This study assessed the relationship between unintended pregnancy and infant birthweight in Ecuador, differentiating between unwanted and mistimed pregnancies.
Analyses focused on a subsample of women (n = 2490) interviewed in the 1994 Ecuador Demographic and Maternal-Child Health Survey. Logistic regression was used to assess the relationship between pregnancy intention status and low birthweight after control for other factors.
Infants from unwanted pregnancies were more likely than infants from planned pregnancies to have low birthweight (odds ratio = 1.64, 95% confidence interval = 1.22, 2.20). Mistimed pregnancy was not associated with low birthweight.
Unwanted pregnancy, but not mistimed pregnancy, is associated with low birthweight in Ecuador. Further research is needed to understand the mechanism through which pregnancy intention status affects birthweight.
本研究评估了厄瓜多尔意外怀孕与婴儿出生体重之间的关系，区分了意外怀孕和时机不当的怀孕。
分析聚焦于1994年厄瓜多尔人口与妇幼健康调查中接受访谈的女性子样本（n = 2490）。在控制其他因素后，使用逻辑回归评估怀孕意愿状态与低出生体重之间的关系。
意外怀孕的婴儿比计划怀孕的婴儿更有可能出生体重低（比值比 = 1.64，95%置信区间 = 1.22，2.20）。时机不当的怀孕与低出生体重无关。
在厄瓜多尔，意外怀孕而非时机不当的怀孕与低出生体重有关。需要进一步研究以了解怀孕意愿状态影响出生体重的机制。
