Aim. To provide national estimates of obesity among US adults aged 20 years and older in 2011-2012 and track its trends from 1999 to 2012. Methods. Measured weight/height from National Health and Nutrition Examination Survey 1999–2012 waves was used to calculate body mass index (BMI) and prevalence measures. Piecewise logistic regressions were conducted to test the differential trends before and after 2010. Results. In 2011-2012, the age-adjusted prevalence of overweight and obesity combined (BMI≥25) was 71.1% (95% CI: 68.0%–74.2%) among men and 65.5% (61.8%–69.3%) among women, and the prevalence of obesity (BMI≥30) was 33.3% (30.5%–36.2%) among men and 35.8% (32.3%–39.4%) among women. From 1990–2000 to 2009-2010, the prevalence of overweight and obesity combined, obesity, grades 2 and 3 obesity combined (BMI≥35), and grade 3 obesity (BMI≥40) increased by 7.2%, 17.8%, 17.6%, and 33.0%, respectively. Compared to 2009-2010, most gender- and race/ethnicity-specific prevalence measures remained unchanged or slightly decreased in 2011-2012. No significant difference in trends among prevalence measures was found before and after 2010. Conclusions. Concurrent evidence on the leveling off of obesity in the US is thin. Given its high prevalence and profound socioeconomic consequences, close monitoring of the trend is warranted.

This study evaluated the effectiveness of a microcurrent toothbrush (approved by the US Food and Drug Administration [FDA]), which employs a superimposed alternating and direct electric current, named as a Proxywave® technology, similar to the intensity of the biocurrent, in plaque removal and reducing gingivitis by biofilm removal through the bioelectric effect. This study enrolled 40 volunteers with gingivitis. Dental observations were made every two weeks, before and after the use of each toothbrush. We randomly assigned participants into two groups: one group used the Proxywave® toothbrush (PB) for two weeks followed by the control toothbrush (CB) for two weeks, while the other group used the CB for two weeks followed by the PB. The participants had a two-week washout period. If the toothbrush used earlier has had an effect on the bacterial flora in the oral cavity, this is to remove this effect and return it to its previous state. During each dental visit, we recorded plaque index (PI) and gingival index (GI) scores. The PI and GI scores were significantly lower in both the PB and the CB (p < 0.05). Considering the PI, there was no significant difference between the toothbrushes on all the surfaces. Considering the GI, the PB showed a significant decrease in the interproximal surface, compared to the CB (p < 0.05). The PB showed a significant decrease in the interproximal GI and had a beneficial effect in the interproximal area where the bristles could not reach. No adverse events were observed in the participants during the clinical trial. The microcurrent toothbrush is a device that can be safely used for plaque removal.

This study examined temporal trends in body mass index (BMI) among United States adults with intellectual disability (ID) participating in Special Olympics from 2005 to 2010. In addition, the prevalence of obesity was compared with published National Health and Nutrition Examination Survey (NHANES) statistics. After data cleaning, 6,004 height and weight records (male = 57%) were available from the Special Olympics International Healthy Athletes Health Promotion database for the calculation of BMI. Rates of overweight and obesity were very high but generally stable over time. Compared with NHANES statistics, the prevalence of obesity was significantly higher for Special Olympics female participants in each data collection cycle. Integrated efforts to understand the social, environmental, behavioral, and biological determinants of obesity and among Special Olympics participants are needed.

Abstract Objective: To estimate the prevalence of thinness, overweight and obesity among Tibetan adolescents aged 12-17 years. Design: Cross-sectional survey. Setting: Shigatse city of Tibet municipality, with an average altitude of more than 4000 m. Subjects: Study participants included 2,642 adolescents aged 12-17 years selected from 6 schools using a convenient cluster sampling method. Results: The prevalence of thinness/overweight/obesity among Tibetan adolescents was 9.4%/5.4%/1.4% (China definition), 14.7%/4.4%/0.7% (IOTF definition), and 2.8%/5.7%/0.9% (WHO definition). The prevalence of thinness and overweight was significantly different between both sexes based on each of three BMI classification criteria (P <0.001). There was no significant difference in the prevalence of obesity between both sexes according to each of three BMI criteria. There was no clear trend in the prevalence of thinness across ages according to the China or IOTF definition (both P >0.05), whereas an upward trend was observed for thinness in boys according to the IOTF definition (P for trend <0.05). In contrast, the prevalence of thinness tended to decrease with increasing age in girls according to the IOTF definition, and in total sample according to the WHO definition (P for trend <0.05). Conclusions: Among Tibetan adolescents, the prevalence of overweight and obesity is relatively low, while the prevalence of thinness is high, especially in boys. These data suggest urgent attention is needed to control adolescent thinness in Tibet.

