Beyond-brand effect of television food advertisements on food choice in children: the effects of weight status

AbstractObjectiveTo investigate the effect of television food advertising on children’s food intake, specifically whether childhood obesity is related to a greater susceptibility to food promotion.DesignThe study was a within-subject, counterbalanced design. The children were tested on two occasions separated by two weeks. One condition involved the children viewing food advertisements followed by a cartoon, in the other condition the children viewed non-food adverts followed by the same cartoon. Following the cartoon, their food intake and choice was assessed in a standard paradigm.SettingThe study was conducted in Liverpool, UK.SubjectsFifty-nine children (32 male, 27 female) aged 9–11 years were recruited from a UK school to participate in the study. Thirty-three children were normal-weight (NW), 15 overweight (OW) and 11 obese (OB).ResultsExposure to food adverts produced substantial and significant increases in energy intake in all children (P < 0·001). The increase in intake was largest in the obese children (P = 0·04). All children increased their consumption of high-fat and/or sweet energy-dense snacks in response to the adverts (P < 0·001). In the food advert condition, total intake and the intake of these specific snack items correlated with the children’s modified age- and gender-specific body mass index score.ConclusionsThese data suggest that obese and overweight children are indeed more responsive to food promotion, which specifically stimulates the intake of energy-dense snacks.

Background:The goal of this study was to establish preliminary criterion-referenced cut points for adult pedometer-determined physical activity (PA) related to weight status defined by body mass index (BMI).Methods:Researchers contributed directly measured BMI and pedometer data that had been collected (1) using a Yamax-manufactured pedometer, (2) for a minimum of 3 days, (3) on ostensibly healthy adults. The contrasting groups method was used to identify age- and gender-specific cut points for steps/d related to BMI cut points for normal weight and overweight/obesity (defined as BMI <25 and ≥25 kg/m2, respectively).Results:Data included 3127 individuals age 18 to 94 years (976 men, age = 46.8 ± 15.4 years, BMI = 27.3 ± 4.9; 2151 women, age = 47.4 ± 14.9 years, BMI = 27.6 ± 6.4; all gender differences NS). Best estimated cut points for normal versus overweight/obesity ranged from 11,000 to 12,000 steps/d for men and 8000 to 12,000 steps/d for women (consistently higher for younger age groups).Conclusions:These steps/d cut points can be used to identify individuals at risk, or the proportion of adults achieving or falling short of set cut points can be reported and compared between populations. Cut points can also be used to set intervention goals, and they can be referred to when evaluating program impact, as well as environmental and policy changes.

Obesity in childhood and adolescence tracks into adulthood. However, limited longitudinal data exist on variation in tracking in relation to pediatric development periods, race, and gender. The study objective was to relate adult (age>30) weight status to that in childhood (3-11, mean 8.5 yrs; adult 36.6 yrs; N=4,511) and adolescence (12-17, mean 14 yrs; adult 39.9 yrs; N=7,215) from seven i3C cohorts. Overall tracking of BMI into adulthood was highly significant (p<0.0001) and similar from childhood and adolescence. Almost all obese children (74.3%) and adolescents (81.6%) became obese adults, and few obese children (6.5%) or adolescents (4.2%) became normal-weight adults. Overweight children and adolescents also were more likely to become obese adults (60.7% and 65.2%, respectively), and few became normal weight (11.7% and 6.6%). Normal weight children and adolescents tended to remain normal weight into adulthood (43% and 40.3%), but 22.7% of both normal-weight children and adolescents became obese. Patterns differed by race and gender (both p<0.001). Obese adolescent females had the highest persistence of obesity in adulthood (84.2%), followed by obese adolescent males (79.3%), obese male children (78.1%) and obese female children (70.6%). Normal weight male and female children and adolescents had a similar low prevalence of obesity as adults (22-23%), but females were more likely than males to remain normal weight from childhood (51.2% and 33.1%) and adolescence (48.7% and 30.6%). Tracking by race (see Table) showed that blacks had greater risk of adult obesity regardless of childhood or adolescent weight category. The results show that: 1) almost all obese and most overweight children and adolescents became obese adults; 2) one-fifth of white normal weight children and adolescents became obese adults; 3) even normal weight black children and adolescents are at significant risk of becoming obese adults. These data strongly suggest the need for early intervention to prevent adult obesity-related morbidity.

