The Covid-19 pandemic has altered health behaviours of many individuals resulting in weight gain. This cross-sectional study of 1779 individuals aimed to determine the long-term impact of Covid-19 on health behaviours and weight gain over 5 months. The results showed that most participants (40%) body weight increased alongside increased processed food intake and snacking. 33% of the individuals who gained weight continued to gain weight and 28% maintained their higher weight after lockdown measures were lifted. Take-away meals, processed food intake and stress levels remained high post-lockdown in those who gained weight. It was concluded that lockdown measures may have impacted daily life resulting in weight gain which may perpetuate long-term. This study could be used by healthcare professionals to understand that lockdown measures may have altered eating behaviours resulting in weight gain and that these may need to be uncovered to aid long-term weight loss.
Abstract
Cross-sectional analyses have shown increased obesogenic behaviors and a potential for weight gain during COVID-19 related peak-lockdown (March-May 2020), but longitudinal data are lacking. This study assessed longitudinal changes in body weight and lifestyle behaviors in the US adults during the pandemic. METHODS We used Qualtrics survey to collect self-reported data on body weight, dietary, physical activity, and psychological variables (n = 727) during the peak-lockdown (April/May) and at post-lockdown (September/October). Peak-lockdown weight data were categorized based on the magnitude of weight gained, maintained, or lost, and behavioral differences were examined between categories at two time points. RESULTS Body weight increased (+0.62 kg; p < 0.05) at the post-lockdown period. The body mass index also increased (26.38 ± 5.98 kg/m2 vs. 26.12 ± 5.81 kg/m2; p < 0.01) at the post-lockdown period vs. peak-lockdown period. Close to 40% of participants reported gaining either 1-4 lbs or >5 lbs of body weight during the peak-lockdown, while 18.2% lost weight. Weight-gainers engaged in riskier dietary behaviors such as frequent ultra-processed food intake (p < 0.01) and snacking (p < 0.001), were less active, and reported high stress and less craving control during peak-lockdown. Of those gaining >5 lbs, 33% continued to gain weight after the lockdown eased, while 28% maintain higher body weight. In weight-gainers, takeout meal frequency increased, and high ultra-processed food intake and stress, and low craving control continued to persist after the lockdown eased. CONCLUSION We show that the COVID-19 lockdown periods disrupted weight management among many Americans and that associated health effects are likely to persist.

Vaginal microbiotas are clustered into five different possible categories, according to their bacterial dominance. The aim of this study was to evaluate a possible correlation between the vaginal microbiota and the 90-day persistence of Human Papilloma Virus (HPV) infection - both high-risk (HR) and low-risk (LR) strains - in the cervical-vaginal area. The study is an observational, open, pilot study. Participants included a group of 35 women with HPV cervical infection, with normal or abnormal cervical cytology, and recurrent vaginal infections. Results show that after 90 days of treatment with L. crispatus M247, 97% of women had a vaginal microbiota that was Lactobacillus-dominated. Furthermore, after 90 days, 71% of women were HPV-negative, with respect to both HR and LR strains, and 29% were still infected by HR-HPV strains. Authors conclude that their findings are preliminary and uncontrolled, thus further investigation with a higher number of women with HPV infection would help to verify the long-term effect of L. crispatus M247.
Abstract
BACKGROUND Vaginal microbiotas can be clustered into five different possible categories (CST I to V), according to their bacterial dominance. In CST I, the dominance of Lactobacillus crispatus seems to correlate with better vaginal health and with a lower incidence of sine causa infertility, preterm delivery, bacterial vaginosis, and viral (including human papillomavirus; HPV) infection. According to the same method of classifying the vaginal microbiome, CST IV (non-Lactobacillus-dominated) demonstrates a higher incidence of disorders. METHODS In an open, non-controlled study, we enrolled 35 HPV-positive women who mostly (N.=24) demonstrated CST IV status, with the other individuals categorized as having either CST III (N.=10) or CST II (N.=1) microbiotas. RESULTS After 90 days of oral treatment with a probiotic (L. crispatus M247) we observed a reduction of approximately 70% in HPV positivity and a significant change in CST status with 94% of women now classified as CST I. CONCLUSIONS Despite the limitations of our study, it is the first demonstration that it is possible to intervene orally with an L. crispatus probiotic to bring about a change in CST status and, in parallel, increased HPV clearance.

