The Supplemental Nutrition Assistance Program (SNAP) Online Purchasing Pilot (OPP) authorised the use of SNAP benefits online in Maryland in May 2020. We assessed shopping behaviour and intentions associated with uptake and intended future use of online grocery shopping during and after COVID-19 among SNAP-eligible households.
Design:
In this mixed-methods study, participants completed a survey on online grocery shopping, and a purposefully sampled subset participated in focus groups or in-depth interviews between November 2020 and March 2021.
Setting:
Predominantly urban households in Maryland
Participants:
Primary shoppers of SNAP-eligible households with young children (n 310)
Results:
Most participants reported first shopping for groceries online after the OPP was implemented (57 %). Families who purchased groceries in-store less frequently were less likely to report ever buying groceries online (rate ratio (RR): 0·66, 95 % CI 0·46, 0·93) compared with weekly grocery shoppers. Shoppers who intended to purchase more groceries online in the next 6 months were more likely to have online shopping experience, although this differed by timing of online grocery service adoption. Participants reported more negative attitudes towards in-store grocery shopping during the pandemic than prior to its onset and cited COVID-19 as a motivator for ordering groceries online in focus groups. Most participants who had shopped online planned to continue after the pandemic (79 %).
Conclusions:
Most participants who shopped online started during the COVID-19 pandemic and considered the pandemic a key motivator. Findings suggest that low-income households will continue to shop online, affirming the need for policies that promote equitable access to healthy food online.
The public health nutrition workforce is well placed to contribute to bold climate action; however, tertiary educators are seeking practical examples of how to adequately prepare our future workforce. This study examines the responses of university students engaged in a co-designed planetary health education workshop as part of their public health nutrition training.
Design:
A mixed-methods approach was used to collect and interpret student responses to four interactive tasks facilitated during an in-person workshop. Data were analysed using statistical tests, frequency counting and content analysis.
Setting:
The intervention was co-designed by students (n 5) and an educator over a 4-week period as part of a larger multi-disciplinary study at an Australian university.
Participants:
The workshop engaged nutrition and dietetics students (n 44) enrolled in public health nutrition coursework.
Results:
Students reported an increase in self-perceived knowledge about planetary health as a concept and how they can promote it within their future professional roles. Students’ descriptions of what planetary health means to them were focused on humans’ role in protecting and preserving the ecosystem, the responsible and sustainable use of natural resources and a need to sustain a healthy life for future generations. Students prioritised the values of ‘collaboration’ and ‘respect’ as being critical to guide personal and professional practice to promote planetary health.
Conclusions:
This study demonstrated that incorporating planetary health curricula designed by, and for, university students could be a feasible and effective way to prepare the future public health nutrition workforce to address planetary health challenges.
This study assessed the association between baseline sociodemographic variables, body composition and 4-year changes in the intake of food groups, including sugar-sweetened beverages (SSB) among children, after the implementation of the health promotion levy.
Design:
Prospective cohort study.
Setting:
Ten schools in North West Province, South Africa.
Participants:
950 children aged 5–9 years at baseline and data of 672 children at follow-up. The frequency of intake from healthy and unhealthy food groups was assessed by questionnaire. Anthropometric and sociodemographic information were collected; BMI-for-age z-scores were calculated. The health promotion levy was implemented after baseline and follow-up measurements were done after 4 years. A random intercept generalised linear mixed model analysis was applied to investigate the time effect of the weekly intake of the foods adjusting for BMI-for-age z-scores and sociodemographic characteristics of the children.
Results:
The weekly frequency of intake from most food groups remained unchanged at follow-up. The frequency of SSB intake decreased significantly over 4 years. Decreased intake of SSB was not linked to increased intake of healthy foods. Changes in intakes from SSB were not associated with household income, parental education or BMI-for-age z-score categories. A decreased frequency of intake from SSB was observed following the implementation of the health promotion levy after baseline, in line with reports of national decreases in SSB sales in South Africa since 2017.
