An Analysis of the Medical Costs of Obesity for Fifth Graders in California and Texas

International Journal of Exercise Science 9(1): 26-33, 2016. The prevalence of childhood obesity in the United States increased more than three-fold from 1976 – 1980 to 2007 – 2008. The Presidential Youth Fitness Program’s FitnessGram® is the current method recommended by the President’s Council on Fitness, Sports & Nutrition for assessing health-related fitness factors, including body composition. FitnessGram® data from California and Texas, the two most populous states, over a three-year time span indicate that more than one-third of fifth grade students, typically ten-year-olds, are obese. Previous studies report that an obese ten-year-old child who remains obese into adulthood will incur elevated direct medical costs beyond his or her normal-weight peers over a lifetime. The recommended elevated cost estimates are approximately $12,660 when comparing against a normal-weight child who gains weight as an adult and approximately$19,000 compared to a child who remains at normal weight as an adult. By applying these figures to FitnessGram® results from California and Texas, each group of fifth grade students in each of the two states will incur between $1.4 and$3.0 billion in direct medical costs over a lifetime. When the percentage of obese fifth graders is extrapolated to the rest of the United States’ 4 million ten-year-olds, this results in more than $17 billion (accounting for adulthood weight gain) or$25 billion (not accounting for adulthood weight gain) in added direct lifetime medical costs attributable to obesity for this single-year age cohort. This information should be used to influence spending decisions and resource allocation to obesity reduction and prevention efforts

Elevated Medical Costs for Obese Fifth Graders in California and Texas

Finkelstein et al. (2014) estimated that an obese ten-year-old, typically in the fifth grade, will incur between $12,660 and$19,630 in direct medical costs beyond those of a normal-weight ten-year-old over a lifetime. PURPOSE: The purpose was to estimate the lifetime direct medical costs attributable to obesity for fifth graders in the two most populous states, Texas and California. METHODS: Body composition data from the Presidential Youth Fitness Program’s FITNESSGRAM® administered in California and Texas each school year from 2010 – 2011 to 2012 – 2013 were used. Data included information on 447,619 – 456,409 fifth graders each year in California and 296,887 – 337,514 fifth graders in Texas. The number and percentage of students in each of the FITNESSGRAM® body composition categories was calculated and those in the Needs Improvement – High Risk (NI – HR) were used for cost estimation. The number of students in the NI – HR category for each year in each state was multiplied by the recommended cost estimate of $19,000 to project the elevated lifetime medical costs attributable to obesity for each group of fifth graders in each state. RESULTS: More than 33$3 billion for each group of fifth graders in California and more than $2 billion for each group of fifth graders in Texas. CONCLUSIONS: When the percentage of obese fifth graders is extrapolated to the entire United States’ 4 million 10-year-olds, this results in more than$25 billion in elevated direct lifetime medical costs attributable to obesity for this 1-year age cohort. These estimates are for obesity and do not include the additional costs associated with overweight (i.e., FITNESSGRAM® Needs Improvement – Some Risk category). This information should be used to influence spending decisions and resource allocation to obesity reduction and prevention efforts

Meeting USDHHS Physical Activity Guidelines and Health Outcomes

International Journal of Exercise Science 10(1): 121-127, 2017 Current public health physical activity (PA) guidelines suggest ≥500 METmin/week of PA, with additional benefits beyond 1000 METmin/week (i.e., a dose response). Revised U.S. PA guidelines are scheduled for 2018. The purpose was to relate health markers (blood pressure, percent fat, BMI, blood glucose, cholesterol, and cardiorespiratory fitness) to verify the dose response for PA guidelines revision. 505 non-smoking participants self-reported PA behaviors and completed medical screening. MANCOVA controlling for age and gender determined the relation between health markers and PA. MANCOVA indicated significantly (P\u3c.001) different health markers of percent fat, BMI, glucose, and treadmill time as a function of PA. Post-hoc Helmert contrasts (1] \u3c500 METmin/week vs. ≥500 METmin/week and 2] 500 to \u3c1000 METmin/week vs. ≥1000 METmin/week) indicated that meeting the PA guidelines was associated with better health markers and higher cardiorespiratory fitness. Effect sizes were greater for contrast 1 than for contrast 2, suggesting a plateauing effect. Revised public health guidelines should consider achievement of ≥500 METmin/week to be most important, with additional modest gain thereafter. Revised PA guidelines should stress the importance of achieving 500-1000 METmin/week

