ABSTRACT: Objectives
To provide updated prevalence data on obesity trends among US children and adolescents aged 2 to 19 years from a nationally representative sample.Methods
We used the NHANES for years 1999 to 2016. Weight status was determined by using measured height and weight from the physical examination component of the NHANES to calculate age- and sex-specific BMI. We report the prevalence estimates of overweight and obesity (class I, class II, and class III) by 2-year NHANES cycles and compared cycles by using adjusted Wald tests and linear trends by using ordinary least squares regression.Results
White and Asian American children have significantly lower rates of obesity than African American children, Hispanic children, or children of other races. We report a positive linear trend for all definitions of overweight and obesity among children 2-19 years old, most prominently among adolescents. Children aged 2 to 5 years showed a sharp increase in obesity prevalence from 2015 to 2016 compared with the previous cycle.Conclusions
Despite previous reports that obesity in children and adolescents has remained stable or decreased in recent years, we found no evidence of a decline in obesity prevalence at any age. In contrast, we report a significant increase in severe obesity among children aged 2 to 5 years since the 2013-2014 cycle, a trend that continued upward for many subgroups.

Project description:ImportanceStudies of trends in excess weight among European children throughout the last few decades have rendered mixed results. Additionally, some studies were outdated, were based on self-reported weight and height, or included only a few European countries.ObjectiveTo assess prevalence trends in measured overweight and obesity among children across Europe from 1999 to 2016 using a systematic methodology.Data sourcesMEDLINE, Embase, CINAHL, and Web of Science were searched from their inception until May 2018. Moreover, searches were conducted on health institutions' websites to identify studies not published in scientific journals.Study selectionThe inclusion criteria were: (1) studies reporting the population-based prevalence of excess weight (overweight plus obesity) or obesity according to body mass index cutoffs proposed by the International Obesity Task Force; (2) cross-sectional or follow-up studies; and (3) studies including populations aged 2 to 13 years.Data extraction and synthesisLiterature review and data extraction followed established guidelines. The Mantel-Haenszel method was used to compute the pooled prevalence estimates and their 95% CI whenever there was no evidence of heterogeneity (I2 < 50%); otherwise, the DerSimonian and Laird random-effects method was used. Subgroup analyses by study year, country, or European region (Atlantic, Iberian, Central, and Mediterranean) were conducted. Prevalence estimates were calculated as an aggregate mean, weighted by the sample size and the number of individuals in each study.ResultsA total of 103 studies (477 620 children aged 2 to 13 years) with data from 28 countries were included. The combined prevalence of overweight and obesity in the Iberian region tended to decrease from 30.3% (95% CI, 28.3%-32.3%) to 25.6% (95% CI, 19.7%-31.4%) but tended to increase in the Mediterranean region from 22.9% (95% CI, 17.9%-27.9%) to 25.0% (95% CI, 14.5%-35.5%). No substantial changes were observed in Atlantic Europe or Central Europe, where the overweight and obesity prevalence changed from 18.3% (95% CI, 14.0%-23.9%) to 19.3% (95% CI, 17.7%-20.9%) and from 15.8% (95% CI, 13.4%-18.5%) to 15.3% (95% CI, 11.6%-20.3%), respectively.Conclusions and relevanceThe prevalence of childhood overweight and obesity is very high, but trends have stabilized in most European countries. There are substantial between-country differences in the current levels and trends of overweight and obesity. The rising prevalence in some Mediterranean countries is worrisome.Trial registrationPROSPERO identifier: CRD42017056924.

Project description:ObjectiveThe aim of this study was to compare national estimates of self-reported and measured height and weight, BMI, and obesity prevalence among adults from US surveys.MethodsSelf-reported height and weight data came from the National Health and Nutrition Examination Survey (NHANES), the National Health Interview Survey, and the Behavioral Risk Factor Surveillance System for the years 1999 to 2016. Measured height and weight data were available from NHANES. BMI was calculated from height and weight; obesity was defined as BMI ≥ 30.ResultsIn all three surveys, mean self-reported height was higher than mean measured height in NHANES for both men and women. Mean BMI from self-reported data was lower than mean BMI from measured data across all surveys. For women, mean self-reported weight, BMI, and obesity prevalence in the National Health Interview Survey and Behavioral Risk Factor Surveillance System were lower than self-report in NHANES. The distribution of BMI was narrower for self-reported than for measured data, leading to lower estimates of obesity prevalence.ConclusionsSelf-reported height, weight, BMI, and obesity prevalence were not identical across the three surveys, particularly for women. Patterns of misreporting of height and weight and their effects on BMI and obesity prevalence are complex.

