(1) Background/objective: the globally discussed current issue is the increasing body weight of the population. This trend is observed in all age categories. Pediatricians and anthropologists use BMI percentile curves to determine the optimal body weight of children, based on which the child is categorized in the category of underweight, normal weight, overweight, or obese. Medical or anthropological examinations also use some methods to determine the amount of body fat. In addition to evaluating amounts of body fat, it is important to assess its distribution. The distribution of fat in the body, especially in terms of disproportionate distribution, is a risk factor for health complications, especially in terms of metabolic and health risk. Part of monitoring children’s growth is also measuring and evaluating circumferential parameters, such as abdominal circumference, gluteal circumference, and waist circumference. This study aimed to define age- and gender-specific reference curves for waist circumference (WC), abdominal circumference (AbC), and gluteal circumference (GC) in Czech children. (2) Methods: data on children’s circumferential parameters were collected via anthropometric measurements. The research sample consisted of 2093 children aged 6–11 years (boys, n = 1008; girls, n = 1085). Only children with parental informed consent were included. The statistical analysis was performed separately by age and gender using SPSS v. 22. Anthropometric data were summarized by mean and standard deviation. The percentile curves of WC, AbC, and GC were calculated (P3, P10, P25, P50, P75, P90, P97) in R 3.4.2 software (R Foundation for Statistical Computing, Vienna, Austria) using the gamlss package. (3) Results and conclusions: the study developed age- and gender-specific percentile curves of WC, AbC, and GC for Czech children aged 6–11 years. All parameters increased with age in both boys and girls. Generally, the boys had higher WC and AbC than did girls, but girls had higher GC than did boys. Female and male median WC percentiles (M) increased from the age of 6. Both girls’ and boys’ median percentiles showed a continuous increase. We found similar trends in the median GC and AbC percentile curves. All percentile curves showed similar trends in both sexes, but the 90th and 97th WC percentiles in boys were exceptions: from the age of 10, they exceeded the values of girls, reaching their peak at the age of 11 followed by a decrease in the case of the 97th percentile and a plateau in the case of the 90th percentile. This study serves as a reference to enrich the methods of evaluation of somatic and medical status in Czech children. Up–to–date percentile curves would be a practical addition to the BMI percentiles for the screening and evaluation of overweight and obese conditions and the related risks of abdominal obesity in the pediatric population.

AbstractObjectivesChildren from different countries and with different ethnic backgrounds have a distinct pattern of central fat deposition. Therefore, it is essential to develop population-specific percentiles of waist circumference (WC), waist-to-height ratio (WHtR) and waist-to-height ratio exponent (WHtR (exp)) for the evaluation of central obesity. The objective of this study was to develop age-and-gender-specific smoothed WC and WHtR percentile curves for the Pakistani children and adolescents aged 2–18 years.MethodsA cross-sectional data-set from a multi-ethnic anthropometric survey was considered. A sample of 10,668 healthy subjects (boys = 51.92%; and girls = 48.08%), aged 2–18 years was studied. Height (cm) and WC (cm) of each subject was measured under standard procedure and WHtR & WHtR (exp) were calculated. Age-and-gender-specific smoothed curves were obtained using the lambda-mu-sigma (LMS) method and compared with percentile curves obtained from different countries.ResultsExcept few early ages, the WC values increased with age in both sexes. Both boys and girls had approximately similar WC during 6–11 years of age and after age of 11, the boys had larger WC than the girls had. For WHtR, the centile curves showed a continuous decrease by 16 years of age and then increased gradually. WHtR of the girls in various ages were having similar or higher than those of the boys. In comparison of WC 50th and 90th percentiles with other countries, it was found that except few ages, the Pakistani children had larger WC than the other reference populations and the results of WHtR were also comparable to the other nations.ConclusionsWe present new reference data of WC, WHtR and WHtR (exp) using a representative sample of the Pakistani children aged 2–18 years. These reference values can be used provisionally for early detection of central obesity and its associated risks in the Pakistani children.

Background: Obesity caused diabetes and cardiovascular disease. Yoga considered three aspects, physic, emotion and mental that helped in obesity therapy.Objective: This research aimed to explain the influence of yoga excercise on body weight, percent of body fat, waist circumference and waist to hip ratio (WHR) in overweight women.Method: This research applied quasi experiment design by using pre-post test with control group design. The subjects of research were 31 women aged 19-25 years old and divided into 2 groups, treatment group and control group. Treatment group was prepared to do yoga in 60 minutes for 10 times during 20 days and given nutrition education, whereas control group was given nutrition education only. Data body weight and percentage of body fat were measured by bioimpedance analysis; waist circumference and WHR were measured by tape measures; food intake were assessed by food recall and food frequency questionnaire. Data were analyzed using paired t-test and independent t-test.Results: There was a significant difference of body weight before and after intervention in both groups. The body weight on treatment group decreased by 0.81 ± 1.29 kg (p<0.05), while the body weight on the control group increased. Percentage of body fat and waist circumference decreased on both of groups, however treatment group decreased more than the control group. WHR no significant on both of groups. Yoga excercise resulted no significant influences on body weight, percentage of body fat, waist circumference and WHR in overweight women (p>0.05). Conclusion: Obesity women with 10 times yoga had no significant influences on body weight, percentage of body fat, waist circumference and WHR.

