Abstract Background This study investigates the association of clinical and demographic predictors with abdominal fat gain, measured using waist circumference (WC) and self-reported abdominal size. Methods We analyzed data from ACTG A5257, a clinical trial that randomized treatment-naïve HIV-infected participants to 1 of 3 antiretroviral regimens: raltegravir (RAL) or the protease inhibitors (PIs) atazanavir/ritonavir (ATV/r) or darunavir/ritonavir (DRV/r), each in combination with tenofovir disoproxil fumarate/emtricitabine. Associations of treatment and baseline/demographic characteristics with 96-week WC change were assessed using repeated-measures models. Ordinal logistic regression was used to examine the associations of predictors with week 96 self-reported abdominal changes. Results The study population (n = 1809) was 76.0% male and predominantly black non-Hispanic (41.9%) and white non-Hispanic (34.1%). Mean baseline WC was 90.6 cm, with an average 96-week increase of 3.4 cm. WC increases were higher in the RAL arm compared with DRV/r (P = .0130). Females experienced greater increases in WC on RAL vs ATV/r than males (P = .0065). Similarly, a larger difference in WC change was found for RAL vs DRV/r for black vs nonblack individuals (P = .0043). A separate multivariable model found that in addition to the treatment regimen, higher baseline viral load and lower CD4+ were also associated with WC increases. Conclusions With antiretroviral therapy initiation, higher WC increases in the RAL arm compared with PIs were more pronounced in female and black participants, and a more advanced baseline HIV disease state was a strong predictor of larger abdominal increases. Understanding factors predisposing individuals to abdominal fat gain could inform health management after therapy initiation.

Objective: This study aimed to Compare parametric indices of anthropometric and biomechanical characteristics of female basketball, volleyball, and handball players. Methods: This research is purposive comparative-descriptive study. A total of 100 female students (35 handball players, 37 volleyball players, and 28 basketball players) participated in this study. The normality of the data distribution was examined using the Kolmogorov-Smirnov test. The Mean±SD and percentage rank to describe the information, multiple correlation coefficient to reduce the overlapping data, and analysis of the main components of the data to determine the leading indicators of anthropometric and biomechanical characteristics of female handball, volleyball, and basketball players and ANOVA was used to compare the corresponding leading indices in different age groups. Results: Ten parameters for female handball and volleyball players and nine parameters for female basketball players were highlighted as the leading indicators. Head width, leg length, ankle width, scapular fat for basketball and handball players, biceps and weight for handball and volleyball players, abdominal fat, leg length for volleyball and basketball players, and height introduced as the leading common indicators among all groups of players. The results related to the variance extracted in each of the main components of anthropometric features after rotation showed that the main parameters related to anthropometric characteristics in female handball players are: height, weight, knee-to-ground height, head width, Head circumference, waist circumference, leg length, ankle width, scapular fat, and biceps fat; in female volleyball players are: height, weight, trunk width at the navel, sitting pelvis width, elbow circumference, knee circumference, foot arc circumference, leg length, biceps fat, triceps fat; in female basketball players are: height, elbow circumference, head width, trunk circumference at chest level, trunk circumference at navel level, leg length, ankle width, scapular fat, and abdominal fat; and in players of the three groups of athletes are: height, knee-to-ground height, elbow circumference, head circumference, waist circumference, trunk circumference at chest level, scapular fat and maximum forearm circumference. Conclusion: The height is the leading standard index between different female handball, volleyball, and basketball players. Most of the anthropometric characteristics are various, related to the type of sport. Also, the biomechanical characteristics vary according to the unique skills in each discipline. In some sports, the biomechanical factors vary due to the features of the common sport and the design of specific training programs. Every sport needs to evaluate and study the anthropometric and biomechanical aspects of individuals.

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。
