Reduced appetite with ageing is a key factor that may increase risk of undernutrition. The objective of this study is to determine the impact of innovative plant protein fibre (PPF) products within a personalised optimised diet (PD), a physical activity (PA) programme, and their combination on appetite, and other nutritional, functional and clinical outcomes in community-dwelling older adults in a multi-country randomised controlled intervention trial. One hundred and eighty community-dwelling adults (approximately sixty per trial centre in Germany, Ireland and Italy) aged 65 years and over will be recruited to participate in a 12-week, parallel-group, controlled trial. Participants will be randomised into one of four groups: 1, PD (incorporating two PPF products): 2, PA; 3, PD + PA; and 4, no intervention (control). The primary outcome is appetite measured by visual analogue scales and energy intake from an ad libitum test meal. Secondary outcomes include fasting and postprandial appetite-related gut hormones, Simplified Nutritional Appetite Questionnaire score, body composition, cardiorespiratory fitness, muscle strength, physical function and PA. In addition, self-efficacy, cognitive status, dietary restraint, depressive symptoms and compliance and acceptability of the intervention will be assessed. Metabolomic profiles, RMR, muscle motor unit properties and gut microbiome will also be assessed to explore potential underlying mechanisms. This multi-centre randomised controlled trial will advance knowledge on how PD (incorporating PPF products), PA and their combination influence appetite, nutritional status and related health outcomes in community-dwelling older adults and contribute to the prevention of undernutrition.

There is an urgent need to develop sustainable and impactful interventions to mitigate the high risk of diet-related non-communicable diseases (diet-NCDs) in South Asians living in high-income countries. The current study using a co-design methodology aimed to identify community-led intervention components (solutions) to address barriers and enablers of disease-promoting dietary and physical activity behaviours in New Zealand South Asians. Data were collected from South Asian immigrants aged 25–59 years via three focus group discussions (n = 21) and 10 telephone or face-to-face interviews between 2018 and 2019. The thematic analysis resulted in identifying 22 barrier and enabler codes and 12 solution codes which were summarised under five themes. The key solutions (intervention components) to mitigate the identified target behaviours were providing recipes for using local vegetables in South Asian cuisine, information on the nutritional quality of frozen vegetables and canned lentils, simple home gardening techniques, the saturated fat content of dairy foods, interpreting nutrition labels, optimal portion sizes of foods, and framing low-fat messages positively. Similarly, group-based activities with peer support such as walking, cultural dancing and community sports like cricket, football, and tennis were the identified solutions to increase physical activity levels. The identified solutions for health promoting dietary habits and physical activity levels could be part of any targeted multicomponent health promoting programme to reduce the risk of diet-NCDs in South Asian immigrants.

Interventions aiming to reduce social inequalities of weight status in adolescents usually focus on lifestyle behaviours, but their effectiveness is limited. This study analysed the effect of achieving levels of dietary intake (DI) and/or physical activity (PA) guidelines on reducing social inequalities in weight status among adolescents. We included adolescents from the PRomotion de l’ALIMentation et de l’Activité Physique – INÉgalité de Santé (PRALIMAP-INÈS) trial with weight status data available at baseline and 1-year follow-up (n 1130). PA and DI were measured using the International Physical Activity Questionnaire and a validated FFQ, respectively. We estimated the likelihood of a 1-year reduction in BMI z-score (BMIz) and population risk difference (PRD) under hypothetical DI and PA levels and socio-economic status using the parametric G-formula. When advantaged and less advantaged adolescents maintained their baseline DI and PA, we found social inequalities in weight status, with a PRD of a 1-year reduction in BMIz of −1·6 % (–3·0 %, −0·5 %). These inequalities were not observed when less advantaged adolescents increased their proportion of achieving DI guidelines by 30 % (PRD = 2·2 % (–0·5 %, 5·0 %)) unlike the same increase in PA (PRD = −3·9 % (–6·8 %, −1·3 %)). Finally, social inequalities of weight status were not observed when levels of achievement of both PA and DI guidelines increased by 30 % (PRD = 2·2 % (–0·5 %, 4·0 %)). Enhancing DI rather than PA could be effective in reducing social inequalities in weight status among adolescents. Future interventions aiming to reduce these inequalities should mostly target DI to be effective.

People with polycystic ovary syndrome (PCOS) have higher weight gain and psychological distress compared to those without PCOS(1). While COVID-19 restrictions led to population level adverse changes in lifestyle, weight gain and psychological distress(2), their impact on people with PCOS is unclear. The aim of this study was to investigate the impact the 2020 COVID-19 restrictions had on weight, physical activity, diet and psychological distress for Australians with PCOS. Australian reproductive-aged women participated in an online survey with assessment of weight, physical activity, diet and psychological distress. Multivariable logistic and linear regression were used to examine associations between PCOS and residential location with health outcomes. On adjusted analysis, those with PCOS gained more weight (2.9%; 95% CI; 0.027–3.020; p = 0.046), were less likely to meet physical activity recommendations (OR 0.50; 95% CI; 0.32–0.79; p = 0.003) and had higher sugar-sweetened beverage intake (OR 1.74; 95% CI 1.10–2.75; p = 0.019) but no differences in psychological distress compared to women without PCOS. People with PCOS were more adversely affected by COVID-19 restrictions, which may worsen their clinical features and disease burden. Additional health care support may be necessary to assist people with PCOS to meet dietary and physical activity recommendations.

