Food intake and motivation for food varies according to the phase of the menstrual cycle. These changes seem to be more marked in women with premenstrual syndrome (PMS) and may be modified by the use of oral contraceptives (OC). This study examined the effect of menstrual cycle, PMS and OC use on the intake and hedonic rating of sweet and savory snack foods.
Fifty-five women were recruited and assigned to either a PMS group or a control group. In addition, based on OC use, the women were assigned to an OC-user or non-user group. During the luteal and follicular phases, the participants were asked to consume and rate sweet and savory snacks.
The luteal phase induced greater caloric intake from sweet foods. PMS sufferers did not consume significantly more calories in either phase. There was a significant interaction between phase, flavor, PMS status and OC use. OC users consumed more calories from sweet foods in the follicular phase.
Food intake is increased in the luteal phase. This effect was modulated by both PMS and OC use. OC use seems to eliminate cyclic fluctuations in caloric intake.
食物摄入量及对食物的喜好会根据月经周期的阶段而变化。这些变化在经前综合征（PMS）女性中似乎更为明显，并且可能会因口服避孕药（OC）的使用而改变。本研究考察了月经周期、经前综合征和口服避孕药的使用对甜味和咸味休闲食品摄入量及享乐评分的影响。
招募了55名女性，并将她们分为经前综合征组或对照组。此外，根据口服避孕药的使用情况，将这些女性分为口服避孕药使用者组或非使用者组。在黄体期和卵泡期，要求参与者食用并评价甜味和咸味零食。
黄体期会使来自甜食的热量摄入增加。经前综合征患者在两个阶段的热量摄入均未显著增加。在阶段、口味、经前综合征状态和口服避孕药使用之间存在显著的交互作用。口服避孕药使用者在卵泡期从甜食中摄入的热量更多。
黄体期的食物摄入量会增加。这种影响受到经前综合征和口服避孕药使用的调节。口服避孕药的使用似乎消除了热量摄入的周期性波动。
