Objective: To evaluate body image dissatisfaction and its relationship with physical activity and body mass index in a Brazilian sample of adolescents. Methods: A total of 275 adolescents (139 boys and 136 girls) between the ages of 14 and 18 years completed measures of body image dissatisfaction through the Contour Drawing Scale and current physical activity by the International Physical Activity Questionnaire. Weight and height were also measured for subsequent calculation of body mass index. Results: Boys and girls differed significantly regarding body image dissatisfaction, with girls reporting higher levels of dissatisfaction. Underweight and eutrophic boys preferred to be heavier, while those overweight preferred be thinner and, in contrast, girls desired to be thinner even when they are of normal weight. Conclusion: Body image dissatisfaction was strictly related to body mass index, but not to physical activity.

OBJECTVE: To objectively and critically assess body mass index and to propose alternatives for relating body weight and height that are evidence-based and that eliminate or reduce the limitations of the body mass index. METHODS: To analyze the relations involving weight and height, we used 2 databases as follows: 1) children and adolescents from Brazil, the United States, and Switzerland; and 2) 538 university students. We performed mathematical simulations with height data ranging from 115 to 190 cm and weight data ranging from 25 to 105 kg. We selected 3 methods to analyze the relation of weight and height as follows: body mass index - weight (kg)/height (m²); reciprocal of the ponderal index - height (cm)/weight1/3 (kg); and ectomorphy. Using the normal range from 20 to 25 kg/m² for the body mass index in the reference height of 170 cm, we identified the corresponding ranges of 41 to 44 cm/kg1/3 for the reciprocal of the ponderal index, and of 1.45 to 3.60 for ectomorphy. RESULTS: The mathematical simulations showed a strong association among the 3 methods with an absolute concordance to a height of 170 cm, but with a tendency towards discrepancy in the normal ranges, which had already been observed for the heights of 165 and 175 cm. This made the direct convertibility between the indices unfeasible. The reciprocal of the ponderal index and ectomorphy with their cut points comprised a larger age range in children and adolescents and a wider and more central range in the university students...

As a part of a management program we captured 39 capybaras (Hydrochoerus hydrochaeris) in an agroecosystem at the east central region of the State of São Paulo, Brazil from March 2001 to May 2002. Average adult male body mass was 54.1 ± 8.05 kg, and average adult female body mass was 62.0 ± 12.03 kg. Average juvenile male body mass was 23.0 ± 8.28 kg, and average juvenile female body mass was 26.7 ± 5.86 kg. Males and females presented a significant variation in the allometric relation between body mass and body length. Body mass and body length had a high correlation for both adult males and adult females. These results from capybaras in agroecosystem might be relevant for further management programs.

Objective To analyse the progression of body mass index in eating disorders and to determine the percentile for establishment and resolution of the disease. Methods A retrospective descriptive cross-sectional study. Review of clinical files of adolescents with eating disorders. Results Of the 62 female adolescents studied with eating disorders, 51 presented with eating disorder not otherwise specified, 10 anorexia nervosa, and 1 bulimia nervosa. Twenty-one of these adolescents had menstrual disorders; in that, 14 secondary amenorrhea and 7 menstrual irregularities (6 eating disorder not otherwise specified, and 1 bulimia nervosa). In average, in anorectic adolescents, the initial body mass index was in 75th percentile; secondary amenorrhea was established 1 month after onset of the disease; minimum weight was 76.6% of ideal body mass index (at 4th percentile) at 10.2 months of disease; and resolution of amenorrhea occurred at 24 months, with average weight recovery of 93.4% of the ideal. In eating disorder not otherwise specified with menstrual disorder (n=10), the mean initial body mass index was at 85th percentile; minimal weight was in average 97.7% of the ideal value (minimum body mass index was in 52nd percentile) at 14.9 months of disease; body mass index stabilization occured at 1.6 year of disease; and mean body mass index was in 73rd percentile. Considering eating disorder not otherwise specified with secondary amenorrhea (n=4); secondary amenorrhea occurred at 4 months...

