Sustainability and cost of typical and heart-healthy dietary patterns in Australia.

Study objective: The aim was to quantify and compare the environmental and financial impact of two diets: a heart-healthy Australian diet (HAD) and the typical Australian diet (TAD). Design: The study involved a secondary analysis of two modelled dietary patterns used in a cross-over feeding trial. Setting: The evaluation focused on two-week (7-day cyclic) meal plans designed to meet the nutritional requirements for a reference 71-year-old male (9000 kJ) for each dietary pattern. Main outcome measures: The environmental footprint of each dietary pattern was calculated using the Global Warming Potential (GWP*) metric, taking into account single foods, multi-ingredient foods, and mixed dishes. Prices were obtained from a large Australian supermarket. Results: The HAD produced 23.8 % less CO2 equivalents (CO2e) per day (2.16 kg CO2e) compared to the TAD (2.83 kg CO2e per day). Meat and discretionary foods were the primary contributors to the environmental footprint of the TAD, whereas dairy and vegetables constituted the largest contributors to the HAD footprint. However, the HAD was 51 % more expensive than the TAD. Conclusion: Transitioning from a TAD to a HAD could significantly reduce CO2 emissions and with benefits for human health and the environment. Affordability will be a major barrier. Strategies to reduce costs of convenient healthy food are needed. Future studies should expand the GWP* database and consider additional environmental dimensions to comprehensively assess the impact of dietary patterns. Current findings have implications for menu planning within feeding trials and for individuals seeking to reduce their carbon footprint while adhering to heart-healthy eating guidelines.

How do plant-based milks compare to cow's milk nutritionally? An audit of the plant-based milk products available in Australia.

AIM: This cross-sectional study aims to explore the nutritional composition, cost, country of origin and fortification status of plant-based milk products available for purchase in Illawarra supermarkets and make various comparisons between types of plant-based milks and cow's milk. METHODS: Plant-based milk information was collected from nutrition information panels on packaging and manufacturer websites. Product ingredient lists, including fortifiers, were analysed to estimate the nutrient composition of the identified plant-based milks, including nutrients beyond those listed by manufacturers. Descriptive statistics were used to summarise the characteristics of the plant-based milks identified in the audit. For non-normally distributed data, a Kruskal-Wallis H test with pairwise multiple comparisons and a Bonferroni adjustment were undertaken to explore the differences between various types of plant-based milk and cow's milk. RESULTS: One hundred twenty-nine plant-based milk products were identified in the audit, primarily almond, oat and soy-based beverages. Of these, 80.6% were fortified with calcium; however, fortification with other micronutrients was less common, ranging from 27.1% being fortified with vitamin B12 and 3.1% being fortified with iodine. The median plant-based milk cost was AU$3.5/L (Q1-Q3: AU$2.8-4.5/L) and 87.6% of products were Australian made. Overall, particularly due to low fortification rates, plant-based milks identified in the audit had significantly lower levels of protein, sugar, iodine, phosphorus, zinc and vitamins A, B2 and B12 compared to cow's milk. However, there was no significant difference in protein content between soy milk and cow's milk. CONCLUSIONS: The nutritional content of plant-based milks identified in this audit varied, and in most instances, Australian plant-based milks were found to be nutritionally different to cow's milk.

Supporting the nutrition-related health and well-being of people experiencing socio-economic disadvantage: Findings from a national survey.

