Prevalence and associated factors of early sexual initiation among female youth in Tanzania: a nationwide survey.
Article in BMC public health, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
backgroundEarly sexual initiation among female youth in Tanzania presents a significant public health concern, as it is associated with increased risks of unintended pregnancies, sexually transmitted infections and adverse socioeconomic consequences. This study aimed to determine the prevalence and associated factors of early sexual initiation among female youth in Tanzania.
methodsWe used data from the 2022 Tanzania Demographic and Health Survey, conducted between February 24 and July 21, 2022. The sampling frame was stratified by geographic region and urban/rural areas, using a two-stage sampling method that selected primary sampling units based on census enumeration areas, followed by household selection using probability systematic sampling. Data management and analysis were performed using STATA version 18.5, descriptive statistics, and a weighted logistic regression model to determine factors associated with early sexual initiation. Odds ratios (OR) and 95% Confidence intervals (CI) were used to estimate the strength of association.
resultsThe overall prevalence of early sexual initiation among female youth in Tanzania was 17.4%. In an adjusted analysis, female youth with no formal education had higher odds of having early sexual initiation (aOR = 3.09, 95%CI: 2.06-4.57) compared to their counterparts who had attained secondary/higher education. Conversely, female youth who were working (aOR = 0.81, 95%CI: 0.62-0.97), having media exposure (aOR = 0.74, 95%CI: 0.58-0.96), and increased in age (aOR = 0.91, 95%CI: 0.87-0.96) were associated with lower odds of having early sexual initiation.
conclusionThis study found a significant proportion of female youths who had early sexual initiation. Lack of education, increase in age, media exposure, and employment were associated with early sexual initiation. There is a great need for a multifaceted approach that includes educational reforms and comprehensive economic strengthening while addressing structural inequalities that increase sexual vulnerability in addressing early sexual debut among female youths..