Project description:ContextThe prevalence of childhood obesity increased in the 1980s and 1990s but there were no significant changes in prevalence between 1999-2000 and 2007-2008 in the United States.ObjectivesTo present the most recent estimates of obesity prevalence in US children and adolescents for 2009-2010 and to investigate trends in obesity prevalence and body mass index (BMI) among children and adolescents between 1999-2000 and 2009-2010.Design, setting, and participantsCross-sectional analyses of a representative sample (N = 4111) of the US child and adolescent population (birth through 19 years of age) with measured heights and weights from the National Health and Nutrition Examination Survey 2009-2010.Main outcome measuresPrevalence of high weight-for-recumbent length (≥95th percentile on the growth charts) among infants and toddlers from birth to 2 years of age and obesity (BMI ≥95th percentile of the BMI-for-age growth charts) among children and adolescents aged 2 through 19 years. Analyses of trends in obesity by sex and race/ethnicity, and analyses of trends in BMI within sex-specific age groups for 6 survey periods (1999-2000, 2001-2002, 2003-2004, 2005-2006, 2007-2008, and 2009-2010) over 12 years.ResultsIn 2009-2010, 9.7% (95% CI, 7.6%-12.3%) of infants and toddlers had a high weight-for-recumbent length and 16.9% (95% CI, 15.4%-18.4%) of children and adolescents from 2 through 19 years of age were obese. There was no difference in obesity prevalence among males (P = .62) or females (P = .65) between 2007-2008 and 2009-2010. However, trend analyses over a 12-year period indicated a significant increase in obesity prevalence between 1999-2000 and 2009-2010 in males aged 2 through 19 years (odds ratio, 1.05; 95% CI, 1.01-1.10) but not in females (odds ratio, 1.02; 95% CI, 0.98-1.07) per 2-year survey cycle. There was a significant increase in BMI among adolescent males aged 12 through 19 years (P = .04) but not among any other age group or among females.ConclusionIn 2009-2010, the prevalence of obesity in children and adolescents was 16.9%; this was not changed compared with 2007-2008.

Project description:ImportanceDifferences in childhood obesity by demographics and urbanization have been reported.ObjectiveTo present data on obesity and severe obesity among US youth by demographics and urbanization and to investigate trends by urbanization.Design, setting, and participantsMeasured weight and height among youth aged 2 to 19 years in the 2001-2016 National Health and Nutrition Examination Surveys, which are serial, cross-sectional, nationally representative surveys of the civilian, noninstitutionalized population.ExposuresSex, age, race and Hispanic origin, education of household head, and urbanization, as assessed by metropolitan statistical areas (MSAs; large: ≥ 1 million population).Main outcomes and measuresPrevalence of obesity (body mass index [BMI] ≥95th percentile of US Centers for Disease Control and Prevention [CDC] growth charts) and severe obesity (BMI ≥120% of 95th percentile) by subgroups in 2013-2016 and trends by urbanization between 2001-2004 and 2013-2016.ResultsComplete data on weight, height, and urbanization were available for 6863 children and adolescents (mean age, 11 years; female, 49%). In 2013-2016, the prevalence among youth aged 2 to 19 years was 17.8% (95% CI, 16.1%-19.6%) for obesity and 5.8% (95% CI, 4.8%-6.9%) for severe obesity. Prevalence of obesity in large MSAs (17.1% [95% CI, 14.9%-19.5%]), medium or small MSAs (17.2% [95% CI, 14.5%-20.2%]) and non-MSAs (21.7% [95% CI, 16.1%-28.1%]) were not significantly different from each other (range of pairwise comparisons P = .09-.96). Severe obesity was significantly higher in non-MSAs (9.4% [95% CI, 5.7%-14.4%]) compared with large MSAs (5.1% [95% CI, 4.1%-6.2%]; P = .02). In adjusted analyses, obesity and severe obesity significantly increased with greater age and lower education of household head, and severe obesity increased with lower level of urbanization. Compared with non-Hispanic white youth, obesity and severe obesity prevalence were significantly higher among non-Hispanic black and Hispanic youth. Severe obesity, but not obesity, was significantly lower among non-Hispanic Asian youth than among non-Hispanic white youth. There were no significant linear or quadratic trends in obesity or severe obesity prevalence from 2001-2004 to 2013-2016 for any urbanization category (P range = .07-.83).Conclusions and relevanceIn 2013-2016, there were differences in the prevalence of obesity and severe obesity by age, race and Hispanic origin, and household education, and severe obesity was inversely associated with urbanization. Demographics were not related to the urbanization findings.

