisis affected their professional activity, social life, access to healthcare, and drinking problems, together with craving, drinking behavior, psychological distress, physical/mental health, and sociodemographic and clinical data. The same investigator assessed alcohol drinking 1 month after their visit. Nearly half of the patients felt that the COVID-19 crisis had a serious impact on their drinking problems, despite minor disruptions in access to healthcare. These disturbances significantly influenced short-term alcohol drinking in univariate analysis, together with psychological distress, craving, and drinking problems. Only craving predicted alcohol drinking in multivariate analyses, suggesting that psychological and drinking problems, as well as COVID-19 disturbances, increased the risk of alcohol drinking by increasing craving. Craving should be systematically investigated in patients with AUD to establish adapted social support systems during pandemics.

The impact of lofexidine on stress-related opioid craving and relapse: Design and methodology of a randomized clinical trial.

Opioid Use Disorders (OUDs) and drug overdose deaths are increasing at alarmingly high rates in the United States. Stress and dysregulation in biologic stress response systems such as the hypothalamic-pituitary-adrenal axis and noradrenergic system appear to play an important role in the pathophysiology of substance use disorders and relapse to drug use, particularly for women. Alpha-2 adrenergic agonist medications effectively decrease noradrenergic activity and have demonstrated benefit in preventing relapse to substance use and decreasing stress-reactivity and craving in cocaine- and nicotine-dependent women, compared to men. Alpha-2 adrenergic agonists may help decrease stress reactivity in individuals with OUDs and prevent relapse to drug use, but gender differences have yet to be systematically explored. We describe the rationale, study design and methodology of a randomized, double-blind, placebo-controlled clinical trial examining gender differences in stress, craving and drug use among adult men and women with OUD taking methadone or buprenorphine and randomly assigned to an alpha-2 adrenergic agonist, lofexidine, compared to placebo. In addition, we describe methods for measuring daily stress, craving and drug use in participant's natural environment as well as participant's physiological (i.e., heart rate, cortisol) and psychological (i.e., stress, craving) response to laboratory social and drug cue stressors. Lastly, we detail methods adopted to sustain research activity while following guidelines for the COVID-19 pandemic. ClinicalTrials.gov Registration Number: NCT03718065.

Tobacco Craving, Nicotine Dependence, and Quit Intentions among LGB and Non-LGB High School Students: A Quasi-Experimental Analysis.

There is evidence of higher tobacco use among lesbian or gay and bisexual (LGB) populations. However, a limited number of studies have examined whether there are differences in potential indicators of future tobacco cessation behaviors between LGB and non-LGB populations. This study examined whether sexual identity is associated with craving, nicotine dependence, and quit intentions among high school students. Data were drawn from the 2020 National Youth Tobacco Survey (n = 1642). A propensity score matching (PSM) technique was used to address covariate imbalance among sexual identity groups. Additionally, subgroup analyses were performed for both males and females. The PSM results showed higher odds of craving among students who were gay or lesbian (aOR, 1.70; 95% CI = 1.13-2.55) and bisexual (aOR, 1.89; 95% CI = 1.23-2.92) compared to heterosexual (straight) students. In the sex-based subgroup analyses, we found that gay or lesbian (aOR, 1.92; 95% CI = 1.10-3.34) and bisexual (aOR, 3.12; 95% CI, 1.46-6.66) male students had significantly higher odds of craving when compared to heterosexual/straight male adolescents. However, the association was not significant in female students. Additionally, female bisexuals had significantly lower odds for quit intention (aOR, 0.48; 95% CI = 0.29-0.81) when compared to heterosexual/straight female adolescents. Results also showed no significant differences between LGB and non-LGB students for nicotine dependence. Sexual minority adolescents, especially male adolescents, were more likely to have tobacco cravings and bisexual females had lower odds of quit intention than heterosexual peers. Prevention efforts targeting this subpopulation may be beneficial.

A Randomized Clinical Trial of Fecal Microbiota Transplant for Alcohol Use Disorder.