Conclusions:
The decreased frequency of SSB intakes following the implementation of the health promotion levy in South Africa may indicate that health policies can promote healthier dietary habits.
Early education and care (ECEC) is part of the everyday life of most children in developed economies, presenting exceptional opportunity to support nutrition and ongoing food preferences. Yet, the degree to which such opportunity is captured in policy-driven assessment and quality ratings of ECEC services is unknown.
Design:
Abductive thematic analysis was conducted, guided by key domains of knowledge in nutrition literature and examining identified themes within these domains.
Setting:
ECEC services (n 38) in Queensland, Australia.
Participants:
Data were a random sample of field notes pertaining to mealtimes and food provision (n 182) collected as evidence to inform quality ratings during assessment visits to ECEC services.
Results:
The field notes mapped to three theory-driven domains: provisions, practices and education. Reflecting policy specification, health, hygiene and safety were a key focus, but food quality and quantity were not. Assessors noted the promotion of child autonomy at mealtimes, yet little evidence pertaining to characteristics of educator-child interactions.
Conclusions:
Despite evidence that childhood nutrition is crucial for optimal development and learning, the quality and quantity of food are not directly assessed. Relationships and interactions at mealtimes provide an environment ideal for promoting learning and development, yet the policy guiding inspection and assessment of ECEC services directs focus to a more limited lens of safety, hygiene and promotion of ‘healthy foods’. Our findings identify a narrow conceptualisation of mealtimes focused on ‘health’ as limiting the potential to leverage mealtimes as places to support children’s nutrition and attendant development and learning.
To examine the proportion of products offered by leading food brands in Canada that are ‘unhealthy’ according to Health Canada’s (HC) nutrient profile model for proposed restrictions on food marketing to children (M2K-NPM).
Design:
Nutritional information for products offered by top brands was sourced from the University of Toronto FLIP and Menu-FLIP 2020 databases, respectively. HC’s M2K-NPM, which includes thresholds for Na, total sugars and saturated fat, was applied to products.
Setting:
Canada.
Participants:
Overall, 1385 products from top breakfast cereal (n 15 brands, n 222 products), beverage (n 21 brands, n 769 products) and yogurt (n 10 brands, n 394 products) brands, and 3153 menu items from seventeen chain restaurants in Canada were assessed (n 60 unique brands overall).
Results:
For 42 % of brands (n 21), 100 % of their products exceeded ≥1 nutrient threshold(s), with ≥50 % of the products offered by twenty-three brands (46 %) exceeding two thresholds. Specifically, one or more nutrient thresholds were exceeded by ≥50 % of the products offered by 14/15 breakfast cereal brands, 18/21 beverage brands, all ten yogurt brands and all seventeen restaurant brands. Notably, 100·0 % of the products offered by ten breakfast cereal, six beverage, two yogurt and three restaurant brands exceeded ≥1 threshold(s).
Conclusions:
Most products offered by top food brands in Canada exceeded HC’s M2K-NPM thresholds. Nonetheless, these brands could still be marketed under the proposed regulations, which exclude brand marketing (i.e. promotions without an identifiable product) despite its contribution to marketing power. These findings reinforce the need for Canada and other countries to include brand marketing in M2K policies.
To explore mothers’ and early childhood (EC) educators’ experiences of breast-feeding/breast milk provision and breast-feeding support in child care centres (CCC) in the USA.
Design:
We conducted one-time, semi-structured phone interviews with mothers and EC educators to examine perceptions of support, accommodations and barriers to breast-feeding in CCC. We administered a background survey to assess participant characteristics and quantify perceived degree of breast-feeding support in the workplace (mothers) and CCC (mothers and EC educators).
