Sugary Drink Consumption Among Children by Supplemental Nutrition Assistance Program Status

Association between sugar-sweetened beverage consumption frequency and muscle strength: results from a sample of Chinese adolescents

BACKGROUND

Although sugar-sweetened beverage consumption has become an important and widespread concern, there are few studies on the association between sugar-sweetened beverage consumption frequency and muscle strength in Chinese adolescents. The objective of this study was to analyze the association between sugar-sweetened beverage consumption frequency and muscle strength in Chinese adolescents.

METHODS

A stratified whole-group sampling method was used to survey 25,893 adolescents aged 13-15 years old in China for sugar-sweetened beverage consumption frequency and muscle strength for grip strength and standing long jump. The subjects' basic information, body mass index (BMI), and covariates were investigated. The association between sugar-sweetened beverage consumption frequency and muscle strength was analyzed by multivariate logisitc regression analysis.

RESULTS

The proportions of Chinese adolescents who consumed sugar-sweetened beverage ≥ 3 times/week, 1-2 times/week, and < 1 time/week were 12.23%, 52.79%, and 34.98%, respectively. The differences in sugar-sweetened beverage consumption frequency were statistically significant when compared across gender, parental education, duration of physical activity, snacks, and mode of commuting to school (χ² values = 228.570, 51.422, 275.552, 3165.656, 10.988, P < 0.01). Logistic regression analysis showed that overall Chinese adolescents with sugary drinks 1-2 times/week (OR = 1.207, 95% CI:1.132-1.287) and sugary drinks ≥ 3 times/week (OR = 1.771, 95% CI:1.611-1.947) were associated with lower muscle strength compared to sugary drinks < 1 time/week showed a positive association (P < 0.01). The same trend was found for boys and girls.

CONCLUSION

Chinese adolescents' sugar-sweetened beverage consumption is common, and high-frequency sugar-sweetened beverage consumption is associated with lower muscle strength. In the future, we should control the use of sugar-sweetened beverages and increase muscular strength training in Chinese adolescents to promote healthy growth.

Trends in Added Sugars Intake and Sources Among US Children, Adolescents, and Teens Using NHANES 2001-2018

BACKGROUND

Over the past 2 decades, there has been an increased emphasis on added sugars intake in the Dietary Guidelines for Americans (DGA), which has been accompanied by policies and interventions aimed at reducing intake, particularly among children, adolescents, and teens.

OBJECTIVES

The present study provides a comprehensive time-trends analysis of added sugars intakes and contributing sources in the diets of US children, adolescents, and teens (2-18 years) from 2001-2018, focusing on variations according to sociodemographic factors (age, sex, race and ethnicity, income), food assistance, and health-related factors (physical activity level, body weight status).

METHODS

Data from 9 consecutive 2-year cycles of the NHANES were combined and regression analyses were conducted to test for trends in added sugars intake and sources from 2001-2018 for the overall age group (2-18 years) and for 2 age subgroups (2-8 and 9-18 years). Trends were also examined on subsamples stratified by sex, race and ethnicity (Hispanic, non-Hispanic Asian, non-Hispanic Black, non-Hispanic White), income (household poverty income ratio), food assistance, physical activity level, and body weight status.

RESULTS

From 2001-2018, added sugars intakes decreased significantly (P < 0.01), from 15.6% to 12.6% kcal among children (2-8 years) and from 18.4% to 14.3% kcal among adolescents and teens (9-18 years), mainly due to significant declines in added sugars from sweetened beverages, which remained the top source. Declines in added sugars intakes were observed for all strata, albeit to varying degrees.

CONCLUSIONS

Declines in added sugars intakes were observed among children, adolescents, and teens from 2001-2018, regardless of sociodemographic factors, food assistance, physical activity level, or body weight status, but variations in the magnitudes of decline suggest persistent disparities related to race and ethnicity and to income. Despite these declines, intakes remain above the DGA recommendation; thus, continued monitoring is warranted.

Sugar-Sweetened Beverage Consumption in Children: The Interplay of Household SNAP and WIC Participation

INTRODUCTION

Although sugar-sweetened beverage (SSB) consumption is associated with Supplemental Nutrition Assistance Program (SNAP) and Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) participation, no national studies have examined the interplay between these programs. This study compares children's sugar-sweetened beverage consumption across households enrolled in one, both, or neither program.

METHODS

A total of 4 waves (2009-2010 to 2015-2016) of the National Health and Nutrition Examination Survey were combined to obtain a sample of 4,772 children aged 0-19 years living in households eligible for both SNAP and WIC (households with income ≤130% of the Federal Poverty Level). Children were grouped as living in 4 household types: SNAP only; WIC only; SNAP + WIC; and neither program. Beverages with any added sugars were classified as SSBs. Two-part regression models examined the adjusted association between SSB consumption and program participation. Analyses were conducted in 2020.

