The Less Salt, More Life program was the first voluntary salt reduction initiative in Argentina. This article analyzes the perspectives of the stakeholders involved in this voluntary agreement between the Ministry of Health and the food industry to gradually reduce sodium content in processed foods. This exploratory case study used a qualitative approach including 29 in-depth interviews with stakeholders from the public and private sectors and identified the role of the different stakeholders and their perceptions regarding the challenges encountered in the policy process that contribute to the debate on public-private partnerships in health policies. The article also discusses the initiative’s main challenges and controversies.

The objective of this study is to analyze how food advertising is perceived by mothers from different socioeconomic sectors of the Metropolitan Area of Buenos Aires, Argentina. Between May and November 2015, eight focus groups were conducted with the participation of 49 mothers of different education levels living in the study area. The results show how the purchasing decisions of mothers are influenced by the requests of their children, which are in turn prompted by food advertising and promotion. The study also shows how food advertising and promotion are combined with other environmental factors (greater supply of food products, "more demanding" children) that affect the decision-making process of mothers regarding their children's nutrition and foster the consumption of certain unhealthy products. This situation was observed in all the focus groups, without differences among education levels.

Background Pervasive marketing of unhealthy foods is one of the main drivers behind the global epidemic of childhood and adolescent overweight and obesity. Sex and gender differences come into play in the design of and responses to these marketing strategies, contributing to the perpetuation of stereotyped behavior and generating disparities in food choices and health among boys and girls. The purpose of this paper is to review the current the literature regarding gender differences in food marketing design and perception among children and adolescents to facilitate evidence-based policy dialogues to address gender-based health disparities in NCD prevention.Methods Scoping review of articles published in scientific journals in English and Spanish from 2003 on that addressed the influence of food marketing on eating behaviors among children and adolescents including a gender perspective. The methodological quality of each article was assessed following criteria specific to each study design.Results A total of 40 articles (42 studies) were included in the review. 19 were experimental and 23 had descriptive, cross-sectional designs. 22 studies were found to have low methodological quality, while 11 and 9 were of medium and high quality, respectively. 24 studies found gender-based differences with regards to the effect of food marketing on food intake, food choice and preferences, responses to specific marketing strategies and techniques, perceptions and attitudes towards food marketing and the need for its regulation, and advertising content and exposure. Conclusions The evidence suggests that food marketing has a similar impact on the consumption of unhealthy foods on both boys and girls, but boys were found to be exposed to food advertising more intensively and their preferences to be more affected by this exposure, in line with a mostly male-dominant advertising content. Limitations of these studies include taking gender as an unproblematic construct equivalent to biological sex and the lack of studies focused on developing countries. As gender is a cross-sectional dimension that interacts with other factors driving health disparities, an integrated gender perspective is needed in order to develop effective, evidence-based policies to control food marketing and tackle the childhood overweight pandemic.

In 2015, the Pan American Health Organization (PAHO) published sodium targets for packaged foods, which included two distinct levels: one “regional” and one “lower” target. Changes to the sodium content of the food supply in Latin American Countries (LAC) has not been evaluated. A repeated cross-sectional study used food label data from 2015 (n = 3859) and 2018 (n = 5312) to determine changes in the proportion of packaged foods meeting the PAHO sodium targets and the distribution in the sodium content of foods in four LAC (Argentina, Costa Rica, Paraguay, Peru). Foods were classified into the 18 food categories in the PAHO targets. The proportion of foods meeting the regional targets increased from 82.9% to 89.3% between 2015 and 2018 (p < 0.001). Overall, 44.4% of categories had significant decreases in mean sodium content. Categories with a higher proportion of foods meeting the regional and lower targets in 2018 compared to 2015 (p < 0.05) were breaded meat and poultry, wet and dry soups, snacks, cakes, bread products, flavored cookies and crackers, and dry pasta and noodles. While positive progress has been made in reducing the sodium content of foods in LAC, sodium intakes in the region remain high. More stringent targets are required to support sodium reduction in LAC.
