Impact of Digital Advertising Policy on Harmful Product Promotion: Natural Language Processing Analysis of Skin-Lightening Ads.

Introduction: Starting June 30, 2022, Google implemented its revised Inappropriate Content Advertising Policy, targeting discriminatory skin-lightening ads that suggest superiority of certain skin shades. This study evaluates the ad content changes from 2 weeks before to 2 weeks after the policy's enforcement.

Methods: Text ads from Google searches in eight countries (Bahamas, Germany, India, Malaysia, Mexico, South Africa, United Arab Emirates, and United States) were collected in 2022, totaling 1,974 prepolicy and 3,262 post-policy ads, and analyzed in 2023.

Associations between weight discrimination and the use of potentially harmful dietary supplements during the COVID-19 pandemic in the United States.

The dietary supplements industry disproportionately markets potentially harmful products promising weight loss, cleansing/detoxing, and boosted energy and immunity to women. The COVID-19 pandemic heightened consumer concerns around health and body weight, which may have increased women's risks of using supplements, particularly if they had a higher weight and experienced weight discrimination. This study aimed to estimate inequities in prevalence and change in use of weight-loss, cleanse/detox, immunity, and energy supplements in the first year of the pandemic and to assess the extent to which the relationship between weight and supplement use differs across discrimination experiences.

Financial precarity, food insecurity, and psychological distress prospectively linked with use of potentially dangerous dietary supplements during the pandemic in the US.

Introduction: Supplements sold with claims to promote weight loss, cleansing/detoxing, increased energy, or boosted immunity can be dangerous, and consumers experiencing extreme stressors may be especially vulnerable to deceptive claims. The purpose of our study was to investigate associations of financial strain and psychological distress during the COVID-19 pandemic with use of supplements sold for weight loss, cleanse/detox, energy, or immunity.

Methods: We used repeated-measures data gathered over five survey waves from April/May 2020-April 2021 from the COVID-19 Substudy ( = 54,951), within three prospective US national cohorts (Nurses' Health Study 2, Nurses' Health Study 3, and Growing Up Today Study), to investigate longitudinal associations between financial strain and psychological distress and risk of use of potentially dangerous types of supplements.
