Smartphone use while eating increases caloric ingestion

Associations between body mass index and episodic memory for recent eating, mindful eating, and cognitive distraction: A cross-sectional study

Objectives

Eating while distracted has been associated with a higher body mass index (BMI), whereas mindful eating and episodic memory for recent eating have shown the opposite pattern. This pre-registered, global study (https://osf.io/rdjzk) compared the relative association between these variables (and four "positive controls": restraint, disinhibition, emotional eating, plate clearing) and self-reported BMI. The timing of data collection (April-May 2020) during the SARS-CoV-2 pandemic enabled an investigation of the impact of stay-at-home restrictions imposed on the UK population on the measures of eating behavior.

Methods

An online survey was completed, including: (i) demographic data (e.g., self-reported BMI), (ii) Likert ratings assessing episodic memory for recent eating, mindful eating, cognitive distraction, restrained eating, emotional eating, disinhibition and plate clearing over the last 12 months and the last 7 days (during the first UK COVID-19 lockdown), and (iii) the Mindful Eating Questionnaire (MEQ).

Results

A large adult sample participated (N = 846; mean (SD) age = 33.0 (14.3) years; mean (SD) BMI = 24.6 (5.6) kg/m2). Mindful eating (MEQ-total score) was associated with a lower self-reported BMI (β = -0.12; 95% CI = -0.20, -0.04; p = 0.004), whereas disinhibited eating was associated with a higher self-reported BMI (β = 0.30; 95% CI = 0.21, 0.38; p < 0.001). In UK participants (n = 520), consistent changes in eating behavior during lockdown were not found. For those that did experience change, decreases were reported in; emotional eating, disinhibited eating, focusing on taste during a meal (a measure of mindful eating), and using a smart phone while eating.

Conclusions

These findings provide evidence in a large global sample for associations between BMI and (i) mindful eating, and (ii) disinhibited eating. Future research should evaluate whether mindful eating demonstrates a prospective association with body weight and should consider mechanisms of action.

A Randomized Controlled Trial, Non-Nutrition Based mHealth Program: The Potential Impact on Dietary Intake in College Students

The aims of this study were to (1) explore this sample's pre- and post-intervention dietary intake, specifically the macro- and micronutrients, and their eating habits related to location of consumption and use of electronic devices, and (2) compare this sample's nutritional measures to the current Dietary Guidelines 2020 to 2025. Twenty-eight participants were included in the secondary data analysis. Participants reported a total of 822 items consumed during this study. Most items were consumed at home (n = 629, 76.5%). We found significant differences in the intake of energy, protein, total fat, carbohydrates, total vegetables, total grains, and total meat in different locations. For most of these measures, consumption at home and/or restaurants resulted in a greater magnitude of consumption than at other locations (e.g., car, daycare). Participants reported consuming most of their energy and nutrients while either using electronic devices alone (n = 365, 44.4%) or using no devices (n = 346, 42.1%). Significant differences were found among three measures including energy, total fat, and total fiber. The majority of the macronutrients (total fiber, fruits, vegetables, meat, and dairy) consumed by our sample were under the threshold recommended in the 2020 to 2025 Dietary Guidelines.

Mindful eating: A conceptual critical review of the literature, measurement and intervention development

Background: Defining mindful eating and discussing all it entails has proven to be abstract, open-ended and biased to the interpretation of the researchers and authors in the field. Despite some consensus, different interpretations have led to different psychometric tools and practices not descriptive of mindful eating, contributing towards a replication crisis. Aim/Method: This narrative review will draw on the most appropriate definition of mindful eating in the framework of traditional secular mindfulness literature and discuss how mindful eating psychometrics and practices are unsuitable for precise research. Results/Discussion: A proposal and directive of separation between eating behaviours and decision-making in mindful eating as a way of developing evidence-based practices and psychometric tools are proposed for both clinical and non-clinical use.

