Body mass index in primary and secondary pediatric hypertension.

The objectives of this study were (1) to determine the relationship of body mass index (BMI) to primary or secondary hypertension in children and adolescents and (2) to assess BMI at the age of onset of hypertension in children and adolescents. Patient demographics, BMI, family history, presentation of disease, etiology of hypertension, medication, laboratory data, and findings from other procedures were recorded for all patients with hypertension followed in the Pediatric Nephrology Clinic at Children's Hospital, Columbus, Ohio, over a 4-year period. In total, 314 patients were studied: 218 w…

Breastfeeding, body mass index, asthma and atopy in children.

The objective of this study was to determine the relationship between breastfeeding, asthma and atopy, and any influence of child body mass index (BMI). Prospective birth cohort data were used to model the association between breastfeeding duration, BMI, asthma and atopy in children at six years. After adjustment for BMI and associated covariates, breastfeeding (per additional month of feeding) was marginally associated with decreased BMI (p=0.083). BMI was significantly associated with current asthma (p=<0.0005) and atopy (p=0.055). Exclusive breastfeeding for less than four months was a risk…

Maternal smoking, body mass index, and neural tube defects.

The Swedish health registries were used to investigate a possible effect on the incidence of neural tube defects (NTDs) of maternal smoking and maternal body mass index (BMI) (kg/m2). Among 1,199,701 infants born in 1983-1993 with known smoking exposure in early pregnancy, 621 infants with NTDs were selected. After controlling for year of birth, maternal age, parity, education level, BMI, and immigrant status (yes/no), a highly significant, protective effect of maternal smoking on the incidence of NTDs was found. The adjusted odds ratios (OR) and (95% confidence intervals (CI)) for maternal sm…

Comparisons between inverted body mass index and body mass index as proxies for body fatness and risk factors for metabolic risk and cardiorespiratory fitness in Portuguese adolescents.

OBJECTIVES: To compare inverted body mass index (iBMI, cm(2) /kg) and body mass index (BMI, kg/m(2) ) as predictors of body fatness, metabolic risk, and cardiovascular fitness in adolescents. METHODS: A cross-sectional school-based study was conducted on 445 Portuguese adolescents (252 girls and 193 boys) aged 10-17 years. Height and body mass were assessed to determine iBMI and BMI, percent body fatness was determined from skinfold measures (tricep, subscapular) using the Slaughter et al. (1988: Hum Biol 60: 709-723) regression equation and cardiorespiratory fitness (CRF) was assessed using …

Relative Fat Mass: Refining Adiposity Measurement in the Era Beyond Body Mass Index.

To position relative fat mass (RFM) as a more accurate, physiologically grounded, and clinically useful alternative to body mass index (BMI) for assessing adiposity and predicting cardiometabolic risk, including heart failure.  RECENT FINDINGS: RFM estimates body fat percentage using a sex-specific formula based on waist circumference and height. RFM not only correlates more strongly with fat mass than BMI, but also shows a weaker correlation with muscle mass. This distinction helps reduce lean mass-related confounding in the assessment of adiposity. In clinical studies, RFM has emerged as a r…

Tracking of Obesity in Childhood into Adulthood: Effects on Body Mass Index and Fat Mass Index at Age 50.

Background: Obesity is present in 17% of US youth, age 2-19 years, but the extent to which obesity in childhood is associated with higher BMI and fat mass in middle age is unclear. In this study, links between childhood body size and BMI and body composition at age ∼50 were assessed. Methods: Child Health and Development Studies participants, born between 1960 and 1963 in Alameda County, and still living in California, from whom anthropometric data were collected at age 5, 9-11, and/or 15-17 years were followed-up at age ∼50 for anthropometric outcomes (251 women; 249 men). Linear regression a

Predictors of Treatment Outcome in Persons With Anorexia Nervosa: On the Practice of Regressing Body Mass Index at the End of Treatment on Body Mass Index at Baseline.

OBJECTIVE: It is often stated that a higher body mass index (BMI) at the beginning of treatment predicts a better weight outcome at the end of treatment in persons with anorexia nervosa (AN). However, this interpretation is based on the between-persons relationship of BMI at the two measurements, which primarily reflects the fact that the rank-ordering of persons according to their BMI is quite stable over time. In contrast, a lower BMI at baseline is related to a larger BMI change, which primarily reflects the fact that the variance of BMI at the end of treatment is larger than that at baseli…

Relationships of maternal body mass index and plasma biomarkers with childhood body mass index and adiposity at 6 years: The Children of SCOPE study.

