The occurrence of muscle pain in healthcare workers has been attributed to the conditions within which they are working, mainly the load and physical effort that accompanies handling patients and prolonged awkward working postures. Back, neck, shoulder and hand pain have all been reported. Treatments have been extensively studied; however, few provide long-term benefits. Strength exercise and stretching during work hours has been proposed as a therapy and this randomised control trial of 60 healthcare professionals aimed to determine the effect of whole-body stretching (WBS) during rest breaks at work. The results showed that pain in the lower back, neck and knee were most reported by healthcare professions. By attending three 30-minute stretching exercise classes per week participants experienced less muscle pain and used less effort when performing a variety of job associated tasks. It was concluded that stretching during work time may improve feelings of muscle pain in healthcare professionals, however more large-scale research is warranted to confirm these findings. This study could be used by healthcare professionals to recommend stretching exercise to other healthcare workers and to those who perform manual jobs.
Abstract
Background and Objectives: To investigate the effect of whole-body stretching (WBS) exercise during lunch break for reducing musculoskeletal pain and physical exertion among healthcare professionals. Methods: Full-time healthcare professionals working in hospitals with more than one year of experience were invited to participate. Sixty healthcare professionals (age 37.15 ± 3.9 Years, height 1.61 ± 0.04 m, body mass 67.8 ± 6.3 kg, and BMI 26.5 ± 2.1 kg/m2) participated in this single-blinded, two-arm randomized controlled trial (RCT). Participants were divided into WBS (n = 30) and control (n = 30) groups. The WBS group performed a range of stretching exercises targeting the entire body during a lunch break period for 3 times a week for 6 weeks. The control group received an education program. Musculoskeletal pain and physical exertion were assessed using the Nordic musculoskeletal questionnaire and Borg rating of perceived exertion scale, respectively. Results: The 12-month prevalence of musculoskeletal discomfort among all healthcare professionals was highest in the low back region (46.7%), followed by the neck (43.3%), and then the knee (28.3%). About 22% of participants said that their neck discomfort impacted their job, while about 18% reported that their low back pain impacted their job. Results indicate that the WBS and education program had a beneficial impact on pain and physical exertion (p < 0.001). When comparing the two groups, the WBS group experienced a significantly greater decrease in pain intensity (mean difference 3.6 vs. 2.5) and physical exertion (mean difference 5.6 vs. 4.0) compared to an education program only. Conclusions: This study suggests that doing WBS exercises during lunchtime can help lessen musculoskeletal pain and fatigue, making it easier to get through the workday.

Previous research has shown that the use of melatonin by individuals with irritable bowel syndrome (IBS) has improved symptoms and quality of life (QoL) but did not affect sleep. This research has been shown to have some limitations in that it has been conducted in a small number of individuals and did not use the latest IBS diagnostic criteria. This randomised control trial aimed to determine in 136 individuals with IBS with and without sleep disorders the effects of melatonin on IBS score, gastrointestinal (GI) symptoms, QoL, and sleep. The results showed that compared to placebo, the use of melatonin for 8 weeks resulted in improved IBS score and GI symptoms in individuals with and without sleep disorders. Severity and frequency of abdominal pain, satisfaction with bowel habits, disease impacts on life, and stool consistency were all improved, however frequency of defecations was unaffected. Sleep was improved in those with sleep disorders, but not those without. It was concluded that melatonin can be used to improve IBS and QoL in individuals with or without sleep disorders and may also improve sleep in those with sleep disorders and IBS. This study could be used by healthcare professionals to recommend the use of melatonin to individuals with IBS to improve symptoms and QoL.
