Anthropometric and body composition indicators of Bahraini adolescents

BACKGROUND: Childhood and adolescent obesity tends to extend into adulthood and predisposes the individual to some chronic diseases in later life. Body composition is a good indicator for assessing obesity and nutritional status of people. AIM: To determine the anthropometric and body composition characteristics of Bahraini adolescents and to compare these measurements with previously published data on the same age group. SUBJECTS OF METHODS: Cross-sectional data on 506 Bahraini adolescents (249 boys and 257 girls) aged 12-17 years were collected in 2000. The sample was selected from intermediate and secondary schools using a multistage stratified sampling procedure. Anthropometric measurements, including weight, height, mid upper arm circumference, waist and hip circumference, triceps, subscapular and medial calf skinfold thickness, were performed on the adolescents. Body mass index (BMI), percent body fat, arm muscle circumference (AMC), arm muscle area (AMA), arm fat area (AFA), waist/hip ratio (WHR), and subscapular/triceps skinfold ratio (STR) were also calculated. RESULTS: A sexual dimorphism that appears to be related to differential changes in body composition during puberty was observed. The findings showed that mean BMI, skinfold thickness and percent body fat were all higher than those reported in earlier studies on Bahraini adolescents of corresponding age range, indicating an increase in fat accumulation among the adolescent population. Bahraini adolescents were found to be shorter and of similar weight or even heavier than their Western counterparts, indicating a greater trend of obesity among Bahraini adolescents. CONCLUSION: A trend of greater obesity appears to have occurred in the Bahraini adolescents during the period between 1986 and 2000. These findings have important public health implications given recent evidence linking childhood and adolescent obesity to increased risk of obesity and morbidity in adulthood. Therefore, programmes to prevent the development of obesity in children and adolescents should be given a high priority.     

Association of serum C-reactive protein and indices of body fat distribution and overweight in Mexican American children

BACKGROUND: Few data have been published on the association of indices of body fat distribution and components of the insulin resistance syndrome and serum C-reactive protein (CRP), an acute phase protein and putative risk factor for cardiovascular morbidity, in representative samples of total populations of children or in Hispanic Americans, who have a high prevalence of obesity and diabetes as adults. OBJECTIVE: To evaluate the association of waist-to-hip ratio (WHR) and body mass index (BMI) and components of the insulin resistance syndrome with CRP in Mexican American children and to assess the independence of the association. DESIGN: Cross-sectional survey of a large national sample, the Third National Health and Nutrition Examination Survey. PARTICIPANTS: Mexican American children aged 6-11 years. MEASUREMENTS: Body circumferences, skinfold thickness, BMI, blood pressure, and serum CRP and lipid concentrations. RESULTS: Overall, 11% of children had detectable CRP (> 0.21 mg/dL). CRP was not associated with age, gender, or birth weight. WHR showed significant positive associations with serum CRP concentration independent of BMI. BMI was also significantly associated with CRP independent of WHR. CRP was significantly associated with HDL cholesterol but not triglyceride, or systolic blood pressure, concentration after controlling for BMI. CONCLUSION: Further research is needed on the associations of serum CRP concentration with WHR and other indices of body fat distribution and obesity to elucidate the mechanisms and significance of these associations.     

Percentiles of waist–hip ratio and the relationship with blood pressure among children and adolescents in Shandong,China

Background: Anthropometric indices such as waist circumference (WC), waist-to-height ratio (WHtR) and waist–hip ratio (WHR) have been recognized as useful alternatives to visceral fat measurement in epidemiological studies. WHR has been used extensively in adults. However, there are very few published data for WHR among children and adolescents.

Aim: The present study examined the distribution of WHR and the relationship with blood pressure (BP) among children and adolescents in Shandong, PR China.

Subjects and methods: Data for this study were obtained from a large cross-sectional survey of schoolchildren carried out in 2010. A total of 38?822 students (19?456 boys and 19?366 girls) aged 7–17 years participated in this study. WC, Hip circumference (HC), systolic blood pressure (SBP) and diastolic blood pressure (DBP) of all subjects were measured; WHR was calculated as WC divided by HC. Abdominal obesity was defined by previously published WHR references based on Chinese children and adolescents living in Beijing. All subjects were divided into two groups (group 1 with WHR <85th; group 2 with WHR ≥85th) according to the percentiles of WHR and comparisons of the SBP and DBP between the two groups were made.