BACKGROUND: People experiencing socio-economic disadvantage face significantly higher rates of diet-related health inequities. This study aimed to explore barriers, opportunities and potential solutions in providing food and nutrition services to people experiencing socio-economic disadvantage from the perspective of services providers. The present study is part of a broad co-design model to improve service provision for people experiencing socio-economic disadvantage. METHODS: A cross-sectional online survey involving 33 open and closed-ended questions was distributed to Australian governmental and non-governmental organisations providing nutrition-related support to people experiencing socio-economic disadvantage aged 16 years and over. Data were analysed using frequency distributions and conceptual content analyses. RESULTS: Sixty-eight responses were analysed. Services are predominantly offered by charitable organisations (90%), funded through private donations (66%) and reliant on volunteers (100%). Barriers to supporting clients' nutrition needs include financial constraints, limited community engagement, understaffing, insufficient resources and knowledge gaps. Opportunities and solutions for enhancing support include increasing government funding, advocacy initiatives, stronger community collaboration and more holistic, customised services. Proposed recommendations include establishing purpose-built facilities or wrap-around services to expand access to health services, life skills, training and educational programs. CONCLUSIONS: Services face challenges including volunteer reliance, limited resources and inadequate government support, hindering food provision. Client barriers include transportation costs and lack of social support. With dedicated financial support, services can offer comprehensive assistance, including community spaces, staffing, health and social services and training. Community partnerships can maximise funding impact. Solutions must address overall well-being and broader social determinants such as income inequality and housing.

Higher anthocyanin intake is associated with lower depressive symptoms in adults with and without major depressive disorder.

Background: Major depressive disorder (MDD) is a significant cause of disability globally and an emerging body of evidence suggests that dietary components, including flavonoids, may impact depression-related biochemical pathways. Further research that characterizes dietary intake of flavonoids in diverse population groups, including people with MDD and explores the relationship between flavonoid intake and depression is needed. This study aimed to determine dietary flavonoid and subclass intake and assess the association with depressive symptomatology in a sample of adults with and without MDD. Methodology: Participants with and without MDD (determined using DSM 5) completed the Depression, Anxiety, and Stress Scale-21 (DASS-21). Diet history interviews were analyzed using PhenolExplorer to quantify flavonoid subclasses (flavan-3-ols, flavonols, anthocyanins, flavones, flavanones, isoflavones), and total flavonoid intake. Independent t-tests and linear regression, adjusting for age, sex, and BMI were performed. Results: Participants (n = 93; 75% female) had a mean age of 26.0 ± 8.2 years. Participants with MDD had significantly higher DASS-depression scores (n = 44; DASS-depression 27.3 ± 9.8) compared to participants without MDD (n = 49; DASS-depression 3.1 ± 4.4; p < .001). Intakes of total flavonoids and subclasses were similar between groups, except for anthocyanins where participants with MDD reported lower intakes of anthocyanins compared to participants without MDD (median intake: 0.08 mg/day and 11.6 mg/day, respectively; p = .02). In the total sample, higher anthocyanin intake was associated with lower DASS-depression score (B = -4.1; SE = 1.8; 95% CI [-7.7, -0.4]; p = .029). Conclusion: Intake of total flavonoids and most subclasses were similar between people with and without MDD. However, a dietary deficit of anthocyanins (found in purple/red fruits and vegetables) was evident in participants with MDD, and higher anthocyanin intake was associated with lower depressive symptomatology in the total sample. Further research in larger samples is warranted to explore if the documented association is independent of MDD status.

Association between food insecurity status, campus food initiative use and diet quality in Australian university students.

AIMS: University students may experience food insecurity due to financial constraints, reducing the quality of their diet. This study aimed to identify students at higher risk of food insecurity, their engagement with on-campus food initiatives and evaluate the relationship between food insecurity and a validated index of diet quality. METHODS: A cross-sectional online survey used the six-item Household Food Security Survey Module to assess food insecurity. Total diet quality and subscale scores for eight food groups were measured using the Australian Recommended Food Score (range 0-73). Univariate and multivariate regression identified groups at risk of food insecurity, their engagement with campus food initiatives and relationship with diet quality scores. RESULTS: Of student respondents (n = 197), over half (54%) experienced food insecurity (14% mild, 23% moderate and 18% severe food insecurity). Male students and students not living with parents were at significantly higher risk. Food-insecure students were significantly more likely to use the campus food pantry (odds ratio = 2.3 [95% confidence interval = 1.286-4.142]; p = 0.005) but not a campus community garden. The mean diet quality score was 32.9 (standard deviation = 8.9). Food-insecure students reported a mean diet quality score over three points lower than food-secure respondents (B = -3.5 [95% confidence interval = -6.0 to -1.0]; p = 0.006), with significantly lower fruit and vegetable subscale scores. CONCLUSIONS: Results suggest a high occurrence of food insecurity and poor dietary quality in university students. Despite high levels of engagement with the campus food pantry, the poor diet quality of food-insecure students suggests an urgent need for greater university-led interventions to improve students' dietary intake.

