J45: In Search of a Definition of Childhood Obesity

Childhood obesity is manifested when there develops a discrepancy between intake and output of energy, disturbing the original steady state and formation of a fresh steady state at a higher level, resulting in increased body-fat storage. There needs to be a delicate balance established between tissue synthesis (height gain) and fat storage (mass gain) in order to prevent obesity. Various definitions of childhood obesity have been proposed. During 1995-2001, Poskitt, representing European Childhood Obesity Group (ECOG), tried to deal with this issue. In a 1995 paper, she expressed concern over lack of childhood-obesity definition. In 2000, she mentioned that the concept of relative body-mass index (BMI) had been generally accepted. In 2001, she observed that BMI could not be considered as offering the ‘best’ definition, although it might be ‘useful’ and ‘practical’. In 2000 Cole and co-workers linked childhood obesity to adult-obesity-cutoff point (BMI 30 kg/m2). In a 2010 paper, Flegal and co-workers gave 3 BMI-for-age categories: ‘normal’, ‘intermediate’ and ‘high’. The first one most unlikely, whereas the last one most likely, to have high adiposity. In a 2011 paper, Rolland-Cachera and co-workers, on behalf of ECOG, defined 3 cutoffs of BMI, constituting four ranges: ‘thin’, ‘normal’, ‘overweight’ and ‘obese’. During the same year, Zhao and Grant defined obesity as excess of body fat. In a 2015 paper, Al-Gindan and co-workers expressed the opinion that most national-survey analyses equating BMI in excess of 30 kg/m2 with ‘obesity’ led to survey-data misinterpretation. This paper puts forward the point-of-view that ‘overweight’ must be differentiated from ‘overfat’. One needs a definition based, solely, on measurement of mass, not measurement of fat, which is difficult to obtain in a reproducible manner. Childhood obesity has been defined as the condition in which a youngster is required to shed off net mass at the end of 6-month period as compared to current mass based on ‘Growth-and-Obesity Vector-Roadmap’ recommendations. In this work, ‘BMI-based-optimal mass’ is compared with ‘height-percentile-based-optimal mass’ and mathematical relationship is proposed for losing net mass within the next 6 months.

J44: Pedagogical Challenges and Opportunities in Sport and Anthromathematics
Work done at: UNIVERSITY OF KARACHI, University Road, Karachi 75270, Pakistan
Kamal SA, Journal of Education and Research, 4, 2016, 1-30

This paper describes pedagogical challenges and opportunities existing in ‘Program of Sport and Anthromathematics’. Anthromathematics is the mathematics of human body sizes, forms, shapes and proportions, which was, formally, launched on March 22, 2010. The scheme of studies consists of formal teaching, examinations (exploring correctness of concepts and learning of techniques) and projects (non-formal development of skills). Formal teaching is based on problem-solving approach. Classroom-problem solving prepares the student to laboratory-problem solving, which, in turn, is a precursor to field-study- and industrial-problem solving. Quizzes and examinations are designed with a changed layout, SOPs prepared for invigilators and grading system simplified to reduce time for checking a script to around 4 minutes.  Projects train the students in research-proposal preparation, planning of study, conduct of study, analysis of data using mathematical-statistical techniques and interpretation of results. The anthropometric measurements (height, mass, mid-upper-arm circumference) obtained during the conduct of project offer a wealth of learning opportunities in various disciplines — biology, chemistry, engineering, health and safety, mathematics, physics and Quranic studies. The goal is to change student’s perspective and attitude towards the subject at the same time refining concepts and perfecting techniques. Full Text PDF

C137: Streamlining Various Definitions of Childhood Obesity

Work done at: UNIVERSITY OF KARACHI, University Road, Karachi 75270, Pakistan

Obesity has become a universal problem among children. Childhood obesity may be connected to grave psychological, physical and social consequences. First lady of United States, Her Excellency, Michelle Obama declared childhood obesity an epidemic for her country. Obesity develops when there exists a discrepancy between intake and output of energy, disturbing the original steady state and formation of a fresh steady state at a higher level, resulting in increased body-fat storage. In a 2011 work, the author described steady state as a situation employing transfer of energy at a uniform rate (energy-transfer perspective). This is a condition in which probability of occupation is not same in different states; however, it does not vary with time (probability-of-occupation perspective).  The delicate balance between tissue synthesis (gain of height) and fat storage (obesity), if mathematically modeled, may prevent obesity. According to Poskitt (1995), representing ECOG, lack of childhood-obesity definition has been a matter of concern for the group. In 2000 she mentioned that the concept of relative BMI had been generally accepted despite considerable imprecision in defining obesity. In 2001 she stated that BMI could not be considered as offering the ‘best’ definition, although it might be ‘useful’ and ‘practical’ for epidemiological, clinical and population-research purposes. She, further, added that work on definition was essential and needed continuing reassessment. Cole et al. (2000) defined childhood obesity based on pooled-international data and linked to adult-obesity-cutoff point of BMI to be 30 kg/m2. Flegal et al. (2010) divided BMI-for-age categories into three ranges: ‘normal’, ‘inter-mediate’ and ‘high’. The first one most unlikely, whereas the last one most likely, to have high adiposity. Rolland-Cachera et al. (2011), on behalf of ECOG, defined three main cutoffs of BMI, constituting four ranges: ‘thin’, ‘normal’, ‘overweight’ and ‘obese’. Zhao and Grant (2011) observed that obesity might be defined as excess of body fat. Al-Gindan et al. (2015) are of the opinion that most national-survey analyses equating BMI in excess of 30 kg/m2 with ‘obesity’ lead to survey-data misinterpretation. The author is of the opinion that ‘overweight’ (classified based on measurement of ‘net mass’ — mass obtained without any clothing) needs to be distinguished from ‘over-fat’ (classified based on measurement of skinfolds as well as waist and hip circumferences). One needs a definition based, solely, on measurement of mass, not measurement of fat, which is difficult to obtain in a reproducible manner. Staring from this year, mass can be recorded to least count of 0.005 kg in SF-Growth-and-Imaging Laboratory. Kamal and Razzaq (2014) investigated reproducibility of mass measurement to least count of 0.01 kg. The author defines childhood obesity as the condition in which a youngster is required to shed off net mass at the end of 6-month period as compared to current mass based on ‘Growth-and-Obesity Vector-Roadmap’ recommendations. In a forthcoming paper, ‘In Search of a Definition of Childhood Obesity’, the author intends to compare ‘BMI-based-optimal mass’ with ‘height-percentile-based-optimal mass’ and give mathematical relationship for losing net mass within 6 months.
