While there is a recognised role of optimising lifestyle behaviours such as diet and physical activity in the management of infertility, the best practice for lifestyle management of infertility remains unknown, and factors influencing the lifestyle behaviours of people with infertility are not well understood. The aim of this systematic review is to evaluate the barriers and enablers to a healthy lifestyle in people with infertility, from the perspectives of people with infertility and health professionals, in order to inform optimal behavioural change strategies for lifestyle management of infertility. Ovid MEDLINE(R), PsycINFO, EMBASE, EBM Reviews, and CINAHL Plus were searched from inception to 12th September 2022. Eligible studies were qualitative, quantitative or mixed-methods primary studies which explored barriers and/or enablers to lifestyle for infertility management, from the perspectives of people with infertility and/or health professionals. Two independent reviewers performed quality assessment, using the Centre for Evidence-Based Management Critical Appraisal of a Survey Tool (quantitative and mixed-methods studies) and the Critical Appraisal Skills Programme Qualitative Checklist (qualitative and mixed-methods studies). Data were analysed by inductive thematic analysis with themes mapped to the Capability, Opportunity, Motivation and Behaviour (COM-B) model(1) and Theoretical Domains Framework (TDF)(2). Relevant behaviour change techniques (BCTs)(3) to target the identified enablers and barriers were suggested. After screening 10703 citations and 82 full-texts, 22 studies were included (12 quantitative, 7 mixed-methods and 3 qualitative) with 18 studies including women with infertility (n = 2442), 10 including men with infertility (n = 1372) and 6 including health professionals (n = 261). From the perspectives of people with infertility, themes related to capability (e.g. strategies for behaviour change), opportunity (e.g. limited time, resources and money) and motivation (e.g. interplay between lifestyle and emotional state); themes mapped to 8 TDF domains. From the perspectives of health professionals, themes related to capability (e.g. identification of patients appropriate for lifestyle intervention), opportunity (e.g. mode of delivery) and motivation (e.g. professional responsibility); themes mapped to 6 TDF domains. 34 BCTs were identified across the suggested interventions. This systematic review found that several interacting factors influence lifestyle in people with infertility as well as health professional behaviour with regards to provision of lifestyle interventions for infertility. These factors can be targeted for optimisation of interventions. In light of the limited number of qualitative studies, there is a need for more qualitative research to gain deeper insights into the perspectives of people with infertility and health professionals for further exploration of the complex and interacting factors which shape lifestyle during the fertility journey.

Lockdown measures imposed in Australia to slow the transmission of COVID-19 protected most Australians from the virus(1). In some areas in NSW, specifically Western Sydney areas, more stringent lockdown regulations were implemented from July to September 2021, referred to as local governmental areas (LGAs) of concern(2). Preliminary evidence showed that people’s lifestyle such as dietary and physical activity behaviours and mental health during lockdown were altered from before lockdown(3). However, intermediate and longer-term impacts on nutrition and physical health are unclear, especially in LGAs of concern. We aimed to examine the impacts of the lockdown on nutritional behaviour of residents of Western Sydney. Mixed methods were employed including quantitative surveys such as ASA-24 and qualitative focus groups, using R software for quantitative analysis. Data was collected from 523 survey participants in addition to 42 focus group participants. The sample was representative of age, gender, county of birth and area of residence. Sixty-two percent reported decreases in their physical activity level post-lockdown compared with pre-lockdown, and 15% reported increases in their physical activity level post-lockdown compared with pre-lockdown. Sixty-nine percent reported increases in their physical activity levels post-lockdown compared with during the lockdown, and 12% reported decreases. Self-reported weight increased in 50% of the participants post-lockdown compared with pre-lockdown and decreased in 13% of the participants. Forty percent self-reported a decrease in their body weight post-lockdown compared with during the lockdown while 16% self-reported an increase in their body weight post-lockdown compared with during the lockdown. Food security status was reported as much worse in seven percent of the participants post-lockdown compared with pre-lockdown while being unvaried in 93% of the participants. Food security status remained unvaried post-lockdown compared with during the lockdown in 93% of the participants but much better in six percent. Eating habits were self-reported as much worse by 52% of the participants post-lockdown compared with pre-lockdown and much better by nine percent. Forty-eight percent of the participants self-reported their eating habits as much better post-lockdown compared with during the lockdown and 10% as much worse. COVID-19 lockdown negatively impacted eating behaviours, physical activity and body weight of Western Sydney residents with minimal impacts on food security. Further analyses are required to examine the associations between eating patterns, physical activity, body weight and food security and age, gender, country of birth and area of residence of participants. These findings can later be used to draft policies that can be put in practice in case of future pandemics in Australia, or in the case of other common natural disasters, such as bushfires and floods.