PURPOSE: Obesity is associated with cardiovascular disease, affecting large arteries and the microcirculation. Waist circumference and body mass index are routinely employed as measures for assessing obesity-related health risk, whereas waist-to-hip ratio is not. We aimed to investigate the association between brachial vascular reactivity and body mass index, waist circumference, and waist-to-hip ratio. METHODS: Eighty-five volunteers (21 men/66 women), aged between 20 and 55 years, underwent determination of waist circumference, body mass index, waist-to-hip ratio, and endothelial function by venous occlusion plethysmography. Forearm blood flow was measured in response to intrabrachial artery infusions of 3 different concentrations of endothelium-dependent (acetylcholine 7.5, 15, and 30 mg/min) and endothelium-independent (sodium nitroprusside 2, 4, and 8 mg/min) vasodilators. RESULTS: There was an inverse correlation of body mass index and waist circumference with forearm blood flow increments after acetylcholine and sodium nitroprusside infusions, while waist-to-hip ratio showed an inverse correlation with forearm blood flow increments only after acetylcholine. When subjects older than 40 years (n = 25) were excluded from the analysis...

Body mass is thought to influence diversification rates, but previous studies have produced ambiguous results. We investigated patterns of diversification across 100 trees obtained from a new Bayesian inference of primate phylogeny that sampled trees in proportion to their posterior probabilities. First, we used simulations to assess the validity of previous studies that used linear models to investigate the links between IUCN Red List status and body mass. These analyses support the use of linear models for ordinal ranked data on threat status, and phylogenetic generalized linear models revealed a significant positive correlation between current extinction risk and body mass across our tree block. We then investigated historical patterns of speciation and extinction rates using a recently developed maximum-likelihood method. Specifically, we predicted that body mass correlates positively with extinction rate because larger bodied organisms reproduce more slowly, and body mass correlates negatively with speciation rate because smaller bodied organisms are better able to partition niche space. We failed to find evidence that extinction rates covary with body mass across primate phylogeny. Similarly, the speciation rate was generally unrelated to body mass...

Issues of body image and ability to achieve intimacy are connected to body weight, yet remain largely unexplored and have not been evaluated by gender. The underlying purpose of this research was to determine if avoidant attitudes and perceptions of one’s body may hold implications toward its use in intimate interactions, and if an above average body weight would tend to increase this avoidance. The National Health and Nutrition Examination Survey (NHANES, 1999-2002) finds that 64.5% of US adults are overweight, with 61.9% of women and 67.2% of men. The increasing prevalence of overweight and obesity in men and women shows no reverse trend, nor have prevention and treatment proven effective in the long term. The researcher gathered self-reported age, gender, height and weight data from 55 male and 58 female subjects (determined by a prospective power analysis with a desired medium effect size (r =.30) to determine body mass index (BMI), determining a mean age of 21.6 years and mean BMI of 25.6. Survey instruments consisted of two scales that are germane to the variables being examined. They were (1) Descutner and Thelen of the University of Missouri’s (1991) Fear-of-Intimacy scale and (2) Rosen, Srebnik, Saltzberg, and Wendt’s (1991) Body Image Avoidance Questionnaire. Results indicated that as body mass index increases...

OBJECTIVES: To determine the proportion of a representative population sample of adults in South Australia who have a body mass index (a measure of overall obesity) classified as normal or underweight, but who also have a waist circumference or waist hip ratio (measures of central obesity) that indicates obesity. METHODS: A representative population sample of adults aged 18 years and over living in the north west region of Adelaide (n = 2523) were recruited to the study. Clinical measures of height, weight, waist and hip circumference were obtained and used to determine body mass index, waist hip ratio and waist circumference. RESULTS: Among women with a normal body mass index, 19.0% had a high waist circumference ( 80 cm) and 8.5% had a high waist hip ratio (> 0.85). Among males with a normal body mass index, 3.4% had a high waist circumference ( 95 cm) and 0.1% had a high waist hip ratio (>1.0). CONCLUSIONS: Body mass index, waist hip ratio and waist circumference all have a role in the identification of those who are obese or overweight.; Tiffany Gill, Catherine Chittleborough, Anne Taylor, Richard Ruffin, David Wilson and Patrick Phillips; © Birkhäuser