Results: The WHR levels in Shandong boys and girls were lower than those from German and Pakistani. The overall prevalence of abdominal obesity was 9.53% (95% CI?=?9.12–9.95%) for boys and 9.82% (95% CI?=?9.40–10.24%) for girls, no statistical differences between the two genders were observed (p?>?0.05). In both boys and girls, the Z-scores of SBP and DBP were all significantly lower in group 1 than in group 2 (p?Conclusion: WHR is useful in identifying children and adolescents at risk of developing high BP. These findings, together with the known tracking of BP from adolescence into adulthood, highlight the importance of preventing overweight and obesity among children and adolescents in order to prevent the development of hypertension in adults.     

Health-related morphological characteristics and physiological fitness in connection with nutritional,socio-economic status,occupational workload of tea garden workers

Background

Reports on the cardiorespiratory fitness and body composition of male workers engaged in processing of tea leaves in factories within the tea-estates of West Bengal, under the influence of physiological workload, are quite scanty.

Objectives

This cross-sectional study was conducted to evaluate morphometric characteristics based on physiological status and physical fitness of tea factory laborers who are continuously exposed to tea dust in their work environment for more than two years.

Methods

Subjects were divided into control and tea garden workers groups. Height and weight were measured and the body mass index (BMI) was computed. Physiological parameters such as resting heart rate, blood pressure, fitness variables like physical fitness index (PFI), energy expenditure (EE), handgrip strength and anthropometric parameters like mid-upper arm (MUAC), thigh circumference (TC), head circumference (HC) and waist-to-hip ratio (WHR) were measured.

Results

Body surface area (BSA), BMI, body fat percentage and fitness variables (PFI, EE) showed significant difference (p<0.05) between the two groups. Anthropometric measures (MUAC, TC, HC, WHR) reflected poor status among laborers.

Conclusions

The present study shows that the majority of workers had ectomorph stature, good physical fitness, but had poor nutritional status (BMI and WHR)     

Association of waist and hip circumferences with the presence of hypertension and pre-hypertension in young South African adults

BackgroundObesity is one of the most important risk factors for cardiovascular diseases (CVDs) including hypertension (HT) which is itself a risk factor for CVDs. Recent studies suggest that waist circumference (WC) may be more sensitive than Body Mass Index (BMI) in determining individual risk scores for CVDs.ObjectivesThe current study aimed at investigating the influence of various anthropometric variables on blood pressure status in a group of students from Walter Sisulu University.MethodsInformed consent was obtained from 216 male and female students from Walter Sisulu University with a mean age of 22.1±0.2 years. Anthropometric measurements were performed for each participant. Blood pressure was measured in triplicates after 10 minutes of rest and the average computed.ResultsJust over 46% of the subjects were diagnosed with hypertension (HT) and pre-HT. The gender specific prevalence of HT/pre-HT was higher in the male (76.7%) compared to the female (30.5%) group. Waist circumference (WC) and total body fat (TBF) correlated significantly with blood pressure and HT/pre-HT in females but not males. ROC analysis showed that with the exception of waist-to-hip (WHR), all other anthropometric measurements and ratios studied can be used to discriminate blood pressure in young adult females not males.ConclusionIncreased WC and HC were associated with HT and pre-HT in young adult females in the Walter Sisulu University.     

Study of growth in rural school children from Buenos Aires, Argentina using upper arm muscle area by height and other anthropometric dimensions of body composition

The primary objective was to compare growth and body composition in an infantile rural population by means of the upper arm muscle area by height and other antropometric measurements. Research was carried out by way of a cross sectional study, including 80% (321 6-13 year olds) of the schoolchildren living in General Lavalle, a rural community of about 3000 inhabitants. The methods and procedures included the evaluation of mother's educational levels and anthropometric measurements. Height (H), weight, mid upper arm circumference, and triceps skinfold (TS) were measured. The body mass index (BMI), the upper arm muscle area (UAMA), the upper arm fat area (UAFA) and the upper arm muscle area by height (UAMAH) were calculated. Variables were grouped by gender and age and transformed into z-scores, using the US anthropometric standards as reference. The results showed that: (1) the mother educational status was, in relation to z-scores, as in an urban population, and (2) the z-scores for BMI, UAFA and TS were above the reference, while the ones for H, UAMA and UAMAH were below the reference. The differences between z-scores in relation to mother's educational levels were statistically significant (p < 0.05). UAMA was correlated strongly with H (r = 0.67). The children of General Lavalle tend to be fatty and overweight, while their muscle mass and H are proportionally low, but with values within the reference. Thus, low muscle mass and H are, in general terms, indicative of low protein reserves, the systematically low-anthropometry found for UAMAH suggests that this index should be used in conjunction with other indexes (e.g. BMI, UAFA) to obtain a more complete assessment of body composition and nutritional status.     

Conicity: A new index of body fat distribution—what does it tell us?

