RESUMO

The high cost of healthy foods makes maintaining a healthy dietary pattern challenging, particularly among people with diabetes who are experiencing food insecurity. The objectives of this study were to: 1) review evidence on the impact of providing material benefits (e.g., food coupons/vouchers, free food, or financial subsidies/incentives) to improve access to food on clinical parameters, dietary intake, and household food insecurity in people with diabetes, and 2) review relevant economic evidence. Six databases were searched from inception to March 2023 for longitudinal studies with quantitative outcomes. Twenty-one studies were included in the primary review and 2 in the economic analysis. Risk of bias was high in 20 studies and moderate in 1 study. The number of randomized controlled trials and nonrandomized studies reporting statistically significant improvement, alongside Grading of Recommendations Assessment, Development, and Evaluation (GRADE) certainty of the evidence was: HbA1c: 1/6 and 4/12 (very low), systolic blood pressure: 0/3 and 1/8 (very low), diastolic blood pressure: 0/3 and 1/7 (very low), BMI: 0/5 and 2/8 (very low), body weight: 0/0 and 1/3 (very low), hypoglycemia: 1/2 and 1/2 (very low), daily intake of fruits and vegetables: 1/1 and 1/3 (very low), daily intake of whole grains: 0/0 and 0/2 (very low), overall diet quality: 2/2 and 1/1 (low), and household food insecurity: 2/3 and 0/0 (very low). The 2 studies included in the economic analysis showed no difference in Medicare spending from Supplemental Nutrition Assistance Program participation and cost-savings from medically tailored meals in an economic simulation. Overall, providing material benefits to improve access to food for people with diabetes may improve household food insecurity, fruit and vegetable intake, and overall diet quality, but effects on clinical parameters and whole grain intake are unclear. The certainty of evidence was very low to low by GRADE. PROSPERO (CRD42021212951).

RESUMO

Unhealthy food and beverage availability and sponsorship undermine healthy food practices in sport and recreation. We conducted a focused ethnography with reflexive photo-interviewing to examine parents' awareness, reactions, and experiences of food and beverage marketing in and around their children's physical activity in public sport and recreation facilities. Eleven parents took photos of what they thought their facility was 'saying about food and eating'. Photos guided semi-structured interviews on the '4Ps' of marketing (product, pricing, placement, promotion). Thematic analysis was conducted by holistic coding followed by in vivo, versus, and value coding. Photo-taking increased parents' awareness of food marketing in facilities. Reactions to food and beverage marketing were positive or negative depending on parents' perspectives of healthy food availability (choice), marketers' motives, and mixed messages within the facility. Parents experienced their children requesting 'junk' food at the facility leading to parents actively attempting to reduce the frequency of these requests. Healthy eating promotion in sport and recreation facilities was misaligned with the foods and beverages available which contributed to parents' distrust of social marketing initiatives. Critically evaluating the alignment of commercial and social marketing in recreation and sport may help inform effective healthy eating interventions that are accepted and supported by parents.

RESUMO

Many recreation and sports facilities have unhealthy food environments, however managers are reluctant to offer healthier foods because they perceive patrons will not purchase them. Preliminary evidence indicates that traffic light labeling (TLL) can increase purchase of healthy foods in away-from-home food retail settings. We examined the effectiveness of TLL of menus in promoting healthier food purchases by patrons of a recreation and sport facility concession, and among various sub-groups. TLL of all menu items was implemented for a 1-week period and sales were assessed for 1-week pre- and 1-week post-implementation of TLL (n = 2101 transactions). A subset of consumers completed a survey during the baseline (n = 322) and intervention (n = 313) periods. We assessed change in the proportion of patrons' purchases that were labeled with green, yellow and red lights from baseline to the TLL intervention, and association with demographic characteristics and other survey responses. Change in overall revenues was also assessed. There was an overall increase in sales of green (52.2% to 55.5%; p < 0.05) and a reduction in sales of red (30.4% to 27.2%; p < 0.05) light items from baseline to the TLL period. The effectiveness of TLL did not differ according to any of the demographic or other factors examined in the survey. Average daily revenues did not differ between the baseline and TLL periods. TLL of menus increased purchase of healthy, and reduced purchase of unhealthy foods in a publicly funded recreation and sport facility, with no loss of revenue. Policymakers should consider extending menu labeling laws to public buildings such as recreation and sports facilities to promote selection of healthier items.