Splenic injuries are mostly treated with nonoperative management (NOM) with observation to monitor for continued hemorrhage and holding early chemical DVT prophylaxis to reduce the risk of NOM failure. Eberle et al demonstrated chemoprophylaxis prior to 72 hours didn’t increase failure rate of NOM. We chose to extrapolate this finding and compare outcomes in high-grade splenic injuries (HGSI) with chemoprophylaxis before and after 48 hours. From January 2013 to December 2017, 104 patients with HGSI received chemoprophylaxis with unfractionated heparin (UH) or low molecular weight heparin (LMWH) within 72 hours of diagnosis. Of these, 8 patients received chemoprophylaxis within 24 hours, 46 between 24 and 48 hours, and 50 patients between 48 and 72 hours. This population consisted of 70 males and 34 females, with an average age of 40.1 years. The average ISS was 23 and the majority (77%) were grade 3 injuries. We observed 6 failures of NOM: 1 in the <24 hour group, 3 in the 24-48 hour group, and 2 in the 48-72 hour group. There was no statistically significant difference between the <24 hour and >24 groups or between the <48 hour and 48-72 hour groups. A linear regression analysis created a model describing the time to initiation of DVT prophylaxis using age, sex, splenic injury grade, and ISS; the failure rate decreased by 0.00002% for each hour prior to giving DVT prophylaxis, with a P value of .111. We conclude a noninferiority statement that DVT prophylaxis prior to 48 hours does not increase the risk of NOM failure.

Abstract Objectives: This study aimed to examine age-specific trends in the prevalence of overweight and obesity in schoolchildren in Kuwait over a 13-year period (2007 to 2019) using the World Health Organization (WHO), the Centers for Disease Control and Prevention (CDC) and the International Obesity Taskforce (IOTF) definitions. Design: Using cross-sectional approach, Kuwait Nutrition Surveillance System (KNSS) objectively measured weight and height of schoolchildren over a 13-year period. Log-binomial regression models were used to examine age-specific trends of obesity and overweight over the study period. Setting: Public primary, middle, and high schools in all provinces of Kuwait. Participants: Schoolchildren aged 5-19 years (N 172 603) Results: According to the WHO definition, the prevalence of overweight and obesity in schoolchildren respectively increased from 17.73% and 21.37% in 2007 to 20.19% and 28.39% in 2019 (P for trends<0.001). There is evidence that the obesity in females (but not males) has levelled off in the period 2014-2019 according to the three definitions of obesity, which is corroborated by a similar trend in the mean of BMI-for-age Z score. Conclusion: The prevalence of obesity and overweight in schoolchildren in Kuwait has risen over the last 13 years and trends are similar across all definitions. Obesity is no longer increasing at the same pace and there is evidence that the prevalence of obesity in females has plateaued. The current level of childhood overweight and obesity is too high and requires community-based and school-based interventions.

We investigated the impact of the Kids’ Shop Smart® Tour program on participants’ attitudes toward trying new foods and eating a variety of foods, as well as their recognition of Canada’s Food Guide to Healthy Eating. Data were collected from parents/ caregivers, students in kindergarten to grade 3, and teachers; questionnaires, quizzes, and interviews were used. Questionnaires were sent home with 947 students; 52% of parents/caregivers returned completed questionnaires. Many parents/caregivers reported that their children tried and liked unfamiliar foods on the tour. No significant difference was detected in children’s willingness to try new foods or consumption of a greater variety of food before and after the tour. Quiz score differences between participants and a comparison group were not statistically significant. Of the 38 teachers who completed interviews, 97% reported that the program helped them meet curriculum requirements; 95% would recommend the resource to other teachers. Quantitative findings do not indicate that the program increases children’s willingness to try new foods or eat a greater variety of food. However, qualitative data revealed that some parents observed their children trying new foods more willingly and demonstrating greater knowledge of and interest in Canada’s Food Guide to Healthy Eating. Further research with validated measurement tools is recommended to establish the effectiveness of the Kids’ Shop Smart® Tour.

AbstractObjectiveThe present study evaluated the contribution of 100 % orange juice (OJ) consumption to the intakes of macronutrients and energy and its impact on body composition.DesignA cross-sectional study was conducted. The main exposure was OJ consumption based on two non-consecutive 24 h diet recalls. Macronutrient and energy intakes and body composition parameters were outcome measures. All statistical analyses were carried out using SAS and SUDAAN statistical software packages to allow for multistage sample designs.SettingThe US population and its subgroups.SubjectsThe US population aged ≥4 years (n 13 971) from the National Health and Nutrition Examination Survey 2003–2006, conducted by the National Center for Health Statistics.ResultsIn this US population, OJ consumers had lower BMI and healthier lifestyle behaviours (including lower alcohol consumption and smoking as well as higher exercise level) than non-consumers (P < 0·05). After adjusting for covariates, OJ consumers had higher daily intakes of carbohydrate, total sugar, total fat and energy than non-consumers (P < 0·01). However, these linear trends still remained even after OJ was removed from the food list of items consumed. Adult OJ consumers had lower BMI, waist circumference and percentage body fat than non-consumers (P < 0·01), as well as lower odds ratio for overweight and obesity (P < 0·01). These effects were not seen in children and adolescents, where there was no significant difference in BMI, waist circumference and percentage body fat in OJ consumers compared with non-consumers.ConclusionsOJ consumption was associated with healthier body composition in adults; while there were no significant associations between OJ consumption and body composition in children and adolescents.