OBJECTIVE Investigate the effect of exposure to smoking during pregnancy and early childhood on changes in the body mass index (BMI) from birth to adolescence.METHODS A population-based cohort of children (0-5 years old) from Cuiabá, Midwest Brazil, was assessed in 1999-2000 (n = 2,405). Between 2009 and 2011, the cohort was re-evaluated. Information about birth weight was obtained from medical records, and exposure to smoking during pregnancy and childhood was assessed at the first interview. Linear mixed effects models were used to estimate the association between exposure to maternal smoking during pregnancy and preschool age, and the body mass index of children at birth, childhood and adolescence.RESULTS Only 11.3% of the mothers reported smoking during pregnancy, but most of them (78.2%) also smoked during early childhood. Among mothers who smoked only during pregnancy (n = 59), 97.7% had smoked only in the first trimester. The changes in body mass index at birth and in childhood were similar for children exposed and those not exposed to maternal smoking. However, from childhood to adolescence the rate of change in the body mass index was higher among those exposed only during pregnancy than among those who were not exposed.CONCLUSIONS Exposure to smoking only during pregnancy...

PURPOSE: To evaluate variations in the body mass index in patients undergoing adjuvant chemotherapy for breast cancer, and to associate these changes with patient's age and adjuvant chemotherapy regimen. METHODS: We performed a retrospective cohort study in order to correlate any variation in the body mass index before and after adjuvant chemotherapy with patient's age and adjuvant chemotherapy regimen. Patients who received any form of prior hormone therapy, such as tamoxifen or aromatase inhibitors, were excluded. We selected data for 196 patients with stage I to III breast cancer who were treated by radical or conservative surgery and received adjuvant chemotherapy at the Cancer Institute of the State of São Paulo, Brazil. RESULTS: Before adjuvant chemotherapy, 67.8% of patients were classified as overweight or obese according to their body mass indices. Around 66.3% (95% CI 59.7–73.0) of the patients exhibited an increase in the body mass index after adjuvant chemotherapy. The average age of all patients was 56.3±11.3 years. Participants whose body mass index increased were younger than those with no increase (54.7±11.1 versus 59.3±11.2 years; p=0.007). Patients were treated with the following adjuvant chemotherapy regimens: doxorubicin...

It is evident from literature that an increased body mass index (BMI) may be a potential risk factor for periodontitis. Association between BMI and periodontitis has been ascribed to unhealthy dietary patterns with insufficient micronutrients and excess sugar and fat content. The present study population has been plagued by unhealthy nutritional practices, hence the present study intended to assess the relation between BMI and periodontal status among green marble mine laborers of Kesariyaji, in the Udaipur district of Rajasthan, India. The study sample comprised of 513 subjects aged 18-54 years, drawn using the stratified cluster sampling procedure. BMI was calculated as the ratio of the subject's body weight (in kg) to the square of their height (in meters). Periodontal status was recorded using the Community Periodontal Index (CPI). Binary multiple logistic regression analysis was executed to assess the relation between body mass index and periodontitis. The dependent variable for logistic regression analysis was categorized into control group (scores 0 - 2 of the CPI) and periodontitis group (scores 3 and 4 of the CPI). The overall prevalence of periodontal disease was 98.2%. Caries status and mean number of teeth present deteriorated with the poor periodontal status. Subjects had an increased risk of periodontitis by 57% for each 1kg/m² increase in the body mass index...

[ES] Los objetivos del presente trabajo son: 1) inferir la masa corporal de los Hipparionini de la península ibérica; y 2) enmarcar el patrón de cambios en la masa corporal dentro de la evolución climático-ambiental de la península ibérica durante el lapso Mioceno superior-Plioceno superior. La masa corporal se estimó a partir del ancho de la superficie articular de la primera falange del dedo central, utilizándose para ello una ecuación de regresión. Una vez estimada la masa corporal, se la correlacionó con dos indicadores paleoecológicos, el índice de gracilidad (IG) y el de hipsodoncia (IH). El patrón de cambios en la masa corporal a través del tiempo se analizó considerando como unidades cronológicas las Edades-mamífero (ELMAs) y las zonas de Mein (MN). Los resultados obtenidos muestran que: 1) la mayoría de los fósiles (32 %) habrían alcanzado una masa que se ubica en el intervalo comprendido entre los 150 y los 199 Kg., siguiéndoles en número aquellos cuya masa se hallaría comprendida entre los 100 y los 149 Kg. (26 %). Las tallas extremas (i.e., 0-49; 300-349 y 350-399 Kg.) habrían tenido una frecuencia mucho menor (5%), estando representada cada una de ellas por un solo taxón; 2) a lo largo de su biocrón...

