Infants of adolescent mothers are at increased risk for negative developmental outcomes. Given the high rate of pregnancy among Mexican-origin adolescent females in the US, the present study examined health characteristics at birth and developmental functioning at 10 months of age in a sample of 205 infants of Mexican-origin adolescent mothers. Infants were relatively healthy at birth and had near average developmental functioning at 10 months. The educational attainment of adolescents and their mothers, and infants' temperamental regulation, promoted positive developmental functioning, while the combination of low adolescent parental self-efficacy and high infant temperamental negativity was associated with greater developmental delay. Findings are discussed with respect to implications for prevention with this at-risk population of mothers and infants.
青少年母亲所生的婴儿出现负面发育结果的风险更高。鉴于美国墨西哥裔青少年女性的高怀孕率,本研究调查了205名墨西哥裔青少年母亲所生婴儿的出生时健康特征和10个月大时的发育功能。婴儿出生时相对健康,10个月时发育功能接近平均水平。青少年及其母亲的教育程度以及婴儿的气质调节促进了积极的发育功能,而青少年父母自我效能感低和婴儿气质消极性高的组合与更大的发育延迟有关。针对这一母婴高危人群的预防意义对研究结果进行了讨论。
