Content available remote Assessment of the BMI, WHR and W/Ht in pre- and postmenopausal women
100%
EN
The main goal of this study was to determine whether and how values of the BMI, WHR and W/Ht indicators change in pre- and postmenopausal women. The tested group consisted of 10,216 women aged 25-95 years. Data were collected during the national campaign "Fighting Obesity", organized by Hand-Prod Company between 2000-2002 across Poland, when adult women voluntarily filled in a questionnaire and participated in anthropometric measurements. The BMI, WHR and W/Ht values were calculated based on these measurements. The values of the BMI, WHR and W/Ht change with age. However, in each age group postmenopausal women have higher BMI, WHR and W/Ht than premenopausal women. Thus, the results obtained indicate that hormonal changes occurring in the climacterium period cause an increase in the analyzed index values. The BMI used herein is characterized by high accuracy in indicating obesity. Moreover, the WHR and W/Ht are also used as adiposity indicators, which may be useful in assessment of the risk of disease or death caused by hypertension, cardiac diseases, diabetes, or even cancers. However, they should not be used only in relation to obese women, because even a slight increase in visceral obesity, with body mass within normal limits, may contribute to unfavorable changes in the woman's metabolic profile, which in turn, may present a risk of illness.

Głównym celem niniejszej pracy było określenie czy i w jaki sposób zmieniają się wartości wskaźników BMI, WHR oraz W/Ht u kobiet przed menopauzą i po menopauzie. Badaną grupę stanowiło 10.216 kobiet w wieku 25-95 lat. Dane zebrano podczas ogólnopolskiej akcji "Walczymy z Otyłością", organizowanej przez Firmę Hand-Prod w latach 2000-2002 na terenie całej Polski, podczas której zgłaszające się dorosłe kobiety dobrowolnie wypełniały ankietę, i którym wykonano pomiary wysokości, masy ciała, obwodu pasa oraz bioder. Na podstawie wykonanych pomiarów określono wskaźnik BMI, WHR oraz W/Ht.Niedowagę stwierdzono u 1,0% kobiet. Częstość występowania nadwagi w badanej grupie wynosiła 38,4%, natomiast otyłości 27,9% (ryc. 1 i 2). Prawidłowe wartości (poniżej predysponujących do wystąpienia chorób powiązanych z otyłością) dla WHR stwierdzono u 32% kobiet, zaś dla W/Ht u 22%. Stwierdzono pozytywne korelacje pomiędzy analizowanymi parametrami (BMI-WHR R=0,29, p<0,05; BMI-W/Ht R=0,79, p<0,05; WHR-W/Ht R=0,64, p<0,05). Zaobserwowano, że nawet wśród kobiet o prawidłowej masie ciała niemal połowa charakteryzowała się WHR≥0,8 oraz W/Ht≥05, zaś wśród kobiet z nadwagą oraz otyłych częstości te istotnie rosły (tab. 1).Do obliczenia wieku menopauzy wykorzystano metodę "status quo", która umożliwia wyeliminowanie błędu, jakim obarczone jest badanie retrospektywne. Wykorzystując analizę probitową, określono procent kobiet w każdej grupie wiekowej, które przestały miesiączkować, co najmniej 12 miesięcy przed poddaniem się badaniu. średnia probitowa wieku postmenopauzalnego dla kobiet po menopauzie naturalnej wynosi 51,74 lata (chi2= 6513,59, df =1, p<0,00).Chcąc zbadać, czy i w jaki sposób wraz z menopauzą zmieniają się u kobiet wartości parametrów morfologicznych określonych na podstawie wskaźników: BMI, WHR oraz W/Ht, w pierwszej kolejności przeanalizowano zmiany tych parametrów z wiekiem. W tym celu zastosowano analizę regresji, która wykazała, że wartości wszystkich wskaźników istotnie rosną z wiekiem (tab. 2 i 3). Następnie w celu zaobserwowania zmian wskaźnika BMI w grupach kobiet przed menopauzą i po menopauzie, przeprowadzono analizę wariancji. Uzyskane wyniki wskazują, iż zmiany wartości wskaźnika BMI, WHR oraz W/Ht, w grupach kobiet przed menopauzą i po menopauzie, istotnie się różnią (tab. 4). Kobiety, które nadal miesiączkują mają wskaźniki BMI (wartość testu F=648,62 df=1, p<0,001), WHR (F=164.64 df=1, p<0.001) oraz W/Ht (F=18.24, df=1, p<0.01) niższe niż kobiety, znajdujące się w okresie pomenopauzalnym. Wartości współczynników zmienności wskazują na znaczną zmienność tej cechy, zarówno w grupie kobiet przed menopauzą, jak i po menopauzie. Jednakże w każdej grupie wiekowej kobiety po menopauzie mają wskaźniki BMI, WHR oraz W/Ht wyższe niż kobiety przed menopauzą (ryc. 3-5).Zmiany hormonalne zachodzące w okresie klimakterium powodują wzrost wartości wskaźników BMI, WHR oraz W/Ht. Niezależnie od wieku kalendarzowego menopauza przyczynia się do zmian w rozkładzie tkanki tłuszczowej u kobiet. Wykorzystany w niniejszej pracy wskaźnik BMI charakteryzuje się wysoką dokładnością w predykowaniu otyłości. Wskaźniki WHR oraz W/Ht, jako indykatory otłuszczenia, mogą być użyteczne do oceny ryzyka zachorowania lub śmierci z powodu nadciśnienia, chorób serca, cukrzycy a nawet nowotworów. Wskaźniki te powinny być wykorzystywane nie tylko w odniesieniu do kobiet otyłych, ponieważ nawet niewielki wzrost otyłości wisceralnej, przy masie ciała pozostającej w normie, może przyczyniać się do niesprzyjających zmian profilu metabolicznego kobiety, a tym samym stanowić ryzyko wystąpienia chorób.