We studied the effect of daily body mass increase on the foraging preferences of two tit species, crested tit, Parus cristatus and blue tit, P. caeruleus, contrasting in morphology and behaviour. We found that both species show a diurnal increase in body mass during winter. Using an experiment with feeders we show that in the crested tit, the proportion of time spent foraging while hanging decreased as body mass increased. In contrast, in the blue tit, foraging behaviour did not change with mass gain. We propose that the species with a morphological design providing a high ecological plasticity in terms of foraging postures can counteract the negative effect of body mass on the ecological options (foraging niche) more than species with a morphological design providing a low ecological plasticity in terms of foraging postures. Our results suggest that blue tits had the advantage of being able to choose to feed on different patches in the habitat throughout the day, which makes resources more predictable for them. In contrast, crested tits might be more restricted in their foraging options as their body mass increases, and this might explain why they hoard food.; This study was funded by projects PB95 0103 and PB 98 0506 of the Spanish Ministry of Science and Technology.; Peer reviewed

Crianças com paralisia cerebral devido às desordens de movimento e postura podem ter o seu estado nutricional comprometido. Assim, este estudo tem como objetivo classificar o índice de massa corpórea de crianças com paralisia cerebral e verificar se existe relação com o grau de comprometimento da função motora grossa. Para tanto, participaram do estudo 20 crianças com paralisia cerebral, com idade entre dois e 14 anos, do sexo masculino e feminino, atendidas em um centro de reabilitação com acompanhamento de fisioterapia, terapia ocupacional e fonoaudiologia. Todas foram classificadas de acordo com a escala de classificação da função motora grossa. Foram realizadas as medidas antropométricas de cada criança: peso; comprimento calcanhar-joelho; estatura estimada e índice de massa corpórea. O índice de massa corpórea foi classificado de acordo com o percentil do índice de massa corpórea de crianças e adolescentes do Center for Disease Control and Prevention. Os dados obtidos não permitiram identificar relação entre a classificação da função motora grossa e índice de massa corpórea. Talvez o número reduzido de participantes e o fato de todas as crianças serem acompanhadas em ambulatório de disfagia e...

OBJETIVO: A obesidade é associada a doenças cardiovasculares e compromete tanto a macro como a microcirculação. As medidas da cintura e do índice de massa corpórea são rotineiramente empregadas para avaliação do risco cardiovascular em obesos, enquanto a relação cintura-quadril é pouco utilizada. O objetivo do trabalho foi determinar que medida antroprométrica, entre as rotineiramente usadas, avalia melhor o risco cardiovascular em obesos. MATERIAL E MÉTODO: Oitenta e quatro voluntários (21 homens/ 66 mulheres), idade entre 20 e 55 anos foram avaliados quanto ao diâmetro da cintura, ao índice de massa corpórea, à relação cintura-quadril e à função endotelial pela técnica de pletismografia com oclusão venosa para medida do fluxo sanguíneo braquial, em resposta a injeção intrabraquial de três doses de acetilcolina (7,5; 15 e 30 mg/min) ou de nitroprussiato de sódio (2; 4 e 8 mg/min), para avaliação da vasodilatação endotélio-dependente e -independente. RESULTADO: Houve correlação inversa entre o índice de massa corpórea, diâmetro da cintura e aumento do fluxo sanguíneo após injeção de acetilcolina e nitroprussiato de sódio, enquanto que a relação cintura-quadril mostrou uma correlação negativa apenas com o aumento no fluxo de sangue no antebraço...

