Latin America has notably elevated rates of adolescent fertility and obesity in women. Although numerous studies document associations between adolescent fertility and obesity across the life course, the pathways explaining their association are insufficiently theorized, especially regarding the factors in Latin America that may underpin both. Additionally, much of the existing research is from high-income countries, where fertility and obesity are trending down. In this paper, we review the various complex pathways linking adolescent fertility and obesity, highlighting research gaps and priorities, with a particular focus on Latin American populations. We carefully consider pregnancy's distinct impact on growth trajectories during the critical period of adolescence, as well as the cumulative effect that adolescent fertility may have over the life course. We also articulate a pathway through obesity as it may contribute to early puberty and thus, to adolescent fertility. If obesity is a cause of adolescent fertility, not a result of it, or if it is a mediator of early-life exposures to adulthood obesity, these are critical distinctions for policy aiming to prevent both obesity and early fertility. Research to better understand these pathways is essential for prevention efforts against obesity and undesired adolescent fertility in Latin America.

青少年生育力与肥胖之间的交叉点——关注拉丁美洲人口的途径和研究差距
拉丁美洲的青少年生育率和女性肥胖率显着升高。尽管大量研究记录了青少年生育力与肥胖在整个生命过程中的关联，但解释其关联的途径还没有得到充分的理论化，特别是在拉丁美洲可能支撑两者的因素方面。此外，现有的大部分研究来自高收入国家，这些国家的生育率和肥胖率呈下降趋势。在本文中，我们回顾了青少年生育能力和肥胖之间的各种复杂途径，强调了研究差距和优先事项，特别关注拉丁美洲人口。我们仔细考虑怀孕对青春期关键时期生长轨迹的独特影响，以及青春期生育能力在整个生命过程中可能产生的累积影响。我们还阐明了肥胖的途径，因为它可能导致青春期提前，从而影响青少年的生育能力。如果肥胖是青少年生育的原因，而不是其结果，或者如果肥胖是生命早期暴露于成年肥胖的中介因素，那么这些都是旨在预防肥胖和早期生育的政策的关键区别。更好地了解这些途径的研究对于拉丁美洲预防肥胖和不良青少年生育的努力至关重要。
