Personal, proxy, and collective food agency among early adolescents

Interaction effect of screen time and sugar-sweetened beverages with depressive symptoms in adolescents: evidence from a large sample-based survey in China

Excessive screen time and the consumption of sugar-sweetened beverages are found to be independent predictors of depressive symptoms. However, the potential interaction effect of screen time and sugar-sweetened beverages, that is, whether one exposure factor strengthens the association of another with depressive symptoms, remains unclear. A large-scale adolescent health surveillance survey was conducted in 27 schools in eight regions across China. A total of 22,868 students were recruited to complete an eligible questionnaire to provide details of their screen time and sugar-sweetened beverage consumption. Depressive symptoms were assessed using the Patient Health Questionnaire (PHQ-9). Multiplicative and additive interaction models were performed to estimate the interaction effects of screen time and sugar-sweetened beverages on depressive symptoms, and whether the relationship varied by age group was also examined. The multivariate logistic regression model showed that even if the confounding factors were controlled, screen time and sugar-sweetened beverages were still risk factors for depressive symptoms in adolescents. Interaction models indicated that screen time and sugar-sweetened beverages in combination were related to greater odds of depressive symptoms. Compared with late adolescents, early adolescents had a higher probability of depressive symptoms when exposed to the joint effects. Our study may hopefully deepen the understanding of the association between screen time and sugar-sweetened beverages and depressive symptoms. Future research should further explore how and why screen time and sugar-sweetened beverages affect individuals more profoundly in early adolescence than in late adolescence and how to mitigate this.

Screen Time Use and Ultra-Processed Food Consumption in Adolescents: A Focus Group Qualitative Study

BACKGROUND

Sedentary lifestyles and ultra-processed food (UPF) consumption contribute to a high prevalence of overweight and obesity among adolescents. Screen time may be associated with higher UPF consumption and affect eating behaviors substantially.

OBJECTIVE

The aim of this study was to explore adolescents' perceptions, attitudes, and motivations concerning the consumption of UPF when using screens; investigate their perceived educational needs regarding nutrition; and explore their knowledge about UPF.

DESIGN

This was a qualitative study using focus groups.

PARTICIPANTS/SETTING

Four focus groups with 30 adolescents aged 12 to 16 years at a Spanish high school were recruited in May 2022. Participants were chosen using purposive sampling based on a theoretical saturation criterion.

ANALYSES

Focus group discussions were audio-recorded, transcribed verbatim, and analyzed using inductive thematic analysis.

RESULTS

Three themes emerged from the thematic analysis. Participants explained that most of their meals were eaten in front of screens. They confirmed more consumption of UPF at breakfast, as mid-afternoon snacks, on weekends, and during their main meals when alone. Participants reported that the high consumption of UPF during social gatherings was related to its easy availability, convenience, and palatability. Adolescents expressed that eating in front of screens and exposure to UPF advertising led to compulsive and impulsive consumption of these products. They described UPF as addictive and unhealthy. Although participants had little awareness of UPF health effects, they expressed interest in learning about healthy eating habits. Parental attitudes toward food were considered by the participants as relevant in establishing their eating behaviors.

CONCLUSIONS

Loneliness, social gatherings, and parental attitudes toward UPF consumption emerged as important influences on adolescents' dietary behaviors in front of screens. In addition, availability, palatability, and exposure to advertising were key factors reported to influence adolescents' UPF consumption in front of screens. Addressing these influences through nutritional and educational interventions, as well as regulating the adolescent obesogenic environment and managing screen time could help modulate these effects.

