Mapping diversity in gender identity and gender roles across sex and age in the Dutch general population: a large-scale cohort study.

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
Background: Knowledge of diversity in gender identity and gender roles in the general population is limited. This study aimed to report the prevalence estimates of gender identity and gender roles among the adult general population, stratified by age and sex. Methods: In the third general assessment of the prospective Dutch Lifelines Cohort Study, conducted between 2019 and 2023, sex and current gender identity were assessed using a self-reported categorical item, in which participants aged 18 years and older could indicate their sex assigned at birth (male or female) and current gender identity (man or woman), or select the option with a free-text field. Two separate dimensional measures assessed adherence to feminine and masculine gender roles. Using a cross-sectional study design, we describe the distribution of gender identities and adherence to gender roles, stratified by age and sex as registered by the municipality. Differences herein are assessed via independent t-tests and ANOVA. Findings: A total of 63,190 participants (mean age = 55.4 years [SD = 12.6]) were included in the study. Most participants identified as cisgender (36,835 [58.6%; 95% CI = 58.2-58.9] cisgender women; 25,893 [41.2%; 95% CI = 40.8-41.6] cisgender men). 66 (0.11%; 95% CI = 0.08%-0.13%) participants identified as non-cisgender. Among cisgender participants registered as males, masculine gender role scores increased across age groups, with younger individuals (18-30 years) scoring lower (M = 9.3, SD = 1.2) than older individuals (71-97 years; M = 9.7, SD = 1.0; Interpretation: Although effect sizes are small, younger and female individuals indicate greater diversity in gender roles than older and male individuals, respectively. This shows that diversity in gender role adherence is common. A limitation of this study is the relatively older sample, which limits representation of younger individuals and may affect generalizability. These findings have implications for clinical practice and policy, as recognizing gender role diversity could help healthcare providers tailor interventions and assessments. Given the small but meaningful effect sizes, continued research on gender roles and their health impact across age groups is warranted to inform gender-sensitive policies.