BACKGROUND AND AIMS: Alcohol use disorder (AUD) is associated with microbial alterations that worsen with cirrhosis. Fecal microbiota transplant (FMT) could be a promising approach. APPROACH AND RESULTS: In this phase 1, double-blind, randomized clinical trial, patients with AUD-related cirrhosis with problem drinking (AUDIT-10 > 8) were randomized 1:1 into receiving one placebo or FMT enema from a donor enriched in Lachnospiraceae and Ruminococcaceae. Six-month safety was the primary outcome. Alcohol craving questionnaire, alcohol consumption (urinary ethylglucuronide/creatinine), quality of life, cognition, serum IL-6 and lipopolysaccharide-binding protein, plasma/stool short-chain fatty acids (SCFAs), and stool microbiota were tested at baseline and day 15. A 6-month follow-up with serious adverse event (SAE) analysis was performed. Twenty patients with AUD-related cirrhosis (65 ± 6.4 years, all men, Model for End-Stage Liver Disease 8.9 ± 2.7) with similar demographics, cirrhosis, and AUD severity were included. Craving reduced significantly in 90% of FMT versus 30% in placebo at day 15 (P = 0.02) with lower urinary ethylglucuronide/creatinine (P = 0.03) and improved cognition and psychosocial quality of life. There was reduction in serum IL-6 and lipopolysaccharide-binding protein and increased butyrate/isobutyrate compared with baseline in FMT but not placebo. Microbial diversity increased with higher Ruminococcaceae and other SCFAs, producing taxa following FMT but not placebo, which were linked with SCFA levels. At 6 months, patients with any SAEs (8 vs. 2, P = 0.02), AUD-related SAEs (7 vs. 1, P = 0.02), and SAEs/patient (median [interquartile range], 1.5 [1.25] vs. 0 [0.25] in FMT, P = 0.02) were higher in placebo versus FMT. CONCLUSIONS: This phase 1 trial shows that FMT is safe and associated with short-term reduction in alcohol craving and consumption with favorable microbial changes versus placebo in patients with alcohol-associated cirrhosis with alcohol misuse. There was also a reduction in AUD-related events over 6 months in patients assigned to FMT.

Low craving control predicts increased high energy density food intake during the COVID-19 lockdown: Result replicated in an Australian sample.

This research aimed to replicate a previous UK-based finding that low craving control predicts increased intake of high energy density foods (HED) during the COVID-19 lockdown, and extend this finding to adults living in Victoria, Australia. The study also assessed whether acceptance coping moderates the relationship between craving control and increased HED food intake, and examined the associations between trait disinhibition, perceived stress and changes to HED food intake. An online survey completed by 124 adults living in Victoria, Australia (total eligible n = 147; 38.5 ± 12.9 years) during the COVID-19 lockdown showed that 49% of participants reported increased overall food intake, and 21-29% reported increased intake of HED sweet and savoury foods during the COVID-19 lockdown. Of the eating behaviour traits assessed, low craving control was the only significant predictor of increased HED sweet and savoury food intake (cognitive restraint, disinhibition and emotional eating were non-significant predictors). Perceived stress was associated with reported increases in overall savoury and sweet snack intake, but was not significantly associated with changes to specific HED food groups (sweet and savoury). In this sample, acceptance coping did not significantly moderate the relationship between craving control and increased HED food intake. Based on these replicated findings, further trials should now consider interventions targeting craving control to promote controlled food intake in individuals at-risk of weight gain during the current COVID-19 and future potential lockdowns.

Coping With Craving and Withdrawal Due to Substance Use Disorders During the COVID-19 Lockdown.

OBJECTIVE: Substance use disorder (SUD) is a chronic remitting and relapsing disorder, and abrupt discontinuation of the substance due to nonavailability in the absence of treatment precipitates withdrawals and craving. The objective of this study was to assess the craving and withdrawal coping mechanisms used by patients with SUDs as a result of disruption in availability of substances and medications due to sudden lockdown in response to coronavirus disease 2019. METHODS: A survey was administered via telephone from June 25, 2020, to July 15, 2020, to patients who had previously attended the substance use clinic of a tertiary care teaching hospital in North India from January 1, 2020, to March 21, 2020 (up to the time of lockdown). Sociodemographic and clinical details were obtained from case record files. A 16-item questionnaire was developed to collect information on coping with craving and withdrawal symptoms. A total of 215 patients were registered in the substance use clinic during this period for the treatment of SUDs, and of those, 43 could not be contacted due to various reasons such as wrong contact numbers, patient expired (not related to substance withdrawal), or not willing to talk. The mean age of the subjects was 37.05 (SD = 13.22) years, and men outnumbered women. The remaining 172 patients were contacted via telephone, and responses were gathered regarding withdrawal symptoms and coping with craving. RESULTS: More than two-thirds of the patients were still maintaining abstinence from their primary substance of abuse during lockdown. A large number of patients (n = 41, 43.2%) reported difficulty in obtaining prescribed medication for detoxification without renewal of their prescription. More than 66% of patients reported that they were able to control their craving, and many kept themselves busy with household activities. CONCLUSIONS: The majority of patients who had completed the acute phase of withdrawals were able to maintain abstinence in the absence of renewal of prescribed medication and substance of abuse due to sudden disruption in supply. The patients were able to use certain strategies to control their craving.

Susceptibility to increased high energy dense sweet and savoury food intake in response to the COVID-19 lockdown: The role of craving control and acceptance coping strategies.