“Conicity” (C) is an index of body fat distribution which expresses an individuals waist circumference relative to the circumference of a cylinder generated with that persons weight and height assuming a constant for body density (Valdez [1991] J. Clin. Epidemiol. 44:955–956). The more central a person is in fat distribution, the higher the value of C. In a pilot study of cardiovascular reactivity and dimensions of anger and hostility in 60 African-, Anglo-, and Hispanic-American adolescents, anthropometry and sexual maturation were determined to assess their mediating influence on the relation between anger and cardiovascular risk. The concurrent validity of three indices of body fat distribution was explored: conicity(C), waist/hip ratio (WHR), and central/peripheral skinfold ratio (C/P) by assessing their association with cardiovascular variables (CV) and other anthropometrics. Anthropometry included height, weight, fat mass estimated from bioelectrical impedance, four circumferences, and skinfolds. Maturation variables included menarche in girls, testes size in boys, and pubic hair in both sexes. Cardiovascular variables included resting diastolic and systolic blood pressures and heart rate, and the same three variables after recovery from a step test. The boys and girls were 15–16 years of age, and there were equal numbers in each sex/ethnic group. Partial correlations accounting for height (which was affected by ethnicity) and maturation stratified by gender are reported. C was more strongly related to CV risk in boys and girls than the other indices or the body mass index. Least related to CV risk was C/P, correlated only weakly to central skinfold fat. C and WHR are highly related (0.85) yet differ in important respects in both sexes: C is more closely related to body fat (0.62–0.66) and fat mass (0.53–0.77) than the WHR (respective correlations: 0.54–0.55 and 0.43–0.66). Thus, C relates not only to body shape but also to body fat. Indices of central fat such as circumference and skinfold ratios, may “over-correct” for total fatness and thus miss important aspects of risk prediction. Conicity may be a useful indicator of body fat distribution in studies of adolescents. © 1996 Wiley-Liss, Inc.     

Prevalence of parameter indicators of obesity and its relationship with metabolic syndrome in urban Moroccan women

This study aimed to examine the relationship between metabolic syndrome (MS) and different types of obesity in urban Moroccan women. On 213 women aged 25–55 years, Triglycerides (TG), total cholesterol, high‐density lipoprotein cholesterol (HDL‐c), lower‐density lipoprotein cholesterol (LDL‐c), and fasting blood glucose levels were assessed. Body mass index (BMI), waist to hip ratio (WHR), Waist circumference (WC), and blood pressure (BP) were also measured. Globally 36.6% of women were overweight (25 ≤ BMI < 30 m²), 23.9% obese (BMI > 30 m²), 19.7% had WHR > 0.85 and 28.8% had WC ≥ 88 cm. Indicators of obesity increased with age and the prevalence of co‐morbid factors increased with obesity. The women with android obesity (WHR > 0.85) and central obesity (WC ≥ 88 cm) had greater risk compared to those with overweight and general obesity. The prevalence of MS was 17.8% and increased (31.49%) with high BMI and high WHR (50%). MS and its co‐morbidity factors are prevalent among Moroccan women aged 35years and over. The exaggerated influence of obesity in this prevalence suggests that the prevention of obesity could prevent MS and its complications. Am. J. Hum. Biol., 2008. © 2008 Wiley‐Liss, Inc.

Body Composition,Sarcopenia, and Suicidal Ideation in Elderly Koreans: Hallym Aging Study

This study was conducted to assess the relationship between body composition and suicidal ideation among the Korean elderly population (n = 302; ≥ 65 years) who participated in the Hallym Aging Study in 2010. Body composition was measured using dual-energy X-ray absorptiometry, and obesity was measured by the indices of body mass index (BMI), waist circumference (WC), waist-to-hip ratio (WHR), waist-to-height ratio (WHtR), and body fat percentage. Sarcopenia was defined as presence of both low muscle mass and low muscle function. Suicidal ideation was assessed using the Beck Scale for Suicide Ideation. We found no differences in body composition measures between subjects with suicidal ideation and those without. In the logistic regression analyses, there were no significant relationships for suicidal ideation according to body composition measures, including BMI, WC, WHR, WHtR, and body fat percentage in both sexes. After adjusting for age, smoking status, alcohol drinking, regular exercise, medical comorbidities, monthly income, education level, and presence of depressive symptoms, the odds ratio (OR) of suicidal ideation was higher in elderly men with sarcopenia compared to those without, whereas no significant relationships were observed in elderly women (OR 8.28, 95% confidence interval [CI] 1.20–61.34 in men; OR 0.79, 95% CI 0.07–8.43 in women). Sarcopenia is closely associated with an increased risk of suicidal ideation in elderly men.