Expansion of an Australian food composition database to estimate plant and animal intakes.

Despite evidence for favourable health outcomes associated with plant-based diets, a database containing the plant and animal content of all foods eaten is required to undertake a reliable assessment of plant-based diets within a population. This study aimed to expand an existing Australian food database to include the plant and animal content of all whole foods, beverages, multi-ingredient products and mixed dishes. Twenty-three plant- and animal-based food group classifications were first defined. The food servings per 100 g of each product were then systematically calculated using either a recipe-based approach, a food label-based approach, estimates based on similar products or online recipes. Overall, 4687 (83·5 %) foods and beverages were identified as plant or plant-containing products, and 3701 (65·9 %) were animal or animal-containing products. Results highlighted the versatility of plant and animal ingredients as they were found in various foods across many food categories, including savoury and sweet foods, as well as discretionary and core foods. For example, over 97 % of animal fat-containing foods were found in major food groups outside the AUSNUT 2011-2013 'fats and oils' group. Surprisingly, fruits, nuts and seeds were present in a greater percentage of discretionary products than in core foods and beverages. This article describes a systematic approach that is suitable for the development of other novel food databases. This database allows more accurate quantitative estimates of plant and animal intakes, which is significant for future epidemiological and clinical research aiming to investigate plant-based diets and their related health outcomes.

"I Always Buy the Purple Ones If I See Them": Socioecological Factors Influencing Anthocyanin-Rich Food Consumption for Cognitive Health in Older Adults.

Despite the positive relationship between anthocyanin-rich foods and cognitive health, a dietary deficit exists in older adults. Effective interventions require an understanding of people's dietary behaviors situated in social and cultural contexts. Therefore, the aim of this study was to explore older adults' perceptions about increasing their consumption of anthocyanin-rich foods for cognitive health. Following an educational session and the provision of a recipe and information book, an online survey and focus groups with Australian adults aged 65 years or older (n = 20) explored the barriers and enablers towards eating more anthocyanin-rich foods and potential strategies to achieve dietary change. An iterative, qualitative analysis identified the themes and classified the barriers, enablers and strategies onto the Social-Ecological model levels of influence (individual, interpersonal, community, society). Enabling factors included a desire to eat healthily, taste preference and familiarity of anthocyanin-rich foods (individual), social support (community), and the availability of some anthocyanin-rich foods (society). The barriers included budget, dietary preferences and motivation (individual), household influences (interpersonal), limited availability and access to some anthocyanin-rich foods (community) and the cost and the seasonal variability (society). The strategies included increasing individual-level knowledge, skills, and confidence in utilizing anthocyanin-rich foods, educational initiatives about the potential cognitive benefits, and advocating to increase access to anthocyanin-rich foods in the food supply. This study provides for the first time, insight into the various levels of influence impacting older adults' ability to consume an anthocyanin-rich diet for cognitive health. Future interventions should be tailored to reflect the barriers and enablers and to provide targeted education about anthocyanin-rich foods.

Association between vitamin D status and lifestyle factors in Brazilian women: Implications of Sun Exposure Levels, Diet, and Health.