Setting:
US-based CCC
Participants:
Fifty working mothers using CCC for their infants and twenty-two EC educators
Results:
Interview themes and background surveys reflected neutral feelings towards breast-feeding support received (mothers) and provided (EC educators) in CCC. Maternal expectations for breast-feeding support in CCC were generally low; workplace and social support for breast-feeding were perceived as the most important factors impacting breast-feeding. EC educators’ capacity to offer breast-feeding support was constrained by CCC infant feeding regulations, inadequate breast-feeding training and time limitations. Tensions arose when mothers attempted to manage low milk supply at the CCC level by requesting EC educators to individualise feeding or milk storage practices for their infant.
Conclusions:
Breast-feeding efforts of working mothers are undermined in multiple settings, including the workplace and CCC. Improving breast-feeding outcomes for this population requires structural/policy changes that: (1) maximise opportunities for continued, direct breast-feeding and maternal/infant proximity and (2) enforce evidence-based CCC feeding protocols and standards and EC educator lactation training.
The Baby-Friendly Hospital Initiative (BFHI) designation is known to increase breast-feeding rates in the USA. However, less is known about barriers and facilitators to breast-feeding support practices in BFHI hospitals and how they differ from non-BFHI hospitals. We examined what barriers and facilitators are perceived to affect breast-feeding practices among BFHI and non-BFHI hospital administrators and further explored factors that presented challenges to the adoption and continuation of breast-feeding support practices.
Design:
Cross-sectional study was conducted. We measured whether hospitals were implementing 12 breast-feeding support practices and identified barriers and facilitators to the practices. The survey questionnaire included both structured and open-ended questions.
Setting:
This study included hospital administrators from both BFHI and non-BFHI hospitals from all regions of the USA to help elucidate potential differences.
Participants:
A stratified random sample of 50 % of BFHI and 50 % of non-BFHI hospitals was obtained. The final sample size included 113 BFHI and 177 non-BFHI hospital administrators.
Results:
Low interest among mothers was reported as the most significant barrier to providing breast-feeding support among all administrators. Non-BFHI hospital administrators were more likely to report cost, nursing staff and physician resistance and hospital infrastructure as barriers to initiating practices. In-person training was cited as the most important facilitator among both groups.
Conclusions:
Strengthening prenatal education for mothers and trainings for administrative and nursing staff and physicians is warranted in BFHI and non-BFHI hospitals. Staff management and hospital infrastructure need to be improved particularly in non-BFHI hospitals to provide adequate breast-feeding support for mothers.
Humanitarian aid, including food aid, has increasingly shifted towards the provision of cash assistance over in-kind benefits. This paper examines whether food security mediates the relationship between receipt of humanitarian cash transfers and subjective wellbeing among Syrian refugee youth in Jordan.
Design:
Secondary analysis of the 2020–21 Survey of Young People in Jordan, which is nationally representative of Syrian youth aged 16–30. We employ stepwise model building and structural equation models.
Setting:
Jordan.
Participants:
Syrian refugee youth aged 16–30 (n 1572).
Results:
While 92 % of Syrian households with youth received cash transfers from a UN agency, 78 % of households were food insecure using the Food Insecurity Experience Scale. Fifty-one percent of youth suffered from poor wellbeing using the WHO-5 subjective wellbeing scale. Household food insecurity was associated with poorer youth wellbeing. Receiving larger cash transfer amounts was associated with better wellbeing among Syrian youth in unadjusted models. The relationship between receipt of cash transfers and youth wellbeing was not mediated by food security.
Conclusion:
We do not find support for the hypothesis that food security is a mediator of the association between cash transfers and subjective wellbeing for this population.