Encouraging (Nudging) People to Increase Their Fluid Intake

This narrative historical review considers the various routes to nudging consumers towards drinking more, given self-reported evidence that many people are often not adequately hydrated. This review builds on the related notion of 'visual hunger'. Interestingly, however, while many desirable foods are associated with distinctive sensory qualities (such as an appetizing smell), that may capture the consumer's (visual) attention, it is less clear that there is an equivalent sensory attentional capture by hydration-related cues. One of the other important differences between satiety and thirst is that people tend to overconsume if they use interoceptive satiety cues to decide when to stop eating, while the evidence suggests that people typically stop drinking prior to being adequately hydrated. What is more, the increasing amount of time we spend in consistently warm indoor environments may also be exacerbating our need to drink more. A number of concrete suggestions are made concerning how people may be encouraged (or nudged) to imbibe sufficient water.

Smartphone Usage Patterns and Dietary Risk Factors in Adolescents

BACKGROUND

Whereas earlier studies have shown that traditional screen time such as TV watching influences dietary behaviors in adolescents, little is known about the effects of modern screen time such as smartphone use.

OBJECTIVES

We examined the associations of smartphone usage duration and content type with dietary risk factors among adolescents.

METHODS

We conducted a cross-sectional analysis using a nationally representative sample of 54,601 middle- and high-school students (aged 12-18 y; 26,928 boys and 27,673 girls) in the Korea Youth Risk Behavior Web-Based Survey 2017. Smartphone use (average duration and most frequently used content type) and dietary intakes [frequent breakfast skipping; less frequent intakes of fruits and vegetables; more frequent intakes of instant noodles, fast food, chips/crackers, and sugar-sweetened beverages (SSBs)] were self-reported via an online-based questionnaire. Multivariable logistic regression was performed to estimate ORs and 95% CIs for the associations of smartphone usage duration and content type with prevalence of dietary risk factors, adjusting for potential confounders. All analyses accounted for complex survey sampling.

RESULTS

Prolonged smartphone use (≥300 compared with 1-59 min/d) was associated with (OR; 95% CI) higher prevalence of frequent breakfast skipping (1.60; 1.45, 1.76); frequent intakes of instant noodles (1.65; 1.47, 1.84), fast food (1.36; 1.20, 1.53), and SSBs (1.92; 1.75, 2.11); and less frequent intakes of fruits (1.44; 1.30, 1.59) and vegetables (1.32; 1.18, 1.47). Adjusting for usage duration, using smartphones mainly for messenger/e-mail, social networking service (SNS)/forum, and games were associated with less frequent intakes of fruits (OR: 1.21; 95% CI: 1.12, 1.31; OR: 1.28; 95% CI: 1.17, 1.40; and OR: 1.20; 95% CI: 1.10, 1.32, respectively) and vegetables (OR: 1.24; 95% CI: 1.12, 1.37; OR: 1.26; 95% CI: 1.13, 1.40; and OR: 1.25; 95% CI: 1.12, 1.40, respectively) than was using smartphones for education/information search. Using smartphones mainly for messenger/e-mail (OR: 1.24; 95% CI: 1.14, 1.35) and SNS/forum (OR: 1.18; 95% CI: 1.08, 1.29) were also associated with more frequent intake of SSBs.

CONCLUSIONS

Our data suggest that both duration and content type of smartphone use are independently associated with dietary risk factors among adolescents.

Risks of Digital Screen Time and Recommendations for Mitigating Adverse Outcomes in Children and Adolescents

BACKGROUND

The COVID-19 pandemic caused an unprecedented move to emergency remote learning around the world, leading to increased digital screen time for children and adolescents. This review highlights the potential risk of increased screen time to the eye and general health and makes recommendations to mitigate the risks posed.

METHODS

A narrative review of evidence of increased digital time during the COVID-19 pandemic, the risks linked to increased screen time and offer possible steps to mitigate these in students.

RESULTS

Digital screen time was found to have increased for children and adolescents in all the studies examined during the pandemic and data suggests that this has an impact on eye and general health. We discuss the associated risk factors and adverse outcomes associated with increased digital screen time.

