Policies to restrict unhealthy food and beverage price promotions have been recommended, as part of a broader strategy to reduce obesity, but little evidence underpins such recommendations. We aimed to synthesize the literature on the prevalence of healthy and unhealthy food and beverage price promotions and their potential influence on purchasing behaviour. Eight scientific databases (covering health, business, and marketing) and grey literature were systematically searched using search terms related to "food and beverage price promotions" up until July 2019. Articles were included if they examined prevalence of, and/or consumer response to, food and non-alcoholic beverage price promotions, from a nutritional perspective. Of the 16 included studies, eight examined the prevalence of price promotions and eight examined the potential influence of price promotions on purchasing behaviour. Seven of the "prevalence" studies found that price promotions were more common for unhealthy foods and beverages. Seven "influence" studies found a greater proportion of price-promoted purchases were for unhealthy compared with healthy products. Policies that reduce the prevalence and/or influence of price promotions on unhealthy foods and beverages may shift consumer purchasing away from unhealthy foods and beverages. Empirical studies are required to better understand how consumers and industry may respond to such policies.
Summary Children's exposure to advertising of unhealthy food and nonalcoholic beverages that are high in saturated fats, salt and/or sugar is extensive and increases children's preferences for, and intake of, targeted products. This systematic review examines the differential potential exposure and impact of unhealthy food advertising to children according to socio‐economic position (SEP) and/or ethnicity. Nine databases (health, business, marketing) and grey literature were searched in November 2019 using terms relating to ‘food or drink’, ‘advertising’ and ‘socioeconomic position or ethnicity’. Studies published since 2007 were included. Article screening and data extraction were conducted by two independent reviewers. Quality of studies was assessed using the Newcastle‐Ottawa quality scale. Of the 25 articles included, 14 focused on exposure to unhealthy food advertising via television, nine via outdoor mediums and two via multiple mediums. Most studies (n = 19) revealed a higher potential exposure or a greater potential impact of unhealthy food advertising among ethnic minority or lower SEP children. Few studies reported no difference (n = 3) or mixed findings (n = 3). Children from minority and socio‐economically disadvantaged backgrounds are disproportionately exposed to unhealthy food advertising. Regulations to restrict unhealthy food advertising to children should be implemented to improve children's diets and reduce inequities in dietary intake.
Objectives. To examine the prevalence and magnitude of price promotions in a major Australian supermarket and how they differ between core (healthy) and discretionary (less healthy) food categories. Methods. Weekly online price data (regular retail price, discount price, and promotion type) on 1579 foods were collected for 1 year (April 2017 to April 2018) from the largest Australian supermarket chain. Products audited were classified according to Australian Dietary Guidelines definitions of core and discretionary foods and according to their Health Star Rating (a government-endorsed nutrient profiling scheme). Results. On average, 15.1% (95% confidence interval [CI] = 14.7%, 15.3%) of core foods and 28.8% (95% CI = 28.6%, 29.0%) of discretionary foods were price promoted during a given week. Average discounts were −15.4% (95% CI = −16.4, −14.4) for core products and −25.9% (95% CI = −26.8, −25.1) for discretionary products. The percentage of products on price promotion and the size of the discount were larger for products with a lower Health Star Rating (P < .05). Conclusions. Price promotions were more prevalent and greater in magnitude for discretionary foods than for core foods. Policies to reduce the prevalence and magnitude of price promotions on discretionary foods could improve the healthiness of food purchased from supermarkets.
Objective: To compare the cost and affordability of two fortnightly diets (representing the national guidelines and current consumption) across areas containing Australia’s major supermarkets. Design: The Healthy Diets Australian Standardised Affordability and Pricing protocol was used. Setting: Price data were collected online and via phone calls in 51 urban and inner regional locations across Australia. Participants: N/A. Results: Healthy diets were consistently less expensive than current (unhealthy) diets. Nonetheless, healthy diets would cost 25-26% of the disposable income for low-income households and 30-31% of the poverty line. Differences in gross incomes (the most available income metric which overrepresents disposable income) drove national variations in diet affordability (from 14% of the median gross household incomes in the Australian Capital Territory and Northern Territory, to 25% of the median gross household income in Tasmania). Conclusions: In Australian cities and regional areas with major supermarkets, access to affordable diets remain problematic for families receiving low incomes. These findings are likely to be exacerbated in outer regional and remote areas (not included in this study). To make healthy diets economically appealing, policies that reduce the (absolute and relative) costs of healthy diets and increase the incomes of Australians living in poverty are required.
A case is presented of a 56 year old man with a history of idiopathic pancreatitis and multiple admissions for Klebsiella sepsis from an intra‐abdominal focus, who in February 1980, developed spontaneous jejunal perforations on two occasions due to multiple ulcers in the small intestine associated with multiple hepatic metastases from a gastrin‐secreting islet‐cell tumor (gastrinoma) of the pancreas. On searching the literature, no other record could be found of an association between pancreatitis and a gastrinoma, although in this patient the two disease processes appear to be inextricably related.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