BACKGROUND: Maternal obesity has been implicated in the origins of childhood obesity through a suboptimal environment in-utero. OBJECTIVE: We examined relationships of maternal early pregnancy body mass index (BMI), overweight/obesity, and plasma biomarkers of obesity, inflammation, insulin resistance, and placental function with measures of childhood BMI and adiposity. METHODS: BMI z-score, sum of skinfold thicknesses (SST), body fat percentage (BFP, by bioelectrical impedance), and waist, arm, and hip circumferences were measured in 1173 6-year-old children of nulliparous pregnant women in…

The impact of body mass index on pancreatic fistula after pancreaticoduodenectomy in Asian patients on the basis of Asia-Pacific perspective of body mass index.

CONTEXT: Several surgical complications are related to obesity. OBJECTIVE: This study evaluated the impact of obesity on pancreatic fistula after pancreaticoduodenectomy. DESIGN: We retrospectively reviewed the medical records of 159 patients who underwent pancreaticoduodenectomy between October 2002 and December 2008. SETTING: The patients were divided according to the body mass index as obese (body mass index equal to, or greater than, 25 kg/m(2)), or normal (body mass index less than 25 kg/m(2)). METHODS: Univariate and multivariate analyses were applied. Two-tailed P values less than 0…

Beyond Body Mass Index: Appendicular Lean Mass Index-Defined Sarcopenia and Carpal Tunnel Syndrome-A Cross-Sectional Analysis.

INTRODUCTION/AIMS: Obesity is a well-established risk factor for carpal tunnel syndrome (CTS), but body mass index (BMI) does not distinguish adiposity from skeletal muscle mass. The role of sarcopenia in CTS has received little attention. Sarcopenia may increase nerve vulnerability to compression. We examined whether appendicular lean mass index (ALMI) and ALMI-defined sarcopenia are associated with CTS independent of BMI. METHODS: We retrospectively analyzed 193 consecutive patients aged 50 years or older who underwent carpal tunnel release by a single surgeon at a tertiary center over 4 ye…

Relationship Between Body Mass Index and Fat Mass Percentage with Proprioception in Children.

BACKGROUND/OBJECTIVES: Childhood obesity is linked to motor and sensorimotor impairments, including proprioceptive deficits. While research has predominantly focused on lower limb proprioception, less is known about the impact on upper limbs. This study investigated the relationship between body mass index, body fat percentage, and proprioception of children aged 11-12 years. METHODS: A quantitative, correlational, observational design was employed. BMI was calculated from weight and height measurements, body fat percentage was assessed via bioelectrical impedance analysis, and proprioception…

Развенчание циркуляции и циркуляции гипса по индексу массы тела с индексом формы тела, индексом гипса и показателем антропометрического риска.

Индекс массы тела (ИОВ) корректирует вес тела по высоте и хорошо установлен для диагностики избыточного веса и ожирения и соотносится со многими медицинскими условиями. Для диагностики ожирения в брюшной полости используется длина окружности (ВЦ). Однако корреляция между BMI и WC является высокой, примерно 0,9, что затрудняет использование BMI и WC в концерте. Индекс формы кузова (АБСИ) представляет собой новый показатель риска, связанного с размером брюшной полости. Полученный в 2012 году АБСИ аналогичен ИБМ в том смысле, что он нормализует ВК для веса и роста (и, таким образом, ИБМ). Аналоги

Body mass index (BMI) corrects body weight for height and is well established for diagnosing overweight and obesity and correlating with many medical conditions. Waist circumference (WC) is used to diagnose abdominal obesity. However, the correlation of BMI and WC is high, around 0.9, making the use of BMI and WC in concert challenging. A body shape index (A…

Tri-Ponderal Mass Index vs body Mass Index in discriminating central obesity and hypertension in adolescents with overweight.