CONCLUSIONS

This review offers evidence of increased digital time, highlights some of the well-known and not so well-known risks linked to increased screen time, and offers possible steps to mitigate these in children and adolescents during the pandemic, as well as offering schools and parents strategies to support the eye health of children and adolescents post-pandemic. We discuss a number of interventions to reduce the risk of eye strain, myopia, obesity, and related diseases that have been shown to be linked to increased digital screen time.

Impact of gastroplasty on salivary characteristics, dental health status and oral sensory aspects: a controlled clinical study

BACKGROUND

Saliva is a non-invasive source of biomarkers useful in the study of different pathophysiological conditions. The qualitative and quantitative study of saliva, as well as the assessment of oral health, can be particularly useful for a better understanding of obesity due to its importance in the food oral perception and ingestion.

OBJECTIVES

To evaluate the effect of treatment of morbid obesity (dietary counselling versus gastroplasty) on salivary characteristics, oral sensory perception and dental health in a controlled study.

METHODS

73 adults (60 females; 19-59 years) with morbid obesity were divided in: Control group (CG; n=34) followed-up during a 6-months dietary program, and Gastroplasty group (GG; n=39) evaluated immediately before, 3, and 6 months after gastroplasty. Dietary habits, Oral Health Impact Profile and xerostomia complaints were investigated by interview. The clinical examination included anthropometric and caries experience evaluation. Salivary flow rate, buffering capacity, total protein and alpha-amylase levels, and sensitivity for the 4 basic tastes were assessed. Two-way mixed model and sign test were applied.

RESULTS

Physical and clinical aspects did not differ between groups in the beginning of the study, and GG showed a rapid weight loss after surgery (p<0.001). An improvement in most of the dietary aspects was observed, especially in the GG. A worsening in the dental health status was observed over time in both groups, with an increase in the number of filled and decayed teeth. CG showed a better oral health-related quality of life, while xerostomia complains increased in GG after gastroplasty. Salivary flow rate remained stable in both groups, but a decrease in buffering capacity, total protein, and alpha-amylase activity was observed in GG after 6-months; taste sensitivity increased from baseline to 6-months in GG (p<0.05).

CONCLUSION

After 6-months of follow-up, patients undergoing gastroplasty presented an improvement in dietary habits and taste sensitivity. However, changes in saliva composition and a worsening in dental health status and xerostomia complaints were also observed.

Food Addiction and Emotional Eating Behaviors Co-Occurring with Problematic Smartphone Use in Adolescents?

Addiction in adolescence is increasing and has a significant impact on physical and mental health. Notably, addictions can be comorbid and affect each other. Despite the recent growing interest in food addiction (FA) and problematic smartphone use (PSU), few studies have investigated their association in adolescents. We investigated the relationship between FA and PSU in adolescents and the effects of eating behaviors. A total of 209 adolescents (44.5% male; mean age = 12.86 ± 0.7 years) participated in the current school-based community study. We found a positive correlation between the dimensional Yale Food Addiction Scale for Children 2.0 (dYFAS-C2.0) and the Smartphone Overdependence Scale after adjusting for age, sex, body mass index, and socioeconomic status. The high-risk PSU group accounted for 17.2% of participants. Furthermore, this group showed 2.3 times higher dYFAS-C2.0 scores than the general group. Emotional overeating and satiety responsiveness were correlated with PSU. A comprehensive evaluation of addiction symptoms is needed for proper intervention, especially in adolescents with symptoms of abnormal eating behaviors.

Influence of eating with distractors on caloric intake of children and adolescents: a systematic review and meta-analysis of interventional controlled studies