Rheumatoid arthritis (RA) is characterised by chronic inflammation in joints. Obesity, stress, being women and dietary pattern are important in pathogenesis. The joint damage in RA is accelerated by oxidative stress. The aim of this study was to examine the serum total antioxidant level, nutritional status and Mediterranean diet adherence of adult women with RA. Thirty-five adult women RA patients and thirty-five healthy control participated in this study (45·4 ± 11·61 and 42·5 ± 8·50 years, respectively). Nutritional status, physical activity levels and adherence to the Mediterranean diet were questioned. Physicians assessed the disease activity score of patients with RA. Serum total antioxidant and oxidant status were analysed. The serum total antioxidant status of the control group was higher, whereas the oxidative stress index and total oxidant status were lower than that of the RA group. Dietary protein, fibre, EPA, retinol, Fe, Zn and total antioxidant intake in the RA group were lower than in the control group (P < 0·05). Individuals with higher fibre intake showed a significantly lower risk for RA after adjusting for potential confounding factors (OR = 0·845, 95 % CI = 0·773–0·923, P < 0·001). The mean physical activity level of the control group was higher than that of the RA group (1·59 ± 0·10 and 1·53 ± 0·13, respectively) (P = 0·01). In conclusion, serum antioxidant parameters and dietary antioxidant intake are decreased in patients with RA. Therefore, medical treatment for these patients should be supplemented with medical nutrition therapy to achieve optimal nutritional status.
Colorectal cancer (CRC), the third most common cancer globally, causes over 900 000 deaths annually. Although vitamin D is observed to have potential anti-carcinogenic properties, research findings on its preventable effect against CRC remain inconclusive. Notably, different subsites within the colon and rectum may be associated with distinct risk factors. While some studies have explored this relationship with circulating 25-hydroxyvitamin D (25(OH)D), the results remain contradictory. Our study employed a nested case–control design, involving 775 CRC cases matched with 775 cancer-free controls based on age, region of living and the time of blood sampling. The study was conducted within the Norwegian Women and Cancer post-genome cohort, which comprises approximately 50 000 women. We measured pre-diagnostic circulating plasma 25(OH)D status 5–13 years before diagnosis. Adjustment variables were based on self-administered questionnaires and included BMI, physical activity level, smoking, intake of processed meat, calcium, alcohol and fibre. An increase of 5 nmol/l in 25(OH)D reduced the risk of proximal colon cancer by 6 % (OR = 0·94, 95 % CI 0·89, 0·99). Furthermore, a sensitivity analysis revealed a 62 % increased risk among the women with 25(OH)D levels below 50 nmol/l compared with sufficient levels, ≥ 50 to < 75 nmol/l (OR = 1·62, 95 % CI 1·01, 2·61). No association was found with CRC, colon or distal colon cancer. We observed a subsite-specific association between 25(OH)D and CRC, highlighting the need for further investigation to elucidate the potential underlying mechanisms and clinical implications.
Oxidative stress is present in chronic obstructive pulmonary disease (COPD); however, the effect of increased dietary antioxidants on reducing COPD risk remains unclear. The aim of this study was to investigate the association of the composite dietary antioxidant index (CDAI) with COPD in adults. This study conducted a cross-sectional investigation using data from the National Health and Nutrition Examination Survey (NHANES) spanning from 2015 to March 2020 to explore the association between CDAI and COPD in adults. This study included 9295 participants. Three logistic regression models (crude model, partially adjusted model and fully adjusted model) and restricted cubic spline (RCS) curves were utilised to assess the association between CDAI levels and COPD risk. Subsequently, a two-sample Mendelian randomisation (MR) was employed to analyse the causal impact of antioxidant levels within CDAI on the occurrence of COPD. CDAI levels were inversely associated with COPD after adjusting for confounders (OR = 0·97, 95 % CI 0·95, 1·00), and the association was linear (P < 0·001), and the results of the RCS showed that CDAI was linearly correlated with COPD occurrence (P < 0·001). MR analysis revealed a causal relationship between vitamin C and COPD occurrence (OR = 0·99, 95 % CI 0·98, 1·00, P < 0·05). Our study indicates that dietary sources of antioxidants may reduce the risk of COPD occurrence, and the results of the MR analysis further show that vitamin C is causally associated with a reduced risk of COPD occurrence. However, further exploration is needed to understand how antioxidants prevent COPD.
The creation of a healthy food environment is highly dependent on the policies that governments choose to implement. The objective of this study is to compare the level of implementation of current public policies aimed at creating healthy food environments in Burkina Faso with international good practice indicators.
