Medicaid expansion and non-alcoholic beverage choices by low-income households

This article investigates the impact of the 2010 Patient Protection and Affordable Care Act (ACA) on the healthfulness of non-alcoholic beverage (NAB) choices of low-income households. A theoretical analysis proposes an income effect that increases unhealthy beverage purchases after Medicaid expansion and a nutrition education effect that decreases them. To empirically test these effects, we utilize household-level data for NAB purchases in 52 U.S. metropolitan areas. Our identification strategy is based on eligible households following the 2012 Supreme Court ruling that allowed states to opt out of Medicaid expansion. We examine changes in purchases across NAB categories and in purchases at the product-brand level. Empirical results indicate that Medicaid expansion resulted in eligible households buying more diet carbonated soft drinks (CSDs) and bottled water, with no effect on regular CSDs, fruit juice, fruit drinks, milk, or tea. Moreover, the expansion led to decreases in sugar purchases and increases in purchases of NAB products with lower sugar content, highlighting the benefits of supplementing the medical benefits of Medicaid with diet quality programs, such as nutrition education.

Global Patterns of Adolescent Fruit, Vegetable, Carbonated Soft Drink, and Fast-Food Consumption: A Meta-Analysis of Global School-Based Student Health Surveys

BACKGROUND

Adolescence presents an opportunity to influence diet, which impacts present and future health outcomes, yet adolescent diets globally are poorly understood.

OBJECTIVE

We generate evidence on adolescent diets globally and explore patterns and trends by subpopulation.

METHODS

We estimated mean frequency of consumption and prevalence of less-than-daily fruit and vegetable consumption, at-least-daily carbonated beverage consumption, and at-least-weekly fast-food consumption among school-going adolescents aged primarily 12 to 17 years from the Global School-based Student Health Surveys in Africa, Asia, Oceania, and Latin America between 2008 and 2015. Random-effects meta-analysis was used to pool estimates globally and by subgroup.

RESULTS

On average, adolescents consumed fruit 1.43 (95% confidence interval [CI] 1.26-1.60) times per day, vegetables 1.75 (1.58-1.92) times per day, carbonated soft drinks 0.99 (0.77-1.22) times per day, and fast food 1.05 (0.78-1.32) times per week. Overall, 34.5% (95% CI 29.4-39.7) consumed fruit less than once per day, 20.6% (15.8-25.9) consumed vegetables less than once per day, 42.8% (35.2-50.7) drank carbonated soft drinks at least once per day, and 46.1% (38.6-53.7) consumed fast food at least once per week. Mean daily frequency of fruit consumption was particularly low in South and East Asia (1.30 [1.02-1.58]); carbonated soft drink consumption high in Latin America (1.54 [1.31-1.78]), high-income countries (1.66 [1.29-2.03]), and modern food system typologies (1.44 [0.75-2.12]); and mean weekly fast food consumption high in mixed food system typologies (1.29 [0.88-1.71]).

CONCLUSIONS

School-going adolescents infrequently consume fruits and vegetables and frequently consume carbonated soft drinks, but there is wide variability by subpopulation.
