Existing evidence highlights that exposure to secondhand smoke (SHS) is a risk factor for pregnant women's health and is possibly affected by individual characteristics. This study aimed to explore the effect of individual socioeconomic status (SES) on SHS exposure among pregnant women in the third trimester and the interaction effect of age.
A total of 678 nonsmoking pregnant women with a median age of 29.0 years from 14 communities in a medium-sized city were recruited for this survey. Exposure to SHS was defined as the self-reported smoking habit of a spouse/partner. Individual SES characteristics consisted of marital status, educational attainment, employment and per capita monthly income.
There were 238 (35.1%) participants who suffered from SHS exposure. Compared to the pregnant women who were employed, those who were unemployed were more likely to suffer from SHS exposure (OR = 1.572, 95% CI: 1.013-2.441). Participants who had a high school or technical secondary school education were more likely to be exposed to SHS than those with a college education or above (OR = 1.601, 95% CI: 1.029-2.449). Advanced age was a protective factor for participants with a college education or above (OR = 0.939, 95% CI: 0.884-0.997), but age increased the risk of SHS exposure among women who had unstable marriages (OR = 1.256, 95% CI: 1.019-1.549).
Exposure to SHS was very common among pregnant women in the third trimester. Pregnant women with a low SES and an older age should be considered a key population for the implementation of public health interventions.
现有证据强调，接触二手烟（SHS）是孕妇健康的一个风险因素，并且可能受到个体特征的影响。本研究旨在探讨个体社会经济地位（SES）对孕晚期妇女接触 SHS 的影响，以及年龄的交互作用。
共招募了来自一个中等城市 14 个社区的 678 名非吸烟孕妇，她们的中位年龄为 29.0 岁。暴露于 SHS 的定义是配偶/伴侣的自我报告吸烟习惯。个体 SES 特征包括婚姻状况、受教育程度、就业和人均月收入。
有 238 名（35.1%）参与者遭受 SHS 暴露。与就业的孕妇相比，失业的孕妇更有可能遭受 SHS 暴露（OR=1.572，95%CI：1.013-2.441）。具有高中学历或中等技术学校学历的参与者比具有大学学历或以上的参与者更有可能接触 SHS（OR=1.601，95%CI：1.029-2.449）。较高的年龄是具有大学学历或以上的参与者的保护因素（OR=0.939，95%CI：0.884-0.997），但年龄增加了不稳定婚姻中妇女接触 SHS 的风险（OR=1.256，95%CI：1.019-1.549）。
孕晚期妇女接触 SHS 的现象非常普遍。社会经济地位较低和年龄较大的孕妇应被视为实施公共卫生干预的重点人群。
