The impact of family functioning on fertility intentions among university students: a study based on latent profile analysis.
Article in BMC public health, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundPersistent low fertility in China poses critical socioeconomic challenges. Family functioning has been implicated in reproductive decisionmaking, yet its heterogeneity remain underexplored, particularly among young adults. This study employs Latent Profile Analysis (LPA) to identify high and lowfunctioning family profiles among Chinese university students and their parents, and to quantify their associations with marriageandchildbearing attitudes and explicit fertility intentions.
methodsIn a crosssectional survey of 484 student-parent pairs from two northwest Chinese universities, we administered a 68item questionnaire incorporating the 30item Chinese Family Assessment Device and standardized measures of fertility intentions and marriageandchildbearing views. LPA classified families into two profiles. Multinomial logistic regression (Models 1-3) tested the effect of family functioning on students' ideal number of children ("0," "1," "≥ 2," vs. "indifferent"), sequentially adjusting for student and parental sociodemographic covariates.
resultsLPA yielded two profiles: lowfunctining (57.0%) and highfunctoning (43.0%) families. In Model 1, lowfunctioning membership increased the odds of intending 0 children (R = 2.90, 95% CI 1.53-5.49, p < 0.01), 1 child (OR = 2.65, 1.51-4.63, p < 0.01), and ≥ 2 children (OR = 3.54, 2.28-5.49, p < 0.001) versus remaining indifferent. Adjusting for student factors (Model 2) attenuated the zerochild effect (p = 0.21) but retained significant associations for 1 child (OR = 2.22, 1.20-4.12, p < 0.05) and ≥ 2 children (OR = 3.08, 1.77-5.35, p < 0.001). In the fully adjusted model (Model 3), lowfunctioning status remained a predictor only of ≥ 2 children (OR = 2.57, 1.40-4.73, p < 0.01). Older parental age independently predicted zerochild intentions (OR = 1.20, 1.08-1.33, p < 0.001), while parental occupation moderated highintention outcomes.
conclusionsLow family functioning exerts a robust influence on both low and high fertility intentions, although its effect on zerochild plans is largely explained by student and parental characteristics. By uncovering multidimensional familyfunctioning profiles and their differential impacts, this study advances theoretical models of intergenerational value transmission and informs targeted familyeducation and policy interventions aimed at mitigating China's lowfertility trajectory.