Abstract
BACKGROUND Irritable bowel syndrome (IBS) is one of the world's most common gastrointestinal (GI) disorders, and current treatments do not meet patients' demands. This study aimed to investigate melatonin's therapeutic effects on IBS score, GI symptoms, quality of life, and sleep parameters in both groups of IBS patients with and without sleep disorders. METHODS In this randomized double-blinded placebo-controlled trial study, 136 patients with a diagnosis of IBS based on ROME IV criteria were enrolled and then divided into two groups respecting having sleep disorders or not. Patients of each group were randomized in a 1:1 ratio to receive melatonin 6 mg daily (3 mg fasting and 3 mg at bedtime) for 2 months (8 weeks). Blocked randomization was used in this process. All patients were evaluated both at the beginning and the end of the trial regarding IBS score, GI symptoms, quality of life, and sleep parameters through valid questionnaires. RESULTS In both groups of patients with and without sleep disorders, a significant improvement was observed in IBS score and GI symptoms, including the severity and the frequency of abdominal pain, the severity of abdominal bloating, satisfaction with bowel habits, disease's impact on patient's life, and stool consistency; however, there was no significant improvement in the frequency of defecations per week. In patients with sleep disorders, significant improvement in sleep parameters, including subjective sleep quality, sleep latency, sleep duration, sleep efficiency, and daytime dysfunction, was observed, while in patients without sleep disorders, there was no significant improvement in sleep parameters. In addition, quality-of-life improvement was observed in a significant number of melatonin recipients compared to placebo in both groups of patients. CONCLUSION Melatonin can be considered an effective treatment for improving IBS score, GI symptoms, and quality of life in IBS patients with and without sleep disorders. It is also effective to improve sleep parameters in IBS patients with sleep disorders. TRIAL REGISTRATION This study has been registered to the Iranian Registry of Clinical Trials (IRCT) with the approval number IRCT20220104053626N2 on the date of 13/02/2022.

Plain language summary
About 60% of patients with major depressive disorder (MDD) do not fully respond to anti-depressant treatments. The microbiota-gut-brain axis is thought to be involved in the development of MDD, making the microbiome a promising target for new treatments. The aim of this double-blind, randomised, placebo-controlled trial, including 50 adult patients with major depressive disorder, was to evaluate the tolerability, acceptability and efficacy of a multi-strain probiotic supplement for 8 weeks as an adjunctive to antidepressant drugs. There were no serious adverse events; all reported non-serious events were of gastrointestinal nature and more common in the probiotic group (it was not reported whether the difference was statistically significant). A high adherence rate of 97.2% suggests a high level of acceptability. Depressive mood symptoms improved significantly more in the probiotic group. Greater improvements in anxiety in the probiotic were also seen in some, but not all anxiety scales. The authors concluded that a multi-strain probiotic supplement is a promising adjunct to anti-depressant treatment in patients with MDD, with high tolerability and acceptability.
Abstract
IMPORTANCE The microbiota-gut-brain axis is a promising target for novel treatments for mood disorders, such as probiotics. However, few clinical trials have been conducted, and further safety and efficacy data are needed to support this treatment approach. OBJECTIVE To provide acceptability and tolerability data and estimates of intervention effect size for probiotics as adjunctive treatment for patients with major depressive disorder (MDD). DESIGN, SETTING, AND PARTICIPANTS In this single-center, double-blind, placebo-controlled pilot randomized clinical trial, adults aged 18 to 55 years with MDD taking antidepressant medication but having an incomplete response were studied. A random sample was recruited from primary and secondary care services and general advertising in London, United Kingdom. Data were collected between September 2019 and May 2022 and analyzed between July and September 2022. INTERVENTION Multistrain probiotic (8 billion colony-forming units per day) or placebo daily for 8 weeks added to ongoing antidepressant