Maternal risk factors for pregnancy outcomes are known to vary by employment status. We evaluated whether pre-pregnancy diet quality varies by occupation in a population-based sample.
We analysed interview data from 7341 mothers in a national case-control study of pregnancy outcomes. Self-reported job(s) held during the 3 months before pregnancy were classified using Standard Occupational Classification (SOC) codes. Usual diet in the year before conception was assessed with a semi-quantitative FFQ and evaluated using the Diet Quality Index for Pregnancy (DQI-P). Using logistic regression, we calculated adjusted OR and 95 % CI to estimate associations between low diet quality (defined as the lowest quartile of DQI-P scores) and occupation types.

Employed mothers of infants born between 1997 and 2011.
No occupation was strongly associated with low diet quality. Moderate but relatively imprecise associations were observed for women employed in management (OR: 1·3; 95 % CI: 1·1, 1·7); arts, design, entertainment, sports and media (OR: 1·4; 95 % CI: 0·9, 2·1); protective service (OR 1·3; 95 % CI: 0·7, 2·5) and farming, fishing, and forestry occupations (OR: 0·5; 95 % CI: 0·2, 1·1).
Our analyses suggest that women in certain occupations may have lower diet quality in the months before pregnancy. Further research is needed to determine whether certain occupations could benefit from interventions to improve diet quality in the workplace for women of reproductive age.
已知妊娠结局的孕产妇风险因素因就业状况而异。我们在一个基于人群的样本中评估了孕前饮食质量是否因职业不同而有所差异。
我们分析了一项关于妊娠结局的全国性病例对照研究中7341名母亲的访谈数据。孕前3个月内的自我报告工作按照标准职业分类（SOC）代码进行分类。孕前一年的日常饮食通过半定量食物频率问卷进行评估，并使用妊娠饮食质量指数（DQI-P）进行评价。我们采用逻辑回归计算调整后的比值比（OR）和95%置信区间（CI），以估计低饮食质量（定义为DQI-P得分的最低四分位数）与职业类型之间的关联。

1997年至2011年间分娩婴儿的就业母亲。
没有哪种职业与低饮食质量有强烈关联。在从事管理工作的女性中观察到中度但相对不精确的关联（OR：1.3；95%CI：1.1，1.7）；艺术、设计、娱乐、体育和媒体行业（OR：1.4；95%CI：0.9，2.1）；保护服务行业（OR 1.3；95%CI：0.7，2.5）以及农业、渔业和林业职业（OR：0.5；95%CI：；0.2，1.1）。
我们的分析表明，某些职业的女性在孕前几个月可能饮食质量较低。需要进一步研究以确定某些职业是否能从改善育龄女性工作场所饮食质量的干预措施中获益。