Design:
This evaluation was carried out using the Food-EPI tool. The tool has two components (policy and infrastructure support), thirteen domains and fifty-six good practice indicators adapted to the Burkina Faso context.
Setting:
Burkina Faso.
Participants:
Expert evaluators divided into two groups: the group of independent experts from universities, NGO and civil society and the group of experts from various government sectors.
Results:
Among the fifty-six indicators, it was assessed the level of implementation as ‘high’ for six indicators, ‘medium’ for twenty-four indicators, ‘low’ for twenty-two indicators and ‘very low’ for four indicators. High implementation level indicators include strong and visible political support, targets on exclusive breastfeeding and complementary feeding, strong and visible political support for actions to combat all forms of malnutrition, monitoring of exclusive breastfeeding and complementary feeding indicators, monitoring of promotion and growth surveillance programmes and coordination mechanism (national, state and local government). The indicators on menu labelling, reducing taxes on healthy foods, increasing taxes on unhealthy foods and dietary guidelines are the indicators with a ‘very low’ level of implementation in Burkina Faso.
Conclusions:
The general results showed that there is a clear need for further improvements in policy and infrastructure support to promote healthy food environments.
Indigenous peoples are often not routinely included in iodine programmes because of language barriers and remote access and may thus be at higher risk of iodine deficiency disorders, which could adversely impact their quality of life. We conducted this cross-sectional study in the remote Pwo Karen community of Thailand to determine the urinary iodine concentration of school-aged children and women of reproductive age and investigate the iodine content in household salt. We measured urinary iodine concentration in spot urine samples from healthy school-aged children and women of reproductive age, administered a questionnaire, estimated daily iodine intake and collected household salt samples to determine salt iodine concentration. The median urinary iodine concentration (range) of school-aged children (n 170) was 192 (136–263) µg/l, which was significantly higher than women of reproductive age (n 306) (147 (89–233) µg/l) (P < 0·001). The estimated daily iodine intake in school-aged children and women of reproductive age were 135 and 195 μg/d, respectively. The median (range) iodine concentration in rock and granulated salts consumed in the households were 2·32 (0·52–3·19) and 26·64 (20·86–31·01) ppm, respectively. Surprisingly, the use of iodised salt and the frequency of seafood consumption were NS predictors of urinary iodine concentration in these two groups. Our data suggest that school children and women of the Pwo Karen community have sufficient iodine intake, indicating the Thai salt iodisation programme is effectively reaching even this isolated Indigenous community. Sentinel surveys of remote vulnerable populations can be a useful tool in national iodine programmes to ensure that programme coverage is truly universal.
Lifestyle and diet may affect the reproductive cycle. A dietary index called Diet Diversity Score (DDS) may be related to various reproductive outcomes. The present review aims to look over and conclude the prior studies on the relationship between the diversity of food ingredients and issues related to reproductive health and pregnancy. In the case of this relationship, our findings can increase clinical knowledge and help recommend a well-balanced diet for the target group. A comprehensive search was performed in major databases such as PubMed, Google Scholar, Web of Science, Scopus, and Scientific Information Database until March 2024. This research was combined with a search of Elsevier and SpringerLink databases, which led to the inclusion of relevant articles in this review. Our study was conducted based on 27 articles from 2012 to 2023, all containing a possible link between dietary diversity and reproductive complications. The Newcastle-Ottawa Scale quality assessment was used to evaluate the quality of included studies. Due to our results, a higher score in DDS, which led to an increased intake of major nutrients and a greater variety of foods, was correlated with a lower risk of reproductive health disorders such as polycystic ovary syndrome, maternal anaemia, and maternal bone status, as well as a reduced likelihood of certain birth outcomes, including low-birth weight infants, Apgar score and congenital heart defect. These findings highlight the importance of improving the DDS for maternal and infant health.