Background:Different movement efficiency in overweight children may affect accelerometer output data. The purpose was to investigate the ability of accelerometers to assess physical activity intensity and number of steps in normal-weight compared with overweight children.Methods:Eleven normal-weight and 14 overweight African American children walked at 2, 4, 5, and 6 km/h on a treadmill wearing Lifecorder, ActiGraph, RT3, and Biotrainer. Oxygen uptake was measured and steps manually counted. Fat free mass (FFM) was assessed from bioelectrical impedance analysis. Accelerometer counts and the individual linear regression lines of accelerometer counts versus VO2/FFM were evaluated, together with steps recorded by Lifecorder and Actigraph.Results:Correlations between accelerometer counts and VO2/FFM for all monitors were r ≥ .95 (P < .01). The accelerometer counts and their relationship to VO2/FFM did not generally differ significantly by body weight status. Lifecorder and Actigraph underestimated steps at 4, 5, and 6 km/h by less than 9%, but the error was up to −95% at 2 km/h.Conclusions:All 4 accelerometers show high ability to assess physical activity intensity, and can be used to compare physical activity between normal-weight and overweight children. The Lifecorder and the ActiGraph showed high accuracy in assessing steps, providing speed of movement exceeded 2 km/h.

The purpose of this study was to investigate gross and fine motor skill in overweight and obese children compared with normal-weight peers. According to international cut-off points for Body Mass Index (BMI) from Cole et al. (2000), all 117 participants (5–10 year) were classified as being normal-weight, overweight, or obese. Level of motor skill was assessed using the Movement Assessment Battery for Children (MABC). Scores for balance (p < .01) and ball skills (p < .05) were significantly better in normal-weight and overweight children as compared with their obese counterparts. A similar trend was found for manual dexterity (p < .10). This study demonstrates that general motor skill level is lower in obese children than in normal-weight and overweight peers.

Abstract Introduction Current practice for major pediatric burns includes fluid resuscitation using formulas that estimate fluid requirements based on weight and/or body surface area (BSA) along with percent total burn surface area (TBSA). Adult studies have shown that these formulas can cause fluid overload in obese patients and increase risk of complications. These findings have not been validated in pediatric patients. This study aims to evaluate whether a weight-based resuscitation formula increases the risk of complications in obese children following burn injuries and compares fluid estimates to those that incorporate BSA. Methods A retrospective review was conducted on 110 children (≤ 18 years old) admitted to an ABA-verified urban pediatric burn center from October 2008 to May 2020. Patients had ≥15% TBSA, were resuscitated with the weight-based Parkland formula, and had fluids titrated to urine output every two hours (1 ml/kg/hr if ≤ 30kg; 0.5 ml/kg/hr if > 30kg). Demographics, burn type, and TBSA were collected on admission. BSA-based Galveston and BSA-incorporated Cincinnati formula resuscitation predictions were also calculated. Output and input volumes were collected at 8h and 24h post-injury. Complications were collected throughout the hospital stay. Patients were classified into CDC-defined weight groups based on percentile ranges. Statistical analysis was conducted using SPSS Statistics version 10.0. Results This study included 11 underweight, 60 normal weight, 18 overweight, and 21 obese children. Our patients had a mean age-based weight CDC percentile of 62.2%, and mean TBSA of 25.4%. Predicted resuscitation volumes increased as CDC percentile increased for all three formulas (p=0.033, 0.092, 0.038), however there were no significant differences between overweight and obese children. Total fluid administered was higher as CDC percentile increased (p=0.023). However, overweight children received more total fluid than obese children. The difference between total fluids given and Galveston predicted resuscitation volumes were significant across all groups (p=0.042); however, the difference using the Parkland and Cincinnati formulas were not statistically significant. There were more children in the normal weight group who developed complications compared to other groups, but these findings were not significant. Conclusions The Parkland formula tended to underpredict fluid needs in the underweight, normal weight, and overweight children, and it overpredicted fluid needs for the obese. Further research is needed to determine the value of weight-based vs BSA-based or incorporated formulas in terms of their risk of complications.

