Influences of family structure dynamics on sexual debut in Africa : implications for research, practice and policies in reproductive health and social development : original research article
Bibliographic record
Abstract
There is no research on the timing, sequencing and number of changes in family environment and their influences on sexual and reproductive health outcomes in Africa. Using a population-based survey with data on family structure at three points in the life course, this paper examines the influences of these family structure dynamics on the timing of first sex among unmarried males and females aged 12-24 years in Cameroon. The number and timing of family transitions significantly impacted the timing of sexual debut for both males and females. The median age at first sex (18.7 years) is higher among young people without family transition than among those with one transition (18.2 years) or two transitions (17.7 years). Family transitions occurring during childhood were significantly associated with premature sexual initiation for females but not for males. Reproductive health and social development interventions for young people in Africa should integrate the changing contexts and transitions in family structure. Il n'existe pas des recherches sur l'occurrence, les sequences et le nombre de modifications des structures familiales ainsi que leurs influences sur la sante sexuelle et de reproduction en Afrique. A partir des donnees d'une enquete basee sur la population ayant collecte des informations sur les structures familiales a trois differents moments au cours de la vie chez les celibataires des deux sexes âges de 12 a 24 ans au Cameroun, cette etude examine les effets de la dynamique des structures familiales sur le debut de l'activite sexuelle. Le nombre de transitions familiales et leur occurrence sont significativement associes a l'âge au premier rapport sexuel tant chez les filles que chez les garcons. L'âge moyen au premier rapport sexuel est plus eleve chez les repondants n'ayant vecue aucune transition familiale (18,7 ans) que ceux qui ont connu une transition (18,2 ans) ou deux transitions familiales (17,7 ans). Une transition familiale survenue durant l'enfance influence l'entree en sexualite des familles, mais pas celles des garcons. Les activites d'intervention en sante de reproduction et developpement social des jeunes en Afrique doivent integrer les changements des contextes et transitions des structures familiales.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