Polycystic ovary syndrome (PCOS) is one of the most common reproductive endocrine and metabolic disorders that affects up to 10% women of childbearing age. The aim of this study was to explore the effects of time-restricted feeding (TRF) on menstruation, gonadal and metabolic parameters in women with anovulatory PCOS and propose a basis for its inclusion in the treatment of PCOS. This study is a 6-week trial with 2 consecutive periods: (1) 1-week baseline weight stabilization period; and (2) 5-week TRF period. Fifteen subjects were included in the study whose age varied between 18 and 31 years. Results show that five weeks of TRF improved menstruation, gonadal profiles, body weight, body mass index, body composition profiles, hyperinsulinemia and insulin resistance profiles, decreasing chronic inflammation markers and increasing insulin growth factor –1 [hormone]. Authors conclude that TRF may be suitable for PCOS women with appropriate counselling and patient management.
Abstract
BACKGROUND Time-restricted feeding (TRF) is a form of intermittent fasting, which is beneficial for weight loss and cardiometabolic health. Polycystic ovary syndrome (PCOS) is one of the most common reproductive endocrine and metabolic diseases affecting women of childbearing age. It is associated with an increased prevalence of metabolic syndrome, cardiovascular diseases and type 2 diabetes. The effects of TRF on PCOS patients remains undefined, here we investigated the impact of TRF on women with anovulatory PCOS. METHODS Eighteen PCOS women aged between 18 and 31 with anovulation participated in a 6-week trial which were divided into two consecutive periods: (1) 1-week baseline weight stabilization period and (2) 5-week TRF period. Fifteen participants completed the study. Changes in body weight, body mass index (BMI), Waist-to-Hip Ratio, skeletal muscle mass, body fat mass (BFM), body fat percentage (BF%), visceral fat area (VFA), luteinizing hormone (LH), follicle-stimulating hormone (FSH), LH/FSH, total testosterone (TT), sex hormone-binding globulin (SHBG), free androgen index (FAI), fasting glucose, fasting insulin (FINS), homeostasis model assessment-insulin resistance (HOMA-IR), area under the curve (AUC) for insulin (AUCIns), area under the curve (AUC) for glucose (AUCGlu), AUCIns/AUCGlu Ratio, lipids, uric acid, alanine aminotransferase (ALT), aspartate aminotransferase, high-sensitivity C-reactive protein (hsCRP), insulin-like growth factor (IGF-1), menstrual cycle and eating behaviors were evaluated. RESULTS Significant changes in body weight, BMI, BFM, BF%, VFA, TT, SHBG, FAI, FINS, HOMA-IR, AUCIns, AUCIns/AUCGlu Ratio, ALT, hsCRP and IGF-1 were found after the TRF period. An improvement in menstrual cycle irregularity was detected in 73.3% (11/15) patients. CONCLUSION The diet of TRF may be beneficial to anovulatory PCOS on weight loss especially reducing body fat, improving menstruation, hyperandrogenemia, insulin resistance and chronic inflammation.

Plain language summary
During the menopause, hormonal changes can trigger uncomfortable symptoms such as hot flashes, night sweats, sleep disturbances, and vaginal dryness. Hormone replacement therapy does reduce some of the symptoms, however there has been an increased interest in alternative therapies such as phytoestrogens to relieve these symptoms. Phytoestrogens are compounds with oestrogen-like properties naturally found in plants. Beer is the main food source of the strongest phytoestrogen identified to date. The aim of this six-month parallel, controlled clinical intervention trial was to evaluate if a moderate daily intake of beer, with or without alcohol, could reduce menopausal symptoms in women. Female sex hormone profile and cardiovascular risk factors (CVRF) were also monitored. 34 postmenopausal women took part. One group included alcoholic beer (AB), and a second group added non-alcoholic beer (NAB) for 6 months. The control group took no alcohol in this time. After a 6-month follow-up both groups (AB and NAB) significantly reduced the severity of the menopause-related symptoms. These results must be considered as preliminary and will require confirmation with larger sample sizes.
