Background:The influence of physical activity (PA) changes on risk of abdominal fat gain in midlife women has not been studied using objective measures and controlling for potentially confounding variables.Methods:Changes in PA were assessed within a prospective cohort of 233 middle-age (40 ± 3 years), nonobese, nonsmoking, primarily Caucasian women by using accelerometers, worn continuously for 7 consecutive days at baseline and again at a 20 month follow-up. Weighed food intake diaries were completed on concurrent days. Bod Pod assessed total body fat. Abdominal fat was measured by abdominal circumference at the umbilicus.Results:Women who decreased PA gained abdominal fat across 20 months, while women who increased PA (F = 4.82, P = .009) did not. Change in PA remained an independent predictor of abdominal fat change after adjusting for potential confounders, including changes in total body fat and total energy intake. Compared with women who maintained or decreased PA, women who increased PA had approximately half the risk (RR = 0.52, 95% CI: 0.27, 0.98) of gaining abdominal fat.Conclusions:Increasing daily physical activity may attenuate risk of abdominal fat gain in middle-age women independent of changes in total body fat or energy intake.

AbstractBackground:The aim of the study was to assess possible relationships between adipocyte fatty acid-binding protein (FABP4) and total body fat (TBF), abdominal fat, body fat distribution, aerobic fitness, blood pressure, cardiac dimensions and the increase in body fat over 2 years in a community sample of children.Methods:A cross-sectional study was used in a community sample of 170 (92 boys and 78 girls) children aged 8–11 years. TBF and abdominal fat (AFM) were measured by dual-energy X-ray absorptiometry (DXA). TBF was also expressed as percentage of total body mass (BF%), and body fat distribution was calculated as AFM/TBF. Maximal oxygen uptake (VOResults:Partial correlations, with adjustment for sex, between FABP4 vs. ln TBF, ln BF%, ln AFM, AFM/TBF and VOConclusions:Findings from this community-based cohort of young children show that increased body fat and abdominal fat, more abdominal body fat distribution, low fitness, more LVM and increased LA, increased SBP and PP were all associated with increased levels of FABP4. Increase in TBF and abdominal fat over 2 years were also associated with increased levels of FABP4.

LANGUAGE NOTE | Document text in English; abstract also in Chinese.The importance of reducing health risk associated with high abdominal fat is frequently emphasized. Consequently, in Singapore, we have witnessed good sales on motorized mechanical oscillators touted to induce slimming based on the principles of acupressure. However, to date, no study has been done to evaluate the efficacy of such equipment. This pilot study aims to examine the efficacy of motorized mechanical oscillators in reducing waist circumference, weight and abdominal fat percentage over 4 weeks as well as augment the data on acupressure for weight reduction. Two male subjects, one mildly overweight and the other severely overweight, were recruited. They were required to keep to their existing lifestyles and dietary habits and were instructed to wear the oscillator belt for 30 minutes each time, twice a day, as per instructions given in the manual. The machine was operated using the automatic mode. The results show a slight decrease in total body fat % ascertained by DEXA scans. There was also a reduction in waist circumference and an increase in lean mass in the trunk area in both subjects. Specifically, one participant (mildly overweight) lost 1.2% of total body fat, and 0.7cm on the waist girth but gained 1 kg of lean trunk mass. The other participant (severely overweight), although having lost only 0.2% of total body fat and 1.3cm on the waist girth, lost 1.7 kg in total body weight. He also gained in trunk lean mass that resulted in trunk fat reduction of 0.4%. There appears to be some success in such treatment modality particularly with regard to reducing abdominal fat. Certainly, more work needs to be done and future studies are being considered that will involve bigger sample sizes.調查顯示腹部脂肪的累積能引起健康危害,因此減少腹部脂肪的重要性需要廣泛重視的。在新加坡,瘦身產品如動力化的機械擺動瘦身帶都獲得非常好的銷售額。此瘦身帶是以穴位理療原理為依據而設計開發的。可是至今,這類產品的瘦身效果還沒得到科學證明。這項中間試驗的目的是研究在超過4個星期的時間裏,這類瘦身帶對減少腰圍,體重和腹部脂肪的百分數效果;同時也希望增添用穴位理療原理在減肥方面的資料。在二位男性患者當中,一位屬於輕微超重,而另一位屬於嚴重超重。在這項中間試驗調查中,二位患者接受了為期四周的治療療程。療程包括每日使用本瘦身帶二次,一次療程三十分鐘。除此以外,患者需要保持原本的生活方式和飲食習慣。並遵循指導手冊方法操作。此瘦身帶的操作是採用自動化的方法。由DEXA結果顯示二位元患者的脂肪都有顯微的下降,腰圍也有所減小,並且腹部的肌肉有明顯的增加。其中一位患者(輕微肥胖者)的脂肪減少了1.2%,腰圍減少了0.7公分,而肌肉增加了1公斤。第二位患者的身體脂肪減少了0.2%,腰圍減少了 1.3公分,體重也減輕了1.7公斤。同時肌肉也增加了,這使到他的腹部的脂肪減少了0.4%。由此可見,這類瘦身方法對減少腹部脂肪似乎有效。所以,這方面的調查和研究需要更多的工作。接下來希望進行更廣泛,更大規模的研究。