medication. MAIN OUTCOMES AND MEASURES The pilot outcomes of the trial were retention, acceptability, tolerability, and estimates of putative treatment effect on clinical symptoms (depression: Hamilton Depression Rating Scale [HAMD-17] and Inventory of Depressive Symptomatology [IDS] scores; anxiety: Hamilton Anxiety Rating Scale [HAMA] and General Anxiety Disorder [GAD-7] scores) to be used as indicators for a definitive trial. RESULTS Of 50 included participants, 49 received the intervention and were included in intent-to-treat analyses; of these, 39 (80%) were female, and the mean (SD) age was 31.7 (9.8) years. A total of 24 were randomized to probiotic and 25 to placebo. Attrition was 8% (1 in the probiotic group and 3 in the placebo group), adherence was 97.2%, and there were no serious adverse reactions. For the probiotic group, mean (SD) HAMD-17 scores at weeks 4 and 8 were 11.00 (5.13) and 8.83 (4.28), respectively; IDS, 30.17 (11.98) and 25.04 (11.68); HAMA, 11.71 (5.86) and 8.17 (4.68); and GAD-7, 7.78 (4.12) and 7.63 (4.77). For the placebo group, mean (SD) HAMD-17 scores at weeks 4 and 8 were 14.04 (3.70) and 11.09 (3.22), respectively; IDS, 33.82 (9.26) and 29.64 (9.31); HAMA, 14.70 (5.47) and 10.95 (4.48); and GAD-7, 10.91 (5.32) and 9.48 (5.18). Standardized effect sizes (SES) from linear mixed models demonstrated that the probiotic group attained greater improvements in depressive symptoms according to HAMD-17 scores (week 4: SES, 0.70; 95% CI, 0.01-0.98) and IDS Self Report scores (week 8: SES, 0.64; 95% CI, 0.03-0.87) as well as greater improvements in anxiety symptoms according to HAMA scores (week 4: SES, 0.67; 95% CI, 0-0.95; week 8: SES, 0.79; 95% CI, 0.06-1.05), but not GAD-7 scores (week 4: SES, 0.57; 95% CI, -0.01 to 0.82; week 8: SES, 0.32; 95% CI, -0.19 to 0.65), compared with the placebo group. CONCLUSIONS AND RELEVANCE The acceptability, tolerability, and estimated effect sizes on key clinical outcomes are promising and encourage further investigation of probiotics as add-on treatment for people with MDD in a definitive efficacy trial.

Benign prostatic hyperplasia (BPH) is a common issue in men older than 40. BPH is accompanied by irritating and obstructive symptoms that sometimes lead to surgery due to lack of recovery. Tamsulosin is an alpha-receptor blocker that is considered a standard treatment for patients. The aim of this study was to investigate the effect of melatonin [a hormone secreted by the pineal gland at night that regulates the sleep-wake cycle] along with standard treatment on improving the BPH urinary symptoms as well as patients’ quality of life due to their urinary problems. This study is a single centre, parallel group randomised, double-blind clinical trial with balanced randomisation. Patients (n = 108) were randomly allocated to one of the two groups. Results show the combination of melatonin and tamsulosin was significantly effective in treating the symptoms of frequency and nocturia in patients with BPH. Authors conclude that their findings can be used to pave the way to improving the symptoms of patients with BPH.
Abstract
PURPOSE to investigate the effect of melatonin along with tamsulosin in improving BPH urinary symptoms. MATERIALS AND METHODS A total of 108 men with BPH symptoms, age of ≥ 50 years, and International Prostate Symptom Score (IPSS) ≥ 8 entered into the parallel group randomized, double-blind clinical trial with balanced randomization. The treatment group received of 3mg melatonin plus 0.4mg tamsulosin and the control group received placebo plus 0.4mg tamsulosin. Patients and physicians were concealed by sealed and opaque envelopes. Symptoms were assessed at baseline and 1 month after treatment. Finally all scores at the initial and end of the study were compared and analyzed using SPSS software. RESULTS This study showed that adding melatonin to the classic treatment of BPH patients with tamsulosin could significantly reduce the likelihood of nocturia by 2.39 times (95% CI: 1.07-5.32, OR = 2.39, p = 0.033) and could also reduce the frequency of urination by 2.59 times (95% CI: 1.15-5.84, OR = 2.59, p = 0.021). There was no statistically significant difference between the two groups in IPSS, intermittency, incomplete emptying, straining, urgency, and weak stream. CONCLUSION Melatonin plus tamsulosin treatment is associated with a significant improvement of nocturia and frequency in patients with benign proststic hyperplasia. However, it is necessary to do more studies.