BACKGROUND AND AIMS: Recently, it has been hypothesized that Tri-Ponderal Mass Index (TMI) may be a valid alternative to Body Mass Index (BMI) when measuring body fat in adolescents. We aimed to verify whether TMI has better accuracy than BMI in discriminating central obesity and hypertension in adolescents with overweight. METHODS AND RESULTS: This monocentric and retrospective cross-sectional study included 3749 pupils, 1889 males and 1860 females, aged 12-13. BMI (kg/m2) was calculated and expressed as percentiles and as z-scores. TMI (kg/m3) was calculated, and we used pre-defined cut-off…

Triponderal mass index rather than body mass index: An indicator of high adiposity in Italian children and adolescents.

OBJECTIVE: The aims of this study were to compare body mass index (BMI) and triponderal mass index (TMI) as predictors of fat mass percentage (FM%) and to develop TMI cutoffs for screening high adiposity. Therefore, TMI- and BMI-based references against FM% criterion for indicating adiposity in Italian children and adolescents were compared. METHODS: This was a cross-sectional study conducted at the University of Rome Tor Vergata, Human Nutrition Unit, from 2008 to 2015. The sample included 485 children and adolescents from 8 to 17 y of age from central-southern Italy. Body weight (kg) and he…

Defining Overweight and Obesity by Percent Body Fat Instead of Body Mass Index.

OBJECTIVE: Thresholds for overweight and obesity are currently defined by body mass index (BMI), a poor surrogate marker of actual adiposity (percent body fat [%BF]). Practical modern technologies provide estimates of %BF but medical providers need outcome-based %BF thresholds to guide patients. This analysis determines %BF thresholds based on key obesity-related comorbidities, exhibited as metabolic syndrome (MetSyn). These limits were compared to existing BMI thresholds of overweight and obesity. DESIGN: Correlational analysis of data from cross sectional sampling of 16 918 adults (8734 men…

Body mass index, body fat and risk factor of relapse in anorexia nervosa.

BACKGROUND/OBJECTIVES: Preliminary studies have reported an association between poor long-term outcome and lower total body fat percentage in weight-restored inpatients treated for anorexia nervosa (AN). A possible link between poor long-term outcome and higher trunk fat percentage has also been hypothesized. The aim was to assess the association between percentage and distribution of body fat at inpatient discharge and the maintenance of normal weight at 1-year follow-up in a sample of weight-restored females with AN. SUBJECTS/METHODS: Fifty-four short-term weight-restored (body mass index (…

Associations of body roundness index and body mass index with obstructive sleep apnea: evidence from two cohorts study.

BACKGROUND: Obstructive sleep apnea (OSA) is closely associated with obesity. Traditional anthropometric indices body mass index (BMI) could not assess body fat content precisely. The body roundness index (BRI) has emerged as a novel adiposity metric reflecting central fat distribution. This study aimed to compare BRI and BMI in assessing the risk and worsening of OSA severity in community-based cohort study. METHODS: We analyzed data from two well-characterized cohorts: the Osteoporotic Fractures in Men Study (MrOS) and the Sleep Heart Health Study (SHHS). Statistical and machine learning ap…

Body Fat Percentage, Body Mass Index, Fat Mass Index and the Ageing Bone: Their Singular and Combined Roles Linked to Physical Activity and Diet.

This study took a multi-analytical approach including group differences, correlations and unit-weighed directional z-score comparisons to identify the key mediators of bone health. A total of 190 participants (18⁻80 years) were categorized by body fat%, body mass index (BMI) and fat mass index (FMI) to examine the effect of differing obesity criteria on bone characteristics. A subset of 50 healthy-eating middle-to-older aged adults (44⁻80 years) was randomly selected to examine any added impact of lifestyle and inflammatory profiles. Diet was assessed using a 3-day food diary, bone mineral den…

Is body mass index associated with mortality in patients with sepsis?

BACKGROUND: There is controversy whether patients with higher body mass indexes (BMI) have better survival after sepsis. OBJECTIVE: To determine if the association between BMI and mortality persists after adjustment for weight loss, comorbidities, and nutritional status. METHOD: In this single-center retrospective study of patients meeting Sepsis-3 criteria between July 10, 2009 and September 7, 2019, we used logistic regression to adjust BMI for weight loss, comorbidities, culture results, demographics, laboratory values, and processes of care. We transformed BMI using fractional polynomial…
