Association between screen time and the variation of food intake markers among school-aged adolescents in Niterói/RJ, Brazil

Abstract Background Changes in eating habits may be associated with sedentary behaviors by favoring excessive weight gain among adolescents, and consequently leading to the occurrence of chronic Non-Communicable Diseases (NCD). Objective To evaluate the association between screen time and consumption of healthy and unhealthy food markers in adolescents. Method A longitudinal study with adolescents aged from 10-16 years of public schools in Niterói, in the state of Rio de Janeiro/Brazil was performed in 2014. It was applied a questionnaire about screen time, food consumption frequency and socio-demographic variables. Generalized linear models were applied with p-value <0.05. Results 448 students participated in the study, 54.8% were male, and 67% were in the category of ≥5 hours/day of total screen time and 69% in the ≤4 hours/day of television time (TV time). It was not observed an association between total screen time and food intake variations. However, an inverse association was observed between TV time and vegetable consumption (p-value = 0.02). Conclusion It was not observed an association between total screen time and food intake variations. Nevertheless, it was verified that time spent watching television was associated with consumption of vegetables. Thus, it is suggested that the reduction of the time spent in sedentary activities and healthy food choices are priorities in the elaboration of public policies.

The objectives of this study were (a) to report grade level prevalence in physical activity and sedentary behaviors and (b) to examine academic burden associations with these behaviors. School-aged children (n = 48,118) reported their physical activity, perception of physical activity sufficiency, factors for activity insufficiency, homework hours, and screen time in a typical week. Data were analyzed using general linear models and logistic regression models of Complex Samples. Prevalence results showed that children had lower physical activity and lower screen viewing time, but higher homework time during transition grades (6th, 9th, and 12th) and high school years. Academic burden was cited as the primary reason for not having sufficient physical activity (76.6%). Compared to those citing academic burden, students who did not report academic burden were significantly more likely to meet physical activity guidelines (Odds Ratio (OR) = 5.38, 95% CI = 4.74–6.11), but less likely to meet screen time guidelines (OR = 0.78, 95% CI = 0.72–0.84), controlling for body mass index, gender, and grade level. Additionally, children who reported academic burdens had significantly longer average daily homework time than those who did not (p<0.01). Policy makers should promote physical activity and help children find a balance between homework and physical activity time particularly among the educational transition grades.

Abstract Objective: To evaluate energetic contribution according to the degree of industrial food processing and its association with sociodemographic, anthropometric, biochemical, clinical and behavioural characteristics in adolescents. Design: Cross-sectional study (Adolescent Lifestyle Study). Food consumption was assessed using 24-h dietary recalls, with foods classified by degree of industrial progressing. The usual diet was estimated using the Multiple Source Method. In a linear regression model, the energy percentage (E %) was associated with sociodemographic, anthropometric, biochemical, clinical and behavioural characteristics, after adjustment for sex and age. Setting: Juiz de Fora, Brazil. Participants: Eight hundred and four adolescents, of both sexes, 14–19 years of age, enrolled in public schools. Results: The E % of unprocessed or minimally processed foods corresponded to 43·1 %, processed foods to 11·0 % and the ultraprocessed foods to 45·9 %. E % of unprocessed foods was associated with socio-economic stratum (adjusted β = −0·093; P = 0·032), neck circumference (adjusted β = 0·017; P = 0·049), screen time (adjusted β = −0·247; P = 0·036) and HDL-cholesterol (adjusted β = −0·156; P = 0·003). E % of ultraprocessed foods was associated with socio-economic stratum (adjusted β = 0·118; P = 0·011), screen time (adjusted β = 0·375; P = 0·003), BMI (adjusted β = −0·029; P = 0·025), neck circumference (adjusted β = −0·017; P = 0·028) and HDL-cholesterol (adjusted β = 0·150; P = 0·002). Conclusions: There was a high E % of ultraprocessed foods in the diet of the adolescents. Actions are needed to raise the awareness of adopting healthy eating habits.