Eating habits developed during childhood can be perpetuated along life and contribute to the emergence of disorders. We aimed to investigate the influence of distractors during experimental meals on the energy intake of children and adolescents. We followed the PRISMA guidelines and the study was registered in PROSPERO (CRD42021259946). The PICOS strategy consisted of children and adolescents (P), exposed to distractors during meals (I), compared with no distraction (C) and the outcome was energy intake (Kcal) (O) evaluated in crossover and parallel randomized clinical trials (RCTs) (S). Searches were conducted in PubMed, Scopus, Web of Science, Cochrane, Proquest, Embase, and LILACs databases. We employed RoB 2 tool and NutriGrade. Databases searches returned 9,576 references. Thirteen articles were selected (five crossover and eight parallel RCTs). Volunteers aged 3 to 17 years-old. All studies evaluated TV as distractor. Most studies presented high/moderate risk of bias. Meta-analysis of parallel RCT indicated no significant difference in energy intake while eating with TV (MD = 0.05; 95% CI -0.13 - 0.23, P = 0.57), with moderate certainty level. In conclusion, under laboratory conditions, eating with distractors seems to barely alter energy intake for children and adolescents.Supplemental data for this article is available online at https://doi.org/10.1080/10408398.2022.2055525 .

Solo Dining at Home in the Company of ICT Devices

The consumption of a solo meal is often subject to negative associations. Studies indicate that solo diners use information and communication technology (ICT) devices such as smartphones, to mitigate negative experiences such as boredom and loneliness, especially when dining in a public context. However, we know less about the motivation to use such devices and consequent meal experiences in a private context. For this exploratory qualitative study, we asked participants to fill out a cultural probe kit to capture their dining experience and use of ICT devices over a period of seven days. Once completed, the content was discussed with participants during a semi-structured interview. Data was analyzed using thematic analysis in a deductive and inductive form leading to four themes: (1) The experience of eating with others; (2) The use of electronic devices while eating; (3) The meaning of food; and (4) Relaxing features and influences. Participants indicated that eating alone can be a pleasurable experience that people enjoy and perceive as relaxing. ICT devices were named to play an essential part in the dining experience. The entertainment that devices provide can mitigate feelings of loneliness and uncomfortable silence when eating by oneself. We reflect on the findings and point out potential design avenues for future studies.

Association between daily smartphone use and consumption: Should we put the phones down?

Previous research has established that eating while viewing television is related to increased calorie consumption. However, despite the growing prevalence of smartphone use in daily life, very little research has investigated the relationship between phone use and eating behavior. Moreover, what little research exists has all been laboratory-based. The present study sought to fill this research gap by investigating smartphone use and eating behavior in everyday life. One hundred and thirty eight participants logged all foods and drinks consumed using MyFitnessPal and submitted smartphone screen time data for three consecutive days (Thursday through Saturday). Results revealed no significant associations between smartphone use and calorie consumption on any of the three study days. Additionally, morning phone use did not predict calories eaten during subsequent meals on any day. The type of phone use (e.g., social networking, reading, etc.) was also not related to total daily calorie intake. These findings on eating behavior in daily life contradict laboratory research, suggesting that smartphone use may not promote increased calorie intake in the same way that television viewing does.

Relationship between eating disorders and internet and smartphone addiction in college students

PURPOSE

This study was planned and conducted to determine the relation between eating behavior disorder and smartphones and the internet in college students.

METHODS

This research was performed on a total of 437 college students, including 116 males and 321 females. A questionnaire questioning the general characteristics (age, sex, department, socioeconomic status, skipping meal, number of main meals and snacks in a day, sleeping duration, doing physical activity, height, and body weight) of students was used. In addition, Eating Attitude Test-40 (EAT-40), Young's Internet Addiction Scale, and Smartphone Addiction Scale were used to measure eating behavior disorders, internet addiction, and smartphone addiction, respectively. Height and body weight were measured in accordance with the method.

RESULTS

12.6% of the students participating in the study were at risk for eating disorders. Female students had higher EAT-40 scores than male students. 13% of students had potential internet addiction. According to Pearson chi-square test, the prevalence of potential internet addiction (36.4%) in students with eating disorder was higher than those without eating disorder (9.7%) (p < 0.05). Pearson correlation analyses displayed that Smartphone Addiction Test score associated positively with EAT-40 score (r = 0.277) and Internet Addiction Test score (r = 0.665) and students' body mass index (BMI) (r = 0.121). In addition to these, students' duration of staying on the internet correlated with their BMI (r = 0.137). Males had a higher rate of potential internet addiction than females (22.4% in males and 9.7% in females, respectively) (p < 0.05).