OBJETIVO Analisar se a exposição ao tabagismo materno durante a gravidez e no início da infância afeta as mudanças no índice de massa corporal entre o nascimento e a adolescência. MÉTODOS Realizado estudo de coorte de base populacional com 2.405 crianças (0 a 5 anos) nascidas em Cuiabá, Brasil, e avaliadas de 1999 a 2000. De 2009 a 2011, esse grupo foi reavaliado. Peso ao nascer foi obtido a partir de registros médicos e a exposição ao tabagismo durante a gravidez e infância foi avaliada na primeira entrevista. Modelos lineares de efeitos mistos foram utilizados para estimar a associação entre a exposição ao tabagismo materno, durante a gravidez e a fase pré-escolar, e o índice de massa corporal das crianças ao nascer e durante a infância e adolescência. RESULTADOS Apenas 11,3% das mães relataram fumar durante a gravidez, sendo que a maioria delas (78,2%) também fumou durante a fase pré-escolar da criança. Entre as mães que fumaram exclusivamente durante a gravidez (n = 59), 97,7% fumaram somente no primeiro trimestre. As mudanças de índice de massa corporal entre o nascimento e a infância foram semelhantes entre as crianças expostas e não expostas ao tabagismo materno. Entretanto, entre a infância e a adolescência...

OBJETIVO: Analisar as relações entre o índice de massa corporal e a autopercepção da imagem corporal. MÉTODOS: Foram avaliados 106 estudantes universitários, de ambos os sexos, maiores de 18 anos, na região de Ribeirão Preto, Estado de São Paulo, em 2003. Para avaliar a percepção da imagem corporal, utilizou-se uma escala de silhuetas e uma escala visual analógica; a primeira aplicada por dois métodos psicométricos distintos. Para a avaliação do componente subjetivo da imagem corporal foi aplicado um questionário sobre imagem corporal. A avaliação do estado nutricional considerou a classificação do índice de massa corporal. Os dados foram submetidos à análise de variância e teste post-hoc de Newman-Keuls. RESULTADOS: A maioria das mulheres eutróficas ou com sobrepeso (87%) superestimaram seu tamanho corporal enquanto mulheres obesas e homens (73%), independente do índice de massa corporal, subestimaram o tamanho corporal. As diferenças devido a gênero foram estatisticamente significativas, bem como a insatisfação geral com a imagem corporal percebida, mostrado pelo desejo por menores valores do índice de massa corporal. As mulheres com sobrepeso apresentaram maior preocupação e desconforto com o corpo. CONCLUSÕES: Tanto homens como mulheres apresentaram distorção na autopercepção da imagem corporal...

The aging is a complex process, where alterations of body composition determine structural and functional changes in the human body. This study aims to analyze the anthropometric and body composition (fat mass and lean body mass) alterations after a physical rehabilitation program in elderly women, and to verify these alterations between status of BMI. The sample consisted of 160 elderly women (63.8 ± 2.9 years) engaged in a program of systematic activities for twelve weeks. Anthropometric and body composition before and after the intervention period were performed. BMI was used to evaluate body composition as well as the nutritional status. After intervention, significant reductions were observed in total body mass (68.2 ± 9.4 vs 67.2 ± 9.3, p < 0.001), fat mass (23.9 ± 5.3 vs 23.4 ± 5.0, p = < 0.001) , lean body mass (44.3 ± 5.2 vs 43.8 ± 5.3, p < 0.001) and BMI (21.8 ± 3.0 vs 21.4 ± 3.0, p = < 0.001). Significant differences among BMI strata were observed (p <0.001).

Aim: To assess the relationship between time spent in front of a screen and studying, body mass index (BMI), smoking, and sleep duration among university students. Material and Methods: A cross-sectional study of 734 randomly selected students aged 21 ±2 years (450 females) that responded an anonymous, structured questionnaire about time spent watching television or in front of a computer, time spent studying, number of daily hours of sleep, smoking habits and number of daily meals. Body mass index was also calculated for all subjects Results: Among males, the number of daily sleep hours, time spent working with computers and number of daily meals were significantly higher and time spent studying was significantly lower than females. Nonsmokers ate a significantly higher number of meals and spent less time watching television. No association was observed between time spent in front of a screen and number of sleep hours of body mass index. Conclusions: Men and smokers spend more time working in computers. There is no association between body mass index and time spent in front of screens.