A metaanalysis was conducted on data from 172 subjects (healthy volunteers and uninfected patients) included in 10 pharmacokinetic studies of fleroxacin after oral administration. The objectives of this analysis were (i) to estimate the typical values of two key pharmacokinetic parameters, clearance over systemic availability (CL/F) and volume of distribution over systemic availability (V/F), after the administration of therapeutic doses and (ii) to study qualitatively and quantitatively the factors which influence the elimination and distribution of fleroxacin. The main pharmacokinetic parameters, CL/F and V/F, were analyzed separately by a standard two-stage approach. The covariates investigated were predicted creatinine clearance (CLCR), age, gender, body surface area, body weight, and lean body weight (LBW). The predicted CL/F and V/F were 83.5 ml/min and 101 liters, respectively, for a typical male subject (CLCR, 70 ml/min; LBW, 54 kg; age, 54 years). Modeling of CL/F indicated that this parameter increases linearly with CLCR, decreases linearly with age, and is 10.8 ml/min lower in females than in males. The best model for V/F showed a linear increase with LBW and a linear decrease with age. V/F was found to be 20.4 liters greater in males than in females. In conclusion, this metaanalysis has shown that CLCR, age, and gender influence the elimination of fleroxacin from the body, whereas V/F is influenced by LBW, age, and gender.

The true prevalence of obesity in childhood is difficult to determine as there is no internationally accepted definition of pathological adiposity in the paediatric age group. Body weight is reasonably well correlated with body fat but is also highly correlated with height, and children of the same weight but different heights can have differing amounts of adiposity. In children the relationship between body mass index (BMI) and body fat varies considerably with age and with pubertal maturation. BMI centile charts using national BMI reference data have now been published in several countries and aid the graphical plotting of serial BMI measurements in individual patients. However, such charts are often based on arbitrary statistical measures and not on biological data related to the risk of later morbidity. Cole et al. developed age- and gender-specific cut-off lines from BMI data derived from six countries, which extrapolate risk from the adult experience to children (1). The International Obesity Task Force (IOTF) has recommended the use of these age- and gender-specific BMI cut-offs (overweight as approximately 91st percentile or greater and obesity as approximately 99th percentile or greater) for the comparison of obesity prevalence in different populations (2). Although there is no accepted definition for severe obesity in childhood, a BMI SD >2.5 (weight off the chart) is often used in specialist centres and the crossing of weight percentile lines upwards is an early indication of the risk of severe obesity.

Abstract Obesity and overweight have been frequently observed in dogs in recent years as in humans. The compositions of fatty acids in the accumulated lipids in tissues of obese animals may have important roles in the process and mechanisms related to the onset of metabolic disorders. The purpose of this study was to evaluate the effects of a vegetarian diet, which contained a higher proportion of unsaturated fatty acids on individual morphometric parameters in spayed dogs. Seven mongrel dogs without ideal body condition scores (average: 7.42) were fed vegetarian dog kibbles and received the daily amount of energy calculated with the following formula: 130 kcal × weight (kg) 0.75. The animals were evaluated on days 0 and 60 in relation to the body measurements, such as: body weight, metabolic body weight, body fat percentage, nape, rib, tail base, chest, and abdomen, using a plicometer. Also determined were the body condition scores (scale from 1—thin to 9—obese), canine body mass index, and their waist circumference. These data were analysed by the Student’s t-test. The body measurement variation of body fat percentage, waist circumference, body condition score and thickness values of the abdomen differed significantly (P < 0.01).

Abstract Metabolic syndrome (MS) is common among children and adolescents. Age- and gender-specific references or age-, gender- and height-specific references were used in pediatric MS definitions. More recently, an increasing number of studies documented that the ratio of waist circumference (WC) to height (WHtR) and blood pressure to height (BPHR) were easy anthropometric indexes for detection of obesity and hypertension in children and adolescents. For these reasons, height-corrected MS definition was proposed. WHtR and BPHR were used as alternatives to WC and BP in the definition of MS. In the present review, we discuss the possibility of the height-corrected MS definition for identifying MS in children.

Androgen-dependent dermopathy, as well as premenstrual syndrome of varying severity in young women, can cause emotional depression, difficulties in social adaptation and even depressive disorders. The aim of the study was to study the safety and efficacy of using a combined oral contraceptive (COC) Dimia® containing 20 μg ethinyl estradiol and 3 mg drospirenone in young women, as well as its therapeutic effects in androgen-dependent dermopathy. Materials and methods. The study included 57 young women aged 23.1±2.2 years with signs of androgen-dependent dermopathy. The evaluation of the change in the character of menstrual bleeding, the anthropometric parameters (body weight, waist circumference and hips), the therapeutic effect of the drug on the symptoms of androgen-dependent dermopathy, as well as the dynamics of arterial pressure, hemoglobin level, serum iron have been studied. The psycho-emotional state was assessed using the SAN questionnaire (well-being-activity-mood). Results. During 6 months of observation, there was no significant change in the body mass index, waist circumference, and hips, and the drug did not affect the blood pressure numbers. Against the background of taking the drug, there was an increase in the parameters of iron metabolism (hemoglobin content, serum iron). After 3 months of taking the contraceptive with drospirenone, the number of patients with a complaint about the abundance of menstruation decreased more than twofold (from 22.8 to 10.5%), and after 6 months of taking the drug no patient noted the profuse nature of menstruation. Before the start of taking COC with drospirenone, 57.9% of women reported painful menstrual bleeding. Against the background of taking the contraceptive within 3 months, this complaint was stopped in all patients. Sufficient efficacy of treatment of androgen dependent dermopathy in young women with the help of a microdosed drospirenone-containing combined oral contraceptive is estimated from the dermatological acne index. The analysis of the SAN questionnaire made it possible to reveal the improvement in the psychoemotional state of patients on the background of taking the drug. The conclusion. The results obtained proved the effectiveness and safety of the microclinized COC Dimia®. The drug has no significant effect on body weight, blood pressure, provides reliable control of the cycle and a decrease in menstrual bleeding, which results in stabilization of iron metabolism in the body. Dimia® is effective in the treatment of androgen-dependent dermopathy and can be recommended to young women for starting contraception.