CONCLUSION

The present results suggest that students' duration of using the internet affects smartphone addiction and internet addiction, both of which influence eating behavior disorder. In addition, both smartphone and internet addiction and eating behavior disorder correlated positively and significantly with overweight.

LEVEL OF EVIDENCE

Level V: cross-sectional descriptive study.

The use of ICT devices as part of the solo eating experience

An increasing number of people tend to eat alone due to social changes and an altered attitude towards cooking and eating practices. Anecdotal reports indicate that solo diners tend to use information and communication technology devices, for example, the smartphone, as part of the eating experience. While lab studies suggest that the devices contribute to an increased high-calorie food intake and decreased feeling of satiety, these studies disregard the everyday experience and motivation of solo diners. We conducted an exploratory study to investigate how solo diners use digital devices as part of their daily eating experience. Semi-structured interviews with solo diners (N = 12) were analyzed using thematic analysis in an inductive approach leading to six themes. The themes focus on (1) the perception of a meal; (2) the experience of a solo diner; (3) the purpose of using an information and communication technology device; (4) the perceived influence of the devices; (5) factors decreasing and increasing the use; (6) and the potential to promote healthier food consumption. Our results indicate that the use of digital devices while eating alone can lead to distraction, being unaware of the food texture and the amount that is eaten. The devices can also induce a positive influence by providing entertainment and mitigating negative emotions like loneliness and boredom. The devices have the potential to contribute to healthy eating practices by providing education and by influencing the speed of eating through elements of sound. Although the use of devices might negatively affect eating behavior, their ubiquitous presence also offers the opportunity to reach specific, vulnerable populations.

How Digital Food Affects Our Analog Lives: The Impact of Food Photography on Healthy Eating Behavior

Obesity continues to be a global issue. In recent years, researchers have started to question the role of our novel yet ubiquitous use of digital media in the development of obesity. With the recent COVID-19 outbreak affecting almost all aspects of society, many people have moved their social eating activities into the digital space, making the question as relevant as ever. The bombardment of appetizing food images and photography – colloquially referred to as “food porn” – has become a significant aspect of the digital food experience. This review presents an overview of whether and how the (1) viewing, (2) creating, and (3) online sharing of digital food photography can influence consumer eating behavior. Moreover, this review provides an outlook of future research opportunities, both to close the gaps in our scientific understanding of the physiological and psychological interaction between digital food photography and actual eating behavior, and, from a practical viewpoint, to optimize our digital food media habits to support an obesity-preventive lifestyle. We do not want to rest on the idea that food imagery’s current prevalence is a core negative influence per se. Instead, we offer the view that active participation in food photography, in conjunction with a selective use of food-related digital media, might contribute to healthy body weight management and enhanced meal pleasure.

Using Smartphones When Eating Increases Caloric Intake in Young People: An Overview of the Literature

Recent literature highlights that the use of smartphones during meals increases the number of calories ingested in young people. Although the distraction interferes with physiological signals of hunger and satiety, a social facilitation effect has also been suggested. Cognition is a pivotal component in regulating food intake, and activities requiring high perceptual demands should be discouraged during meals.

The impact of active or passive food preparation versus distraction on eating behaviour: An experimental study

Research indicates a role for attention in the perception of hunger and food intake. The present experimental study aimed to explore the impact of attention to food cues through either active or passive food preparation, versus attention away from food cues through a non-food distraction task on eating behaviour using a preload/taste test design. Female participants (n = 80) were randomly allocated to one of four conditions: active food preparation (making a wrap); passive video preparation (watching video of researcher making a wrap); distraction (a non-food colouring task); no time control. Measures of desire to eat (hunger, fullness, motivation) were taken before and after the interventions. Food intake was measured in terms of mass of wrap consumed and snacks consumed at a subsequent taste test. The results showed greater wrap consumption for active and passive food preparation and the control groups compared to the distraction intervention. Further, the results showed that active food preparation resulted in increased hunger and motivation to eat and that passive food preparation resulted in increased motivation to eat. No changes were found following distraction. To conclude, attention to food cues through both active and passive food preparation can increase both food intake and the desire to eat. The implications for promoting changes in eating behaviour are discussed.

