Around 48% of all pregnancies in low- and middle-income countries are unintended. Unintended pregnancy may contribute to lower use of antenatal care (ANC); however, current research in the area is largely inconclusive due to the methodological approaches applied.
Responses from 4493 women extracted from the 2014 Bangladesh Demographic and Health Survey (BDHS) were used to assess the association between unintended pregnancy and subsequent uptake of at least one and at least four skilled ANC visits. For this, Bayesian multilevel logistic regression models with informative priors (representing a range of values within which the researcher is certain the true effect of the parameters included lies) were used, adjusting for other factors that affect ANC uptake. Informative priors were selected from the BDHS data collected in 2004, 2007, and 2011.
Around 64% of women in Bangladesh who had at least one pregnancy within 3 years prior to the survey (that ended in a live birth) received ANC at least once, and of these around 32% used ANC at least four times. Mistimed (aOR, 0.73, 95% Cred I, 0.66-0.81) and unwanted (aOR, 0.69, 95% Cred I, 0.64-0.75) pregnancy were associated with reduced odds of attending the recommended minimum of four skilled ANC visits compared with wanted pregnancy. These likelihoods were even lower for at least one skilled ANC visit among women with a mistimed (aOR, 0.59, 95% Cred I, 0.53-0.65) or an unwanted pregnancy (aOR, 0.67, 95% Cred I, 0.61-0.74) than women with a wanted pregnancy.
In Bangladesh, more than one-quarter of women who report an unintended pregnancy at conception and do not terminate the pregnancy are at high risk of not using ANC. It is important for policies to include women with unintended pregnancy in mainstream healthcare services. This will increase the use of ANC and reduce associated adverse consequences.
在低收入和中等收入国家,约48%的怀孕是意外怀孕。意外怀孕可能导致产前保健(ANC)利用率降低;然而,由于所采用的方法,该领域目前的研究大多没有定论。
从2014年孟加拉国人口与健康调查(BDHS)中提取的4493名女性的回答,用于评估意外怀孕与随后至少进行一次和至少四次专业ANC检查之间的关联。为此,使用了具有信息先验(代表一系列值,研究人员确定所包含参数的真实效应在该范围内)的贝叶斯多层逻辑回归模型,并对影响ANC利用率的其他因素进行了调整。信息先验是从2004年、2007年和2011年收集的BDHS数据中选择的。
在孟加拉国,调查前3年内至少怀孕一次(以活产结束)的女性中,约64%至少接受过一次ANC检查,其中约32%至少使用过四次ANC检查。与预期怀孕相比,时机不当的怀孕(调整后比值比,0.73,95%可信区间,0.66 - 0.81)和意外怀孕(调整后比值比,0.69,95%可信区间,0.64 - 0.75)与进行至少四次专业ANC检查的几率降低有关。对于时机不当的怀孕(调整后比值比,0.59,95%可信区间,0.53 - 0.65)或意外怀孕(调整后比值比,0.67,95%可信区间,0.61 - 0.74)的女性,与预期怀孕的女性相比,至少进行一次专业ANC检查的可能性甚至更低。
在孟加拉国,超过四分之一在怀孕时意外怀孕且未终止妊娠的女性面临不使用ANC的高风险。政策将意外怀孕的女性纳入主流医疗服务很重要。这将增加ANC的使用并减少相关的不良后果。
