  • Impact of New Transport Infrastructure on Walking, Cycling, and Physical Activity
    Item type: Journal Article

    Walking and cycling bring health and environmental benefits, but there is little robust evidence that changing the built environment promotes these activities in populations. This study evaluated the effects of new transport infrastructure on active commuting and physical activity.

    Introduction There has been limited research investigating whether small financial incentives can promote participation, behavior change, and engagement in physical activity promotion programs. This study evaluates the effects of two types of small financial incentives within a physical activity promotion program of a Swiss health insurance company. Study design Three-arm cluster-randomized trial comparing small personal financial incentives and charity financial incentives (10 Swiss Francs, equal to US$10.40) for each month with an average step count of >10,000 steps per day to control. Insureds’ federal state of residence was the unit of randomization. Data were collected in 2015 and analyses were completed in 2018. Setting/participants German-speaking insureds of a large health insurer in Switzerland were invited. Invited insureds were aged ≥18 years, enrolled in complementary insurance plans and registered on the insurer's online platform. Main outcome measures Primary outcome was the participation rate. Secondary outcomes were steps per day, the proportion of participant days in which >10,000 steps were achieved and non-usage attrition over the first 3 months of the program. Results Participation rate was 5.94% in the personal financial incentive group (OR=1.96, 95% CI=1.55, 2.49) and 4.98% in the charity financial incentive group (OR=1.59, 95% CI=1.25, 2.01) compared with 3.23% in the control group. At the start of the program, the charity financial group had a 12% higher chance of walking 10,000 steps per day than the control group (OR=1.68, 95% CI=1.23, 2.30), but this effect dissipated after 3 months. Steps per day and non-usage attrition did not differ significantly between the groups. Conclusions Small personal and charity financial incentives can increase participation in physical activity promotion programs. Incentives may need to be modified in order to prevent attrition and promote behavior change over a longer period of time.

  • Impact of the Food and Drug Administration's Proposed Front-of-Package Label and Alternative Designs on Consumer Understanding: A Randomized Experiment
    Item type: Journal Article

    Introduction: In January 2025, the Food and Drug Administration proposed mandating Nutrition Info front-of-package labels, which would indicate whether packaged foods are low, medium, or high in saturated fat, sodium, and added sugars. This study examined whether a label similar to the Food and Drug Administration's proposal improves consumer understanding compared with positive endorsement and other proposed or adopted front-of-package labels and whether effects vary by income, education, race/ethnicity, and nutrition literacy. Study design: This was an online RCT conducted in October–November 2024. Setting/participants: National sample of 5,636 U.S. adults who were primary grocery shoppers. Intervention: Participants were randomized to 1 of 6 front-of-package labeling systems: (1) positive (reference group), (2) Nutrition Info (the Food and Drug Administration proposal), (3) high-in nutrient (warnings for high levels of nutrients of concern), (4) positive + Nutrition Info, (5) positive + high-in, and (6) spectrum (rates products from least to most healthy). Main outcome measures: Participants viewed 6 pairs of products with their assigned labels and indicated which product they thought was healthier in each pair. Consumer understanding was measured by correct identification of the healthier product across product pairs. Analyses were conducted in 2025. Results: Across product pairs, participants correctly identified the healthier option 56%–90% of the time. Compared with positive labels, Nutrition Info labels led to the greatest improvements in consumer understanding (difference: 18.4 percentage points), followed by positive + Nutrition Info (17.9 percentage points), positive + high-in (11.8 percentage points), spectrum (10.8 percentage points), and high-in (5.3 percentage points) (ps<0.001). Effects did not differ by income, education, or race/ethnicity but differed by nutrition literacy (p-interaction<0.01). Labels improved understanding more for higher-literacy than for lower-literacy participants, with the largest differences for Nutrition Info and positive + Nutrition Info labels. Conclusions: Findings support the Food and Drug Administration's initiative to implement mandatory front-of-package labels. Nutrition Info labels improved consumer understanding the most but may not serve all nutrition literacy groups equally. Trial registration: NCT06516627.