RESUMO

Maternal nutrient intake in the prenatal period is an important determinant of fetal growth and development and supports maternal health. Many women, however, fail to meet their prenatal nutrient requirements through diet alone and are therefore advised to consume nutrient supplements. The purpose of this study was to describe the use of natural health products (NHP) by pregnant women in each trimester of pregnancy. Women (n = 599) participating in the first cohort of the Alberta Pregnancy Outcomes and Nutrition (APrON) study completed an interviewer-administered supplement intake questionnaire during each trimester of pregnancy. NHP use was high, with >90% taking multivitamin/mineral supplements, and nearly half taking at least one additional single-nutrient supplement. Compliance with supplementation guidelines was high for folic acid (>90%), vitamin D (∼70%) and calcium (∼80%), but low for iron (<30%) and for all four nutrients together (≤11%). On average, women met or exceeded the recommended dietary allowance for folic acid, vitamin D and iron from NHPs alone, with median daily intakes of 1000 µg, 400 IU and 27 mg, respectively. The median calcium intake was 250 mg d(-1) . Up to 26% of women exceeded the tolerable upper intake level for folic acid and up to 19% did so for iron at some point of their pregnancy. Findings highlight the need to consider both dietary and supplemental sources of micronutrients when assessing the nutrient intakes of pregnant women.

RESUMO

BACKGROUND & AIMS: This study assessed the effects of administering a lipid emulsion containing eicosapentaenoic and docosahexaenoic acid before and after open-heart surgery on cytokine production and length of hospital stay in infants. METHODS: Thirty-two infants (40 ± 2.3 weeks gestational age; 10.6 days at time of surgery) undergoing open-heart surgery with cardiopulmonary bypass were randomized to receive an intravenous lipid emulsion with (treatment) or without (control) eicosapentaenoic and docosahexaenoic acid in this prospective, randomized, double-blind, controlled trial. RESULTS: Mean plasma TNF-α concentration was significantly (p = 0.003) lower in the treatment (5.9 pg/mL) compared to the control group (14.8 pg/mL). In infants without sepsis, plasma TNF-α did not differ according to treatment, however when sepsis developed, mean plasma TNF-α was 21.1 pg/mL and 1.5 pg/mL (p = 0.0007) in control and treatment groups, respectively. Plasma TNF-α was positively correlated with length of hospital stay in the control group (p = 0.01), and negatively correlated with length of stay in the treatment group (p = 0.004), with a significant time by treatment interaction (p = 0.02). CONCLUSIONS: Providing a lipid emulsion containing eicosapentaenoic and docosahexaenoic acid reduces TNF-α concentrations in infants undergoing open-heart surgery. Lipid emulsions containing eicosapentaenoic and docosahexaenoic acid may ameliorate the inflammatory response among critically ill infants.

RESUMO

Although obesity was rarely observed among children 30 years ago, it is now evident among Canadian children of all ages. Currently, 15.2% of 2- to 5-year-old children are overweight, whereas 6.3% are obese. Limited data suggest that poor dietary and physical activity patterns are increasing obesity risk among these young children. Body weight and lifestyle behaviours are known to track from childhood to adulthood, thereby increasing the risk for obesity and other chronic diseases later in life. Intrauterine life, infancy, and the preschool years may all include critical periods that program the long-term regulation of energy balance, and therefore obesity-prevention strategies should be initiated in utero and continue throughout childhood and adolescence. Although single-strategy obesity-prevention initiatives have had limited success, programs that target multiple behaviours may help reduce body weight and body fat among young children. Parental involvement is key to the success of obesity-prevention programs at a young age, as parents have primary control over their children's food and activity environments. Accordingly, parental obesity is the best predictor of childhood obesity. Parents should be encouraged to teach and role model healthy lifestyle behaviours for their young children. Health professionals can also be involved in obesity prevention, as they are ideally placed to identify young children at risk for obesity. By calculating and plotting the body mass index for all children, and initiating obesity-prevention strategies in utero, health professionals can help curb the rise in overweight and obesity among young children.