Background: Vitamin D deficiency has been documented to be prevalent, even in low latitude regions; and this may be related to sun exposure behaviors. The aim of the current study was to assess the association between serum 25-hydroxyvitamin D [25(OH)D] concentrations and lifestyle-related factors in a sample of Brazilian women living at latitude 21º 8' S. Methods: A cross-sectional study was undertaken in 101 women aged 35 years or older in July 2019 to assess the association between 25(OH)D concentration and level of exposure to ultraviolet radiation (UVR), smoking habits, alcohol consumption, and physical activity levels. Age, body mass index (BMI), and postmenopausal status were investigated. Findings: According to the slope coefficient for individual daily UVR levels, the concentration of 25(OH)D increased by 5 nmol / L for each extra Standard Erythema Dose of UVR, regardless of age and BMI (p < 0·001). Postmenopausal women had a significantly higher mean concentration of 25(OH)D (p = 0·01), higher UVR exposure (p = 0·01) and lower BMI (p = 0·005) compared with younger women, independent of other confounders including smoking, alcohol, occupation and physical activity. Interpretation: Although postmenopausal women from Brazil had higher mean concentrations of 25(OH)D than younger women, more studies are necessary to understand how sun exposure and lifestyle variables interfere with these levels. These findings have important public health implications since they suggest that vitamin D deficiency in older age is not inevitable. Funding: This study was funded by an award received by Universities Global Partnership Network - UGPN. KVSS and SLO receive scholarship from CAPES, Brazilian Ministry of Education. HR receives a productivity grant from CNPq.

Anthocyanin intake is associated with improved memory in older adults with mild cognitive impairment.

Research on the role of dietary anthocyanins in preventing cognitive decline in older adults shows promise. This study investigated the association between usual anthocyanin intake and indices of memory and cognition in 40 older adults diagnosed with mild cognitive impairment that were recruited to a randomized clinical trial. It was hypothesized that daily anthocyanin intake would be similar to healthy older adults and that higher anthocyanin intake would be associated with better cognitive performance. Cognitive performance was assessed using a battery of tests including the Rey Auditory Verbal Learning Test (RAVLT). Dietary intake was assessed through 3-day food records and anthocyanin intake was quantified using the PhenolExplorer food composition database. Multivariate linear regression compared differences in cognitive performance between higher (>10 mg/d) and lower consumers (<10 mg/d). Overall, participants had low median intake of anthocyanins (5.3; interquartile range [IQR], 32.1 mg/d), with the lower consumer group eating negligible anthocyanins (median, 0.13; IQR, 1.5 mg/d), and the higher consumer group eating above the national average (median, 35.5; IQR, 71.5 mg/d). On the RAVLT, the higher anthocyanin consumer group recalled a greater number of words after a short delay and a distracter task (B, 2.07; standard error [SE], 0.93; 95% confidence interval [CI], 0.18-3.96; P = .03) and longer delay of 20 minutes (B, 2.68; SE, 1.11; 95% CI, 0.43-4.94; P = .02); and forgot less words after a long delay of 20 minutes (B, -2.63; SE, 0.63; 95% CI, -3.90 to -1.35; P< .001). Further investigation of the protective role of the usual consumption of dietary anthocyanins for memory and cognition in pathological and normal aging appears warranted. Trial registration: This cross-sectional study uses baseline data from a randomized controlled trial registered with the Australian New Zealand Clinical Trials Registry (ACTRN12618001184268).

Nutrition programmes for individuals living with disadvantage in supported residential settings: a scoping review.

OBJECTIVE: Health inequities such as chronic disease are significantly higher among individuals living with disadvantage compared with the general population and many are reported to be attributable to preventable dietary risk factors. This study provides an overview of the current nutrition interventions for individuals living with extreme disadvantage, in supported residential settings, to develop insights into the development and implementation of policies and practices to promote long-term nutritional health and well-being. DESIGN: A scoping review searched Scopus, ProQuest, CINAHL Plus, MEDLINE, and Web of Science databases using the terms 'resident', 'nutrition', 'disadvantage', 'intervention' and their synonyms, with particular emphasis on interventions in residential settings. SETTING: Residential services providing nutrition provision and support. PARTICIPANTS: People experiencing extreme disadvantage. RESULTS: From 5262 articles, seven were included in final synthesis. Most interventions focused on building food literacy knowledge and skills. Study designs and outcome measures varied; however, all reported descriptive improvements in behaviour and motivation. In addition to food literacy, it was suggested that interventions need to address behaviour and motivations, programme sustainability, long-term social, physical and economic barriers and provide support for participants during transition into independent living. Socio-economic issues remain key barriers to long-term health and well-being. CONCLUSIONS: In addition to food literacy education, future research and interventions should consider utilising an academic-community partnership, addressing nutrition-related mental health challenges, motivation and behaviour change and a phased approach to improve support for individuals transitioning into independent living.