RESULTS

Compared with the SNAP‒only group, children in all other household types had lower odds of SSB consumption (AOR=0.44, p=0.002 for WIC only; AOR=0.69, p=0.020 for SNAP + WIC; AOR=0.61, p=0.025 for neither program). The lower probability of SSB consumption for children from WIC‒participating households was mostly driven by children aged 0-5 years, with the differences weakening for children aged 6-12 years and completely disappearing for those aged 12-19 years. No significant differences were observed for the amount of added sugar consumed by SSB consumers.

CONCLUSIONS

Household WIC participation-whether jointly with SNAP or alone-may confer protection against SSB consumption. Unlike SNAP, WIC, by design, provides participating households with more information and opportunities to access and consume healthier diets. Understanding how SNAP and WIC interact can help policymakers improve the design and nutritional benefit of the U.S. food safety net.

Trends in junk food consumption among US children and adults, 2001-2018

BACKGROUND

Trends in junk food consumption, a risk for obesity, are not well established.

OBJECTIVES

We examined national trends in types of junk food (excluding beverages) and their sources (grocery, restaurants, schools, etc.), overall and in population subgroups.

METHODS

We assessed 29,970 children (aged 2-19 y) and 44,501 adults (aged ≥20 y) with 24-h dietary recall data from 9 NHANES cycles (2001-2002 to 2017-2018). Trends in junk food were assessed over time using 1-d values for individuals with single recalls and 2-d means for others.

RESULTS

From 2001 to 2018, percent energy (%E) from junk food remained stable for children (from 18.1% to 17.5%, P-trend = 0.25) and decreased for adults (14.1% to 13.0%, P-trend = 0.002). Among children, increases occurred in %E from crackers (1.19% to 1.35%) and snack/meal bars (0.38% to 0.69%) and decreases in candy (2.58% to 1.96%) and other desserts (3.11% to 2.48%) (all P-trends < 0.01). Among adults, increases occurred in snack/meal bars (0.31% to 0.78%, P-trend < 0.001) and decreases in candy (1.97% to 1.55%; P-trend < 0.001), sweet bakery products (5.52% to 4.98%; P-trend = 0.04), and other desserts (2.19% to 1.86%; P-trend = 0.001). In 2017-2018, grocery stores provided the largest proportion of junk food (72.7% for children, 77.1% for adults), followed by other sources (13.1%, 12.1%), restaurants (8.05%, 9.11%), schools (4.86%), and worksites (1.99%). In both children and adults, junk food intake was higher among non-Hispanic white and black Americans compared with Mexican Americans, among those with higher compared with lower education, among women compared with men, and among older compared with younger adults. In sensitivity analyses using only 1-d recalls, mean junk food intake each cycle was ∼0.8-1.0 and 0.3-0.4%E units higher in children and adults, respectively, with otherwise similar trends and subgroup differences over time.

CONCLUSIONS

From 2001 to 2018, %E from junk food represented nearly 1 in 5 calories among children, without change, and nearly 1 in 7 calories, with modest decrease, among adults, with disparities in subgroups.

Price discounting as a hidden risk factor of energy drink consumption

OBJECTIVES

Global consumption of caffeinated energy drinks (CED) has been increasing dramatically despite increasing evidence of their adverse health effects. Temporary price discounting is a rarely investigated but potentially powerful food marketing tactic influencing purchasing of CED. Using grocery transaction records generated by food stores in Montreal, we investigated the association between price discounting and purchasing of CED across socio-economic status operationalized by education and income levels in store neighbourhood.

METHODS

The outcome, log-transformed weekly store-level sales of CED, was modelled as a function of store-level percent price discounting, store- and neighbourhood-level confounders, and an interaction term between discounting and each of tertile education and income in store neighbourhood. The model was separately fit to transactions from supermarkets, pharmacies, supercentres, and convenience stores.

RESULTS

There were 18,743, 12,437, 3965, and 49,533 weeks of CED sales from supermarkets, pharmacies, supercentres, and convenience stores, respectively. Percent price discounting was positively associated with log sales of CED for all store types, and the interaction between education and discounting was prominent in supercentres: -0.039 [95% confidence interval (CI): -0.051, -0.028] and -0.039 [95% CI: -0.057, -0.021], for middle- and high-education neighbourhoods relative to low-education neighbourhoods, respectively. Relative to low-income areas, the associations of discounting and log CED sales in supercentres for neighbourhoods with middle- and high-income tertile were 0.022 [95% CI: 0.010, 0.033] and 0.015 (95% CI: -0.001, 0.031), respectively.

CONCLUSION

Price discounting is an important driver of CED consumption and has a varying impact across community education and income.