The Association between Federal Nutrition Assistance Programs and Adolescent Food Security during the COVID-19 Pandemic: Evidence from Baltimore, Maryland

Given the lack of attention on adolescent food insecurity, the primary objective of this study was to assess the association of household participation in federal food assistance programs with food security status among adolescents in Baltimore during the COVID-19 pandemic. Adolescents, ages 14-19 years, were invited to participate in two online surveys. The baseline was implemented between October 2020 and January 2021, while the follow-up took place one year later from November 2021 to January 2022 after schools had re-opened. We then matched survey participants with household participation in food nutrition assistance programs using data obtained from the Maryland Department of Social Services. We used logistic regression to examine the association between food assistance program participation status and food insecurity. Additionally, to examine whether the impact of program participation on food insecurity changed between the baseline survey and one year later at follow-up when schools re-opened, a difference-in-differences analysis was conducted. The results showed no significant associations between adolescent food security and participation in any of the federal nutrition assistance programs. Increased attention on how best to improve adolescent food security in low-income households that can respond to the unique needs of adolescents is clearly warranted.

Correlates of eating behaviors in adolescence: a systematic review of qualitative studies

CONTEXT

Nutrition plays a critical role in adolescence. Adolescents are vulnerable to the impact of different factors that distance them from healthy habits, increasing their risk of chronic diseases in adulthood. Qualitative methodologies allow for a better understanding of these factors.

OBJECTIVE

This systematic review aims to consolidate qualitative research evidence from the past 10 years to analyze the facilitators and barriers influencing adolescents' eating behaviors.

DATA SOURCES

Databases searched for relevant studies were Scopus, Medline/PubMed, PsycINFO, and Web of Science.

DATA EXTRACTION

A total of 4176 records were identified. The authors used the GRADE-CERQual (Confidence in Evidence from Reviews of Qualitative Research) quality-assessment tool.

RESULTS

Fifty articles with qualitative or mixed methodologies were finally included. The most applied techniques were focus groups and semi-structured interviews. The factors influencing adolescents' diets were classified into 4 dimensions: individual, social, community, and macrosystem factors. The most influential were the following-(1) at the individual level: gender (facilitator or barrier), taste and appearance of food (barrier), and lack of time (barrier); (2) at the social level: parents' and caregivers' influence (facilitator or barrier), peer group influence (barrier), and socioeconomic position (barrier); (3) at the community level: school food environment (facilitator or barrier), neighborhood food environment (barrier), household food environment (facilitator or barrier), food insecurity (barrier), and availability and affordability of ultra-processed foods (barrier); and (4) at the macrosystem level: digital tools (facilitator or barrier).

CONCLUSIONS

This systematic review identified several facilitators and barriers influencing eating behaviors among adolescents. Qualitative research provides a rich source of knowledge to inform interventions aimed at improving adolescents' diets. Qualitative research is very useful for collecting researches that help to implement intervention programs that improve adolescent nutrition.

Meat reduction meets family reality: Negotiating sustainable diets in households with adolescents

Limited research exists on how the transition towards more sustainable eating takes place at the meso-level of family decision-making, or how children and adolescents engage in and possibly influence the process towards more sustainable diets in families. In this paper, we study how public recommendations that encourage reducing the consumption of meat for the benefit of both health and climate are interpreted, negotiated, and acted upon in Danish families with adolescents (aged 15-20) residing at home. We use novel methodological stimuli, including vignettes and a visual sorting task, embedded in qualitative, in-depth interviews to elicit data on parents' and adolescents' everyday meat consumption/reduction behaviours. Findings reveal that a desire to uphold harmony and family cohesion serves as simultaneous drivers and barriers to reducing meat consumption. Further, we identify barriers to change in the gendered work hidden in the tasks of planning the integration of more sustainable, green dishes into the meal repertoires. Implications are drawn for social marketers, marketers, and public policymakers, encouraging these to use insights into family food decision-making processes as a lever to facilitate the needed green transition of diets in family households.

