Using a Socioecological Approach to Identify Factors Associated with Adolescent Sugar-Sweetened Beverage Intake

Kids SIPsmartER reduces sugar-sweetened beverages among Appalachian middle-school students and their caregivers: a cluster randomized controlled trial

BACKGROUND

High consumption of sugar-sweetened beverages (SSB) is a global health concern. Additionally, sugar-sweetened beverage (SSB) consumption is disproportionately high among adolescents and adults in rural Appalachia. The primary study objective is to determine the intervention effects of Kids SIPsmartER on students' SSB consumption. Secondary objectives focus on caregivers' SSB consumption and secondary student and caregiver outcomes [e.g, body mass index (BMI), quality of life (QOL)].

METHODS

This Type 1 hybrid, cluster randomized controlled trial includes 12 Appalachian middle schools (6 randomized to Kids SIPsmartER and 6 to control). Kids SIPsmartER is a 6-month, 12 lesson, multi-level, school-based, behavior and health literacy program aimed at reducing SSB among 7th grade middle school students. The program also incorporates a two-way text message strategy for caregivers. In this primary prevention intervention, all 7th grade students and their caregivers from participating schools were eligible to participate, regardless of baseline SSB consumption. Validated instruments were used to assess SSB behaviors and QOL. Height and weight were objectively measured in students and self-reported by caregivers. Analyses included modified two-part models with time fixed effects that controlled for relevant demographics and included school cluster robust standard errors.

RESULTS

Of the 526 students and 220 caregivers, mean (SD) ages were 12.7 (0.5) and 40.6 (6.7) years, respectively. Students were 55% female. Caregivers were mostly female (95%) and White (93%); 25% had a high school education or less and 33% had an annual household income less than $50,000. Regardless of SSB intake at baseline and relative to control participants, SSB significantly decreased among students [-7.2 ounces/day (95% CI = -10.7, -3.7); p < 0.001, effect size (ES) = 0.35] and caregivers [-6.3 ounces/day (95% CI = -11.3, -1.3); p = 0.014, ES = 0.33]. Among students (42%) and caregivers (28%) who consumed > 24 SSB ounces/day at baseline (i.e., high consumers), the ES increased to 0.45 and 0.95, respectively. There were no significant effects for student or caregiver QOL indicators or objectively measured student BMI; however, caregiver self-reported BMI significantly decreased in the intervention versus control schools (p = 0.001).

CONCLUSIONS

Kids SIPsmartER was effective at reducing SSB consumption among students and their caregivers in the rural, medically underserved Appalachian region. Importantly, SSB effects were even stronger among students and caregivers who were high consumers at baseline.

Assessing sugar-sweetened beverage consumption in early pregnancy using a substance abuse framework

Sugar-sweetened beverages (SSB) are previously reported to jeopardize maternal fetal health, most well-known for gestational diabetes, childhood obesity, and cognitive impairment. Although warnings and diet recommendations urge pregnant women to consume less SSB, there is no noticeable difference in their behavior. How and why reproductive women change their SSB consumption patterns were not investigated previously. Our study aims to investigate beverage consumption patterns and how these patterns change in pregnancy in the context of substance use disorder (SUD). We invited all pregnant women visiting the clinic to answer a structured 20-min questionnaire every trimester during the regular antennal visit. At the end of the study, 337 pregnant women aged over 20 participated. A total of 301 responses entered for final analysis, with a response rate of 89.3%. Our finding showed those with high DSM-5-TR scores reduced SSB intake after becoming pregnant, while those with mild or low DSM-5-TR scores increased SSB intake after becoming pregnant. The top 3 factors related to their SSB consumption were "use despite of known health hazard (n = 133)", "increased desire to drink (n = 88)", and "excessive time spent on seeking SSB (n = 85)". The least reported factors were in the domains of social impairment (ranging from n = 3 to n = 26), pharmacologic effects (i.e., tolerance (n = 24) and withdrawal (n = 70). When participants reduced SSB consumption after becoming pregnant, their choice of beverages largely shifted to sugarless beverage but not much plain water. The result provided new insights in deciphering pregnant women's psychomotor factors for SSB intake, which served as useful references for making clinical or even public health recommendations.

