Obesity Status (obesity + status)
Selected AbstractsOverweight and obesity in preadolescent children and their parents in Cyprus: prevalence and associated socio-demographic factors , the CYKIDS studyOBESITY REVIEWS, Issue 3 2008C. Lazarou Summary Obesity status differs by socio-demographic factors, but data for Cyprus are scarce. An in-depth understanding of this relationship may be useful in designing public health programmes. The objective of the present study is to estimate overweight and obesity (OW/OB) prevalence among children and adults in Cyprus and identify related socio-demographic variables. National cross-sectional study of 1140 children (mean age 11 ± 0.98 years) and their parents (mean age 42.5 ± 5.8 years, total n = 1954). Obesity was defined according to the World Health Organization classification for adults and according to IOTF (International Obesity Task Force) criteria for children. Overweight and obesity prevalence among girls was 18.3% and 2.9%, respectively, while in boys, 19.0% and 6.0%. Among parents, OW/OB prevalence was, respectively, women, 22.6% and 5.8%; men, 47.1% and 14.1%. Logistic regression analysis in both children and adults revealed that the most important socio-demographic predictors of obesity status are factors of built environment. Higher prevalence of OW/OB was observed in adults living in a house as opposed to an apartment, in older adults, in younger children, and in men, irrespective of age. There is a severe obesity problem in the Cypriot population; almost one in two adults and at least one in four preadolescent children are overweight or obese. Prevalence of OW/OB was related to socio-demographic factors, especially among adults and women.

CRF was predicted by maximal multistage 20 m shuttle-run test according to procedures described from FITNESSGRAM. Children's BMI was classified according to International Obesity Task Force and sleeping quality was assessed by questionnaire. The prevalence of overweight and obesity was 21.2% and 5.7%, respectively. Sleeping quality was significantly associated with CRF (Rho = 0.17; P < 0.05), but not with BMI. Girls who were classified as fit were more likely (OR: 2.25; P < 0.05) to report better sleep quality compared to their unfit peers. Poor sleep quality was associated with lower CRF although no associations have been shown with BMI. Am. J. Hum. Biol. 2010. © 2009 Wiley-Liss, Inc. [source] L-asparaginase as a marker of chemotherapy dose modification in children with acute lymphoblastic leukemiaCANCER, Issue 12 2005Jacques Baillargeon Ph.D. Abstract BACKGROUND The objective of the current study was to compare chemotherapy dose modifications in obese (a body mass index [BMI] > 95%) and nonobese (a BMI , 95%) pediatric patients with acute lymphoblastic leukemia (ALL). METHODS The study cohort was comprised of 199 pediatric patients diagnosed with ALL who were treated at 1 of 2 South Texas pediatric oncology centers between 1990,2000. The relative chemotherapy dose modification during the induction phase of chemotherapy was calculated as the ratio of 1) the actual administered dose of L-asparaginase and 2) the protocol-calculated dose of L-asparaginase. The extent to which the chemotherapy dose modification varied according to obesity status was assessed using stratified Student t tests and an ordinary least-squares regression analysis. RESULTS Obese ALL patients were found to exhibit a 7% decrease in the mean relative modification of L-asparaginase during induction chemotherapy compared with their nonobese counterparts. This finding was statistically significant (P = 0.009), even after adjustment for gender, age, ethnicity, and clinical institution. CONCLUSIONS To the authors' knowledge, the current study is the first published report of an obesity-associated chemotherapy dose modification in pediatric patients with ALL, the most common childhood malignancy. It will be important to examine whether these findings are consistent with those observed in future studies, and ultimately to assess the association between obesity-related dose modifications and long-term cancer outcomes.

[source] Body mass index, waist circumference and waist to hip ratio and change in sex steroid hormones: the Massachusetts Male Ageing StudyCLINICAL ENDOCRINOLOGY, Issue 1 2006Carol A. Derby Summary Objective, Cross-sectional data suggest that obesity, particularly central obesity, may be associated with decreased production of sex steroid hormones in men. However, longitudinal hormone data on men in relation to obesity status are limited. Previous studies have not consistently demonstrated whether sex steroids are associated specifically to body mass index or to measures of central obesity. Our objective was to examine the relation of obesity (body mass index > 30 kg/m2), and of central obesity (waist circumference > 100 cm or waist to hip ratio > 0·95) to longitudinal change in sex steroid hormones in men. Design, Prospective follow-up of a population-based sample of men in Boston. Patients, Nine hundred forty-two (942) men in the Massachusetts Male Ageing Study with complete anthropometry and hormone data at baseline (1987,1989, ages 40,70) and follow-up (1995,1997). Measurements, Free and total testosterone (FT and TT), dehydroepiandrosterone sulphate (DHEAS), and sex hormone-binding globulin (SHBG) were assessed using standardized methods. Health behaviours and medical history were obtained by structured interview. Repeated measures regression was used to describe trends in steroid hormones and SHBG in relation to obesity status, adjusting for age, smoking, alcohol, comorbidities, and physical activity. Results, Obesity was associated with decreased levels of total and free testosterone, and of SHBG at follow-up relative to baseline. For any given baseline concentration of TT, FT or SHBG, follow-up levels were lowest among men who remained obese or who became obese during follow-up. This was true for all three indices of obesity. Central adiposity was associated with lower DHEAS levels at follow-up, while elevated body mass index was not. Conclusions, Obesity may predict greater decline in testosterone and SHBG levels with age. Central adiposity may be a more important predictor of decline in DHEAS than is body mass index.