Prevalence of hospital-acquired malnutrition and modifiable determinants of nutritional deterioration during inpatient admissions: A systematic review of the evidence.

BACKGROUND: Malnutrition affects between 20% and 50% of hospital inpatients on admission, with further declines expected during hospitalisation. This review summarises the existing literature on hospital-acquired malnutrition that examines the magnitude of nutritional deterioration amongst adult inpatients and identifies preventable barriers to optimising nutrition support during episodes of care. METHODS: A systematic review was conducted to answer the question: Among adult hospital inpatients, the presence of which modifiable factors contribute to hospital-acquired malnutrition? A database search was conducted between the 24 April and 30 June 2020 using CINAHL, MEDLINE, Scopus and PubMed databases according to a protocol registered with PROSPERO (CD42020182728). In addition, issues of the 10 top clinical nutrition journals published during the period of from 1 April 2015 to 30 March 2020 were hand-searched. RESULTS: Fifteen articles were eligible for inclusion from a total of 5944 retrieved abstracts. A narrative synthesis of evidence was completed because of the high level of heterogeneity in methodologies. Nutritional deterioration is common among previously well-nourished and nutritionally compromised patients, with studies reporting that 10%-65% of patients experienced nutritional decline. Frequently reported barriers were mealtime interruptions, meal dissatisfaction, procedure-related fasting, effects of illness or treatment, chewing difficulties, poor appetite and malnutrition as a low clinical priority. CONCLUSIONS: The findings of this review support the need for routine nutritional risk screening throughout each hospital admission with hospital-acquired malnutrition affecting up to 65% of inpatients. Clear establishment of the roles and responsibilities of each member within multidisciplinary healthcare teams in the provision of nutrition care and cost-benefit analyses are recommended to demonstrate the effectiveness of changes to models of care.

The effectiveness of nutrition interventions in improving frailty and its associated constructs related to malnutrition and functional decline among community-dwelling older adults: A systematic review.

BACKGROUND: The present study aimed to evaluate the effectiveness of nutrition interventions on frailty and factors related to frailty, including malnutrition, sarcopenia and functional ability, among community dwelling older adults. A secondary aim was to synthesise current clinical guidelines for the identification and management of frailty, and then identify whether they aligned with the findings of the literature review. METHODS: A systematic literature review was undertaken using four electronic databases to identify randomised controlled clinical trials that assessed the effect of nutrition interventions on frailty and outcomes related to frailty in community-dwelling older adults (PROSPERO #CRD42017069094). The quality of the included studies was appraised. A rapid review was conducted using the Google Scholar database to identify existing clinical recommendations relating to the second aim. RESULTS: The search strategy identified 13 studies. Multifactorial interventions with nutritional education and protein-energy supplementation improved frailty stratus and physical performance in 75% and 58% of studies, respectively. Weight and nutritional status improved in 80% of studies that used oral nutritional support. The recommended process for clinical management of frailty involves screening, followed by full assessment using validated instruments and the development of a comprehensive management plan with a multidisciplinary team. CONCLUSIONS: Multifactorial interventions were found to be more effective than nutrition intervention alone for improving frailty and physical performance. Protein-energy supplementation tended to be effective only in malnourished older adults. The results were inconclusive for the use of micronutrient supplementation for frailty and outcomes related to frailty. Existing clinical guidelines are aligned with the evidence recommending comprehensive interventions to improve frailty.

Effect of South Africa's interim mandatory salt reduction programme on urinary sodium excretion and blood pressure.