Abstract
The menopausal transition can be a challenging period for women's health and a trigger of uncomfortable symptoms. Beer is the main food source of isoxanthohumol, a precursor of 8-prenylnaringenin, the strongest phytoestrogen identified to date. As phytoestrogens are reported to reduce perimenopausal symptoms, we evaluated if a daily moderate consumption of beer with (AB) and without alcohol (NAB) could improve menopausal symptoms and modify cardiovascular risk factors. A total of 37 postmenopausal women were enrolled in a parallel controlled intervention trial and assigned to three study groups: 16 were administered AB (330 mL/day), 7 NAB (660 mL/day), and 14 were in the control group. After a 6-month follow-up of the 34 participants who finished the trial, both interventions (AB and NAB) significantly reduced the severity of the menopause-related symptoms (p-value AB vs. Control: 0.009; p-value NAB vs. Control: 0.033). Moreover, AB had a beneficial net effect on psychological menopausal discomforts compared to the control group. As the sex hormone profile did not differ significantly between the study groups, the effects of both types of beers (AB and NAB) are attributed to the non-alcoholic fraction of beer. Furthermore, moderate NAB consumption improved the lipid profile and decreased blood pressure in postmenopausal women.

Plain language summary
Caffeine is a common ingredient in tea, coffee, chocolate, soft drinks and multi-ingredient pre-workout supplements. It is believed to elicit an ergogenic effect that enhances athletic performance. However, only very few studies have examined the effect of caffeine on women who take contraceptive pills. The aim of this double-blind, randomised, counterbalanced, crossover trial was to investigate the ergogenic effect of pre-exercise caffeine supplementation on strength performance and muscular endurance in strength-trained females taking contraceptives. Fourteen women were randomised to consume doses of 3 and 6 mg·kg−1 body mass of caffeine supplement or placebo thirty minutes prior to the exercise. Caffeine supplementation at 3 and 6 mg·kg−1 body mass significantly improved muscular endurance and total strength. No significant difference was observed between the higher and lower doses of caffeine in improving performance, indicating that the lower dose can potentially provide the same benefit without the adverse effect of the higher dose. The low dose had a similar caffeine content to that of a large coffee latte from a coffee shop, suggesting beneficial effects could be achieved through coffee/latte consumption. Caution should be applied when extrapolating the findings for eumenorrheic females with different training statuses. Healthcare practitioners can, however, use the results of this study to understand the potential benefits of caffeine for strength-trained women using hormone contraception.
Abstract
Caffeine supplementation has shown to be an effective ergogenic aid enhancing athletic performance, although limited research within female populations exists. Therefore, the aim of the investigation was to assess the effect of pre-exercise caffeine supplementation on strength performance and muscular endurance in strength-trained females. In a double-blind, randomised, counterbalanced design, fourteen strength-trained females using hormonal contraception consumed either 3 or 6 mg·kg-1 BM of caffeine or placebo (PLA). Following supplementation, participants performed a one-repetition maximum (1RM) leg press and repetitions to failure (RF) at 60% of their 1RM. During the RF test, rating of perceived exertion (RPE) was recorded every five repetitions and total volume (TV) lifted was calculated. Repeated measures ANOVA revealed that RF (p = 0.010) and TV (p = 0.012) attained significance, with pairwise comparisons indicating a significant difference between 3 mg·kg-1 BM and placebo for RF (p = 0.014), with an effect size of 0.56, and for 6 mg·kg-1 BM (p = 0.036) compared to the placebo, with an effect size of 0.65. No further significance was observed for 1RM or for RPE, and no difference was observed between caffeine trials. Although no impact on lower body muscular strength was observed, doses of 3 and 6 mg·kg-1 BM of caffeine improved lower body muscular endurance in resistance-trained females, which may have a practical application for enhancing resistance training stimuli and improving competitive performance.

