上海市235名素食者素食类型和时间对其体成分的影响
目的了解不同素食类型和素食时间对素食者体成分状态的影响。方法 2012年4月—2013年7月在上海市市中心10家素餐馆中招募愿意接受调查的上海市区成年健康素食者235名,按照素食类型分为全素组(n=99)和奶蛋素组(n=136),按照素食时间分为素食〈5年组(n=157)和素食≥5年组(n=78),分别实施问卷调查,测量身高和体质量,采用人体成分分析仪进行体成分测量。结果多因素分析发现:校正年龄、性别和素食时间后,全素组与奶蛋素组人体蛋白质、骨骼肌、矿物质及脂肪的百分含量等体成分指标的差异无统计学意义(P〉0.05);校正年龄、性别、素食时间和膳食能量摄入量后,两组超重/肥胖的发病危险性无显著...

Summary: | 目的了解不同素食类型和素食时间对素食者体成分状态的影响。方法 2012年4月—2013年7月在上海市市中心10家素餐馆中招募愿意接受调查的上海市区成年健康素食者235名,按照素食类型分为全素组(n=99)和奶蛋素组(n=136),按照素食时间分为素食〈5年组(n=157)和素食≥5年组(n=78),分别实施问卷调查,测量身高和体质量,采用人体成分分析仪进行体成分测量。结果多因素分析发现:校正年龄、性别和素食时间后,全素组与奶蛋素组人体蛋白质、骨骼肌、矿物质及脂肪的百分含量等体成分指标的差异无统计学意义(P〉0.05);校正年龄、性别、素食时间和膳食能量摄入量后,两组超重/肥胖的发病危险性无显著差异(P〉0.05),但奶蛋素组发生中心性肥胖的危险性显著低于全素组(OR=0.164,95%CI 0.048~0.554,P=0.004);素食〈5年组与素食≥5年组上述指标的差异无统计学意义(P〉0.05)。结论不同素食类型和素食时间长短对各项体成分指标无明显影响;奶蛋素可能比全素更有助于降低发生中心性肥胖的危险性,但尚需进一步研究加以证实。 |