We examined the association between overweight/gender and skipping breakfast among adolescent students in Tehran city using a cross-sectional study and a multistage random sampling method. All educational zones in Tehran city were covered during the educational year of 2000–01. In total, 2321 students aged 11–16 years (1068 male; 1263 female) participated in the study. Weight and height were measured and body mass index (BMI; kg/m2) was calculated. Overweight, pre-obesity and obesity were defined as BMI ≥ 85th, 85th to 95th, and ≥ 95th percentile of age-sex-specific BMI reference values, respectively. Self-reported frequency of breakfast consumption was categorized as usual/always, often, and rarely/never (5–7, 2–4 and 0–1 times/wk, respectively). Student’s t and Chi-square tests were employed to analyze the data. Statistical inferences were made at α = 0.05. In boys and girls, the mean ± standard deviation of BMI was 19.8 ± 4.0 and 20.6 ± 4.1 kg/m2, the 18.8% and 23.1% were overweight, and 7.3% and 8.3% were obese, respectively. There was a significant difference in the frequency of breakfast consumption between obese and normal male students (P < 0.001). Differences between pre-obese and normal, and obese and normal female students were also significant (P < 0.002 and P < 0.001, respectively). A significant difference was found in the frequency of breakfast consumption between male and female adolescents in all three categories (P < 0.001). These results suggest that obese and female adolescents are more likely to skip breakfast than their normal and male peers and are therefore at higher risk for growth deficits and low educational performance. Preventive/educational programs are urgently needed in this age group.

Introduction. In recent years there has been a significant increase in the prevalence of overweight and obesity in humans. It turns out that the problem is not limited to adults; excessive body weight is occurring in children more often. Aim. The main purpose of this work was to determine the prevalence of overweight and obesity in preschool children from the Rzeszów district, and to determine risk factors for occurrence. Materials and survey method. The study was conducted among 200 preschool children (3 - 6 years of age) from the Rzeszów poviat area. Measurements of height, weight, and determination of BMI were performed and these values are standardized according to the WHO centile grids appropriate for each age group. Survey results. Normal weight was observed in 58% of the respondents, 11% were overweight, and 10.5% were obese, whereas 20.5% of children had undernourishment. Obese children were the largest group among 6-year-olds. Among 4 year old children, abnormal body weight were more frequent in boys. On the other hand, in children aged 5 years, undernourishment or overweight was found more frequently in girls. Conclusions. The study did not confirm a significant relationship between gender, place of residence and socio-economic situation of respondents, and the prevalence of overweight or obesity. The results of this study indicate that the problem of excessive body weight refers to the increasing number of children.

The aim of the present study was to assess the adolescents’ weight status and weight status perception and also to examine the influence of weight status misperception on weight related behaviors. The survey was conducted in 2014 in population consisting of 125 adolescents aged 15 years living in Sopot, in northern Poland. An anonymous questionnaire contained questions concerning body mass and height and questions on weight status perception and previous weight loss attempts. The study found a high prevalence of excessive body mass among adolescents. Overestimation of weight status had stronger influence on the number of weight loss attempts than underestimation and accurate perception. The study also revealed significant differences between boys and girls in accuracy of weight status perception that could be caused by gender-based stereotypes related to body shape.