Depression and obesity are significant global health concerns. Depression can significantly impact physical health and reduced immune function. The aim of this study was to examine the potential benefits of a novel group psychological intervention program. The study is a preliminary quasi-experimental (single-arm) before-after pilot trial of a newly developed group-based psychological intervention program for people with depression and comorbid obesity. The program consisted of 10 two-hour group sessions held weekly. A total of 24 participants were recruited to the program across two pilot groups. Results indicate that there was a significant reduction in participants’ depression and anxiety scores by program-end. Some evidence also shows improvements in weight-related negative cognitions. Authors conclude that the group therapy program therefore has considerable potential to be effective in helping people enjoy better mental health and improve health outcomes.
Abstract
BACKGROUND Depression and obesity are significant global health concerns that commonly occur together. An integrated group cognitive behavioural therapy program was therefore developed to simultaneously address comorbid depression and obesity. METHODS Twenty-four participants (63% women, mean age 46 years) who screened positively for depression with a body mass index ≥25 were recruited from a self-referred general population sample. The group therapy program (10 two-hour weekly sessions) was examined in a single-arm, before-after pilot trial, conducted in a behavioural health clinic in Adelaide, Australia. Primary outcomes included survey and assessment-based analyses of depression, anxiety, body image, self-esteem, and weight (kg), assessed at four time-points: baseline, post-intervention, three-months and 12-months post program. Eighteen participants (75%) completed the program and all assessments. RESULTS Significant improvements in depression, anxiety, self-esteem and body shape concern scores, several quality of life domains, eating behaviours and total physical activity (among others) - but not weight - were observed over the course of the trial. CONCLUSIONS Results from this pilot trial suggest that combining interventions for depression and obesity may be useful. Further development of the program, particularly regarding the potential for physical health benefits, and a randomised controlled trial, are warranted. TRIAL REGISTRATION Trial registration: ANZCTR, ACTRN12617001079336, 13 July 2017. Retrospectively registered after date of the first consent (6 July 2017), but before the date of the first intervention session (20 July 2017).

Plain language summary
Non-alcoholic fatty liver disease (NAFLD) is characterised by the accumulation of fat in the liver of people who drink very little or no alcohol. NAFLD is a common problem in children with obesity and diet is a contributory factor. Recent research has suggested that the Western diet and its high omega-6 and low omega-3 fat intakes may lead to the development of NAFLD. This quasi-experimental study of twenty children with obesity and NAFLD aimed to determine whether 12 weeks of low omega-6: omega-3 ratio diet affected liver fat content. The results showed that the diet did not affect weight loss but still significantly decreased liver fat content, with one third of the participants returning their liver fat content to normal. In lieu of weight loss, improvements were also observed in markers for liver function, diabetes and blood cholesterol. Interestingly those who carry a certain gene increasing their risk of developing NAFLD, showed greater improvements in liver fat percentage and liver function. It was concluded that in the absence of weight loss, a diet high in omega-3 and low in omega-6 improves fatty liver disease, risk factors for heart disease and has the potential to revert liver fat content to normal levels. This study could be used by healthcare professionals to recommend a low omega-6:omega-3 diet in children with obesity and NAFLD.