Oral Health and Nutritional Characteristics of Adults With Morbid Obesity: A Multivariate Analysis

The relationship between oral health and nutritional aspects are complex, especially in individuals with chronic diseases and comorbidities, such as morbid obesity. Thus, the aim of the present study was to identify oral health and nutritional-related patterns in 113 individuals, aged 19–68 years (92 females), seeking treatment for morbid obesity. Sociodemographic variables and medical records were examined, in addition to the consumption of fruit, vegetables, candies, and processed foods. Measures of body mass index, neck, waist and hip, caries experience (DMFT index), Community Periodontal Index (CPI index), and salivary physicochemical aspects were gathered. Aspects of oral health-related quality of life and symptoms of dry mouth were evaluated by means of Oral Health Impact Profile (OHIP-14) and Xerostomia Inventory-XI questionnaires. K-means cluster analysis and, subsequently, comparisons between clusters (one-way ANOVA) were performed (α = 5%). Three clusters were generated: Cluster 1 (labeled “Young”; n = 77) was characterized by younger participants with higher BMI, who reported the use of distractors while eating, the smallest number of meals/day, and who consumed sweetened drinks and processed food the day before. Cluster 2 (labeled “Diabetic individuals”; n = 12) was characterized by older participants with the highest proportion of diabetic participants (100% were diabetic; 73% insulin users), lower BMI, higher DMFT index and OHIP-14 and xerostomia scores, and who reported having consumed fruit and vegetables the day before. Finally, Cluster 3 (labeled “Poor periodontal health”; n = 24) was characterized by participants with the worse periodontal condition (higher CPI), and lower salivary flow, pH, and buffer capacity. Cluster 1 and 2 were the groups that showed higher demand for nutritional and dietetic counseling, because of the poor eating behavior and higher serum glucose levels, respectively. On the other hand, Cluster 2 and 3 showed the higher demand for oral rehabilitation and dental treatment because of the loss of teeth and worse periodontal condition, respectively, besides the need for dietetic counseling. This sample of individuals with morbid obesity showed very unique oral-health and nutritional characteristics and special needs patterns that should be identified to adjust or change unhealthy habits, thus improving the assistance of this condition.

Edograms: recording the microstructure of meal intake in humans-a window on appetite mechanisms

Early attempts at the objective measurement of food intake in humans followed many heuristic pioneer studies in laboratory animals, which revealed how homeostatic and hedonic factors interact to shape the daily eating patterns. Early studies in humans examined the characteristics of intake responses at discrete ingestive events. Described for the first time in 1969, the edogram consisted of a parallel recording of chewing and swallowing responses during standardized lunches, allowing parameters of the "microstructure of meals" to be quantified under varying conditions of deprivation or sensory stimulation, in parallel with overall meal size, meal duration, and eating rate. Edographic studies showed consistent changes in the microstructure of meals in response to palatability level (increased eating rate, decreased chewing time and number of chews per food unit, shorter intrameal pauses, and increased prandial drinking under improved palatability). Longer premeal deprivation affected the eating responses at the beginning of meals (decreased chewing time and number of chews per food unit) but not at the end. Eating rate decelerated during the course of meals in normal-weight participants but not in participants with obesity. These observations largely agreed with contemporary works using other objective measurement methods. They were confirmed and expanded in later studies, notably in the investigation of satiation mechanisms affecting weight control. Importantly, research has demonstrated that the parameters of the microstructure of meals not only reflect the influence of stimulatory/inhibitory factors but can, per se, exert a causal role in satiation and satiety. The early edographic recording instruments were improved over the years and taken out of laboratory settings in order to address the measurement of spontaneous intake responses in free-living individuals. Much remains to be done to make these instruments entirely reliable under the immense variety of situations where food consumption occurs.