Low iron (Fe) stores at birth may adversely influence child cognitive and motor development. The aims of this study were to assess cord blood Fe levels and explore maternal and neonatal factors associated with Fe status. Cord blood specimens (n 46) were obtained from the BC Children’s Hospital BioBank in Vancouver, Canada. The primary outcome was cord plasma ferritin, measured using sandwich-ELISA. Predictors of interest included maternal age, gestational age, gravidity, infant sex, birth weight and delivery method. Median (interquartile range (IQR)) maternal age and gestational age at delivery was 33·5 (29·3–35·8) years and 36·5 (30·0–39·0) weeks, respectively, and 44 % of infants were female. Median (IQR) cord ferritin was 100·4 (75·7–128·9) µg/l, and 26 % had low Fe status (ferritin <76 µg/l). Among preterm deliveries, a 1-week increase in gestational age was associated with a 6·22 (95 % CI (1·10, 9·52)) µg/l increase in median cord ferritin. However, among term deliveries, a negative trend was observed (–2·38 µg/l per week of gestation (95 % CI (–34·8, 0·78))), indicating a potential non-linear relationship between gestational age and cord ferritin. Female term infants had higher cord ferritin compared with males (β (95 % CI): 30·3 (18·4, 57·9) µg/l), suggesting sex-specific differences in Fe transfer, acquisition and utilisation. Cord ferritin was higher with vaginal deliveries compared with caesarean sections (β (95 % CI): 39·1 (29·0, 51·5) µg/l). Low Fe status may be a concern among infants in Canada; however, further research is needed to inform appropriate thresholds to define optimal Fe status in cord blood.
Interest in studies examining the effect of temperament types on nutrition has recently increased. The aim of this study was to evaluate the relationship between nine types of temperament, anthropometric measurements, and nutrition in adults. This study was conducted on 1317 individuals aged between 18 and 55 years. Descriptive information, dietary habits and anthropometric measurements of the participants were questioned. The Nine Types of Temperament Scale was administered to the individuals and food consumption records were obtained with a 24-hour retrospective reminder method. Type 2 scores of obese participants were higher than those of underweight and normal body weight; Type 8 scores of overweight participants were higher than those of normal body weight. Daily dietary intake of protein, riboflavin, folate, vitamins K, C, calcium, iron, and cholesterol were negatively associated with Type 1 score; protein, magnesium, iron, zinc intake, and water consumption were negatively associated with Type 2 score. Type 3 score was negatively associated with dietary CHO (%), dietary magnesium, iron, and zinc intake and positively associated with water consumption. The results of the study indicate significant relationships between temperament types, dietary habits, and anthropometric measures. In this context, considering temperament types when planning dietary patterns of individuals may be a new approach.
The adoption of policies promoting healthier restaurant food environments is contingent on their acceptability. Limited evidence exists regarding individual characteristics associated with restaurant food environment policy acceptability, especially health-related characteristics. This study examined associations between health characteristics and restaurant food environment policy acceptability among urban Canadians.
Design:
Links between health characteristics and complete agreement levels with selected policies were examined using data in the cross-sectional Targeting Healthy Eating and Physical Activity survey study, that is, a large pan-Canadian study on policy acceptability. For each policy, several logistic multilevel regression analyses were conducted.
Setting:
Canada’s seventeen most populated census metropolitan areas.
Participants:
Urban Canadian adults responded to the survey (n 27 162).
Results:
Body mass index was not associated with acceptability after adjustments for other health and sociodemographic characteristics were made. Across all policies and analyses, those reporting excellent or very good health statuses were more likely to be in complete agreement with targeted policies than those with good health statuses. For selected policies and analyses, those reporting poor health statuses were also more likely to be in complete agreement than those describing their health status as good. For all policies and analyses, both those consuming restaurant-prepared foods daily and those never consuming these foods were more likely to be in complete agreement than those consuming these foods once per week.
Conclusions:
More research is needed to explain discrepancies in acceptability according to health characteristics. Bringing this study’s findings to the attention of policymakers may help build momentum for policy enactment.
