Background

Studies on associations between maternal personality and alcohol use have examined only one time point during pregnancy in Western countries. We aimed to examine the association between maternal personality and alcohol use in early and middle pregnancy in Japan.

Methods

We analyzed data from 17,144 pregnant women in Japan who participated in the Tohoku Medical Megabank Project Birth and Three-Generation Cohort Study from 2013 to 2017. Personality was assessed using the short-form Eysenck Personality Questionnaire-Revised. Women were dichotomized as current drinkers or non-drinkers in both early and middle pregnancy. Odds ratios (ORs) and 95% confidence intervals (CIs) for alcohol use in early and middle pregnancy and continued alcohol use between early and middle pregnancy were calculated for 1 standard deviation increase in each personality scale, adjusted for age, as well as education, work status, fertility treatment, and parity.

Results

Higher extraversion scores were associated with alcohol use in early (OR, 1.16; 95% CI, 1.12–1.20) and middle pregnancy (OR, 1.17; 95% CI, 1.10–1.25). Higher psychoticism scores were associated with continued alcohol use into middle pregnancy (OR, 1.07; 95% CI, 1.01–1.14) and alcohol use in middle pregnancy (OR, 1.07; 95% CI, 1.02–1.13). Neuroticism was not associated with alcohol use in early or middle pregnancy. Lower lie was associated with alcohol use in early (OR, 0.95; 95% CI, 0.91–0.98), but not in middle pregnancy.

Conclusions

Different personality scales are associated with alcohol use at different points during pregnancy.

日本孕期母亲性格和饮酒：东北医疗大银行项目出生和三代队列研究

背景

在西方国家，关于母亲性格与饮酒之间关联的研究只检查了怀孕期间的一个时间点。我们的目的是检查日本孕早期和中期孕产妇性格与饮酒之间的关联。

方法

我们分析了 2013 年至 2017 年日本参加 Tohoku Medical Megabank 项目出生和三代队列研究的 17,144 名孕妇的数据。使用 Eysenck Personality Questionnaire-Revised 的简短形式评估个性。在怀孕早期和中期，女性被分为当前饮酒者或不饮酒者。计算每个人格量表增加 1 个标准差并根据年龄和教育程度进行调整后，计算出妊娠早期和中期饮酒以及妊娠早期和中期继续饮酒的比值比 (OR) 和 95% 置信区间 (CI) 、工作状态、生育治疗和均价。

结果

较高的外向性评分与妊娠早期 (OR, 1.16; 95% CI, 1.12-1.20) 和中期妊娠 (OR, 1.17; 95% CI, 1.10-1.25) 的饮酒有关。较高的精神病评分与妊娠中期持续饮酒 (OR, 1.07; 95% CI, 1.01–1.14) 和妊娠中期饮酒 (OR, 1.07; 95% CI, 1.02–1.13) 相关。神经质与妊娠早期或中期饮酒无关。低位与早期饮酒有关（OR，0.95；95% CI，0.91–0.98），但与妊娠中期无关。

结论

不同的人格量表与怀孕期间不同时期的酒精使用有关。