Abstract
BACKGROUND Recent literature suggests that the Western diet's imbalance between high ω-6 (n-6) and low ω-3 (n-3) PUFA intake contributes to fatty liver disease in obese youth. OBJECTIVES We tested whether 12 wk of a low n-6:n-3 PUFA ratio (4:1) normocaloric diet mitigates fatty liver and whether the patatin-like containing domain phospholipase 3 (PNPLA3) rs738409 variant affects the response. METHODS In a single-arm unblinded study, obese youth 9-19 y of age with nonalcoholic fatty liver disease were treated with a normocaloric low n-6:n-3 PUFA ratio diet for 12 wk. The primary outcome was change in hepatic fat fraction (HFF%), measured by abdominal MRI. Metabolic parameters included alanine aminotransferase (ALT), lipids, measures of insulin sensitivity, and plasma oxidized linoleic acid metabolites (OXLAMs). Outcomes were also analyzed by PNPLA3 rs738409 genotype. Wilcoxon's signed rank test, the Mann-Whitney U test, and covariance pattern modeling were used. RESULTS Twenty obese adolescents (median age: 13.3 y; IQR: 10.5-16.4 y) were enrolled and 17 completed the study. After 12 wk of dietary intervention, HFF% decreased by 25.8% (P = 0.009) despite stable weight. We observed a 34.4% reduction in ALT (P = 0.001), 21.9% reduction in triglycerides (P = 0.046), 3.28% reduction in LDL cholesterol (P = 0.071), and a 26.3% improvement in whole body insulin sensitivity (P = 0.032). The OXLAMs 9-hydroxy-octadecandienoic acid (9-HODE) (P = 0.011), 13-HODE (P = 0.007), and 9-oxo-octadecadienoic acid (9-oxoODE) (P = 0.024) decreased after 12 wk. HFF% declined in both the not-at-risk (CC/CG) and at-risk (GG) PNPLA3 rs738409 genotype groups, with significant (P = 0.016) HFF% reduction in the GG group. Changes in 9-HODE (P = 0.023), 9-oxoODE (P = 0.009), and 13-oxoODE (P = 0.003) differed between the 2 genotype groups over time. CONCLUSIONS These data suggest that, independently of weight loss, a low n-6:n-3 PUFA diet ameliorates the metabolic phenotype of adolescents with fatty liver disease and that response to this diet is modulated by the PNPLA3 rs738409 genotype.This trial was registered at clinicaltrials.gov as NCT01556113.

Plain language summary
Surgery for the treatment of morbid obesity has become a very common intervention due to the increased prevalence of disease and relative ineffective comparative therapies. The aim of this study was to evaluate overall changes in body composition in bariatric surgery patients undergoing a very-low-calorie-diet (VLCD). The study is a prospective analysis on patients who underwent a 2-week period of VLCD prior to bariatric surgery. A total of 60 patients were enrolled. This study demonstrated that although VLCD appears to induce considerable weight loss in a short period of time, the majority of this is attributable to lean body mass (62.2%) rather than fat mass (37.6%). Another notable finding is that greater losses in weight occur largely at the expense of lean body mass rather than fat mass. Authors conclude that a 2-week VLCD is an effective tool for pre-operative weight reduction. However, a large amount of the total weight loss is attributed to a loss of lean body mass.
Abstract
BACKGROUND Fatty liver in obese patients increases the technical difficulty of bariatric surgery. Pre-operative weight loss with a very-low-calorie diet (VLCD) is commonly used to facilitate surgery. Few studies have quantified the systemic effect of rapid pre-operative weight loss on body composition. The objective of this study is to evaluate body composition changes in bariatric surgery patients undergoing a VLCD. METHODS Body composition assessments were performed between August 2017 and January 2019 using dual-energy X-ray absorptiometry immediately before and after a 2-week VLCD at St Vincent's Hospital Melbourne. Data collected prospectively pre- and post-VLCD included total body weight, excess body weight, body mass index (BMI), lean body mass (LBM), fat mass (FM) and bone mineral content (BMC). The pre- and post-operative results were compared. RESULTS Forty-four patients completed both the 2-week VLCD and body composition assessments. Following a 2-week VLCD, patients lost a mean of 4.5 kg (range - 0.3 to 9.5) in a total body weight and 8.8% (range - 0.9 to 17.1) of excess body weight, with a mean reduction in body mass index of 1.6 kg/m2 (range - 0.2 to 3.1). Loss of LBM was 2.8 kg and was significantly greater than loss of FM, 1.7 kg (p < 0.05). BMC changes were insignificant. CONCLUSION A VLCD is an effective tool for pre-operative weight reduction. In this cohort, a large amount of the total weight loss was attributed to a loss of lean body mass. The impact of significant lean body mass loss and its relationship to short- and long-term health outcomes warrants further assessment.