The Impact

Objective: To provide an overview of what is known about the impact of COVID-19 on weight and weight-related behaviors. Methods: Systematic scoping review using the Arksey and O’Malley methodology. Results: A total of 19 out of 396 articles were included. All studies were conducted using online self-report surveys. The average age of respondents ranged from 19 to 47 years old, comprised of more females. Almost one-half and one-fifth of the respondents gained and lost weight during the COVID-19 pandemic, respectively. Among articles that examined weight, diet and physical activity changes concurrently, weight gain was reported alongside a 36.3% to 59.6% increase in total food consumption and a 67.4% to 61.4% decrease in physical activities. Weight gain predictors included female sex, middle-age, increased appetite, snacking after dinner, less physical exercise, sedentary behaviors of ≥6 h/day, low water consumption and less sleep at night. Included articles did not illustrate significant associations between alcohol consumption, screen time, education, place of living and employment status, although sedentary behaviors, including screen time, did increase significantly. Conclusions: Examining behavioral differences alone is insufficient in predicting weight status. Future research could examine differences in personality and coping mechanisms to design more personalized and effective weight management interventions.

Abstract Objective: To evaluate the effectiveness of a behaviourally focused nutrition education (NE) intervention based on the Health Belief Model (HBM) to improve knowledge, attitudes and practices (KAP) related to eating habits and activity levels in 10–12-year-old adolescents in Mumbai, India. Design: School-based cluster randomised controlled trial. The experimental group (EG) received weekly NE and three parent sessions over 12 weeks; no sessions were conducted for the control group (CG). The theoretical framework of HBM and focus group discussion results guided the development of behaviour change communication strategies and NE aids. KAP were measured using a validated survey instrument, administered at baseline and endline in EG and CG. Paired and independent t tests determined within-group and between-group changes in pre–post scores. Setting: Two aided and two private schools that were randomly allocated to either an EG or CG. Participants: Adolescent boys and girls (n 498; EG n 292 and CG n 206). Results: EG reported improvements in mean knowledge (39·3%), attitude (7·3 %), diet (9·6 %) and activity practice (9·4%) scores from pre to post intervention. No significant changes were observed in CG. Significant improvements in scores associated with perceived benefits, barriers and self-efficacy, breakfast and vegetable consumption, and moderate-to-vigorous activities were observed in EG. Conclusions: Integrating NE into the academic curriculum and adopting evidence-based lessons that entail targeted information delivery and participatory activities can improve knowledge, foster right attitudes and facilitate better eating and activity-related practices in Indian adolescents.

End Stage

Background: The association between fruit and vegetable (FV) intake and the risk of end-stage kidney disease (ESKD) has not been examined in the general population and fully explored in chronic kidney disease (CKD). We prospectively evaluated this relationship in US representative sample of adults and evaluated consistency by the presence or absence, and severity, of CKD. Methods: We used data from the Third National Health and Nutrition Examination Survey (1988–1994) linked with the US Renal Data System, including 14,725 adults aged ≥20 years and with follow-up for ESKD through 2008. Daily FV intake was ascertained using a food frequency questionnaire. We examined the association between selected categories of FV intake and ESKD using a Fine Gray competing risk model adjusting for sociodemographics, lifestyle, clinical and nutritional factors, estimated glomerular filtration rate, and albuminuria. We evaluated whether risk varied in individuals with severe versus any CKD. Results: 230 participants (1.5%) developed ESKD during follow-up. In the adjusted model, compared to highest intake, those in lowest categories of FV intake had a higher risk of ESKD, for <2 times/day (1.45 [1.24–1.68], 2 to <3 times/day (1.40 [1.18–1.61]), 3 to <4 times/day (1.25 [1.04–1.46]), and 4 to <6 times/day (1.14 [0.97–1.31]). There was suggestion of heterogeneity (p for interaction = 0.03) with possible stronger inverse association in patients with CKD than those without CKD. After stratification, we obtained similar strong inverse association when we examined ESKD incidence across intake of FVs in participants with CKD stages 1–4 (n = 5,346) and specifically in those with CKD stages 3–4 (n = 1,084). Conclusions: Low intake of FVs was associated with higher risk of ESKD in US adults with and without CKD, supporting an emerging body of literature on the potential benefits of plant-rich diets for prevention of ESKD.

