“…In that study, Ebbeling et al (44) found that those assigned to receive non-caloric beverage provisions for 1 year had smaller gains in BMI compared with those assigned to the control group. Interestingly, body fat did not relate to the experimental condition, but it was obtained by bioelectrical impedance (as opposed to DXA as in our study), which has been shown to inaccurately measure body fat in overweight individuals (45) .…”

Objective: To determine the prospective relationship between changes in sugarsweetened beverage (SSB) intake and central adiposity in older children. Design: Dietary intakes of children were obtained by 3 d food records at ages 10 and 13 years. Waist circumference (WC) and weight and height to determine BMI were measured at 10 and 13 years and total body fat mass (TBFM) at 13 years by dual-energy X-ray absorptiometry. Analyses were conducted using multivariable linear regression. Reporting errors were measured and participants were categorized as under-, plausible and over-reporters of dietary intakes. Setting: Community-based British cohort of children participating in the Avon Longitudinal Study of Parents and Children. Results: Among 2455 older children, increased SSB consumption from ages 10 to 13 years was associated with higher WC (standardized β = 0·020, P = 0·19), BMI (β = 0·028, P = 0·03) and TBFM (β = 0·017, P = 0·20) at 13 years. Effects were strengthened among plausible dietary reporters (n 1059): WC (β = 0·097, P < 0·001), BMI (β = 0·074, P < 0·001) and TBFM (β = 0·065, P = 0·003). The association between change in SSB and WC was weakened, but remained statistically significant after accounting for BMI (β = 0·042, P = 0·02) and TBFM (β = 0·048, P = 0·01). Conclusions: Higher consumption of SSB from ages 10 to 13 years was associated with a larger WC at age 13 years independent of differences in total adiposity. Accounting for dietary reporting errors strengthened associations. Our findings further support recommendations to limit intakes of SSB to reduce excess weight gain in children and suggest that SSB have an additional deleterious effect on central adiposity. Keywords Sugar-sweetened beverages Waist circumference Children ObesityObesity is a primary threat to public health. Childhood obesity strongly tracks with age (1) , raising the risk of mortality, CVD, certain cancers and osteoarthritis, as well as other conditions in adulthood (2)(3)(4)(5) . In adults a key driver of the metabolic consequences of excess fat is that located abdominally, or central adiposity, which predicts mortality and CVD independent of BMI (5)(6)(7) . Currently 32 % and 17 % of children and adolescents in the USA are overweight and obese, respectively (8) . Moreover, waist circumference (WC) of children has increased over time and some evidence suggests that the rate of increase in WC has outpaced that of BMI (9)(10)(11)(12)(13) . Therefore, it is paramount to identify modifiable risk factors of excess total and abdominal weight gain in children to help prevent or reverse obesity and its related co-morbidities both in childhood and later life.To date it remains unclear as to whether intake of sugar-sweetened beverages (SSB) has specific effects

“…In this study, body composition was assessed with BIA, a method that may be less precise in overweight adults. 24 In addition, the study length was possibly too short for an effect to be observed. A commonality among the three remaining studies in overweight adults that did not find an effect of CLA on body fat was the inclusion of a weight loss component: Whigham et al 13 included a 12-week very low-calorie diet (VLCD); Kamphius et al 12 utilized a 3-week VLCD; and Atkinson 7 included a diet and exercise regimen during 6 months of treatment.…”

The role of conjugated linoleic acid in reducing body fat and preventing holiday weight gain

et al. 2006

Objective: The incidence of obesity and overweight in the US has increased considerably during the past two decades and currently affects 65% of the adult population. Research has indicated that small, yet irreversible, gains during the holiday season contribute to increases in weight during adulthood. Conjugated linoleic acid (CLA), a naturally occurring dietary fatty acid, has been found to reduce weight gain and dramatically decrease fat mass in animals. Although research in humans has shown inconsistent results, most studies have been of insufficient duration or have utilized body composition methods that are less accurate than the currently accepted criterion. Design: Randomized, double-blind, placebo-controlled study of 3.2 g/day CLA for 6 months. Subjects: Forty healthy, overweight subjects (age: 18-44 years; body mass index: 25-30 kg/m 2 ). Measurements: Body composition by the four-compartment model, resting metabolic rate (RMR) by indirect calorimetry, selfreported physical activity and dietary intake, and blood chemistries were determined at baseline and after 6 months. Body weight was measured monthly during the pre-holiday season (August-October), holiday season (November-December) and post-holiday season (January-March). Adverse events were assessed monthly. Results: Compared to CLA, the placebo group showed a greater rate of weight gain during the holiday season (P ¼ 0.01). Within the placebo group, holiday weight change was significantly greater compared to the pre-holiday period (August-October) (P ¼ 0.03). Six-month change in body composition was improved with CLA compared to placebo (P ¼ 0.02), and body fat was significantly reduced within the CLA group (À1.072.2 kg, P ¼ 0.05). CLA had no effect on RMR, physical activity or dietary intake. The rate of reported negative emotions decreased significantly with CLA, although there was no difference in any other category of adverse event. In comparison to the placebo, CLA did not affect insulin resistance, blood lipids and markers of liver function or markers of inflammation, with the exception of a significant decrease in a biomarker of endothelial dysfunction. Conclusion: CLA supplementation among overweight adults significantly reduced body fat over 6 months and prevented weight gain during the holiday season. Although no adverse effects were seen, additional studies should evaluate the effect of prolonged use of CLA.

“…BMI (kg m À2 ) was calculated as body weight/(estimated height) 2 . Body composition (fat mass) was measured, for patients able to stand up, by using the Tanita DC-320 (Tanita Corp., 232 Tokyo, Japan) BIA device based on four separate foot-pad electrodes mounted on the system's base, 21 with subjects in indoor clothing and no shoes.…”

Aortic stiffness, inflammation, denutrition and prognosis in the oldest people

et al. 2011

View full text Add to dashboard Cite

Observational studies have shown that some of the classic CV risk factors, namely hypertension or hypercholesterolemia, become nebulous, or even act in the reverse direction, in the oldest people. We investigated whether in the elderly, increased aortic stiffness was associated with higher mortality risk, before and after adjustments on common geriatric confounders. In a cohort of 331 (86 men) subjects aged 470 years (mean age ( ± s.d.): 85 ± 7 years), aortic stiffness was assessed by carotid-femoral pulse wave velocity (PWV). Classical CV risk factors were determined simultaneously, in association with inflammation and denutrition parameters. One hundred and ten subjects died during a 2-year follow-up period. In crude analysis, a positive non-significant trend was observed between PWV and mortality risk. Multivariate Cox regression analysis showed that five parameters entered the prediction model: two were positively related to mortality risk, PWV (P ¼ 0.008) and orosomucoide (P ¼ 0.045), and three were related negatively, total cholesterol (P ¼ 0.006), albumin (P ¼ 0.026) and body weight (P ¼ 0.035). Interaction analysis revealed that the effect of PWV on mortality was increased in the presence of renal dysfunction and increased inflammation. In conclusion, although marginally significant in crude analysis, PWV is a powerful determinant of prognosis in the oldest people taking into account inflammation and denutrition.

Comparison of multifrequency bioelectrical impedance analysis with dual-energy X-ray absorptiometry for assessment of percentage body fat in a large, healthy population

Abstract: BIA is a good alternative for estimating %BF when subjects are within a normal body fat range. BIA tends to overestimate %BF in lean subjects and underestimate %BF in obese subjects.