Very low-calorie ketogenic diets (VLCKD) may be an effective way to lose weight. However, the high amount of protein they contain may harm the kidneys, especially in those who already have impaired kidney function. This observational study of 92 obese men and women aimed to evaluate the effect of VLCKD on weight loss in individuals with mild kidney failure, compared to healthy individuals. A VLCKD diet resulted in significantly decreased BMI and body weight, due to a decrease in fat mass and slight decrease in muscle mass. Improvements were seen in blood pressure, indicators for diabetes and cholesterol levels. No changes to kidney or liver function were apparent and only a few minor adverse events were reported. Interestingly a small percentage of individuals with mildly impaired kidney function reported improvements in their condition. It was concluded that VLCKD is a safe and effective way to lose weight in patients with obesity and mild kidney disease. This study could be used by healthcare professionals to consider recommending a VLCKD to patients who are obese and have mild kidney disease.
Abstract
Very low-calorie ketogenic diets (VLCKD) are an effective and increasingly used tool for weight loss. Traditionally considered high protein, ketogenic diets are often looked at with concern by clinicians due to the potential harm they pose to kidney function. We herein evaluated the efficacy and safety of a VLCKD in patients with obesity and mild kidney failure. A prospective observational real-life study was conducted on ninety-two patients following a VLCKD for approximately 3 months. Thirty-eight had mild kidney failure and fifty-four had no renal condition and were therefore designated as control. Anthropometric parameters, bioelectrical impedance and biochemistry data were collected before and at the end of the dietary intervention. The average weight loss was nearly 20% of initial weight, with a significant reduction in fat mass. We report an improvement of metabolic parameters and no clinically relevant variation regarding liver and kidney function. Upon stratification based on kidney function, no differences in the efficacy and safety outcomes were found. Interestingly, 27.7% of patients with mild renal failure reported normalization of glomerular filtrate after dietary intervention. We conclude that, when conducted under the supervision of healthcare professionals, a VLCKD is an effective and safe treatment for weight loss in patients with obesity, including those affected by mild kidney failure.

Bariatric surgery is currently the most effective method of weight loss for individuals with obesity. However sustained weight loss after surgery can be hindered by unhealthy behaviours that have sustained since before the procedure. Motivational, educational, diet and exercise programmes have been shown to help sustain weight loss following surgery. This non-randomised control trial over 12 months, aimed to assess the effects of a motivational, educational diet and exercise programme on fitness and quality of life in 82 individuals following bariatric surgery. The results showed that a diet and exercise programme improved quality of life and fitness. There was an increased daily intake of fruits and vegetables, eating behaviours were improved and there was a greater weight loss in those following the programme. It was concluded that the diet and exercise programme was responsible for behavioural changes that ensured better quality of life and sustained weight loss following surgery. Health care professionals could use this study to understand the need to recommend motivational and educationally based diet and exercise programme to patients following bariatric surgery.
Abstract
INTRODUCTION Unhealthy lifestyles may hinder bariatric surgery outcomes. This non-randomized controlled study aimed to evaluate the effects of an integrated post-operative exercise-based educational and motivational program in improving behaviors, quality of life, anthropometric features, cardiorespiratory and physical fitness in bariatric patients respect to the only surgical intervention. METHODS A group of adult sedentary bariatric patients chose to attend a 12-month exercise program integrated with diet education and motivational support, or to receive usual care. Dietary habits, binge eating disorder, physical activity, obesity-related quality of life, Body Mass Index, waist and hip circumference, VO2max, strength and flexibility were assessed at the start and at the end of the study in both groups. RESULTS On a total of 82 patients enrolled, follow-up measures were obtained from 28 (85.7% females, mean age 38.2±8.7) and 42 (71.4% females, mean age 40.2±9.5) patients included in the intervention and control group, respectively. All the behavioral and physical outcomes improved significantly in the participants to the intervention, while the control group showed lesser changes, especially regarding quality of life and physical fitness. CONCLUSIONS Notwithstanding the self-selection, these results suggest that a timely postoperative behavioral multidisciplinary program for bariatric patients may be effective in establishing healthy behaviors which can lead to better surgery outcomes.
