Pre-pregnancy obesity among immigrant and non-immigrant women in Norway: Prevalence, trends, and subgroup variations.
Observational study in Acta obstetricia et gynecologica Scandinavica, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
introductionThis study assessed prevalence and time trends of pre-pregnancy obesity in immigrant and non-immigrant women in Norway and explored the impact of immigrants' length of residence on pre-pregnancy obesity prevalence. MATERIAL AND
methodsObservational data from the Medical Birth Registry of Norway and Statistics Norway for the years 2016-2021 were analyzed. Immigrants were categorized by their country of birth and further grouped into seven super regions defined by the Global Burden of Disease study. Pre-pregnancy obesity was defined as a body mass index ≥30.0 kg/m
resultsAmong 275 609 pregnancies, 29.6% (N = 81 715) were to immigrant women. Overall, 13.6% were classified with pre-pregnancy obesity: 11.7% among immigrants and 14.4% among non-immigrants. Obesity prevalence increased in both immigrants and non-immigrants during the study period, with an average yearly increase of 0.62% (95% confidence interval [CI]: 0.55, 0.70). Obesity prevalence was especially high in women from Pakistan, Chile, Somalia, Congo, Nigeria, Ghana, Sri Lanka, and India (20.3%-26.9%). Immigrant women from "Sub-Saharan Africa" showed a strong association between longer residence length and higher obesity prevalence (≥11 years (23.1%) vs. <1 year (7.2%); adjusted PR = 2.40; 95% CI: 1.65-3.48), particularly in women from Kenya, Eritrea, and Congo.
conclusionsPrevalence of maternal pre-pregnancy obesity increased in both immigrant and non-immigrant women from 2016 to 2021. Several immigrant subgroups displayed a considerably elevated obesity prevalence, placing them at high risk for adverse obesity-related pregnancy outcomes. Particular attention should be directed towards women from "Sub-Saharan Africa", as their obesity prevalence more than doubled with longer residence.