Outcomes of a Caregiver-Focused Short Message Service (SMS) Intervention to Reduce Intake of Sugar-Sweetened Beverages in Rural Caregivers and Adolescents

This study examined enrollment, retention, engagement, and behavior changes from a caregiver short message service (SMS) component of a larger school-based sugar-sweetened beverage (SSB) reduction intervention. Over 22 weeks, caregivers of seventh graders in 10 Appalachian middle schools received a two-way SMS Baseline Assessment and four monthly follow-up assessments to report their and their child's SSB intake and select a personalized strategy topic. Between assessments, caregivers received two weekly one-way messages: one information or infographic message and one strategy message. Of 1873 caregivers, 542 (29%) enrolled by completing the SMS Baseline Assessment. Three-quarters completed Assessments 2-5, with 84% retained at Assessment 5. Reminders, used to encourage adherence, improved completion by 19-40%, with 18-33% completing after the first two reminders. Most caregivers (72-93%) selected a personalized strategy and an average of 28% viewed infographic messages. Between Baseline and Assessment 5, daily SSB intake frequency significantly (p < 0.01) declined for caregivers (-0.32 (0.03), effect size (ES) = 0.51) and children (-0.26 (0.01), ES = 0.53). Effect sizes increased when limited to participants who consumed SSB twice or more per week (caregivers ES = 0.65, children ES = 0.67). Findings indicate that an SMS-delivered intervention is promising for engaging rural caregivers of middle school students and improving SSB behaviors.

Retention and engagement of rural caregivers of adolescents in a short message service intervention to reduce sugar-sweetened beverage intake

Objective

This study investigates a 6-month short message service (SMS) intervention to reduce adolescent sugar-sweetened beverage (SSB) intake. The objectives are to describe caregiver retention and SMS engagement as well as explore differences by caregiver characteristics.

Methods

Caregivers completed a baseline survey then messages were sent two times per week. Message types included the following: SSB intake assessments, educational information, infographic URLs, and strategies. Engagement was measured through interaction with these messages and included: assessment completion, reminders needed, number of strategies chosen, and URLs clicked.

Results

Caregivers (n = 357) had an average baseline SSB intake of 23.9 (SD = 26.8) oz/day. Of those, 89% were retained. Caregivers with a greater income and education were retained at a higher rate. Average engagement included: 4.1 (SD = 1.3) of 5 assessments completed with few reminders needed [4.1 (SD = 3.7) of 14 possible], 3.2 (SD = 1.1) of 4 strategies selected, and 1.2 (SD = 1.6) of 5 URLs clicked. Overall, average engagement was relatively high, even where disparities were found. Demographic characteristics that were statistically related to lower engagement included younger age, lower income, lower educational attainment, single caregivers, lower health literacy. Furthermore, caregivers with a reduced intention to change SSB behaviors completed fewer assessments and needed more reminders. Higher baseline SSB intake was associated with lower engagement across all indicators except URL clicks.

Conclusions

Results can be used to develop targeted retention and engagement strategies (e.g., just-in-time and/or adaptive interventions) in rural SMS interventions for identified demographic subsets.

Is Adolescents' Free Sugar Intake Associated with the Free Sugar Intake of Their Parents?

High free sugar intake can lead to increased dental caries, obesity, and other health risks among adolescents. Studies have shown that family factors, especially parents, are one of the primary factors influencing adolescents' sugar intake. This study aims to investigate the influence of adolescent parents' free sugar intake, knowledge, attitude, and practice (KAP) on adolescents' free sugar intake. A total of 1090 pairs of adolescents and their parents from 10 secondary schools in Changsha were enrolled in a cross-sectional study. Free sugar intakes of parents and adolescents were measured using the food frequency questionnaire (FFQ). The current status of parents' knowledge, attitude, and practice in consuming free sugar was investigated using online and offline questionnaires. Parental free sugar intake was 11.55 (5.08, 21.95) g/d, and that of adolescents was 41.13 (19.06, 80.58) g/d. Parental free sugar intake, free sugar knowledge level, intake behavior, and guidance behavior were associated with adolescent free sugar intake. A superior level of parental free sugar knowledge (adjusted OR = 0.726, 95% CI: 0.557~0.946) was a protective factor for adolescent free sugar intake. Moderate and high levels of parental free sugar intake (adjusted OR = 1.706, 95% CI: 1.212~2.401; adjusted OR = 2.372, 95% CI: 1.492~3.773, respectively) were risk factors for free sugar intake in adolescents. Given the importance of parental influence on the adolescent free sugar intake, further limiting parental intake and increasing awareness of free sugars could play an active role in future interventions for adolescents' free sugar intake.