Overweight and obesity constitute a serious social problem. They are considered hazards of developed countries. Overweight and obesity affect both adults and children. Numerous researches on the negative impact of obesity on the condition of oral cavity have been conducted. The purpose of this paper is to provide a review of the most recent data published and noted in PubMed database between 2007 and 2014, on the association between overweight and obesity and oral diseases, including caries and periodontal diseases, as well as to discuss their mechanisms. The majority of studies discussed in this paper demonstrate the existence of an association between obesity and the health of the oral cavity. An association between overweight and obesity expressed as various anthropometric indices, and oral cavity conditions should be the subject of further prospective studies.

Background: The analysis presented in this paper aimed to identify trends in the prevalence of the two extremes of body fat disorders over a period of 20 years (1979-1999) and to form a comparative basis for further studies of physical development of the youth of the Pomerania region.Material/Methods: The study population consisted of 23,854 boys and girls aged 7 to 18 years attending schools in rural and urban areas in the Pomerania administrative region. An overweight and underweight population was identified based on the body mass index (BMI) according to WHO, CDC and the Mother and Child Institute recommendations. The following threshold values were adopted: BMI≤ 5th centile for underweight, BMI between 5th and 15th centile for slimness, between 85th and 95th centile for overweight, and BMI≥ 95th centile for obesity).Results: The highest percentage of boys with a BMI between the 85th and 95th centile was seen in 1999, with figures of 8.7% among younger boys and 7.9% among older boys. This represented respective increases of 3.2 and 2.2 percentage points over 1979 data. The proportion of overweight boys (7 - 18 years) increased from 5.6% in 1979 to 7.4% in 1989 and 8.4% in 1999. The differences between these percentages (among both younger and older boys) in the study period (1979-1999) were statistically significant. Comparing 1989 and 1999, statistically significant differences were only identified among younger boys, and between 1979 and 1989 differences were statistically significant among older boys and for the entire study population.Conclusions: The 20-year period was marked by increasing prevalence of overweight among the boys and girls. Awareness of the consequences of developmental dysharmonies in the form of over- and underweight demands that these trends be further monitored.

Introduction. Obesity is a significant health and economic problem, both for the patient and the health care system. An essential element in the prevention and treatment of each disease is the engagement of all groups of healthcare professionals. In our study, we performed an analysis of the real world data, obtained from a survey of the medical and socioeconomic problems associated with overweight and obesity. We aimed to identify the pharmacist’s role in the management of overweight and obese patients, including their individualized education in an outpatient setting. Material and methods. The study material consisted of responses obtained from a specially designed questionnaire. Our findings indicate that the study patients had easy access to a pharmacist’s professional knowledge, relevant to comprehensive treatment of obesity. In addition, our data indicates a lack of patient knowledge of a healthy lifestyle and an inability to implement such knowledge in practice. Results. The community pharmacist should actively provide support to patients with obesity (including the primary obesity and those who want to lose excessive body mass for health-related and also for aesthetic reasons) and the management of their weight. The results of our study should be considered as an introduction to further research to facilitate the understanding of problems and expectations of patients and to prepare pharmacists to perform pharmaceutical care (PC) in this regard. Conclusion. One of the potential options to protect society against the obesity epidemic is an education about the risks inherent to obesity and promotion of a healthy lifestyle.

The quality of life is a multidimensional notion. When studying it, one should take the physical, the psychological, the social, and the professional aspects into consid eration. Among them, the notion of the influence of obesity, understood as a modern -age disease, relates the quality of life to the notion of health, in the aspect of physical activity. The aim of the study carried out, was to determine the relationship be tween obesity in 18 -25 year - olds, and their physical activity, as well as the quality of their lives. The study was carried out by means a WHOQOL - BREF, and IPAQ survey questionnaires carried out on a group of 100 participants. The control group included pe ople whose BMI was within the norm, whereas the study group comprised people whose BMI was over 25. The results of the study have shown obesity to have a statistically significant negative impact on the quality of life in the physical, and mental domains, and as far as the general perception of health was concerned. In the study group, the mean weekly energy expenditure, was lower than in the control group. The physical activity of the obese, includes, mainly, activities based on light effort, and to a less er extent, those based on moderate effort. A comparative analysis has shown the level of physical activity to be significantly lower in obese women, in each type of physical effort, except light effort. This difference does not exist between the study, and control groups of men.