Aims: To examine the association of weight status with the prevalence of blood pressure (BP), vital capacity, dental decay, and visual acuity among school-age children in Chengdu, China and to find the potential role of weight status to predict the common and frequently occurring diseases among school-age children. Methods: A cross-sectional study was conducted among 12,297 children aged 6-18 years from 10 schools in the Jinniu District of Chengdu, China. Body height, weight, waist circumference (WC), and BP were measured. Vital capacity, dental decay, and visual acuity were detected. Results: The overall prevalence of underweight, overweight, obesity, abdominal obesity, high BP, bad vital capacity weight index, dental decay, and low vision were 7.18, 13.47, 7.57, 18.90, 2.78, 21.93, 38.81, and 45.79%, respectively. After controlling for age, gender, and WC, it was found that overweight and obese children had a higher risk of developing high BP than normal weight children ([OR 4.20, p < 0.001] and [OR 8.76, p < 0.001], respectively), And adjusting for age, gender, and chest circumference, the risk of having bad vital capacity weight index among children with overweight and obesity was higher ([OR 2.15, p < 0.001] and [OR 5.40, p < 0.001], respectively), and the risk with underweight was lower (OR 0.35, p < 0.001). After eliminating the influential factors of gender and age, children who were underweight were 1.16 times (OR 1.16, p = 0.048) more likely to have caries than children with normal weight, but obese children were found to have a lower prevalence for dental cavities than children with normal weight (OR 0.79, p = 0.002). Underweight and obese children had a higher prevalence of low vision; the OR of the appearance of low vision was 1.21 (p = 0.016) for underweight children and 1.23 (p = 0.009) for obese children after adjusting the age and gender. Conclusions: Abnormal weight status among Chengdu urban school-age children was found to be a severe health problem, and it was strongly associated with BP, vital capacity, dental decay, and visual acuity.

Abstract The purpose of this study was to determine the relationship between peak cadence indicators and body mass index (BMI) and body fat percentage (BF%)-defined weight status in children. The sample comprised 485 Brazilian children. Minute-by-minute step data from accelerometry were rank ordered for each day to identify the peak 1-minute, 30-minute and 60-minute cadence values. Data were described by BMI–defined and bioelectrical impedance-determined BF% weight status. BMI-defined normal weight children had higher peak 1-minute (115.5 versus 110.6 and 106.6 steps/min), 30-minute (81.0 versus 77.5 and 74.0 steps/min) and 60-minute cadence (67.1 versus 63.4 and 60.7 steps/min) than overweight and obese children (p<.0001), respectively. Defined using %BF, normal weight children had higher peak 1-minute (114.5 versus 106.1 steps/min), 30-minute (80.4 versus 73.1 steps/min) and 60-minute cadence (66.5 versus 59.9 steps/min) than obese children (p<.0001). Similar relationships were observed in boys; however, only peak 1- minute cadence differed significantly across BMI and %BF-defined weight status categories in girls. Peak cadence indicators were negatively associated with BMI and BF% in these schoolchildren and significantly higher among normal weight compared to overweight or obese children.

Background: A relation between thyroid-stimulating hormone (TSH), insulin resistance – both of which are related to obesity – and thyroid volume has been suggested. Therefore, we analyzed thyroid volume and structure in relation to thyroid function parameters, weight status, and insulin resistance. Methods:This is a cross-sectional study in which weight status (BMI-SDS), thyroid function parameters (TSH, free tri-iodothyronine [fT3], and free thyroxine [fT4]), insulin resistance index (HOMA-IR), and thyroid volume (ultrasound) were determined in 617 overweight children (aged 10.4 ± 2.2 years, 50% male, BMI-SDS 2.5 ± 0.6) and in 27 normal-weight children of a similar age and gender. Furthermore, changes in thyroid volume and structure, and thyroid function parameters were analyzed in 83 obese children (51% male, mean age 10.3 ± 2.2) at baseline and at the end of a 1-year lifestyle intervention. Results: Overweight children had a significant greater thyroid volume (4.2 ± 1.8 vs. 4.1 ± 0.5 mL) and higher TSH (3.1 ± 1.5 vs. 2.4 ± 1.1 mU/L) and fT3 (4.4 ± 0.7 vs. 4.1 ± 0.5 pg/mL) concentrations compared to normal-weight children. In multiple linear regression analyses adjusted to multiple confounders, thyroid volume was significantly related to BMI-SDS (b coefficient 0.44 ± 0.10, r2 = 0.41) but not to any thyroid function parameter or HOMA-IR. Changes in BMI-SDS were significantly associated with changes in thyroid volume (r = 0.22). The changes in thyroid volume were not correlated to changes of any thyroid function parameter or HOMA-IR. Conclusions: Thyroid volume is positively correlated to weight status in childhood obesity and the change is reversible after weight loss independently of thyroid function parameters and insulin resistance. Further studies are needed to understand why thyroid volume is increased reversibly in overweight children.