Patients with inflammatory bowel disease (IBD) have higher risk of developing cardiometabolic diseases due to chronic gut and systemic inflammation which promotes atherogenesis. Adopting healthy lifestyle habits can prevent development of cardiometabolic diseases, but can be challenging for people with IBD. The IBD exercise and diet (IBDeat) habits study describes the lifestyle habits and cardiometabolic disease risk factors of adults with IBD in Aotearoa, New Zealand (NZ).

This is a cross-sectional study including adult NZ IBD patients recruited online via Crohn’s and Colitis NZ and Dunedin hospital from 2021 to 2022. An online questionnaire collected demographics, smoking status, comorbidities, medications, disease severity scores, quality of life, physical activity, and dietary intake. The Dunedin cohort had physical measurements taken including anthropometrics, handgrip strength, blood pressure, body composition (bioelectrical impedance), blood nutritional markers, and faecal calprotectin. Data were compared to established reference values and linear regression analysis investigated associations between lifestyle habits and cardiometabolic risk factors. The study received University of Otago ethical approval (reference: H21/135). A total of 213 adults with IBD (54% Crohn’s disease; 46% ulcerative colitis) completed the online questionnaire and a subset of 102 from Dunedin provided physical measurements. Participants characteristics were: median age 37 (IQR 25, 51) years, 71% female, 82% NZ European, 4% smokers, and 1.4% had active IBD. Thirty-five percent of participants had at least one comorbidity and 34% of participants had poor quality of life. Known dietary risk factors associated with cardiometabolic diseases were common: low intakes of vegetables (77%), fruit (51%), fibre (35%) and high intakes of total fat (84%) and saturated fat (98%). Physical activity recommendations were met by 61% of participants and 63% reported barriers to being more active from fatigue (63%) and joint pain (54%). Other cardiometabolic risk factors were common in the Dunedin cohort: high LDL (79%) and total cholesterol (76%), central adiposity (64%), high body fat percentage (44%), high blood pressure (26%), and low handgrip strength (25%). Regression analysis showed that vegetable (per serve) and carbohydrate (per 5% of total daily energy intake (TE)) were associated with 0.22 mmol/L (95%CI 0.43, 0.013) and 0.20 mmol/L (95%CI 0.34, 0.057) lower LDL cholesterol. Discretionary food items were associated with higher LDL cholesterol, 0.11 mmol/L per daily serve (95%CI 0.028, 0.19). A 5% difference in TE intake from carbohydrate was associated with 1.11% (95%CI 2.22%, 0.0038%) lower body fat percentage while protein was associated with 3.1% (95%CI 0.81%, 5.39%) higher body fat percentage. Physical activity had weak associations with cardiometabolic disease risk factors. Adults with IBD have multiple modifiable risk factors for cardiometabolic diseases. Vegetable and carbohydrate intake were associated with lower LDL cholesterol concentration while discretionary food items showed otherwise. Protein intake was associated with higher body fat percentage.

Polycystic Ovary Syndrome PCOS is an endocrine disorder affecting 8 to 13% of reproductive aged women(1). Dietary and physical activity changes are the first-line therapy to assist with symptom and weight management and to reduce the risk of reproductive, metabolic and psychological comorbidities(2). However, women with PCOS have a higher weight, experience weight gain, and a higher prevalence of living in a larger body. Health care professionals (HCPs) play a crucial role in delivering diet and physical activity advice for people with PCOS. Thus, the aim of this systematic review is to understand the barriers, facilitators, experiences, and perceptions of engagement and compliance with diet and physical activity modifications in people with PCOS and in HCPs providing or referring people with PCOS to diet and physical activity modifications. A mixed-method systematic review was conducted with quantitative studies narratively synthesised and all studies thematically analysed. There were 68 eligible papers, including n = 59 (n = 5198) people with PCOS and n = 17 (n = 2,622) HCPs. Several themes were identified as impacting people with PCOS’ ability to make diet and physical activity changes. HCP education on PCOS management through diet and physical activity was viewed by HCPs and people with PCOS to be inadequate, further impacting the quality of care and health outcomes. Dietary and physical activity advice delivered by a multidisciplinary team, including dietitians, was identified as a key component for change. Both people with PCOS and HCPs agreed that there was a need for individualised and PCOS-specific diet and physical activity advice. However, HCPs viewed that there was limited evidence supporting these recommendations and a lack of time to deliver this care. Weight stigma was identified as impacting both those in larger and smaller bodies with PCOS, reducing the quality of care and affecting self-perception and mental health. People with PCOS perceived that diet and physical activity are overly focused on weight loss and fertility, independent of their own personal motivations and goals. Systemic changes, including receiving diet and physical activity advice that meet the individual’s needs, are necessary for leading to long-term sustainable changes and improvements in health outcomes. A multidisciplinary team approach and an overhaul of HCPs’ perceptions and mentality of weight and weight-centric care for those with PCOS are essential in delivering effective diet and physical activity advice.