Objectives. Excess weight and obesity in children are associated with psychosocial complications and have the attributes of psychosomatic illness. The research followed on from Czech and foreign publications about families with overweight and obese children, about the peculiarities of cognitive and social development, and about the psychosocial circumstances that accompany this section of the populace. This paper maps out the existing state of knowledge in the above areas, too. The aim of the research was to verify findings of foreign studies relating to the experiences of overweight preschool children with prejudices about themselves by their peers also among the Czech population. Similar problem was also researched in terms of performance of these children in two cognitive tests and their estimates by adults. Methods. The study compared the results of the Pre-school Children Knowledge Test and of the Urban’s Figural Test of Creative Thinking in the group of children with overweight (N=52; BMI percentile ranged 92-95; converted to BMI values M = 18.18; SD = 0.36; age 4-6; M=4.62; SD=0.49), their estimates by parents and kindergarten teachers and in the control group of children with normal weight (N=46; BMI percentile ranged 11-72; converted to BMI values M = 15.38; SD = 0.52; age 4-6; M=4.53; SD=0.58). Observation of Social Expressions of both groups of children in a free play situation was performed, too. Results of cognitive tests, estimates and observations were evaluated in the mutual context. Processing the data. We carried out a descriptive analysis of all the variables. The standard significance level used in the statistical testing was ?=0.05. Multiple linear regression was performed in the form of a so-called generalized linear model (GLM) in order to underpin the influence of the quantitative variables of social behaviour and the categorical variables of the child’s weight on the difference between the real results of the cognitive tests and the results as estimated by the children’s mothers, fathers and teachers. From the original, complete set of regressors we gradually eliminated those which proved to be statistically insignificant. Results. In terms of the level of performance of both groups of children in both cognitive tests there were found no significant differences, while observed social expressions showed the one. Estimates of the performance of both groups of children in the two sets by adults were mostly tended towards overestimation. After customizing some of these results to social variables and in terms of estimates by adults the weight band lost in some cases its importance. Conclucions. The number of child respondents was affected by real number of overweight pre-school children in the Zlín region (see Discussion). The link between children’s weight and their performance as estimated by adults may be influenced by social and possibly by other types of variables. The difference in the social behaviour of the two sets of pre-school age children may be an indication of nascent differences in their psychosocial development. Several studies have confirmed that the relationships between problems with preschool peers have tendency to repeat in older peer groups and in some cases were confirmed relations with psychiatric disorders in adulthood, too. v

W e compared the effects of 16-week-training on rest metabolic rate, aerobic power, and body fat, and the post-exercise effects upon rest oxygen uptake and respiratory exchange ratio in overweight middle-aged females. Twenty nine overweight women (BMI 29.9 ± 1.2 kg*m-²) participated in training (3 days a week). The subjects were divided onto groups of aerobic (AT) and strength (ST) training. The results showed that the total body mass decrease and VO2 max increase did not differ in both groups. Decrease in waist circumference after 16 weeks was higher in the ST group. In the ST group fat-free mass increased during the first 8 weeks. Rest metabolic rate was increased significantly at 16th week compared to initial value in ST group only. Significant increase in post-exercise resting VO2 and respiratory exchange ratio at 12 and 36 h was observed after the strength training session only. Increase in rest metabolic rate and post-exercise rest energy expenditure occurred after strength training but not after aerobic training despite the similar increase in aerobic power. The effect of 8-16 weeks of strength training on body mass decrease was higher in comparison to aerobic training.

The occurrence of overweight, obesity and physical activity (PA) belongs to major factors influencing health. However, information on the longitudinal development of PA in Europe has been, up until now, insufficient. The aim of the study was to describe the changes in PA, sedentary behavior and BMI in the inhabitants of the Liberec region during the surveybetween 2002 - 2009. The data were obtained in 2002-2004 using the short version of the IPAQ questionnaire, in 2005-2009 using the long version of the IPAQ. The sample of participants comprised 957 males and 1066 females aged 25-60 years. A significant decrease in sitting accounting for minutes on working days has been recorded both in men and women. A significant increase of PA both in men and women was reported, however the interpretation of the increase needs to be done cautiously due to the application of the short and long version of the IPAQ. Regarding PA intensity, men show more PA in total than women, which can be explained mainly by the differences in vigorous PA. Women show significantly lower values of BMI in all years in which surveys were conducted than men (p<0.001). Based on self-reported data, we have recorded an increase in the number of overweight and obese people. Time spent sitting on working days has had a tendency to decrease, yet a negative trend in the decrease in self-reported total PA has not been confirmed. Despite the fact that there has been an increase in self-reported PA, no decrease in BMI was registered.