Project description:ImportanceThe World Health Assembly has called for the elimination of hepatitis B and C by 2030. As hepatitis B has no cure, the US strategy to eliminate hepatitis B has focused on prevention through vaccination. However, there are limited data on the trend in vaccine-associated immunity since the US implementation of universal infant hepatitis B vaccination.ObjectiveTo compare self-reported hepatitis B vaccination coverage among children and adolescents with serologic evidence of immunity and infection in the US from 1999 to 2016.Design, setting, and participantsThis population-based cross-sectional study used data from the National Health and Nutrition Examination Survey (NHANES) from 1999 to 2016. US-born persons aged 2 to 18 years without missing hepatitis B serologic test results and with reported vaccination history were included. Data were analyzed from September 2017 to June 2018.Main outcomes and measuresThe proportion of participants who reported complete vaccination for hepatitis B and who had positive serologic test results indicating immunity.ResultsOf 21 873 children and adolescents, 51.2%% were male, and the mean (SD) age was 10.6 (4.6) years. The survey reported that hepatitis B vaccination coverage increased significantly from 1999 to 2016 (from 62.6% [95% CI, 58.6%-66.4%] to 86.3% [95% CI, 82.9%-89.2%]; P < .001). Vaccine-associated immunity also increased from 1999 to 2016 among children aged 2 to 5 years (from 60.7% [95% CI, 48.8%-71.4%] to 65.2% [95% CI, 57.4%-72.3%]; P = .001) but decreased among children aged 6 to 10 years (from 64.6% [95% CI, 57.7%-70.9%] to 46.5% [95% CI, 39.1%-54.0%]; P < .001), adolescents aged 11 to 13 years (from 68.8% [95% CI, 58.1%-77.8%] to 26.2% [95% CI, 18.6%-35.5%]; P < .001), and adolescents aged 14 to 18 years (from 68.5% [95% CI, 62.9%-73.6%] to 15.6% [95% CI, 12.2%-19.8%]; P < .001). By birth year, serologic evidence of vaccine-associated immunity significantly decreased in the 1994-2003 NHANES birth cohort but not among those born between 1988 and 1993. Non-US-born children and adolescents did not show the same decreasing trend in immunity.Conclusions and relevanceIn this cross-sectional study, decreasing hepatitis B immunity was observed among US-born children and adolescents in the 1994-2003 NHANES birth cohort despite increasing rates of hepatitis B vaccination coverage. These findings suggest a possible need for surveillance and a booster vaccine dose for hepatitis B as those without serologic evidence of immunity become young adults and may engage in behaviors associated with an increased risk for infection.

