运动减肥对重度肥胖女儿童青少年腰围、臀围以及腰臀比的影响

测定了参加＂2009年上海巅峰暑期减肥运动营＂23名重度肥胖女性儿童青少年运动减肥前后身体形态指标,经过4周运动减肥后,体脂百分比、体重指数（BMI）、脂肪体重、腰围、臀围都有不同程度的下降。体脂百分比下降幅度明显大于BMI,腰围/身高比的下降幅度明显大于臀围/身高比。与BMI比较,体脂百分比是评价肥胖程度和运动减肥效果的理想指标。     

Dynamic sitting: Measurement and associations with metabolic health

Dynamic sitting, such as fidgeting and desk work, might be associated with health, but remains difficult to identify out of accelerometry data. We examined, in a laboratory study, whether dynamic sitting can be identified out of triaxial activity counts. Among 18 participants (56% men, 27.3 ± 6.5 years), up to 236 counts per minute were recorded in the anteroposterior and mediolateral axes during dynamic sitting using a hip-worn accelerometer. Subsequently, we examined in 621 participants (38% men, 80.0 ± 4.7 years) from the AGES-Reykjavik Study whether dynamic sitting was associated with cardio-metabolic health. Compared to participants who recorded the fewest dynamic sitting minutes (Q₁), those with more dynamic sitting minutes had a lower BMI (Q₂ = ?1.39 (95%CI = ?2.33;–0.46); Q₃ = ?1.87 (?2.82;–0.92); Q₄ = ?3.38 (?4.32;–2.45)), a smaller waist circumference (Q₂ = ?2.95 (?5.44;–0.46); Q₃ = ?3.47 (?6.01;–0.93); Q₄ = ?8.21 (?10.72;–5.71)), and a lower odds for the metabolic syndrome (Q₂ = 0.74 [0.45;1.20] Q₃ = 0.58 [0.36;0.95]; Q₄ = 0.36 [0.22;0.59]). Our findings suggest that dynamic sitting might be identified using accelerometry and that this behaviour was associated with health. This might be important given the large amounts of time people spend sitting. Future studies with a focus on validation, causation and physiological pathways are needed to further examine the possible relevance of dynamic sitting.     

公安院校大学男生不同BMI指数与身体机能、形态指标的差异性比较研究

采用文献资料法、比较研究法以及数理统计等方法,依据世界卫生组织关于BMI的分型标准对352名浙江警察学院大学男生的部分身体机能及身体形态指标进行统计分析,结果表明:①我校大学男生BMI指数在18.5≤BMI≤25的比例占研究样本的90.6%,总体处于较佳水平;②身高和胸围对肺活量都有显著影响,身体质量以及身高对肺活量的影响呈正相关;③体重超重学生在体脂肪、体脂百分比及腰臀脂肪比指标上与体重正常和处于过轻体重(低体重)的学生均存在非常显著差异。     

不同体质指数大学生的体质状况比较研究

通过文献资料法、数理统计法、比较分析法对不同BMI组别大学生的体质状况进行研究.结果发现,不同身体质量指数(BMI)大学生的体质存在显著差异.肥胖者的所有身体素质均显示出最差态势,说明肥胖是影响身体素质的重要因素;BMI正常男生的有氧耐力、弹跳、柔韧均好于其它BMl组别者;BMI偏低女生的身体素质则相对好于其它组别(柔韧性除外);BMI偏低学生的柔韧性较差.     

幼儿肥胖与父母肥胖的关系研究

目的：探讨父母肥胖对幼儿肥胖的影响。方法：随机抽取山东省17地市3～6岁幼儿进行调查分析,对其父母进行问卷调查以获得父母的身高、体重。应用WHO推荐的身高标准体重法：≥120％作为幼儿肥胖判断标准,以BMI超过25或28kg／m^2为判断标准判断父母超重或肥胖。结果：父亲正常、超重及肥胖时幼儿肥胖率分别为5．49％,9．20％和14．43％;母亲正常、超重及肥胖时幼儿肥胖率分别为6．86％,12．12％和13．98％,各组肥胖率之间差异显著（P〈0．05）。父母均正常的幼儿肥胖发病率为6．30％,而父母均超重或肥胖时幼儿的肥胖发病率上升到20．45％。幼儿BMI与父母的BMI明显相关,相关系数分别为0．162和0．133。结论：父母肥胖是幼儿肥胖的重要危险因素,父母肥胖的幼儿应成为预防肥胖的重点人群。     

运动干预对改善高职院校肥胖学生BMI指数的实验与效果分析

运用文献资料、调查、数理统计、逻辑分析等方法,根据学生个体的不同,通过运动处方、自觉训练和监督指导的运动干预方式对肥胖学生进行长达6个月的实验研究,探讨运动干预对改善BMI指数影响程度.结果表明:引起高职院校学生肥胖的主要因素之一是缺乏运动;运用运动干预的方式对改善肥胖学生的BMI指数有明显的效果,为降低高职院校学生肥胖率找到好的方式和方法,也为职院肥胖学生科学减脂提供好的方法和借鉴.     

Peer teasing experiences of fathers and their children: Intergenerational associations and transmission mechanisms

Being the victim or perpetrator of peer teasing threatens children’s immediate and long-term well-being. Given that many individual and contextual risk factors for peer victimization are transmitted within families, we tested whether fathers’ childhood victimization experiences were directly or indirectly (via poor parenting and poor child adjustment) associated with their children’s increased risk for similar experiences. Generation two (G2) fathers (n = 130) who had been assessed since age 9 years participated in an intergenerational study with their 268 G3 children and the 163 G2 mothers of these children. Peer teasing ratings were collected annually from G1 mothers, fathers, and teachers across G2 ages 9–16 years, and from the same three informant types across the same ages for G3 children. Also assessed was G2 fathers’ poor parenting of G3 at ages 3–7 years and G3 poor adjustment (externalizing and internalizing behaviors, deviant peer association, low social competence) and body mass index (BMI) at ages 7–16 years. Models supported intergenerational stability in being teased that was partially mediated through G2 fathers’ poor parenting and G3 poor adjustment. A direct intergenerational path in being teased remained significant, and G3 BMI uniquely predicted being teased. Childhood peer victimization is perpetuated across generations. Prevention aimed at poor parenting, child poor adjustment, and peer victimization itself may disrupt intergenerational stability in these adverse experiences.

BMI指数与大学生体质健康的相关关系分析——以东北师范大学为例

通过对东北师范大学4000名学生(男生2000人、女生2000人)的体质指数与大学生体质健康测试标准进行相关性检验分析,结果表明:东北师范大学学生体质指数(BMI指数)相对集中,总体分布正常,且男生的肥胖率高于女生肥胖率。通过对4000名大学生的体质测试得出,大学生BMI指数对身体素质和身体机能都有影响,尤其对肥胖和超重的学生影响较大。分析结果表明,在肥胖和超重的学生中,耐力、爆发力、速度和移动都随着BMI值的增加而呈下降趋势,对学生身心发展产生不良影响。