Obesity is of significant and growing concern among Australian Aboriginal children, and is linked to patterns of child growth. The aim of this paper is to show diverse patterns of growth and obesity emergence among Australian Aboriginal children using historical anthropometric data. Child growth in height, weight and body mass index (BMI) is reanalysed for children aged 2 to 19 years in Australian Aboriginal communities spanning two distinct time periods (the 1950s and 1960s; and the 1990s and 2000s) and six different geographical locations: Yuendumu, Haast’s Bluff, Beswick, Kalumburu, Gerard, and Raukkan. Comparisons of stature and BMI between the earlier and later years of measurement were made, and the proportion of children classified as overweight or obese by the International Obesity Task Force criteria estimated, to allow international comparison. Aboriginal children in the 1990s and 2000s were heavier, with higher BMI than those in the 1950s and 1960s, differences in height being less marked. While no children were classified as overweight or obese in the earlier period, 15% of males and 3% of females were classified so in the later period. The data suggests that the period of onset of the epidemic of overweight and obesity among rural Australian Aboriginal children was likely to have been between the 1960s and 1980s.

Introduction: The prevalence of obesity is increasing worldwide, especially among youth. The main cause of obesity in young people is a combination of excessive caloric intake and reduced physical activity. In addition to individual dietary and physical activity behaviors, genetic predisposition, socioeconomic and environmental factors, and comorbidities may contribute to obesity. Aim: The study aims to examine and compare the factors determining food preferences and habits as well as the occurrence of overweight and obesity among teenagers and youth in Poland and Belarus. Material and methods: An anonymous questionnaire consisting of 58 questions based on the Eating Behavior Questionnaire (QEB) was used. Responses were received from 700 young people from Poland and 690 from Belarus, some of whom were rejected. The data was collected in May and June 2021 and analyzed in the Statistica program (statistically significant results at p<0.05). The research was financed by a grant from the Polish National Agency for Academic Exchange. Results: The study group was divided into four groups in terms of age and nationality: Poles <20 years old (428 people), Belarusians <20 years old (222 people), Poles 20-29 years old (210 people), and Belarusians 20-29 years old (295 people ). The correct BMI had 66.7%, 74.3%, 70.7%, and 71.2% of the respondents, respectively (p=0.057; p=0.888). In both age groups, in the Mann-Whitney U test, there are significant differences in the number of meals per day (p<0.001) - Poles eat 4 or 5 meals a day more often, and Belarusians 3. In the chi-square test, both age groups showed a significant statistical difference (p<0.001) in the question about eating breakfast every day - Poles eat breakfast more often than Belarusians. The Mann-Whitney U test showed no differences in sleep duration between the respondents from both countries (p=0.453; p=0.905). Conclusions: The results of the research indicate a strong need to implement educational programs to raise the awareness among young people about healthy eating. Obesity, skipping breakfast, too few meals during the day, and their incorrect composition indicate the direction of pro-health policy, which will be conducive to making the right food choices for youth.

ody Attitude Test (BAT, Van Coppenolle, Probst et al., 1990) is a widely used measurement. Our main goal was to support the original factorial structure of BAT in Hungarian normal weight and overweight/obese female samples. Research design was a cross-sectional, questionnaire study. Research participants were normal weight female students, and female participants of a lifestyle modification program. Measures were Body Attitude Test, Human Figure Drawings Test, Rosenberg Self-Esteem Scale, and Trait Anxiety Inventory. The confirmatory factor analysis verified the original structure of BAT in our samples. Internal consistency, test–retest reliability and construct validity were satisfactory.

Monitoring data analysis forms a central basis for the assessment of the prevalence and development of overweight and obesity in children and adolescents, thus identifying a potential need for action and adopting preventive measures. Based on data of 5‘515 children and adolescents aged between 4 and 14, this article presents a current trend analysis for Liechtenstein for in the period between 2004 and 2018. This study is based on cross-sectional data from health screening examinations supervised by the national Office of Public Health. The Body Mass Index (BMI) was calculated from anthropometric measurements and classified with reference to the age and gender-specific cut-off criteria of the International Obesity Task Force (IOTF). Across the examined age groups, 15.6% of all children and adolescents in Liechtenstein are currently considered to be overweight or obese. This is a similiar prevalence as in neighbouring regions and shows a stable development over the 15-year monitoring period.