South Africa implemented legislation in June 2016 mandating maximum sodium (Na) levels in processed foods. A pre-post impact evaluation assessed whether the interim legislative approach reduced salt intake and blood pressure. Baseline Na intake was assessed in a nested cohort of the WHO Study on global AGEing and adult health (WHO-SAGE) Wave 2 (Aug-Dec 2015). 24-hour urine samples were collected in a random subsample (n = 1,299; of which n = 750 were considered valid (volume ≥ 300 mL and creatinine ≥ 4 mmol/day (women) or ≥ 6 mmol/day (men))). Follow-up urine samples were collected in Wave 3 (Jun 2018-Jun 2019), with replacements included for those lost to follow-up (n = 1,189; n = 548 valid). In those aged 18 - 49y, median salt intake was 7.8 (4.7, 12.0) g/day in W2 (n = 274), remaining similar in the W3 sample (7.7 (4.9, 11.3) g salt/day (n = 92); P = 0.569). In older adults (50 + y), median salt intake was 5.8 (4.0, 8.5) g/day (n = 467) in W2, and 6.0 (4.0, 8.6) g/day (n = 455) in W3 (P = 0.721). Controlling for differences in background characteristics, overall salt intake dropped by 1.15 g/day (P = 0.028). 24hr urinary Na concentrations from a countrywide South African sample suggest that salt intakes have dropped during the interim phase of mandatory sodium legislation. Further measurement of population level salt intake following stricter Na targets, enforced from June 2019, is necessary.

Association between the Urinary Sodium to Potassium Ratio and Blood Pressure in Adults: A Systematic Review and Meta-Analysis.

While sodium and potassium are individually important for blood pressure (BP) regulation, the relative contribution of sodium to potassium intake has not been sufficiently investigated. This study aimed to evaluate the association between urinary sodium to potassium ratio (UNa: K) and systolic and diastolic BP in adults. A systematic review (PROSPERO; CRD42016035296) was conducted and was reported according to PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. Three scientific databases (MEDLINE, Scopus, Web of Science) were searched to March 2020 while reference lists of included articles were further hand-searched. Randomized controlled trials (RCT), cohort and cross-sectional studies that assessed 24-h urinary excretion in adults were included. Data from eligible studies were extracted and summarized. Random effects meta-analysis was conducted on RCT data to assess standardized mean differences (SMD) in systolic and diastolic BP according to 24-h UNa: K. Thirty-nine studies were included. Meta-analysis of 5 RCTs found a lower UNa: K ratio to be associated with a significantly greater reduction in systolic and diastolic BP compared with a higher UNa: K ratio [SMD: -1.09 (95% CI: -1.91, -0.28) mmHg and -1.42 (95% CI: -2.24, -0.59) mmHg, respectively]. Heterogeneity between RCTs was observed in systolic and diastolic BP (I2 = 97%, P < 0.0001 and I2 = 98%, P < 0.0001, respectively). The current body of evidence demonstrates that a lower 24-h UNa: K ratio is associated with lower BP in adults. Dietary strategies to achieve an increase in potassium while at the same time lowering sodium would be beneficial in lowering BP.

Changes in Added Sugar Intake and Body Weight in a Cohort of Older Australians: A Secondary Analysis of the Blue Mountains Eye Study.