Efforts to improve pregnancy rates remain largely focused on enhancing the quality of the transferred embryo. However, there is increasing awareness of the potential role of the intra-uterine environment as a determinant for success. The aim of this study was to determine if lactobacilli-loaded vaginal capsules are superior to placebo in improving a vaginal microbiota reported as unfavourable to implantation in women scheduled for fertility treatment. This study is a single-centre, two-arm, double-blinded, randomised controlled study. The study enrolled women aged 18–40 years who were referred to the Fertility Clinic and whose vaginal microbiota prior to fertility treatment had been diagnosed as an unfavourable. Participants (n=77) were randomised in a 1:1 ratio to either lactobacilli-loaded vaginal capsules or placebo. Results did not show any significant effect of treatment with lactobacilli-loaded vaginal capsules on the unfavourable vaginal microbiota profile among women referred to fertility treatment. However, the study showed the highly dynamic nature of the vaginal microbiota, with a spontaneous improvement rate of 34.2% (of the patients) one to three months after the baseline sample. Authors conclude that probiotics use for the improvement of vaginal microbiota should be tempered with some caution. More studies of both the vaginal and endometrial microbiota are required to confirm the efficacy of specific vaginal probiotics before they can be considered as a therapeutic solution.
Abstract
OBJECTIVE To investigate whether treatment with proprietary lactobacilli-loaded vaginal capsules improves an unfavorable vaginal microbiome diagnosed using a commercially available test and algorithm. DESIGN A randomized, double-blinded, placebo-controlled study was conducted in 74 women prior to undergoing fertility treatment at a single university fertility clinic between April 2019 and February 2021. The women were randomly assigned in a 1:1 ratio to receive one vaginal capsule per day for 10 days containing either a culture of more than 108 CFU of Lactobacillus gasseri and more than 108 CFU Lactobacillus rhamnosus (lactobacilli group) or no active ingredient (placebo group). Vaginal swabs for microbiota analysis were taken at enrollment, after treatment and in the cycle following treatment. PARTICIPANTS AND METHODS Women aged 18-40 years who prior to fertility treatment were diagnosed with an unfavorable vaginal microbiota, characterized by either a low relative load of Lactobacillus or a high proportion of disrupting bacteria using the criteria of the IS-pro™ diagnostic system (ARTPred, Amsterdam, the Netherlands), were enrolled in the study. The primary outcome measure was the proportion of women with improvement of the vaginal microbiota after intervention. RESULTS The vaginal microbiota improved after intervention in 34.2% of all participants (lactobacilli group 28.9%, placebo group 40.0%), with no significant difference in the improvement rate between the lactobacilli and placebo groups, RR = 0.72 (95% CI 0.38-1.38). CONCLUSION This study indicates that administering vaginal probiotics may not be an effective means of modulating the vaginal microbiome for clinical purposes in an infertile population. However, a spontaneous improvement rate of 34.2% over a period of one to three months, confirming the dynamic nature of the vaginal microbiota, indicates that a strategy of postponing further IVF treatment to await microbiota improvement may be relevant in some patients, but further research is needed.

Plain language summary
Non-small cell lung cancer (NSCLC) is commonly treated with concurrent chemo- and radiation therapy (CCRT). This treatment often causes acute radiation-induced oesophagitis (ARIE) which can lead to significant weight loss and unplanned treatment delays. This prospective randomised study assessed whether glutamine supplementation may prevent ARIE in advanced NSCLC patients. Patients were randomised to receive either standard treatment (CCRT) with prophylactic oral glutamine, 30 grams/day, or standard treatment alone. The patients in the glutamine group received glutamine for 1 year. Compared with the control group, the oral glutamine supplement group had significantly less severe ARIE, and in those patients who developed ARIE, onset was significantly delayed in the glutamine group. The incidence of weight loss was also significantly reduced in the glutamine group. There was no statistically significant difference in cancer progression-free survival between the two groups (median follow-up period 26.4 months). Glutamine supplementation was well tolerated by all patients. The authors conclude that oral glutamine supplementation has a benefit in delaying onset of and decreasing the severity of ARIE in advanced lung cancer patients undergoing CCRT.