We assessed the associations between changes in total and abdominal fat and changes in biomarkers for breast cancer risk using data of the SHAPE-2 trial. In the SHAPE-2 trial, 243 postmenopausal overweight women were included. The intervention in this trial consisted of 5-6 kg weight loss either by diet only or exercise plus diet. After 16 weeks, we measured serum sex hormones, inflammatory markers, total body fat (measured by DEXA scan) and intra and subcutaneous abdominal fat (measured by MRI). Associations between changes in different body fat depots and biomarkers were analysed by linear regression using the study cohort irrespective of randomisation to make maximal use of the distribution of changes in fat measures. We found that a loss in total body fat was associated with favourable changes in free oestradiol, free testosterone, leptin and sex hormone binding globulin (SHBG). The loss of intra-abdominal fat was associated with a decrease in free testosterone, hsCRP and leptin, and an increase in SHBG. In the multivariable analysis, the best fitted models for the biomarkers free oestradiol, SHBG leptin and adiponectin included only total body fat. For free testosterone, this was subcutaneous abdominal fat, and for hsCRP and IL-6, only intra-abdominal fat change was important. For IL-6 and adiponectin, however, associations were weak and not significant. We conclude that, in our population of healthy overweight postmenopausal women, loss of fat at different body locations was associated with changes in different types of biomarkers, known to be related to risk of breast cancer.

AbstractThe appropriate percentage of body fat is essential for women’s health and biological condition. Both accumulation of fat and distribution pattern of adipose tissue are connected with health risk, which justifies the investigation and permanent monitoring of their diversity in different sub-populations. The aim of the study was to evaluate the percentage of body fat and its distribution in female students representing different physical activity levels.Fat proportion was estimated with use of classic anthropometric method and bioelectrical impedance analysis (BIA). The distribution of subcutaneous fat was calculated including waist and hip circumferences, and extremities and trunk skinfolds. The participants’ level of physical activity was determined according to the IPAQ questionnaire.Analysis showed that female students with medium level of physical activity had 26.5 ± 5.1% of total body fat estimated by BIA, whereas in the most active females almost 3% lower total body fat values were common. The bioelectrical impedance analysis indicated about 8% higher body fat content than classic anthropometry. Examined skinfolds revealed a tendency to decrease with increasing physical activity. The distribution pattern of subcutaneous fat varied according to level of activity.The study showed that estimation of fat content in young women differed depending on the applied method and the level of physical activity. We emphasize the need to select adequate reference data for measurement methods and consider the level of physical activity during fat percentage assessment. Another conclusion is that the high level of physical activity is connected with masculinization of subcutaneous fat pattern, both in extremities/trunk fat proportion and waist/hip proportion.
