摘要

据信,身体成分同时变化的现象可能对整体健康产生更大的负面影响。因此,我们的目的是调查伴随的身体成分紊乱的患病率,并评估其与饮食摄入、久坐行为、肌肉力量和运动表现的关系。这是一项横断面研究,从圣保罗市健康调查中招募了218名年龄在63(59-69)岁、男女(52%为女性)的社区居住成年人。评估包括通过DXA测量的阑尾瘦质量(LM)、脂肪质量和骨密度(BMD)、握力、静坐时间和饮食摄入量。受试者被分为8组:(1)正常,(2)骨质减少(OP),(3)低LM,(4)肥胖,(5)OP +低LM,(6)肥胖+ OP,(7)肥胖+低LM,(8)肥胖+ OP +低LM。统计分析包括方差分析、卡方检验和线性回归模型。52人(23%)表现出肥胖与另一种身体成分变化相关,14人(6%)同时存在3种情况(肥胖+ OP +低LM)。肥胖组蛋白质摄入量均较低();而肥胖组或肥胖+低LM组保持坐姿的时间更长(),肥胖+ OP +低LM组握力最低。肥胖合并低LM和低OP是与握力降低相关的加重因素。在人口和营养转变的背景下,研究结果表明需要进行纵向调查。

Obesity Associated with Low Lean Mass and Low Bone Density Has Higher Impact on General Health in Middle-Aged and Older Adults
It is believed that the phenomenon of simultaneous changes in body composition could have a higher negative impact on general health. Thus, we aimed to investigate the prevalence of concomitant body composition disturbances and evaluate the association with dietary intake, sedentary behaviour, muscle strength, and performance. This is a cross-sectional study with 218 community-dwelling adults, aged 63 (59–69) years, both sexes (52% female) recruited from the Health Survey of the City of Sao Paulo. Assessments include appendicular lean mass (LM), fat mass and bone mineral density (BMD) by DXA, grip strength, time spent sitting, and dietary intake. Subjects were clustered into 8 groups: (1) normal, (2) osteopenia (OP), (3) low LM, (4) obesity, (5) OP + low LM, (6) obesity + OP, (7) obesity + low LM, and (8) obesity + OP + low LM. Statistical analyses include ANCOVA, the chi-square test, and linear regression models. 52 (23%) individuals presented obesity associated with another body composition change, with 14 (6%) having the combination of the 3 conditions (obesity + OP + low LM). All groups with obesity showed lower protein intake ( ); however, those with obesity or obesity + low LM spent more time in a sitting position ( ), and the group with obesity + OP + low LM had the lowest grip strength. The combination of obesity with low LM and OP presented the aggravating factor of being associated with lower grip strength. In a context of demographic and nutrition transition, the findings represent a demand for longitudinal investigations.
