A high proportion of unwanted or unplanned pregnancies may be alcohol-exposed due to contraception failure or non-use. Nevertheless, data on contraception and alcohol use in the context of the risk of alcohol-exposed pregnancies are sparse.
To describe contraception use and alcohol consumption in sexually active non-pregnant women and investigate the factors associated with less effective contraception methods.
A cross-sectional national survey of women aged 18-35 years.
Data from non-pregnant women who were sexually active ( = 517) were analysed. Descriptive statistics were used to report demographics, consumption, and contraception measures. Logistic regression was used to investigate the factors associated with less effective contraception among drinkers.
The majority of participants were younger (46%), of NZ European ethnicity (78%), not in a permanent relationship (54%), with some or completed tertiary education (79%), employed (81%) and not users of the community services card (82%). Twenty-five percent of women were smokers, 94% consumed alcohol, and 72% binged at least 'monthly or less'. Most women used the pill (56%), and 20% of drinking women were using a contraception method with a 10% or more annual failure rate after 1 year of use. Women who binged 'weekly or more often' had similar odds of using less effective contraception as women who 'never' binged ( > 0.05). Younger Māori or Pacific women (odds ratio = 5.99; 95% confidence interval of odds 1.1531.2; = 0.033) and women who had no tertiary education (odds ratio = 1.75; 95% confidence interval of odds 0.003.06; = 0.052) had higher odds of using less effective contraception.
With 20% of women at risk of an alcohol-exposed pregnancy, public health measures to address alcohol consumption and the effective use of contraception are critical to reducing the risk for alcohol-exposed pregnancies in NZ.
由于避孕失败或未使用，相当一部分意外或非计划怀孕可能与酒精有关。然而，关于避孕和酒精使用与酒精暴露妊娠风险之间关系的数据却很少。
描述活跃期非妊娠女性的避孕措施使用和酒精消费情况，并调查与避孕效果较差相关的因素。
对年龄在 18-35 岁的活跃期非妊娠女性进行全国性横断面调查。
对 517 名活跃期非妊娠女性进行数据分析。采用描述性统计方法报告人口统计学、消费和避孕措施数据。采用逻辑回归分析调查饮酒者中避孕效果较差的相关因素。
大多数参与者年龄较小（46%），新西兰欧洲裔（78%），非固定关系（54%），接受过部分或高等教育（79%），就业（81%），未使用社区服务卡（82%）。25%的女性吸烟，94%的女性饮酒，72%的女性至少“每月或更少”狂饮。大多数女性使用避孕药（56%），20%的饮酒女性在使用避孕方法 1 年后每年失败率为 10%或更高。每周或更频繁狂饮的女性与从不狂饮的女性使用避孕效果较差的方法的几率相似（>0.05）。年轻的毛利或太平洋岛裔女性（比值比=5.99；95%置信区间比值 1.1531.2；=0.033）和未接受高等教育的女性（比值比=1.75；95%置信区间比值 0.003.06；=0.052）使用避孕效果较差的方法的几率更高。
20%的女性有酒精暴露妊娠的风险，因此，采取公共卫生措施来解决酒精消费问题和有效使用避孕措施，对于降低新西兰酒精暴露妊娠的风险至关重要。