Taste sensitivity and lifestyle are associated with food preferences and BMI in children

Oral food perception together with lifestyle may affect food preferences and choices, influencing weight gain and obesity development. The present study was designed to evaluate the association of biological (taste sensitivity) and lifestyle variables with children food preferences, assessing whether all these variables contribute to explain BMI percentile. After anthropometric evaluation, 387 children were classified for bitter and sweet taste sensitivities. Socioeconomic/lifestyle aspects and hedonics for 36 foods were collected. Watching TV during meals associate with lower preference for several vegetables, as well as being sweet taste low sensitive, in the case of girls. Moreover, regression analysis showed that bitter taste sensitivity is one of the variables contributing to explain high BMI percentiles. These results present evidences that both biological and socioeconomic and the attention that is given to food (eating in the presence or absence of distractors) are aspects that should be considered in children nutrition to prevent obesity.

[Association of mobile phone overuse with sleep disorder and unhealthy eating behaviors in college students of a medical university in Guangzhou]

OBJECTIVE

To investigate the association of mobile phone use with sleep disorder and unhealthy eating behavior among college students of a medical university in Guangzhou.

METHODS

Mobile Phone Involvement Questionnaire (MPIQ), Pittsburgh Sleep Quality Index (PSQI) and the Three Factor Eating Questionnaire Revised 21 Item (TFEQ-R21) were used to survey 2122 undergraduates of the medical university. One-sample t test, One-way ANOVA and multiple linear regression analysis were used to analyze the data.

RESULTS

Age, body mass index (BMI), phone use before sleep, phone use frequency, sleep quality (assessed by total PSQI score) and the dimension scores of TFEQ-R21 for uncontrolled eating, cognitive restraint, and emotional eating were all significantly correlated with the total score of MPIQ (P < 0.05). Phone use before sleep, high frequency of mobile phone use, poor sleep quality and emotional eating were associated with high MPIQ scores, while lower cognitive restraint and emotional eating tendency were correlated with lower scores of MPIQ. Bivariate analysis revealed that age (r=0.088, P < 0.001), BMI (r=0.055, P < 0.05), PSQI scores (r=0.204, P < 0.001), TFEQ-UE scores (r=0.199, P < 0.001), TFEQ-CR scores (r=-0.076, P < 0.001), TFEQ-EE scores (r=0.170, P < 0.001), phone use before sleep (r=0.429, P < 0.001), and phone use frequency (r=0.316, P < 0.001) were all significantly correlated with MPIQ scores; multiple linear regression analysis showed that model 4 incorporating the scores of TFEQ-UE, TFEQ-CR, and TFEQ-EE explained up to 21.8% of the main effect (adjusted R2= 21.5%).

CONCLUSIONS

Mobile phone overuse is associated with poor sleep quality and unhealthy eating behaviors, and education and interventions for mobile phone use is essential among college students.

Electronic device use and beverage related sugar and caffeine intake in US adolescents

Background

Despite recent declines in consumption of sugary beverages, energy drinks (ED) and sodas continue to contribute a substantial amount of sugar and caffeine to the diet of youth. Consumption of these beverages has been linked with electronic device use, however in-depth associations between sugar and caffeine intake from energy drinks and sodas with various electronic devices are not clear.

Objective

Describe the relationship of soda and energy drink consumption and associated added sugar and caffeine intake with electronic device use among adolescents.

Methods

Secondary data from the 2013–2016 cycles of Monitoring the Future Survey, a national, repeated, cross-sectional study, were analyzed. Information on energy drink and soda consumption by students in grades 8 and 10 (n = 32,418) from 252–263 schools randomly sampled from all US states was used.

Results

Soda and energy drink consumption decreased each year from 2013–2016 while daily use of electronic devices remained stable. An additional hour/day of TV was linked to a 6.92g (6.31,7.48; p<0.001) increase in sugar intake and a 32% (OR = 1.32; 1.29,1.35; p < .001) higher risk of exceeding World Health Organization (WHO) recommended sugar intakes. Further, each hour/day of TV was linked to a 28% increased risk of exceeding caffeine recommendations (OR = 1.25–1.31; p<0.001). Each hour per day talking on a cellphone was associated with an increased risk of exceeding WHO sugar and caffeine intakes by 14% (OR = 1.11–1.16; p<0.001) and 18% (OR = 1.15–1.21; p<0.001) respectively. Video game use was only weakly linked to caffeine intake. Computer use for school was associated with lower likelihood of exceeding sugar intake cut-offs.

