To examine children’s exposure to food and beverage advertising across a year of Colombian television based on whether products exceed Pan-American Health Organization (PAHO)-defined nutrient thresholds.

Nutritional information was obtained for all foods and beverages advertised and used to categorise each product according to the product category (e.g. beverage, snack food) and nutritional quality based on the PAHO model for identifying products in excess of free sugars, Na or saturated fat or containing non-caloric sweeteners or trans-fat. Television audience ratings data were used to derive the average child audience (unique child viewers) per ad and the number of times ads were seen by children in a single week (weekly impressions) based on product category and nutritional quality.

All food and beverage ads on cable and over-the-air TV in Colombia in 2017.

N/A.

Of all instances of TV ads, 89·3 % were of unhealthy products. A larger proportion of male and female children, as well as children from low (88·01 %), mid (89·10 %) and high (89·10 %) socio-economic status, are exposed to advertising of unhealthy products, but no significant difference was found between these proportions.

The majority of foods and beverages advertised to Colombian children are unhealthy. These findings highlight a need to implement statutory measures to reduce children’s exposure to unhealthy food advertising in Colombia, as obesity and overweight have been increasing among school-age children in Colombia, and exposure to television advertising of unhealthy foods is a known contributor to children’s food intake and obesity.

This study aims to analyse the differences, with regard to socio-cultural characteristics and dietary habits, between low and high consumers of yoghurt and other fermented dairy product desserts, and the nutritional significance of these differences.

We analysed the diet of a healthy population (4–65 years), using the 24-hour recall method, on three non-consecutive days. The participants were grouped by age and sex and were also divided into tertiles on the basis of yoghurt consumption. We compared energy and nutrient intakes, educational level and socio-economic status in the low consumption (LC) group and the high consumption (HC) group.

In general there were no significant differences in energy intake or nutritional profile between LC and HC groups. The only significant difference was in the percentage of energy provided by lipids, which was significantly lower in HC women, possibly due to the high number of women in this group who consumed low-fat yoghurt. There were significant differences in the distribution of HC and LC subjects according to the three educational levels (P < 0.05) but n according to socio-economic status.

The fact of being a high consumer of fermented dairy products took place in the framework of other dietary changes that compensated for this high consumption, resulting in the absence of significant differences in energy intake and nutritional profile between HC and LC subjects. The only exception was found in women who consumed low-fat dairy products. There was a relationship between high consumption of fermented dairy products and educational level.
