One way of promoting a reduction in dietary fat intake is by changing the diet of family members. This study investigated the long-term effects of a low-fat dietary intervention on husbands of women who participated in the Women's Health Trial (WHT).
An average of 12 months after the end of the WHT, a randomly selected sample of participants' husbands was sent dietary and health questionnaires as part of a follow-up study of the maintenance of the low-fat diet among WHT participants.
We found an absolute difference in fat intake between groups of 4 percentage points (32.9% energy from fat among intervention husbands [n = 188] vs 36.9% among control husbands [n = 180]). The wife's attitude and fat intake were among the most important predictors of her husband's fat intake, indicating that the effect of the WHT intervention on the husbands of participants was more likely due to their acceptance of lower-fat foods being served at home than to overt actions by the men.
Our results suggest that a dietary intervention aimed at women can have an effect on their husbands and may be a cost-effective approach to healthy dietary change for both women and men.
促进减少膳食脂肪摄入量的一种方法是改变家庭成员的饮食。本研究调查了低脂饮食干预对参与女性健康试验（WHT）的女性的丈夫的长期影响。
在WHT结束后平均12个月，作为对WHT参与者维持低脂饮食的后续研究的一部分，随机抽取参与者的丈夫样本，向其发送饮食和健康问卷。
我们发现两组之间的脂肪摄入量绝对差异为4个百分点（干预组丈夫中来自脂肪的能量为32.9%[n = 188]，对照组丈夫中为36.9%[n = 180]）。妻子的态度和脂肪摄入量是其丈夫脂肪摄入量的最重要预测因素之一，这表明WHT干预对参与者丈夫的影响更可能是由于他们接受了家中提供的低脂食物，而不是男性的公开行动。
我们的结果表明，针对女性的饮食干预可能会对其丈夫产生影响，并且可能是一种对女性和男性进行健康饮食改变的具有成本效益的方法。