A narrative of decline dominates the ageing process in the Global North. At the same time, older people have shared more positive stories of ageing, particularly with respect to their leisure practices. I explore this tension by drawing on an interview-based study with people playing walking football in the United Kingdom. My contention is that older people express multiple meanings of ageing that disturb deficit-focused cultural scripts of later-life, albeit in ways that can be fraught with tensions and contradictions. First, I explore how older people cultivate an alternate identity departing from assumptions of loneliness and degradation, with walking football providing an opportunity to develop friendships and a sense of belonging. Second, older people emphasise their own (good) health and the embodied demands of walking football, yet in doing so, can reinforce ageist discourses by distinguishing themselves from the inactive and isolated (older) other. Third, older people reflect on their current and future involvement in walking football in positive ways. However, through attending to the temporal character of their experiences, I show how, whilst older people express a desire to continue participation, this is threatened by the realities of their ageing bodies in ways that align with deficit framings of later-life. I conclude by calling for recognising the multiplicity of older people's experiences and exercising caution about reproducing over-simplistic and sweeping celebrations of ageing.

Soft drink consumption has become a highly controversial public health issue. Given the pattern of consumption in China, sugar-sweetened beverage is the main type of soft drink consumed. Due to containing high levels of fructose, a soft drink may have a deleterious effect on handgrip strength (HGS) due to oxidative stress, inflammation and insulin resistance. However, few studies show an association between soft drink consumption and HGS in adults. We aimed to investigate the association between soft drink consumption and longitudinal changes in HGS among a Chinese adult population. A longitudinal population-based cohort study (5-year follow-up, median: 3·66 years) was conducted in Tianjin, China. A total of 11 125 participants (56·7 % men) were enrolled. HGS was measured using a handheld digital dynamometer. Soft drink consumption (mainly sugar-containing carbonated beverages) was measured at baseline using a validated FFQ. ANCOVA was used to evaluate the association between soft drink consumption and annual change in HGS or weight-adjusted HGS. After adjusting for multiple confounding factors, the least square means (95 % CI) of annual change in HGS across soft drink consumption frequencies were −0·70 (–2·49, 1·09) for rarely drinks, −0·82 (–2·62, 0·97) for < 1 cup/week and −0·86 (–2·66, 0·93) for ≥ 1 cup/week (Pfor trend < 0·05). Likewise, a similar association was observed between soft drink consumption and annual change in weight-adjusted HGS. The results indicate that higher soft drink consumption was associated with faster HGS decline in Chinese adults.

Globally, we are currently facing a rapid demographic shift leading to an increase in the proportion of older adults within the population. This raises concerns about the potential increase in age-related diseases and their impact on our ability to provide adequate health and end-of-life care. To apply appropriate interventions, understanding the changes that happen with ageing becomes essential. Ageing is often accompanied by a decrease in appetite and physical activity, which may lead to malnutrition, resulting in decreased muscle mass, physical capabilities and independence. To preserve muscle mass, older adults are advised to increase protein intake and physical activity. However, protein’s high satiating effect may cause reduced energy intake. Physical activity is also advised to maintain or enhance older adult’s appetite. This review paper aims to discuss appetite-related changes that occur with ageing and their consequences. In particular, it will focus on investigating the relationship between protein intake and physical activity and their impact on appetite and energy intake in the ageing population. Recent studies suggest that physical activity might contribute to maintaining or enhancing appetite in older adults. Nevertheless, establishing a definitive consensus on the satiating effect of protein in ageing remains a work in progress, despite some promising results in the existing literature.

The classification of internet gaming disorder (IGD) as a mental condition for further study in 2013 marked the emerging recognition of potential mental health issues associated with internet and gaming addiction. The COVID-19 pandemic and the rapid growth of gaming technology have combined to increase internet gaming, resulting in unhealthy lifestyle behaviors, poor sleep quality and psychological distress. Identifying the complex interplay between internet problem use, sleep disorders and psychological distress is crucial. However, it remains unclear how physical activity and self-compassion could improve sleep quality when individuals experience IGD symptoms. The current study, therefore, examined the relationships between IGD, sleep quality, self-compassion, physical activity and psychological distress using a path analysis approach. The study, targeting young adults (N = 283), found that physical activity played a significant role in connecting the variables and supporting the overall fit of the model. The results suggest that interventions targeting individuals with IGD should focus on promoting physical activity participation and developing self-compassion. Future research should continue to investigate the effectiveness of clinical interventions that incorporate self-compassion and physical activity counseling for individuals with IGD.