Project description:ImportanceImproved understanding of trends in the proportion of individuals with metabolically healthy obesity (MHO) may facilitate stratification and management of obesity and inform policy efforts.ObjectivesTo characterize trends in the prevalence of MHO among US adults with obesity, overall and by sociodemographic subgroups.Design, setting, and participantsThis survey study included 20 430 adult participants from 10 National Health and Nutrition Examination Survey (NHANES) cycles between 1999-2000 and 2017-2018. The NHANES is a series of cross-sectional and nationally representative surveys of the US population conducted continuously in 2-year cycles. Data were analyzed from November 2021 to August 2022.ExposuresNational Health and Nutrition Examination Survey cycles from 1999-2000 to 2017-2018.Main outcomes and measuresMetabolically healthy obesity was defined as a body mass index of 30.0 (calculated as weight in kilograms divided by height in meters squared) without any metabolic disorders in blood pressure, fasting plasma glucose (FPG), high-density lipoprotein cholesterol (HDL-C), or triglycerides based on established cutoffs. Trends in the age-standardized prevalence of MHO were estimated using logistic regression analysis.ResultsThis study included 20 430 participants. Their weighted mean (SE) age was 47.1 (0.2) years; 50.8% were women, and 68.8% self-reported their race and ethnicity as non-Hispanic White. The age-standardized prevalence (95% CI) of MHO increased from 3.2% (2.6%-3.8%) in the 1999-2002 cycles to 6.6% (5.3%-7.9%) in the 2015-2018 cycles (P < .001 for trend). There were 7386 adults with obesity. Their weighted mean (SE) age was 48.0 (0.3) years, and 53.5% were women. The age-standardized proportion (95% CI) of MHO among these 7386 adults increased from 10.6% (8.8%-12.5%) in the 1999-2002 cycles to 15.0% (12.4%-17.6%) in the 2015-2018 cycles (P = .02 for trend). Substantial increases in the proportion of MHO were observed for adults aged 60 years or older, men, non-Hispanic White individuals, and those with higher income, private insurance, or class I obesity. In addition, there were significant decreases in the age-standardized prevalence (95% CI) of elevated triglycerides (from 44.9% [40.9%-48.9%] to 29.0% [25.7%-32.4%]; P < .001 for trend) and reduced HDL-C (from 51.1% [47.6%-54.6%] to 39.6% [36.3%-43.0%]; P = .006 for trend). There was also a significant increase in elevated FPG (from 49.7% [95% CI, 46.3%-53.0%] to 58.0% [54.8%-61.3%]; P < .001 for trend) but no significant change in elevated blood pressure (from 57.3% [53.9%-60.7%] to 54.0% [50.9%-57.1%]; P = .28 for trend).Conclusions and relevanceThe findings of this cross-sectional study suggest that the age-standardized proportion of MHO increased among US adults from 1999 to 2018, but differences in trends existed across sociodemographic subgroups. Effective strategies are needed to improve metabolic health status and prevent obesity-related complications in adults with obesity.

Project description:The number of hospitalizations with an obesity diagnosis have increased among youth in the past two decades, yet remain understudied, particularly among racial/ethnic minority groups. The purpose of this study was to characterize obesity prevalence among children, adolescents, and young adults receiving inpatient care in Hawai'i acute care hospitals during 2015-2016. This study analyzed statewide administrative data from a racially and ethnically diverse population. Participants (N = 7,751) included Hawai'i residents aged 5-29 years receiving inpatient care, excluding those hospitalized due to pregnancy. Recorded height and weight were used to calculate body mass index (BMI) and classify obesity. Primary or secondary diagnoses for obesity were assessed. A multivariable logistic regression model was used to determine characteristics associated with obesity, including race/ethnicity-sex interaction, age group, insurance payer, and county of residence. Based on BMI, 28.4% (2,202/7,751) of patients had obesity. However, an obesity diagnosis was present only in 40.4% (889/2,202) of patients with obesity based on BMI (11.9% of all patients). In the multivariable model, compared to whites, the odds of having obesity were highest among Pacific Islanders [adjusted odds ratio (aOR) = 4.07, 95% CI(3.16-5.23)] and Native Hawaiians [aOR = 2.16, 95% CI(1.75-2.67)] for females, and among Pacific Islanders [aOR = 5.39, 95% CI(4.27-6.81)], Native Hawaiians [aOR = 2.36, 95% CI(1.91-2.91)], and Filipinos [aOR = 2.08, 95% CI(1.64-2.64)] for males. Obesity was also associated with age group, but not insurance payer type or county of residence. These findings support the need for greater attention to obesity in the inpatient setting and equity-focused interventions to reduce obesity among younger hospitalized patients.

Project description:ObjectivesTo describe the temporal development of mortality and health service utilisation defined as in- and outpatient hospital contacts, contacts with general practitioner and specialists, and prescribed dispensed medication among Danish children 0-5 years of age from 1999 to 2016.DesignRegister-based descriptive study.ParticipantsAll children born in Denmark in the period 1994-2016 followed until 5 years of age.Main outcome measuresAnnual incidence rates of mortality and health service utilisation outcomes, and incidence rate ratios compared to the reference calendar year 1999. The new measure of post-discharge mortality is presented.ResultsPost-discharge mortality decreased from 1999 to 2016, IRR2016 = 0.49 (95% CI: 0.36 to 0.66). Total contacts did not change much over time, IRR2016 = 1.02 (1.02 to 1.03), but increased among neonates, IRR2016 = 3.69 (3.63 to 3.75), and decreased among children with chronic disease IRR2016 = 0.94 (0.93 to 0.94). In- and out-patient hospitalisations increased, IRR2016 = 1.26 (1.24-1.27) resp. IRR2016 = 1.62 (1.60-1.63), contacts with medical specialists increased, IRR2016 = 1.43 (1.42 to 1.43), whilst contacts with general practitioner decreased, IRR2016 = 0.91 (0.91 to 0.91). Medication use decreased, IRR2016 = 0.82 (0.82 to 0.82).ConclusionsOur measure of post-discharge mortality was halved during the study period indicating improved health. Overall health service utilisation did not change much, but the type of utilisation changed, and the development over time differed between subgroups defined by age and chronic disease status. Our findings call for considerations about the benefit of increased specialisation and increased use of health services among 'healthy' children not suffering from chronic disease.

