青年男子的飲食習慣和精液質量

 

來自美國哈佛大學羅切斯特大學的研究

 

研究的問題:不同的飲食模式與年輕男性精液質量有關嗎?

答案:謹慎的飲食習慣具有較好的精子快速活動力,但和精子濃度與型態無關。“西方”的飲食習慣模式則無關於精液分析的係數改變。


什麼是已知:在過去的幾十年裡,一直在精子和飲食質量的同時下降的證據。但飲食成分是否影響精液的質量,還有很多的未知。


研究設計,大小,持續時間:羅切斯特大學年輕男性的研究(188人)之間進行的橫截面研究。2009年和2010年在美國羅切斯特大學。參與者,設置,方法包括:男性,年齡18-22歲,這一分析。通過飲食進行了評估食物頻率確定了因子分析問卷和飲食模式。線性回歸的方法來分析的飲食方式之間的關係和傳統的精液質量參數(精子密度,活力和形態進步的)調整禁慾時間,多種維生素使用,種族,吸煙,BMI,研究期間,中度至劇烈的運動和總熱量攝入。
確定了因素分析的結果:兩種飲食模式。 “西方”模式的特點是攝入量高的紅色和加工肉類,
精緻的穀物,比薩,零食,高能量飲料和糖果。 “謹慎” 飲食模式的特點是魚的攝入量高的,雞,水果,蔬菜,豆類和粗糧。謹慎的飲食呈現較好的精子快速活動力正相關%逐步游動的精子在多變量模型(P-trend=0.04的趨勢)。在最高四分位數的謹慎飲食男性高11.3%(95CI1.321.3)%逐步活動精子與男性相比,在最低四分位數。謹慎的模式是精子的濃度和形態無關。西方的模式是不相關的任何精液參數。

study question: Are different dietary patterns associated with semen parameters in young men?

study answer: The consumption of a Prudent dietary pattern was significantly associated with higher progressive sperm motility and

unrelated to sperm concentration and morphology. The consumption of a Western dietary pattern was unrelated to conventional semen

quality parameters.

what is known already: Over the past decades there has been evidence of a concomitant decline in sperm and diet quality. Yet

whether diet composition influences semen quality remains largely unexplored.

study design, size, duration: The Rochester Young Mens Study ( 188) was a cross-sectional study conducted between

2009 and 2010 at the University of Rochester .

participants, setting, methods: Men aged 1822 years were included in this analysis. Diet was assessed via food frequency

questionnaire and dietary patterns were identified by factor analysis. Linear regression was used to analyze the relation between diet patterns

and conventional semen quality parameters (sperm concentration, progressive motility and morphology) adjusting for abstinence time, multivitamin

use, race, smoking status, BMI, recruitment period, moderate-to-intense exercise and total calorie intake.

results: Two dietary patterns were identified by factor analysis. The Western pattern was characterized by high intake of red and processed

meat, refined grains, pizza, snacks, high-energy drinks and sweets. The Prudent pattern was characterized by high intake of fish,

chicken, fruit, vegetables, legumes and whole grains. The Prudent pattern was positively associated with percent progressively motile

sperm in multivariate models (P-trend= 0.04). Men in the highest quartile of the Prudent diet had 11.3% (95% CI 1.3, 21.3) higher % progressively

motile sperm compared with men in the lowest quartile. The Prudent pattern was unrelated to sperm concentration and morphology.

The Western pattern was not associated with any semen parameter.
