Media and popular literature link chocolate and sex-interest in women, but there is little research examining their association. This cross-sectional analysis sought to address this gap by assessing the relation of chocolate-consumption frequency to self-rated interest in sex. Seven-hundred twenty-three (723) Southern California men and women, age >20, completed surveys providing chocolate-consumption frequency (Choc0, x/week) and interest in sex (rated 0-10). Regression (robust standard errors) examined the relationship of chocolate-consumption frequency (Choc0, x/week) to sex-interest, adjusted for potential confounders. Tests for gender and age interactions guided gender- and age-stratified analyses. The mean sex-interest was 7.0±3.0 overall; 5.7±3.1 in women and 7.4±2.8 in men. The reported chocolate frequency was 2.0±2.5x/week overall; 2.5±2.8x/week in women and 1.8±2.4x/week in men. Those who ate chocolate more frequently reported lower interest in sex. Significance was sustained with an adjustment: per-time-per-week chocolate was eaten, β=-0.11(SE=0.050), p=0.02. The gender interaction was significant (p=0.03). The gender-stratified analysis showed the effect was driven by the much stronger relation in women: full model, per time-per-week chocolate consumed, β=-0.26(SE=0.08), p=0.002. Chocolate-consumption frequency was the strongest assessed predictor of sex-interest in women. A relationship was not observed in men, though a trend was present in younger men. Women who ate chocolate more frequently reported less interest in sex, a finding not explained by assessed potential confounders. Popular portrayals in which chocolate is represented as substituting for sex and "satisfying" the need for sex in women represent one possible explanation for these findings.
媒体和通俗文学将巧克力与女性的性趣联系起来，但很少有研究探讨它们之间的关联。这项横断面分析试图通过评估巧克力消费频率与自我评定的性趣之间的关系来填补这一空白。723名年龄大于20岁的南加州男性和女性完成了调查，提供了巧克力消费频率（巧克力0，每周x次）和性趣（评分为0至10）。回归分析（稳健标准误）检验了巧克力消费频率（巧克力0，每周x次）与性趣之间的关系，并对潜在混杂因素进行了调整。性别和年龄交互作用检验指导了按性别和年龄分层的分析。总体上，平均性趣为7.0±3.0；女性为5.7±3.1，男性为7.4±2.8。报告的巧克力食用频率总体上为2.0±2.5次/周；女性为2.5±2.8次/周，男性为1.8±2.4次/周。巧克力食用频率较高的人报告的性趣较低。调整后仍具有显著性：每周每次食用巧克力，β=-0.11（标准误=0.050），p=0.02。性别交互作用显著（p=0.03）。按性别分层的分析表明，这种影响在女性中更为强烈：完整模型中，每周每次食用巧克力，β=-0.26（标准误=0.08），p=0.002。巧克力消费频率是女性性趣最强的评估预测因素。在男性中未观察到这种关系，不过年轻男性中有这种趋势。巧克力食用频率较高且性趣较低的女性，这一发现无法用评估的潜在混杂因素来解释。巧克力在通俗描述中被描绘为替代性行为并“满足”女性性需求，这可能是这些发现的一种解释。