'I Knew I Should Stop, but I Couldn't Control Myself': a qualitative study to explore the factors influencing adolescents' consumption of sugar-sweetened beverages and sugary snacks from a socio-ecological perspective

OBJECTIVE

To explore the factors influencing Taiwanese adolescents' consumption of sugar-sweetened beverages (SSB) and sugary snacks from a socio-ecological perspective.

DESIGN

This study adopted a qualitative design by using face-to-face, in-depth interviews guided by a semistructured questionnaire.

SETTING

Eight junior high schools in New Taipei City and Changhua County, Taiwan, September to November 2018.

PARTICIPANTS

Fifty-nine participants aged 12-14 years participated in this study.

RESULTS

Reflexive thematic analysis was used to analyse the data. This study identified four themes to address the multifaceted factors that influence adolescents' consumption of SSB and sugary snacks. At the intrapersonal level, physiological factors, psychological factors, individual economic factors and taste preferences were mentioned in connection with people's consumption of SSB and sugary snacks. Positive or negative influences of parents, siblings, peers and teachers on SSB and sugary snack intake were identified at the interpersonal level. The availability of SSB and sugary snacks at home, their availability in vending machines or in school stores in the school environment and participants' access to convenience stores and hand-shaken drink shops in the broader community influenced SSB and sugary snack consumption. Additionally, food culture and food advertising were identified as influencing societal factors.

CONCLUSIONS

Overall, this qualitative study determined not only that the consumption of SSB and sugary snacks is influenced by intrapersonal factors but also that interpersonal, environmental and societal factors affect adolescents' increased sugar intake. The findings are helpful to broaden the options for designing and developing interventions to decrease SSB and sugary snack consumption by adolescents.

Factors Influencing the Sugar-Sweetened Beverage Intake of Caregivers of Adolescents in Appalachia

OBJECTIVE

To identify factors that influence the sugar-sweetened beverage (SSB) intake of caregivers of middle school-aged adolescents.

DESIGN

Cross-sectional.

SETTING

Southwestern Virginia, US, part of Central Appalachia.

PARTICIPANTS

Caregivers (n = 362) of adolescents enrolled in the Kids SIPsmartER trial. Participants were mostly female (91%) and non-Hispanic White (96%), and 21% received Supplemental Nutrition Assistance Program (SNAP) benefits.

MAIN OUTCOME MEASURES

Caregiver daily SSB intake and demographics, personal-level, interpersonal-level, and environmental-level determinants.

ANALYSIS

Descriptive statistics, 1-way ANOVA, and stepwise regression.

RESULTS

On average, caregivers consumed 25.7 (SD, 33.2) fluid ounces of SSB per day. In the final model, which included all variables, age (β = -0.41; P < 0.05), receiving SNAP benefits (β = 14.19; P ≤ 0.01), behavioral intentions (β = -5.48; P ≤ 0.001), affective attitudes (β = -2.15, P < 0.05), perceptions of whether their adolescent frequently consumes high amounts of SSB (β = 1.92; P ≤ 0.001), and home availability (β = 7.43; P ≤ 0.01) were significantly associated with SSB intake.

CONCLUSIONS AND IMPLICATIONS

Caregivers of Appalachian middle school students are high SSB consumers. Findings highlight the importance of implementing behavioral interventions for caregivers of adolescents that target multiple levels of influence, including demographic, personal-level, interpersonal-level, and environmental-level factors. Interventions may be particularly important for communities and groups with higher SSB intakes, such as those in Appalachia and who receive SNAP benefits.

Dietary Intake and Sources of Added Sugars in Various Food Environments in Costa Rican Adolescents

Consumption of added sugars, especially from sugar-sweetened beverages (SSBs), has been associated with several negative health outcomes during adolescence. This study aimed to identify dietary intake and food sources of added sugars in the home, school, and neighborhood environments of Costa Rican adolescents. Dietary intake of added sugars was determined using 3-day food records in a cross-sectional study of 818 adolescents aged 12 to 19 and enrolled in rural and urban schools in the province of San José. On average, 90% of adolescents consumed more than 10% of their total energy intake from added sugars. Furthermore, 74.0% of added sugars were provided at home, 17.4% at school, and 8.6% in the neighborhood. Added sugars were primarily provided by frescos (29.4%), fruit-flavored still drinks (22.9%), and sugar-sweetened carbonated beverages (12.3%), for a total contribution of 64.6%. Our findings suggest that Costa Rican adolescents have a plethora of added sugar sources in all food environments where they socialize. However, it is relevant for public health to consider the home and school environments as fundamental units of interventions aimed at reducing added sugars in the adolescent diet. Frescos prepared at home and school and fruit-flavored still drinks must be the focus of these interventions.