ObjectivesTo investigate factors associated with movement behaviours among White British (WB) and South Asian (SA) children aged 6–8 years during school terms and holidays.DesignCross-sectional.SettingThree primary schools from the Bradford area, UK.ParticipantsOne hundred and sixty WB and SA children aged 6–8 years.Primary and secondary outcomesSedentary behaviour (SB), light physical activity (LPA) and moderate-to-vigorous physical activity (MVPA) measured by accelerometry during summer, winter and spring and during school terms and school holidays. Data were analysed using multivariate mixed-effects multilevel modelling with robust SEs. Factors of interest were ethnicity, holiday/term, sex, socioeconomic status (SES), weight status, weekend/weekday and season.ResultsOne hundred and eight children (67.5%) provided 1157 valid days of data. Fifty-nine per cent of children were WB (n=64) and 41% (n=44) were SA. Boys spent more time in MVPA (11 min/day, p=0.013) compared with girls and SA children spent more time in SB (39 min, p=0.017) compared with WB children in adjusted models. Children living in higher SES areas were more sedentary (43 min, p=0.006) than children living in low SES areas. Children were more active during summer (15 min MVPA, p<0.001; 27 LPA, p<0.001) and spring (15 min MVPA, p=0.005; 38 min LPA, p<0.001) and less sedentary (−42 min and −53 min, p<0.001) compared with winter. Less time (8 min, p=0.012) was spent in LPA during school terms compared with school holidays. Children spent more time in MVPA (5 min, p=0.036) during weekend compared with weekdays. Overweight and obese children spent more time in LPA (21 min, p=0.021) than normal-weight children.ConclusionThe results of our study suggest that significant child level factors associated with movement behaviours are ethnicity, sex, weight-status and area SES. Significant temporal factors are weekends, school holidays and seasonality. Interventions to support health enhancing movement behaviours may need to be tailored around these factors.

Abstract Objective Childhood obesity is a significant determinant of adult obesity. Among children born preterm, rapid “catch-up growth” in infancy increases the risk of later obesity. Parental perceptions of their child's weight status may compound the child's biologically heightened risk of obesity. Study Design We performed a secondary analysis of data on parental perceptions of child weight status from a randomized controlled trial (2012–2017, n = 331 toddlers born preterm). We used the Child Feeding Questionnaire (CFQ) to measure parental child feeding behaviors and beliefs. We calculated the prevalence of incorrect weight estimation, and used t-tests and chi-square tests to compare sample characteristics by correct versus incorrect weight estimation. We calculated odds ratios (ORs) for factors associated with parental underestimation of child weight status. Results Most (90%) children were of normal weight, whereas 3% were underweight and 7% were overweight. A majority (75%) of parents correctly estimated their child's weight status. Incorrect weight estimation was only associated with child's actual weight. Parents of overweight children were more likely to underestimate their child's weight status than parents of normal weight children (OR: 2.23, 95% confidence interval: 2.00–2.49). Mean CFQ scores differed by the child's actual weight status but not by the child's estimated weight status. Conclusion Among these toddlers born preterm, significantly higher proportions of parents with underweight and overweight children incorrectly estimated their child's weight status relative to parents of normal weight children. Our findings suggest that weight underestimation could be a problem in this population, although it was not associated with changes in feeding practices.
