U.S. Adolescents' Diet Consumption Patterns Differ between Grocery and Convenience Stores: National Health and Nutrition Examination Survey 2011-2018

Using coupons to encourage healthier child snack purchases in corner stores: results from the CHOMPS study

Objectives

To examine youths' (ages 6-15 years) autonomous snack purchases in corner stores and pilot use of coupons to encourage more healthful snack purchases.

Methods

This pilot study involved four corner stores proximal to K-8 schools in Massachusetts. Kids-only coupons of varying discounts were provided in store and paired with simple visual and verbal economic and health messages. Observational data about youths' autonomous snack purchases was recorded pre- and post-intervention. Outcomes of interest were snack item, price, and nutrient content. Comparisons of purchase characteristics and nutritional content across intervention conditions were made using Chi-squared and t-tests.

Results

Across all stores, 2,973 purchase observations were recorded totaling approximately $6,000. Researchers estimated that about 55% of shoppers were 10-12 years old. Modest coupon usage (2.2% of purchases) was noted. However, candy purchases decreased, and the percentage of purchase events that included at least one healthier food item more than doubled, regardless of coupon use. Improvements in the nutritional content of snacks were also observed.

Conclusion

Kids-only coupons have the potential to assist with shifting autonomous snack purchase behavior in outside of school settings.

Consumption Trends and Eating Context of Lentils and Dried Peas in the United States: A Nationally Representative Study

BACKGROUND

Incorporation of lentils and dried peas could form the basis of a nutrient-rich diet; yet, they are among the least-consumed legumes in the United States (US). The objective of this study was to examine the prevalence of lentils/dried peas consumption in the US over time and across socio-demographic groups, as well as to examine the eating context of these foods.

METHODS

Analyses included adults (aged 18 years or older) and children (aged 3-17 years) participating in National Health and Nutrition Examination Survey (NHANES) 2003-2004 through 2017-2018. Participants consuming lentils/dried peas on one or both of the 24-h dietary recalls were categorized as consumers.

RESULTS

Although an increasing time trend in prevalence of consumption was observed over the study period, prevalence of lentils/dried peas consumption was less than 7% in NHANES 2017-2018 in adults and children. Demographic differences were observed, such that a greater proportion of non-Hispanic Asians were classified as consumers. Lentils/dried peas were primarily obtained from grocery stores and supermarkets.

CONCLUSIONS

Although there are signs of rising acceptance of dried peas and lentils, the low prevalence of lentils/dried peas consumption suggests that understanding barriers to consumption of these foods could further identify opportunities to improve their consumption.

Effectiveness of the "Planning Health in School" Programme on Children's Nutritional Status

Effective interventions for guiding children to change behaviours are needed to tackle obesity. We evaluated the effectiveness of the 'Planning Health in School' programme (PHS-pro) on children's nutritional status. A non-randomised control group pretest-posttest trial was conducted at elementary schools of a sub-urban municipality in Porto's metropolitan area (Portugal). A total of 504 children of grade-6, aged 10-14, were assigned in two groups: children of one school as the intervention group (IG), and three schools as the control group (CG). Anthropometric measures included height, weight, waist circumference (WC), BMI and waist-to-height ratio (WHtR), and lifestyle behaviours (self-reported questionnaire) were assessed at baseline and after PHS-pro. IG children grew significantly taller more than CG ones (p < 0.001). WC had reduced significantly in IG (-0.4 cm) whereas in the CG had increased (+0.3 cm; p = 0.015), and WHtR of IG showed a significant reduction (p = 0.002) compared with CG. After PHS-pro, IG children consumed significantly fewer soft drinks (p = 0.043) and ate more fruit and vegetables daily than CG. Physical activity time increased significantly in IG (p = 0.022), while CG maintained the same activity level. The PHS-pro did improve anthropometric outcomes effectively leading to better nutritional status and appears to be promising in reducing overweight and obesity.