Abstract Background We intend to explore whether sleep duration is associated with overweight and obesity among the adult American population. Furthermore, we stratified the study population by age and sex in the subgroup analysis to investigate the potential disparities between adults and older adults, and men and women. Methods In total, 2459 individuals from the 2015–2016 National Health and Nutrition Examination Survey cycle were included for analysis in this study. Sleep duration was assessed by the Sleep Disorders Questionnaire. Classification of the short-sleep, normal-sleep, and long-sleep group was based on the recommendation of the National Sleep Foundation. Bodyweight was measured during the physical examination. Multivariate logistic regression models were implemented. Results We observed a significantly higher overweight incidence in the short-sleep group compared to the normal-sleep group (OR = 1.825, 95%CI: 1.251–2.661, P = 0.004). Short-sleep (OR = 1.832, 95%CI: 1.215–2.762, P = 0.007) duration and long-sleep duration (OR = 1.370, 95%CI: 1.043–1.800, P = 0.027) were associated with higher prevalence of obesity. When stratified by age, short-sleep also increased the overweight and obese incidence 1.951 and 1.475 times in the adult group. In the sex-stratified subgroup analysis, the short-sleep group showed 2.49 times higher overweight incidence among females. The prevalence of obesity was 2.59 times higher in the short-sleep group and 1.698 times higher in the long-sleep group in the female population. Conclusions Sleep duration is associated with the occurrence of overweight and obesity, with sleep duration less than 7 h increase the overweight and obesity rate nearly 2 folds comparing to sleep 7–9 h.

AbstractObjective:To determine the prevalence of overweight and obesity in British young people (4–18 years) in 1997.Design:Cross-sectional analysis of the National Diet and Nutrition Survey of young people.Setting:Great Britain.Subjects:Nationally representative sample of 1836 young people (age 4–18 years).Results:The prevalence of obesity based on body mass index (weight/height2) and the International Obesity Task Force cut–offs was 4.0%, with a further 15.4% identified as overweight. Asians were almost four times as likely to be obese as white subjects (13.6 vs. 3.5%, P < 0.001). Among white subjects there was no significant difference in the prevalence of obesity between girls and boys, or with age. The risk of obesity was significantly higher in subjects from social classes IV and V than from social classes I–III (6.5 vs. 2.7%, P = 0.003). Subjects living in Scotland and Wales were significantly more likely to be obese than those in England (7.6 and 6.5 vs. 2.9%, respectively, P < 0.01). Multiple logistic regression showed that, among white subjects, those in social classes IV and V living in Wales and Scotland were three times more likely to be obese than the other children in the survey (odds ratio 3.3, 95% confidence interval 1.1–9.8).Conclusion:These data provide information on the national prevalence of overweight and obesity in Great Britain and baseline data from which to monitor future trends. This analysis provides important demographic information on those most at risk of obesity, which may be used to inform public health strategies to prevent obesity in young people.

Introduction: The proportion of US adults with hypertension who had controlled blood pressure (BP) decreased from 2013-2018. The rising prevalence of obesity has been implicated as a reason for this decline. We investigated trends in BP control from 2013-2018 among US adults with hypertension, overall and among those taking antihypertensive medication, by body mass index (BMI) category. Methods: We used National Health and Nutrition Examination Survey data from 2013-2014, 2015-2016, and 2017-2018 for US adults aged ≥18 with hypertension (N=5,580). We examined the BMI distribution [normal (BMI <25 kg/m 2 ), overweight (BMI 25-<30 kg/m 2 ), class 1 obesity (BMI 30-<35 kg/m 2 ), class 2 or 3 obesity (BMI ≥35 kg/m 2 )] in each survey cycle. We calculated the age-adjusted prevalence of BP control (<140/90 mmHg) overall and among those taking antihypertensive medication in each survey cycle by BMI category. We examined trends in BP control within BMI category adjusted for age and other sociodemographic and clinical characteristics; we tested differences in trends by BMI category using interaction terms. Results: The prevalence of overweight and obesity among US adults with hypertension did not change from 2013-2018 ( Table ). The overall proportion of adults with hypertension who had controlled BP was higher among those with overweight or obesity than those with normal BMI. BP control among those taking antihypertensive medication was similar among those with overweight or obesity and those with normal BMI. BP control overall decreased over time with no evidence of a difference by BMI category. Among those taking antihypertensive medication, BP control decreased in those who were overweight or had class 1 obesity but not in those with normal BMI or class 2 or 3 obesity. Conclusions: Among US adults with hypertension, there was no increase in the prevalence of overweight and obesity from 2013-2018 and BP control decreased in all subgroups. These findings suggest the obesity epidemic is not driving the decrease in BP control in the US population.