Conclusion

While a trend towards reduced energy drink and soda intake from 2013–2016 was evident, greater electronic device use, especially TV time, was linked to higher intake of beverage-derived added sugar and caffeine amongst adolescents. Addressing these behaviours through counselling or health promotion could potentially help to reduce excess sugar and caffeine intake from sodas and energy drinks among this population.

Digital Commensality: Eating and Drinking in the Company of Technology

Commensality is a key aspect of social dining. However, previous research has identified a number of pros and cons associated with the incorporation of digital technology into eating and drinking episodes. For instance, those who are distracted by digital technology may eat/drink more (that is, they may overconsume) as a result of their failure to attend to the food-related sensations that are thought to cue the termination of eating. Similarly, it has often been suggested that the use of mobile devices at mealtimes can disrupt the more commensal aspects of dining/drinking (at least among those who are physically present together). At the same time, however, looking to the future, it seems clear that digital technologies also hold the promise of delivering opportunities for enhanced multisensory experiential dining. For instance, they might be used to match the auditory, visual, or audiovisual entertainment to the eating/drinking episode (e.g., think only about watching a Bollywood movie while eating a home-delivery Indian meal, say). Indeed, given the growing societal problems associated with people dining by themselves, there are a number of routes by which digital technologies may increasingly help to connect the solo diner with physically co-located, remote, or even virtual dining partners. In this review of the literature, our focus is specifically on the role of technology in inhibiting/facilitating the more pleasurable social aspects of dining, what one might call "digital commensality." The focus is primarily on Westernized adults with reasonable access to, and familiarity with, digital technologies.

Meal-Concurrent Media Use is Associated with Increased Dietary Intake with no Evidence of Next Meal Compensation in Free-Living Adults

OBJECTIVE

This study aimed to determine the effects of concurrent and prior media use on dietary intake and dietary compensation over 3 days in a free-living population.

METHODS

Participants recorded food intake and media use for a 3-day period. The US Department of Agriculture multiple-pass method was used to ensure completeness of food records. Energy, protein, fiber, carbohydrates, sugar, added sugar, fat, saturated fat, trans fat, and sodium intake were assessed.

RESULTS

Meals consumed while participants used media included 149.3 more calories on average than meals consumed without media. Media meals were higher in protein, carbohydrates, fat, and saturated fat. There was no evidence of dietary compensation at the meal following the media meal.

CONCLUSIONS

Energy and macronutrient intake increased during media-paired meals. Dietary compensation at the subsequent meal did not occur, suggesting that the effects of media-paired meals are additive over the short term.

Attending to the Chemical Senses

Theorizing around the topic of attention and its role in human information processing largely emerged out of research on the so-called spatial senses: vision, audition, and to a lesser extent, touch. Thus far, the chemical senses have received far less research interest (or should that be attention) from those experimental psychologists and cognitive neuroscientists interested in the topic. Nevertheless, this review highlights the key role that attentional selection also plays in chemosensory information processing and awareness. Indeed, many of the same theoretical approaches/experimental paradigms that were originally developed in the context of the spatial senses, can be (and in some cases already have been) extended to provide a useful framework for thinking about the perception of taste/flavour. Furthermore, a number of those creative individuals interested in modifying the perception of taste/flavour by manipulating product-extrinsic cues (such as, for example, music in the case of sonic seasoning) are increasingly looking to attentional accounts in order to help explain the empirical phenomena that they are starting to uncover. However, separate from its role in explaining sonic seasoning, gaining a better understanding of the role of attentional distraction in modulating our eating/drinking behaviours really ought to be a topic of growing societal concern. This is because distracted diners (e.g., those who eat while watching TV, fiddling with a mobile device or smartphone, or even while driving) consume significantly more than those who mindfully pay attention to the sensations associated with eating and drinking.