Abstract
BACKGROUND Complications related to concurrent chemoradiotherapy (CCRT) such as acute radiation-induced esophagitis (ARIE) may cause significant morbidity and unplanned treatment delays in patients with advanced non-small cell lung cancer (NSCLC). We designed a prospective randomized study to assess the impact of glutamine (GLN) supplementation in preventing CCRT-induced toxicities of advanced NSCLC patients. METHODS From September 2014 to September 2015, 60 patients diagnosed with NSCLC were included to the study. Thirty patients (50%) received prophylactic powdered GLN orally at a dose of 10 g/8 h. The prescribed radiation dose to the planning target volume was 30 Gy in 2-Gy fractions. The endpoints were radiation-induced esophagitis, mucositis, body weight loss, overall survival and progression-free survival. RESULTS The 60 patients with NSCLC included 42 men and 18 women with a mean age ± standard deviation of 60.3 years ± 18.2 (range, 44-78 years).At a median follow-up of 26.4 months (range 10.4-32.2), all patients tolerated GLN well. A administration of GLN was associated with a decrease in the incidence of grade 2 or 3 ARIE (6.7% vs 53.4% for Gln+ vs Gln-; P = .004). GLN supplementation appeared to significantly delay ARIE onset for 5.8 days (18.2 days vs 12.4 days; P = .027) and reduced incidence of weight loss (20% vs 73.3%; P = .01). DISCUSSION Our study suggests a beneficial effect of oral glutamine supplementation for the prevention from radiation-induced injury and body weight loss in advanced NSCLC patients who receiving CCRT.

Plain language summary
Chronic plaque psoriasis is an immune-mediated disease of the skin and joints. A growing appreciation of the role of the innate immune system in psoriasis pathogenesis stems from the prominent role of inflammatory cytokines and cells associated with innate immunity in the disease and associations observed between psoriasis and genetic variations involved in innate immunity. The aim of this study was to assess changes of the skin microbiome in the setting of a longitudinal phase 3b study of patients receiving up to 2 years of ustekinumab therapy. Results show that prior to treatment, there were minor, body-site specific differences in microbial diversity and composition when comparing lesional with non-lesional skin. Microbial heterogeneity was greater in lesional skin than non-lesional skin. During ustekinumab treatment, the composition of microbiota diverged further between lesional and non-lesional skin across body sites. The divergence observed between lesional and non-lesional skin during ustekinumab treatment varied by body site. Authors conclude that their findings may help inform future study design and it may also have medically relevant implications for diagnostics and therapeutics involving the skin microbiome.
Abstract
Plaque psoriasis, a chronic inflammatory disease primarily affecting the skin, is thought to have a multifactorial etiology, including innate immune system dysregulation, environmental triggers, and genetic susceptibility. We sought to further understand the role of skin microbiota in psoriasis pathogenesis, as well as their response to therapy. We systematically analyzed dynamic microbiota colonizing psoriasis lesions and adjacent nonlesional skin in 114 patients prior to and during ustekinumab treatment in a phase 3b clinical trial. By sequencing the bacterial 16S ribosomal RNA gene from skin swab samples obtained at six anatomical sites, we identified minor, site-specific differences in microbial diversity and composition between pretreatment lesional and nonlesional skin. During therapy, microbial communities within lesional and nonlesional skin diverged, and body-site dispersion increased, reflecting microbial skin site-specificity. Microbiota demonstrated greater pretreatment heterogeneity in psoriatic lesions than in nonlesional skin, and variance increased as treatment progressed. Microbiota colonizing recurrent lesions did not overlap with pretreatment lesional microbiota, suggesting colonization patterns varied between initial and recurrent psoriatic lesions. While plaque psoriasis does not appear to be associated with specific microbes and/or microbial diversity, this large dataset provides insight into microbial variation associated with (i) disease in different body locations, (ii) initial versus recurrent lesions, and (iii) anti-IL12/23 therapy.