We reviewed the available research and gave an overview of the effects of nutrition education interventions (NEIs) on medical students’ and residents’ knowledge of nutrition, attitudes towards nutrition care, self-efficacy, dietary practices and readiness to offer nutrition care. From 28 May through 29 June 2021, we searched Google Scholar, PubMed, ProQuest, Cochrane and ProQuest to retrieve 1807 articles. After conducting de-duplication and applying the eligibility criteria and reviewing the title and abstract, 23 papers were included. The data were descriptively and narratively synthesised, and the results were displayed as frequencies, tables and figures. Twenty-one interventions were designed to increase participants’ knowledge of nutrition-related topics, and eighteen studies found that nutrition knowledge had significantly improved post-intervention. Only four of the eleven studies that reported on attitudes about nutrition post-intervention showed a meaningful improvement. The self-efficacy of participants was examined in more than half of the included studies (n 13, 56⋅5 %), and eleven of these studies found a significant increase in the participants’ level of self-efficacy to offer nutrition care post-intervention. At the post-intervention point, seven interventions found that dietary and lifestyle habits had significantly improved. The review demonstrated the potential of NEIs to enhance participants’ dietary habits and nutrition-related knowledge, attitudes and self-efficacy. Reduced nutrition knowledge, attitude and self-efficacy scores during the follow-up, point to the need for more opportunities for medical students and residents to learn about nutrition after the intervention.

The presence of body dissatisfaction (BD) in non-Western countries is an important area of empirical enquiry. The results reflect collectivistic and individualistic cultures of Malaysians and Australians, respectively, whereby social approval, social acceptance, and cultural values are of high importance to Malaysians compared with the more liberal attitudes of Australians with respect to health behaviours. This study sought to compare: (1) Australian and Malaysian women on BD, thin ideal internalisation, sociocultural influences, problematic weight-related behaviours, and health behaviours; and (2) the degree to which BD is associated with health behaviours (smoking, alcohol consumption, drug use, and sexual behaviours) across the two cultures. Participants were 428 Australian females and 402 Malaysian females aged 18–25 years old. Australians had higher BD, thin ideal internalisation, family and media influences, restrained eating, and poorer health behaviours, while Malaysians had higher peer influence. There was no difference for bulimic behaviours across the two countries. BD was found to have an association with use of drugs, smoking, and sexual behaviours among Malaysian women, but not for Australian participants. The permeation of Western standards of the thin ideal due to increased industrialisation, Westernisation, and modernisation has brought about bulimic behaviours in Malaysian women, similar to that of Australian women.

Coronavirus disease 2019 (COVID-19) has rapidly spread globally, forcing countries to apply lockdowns and strict social distancing measures. The aim of this study was to assess eating habits and lifestyle behaviours among residents of the Middle East and North Africa (MENA) region during the lockdown. A cross-sectional study among adult residents of the MENA region was conducted using an online questionnaire designed on Google Forms during April 2020. A total of 2970 participants from eighteen countries participated in the present study. During the pandemic, over 30 % reported weight gain, 6·2 % consumed five or more meals per d compared with 2·2 % before the pandemic (P < 0·001) and 48·8 % did not consume fruits on a daily basis. Moreover, 39·1 % did not engage in physical activity, and over 35 % spent more than 5 h/d on screens. A significant association between the frequency of training during the pandemic and the reported change in weight was found (P < 0·001). A significantly higher percentage of participants reported physical and emotional exhaustion, irritability and tension either all the time or a large part of the time during the pandemic (P < 0·001). Although a high percentage of participants reported sleeping more hours per night during the pandemic, 63 % had sleep disturbances. The study highlights that the lockdown due to the COVID-19 pandemic caused a variety of lifestyle changes, physical inactivity and psychological problems among adults in the MENA region.

In the present study, we aimed to describe dietary changes made post-diagnosis and current dietary supplement use by survivors of colorectal cancer (CRC), and explore the underlying motives for these lifestyle habits. Cross-sectional analyses were performed for 1458 stage I–IV CRC survivors of the Patient Reported Outcomes Following Initial Treatment and Long-Term Evaluation of Survivorship (PROFILES) registry, diagnosed between 2000 and 2009. Lifestyle, sociodemographic and clinical information was collected. Prevalence of and motivations for dietary changes and supplement use were assessed. Associations between lifestyle, sociodemographic and clinical variables were analysed by multivariable logistic regression. CRC survivors (57 % male) were on average 70 (sd 9) years of age and diagnosed 7 (sd 3) years ago. Dietary changes post-diagnosis were reported by 36 % of the survivors and current supplement use by 32 %. Motivations for dietary changes were mostly cancer-related (44 % reported ‘prevention of cancer recurrence’ as the main reason), while motivations for supplement use were less frequently related to the cancer experience (38 % reported ‘to improve health and prevent disease in general’ as the main reason). Dietary changes were significantly associated with dietary supplement use (OR 1·5, 95 % CI 1·1, 2·1). Survivors who had received dietary advice, were non-smokers, under 65 years of age, and had no stoma were more likely to have changed their diet. Survivors who were female, had multiple co-morbidities, and no overweight or obesity were more likely to use supplements. In conclusion, many CRC survivors alter their diet post-diagnosis and use dietary supplements, in part for different reasons. Insights into motivations behind these lifestyle habits and characteristics of CRC survivors adopting these habits can improve the tailoring of lifestyle counselling strategies.
