Children's exposure to unhealthy food advertising on Philippine television: content analysis of marketing strategies and temporal patterns.

Background: This study conducted an exploratory content analysis of TV food advertisements on the top three most popular channels for Filipino children aged two to 17 during school and non-school days.

Methods: Data were collected by manually recording of aired advertisements from 16 non-school days (July to September 2020) and 16 school days (January to April 2021). Descriptive and inferential statistical analyses were used to assess children's rates of exposure to food advertisements (mean ± SD of advertisements aired per channel per hour), the healthiness of promoted foods (as permitted (healthier) or not permitted (unhealthy) according to nutrient profiling models from the World Health Organization), and persuasive techniques used in food advertisements, including promotional characters and premium offers.
