Identify new ways to increase the impact of pregnancy prevention interventions on the number of children born to adolescents.
The study participants, a racially/ethnically diverse group of 1,568, pregnant 13-18 year olds, reported why they had not used contraception at the time of conception. Their explanations were sorted into categories. The frequency with which each category was endorsed, the stability of these endorsements (Kappa statistic), and differences between adolescents who endorsed each category (stepwise logistic regression) were examined at two points in gestation.
"Not ready to prevent pregnancy" was the most frequently endorsed category; it was often the only category endorsed. Logistical barriers and misperceptions about the need for contraception were the least frequently endorsed categories. The reasons individual patients gave for not using contraception changed (K < or = 0.4) during gestation. Yet, adolescents who were not ready to prevent conception consistently differed from those who were; they were more apt to be Hispanic, to live in non-chaotic environments with an adult father of the child rather than their parents, and to have goals compatible with adolescent childbearing.
The most expedient way to strengthen the impact of pregnancy prevention programs on adolescent childbearing is to shift the focus of intervention from overcoming logistical barriers and misperceptions about the need for contraception, to helping young women develop goals that make adolescent childbearing a threat to what they want in life. This means intervening actively enough to ensure that goal setting translates into an internal desire to postpone childbearing beyond adolescence.
找出新方法,以增强预防怀孕干预措施对青少年生育子女数量的影响。
研究参与者为1568名年龄在13至18岁之间、种族/民族各异的怀孕少女,她们报告了受孕时未采取避孕措施的原因。她们的解释被分类整理。在孕期的两个时间点,研究了每个类别被认可的频率、这些认可的稳定性(卡帕统计量)以及认可每个类别的青少年之间的差异(逐步逻辑回归)。
“还没准备好预防怀孕”是最常被认可的类别;它常常是唯一被认可的类别。后勤障碍以及对避孕需求的误解是最不常被认可的类别。个体患者给出的未采取避孕措施的原因在孕期有所变化(K≤0.4)。然而,还没准备好预防怀孕的青少年与那些准备好的青少年始终存在差异;他们更有可能是西班牙裔,生活在非混乱的环境中,孩子的父亲是成年人而非他们的父母,并且有与青少年生育相符的目标。
加强预防怀孕项目对青少年生育影响的最便捷方法是将干预重点从克服后勤障碍和对避孕需求的误解,转向帮助年轻女性制定目标,使青少年生育成为她们生活追求的一种威胁。这意味着要积极干预,确保目标设定转化为推迟生育至青春期之后的内在愿望。