Background: The evidence regarding the association between added sugar (AS) intake and obesity remains inconsistent. The aim of this study was to investigate the association between changes in the percentage of energy intake from AS (EAS%) and changes in body weight in a cohort study of older Australians during 15 years of follow-up. In addition, associations were assessed according to whether EAS% intake was provided from beverage or non-beverage sources. Methods: Data were analyzed from the participants of the Blue Mountains Eye Study Cohort. Dietary data were collected at baseline (1992-94) and three five-yearly intervals using a 145-item food frequency questionnaire. Participants' body weight was measured at each time point. Five-yearly changes in EAS% intake and body weight were calculated (n = 1,713 at baseline). A generalized estimating equation (GEE) model was used to examine the relationship between the overall five-yearly changes in EAS% intake and body weight, adjusted for dietary and lifestyle variables. Results: In each time interval, the EAS% intake decreased by ~5% in the lowest quartile (Q1) and increased by ~5% in the highest quartile (Q4). The mean (SD) body weight change in Q1 and Q4 were 1.24 (8.10) kg and 1.57 (7.50) kg (first time interval), 0.08 (6.86) kg and -0.19 (5.63) kg (second time interval), and -1.22 (5.16) kg and -0.37 (5.47) kg (third time interval), respectively. In GEE analyses, the overall five-yearly change in EAS% intake was not significantly associated with body weight change (P trend = 0.837). Furthermore, no significant associations were observed between changes in EAS% intake from either beverage or non-beverage sources and changes in body weight (P trend for beverage sources = 0.621 and P trend for non-beverage sources = 0.626). Conclusion: The findings of this older Australian cohort do not support the association between changes in EAS% intake and body weight, regardless of AS food sources (beverage or non-beverage).

The views, experiences and expectations of Australian Meals on Wheels customers: A national survey.

OBJECTIVE: To investigate views and expectations of Australian Meals on Wheels (MOW) customers to inform the development of National Meal Guidelines and improve current services. METHODS: A survey was designed through literature review and consultations with key stakeholders. National convenience sampling returned  337 surveys. Descriptive statistics and chi-squared analyses were applied to the survey data. RESULTS: Meals on Wheels customers reported satisfaction with their current service, with the meal itself found to be the most valuable aspect. People living in small country towns were more likely to value the social contact provided by MOW than those in major cities (P = .001). Delivery of pantry items was the most popular additional option for future services. CONCLUSION: Valuable information for inclusion in the development of the National Meal Guidelines was provided: nutritional content of meals, meal variety, packaging and presentation, opportunities for nourishing snacks and pantry items, and social contact.

Determinants of change in blood pressure in Ghana: Longitudinal data from WHO-SAGE Waves 1-3.

The prevalence of hypertension is increasing in low- and middle-income countries, however statistics are generally derived from cross sectional surveys that utilize different methodologies and population samples. We investigated blood pressure (BP) changes over 11-12 years in a large cohort of adults aged 50 years and older (n = 820) included in the World Health Organization's Study on global AGEing and adult health (WHO-SAGE Ghana) Wave 1 (2007/8) with follow up in Wave 3 (2019). Participants' BP were measured in triplicate and a survey completed at both time points. Survey instruments collected information on sociodemographic characteristics, lifestyle, health behaviors and chronic conditions. While no significant difference was found in systolic BP between Waves 1 and 3, diastolic BP decreased by 9.7mmHg (mean = 88.6, 15.4 to 78.9, 13.6 respectively) and pulse pressure increased by 9.5mmHg (44.8, 13.7 to 54.3, 14.1). Awareness of hypertension increased by 37%, from (20% to 57%), but no differences were found for the proportion of hypertensives receiving treatment nor those that had controlled BP. Mixed effects modelling showed a decrease in diastolic BP was associated with increasing age, living in rural areas and having health insurance. Factors associated with an increased awareness of hypertension were residing in urban areas, having health insurance and increasing body mass index. While diagnosis of hypertension has improved over time in Ghana, there is an ongoing need to improve its treatment in older adults.

Salt and potassium intake among adult Ghanaians: WHO-SAGE Ghana Wave 3.