Emerging evidence indicates that for some people, the COVID-19 lockdowns are a time of high risk for increased food intake. A clearer understanding of which individuals are most at risk of over-eating during the lockdown period is needed to inform interventions that promote healthy diets and prevent weight gain during lockdowns. An online survey collected during the COVID-19 lockdown (total n = 875; analysed n = 588; 33.4 ± 12.6 years; 82% UK-based; mostly white, educated, and not home schooling) investigated reported changes to the amount consumed and changes to intake of high energy dense (HED) sweet and savoury foods. The study also assessed which eating behaviour traits predicted a reported increase of HED sweet and savoury foods and tested whether coping responses moderated this relationship. Results showed that 48% of participants reported increased food intake in response to the COVID-19 lockdown. There was large individual variability in reported changes and lower craving control was the strongest predictor of increased HED sweet and savoury food intake. Low cognitive restraint also predicted greater increases in HED sweet snacks and HED savoury meal foods. Food responsiveness, enjoyment of food, emotional undereating, emotional overeating and satiety responsiveness were not significant predictors of changes to HED sweet and savoury food intake. High scores on acceptance coping responses attenuated the conditional effects of craving control on HED sweet snack intake. Consistent with previous findings, the current research suggests that low craving control is a risk factor for increased snack food intake during lockdown and may therefore represent a target for intervention.

Addictive behaviors and craving during the COVID-19 pandemic of people who have recovered from substance use disorder.

Stressors caused by the coronavirus pandemic (COVID-19) contribute to increased addictive behaviors in the general population worldwide. Little is known, however, about addictive behaviors of people who have recovered a long time ago, even years, from substance use disorder (SUD). The goal of the present research was to examine the craving for drug use and addictive behaviors (tobacco and alcohol consumption, viewing of pornography, gambling, and shopping online) of people who recovered from SUD, before and after the outbreak of the COVID-19 pandemic.Methods: During one week of isolation imposed in Israel following the outbreak of COVID-19 in April, 2020, a self-report questionnaire was distributed to a convenience sample of 113 people who had recovered from SUD, aged 22-69, 78% men.Results Fifty-one percent of participants reported craving drugs during the isolation period and engaging in addictive behaviors. Significant differences were found in tobacco and alcohol consumption, gambling, and viewing of pornography online, before and after the outbreak of the pandemic, especially in participants who reported having engaged in these addictive behaviors to some extent before the outbreak. A hierarchical linear regression showed a significant explained variance (R2=44%, p<.001), with stronger feelings of loneliness and shorter length of time free from drug use being associated with stronger craving for drugs.Conclusions: The drug addiction treatment establishment should pay close attention and strengthen communication with people who recovered from SUD. It is necessary to develop real-time anti-craving and anti-replacement addiction interventions to prevent relapses.

No evidence that prefrontal HD-tDCS influences cue-induced food craving.

This study investigated whether the application of high definition transcranial DC stimulation (HD-tDCS) to the dorsolateral prefrontal cortex reduces cue-induced food craving when combined with food-specific inhibitory control training. Using a within-subjects design, participants (N = 55) received both active and sham HD-tDCS across 2 sessions while completing a Go/No-Go task in which foods were either associated with response inhibition or response execution. Food craving was measured pre and post stimulation using a standardized questionnaire as well as desire to eat ratings for foods associated with both response inhibition and response execution in the training task. Results revealed no effect of HD-tDCS on reducing state food craving or desire to eat. Due to the COVID-19 pandemic, we were unable to achieve our maximum preplanned sample size or our minimum desired Bayesian evidence strength across all a priori hypotheses; however 6 of the 7 hypotheses converged with moderate or stronger evidence in favor of the null hypothesis over the alternative hypothesis. We discuss the importance of individual differences and provide recommendations for future studies with an emphasis on the importance of cognitive interventions.

COVID-19 Lockdown and Changes of the Dietary Pattern and Physical Activity Habits in a Cohort of Patients with Type 2 Diabetes Mellitus.

The COVID-19 lockdown clearly affected the lifestyle of the population and entailed changes in their daily habits, which involved potential health consequences, especially on patients with Type 2 Diabetes Mellitus (T2DM). We aimed to examine the impact of the lockdown caused by COVID-19 pandemic on both nutrition and exercise habits, as well as the psychological effects in patients with T2DM, compared to their usual diet and physical activity level previous to the complete home confinement. We also intended to analyse any potential variables that may have influenced these lifestyle modifications. A Food Frequency Questionnaire (FFQ), Physical Activity Questionnaire (IPAQ), Food Craving Questionnaire-State (FCQ-S) and Food Craving Questionnaire-Trait (FCQ-T) were used. Our results showed an increase in vegetable, sugary food and snack consumption. An association between levels of foods cravings and snack consumption was also found. Data also showed a high percentage of physical inactivity before the COVID-19 lockdown, which was exacerbated during the home confinement. These findings emphasise the great importance to do further research with larger study samples to analyse and explore dietary habits and to develop public health policies to promote a healthy lifestyle in terms of diet and physical activity in these patients, especially after this strict period of lockdown.