Abstract Funding Acknowledgements Type of funding sources: Public hospital(s). Main funding source(s): Dijon University Hospital France OnBehalf CLEO-CD Background Lockdown can affect tobacco smoking (TS) behaviours. Purpose To evaluate the impact of lockdown on (TS) and associated lifestyle behaviours in patients with Chronic coronary syndrome (CCS) and congestive heart failure (CHF) Methods CCS and CHF patients were invited to answer to a phone-call questionnaire during the 1st COVID-19 lockdown start Results (Table) 343 questionnaires were fit for analysis, 43 (12.5%) were current smokers (CS). CS were younger (p < 0.001), none stopped and 13 increased their consumption (main reasons were stress and boredom). CS felt more often cramped (p = 0.023). CS who increased their TS consumption showed a trend toward a higher rate of unhealthy lifestyle behaviours Conclusions During the lockdown, more than ¼ of CS with CCS or CHF increased their TS consumption and none quitted. Moreover, TS was often associated with other deleterious behaviours increasing their risk for short and long term Main results Total Non-Smokers Smokers p* N(%) 344 301 43 Age, years 67.7 ± 12.8 69.2 ± 12.2 57.2 ± 12.1 <0.001 Men/Women 229/115 197/104 32/11 0.300 CCS/CHF 220/124 185/116 36/7 0.004 Urban/Rural 163/181 137/164 26/17 0.073 Living alone at home 83(24.3) 68(22.7) 15(34.9) 0.089 COVID screening (PCR) 11(3.2) 7(2.3) 4(9.3) 0.037 Feeling cramped 19(5.5) 13(4.4) 6(14.0) 0.023 Feeling less well 75(21.9) 65(21.7) 10(23.8) 0.842 K6 ≥ 5 81(23.7) 70(23.5) 11(25.6) 0.845 Physical activity decrease 146(42.6) 125(42.1) 21(48.8) 0.323 Screen time increase 154(45.0) 130(43.5) 24(55.8) 0.100 Alcohol consumption increase 14(5.5) 11(4.9) 3(7.5) 0.419 Sleep change 83(24.6) 68(22.5) 15(39.5) 0.083 Weight increase 77(22.4) 64(21.3) 13(30.2) 0.242 Smokers (n = 43) Smoking increase No smoking increase p** Feeling less well 5(38.5) 5(17.2) 0.238 Screen time increase 10(76.9) 14(46.7) 0.104 Weight increase 6(46.2) 7(23.3) 0.173 n(%) or mean ± SD. *p value: Smokers vs non smokers. **p value: Smoking increase vs no smoking increase

Nutritional condition impacts academic performance and cognitive development. In Peru, the prevalence of chronic undernutrition in children is 6.9%, increasing the risk of mortality and morbidity. This study aimed to develop an educational intervention to achieve an improvement in the healthy habits of children in a primary education school in Lima who live in vulnerable socioeconomic conditions. We conducted a prospective quasi-experimental pre-test and post-test study of an educational intervention. The information was collected through the adaptation of the WHO questionnaire “Global School-based Student Health Survey” (GSHS), with anthropometric variables, socioeconomic level, hygiene and eating habits. One hundred eight students from 5 to 13 years old from Arenitas del Mar School in Lima (Peru) participated. The educational intervention improved eating habits. Fruit and vegetable consumption 3 or more times/day (50.9%) increased after the educational intervention (49% vs. 62.9%,) p < 0.0001. There was an improvement in hygiene habits, such as the frequency of handwashing with soap (32.4% vs. 63.9%) and the frequency of weekly bathing 4–6 times/week (25% vs. 47.5%) p < 0.0001. The educational intervention promoted better healthy living behaviors, eating habits and hygiene. This kind of initiative is a crucial tool to establish healthy living habits.

(1) Background: Adolescence is a period of increased autonomy and independent decision making; it determines health behaviors that can persist into the future. Individual factors like food choices and unhealthy lifestyle have an essential role in the development and prevention of obesity among adolescents and are associated with the nutrition literacy of parents and other adults. While the association of parents’ nutrition literacy with adolescent BMI has been addressed, there is still a scarcity of studies that examine the effect of adolescents’ nutrition literacy on their eating habits and body mass index (BMI) status. (2) Methods: A cross-sectional study was conducted that included 189 adolescents (68 with overweight and obesity and 121 with normal weight) aged between 14–19 years from four private schools in Tripoli, Lebanon. A self-administered questionnaire that included the Nutrition Literacy Assessment Instrument (NLAI) and the Adolescent Food Habits Checklist (AFHC) was used. Anthropometrics were measured using standardized procedures. The association between nutrition literacy, food habits and BMI was assessed using a chi squared test for independence and Poisson regression analysis where suitable. (3) Results: Results indicated no association between all five components of nutrition literacy and body mass index categories. Furthermore, there was no association between the Adolescent Food Habits Checklist and overweight or obese BMI status (RR = 0.947, 95%CI: 0.629–1.426) (p = 0.796). No association was observed between nutrition literacy and food habits, except for an inverse association with macronutrients literacy. (4) Conclusions: In conclusion, the study indicated that there was no association between the components of nutrition literacy with body mass index or with food habits, except for macronutrient literacy.