Muscular Fitness and All-Cause Mortality: Prospective Observations

Background: The beneficial effects of cardiorespiratory fitness on mortality are well known; however, the relation of muscular fitness, specifically muscular strength and endurance, to mortality risk has not been thoroughly examined. The purpose of the current study is to determine if a dose-response relation exists between muscular fitness and mortality after controlling for factors such as age and cardiorespiratory fitness. Methods: The study included 9105 men and women, 20-82 years of age, in the Aerobics Center Longitudinal Study who have completed at least one medical examination at the Cooper Clinic in Dallas, TX between 1981 and 1989. The exam included a muscular fitness assessment, based on 1-min sit-up and 1-repetition maximal leg and bench press scores, and a maximal treadmill test. We conducted mortality follow-up through 1996 primarily using the National Death Index, with a total follow-up of 106,046 person-years. All-cause mortality rates were examined across low, moderate, and high muscular fitness strata. Results: Mortality was confirmed in 194 of 9105 participants (2.1%). The age- and sex-adjusted mortality rate of those in the lowest muscular fitness category was higher than that of those in the moderate fitness category (26.8 v. 15.3 per 10,000 persons-years, respectively). Those in the high fitness category had a mortality rate of 20.6 per 10,000 persons-years. The moderate and high muscular fitness groups had relative risks of 0.64 (95% CI = 0.44-0.93) and 0.80 (95% CI = 0.49-1.31), adjusting for age, health status, body mass index, cigarette smoking, and cardiorespiratory fitness when compared with the low muscular fitness group. Conclusions: Mortality rates were lower for individuals with moderate/high muscular fitness compared to individuals with low muscular fitness. These findings warrant further research to confirm the apparent threshold effect between low and moderate/high muscular fitness and all-cause mortality

The fate of the homoctenids (Tentaculitoidea) during the Frasnian-Famennian mass extinction (Late Devonian)

The homoctenids (Tentaculitoidea) are small, conical-shelled marine animals which are amongst the most abundant and widespread of all Late Devonian fossils. They were a principal casualty of the Frasnian-Famennian (F-F, Late Devonian) mass extinction, and thus provide an insight into the extinction dynamics. Despite their abundance during the Late Devonian, they have been largely neglected by extinction studies. A number of Frasnian-Famennian boundary sections have been studied, in Poland, Germany, France, and the United States. These sections have yielded homoctenids, which allow precise recognition of the timing of the mass extinction. It is clear that the homoctenids almost disappear from the fossil record during the latest Frasnian “Upper Kellwasser Event”. The coincident extinction of this pelagic group, and the widespread development of intense marine anoxia within the water column, provides a causal link between anoxia and the F-F extinction. Most notable is the sudden demise of a group, which had been present in rock-forming densities, during this anoxic event. One new species, belonging to Homoctenus is described, but is not formally named here

Citrulline metabolism in normal and citrullinemic human lymphocyte lines

Citrullinemia is one of the five aminoacidurias associated with the Krebs-Henseleit urea cycle. A long-term lymphocyte line (UM-21) derived from a patient with this disease and nine of ten clones of this line were found to have no activity for the enzyme argininosuccinate synthetase (AS), as demonstrated by their inability to grow in medium in which citrulline had been substituted for arginine, by their inability to incorporate arginine-C 14 derived from citrulline-C 14 into cellular protein, and by direct enzyme assay. One clone had normal or nearly normal argininosuccinate synthetase activity, as demonstrated by the same criteria. Nutritional “variants” able to grow logarithmically in medium containing citrulline were isolated from UM-21 and three clones. The apparent K m s of AS for citrulline in UM-21, the ten clones, the variant lines, and a normal line were measured and fell into three groups: AS in UM-21 and nine clones had no measurable apparent K m for citrulline; AS in the variant cells had apparent K m s for citrulline of approximately 20 m m ; and AS in the normal cell line and one clone had apparent K m s for citrulline of 0.2 m m . The data suggest that the defect in the citrullinemic cell lines is due to a mutation in the structural gene coding for argininosuccinate synthetase.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/44122/1/10528_2004_Article_BF00485789.pd

Children’s coping with in vivo peer rejection: An experimental investigation

We examined children's behavioral coping in response to an in vivo peer rejection manipulation. Participants (N=186) ranging between 10 and 13 years of age, played a computer game based on the television show Survivor and were randomized to either peer rejection (i.e., being voted out of the game) or non-rejection control. During a five-min. post-feedback waiting period children's use of several behavioral coping strategies was assessed. Rejection elicited a marked shift toward more negative affect, but higher levels of perceived social competence attenuated the negative mood shift. Children higher in depressive symptoms were more likely to engage in passive and avoidant coping behavior. Types of coping were largely unaffected by gender and perceived social competence. Implications are discussed. © 2006 Springer Science+Business Media, LLC