Indian adolescents' perceptions of anaemia and its preventive measures: Aqualitative study

High prevalence of anaemia is a severe public health problem in several low- and middle-income countries like India. A qualitative inquiry was designed to understand the perceptions of adolescents regarding anaemia and anaemia prevention measures. Convenience sampling was employed to recruit 39 adolescents (19 girls; 20 boys) from Tikari, India. Interviews were carried out in the local language, audio-recorded and transcribed verbatim. Hemoglobin concentration was also assessed from a single drop of capillary blood using the HemoCue, and the participants were asked to share their Science/Biology and Home Science textbooks. Interview data was analysed thematically. Descriptive statistics were used to examine the distributions of the hemoglobin data while textbooks were analysed using content analysis to verify the coverage of anaemia and anaemia-related matter. Seven themes were identified: (i) Poor understanding of the term anaemia; (ii) Minimal discussion about anaemia in classroom; (iii) Limited knowledge about symptoms of anaemia; (iv) Limited awareness about prevention and cure of anaemia; (v) Perception of iron folic acid and deworming tablets among students; (vi) Lack of contribution of health workers in the prevention of anaemia; (vii) No knowledge of 'Anemia free India' programme. More than half of the sample had anaemia (16.7% mild anaemia, 33.3% moderate anaemia, 2.8% severe anaemia). Content analysis revealed that there was limited discussion about anaemia in both Home Science and Science textbooks. Behavioural interventions should focus on inculcating healthy culinary and dietary practices and addressing the gaps in knowledge and understanding of anaemia and its prevention among adolescents.

Complex, Varied and Evolving Manifestations of Food Agency in Daily Life Among Diabetes Prevention Program Participants in Baltimore, Maryland

OBJECTIVE

To characterize food agency (one's capacity to procure and prepare food in particular contexts) among Diabetes Prevention Program (DPP) participants and gather perspectives about experiences with DPP.

DESIGN

Photograph-elicitation in-depth interviews and survey measures.

SETTING

Baltimore, Maryland (June-August 2021).

PARTICIPANTS

Black women (n = 13) who participated in DPP.

PHENOMENON OF INTEREST

Food agency and strategies used to procure and prepare food and the influence of DPP on daily food behaviors. Surveys measured food agency using the Cooking and Food Provisioning Action Scale and cooking behaviors.

ANALYSIS

Thematic analysis of qualitative in-depth interviews and descriptive statistics for quantitative measures.

RESULTS

As quantitative and qualitative data revealed, participants were frequent and confident cooks with high food agency. Participants viewed cooking as a key strategy for healthy eating and desired more hands-on cooking instruction within DPP to develop new healthy cooking skills. The primary barriers identified were related to lack of time or energy. Food procurement and preparation practices shifted over time, and DPP was a key influence on current behaviors.

CONCLUSIONS AND IMPLICATIONS

Food agency is complex and manifests heterogeneously in daily life. A life course, contextual, and food agency-based approach could be considered for future diabetes prevention interventions.

Involvement of Brazilian adolescents in home cooking: An exploratory analysis (EVA-JF Study)

OBJECTIVE

The aim of this study was to investigate the involvement of Brazilian adolescents in home cooking, estimating its associations with sex and socioeconomic status.

METHODS

This cross-sectional study involved a probabilistic sample of 14- to 19-y-olds enrolled in 29 public schools in the municipality of Juiz de Fora, MG, Southeast Brazil (n = 835). To assess involvement in home cooking, a 12-question questionnaire was used. The content was based on the Brazilian Food Guide, which encourages the acquisition, development, and sharing of culinary skills. Pearson's χ test and Poisson regression models were carried out, without and with adjustments.

RESULTS

Most of the adolescents did not usually participate in meal planning (61%), and in the choice/purchase of food and culinary ingredients (67%). Boys were less likely to know how to cook "from scratch", positively self-evaluate their culinary skills, enjoy cooking, wish to learn more about cooking and meal preparation, and to participate frequently in the planning and preparation of meals. Belonging to a lower socioeconomic status represented a greater probability of preparing meals alone for the family.

CONCLUSIONS

We verified an alarming prevalence of adolescents with behaviors unaligned with Brazilian Food Guide recommendations; that is, most of them, especially boys, were not involved in home cooking. Adolescence may present a window of opportunity for the development of culinary skills, resulting in long-term benefits for the population's diet quality. Furthermore, to change a historical pattern that overloads women's daily lives, it is necessary to encourage, from an early age, the presence of boys in the kitchen.