Project description:IntroductionObesity is a public health crisis in the USA. This study aimed to estimate the prevalence of obesity and severe obesity in US children and adolescents and identify novel targetable risk factors associated with childhood obesity.MethodsFrom the US National Health and Nutrition Examination Survey from 1999 to 2018, 35,907 children aged 2-19 with body mass index (BMI) data were included. Obesity and severe obesity were defined as BMI ≥95th percentile and ≥120% of 95th percentile of US Centers for Disease Control and Prevention growth charts, respectively. Trends in the prevalence of obesity and subgroup analyses according to socioeconomic factors and language used in the interview were analyzed.ResultsThe prevalence of obesity and severe obesity increased from 14.7 [95% confidence interval: 12.9-17.0]% to 19.2 [17.2-21.0]% and 3.9 [2.9-5.0]% to 6.1 [4.8-8.0]% in 1999-2018, respectively (p = 0.001 and p = 0.014, respectively). In 2017-2018, the prevalence of obesity among children from Spanish-speaking households was 24.4 [22.4-27.0]%, higher than children from English-speaking households (p = 0.027).ConclusionThe prevalence of childhood obesity kept increasing in 1999-2018. The problem is worse in children from Spanish-speaking households. Novel and targeted public health intervention strategies are urgently warranted to effectively halt the rising epidemic of childhood obesity.

Project description:ImportanceObesity rates have risen in the United States since the 1980s. Several studies have shown links between obesity and the incidence of specific cancer types, but none have systematically examined obesity prevalence at the time of cancer diagnosis, or among clinical trial participants, all of which may affect clinical outcomes.ObjectiveTo examine the prevalence of obesity and, separately, overweight and obesity over 30 years among patients with cancer enrolled in clinical treatment trials for obesity-related cancers; and to compare trends with corresponding trends in the US.Design, setting, and participantsThis cohort study examined clinical treatment trials for obesity-related cancers conducted by the SWOG Cancer Research Network at community and academic sites. Participants included adult patients enrolled in phase 2 or phase 3 clinical treatment trials in obesity-related cancers between 1986 and 2016. Statistical analysis was performed from June 2020 to July 2022.ExposuresYear of enrollment to a clinical trial.Main outcomes and measuresPrevalence of obesity (body mass index [BMI] ≥ 30) and overweight or obesity (BMI > 25) at the time of clinical trial enrollment. Multivariable logistic regression analysis, adjusted for demographic and clinical factors, was used to analyze patient height and weight collected at clinical trial enrollment.ResultsAmong 23 926 patients (median [IQR] age, 58 [51-66] years; 17 594 [73.5%] female; 969 [4.0%] Hispanic, 2173 [9.1%] non-Hispanic Black, 19 890 [83.1%] non-Hispanic White) enrolled between 1986 and 2016, unadjusted obesity rates increased from 23.5% (in 1986 to 1990 [n = 657]) to 42.3% (in 2011 to 2016 [n = 836]). There was an increasing linear trend in obesity (odds ratio [OR], 1.23 for each 5-year increase; 95% CI, 1.21-1.26; P < .001), which persisted after covariate adjustment for demographic and clinical characteristics. Findings were consistent for the combined prevalence of overweight and obesity. The observed overall increasing trend in obesity prevalence from 1999-2000 to 2015-2016 was greater in trial patients (21.3% [SE = 0.7] to 49.1% [SE = 1.6]) than in US adults (30.5% [SE = 1.5] to 39.6% [SE = 1.6]) (P for trend = .03), but was similar to US cancer survivors (18.9% [SE = 1.9] to 42.2% [SE = 2.1]; P for trend = .31).Conclusions and relevanceThis cohort study found that patients with cancer and obesity are currently well-represented in cancer clinical trials, increasing confidence that trial findings are generalizable to patients with obesity in clinical practice. Availability of data on height and weight at diagnosis through cancer registries will enable a more rigorous analysis of obesity prevalence among patients with cancer.