Artykuł prezentuje wyniki analizy dwóch wybranych roczników czasopisma „Super Linia”: z 1995 i 2015 roku. Poddano je analizie ilościowej i jakościowej, skupiając się szczególnie na tym, jakie zagadnienia dotyczące otyłości poruszane były w wybranych rocznikach, oraz jakie znaczenia nadawano otyłości, pisząc o niej w trzech kontekstach: społecznym, estetycznym i medycznym. Porównanie wykazało, że zestaw zagadnień poruszanych na łamach czasopisma nie uległ znaczącym przemianom w wydaniach z 2015 roku w porównaniu z tymi z 1995. Natomiast znaczenia nadawane otyłości w największym stopniu zmieniły się w obszarze społecznego aspektu cielesności osób z nadwagą.

The article presents the results of the contents analysis of a magazine addressed to people potentially interested in reduction of their body weight. The subject of the analysis were two annual editions of “Super Linia” magazine, issued in 1995 and 2015. The methods of quantitative and qualitative content analyses were used. The main focus of the analyses were the kinds of issues raised in the two chosen annual editions as well as the meanings assigned to obesity in three chosen contexts: social, aesthetic and medical. The comparison of the two annual editions has shown, that the range of issues raised in the magazine has not changed significantly in 2015 in comparison to 1995. The meanings assigned to obesity have changed to the greatest extent when presenting obesity in the social context.

Purpose: The purpose of this paper is to highlight a fundamental gap in the economic research on obesity - the demand for unnecessary weight gain preventive goods. Such research is important as it will provide understanding of people’s preventive behaviours and for that matter inform policies and practices with regards to influencing people’s uptake of obesity preventive goods. Materials and methods: Using MeSH and PICO approaches, a search strategy was developed to search for relevant articles in a number of academic and scientific journal repositories including PubMed Central, EconLit, Medline, Medscape and relevant (economic) journals’ archives. The search strategy combined terms/phrases to look for publications. Results: A total of 1351 potentially relevant articles (titles and abstracts) were reviewed. No publications could be found that concerned people’s preventive behaviours in terms of demand with respect to obesity preventive goods. Only one article which was not specific to obesity looked into people’s preventive behaviours using an economic model. Conclusions: Despite the huge economic and health burden of obesity, participations in activities deemed supportive to weight gain prevention are dismal. It must not therefore be assumed that there will be demand for all effective weight preventive goods/services. As a result of the complex nature of the condition, the demand for obesity preventive goods requires understanding of the complex factors which influence individual decisions. The behavioural economic perspective could help to increase understanding of the preferences of people as it examines how decisions are made by individuals in complex socio-economic and socio-cultural circumstances and financial constraints involving trade-offs.

There is no data on the prevalence of overweight and obesity in young Syrian boys. Therefore, the present study aimed to provide baseline and reference data on the prevalence of overweight and obesity among young Syrian boys using skin-fold thickness measurements and deuterium dilution (DD) as a reference method. The sample of 2470 healthy Syrian 18- to 19-year-old boys were enrolled in this study. SFTs were measured at the biceps (B), triceps (T), subscapular (SI) and suprailiac locations (SS) were done and validated using the DD technique as a reference method. Receiver operating characteristics (ROC) curve was drawn to determine appropriate cut-off points of the Σ2 limb SFT (T+B), Σ2 trunk SFT (SI+SS), Σ4 SFT (T+B+SI+SS) and Log Σ4 SFT for defining overweight and obesity. The overall prevalence of overweight and obesity in young Syrian boys, based on biceps SFT, triceps SFT, subscapular SFT, suprailiac SFT, Σ2 limb SFT, Σ2 trunk SFT, Σ4 SFT, logarithm Σ4 SFT, and DDT were 35.3%, 32%, 31.6%, 14.8%, 32.9%, 26.6%, 28.1%, 24.1%, 46.5%, respectively. Strongly positive correlation was found between SFT and total body fat in adolescents. For diagnosing overweight on the basis of Σ2 limb SFT, Σ2 trunk SFT, Σ4 SFT and logarithm Σ4 SFT, we propose the following cut-off points: 17.25 mm, 23.50 mm, 39.25 mm and 1.60, respectively. To predict obesity, Σ2 limb SFT, Σ2 trunk SFT, Σ4 SFT and logarithm Σ4 SFT threshold were increased to 23.25 mm, 32.50 mm, 55.25 and 1.75, respectively. Basing on SFT clearly leads to underestimates of the prevalence of weight problems among young boys. SFT measurement screen missed 11.2 to 31.7% of overall overweight and obesity cases.