The association of food parenting practices with adolescents' dietary behaviors differ by youth gender, but not by parent gender

BACKGROUND

Parents affect their adolescents' dietary behaviors through food parenting practices both directly and indirectly through adolescents' cognitive factors (self-efficacy, intrinsic or extrinsic motivation). However, it is not known if mothers and fathers use of different food parenting practices similarly influences boys' and girls' dietary behaviors. This study investigated the direct and indirect associations between food parenting practices and adolescents' dietary behaviors (fruits/vegetables and sugar sweetened beverage (SSB)) and whether these associations differed by adolescents' or parents' gender.

METHODS

Data were obtained from the 2014 Family Life, Activity, Sun, Health, and Eating Study. A sample of 1633 American adolescent-parent dyads (73.7% mothers; 50.4% girls) completed the self-reported tools. Models were stratified by adolescents' gender and differences by parent gender were explored as a moderator.

RESULTS

Differences did not emerge based on gender of parents. However, associations between food parenting practices and adolescents' dietary behaviors differed by adolescents' gender. Direct associations between autonomy supportive food parenting practices and fruit/vegetable intake (β = 0.18, p < .05) and intrinsic motivations and SSB consumption (β = -0.13, p < .05) were detected only among boys. Direct associations, regardless of gender, were also found including structured food parenting practices and adolescent self-efficacy with their dietary behaviors; controlling food parenting practices with SSB intake; as well as intrinsic and extrinsic motivation with fruit/vegetable intake. Findings from the mediation analyses supported these trends with structured parenting practices displaying similar associations on boys' and girls' dietary behaviors were controlling and autonomy supportive parenting practices have significant indirect associations on boys' dietary behaviors through motivation pathways, but not girls.

CONCLUSION

Adolescent boys and girls appear to be affected differently by food parenting practices and accounting for these differences may contribute to more effective dietary interventions.

Applying the socio-ecological model to understand factors associated with sugar-sweetened beverage behaviours among rural Appalachian adolescents

OBJECTIVE

The objective of the current study was to identify factors across the socio-ecological model (SEM) associated with adolescents' sugar-sweetened beverage (SSB) intake.

DESIGN

This cross-sectional study surveyed adolescents using previously validated instruments. Analyses included descriptive statistics, ANOVA tests and stepwise nonlinear regression models (i.e., two-part models) adjusted to be cluster robust. Guided by SEM, a four-step model was used to identify factors associated with adolescent SSB intake - step 1: demographics (i.e., age, gender), step 2: intrapersonal (i.e., theory of planned behaviour (attitudes, subjective norms, perceived behavioural control, behavioural intentions), health literacy, media literacy, public health literacy), step 3: interpersonal (i.e., caregiver's SSB behaviours, caregiver's SSB rules) and step 4: environmental (i.e., home SSB availability) level variables.

SETTING

Eight middle schools across four rural southwest Virginia counties in Appalachia.

PARTICIPANTS

Seven hundred ninety seventh grade students (55·4 % female, 44·6 % males, mean age 12 (sd 0·5) years).

RESULTS

Mean SSB intake was 36·3 (sd 42·5) fluid ounces or 433·4 (sd 493·6) calories per day. In the final step of the regression model, seven variables significantly explained adolescent's SSB consumption: behavioural intention (P < 0·05), affective attitude (P < 0·05), perceived behavioural control (P < 0·05), health literacy (P < 0·001), caregiver behaviours (P < 0·05), caregiver rules (P < 0·05) and home availability (P < 0·001).

CONCLUSIONS

SSB intake among adolescents in rural Appalachia was nearly three times above national mean. Home environment was the strongest predictor of adolescent SSB intake, followed by caregiver rules, caregiver behaviours and health literacy. Future interventions targeting these factors may provide the greatest opportunity to improve adolescent SSB intake.