Though Ghana has high hypertension prevalence, the country lacks current national salt consumption data required to build and enhance advocacy for salt reduction. We explored the characteristics of a randomly selected sub sample that had valid urine collection, along with matched survey, anthropometric and BP data (n = 839, mean age = 60y), from the World Health Organization's Study on global AGEing and adult health (WHO-SAGE), Ghana Wave 3, n = 3053). We also investigated the relationship between salt intake and blood pressure (BP) among the cohort. BP was measured in triplicate and 24 h urine was collected for the determination of urinary sodium (Na), potassium (K), creatinine (Cr) and iodine levels. Hypertension prevalence was 44.3%. Median salt intake was 8.3 g/day, higher in women compared to men (8.6, interquartile range (IQR) 7.5 g/day vs 7.5, IQR 7.4 g/day, p <  0.01), younger participants (18-49 y) compared to older ones (50+ y) (9.7, IQR 7.9 g/day vs 8.1, IQR 7.1 g/day, p <  0.01) and those with higher Body Mass Index (BMI) (> 30 kg/m2) compared to a healthy BMI (18.5-24.9 kg/m2) (10.04, IQR 5.1 g/day vs 6.2, IQR 5.6 g/day, p <  0.01). More than three quarters (77%, n = 647) of participants had salt intakes above the WHO maximum recommendation of 5 g/d, and nearly two thirds (65%, n = 548) had daily K intakes below the recommended level of 90 mmol. Dietary sodium to potassium (Na: K) ratios above 2 mmol/mmol were positively associated with increasing BP with age. Population-based interventions to reduce salt intake and increase K consumption are needed.

Low anthocyanin plum nectar does not impact cognition, blood pressure and gut microbiota in healthy older adults: A randomized crossover trial.

Queen Garnet plum (QGP), known for its high levels of anthocyanins, is a hybrid of the Japanese plum developed in Queensland, Australia. Anthocyanins provide the red, blue, and purple pigments in plants with demonstrated beneficial health effects. This study hypothesized that low-dose anthocyanin QGP intake will have a significant positive effect on cognition, blood pressure, and gut microbiota in healthy older adults. A randomized crossover trial was conducted to determine the effect and within subject variance on cognition and 24 hr. ambulatory blood pressure in older adults without cognitive impairment following daily consumption of 200 mL low-dose anthocyanin (5 mg/100 g) QGP nectar (intervention) or raspberry cordial (control). Secondary outcomes included inflammatory markers (C-reactive protein), nerve growth factor (BDNF), and gut microbiota (16S rRNA gene sequencing). Twenty-eight participants (55+ years) were recruited. Each randomized treatment arm lasted for 8 weeks with a 4-week washout period. Cognition, blood pressure, and urine samples were measured at each visit (5 total) while blood and fecal samples were collected at baseline, 8 weeks, and 20 weeks. Repeated-measures ANOVA was used to analyze the data. Across the treatments, no significant difference was observed for the different domains of cognition, blood pressure, or anti-inflammatory biomarkers. No intervention effect was found for genera or class of gut microbes. Low anthocyanin nectar derived from the QGP did not have any significant effects on cognition, blood pressure, or gut microbiota in healthy older adults.

Nutrition information in pregnancy: Where do women seek advice and has this changed over time?

AIM: Nutrition during pregnancy is fundamental to both the health of the mother and her baby. Sources of nutrition-related information are available via many sources but their accuracy is unknown. The present study aimed to (a) identify where women source their nutrition information during pregnancy and (2) assess the accuracy of nutrition information for pregnancy that is available on the internet. METHODS: A survey instrument that identified the main sources of nutrition information was administered to 68 pregnant women recruited online. Data from this survey were compared to previous similar surveys conducted with pregnant mothers across years 2008, 2011 and 2014. A content analysis of websites was simultaneously conducted to assess the accuracy of available information. RESULTS: The main source of nutrition information for a variety of topics was verbal communication from health professionals (% responses affirmative for that source ranged from 6.6% to 69% across survey years). There was an increasing trend in internet sourced information for most nutrition topics, but this source remained low for iodine across all years (range: 7.3%-15.9%). The internet was the main source of information for listeria/food safety (15.3%-32.4%) and healthy eating (25%-42%). Of the n = 165 websites identified by the content analysis, 82.4% (n = 136) were rated as accurate, with government (96.9%) and business/company (100%) sites having the highest accuracy. CONCLUSION: Verbal communication from health professionals remains the most important source of nutrition information for pregnancy. The high credibility of websites indicates this to be an additional resource. Further study into health literacy levels among women visiting these sites is needed to assess impact on dietary behaviour.