Intravenous steroids are the first-line therapy for ulcerative colitis (UC) patients who are hospitalised during a severe UC flare-up. In the 40% of patients who don’t respond to steroids, the drugs ciclosporin and infliximab have been found to be efficient in preventing surgery to remove part or all of the colon, but there is a lack of data on the long-term outcomes of using these medications in UC patients. The aim of this study was to assess long-term outcome of patients included in a randomised trial comparing ciclosporin and infliximab. Between 2007 and 2010, 115 patients with UC that did not respond to steroids were randomised to receive ciclosporin or infliximab in association with azathioprine. Patients were followed to January 2015 or death. After a median follow-up of 5.4 years, colectomy-free survival rates at 1 and 5 years were, respectively, 70.9% and 61.5% in patients who received ciclosporin and 69.1% and 65.1% in those who received infliximab. Long-term colectomy-free survival was independent from initial treatment. However, a higher proportion of patients initially treated with ciclosporin needed a new treatment compared with those who received infliximab first. The researchers concluded that these results further confirm a similar efficacy and good safety profiles of both drugs.
Abstract
OBJECTIVE Ciclosporin and infliximab have demonstrated short-term similar efficacy as second-line therapies in patients with acute severe UC (ASUC) refractory to intravenous steroids. The aim of this study was to assess long-term outcome of patients included in a randomised trial comparing ciclosporin and infliximab. DESIGN Between 2007 and 2010, 115 patients with steroid-refractory ASUC were randomised in 29 European centres to receive ciclosporin or infliximab in association with azathioprine. Patients were followed until death or last news up to January 2015. Colectomy-free survival rates at 1 and 5 years and changes in therapy were estimated through Kaplan-Meier method and compared between initial treatment groups through log-rank test. RESULTS After a median follow-up of 5.4 years, colectomy-free survival rates (95% CI) at 1 and 5 years were, respectively, 70.9% (59.2% to 82.6%) and 61.5% (48.7% to 74.2%) in patients who received ciclosporin and 69.1% (56.9% to 81.3%) and 65.1% (52.4% to 77.8%) in those who received infliximab (p=0.97). Cumulative incidence of first infliximab use at 1 and 5 years in patients initially treated with ciclosporin was, respectively, 45.7% (32.6% to 57.9%) and 57.1% (43.0% to 69.0%). Only four patients from the infliximab group were subsequently switched to ciclosporin. Three patients died during the follow-up, none directly related to UC or its treatment. CONCLUSIONS In this cohort of patients with steroid-refractory ASUC initially treated by ciclosporin or infliximab, long-term colectomy-free survival was independent from initial treatment. These long-term results further confirm a similar efficacy and good safety profiles of both drugs and do not favour one drug over the other.

The microbiome and its effects on health have received plenty of attention and research. A lot less is known about the virome, the collection of viruses in and on our bodies. This pilot observational study looked at the connection between the viruses and bacteria in the guts of patients with Clostridium difficile infection (CDI), compared to healthy controls, and changes and treatment outcomes observed after faecal microbiota transplantation (FMT) compared to vancomycin treatment. The study showed that, compared to healthy household controls, people with CDI had significant viral dysbiosis, in particular higher abundance but lower diversity, richness and evenness of the bacteriophage (a virus that infects bacteria) Caudovirales, the most abundant intestinal bacteriophage in humans. FMT changed both, the composition of the microbiome as well as the virome, whilst antibiotic treatment did not affect the bacteriophage composition. Treatment outcome with FMT depended on changes in Caudivirales. Although a small pilot study, according to the authors, this is the biggest study into the importance of intestinal viruses, and their correlation with the microbiome, in disease and for treatment outcomes. The authors point out that, as this was an observational study, it is not possible to ascertain whether the altered virome is a cause or a consequence of the disease.
Abstract
OBJECTIVE Faecal microbiota transplantation (FMT) is effective for the treatment of recurrent Clostridium difficile infection (CDI). Studies have shown bacterial colonisation after FMT, but data on viral alterations in CDI are scarce. We investigated enteric virome alterations in CDI and the association between viral transfer and clinical outcome in patients with CDI. DESIGN Ultra-deep metagenomic sequencing of virus-like particle preparations and bacterial 16S rRNA sequencing were performed on stool samples from 24 subjects with CDI and 20 healthy controls. We longitudinally assessed the virome and bacterial microbiome changes in nine CDI subjects treated with FMT and five treated with vancomycin. Enteric virome alterations were assessed in association with treatment response. RESULTS Subjects with CDI demonstrated a significantly higher abundance of bacteriophage Caudovirales and a lower Caudovirales diversity, richness and evenness compared with healthy household controls. Significant correlations were observed between bacterial families Proteobacteria, Actinobacteria and Caudovirales taxa in CDI. FMT treatment resulted in a significant decrease in the abundance of Caudovirales in CDI. Cure after FMT was observed when donor-derived Caudovirales contigs occupied a larger fraction of the enteric virome in the recipients (p=0.024). In treatment responders, FMT was associated with alterations in the virome and the bacterial microbiome, while vancomycin treatment led to alterations in the bacterial community alone. CONCLUSIONS In a preliminary study, CDI is characterised by enteric virome dysbiosis. Treatment response in FMT was associated with a high colonisation level of donor-derived Caudovirales taxa in the recipient. Caudovirales bacteriophages may play a role in the efficacy of FMT in CDI.

Nutrition labelling on the front of packaged food is a policy tool to help promote healthier food choices. Current research on the effectiveness of package labelling food-purchasing behaviour is both limited and mixed in results. The aim of this large-scale randomised trial was to compare Australia's new Health Star Rating (HSR) with five other front-of-pack labelling schemes with a focus on usability and impact on food choices. The 1578 participants were randomised to one of six experimental groups or the control group and food purchases were tracked by a smartphone application for four weeks. This study demonstrated that the HSR system was as good as other front-of-pack labelling schemes in many outcomes, and superior in terms of usefulness, however there was no evidence to show HSR improved food purchasing behaviour. Based on these results, the authors conclude that various package labelling systems are effective and HSR is one they would recommend.
Abstract
BACKGROUND Front-of-pack nutrition labelling may support healthier packaged food purchases. Australia has adopted a novel Health Star Rating (HSR) system, but the legitimacy of this choice is unknown. OBJECTIVE To define the effects of different formats of front-of-pack labelling on the healthiness of food purchases and consumer perceptions. DESIGN Individuals were assigned at random to access one of four different formats of nutrition labelling-HSR, multiple traffic light labels (MTL), daily intake guides (DIG), recommendations/warnings (WARN)-or control (the nutrition information panel, NIP). Participants accessed nutrition information by using a smartphone application to scan the bar-codes of packaged foods, while shopping. The primary outcome was healthiness defined by the mean transformed nutrient profile score of packaged foods that were purchased over four weeks. RESULTS The 1578 participants, mean age 38 years, 84% female recorded purchases of 148,727 evaluable food items. The mean healthiness of the purchases in the HSR group was non-inferior to MTL, DIG, or WARN (all p < 0.001 at 2% non-inferiority margin). When compared to the NIP control, there was no difference in the mean healthiness of purchases for HSR, MTL, or DIG (all p > 0.07), but WARN resulted in healthier packaged food purchases (mean difference 0.87; 95% confidence interval 0.03 to 1.72; p = 0.04). HSR was perceived by participants as more useful than DIG, and easier to understand than MTL or DIG (all p < 0.05). Participants also reported the HSR to be easier to understand, and the HSR and MTL to be more useful, than NIP (all p < 0.03). CONCLUSIONS These real-world data align with experimental findings and provide support for the policy choice of HSR. Recommendation/warning labels warrant further exploration, as they may be a stronger driver of healthy food purchases.
